Joint Base Charleston serves two factions of the US military: the air force and the navy. Prior to 2010, Charleston Air Force Base and the Navy had separate facilities for naval support activities in Charleston. This joint base is the result of their merger. However, the jurisdiction of the base belongs to the Air Force. Joint Base Charleston is located near Charleston, South Carolina, and also shares the runway with Charleston International Airport.
The Airlift Wing controls the leading active flying wings in the base, flies and maintains a large fleet of C-17 aircraft, which is one of the largest in the entire Air Force. This played a very important role for Joint Base Charleston, as the fleet provided a large part of the Air Force Mobility Command’s global reach airlift capabilities. Their mission is to provide safe, reliable and accurate air transportation to anywhere in the world.
Their C-17 fleet contains approximately 41 aircraft. The value of the fleet is approximately US$9.2 billion. Each aircraft is only worth 212 million U.S. dollars. Every three minutes during the day or night, there will be one of 437 planes
Airlift wing is taking off or landing around the world. These aircraft usually carry humanitarian supplies, war supplies, troops or medical personnel. In the event of trouble or conflict, Charleston’s aircraft are usually those that are required to provide assistance in some way.
The C-17 fleet is powerful and can carry various types of bulk cargo. It can accommodate two large buses, one large army tank or three helicopters for reference. This means that these planes are simply huge, so big that it is hard to imagine if you don't see them with your own eyes. One of the aircraft has a tail height of more than 55 feet, a cockpit height of about 20 feet, and a wingspan of nearly 170 feet.
When fully loaded, a C-17 can hold approximately 600,000 pounds on the ground, with a maximum load of 170,900 pounds. It can also land in unstable places, even with a full load on a runway as short as 3,000 feet. Now this is an impressive machine. Operate these 437
The Airlift Wing has 1,300 employees, some of whom are military and some civilians. They all support the Department of Defense’s tactical airdrops, aeromedical evacuation support, and global airlift.
There is no doubt that humans feel the need for speed. From the first time we sat down to choosing the roller coaster priority at Magic Mountain, speed was always the primary factor.
However, when the "rypto escape" journey ended, most of us had to stop resisting the impulse of speed, and others began to go out and design objects and vehicles much faster than we thought.
Remember, when you read this list, the M4 carbine fires one bullet at a speed of 2,025 miles per hour.
The X-43 A is the fastest aircraft ever. It is driverless and is designed to test breathing engine technology in the following locations
, Although the speed of the aircraft may reach Mach 10. NASA hopes to use the information collected from its three X-43 to design a fuselage with a larger payload, and ultimately design a reusable rocket.
In order to make any object in low earth orbit stay in low earth orbit,
. The outer fuel tank of the space shuttle contains more than 500,000 gallons of liquid oxygen and liquid hydrogen, which are mixed and burned as fuel for the three main engines.
The Apollo 10 mission in May 1969 witnessed the fastest manned spacecraft ever. Apollo 10 is an empty road to the moon, simulating all the events required to land on the moon. The people on the boat are
From now on, unmanned vehicles.
Anything designed to collect comet samples must be designed to increase speed. Stardust aims to capture a comet, collect a sample, and then
-It did it in 2006. This kind of capsule has reached the fastest speed of all man-made objects returning to the earth's atmosphere-36 Mach.
The navigator is also fortunate to be the most traveled man-made object in history. It was launched in 1977 and reached the interstellar labyrinth space in 2013. It covers more than 322 million miles per year.
In a nuclear bomb test called Operation Plumb, Robert Brownlee was responsible for designing a test to limit nuclear radiation from underground explosions. Place the device in a deep pit with a four-inch iron manhole.
Apparently, the lid popped out during the explosion, but Brownlee wanted to test the speed of the expelled lid. The test was taken with a camera, which captures one image every millisecond, and only one frame captures the iron cover.
Brownlee calculated that its speed was 125,000 mph, and it was likely to reach space,
. They never found it.
The first of two satellites designed to study the sun. The two Helios satellites were also designed in the 1970s
Even closer to the sun than Mercury. It only took two years for the exploration to reach the sun, and it was not until 1985 that they transmitted information about the heliosphere.
They don't do it like they used to.
I hope I can rescue my soldiers.
