The Alpha Magnetic Spectrometer (AMS) studies cosmic rays from the ISS
When something goes wrong in a complex $2 billion physics experiment on Earth, it's a huge challenge. These challenges are compounded when the physics test falls on the International Space Station, which orbits 250 miles above Earth. Thanks to the efforts of the reckless crew on the International Space Station, who walked into space for repairs, the damaged particle detector came to life.
A new six-part documentary series on Disney+ describes the challenges the crew have faced on this mission over the past two years. The series also chronicles the last spaceflight of veteran NASA astronaut Chris Cassidy, which took place just as the COVID-19 pandemic forced the world into quarantine. "I'm kidding three years ago, I knew I was going to be quarantined in March 2020," Cassidy told Ars. "I didn't know the whole world would join me."
As previously reported, the Alpha Magnetic Spectrometer (AMS) is a particle detector that landed on the International Space Station in 2011 on the last space shuttle flight. The instrument has been continuously collecting data for the past six years, examining various particles from various sources, including dark matter collisions. Ting, AMS consists of layers of smaller detectors and is designed to measure the energy and trajectory of cosmic ray particles, including high-energy photons, electrons and positrons (the antimatter partners of electrons). It also has a set of high-quality magnets that direct the path of electrically charged particles and help separate the stock from different types of particles. The detectors allow researchers to distinguish between positrons, protons (which have the same positive charge but different masses), electrons (which have a negative charge), and other particles.Read more Particle detectors in space have different dark matter news
In 2014, the AMS team announced the results of its first 18 months of data collection. It turned out to be very ambiguous. As Matthew Francis wrote for Ars at the time, "While AMS-02 found more than a certain amount of particles expected from some models of dark matter destruction, it exceeded the expected properties of a dark matter signature." So, there is some interesting information. In AMS-02, but the probability of it being dark matter seems a bit low. ', to get more specific results. In 2017, scientists monitored AMS's $2 billion instrument to further "degrade" many of the pumps powering the thermoelectric cooling system on its silicon detector. Three of the four pumps were essentially broken. They were Only one is needed, but the cooling system has lost all its abundance. Finally, the fourth pump showed signs of failure. src="https://safirsoft.com/picsbody/2110/10846-1.jpg" alt="https://safirsoft.com Among the events, the stars do a mission Bold in space to fix physics experiment" srcset="https://cdn. arstechnica .net/wp-content/uploads/2021/10/betweenA.jpg 2x "> Zoom in / Nobel Laureate Samuel Ting A physicist testing the Alpha Magnetic Spectrometer (AMS) on the International Space Station.

So the physicists involved in the experiment worked with a team at NASA to design a long-term strategy that would extend the life of the AMS. They knew that installing a new set of pumps would require relatively labor-intensive work, including removing insulation, all of which required a lot of hiking. European Space Agency astronaut Luca Parmitano and NASA astronaut Andrew Morgan were the astronauts on the mission, assisted by NASA astronauts Christina Koch and Jessica Meir, who were responsible for the robotic arm from inside the International Space Station.
He was on Earth, And director Ben Turner is ready to shoot everything with camera, including videotapes and live footage.The star producer and CEO admits to his constant obsession with spaceflight, and one of the highlights of his filmmaking career was shooting a music video for NASA's One Direction. This is his appetite for more. "As a documentary filmmaker, I have the ability to go to great places and tell the story of wonderful people and try to see the world through their eyes," he says. "My long-term dream has been to do this with NASA."
He got his chance when one of his corporate partners, James Corden (better known as Peter the Rabbit), was talking to Peter Rabbit's manager. Will Glock said on the filming of Glock that he met Cassidy. Knowing that Turner was a huge fan of space, Corden contacted Glock to learn about the astronaut. Soon Cassidy joined the project.