I became a platoon leader when I was 22, and in 2010 I was responsible for supervising and caring for 40 soldiers participating in the battle. At that time, I only made one trip in Iraq for a total of 12 months. But many of my soldiers have served four to five times and have seen and heard much more than me.
Our job is to drive on the international highway connecting Kuwait and Iraq, and build relationships with local Iraqi police and chiefs. But we must also check improvised explosives or improvised explosive devices.
We don’t have everything. In one case, before the mission, a US envoy truck entered our base, half of it was killed and torn to pieces. In the back: three corpses. We missed the IED.
Seeing such a thing has a lot of inner feelings, it may lead to a major symptom of post-traumatic stress disorder, called mor regret of survivors. In the military, especially for those deployed, the brain and body are worn out.
However, if you have ever suggested talking to a therapist, it will be difficult to find many service members who will help you. In the military, access to mental health treatment is seen as a weakness-apart from negative stigma, this is completely wrong. Some soldiers will try treatment, just leave after a meeting, and then say: "I don't feel well. I need to go back to the unit. I need help. I can spend an hour with my family."
Within a few years, someone in my unit committed suicide. It has been seven years since I left Iraq. During that time we lost two people in our army, one of whom was directly supervised by me.
As the platoon leader, I regard caring for our soldiers as my duty to complete the mission. This is my responsibility. But with the news of the suicide, I felt that I had failed as a leader. It is my responsibility to take care of these guys, just like they take care of us.
After retiring in 2015, I went to business school in Philadelphia. It has become my task to find out how I can make our soldiers know that the treatment is actually effective for them, even if they only stick to it. Just as you will not return to your normal daily work after a broken arm and a course of treatment with a physical therapist, you will not fully recover after a course of treatment with a mental health professional.
However, I quickly realized that in order for soldiers to receive treatment and stay there, they need to witness the progress they have made with their own eyes.
I carefully read a study that shows how you can use EEG technology to measure the electrical activity of the brain and also measure people's emotions. That's when a light bulb just goes out, for example, "Damn, you can make your mental health black and white like a broken arm."
This means that the therapist can objectively measure and track the patient's condition. By doing so, they can eliminate this negative stigma and bring more hope to people.
So i developed
. The idea is simple: provide therapists with a technique that uses basic and affordable medical supplies, such as EEG or heart rate monitors, to check the health of their clients. In this way, patients can see their heartbeat in real time when talking about traumatic things. Then, throughout the session, they will be able to see their heart rate slow down and return to a more relaxed state after recovery.
This is my new mission: to help the veterans community. 20 veterinarians committed suicide in the U.S.
, There is still a lot of work to be done. So I can't completely say that my task has been completed....
The vast oceans of the world provide a seemingly endless space in which American enemies can maneuver without being noticed. The US military has deployed manned and unmanned platforms and sensor networks to monitor enemy activities, but the scale of the task is arduous, and hardware alone cannot meet all the demands in a dynamic marine environment. However, marine life offers potential new advantages. Marine life is highly adapted to the surrounding environment-survival depends on life-a new plan of the DARPA Office of Biotechnology aims to use its natural perception capabilities to detect and signal that activities of interest occur in strategic waters such as straits and coastal areas area.
The Persistent Aquatic Biosensor (PALS) project led by project manager Lori Adornato will study natural and modified organisms to determine which organisms can best support the detection of manned and unmanned underwater vehicles Motion sensor system. PALS will investigate the reactions of marine organisms to such vehicles and characterize the generated signals or behaviors so that they can be captured, interpreted and relayed through a network of hardware devices.
In addition to being ubiquitous, sensor systems built around living organisms will provide many advantages over hardware alone. Marine organisms adapt and respond to their environment, and are capable of self-replication and self-sustainment. Evolution has enabled marine organisms to perceive stimuli across domains, including touch, electricity, sound, magnetism, chemistry, and optics. Even extremely low light does not pose an obstacle to creatures that evolve into hunting and avoiding in the dark.
However, assessing the perception of marine life is only one of the challenges for PALS researchers. Teams of performers supporting DARPA must also develop hardware, software, and algorithms to transform biological behaviors into actionable information, which can then be communicated to end users. The deployed hardware system operates at an isolation distance of up to 500 meters and must collect signals of interest from related species, process and distill them, and then relay them to remote end users. A complete sensing system must also distinguish between the target vehicle and other stimuli (such as debris and other marine life) to limit the number of false alarms.
Adornato aims to demonstrate this method and its advantages in a real environment to convey military use.
"Our ideal solution for PALS is to use a wide variety of native marine life without training, placement or modification in any way, which will open up this type of induction in many places," Adornato said.
DARPA agrees with the proposal to use natural organisms, but the proponents can suggest changes. To the extent that the researchers do propose a solution that can adjust the organism reporting mechanism, the proponent will be responsible for formulating appropriate environmental safeguards to support future deployments. However, in the PALS program, DARPA will never test modified organisms outside of a closed biosafety facility.
DARPA predicts that PALS will be a four-year basic research program that requires contributions in the fields of biology, chemistry, physics, machine learning, analysis, oceanography, electromechanical engineering, and weak signal detection.
These NASA Hubble Space Telescope images compare two different views of the rotating heart of a huge stellar nursery known as the Lagoon Nebula. These images were taken with visible light and the other was taken with infrared light to celebrate the 28th anniversary of Hubble's space flight.
The color visible light image on the left reveals the fantasy landscape of ridges, cavities, and mountains of gas and dust. This dust and gas landscape is carved by powerful ultraviolet radiation and hurricane-like stellar winds, released by a young monster star. Located in the center of the photo, this star is called Herschel 36 and is about 200,000 times brighter than our sun. This heavy star has a mass 32 times greater than our sun and a temperature of 40,000 Kelvin. Herschel 36 is still very active because it is still very young by the standards of a star, only one million years old.
Blazing radiation and powerful stellar winds (subatomic particle streams) push dust into the curtains. When the monster star abandons its nascent material cocoon, it is inhibiting the formation of surrounding stars.
However, on the dark edges of this vibrant bubble-like ecosystem, stars formed in dense clouds of gas and dust. The dark, elephant-like "bulk" material represents densely packed cocoon-like fragments that can withstand the scorching ultraviolet rays and act as an incubator for chicks.
The star-filled image on the right taken by Hubble in near-infrared light shows a very different view of the Lagoon Nebula compared to its visible portrait. Infrared observations of the universe allow astronomers to penetrate huge clouds of gas and dust to discover hidden gems. Hubble’s perspective gives us a glimpse into the amazing vistas that NASA’s James Webb space telescope can provide.
Although NASA is known for studying the distance of the solar system, it has trained countless satellites on Earth and provided scientists with a cornucopia of data about our changing planet.
But sometimes, science and art are not very different. In November 2017, the Global Climate Change Group of the National Aeronautics and Space Administration (NASA) released the most amazing images taken by satellites and astronauts in space.
Many of these images are in pseudo-color, which scientists use to show images and features that are not normally visible to the naked eye.
This is our selection of the best combination:
Not long ago, the British and Russians exchanged rubbish talks about the carrier. It all started when the then Defense Minister Michael Fallon called Admiral Kuznetsov "
. The Russians responded to this, calling it the first new aircraft carrier of the Royal Navy, the Queen Elizabeth,
"And warned the British to keep their distance.
Now, both operators have encountered problems. If you are a faithful WATM reader, please follow
. We are talking about the first deployment with two characteristics
Not to mention
The carrier is
However, the Queen Elizabeth has a problem of its own. There is no plane. In fact, she may have to operate the F-35B of the US Marine Corps, which requires some adjustments. Any battle here is difficult to fight, but give the British an advantage. Once the F-35 has cleared Kuznetsov’s wings (largely because they are much more advanced than MiG-29 and Su-33), Kuznetsov will only use 12 SS-N-19 Shipwreck missile. No problem for Queen Elizabeth's escorts.
But what is the fare of Kuznetsov for the US aircraft carrier? If anything, it's even more like a massacre. According to the provisions of the 16th edition of "World Combat Fleet", Kuznetsov can carry 18 Su-33 flanks or MiG-29K pivots, 4 Su-25 frogfoot trainers, and 15 Ka-27 Helix in the early days. ASW helicopter and 2 Ka-31 Helix airborne warning choppers.
In contrast, it should be noted that a typical American aircraft carrier wing has four F/A-18E/F Super Hornet or F/A-18C Hornet strike fighter squadrons, each with more than a dozen squadrons. Use fighter. Therefore, the Russians fought with the wrong odds of eight to three. By the way, the wings of this American aircraft carrier do provide electronic warfare assets.
Once Kuznetsov’s fighters are gone, the US aircraft carrier can launch an Alpha strike to sink Kuznetsov, or support the attack of B-1B Lancers carrying LRASM. Either way, Kuznetsov is falling. Oops, even old-fashioned midway-class aircraft carriers can ride Kuznetsov.
Since the first tank prototype rolled off the assembly line in 1915, the armored vehicles have captured the enemy forces on the battlefield where they were deployed.
In modern warfare, the M1A1 Abrams is currently our tank of choice. Its weight is close to 68 tons, which is equivalent to 29 Toyota Corollas.
The M1 series tanks are equipped with a 1500 horsepower engine, and are equipped with a 105mm main gun (some with a 120mm cannon) and three auxiliary machine guns. The beast on this battlefield requires four people to operate, and the price is about 9 million US dollars.
If you think the Abrams are huge, wait until you see these next armored behemoths.
Looking back at the First World War, the French developed Char 2C.
"Expansion pack. Although it was designed in 1917, the first device was not built until three years after the end of the war.
Char 2C weighs 69 metric tons, which is slightly heavier than the M1A1 we use today. It features a 75mm main gun and is equipped with four auxiliary machine guns at the front, rear and sides of the vehicle.
It is 33 feet long and 10 feet wide, and requires 12 personnel to fully operate the machine.
The tanks made by the German army were so large that they could not be transported invariably. It must be divided into six separate parts.
This tank is called K Wagen, and once the tank arrives near the battlefield by rail, the Germans must quickly assemble the armored car before the assembly is complete.
K Wagen weighs 120 metric tons, twice that of Abrams, and is close to 43 feet in length-slightly less than the width of a standard basketball court.
The weapon is as impressive as its size. K Wagen’s shells are equipped with four 77mm fort guns and seven MG08 machine guns.
Fortunately for the Allies, the war ended before this huge technology was tested on the battlefield.
When the Second World War broke out, the Germans designed the heaviest tank to date, the Maus Eighth Armored Division. This monster weighs 188 metric tons. This is 3.5 times that of our standard Abrams. The tank is equipped with a 128mm main gun, capable of destroying any armored vehicle of the era at a distance of no more than 2 miles.
The skin is made of nearly 9 inches of hard armor.
Due to its large size, the transportation of the armored vehicle is restricted because it usually collapses in the bridges and other buildings it rides.
Do you think the story of these monster tanks is over? Think again.
Meet Landkreuzer P.1000 Ratte.
Landkreuzer P.1000 Ratte. (source:
The tank was personally approved by Adolf Hitler and weighed 1,000 metric tons. 16 times heavier than our Hyundai M1A1 Abrams.
The ammunition of the tank alone is dedicated to about 300 metric tons. According to reports, the plan is to make the length of the Landkreuzer P.1000 Ratte 128 feet, which is longer than the length of a basketball court.
Fortunately, the tank was never produced, because although it was decided to be equipped with 8 anti-aircraft guns, it could be an ideal target for enemy aircraft raids.
See these monsters with your own eyes.
In August 2008, Norfolk, Virginia, police investigated the scene of the invasion and rape. The chief navy officer reported that she was attacked by an unknown male when she woke up. Before leaving, he threatened to hurt her and her teenage daughter if she reported him. Nearly a month later, the woman and her daughter entered their residence and found the perpetrator inside. He bound his daughter with duct tape and sexually assaulted her. Although the Sexual Assault Evidence Collection Toolkit (SAECK) was obtained from both women, and fingerprints were collected from the crime scene in both cases, there was no clue as to the identity of the attacker, and the case quickly changed It's very cold.
In April 2010, at the Arifjan camp in Kuwait, a female army captain was taking a bath when she turned and found an unknown man behind her. He was wearing a tan T-shirt wrapped around his head, covering his face. The man tried to drag her into the empty stall at the end of the trailer, but she fought back. In the ensuing struggle, she withstood multiple cuts and was hit in the head, but she was able to stop the attacker. The attacker fled the scene, and agents of the U.S. Army Criminal Investigation Command (CID) were immediately alerted. Agents observed a blood stain leading to a male toilet. The blood-stained tissue paper and stains on the sink indicate that the attacker has tried to clean it up. The agents also found a tan shirt with blood stains in a nearby trash can. Evidence collected from public toilets and mother toilets, blood stains and garbage bins has been submitted to
The analysis was conducted in Atlanta, Georgia.
Laboratory inspectors processed more than 60 submitted items for DNA, trace evidence, and potential blot analysis. DNA typing on blood evidence found inside and outside the male toilet determined that the blood type originated from an unknown male. The tan shirt in the trash can was stained with the blood of the same unknown man, as well as the blood of the victim, linking it to crime.
When the DNA profile of an unknown male is submitted to the Combined DNA Indexing System (CODIS), it will be searched against the national database. CODIS is a general term used to describe the FBI's procedures for supporting criminal justice DNA databases and the software used to run these databases.
In September 2010, the Army CID agent of the Arifjan Battalion received a notification of a database match. The unknown DNA profile matches another crime scene sample-a DNA profile obtained from vaginal swab semen from a Norfolk case in 2008. The match between the cases did not provide the name of the suspect, but it did provide valuable clues. CID began a joint investigation with agents of the Naval Criminal Investigation Service (NCIS) to try to identify the stakeholders who were stationed at Camp Norfolk and Arifkan at the same time on the designated date, and to examine all undiscovered evidence at the 2008 crime scene . Checked by Norfolk Police Department.
There are tens of thousands of service members serving in these two installations within the specified time period, and the agent is looking for ways to narrow the search. USACIL coordinated the outsourcing of blood evidence obtained from the crime scene to perform ABO blood group analysis. This information is used to limit the number of active personnel to approximately 1,800 Type A males. The collection of blood samples of active personnel stored in the registration form of the armed forces DNA identification laboratory is only for the purpose of identifying the remains of active personnel, and criminal investigations cannot be legally conducted except in rare cases. Therefore, there is no easy way to search the DNA profile of a person of interest. CID and NCIS agents face the daunting challenge of collecting DNA reference samples from these 1,800 related personnel, most of whom have been transferred to other work locations around the world and submitted to USACIL for analysis.
By December 2013, because there were no new clues, the case became cold again. USACIL has processed more than 200 DNA references, but in the case of long-awaited cases, there are no matching reports. Potential prints collected by Norfolk PD were forwarded to the FBI for military service records. The FBI notified the NCIS navy guard Amin J. Garcia that he might be "struck." The NCIS agent believes that Garcia is an interested person, but wants to confirm that he matches an unknown DNA file before arrest.
When NCIS contacted USACIL's DNA casework department for advice on which secret DNA samples to collect, Garcia worked at the Naval Operations Support Center in the Bronx, New York. The NCIS agent cast a shadow on the suspect during lunch in the cafeteria, and took out a fork, a water glass and a cotton swab from the banana that was only partially eaten for DNA comparison. In December 2013, USACIL reported that the fork’s DNA matched the DNA profile in the blood collected from the crime scene in the Arifjan camp. In early 2014, PO2 Amin J. Garcia was arrested. His DNA data has been entered into CODIS and matched with samples from the Arifjan camp and Norfolk SAECK samples, which makes him related to the rape case in 2008 and the serious attack in 2010.
At the time of the second attack, Army CID agent Charles Rector was an agent of the Kuwait CID office at the Arifjan camp in Kuwait. Rector has now retired from the military and is the special head of the District Investigation Department, the Office of Security and Integrity, and the US Citizenship and Immigration Services. Although seven years have passed, he does remember the case.
"About a week before the redeployment in 2010, even though we carried out several sexual assaults during the year-long rotation, this attack was an extremely brutal attack in a densely populated area in District 6... For an incident It is very unusual to happen in busy areas in the evening," Rector said.
The principal said that he and his team faced many challenges during the investigation.
"Zone 6 is a temporary area for the equipment. In addition, there is a concert about 150 yards from the incident, and the concert ended about an hour ago," Rector said. "As a result, many military and contractors from several other smaller camps in Kuwait attended the meeting."
"At some point after my team redeployed and completed the initial laboratory work, the "strike" in the DNA recovered from the evidence recovered in Kuwait and the "unknown" in Norfolk a few years ago The attacks coincided-involving a female navy member and her daughter. Over the next few years, I tried to understand the US case from several different places."
The principal said: "I feel very excited and overwhelmed, especially for the victims." He said that the survey "is a good testament to the work done by CID, and "specially for the time proof of this attack." The motto of CID is "to do what must be done".
Dr. Evelyn Ridgley is a forensic biologist in the DNA department of USACIL and the DNA inspector assigned to the case. She checked the evidence submitted from the crime scene and found whether there was blood or possible contact DNA, which could be used to identify people of interest. She said that she always hoped to solve the case, and was surprised that the older ABO blood type check broke the case.
Richley said that the case faces many challenges.
Richley said: "One challenge is that I am studying evidence from three different crime scenes." "There are two scenes from Camp Arif-the shower room where the female captain was attacked, and the male toilet cleaned by the suspect; from Evidence obtained by the Army CID. Later, NCIS sent me evidence from the Norfolk crime scene when the teenage daughter was beaten and was not checked during the initial investigation. The agents did everything possible The clues tried to identify the attacker. Another challenge was to check the more than 200 DNA references sent to the laboratory and check them against the DNA evidence at the crime scene. I ended up publishing more than 14 DNA reports for this case."
In order to overcome these challenges, Ridgley said she maintains open communication with the agent of the case.
Richley added that for agents in the field, "If you have any questions, please call the laboratory and we will be happy to answer any questions about how to collect samples."
In August 2014, Garcia was convicted in the Norfolk Circuit Court for being raped and kidnapped in the 2008 crime. He was later sentenced to life imprisonment. He pleaded guilty and was sentenced to 20 years in prison for the attack in the Arifjan camp in February 2016. After a lengthy investigation involving multiple institutions, two different forensic laboratories, and multiple forensic examinations, justice was finally achieved.
FBI agents have drawn up a list of countries that pose the greatest cyber threats to the United States.
Business Insider spoke with Aristedes Mahairas, Special Agent in charge of the Special Operations/Network Department of the FBI in New York, about the cyber security situation in the United States.
He said that the United States has been threatened alive by cybercriminals, cyber terrorists, and defecting hacktivists, but the nation-state "tops the list of threats."
Mahairas said that in the past 12 years, "the computer intrusion incidents initiated by the state has increased significantly" because it has become an effective method for coordinating with traditional espionage activities and navigating opponents.
He said in an interview with Business Insider at the "Digital Business World Conference" in Madrid, Spain: "Network operations may be a relatively cheap and desirable means to achieve worrying goals."
Mahairas pointed to the four countries most capable of launching deadly attacks on the United States. They were captured on the map above, including Russia, China, Iran, and North Korea.
The following is a breakdown of these four countries and the different threats they pose to the United States:
"Russia is still the most advanced and technologically capable country. They are really good at hiding the digital breadcrumbs that caused them to return." Mahairas said.
FBI agents pointed out the Yahoo hackers,
Canadian hacker Karim Baratov who worked with Russia
Mahairas also emphasized another type of cyber attack: affecting operations. This caused Russia to interfere in the 2016 U.S. presidential election.
Mahelas said: "The Internet is a medium, and some nation-states have realized that this medium can be used as the ability to weaponize information stolen due to hacking."
"These influence operations are not new, but because of... modern social media, its scalability has been significantly improved."
The FBI agent added that the best way to eliminate influence operations is through transparency on platforms such as Facebook. He said: "We must introduce the target audience to knowledge about threats and provide an environment for critical judgment to make the target audience less vulnerable."
Until recently, China has launched extremely noisy cyber attacks. "China used to spread around your network, like a drunk thief knocking on the door and smashing a window to enter," Mahailas said.
, The country has changed its strategy. "Today, they operate in a more patient and methodical manner, similar to the deaths of a thousand people being cut," Mahelas continued.
A major attack pointed out by a former counterterrorism agent
At that time, Chinese officers stole American state secrets from fighter jets (including F-35 fighters).
In a series of attacks code-named "Byzantine Head", they carried out attacks, the economic impact of which is estimated to be about 100 million U.S. dollars (75 million pounds). According to Mahairas, this is a "very important thing".
Mahairas said that in recent years, as Iranian hackers' attacks on the United States have become more mature and targeted, their activities have "increased significantly."
This was proven in 2017
. He was accused of breaking into the company's network, leaking the "Game of Thrones" script, and demanding a ransom in Bitcoin worth $6 million.
Mahairas' FBI department led the investigation of Mesri and launched a prosecution against the hacker in November 2017.
If he leaves Iran, he is in danger of being arrested.
Although Mesri appears to be acting alone, Mahelas said that the FBI is increasingly worried about "mixed threats" in certain countries. This is when they work with criminal contract hackers to do "dirty work".
Despite the thawing of diplomatic relations in recent months, North Korea remains a major cyber threat to the United States. Mahelas said that the diplomatic health between the two common enemies has little to do with the way the nation-state conducts cyber activities.
The FBI agent explained: "Diplomacy will not affect their ability or desire to continue this activity." "What they are looking for is information, access and advantages. These are goals whether they are in the online world or not."
In 2017, this paralyzed many organizations around the world, especially the British health service.
In the end, Mahairas said that cybercriminals are not picky about their goals: “These nation-state actors are not only against the United States. Anyone is a fair game. What they do is usually the same, and I don’t think any of them. Nation-states will bring more specific threats."
Like civil flight, the ashtray on an airplane is meaningless. According to both
In the guidelines, smoking is prohibited during the flight. The no-smoking sign constantly ignites the desires of every smoker.
But... there is an ashtray on the plane.
In 1990, the United States banned smoking on all flights. In 2000, international airlines followed suit. But before that, smoking is allowed on the plane. Even in the military, the age is older
It is equipped with an ashtray and needs to be cleaned before each flight. John F. Kennedy
It is made of several "chimneys".
After thinking that the crashes of Varig Flight 820 and Air Canada Flight 797 were caused by smoking passengers, causing 123 and 23 deaths, respectively, the Federal Aviation Administration (FAA) guidelines changed.
New rules have been implemented, but the aircraft model is still required to be equipped with ashtrays... just not used.
However, if someone does the same, risking a $100,000 fine and the lives of everyone on board, then the stewardess needs a place to dispose of cigarette butts. Most of the trash can is confetti, so this is a bad idea (read: flammable).
Has jurisdiction over the U.S. military. Military operations are not subject to the guidelines of the Federal Aviation Administration (FAA), but they are willing to abide by the sincerity of flying in the national airspace of the United States.
Even if it is reduced to the size of the UH-60 Black Hawk, an ashtray will still be installed to comply with FAA guidelines. Military helicopters still treat cigarette butts as foreign debris and need to be handled properly to avoid damage to the aircraft.
DARPA, BAE Systems, and Air Force Research Laboratories are working to develop new computer simulations, algorithms, and advanced software to provide military decision makers with organized, near real-time information about the causes of wars and conflicts in combat scenarios.
The new software program utilizes a series of original data sources that are disconnected and are designed to use reasoning algorithms and simulations to analyze intelligence reports, academic theories, environmental factors, and detailed information from operating scenarios and other types of user input .
Jonathan Goldstein, senior chief scientist for autonomous control and estimation of BAE Systems, said in an interview: “This is about obtaining information from different sources, which is impossible for one person to consume in a short period of time. ."
The Air Force Research Laboratory recently signed a $4.2 million contract with BAE Systems to develop CONTEXT; DARPA is sponsoring BAE’s work.
An emerging product called "Exploration of Causality in Complex Operating Environments" (CONTEXT) simulates different political, territorial and economic tensions that often cause conflicts. These nodes or variables constitute a complex but intertwined tapestry of causes, including economic tensions, terrorism, tribal or religious conflicts, and issues related to resource or territorial disputes.
"This technology can evaluate different forms of causality and innovate it into a model of intertwined causality that exists in originally unrelated sources. We are building a model that can be quickly used by experts so that when new conflicts occur At this time, decision makers can understand the underlying problems." Goldstein said.
On the surface, the organization and execution of some analysis of the big data pool may remind people of AI, and CONTEXT will evaluate the user's material input without having to access large amounts of historical or stored data. Nevertheless, it seems to be able to perform a certain degree of automation and AI-like functions because it can organize and integrate different resources for human decision makers.
"This shortens the decision-making cycle. People are not good at maintaining complex causal models. The software creates a large cause map, evaluates methods and checks the potential consequences of a given method." Goldstein explained.
Nowadays, the development speed of automation and AI is usually close to the speed of lighting, usually described in terms of reducing the "cognitive burden", which means that they can quickly perform analysis and provide a series of program functions to present the commander's control capabilities.
At the same time, the cause of conflict is usually a complex by-product of a series of more subjectively determined variables that are affected by concepts, personalities, personal psychology, historical nuances, and larger sociological phenomena. This naturally raises the question of how far even the most advanced computer programs can explain these factors and other "less obvious" factors.
Leading AI and cybersecurity experts often say that advanced computer algorithms can analyze data and perform program functions quickly, much faster than human cognition-but there are still many things that are unique to human cognition. Humans solve problems, interpret emotions and sometimes react to certain variables in ways that the best computer technology cannot.
The causality of war is always over-determined. Even if advanced statistical regression analysis is performed on a very large data set, it is unlikely to accurately determine the cause of the conflict. "Cyber drive news.
At the same time, despite the natural limitations, using software and simulation to analyze data in this way is certainly by no means useless.
Rustic said that it will “take the right step in the right direction” and “any effort to update the war prosecution and stop the war plan will greatly contribute to the update of the anti-terrorism and regime building lessons learned. The army. It’s long overdue to understand how people and failed military groups react to strategies to win wars and ensure peace."
Rustic further elaborated that human understanding of certain elements of causality will undoubtedly have beneficial effects in many aspects. However, there are of course great limitations. Few people would disagree that there are many concepts, feelings, variables and subjective factors of causation. This highlights the widespread recognition that despite the rapid development of computer technology, machines still have many things. Can't solve it.
Rustici said: "The program will not have a major impact on understanding how to model further in the future."
The National Aeronautics and Space Administration (NASA) and the National Nuclear Safety Administration (NASA) of the United States Department of Energy have successfully demonstrated a new type of nuclear reactor power system that allows long-term crew missions to reach the moon, Mars and other regions.
NASA announced the results of the demonstration called ``KV Reactor Using Stirling Technology'' at a press conference held at its Cleveland Glenn Research Center on May 2, 2018. The Kilopower experiment was conducted at NNSA's Nevada National Security Site from November 2017 to March 2018.
"Safe, efficient and abundant energy will be the key to future robot and human exploration," said Jim Reuter, acting assistant administrator of NASA's Space Technology Mission (STMD) in Washington. "I hope that the Kilopower project will become an essential part of the development of the lunar and Mars power architecture."
Kilopower is a small, lightweight fission power system that can provide at least 10 kilowatts of electricity-enough to continuously power several ordinary households-for at least 10 years. ??????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? Four kV units will provide enough power to establish an outpost.
According to Marc Gibson, Glenn’s main Kilopower engineer, the groundbreaking power system is very suitable for the moon, because the moon’s night is equivalent to 14 days on the earth, so moonlight is difficult to generate electricity.
The prototype power system uses a solid cast uranium 235 reactor core, about the size of a paper towel roll. The passive sodium heat pipe transfers the heat of the reactor to the efficient Stirling engine, which converts the heat into electrical energy.
According to David Poston, chief reactor designer at the Los Alamos National Laboratory of the National Nuclear Safety Administration, the recent experiment in Nevada had two purposes: to prove that the system can use fission energy to generate electricity, and to show that the system is stable. And safe. No matter what environment you encounter
Poston said: "In terms of nominal and abnormal operation, we put all the power in the reactor, and KRUSTY passed in bright colors."
The Kilopower team conducted the experiment in four stages. The first two stages performed without power supply confirmed that every component of the system was operating as expected. In the third phase, the team added the ability to gradually heat the core before gradually entering the final phase. The experiment ended with a 28-hour full-power test, which simulated a task including reactor startup, acceleration to full power, stable operation and shutdown.
Throughout the experiment, the team simulated power reduction, engine failure and heat pipe failure, showing that the system can continue to operate and successfully handle multiple failures.
The Kilopower project is developing mission concepts and carrying out other risk reduction activities in preparation for possible future flight demonstrations. The project will remain part of STMD's "Game Changing" development plan, with the goal of transitioning to the "Technical Demonstration Mission" plan in fiscal year 2020.
Such a demonstration can pave the way for the future Kilopower system, which can power human outposts on the moon and Mars, including relying on
Produce local propellants and other materials.
The Kilopower project is a collaboration between Glenn and the NASA Marshall Space Flight Center in Huntsville, Alabama, and NNSA (including its Los Alamos National Laboratory, the Nevada National Security Site, and the Y-12 National Security Center).
