ЦитироватьNASA's Cold Atom Lab: The Coolest Experiment in the Universe

NASA Jet Propulsion Laboratory

Опубликовано: 27 июл. 2018 г.

NASA's Cold Atom Lab will produce clouds of ultra-cold atoms aboard the International Space Station to perform quantum physics experiments in microgravity. Atoms are chilled to about one 10 billionth of a degree above Absolute Zero, or about 10 billion times colder than the average temperature of deep space. At those temperatures, atoms behave in strange ways, allowing scientists to investigate the fundamental nature of matter. For more info about CAL, visit https://coldatomlab.jpl.nasa.gov/
Спойлер
The clouds of ultra-cold atoms CAL produces are called Bose-Einstein Condensates (BECs), a bizarre state of matter in which atoms exhibit quantum behavior at macroscopic a scale you can see. BECs make it possible for researchers to probe the fundamental nature of matter. Hundreds of BEC experiments exist on Earth, but on the International Space Station, free from the pull of gravity, scientists will be able to observe BECs for much longer than what is possible on Earth, and reach even colder temperatures than what is typically achieved on the ground. The Cold Atom Lab will move scientists another step closer to solving some of the biggest mysteries in the universe, such as understanding the nature of dark matter and dark energy and solving the disagreement between quantum mechanics and the theory of gravity.

Research done on CAL can also have practical applications, such as making improvements to atomic clock technologies, which are used in spacecraft navigation, as well as the GPS satellites that provide navigation information to devices like smartphones. CAL research could also lead to improvements to quantum sensors used for remote sensing on spacecraft. These sensors can be used for a variety of applications, including monitoring Earth's changing climate and remotely studying the internal makeup of planets and asteroids.

Space Station Experiment Reaches Ultracold Milestone

The International Space Station is officially home to the coolest experiment in space.

NASA's Cold Atom Laboratory (CAL) was installed in the station's U.S. science lab in late May and is now producing clouds of ultracold atoms known as Bose-Einstein condensates. These "BECs" reach temperatures just above absolute zero, the point at which atoms should theoretically stop moving entirely. This is the first time BECs have ever been produced in orbit.

This series of graphs show the changing density of a cloud of atoms as it is cooled to lower and lower temperatures (going fr om left to right) approaching absolute zero. The emergence of a sharp peak in the later graphs confirms the formation of a Bose-Einstein condensate -- a fifth state of matter -- occurring here at a temperature of 130 nanoKelvin, or less than 1 Kelvin above absolute zero. (Absolute zero, or zero Kelvin, is equal to minus 459 degrees Fahrenheit or minus 273 Celsius).

CAL is a multiuser facility dedicated to the study of fundamental laws of nature using ultracold quantum gases in microgravity. Cold atoms are long-lived, precisely controlled quantum particles that provide an ideal platform for the study of quantum phenomena and potential applications of quantum technologies. This NASA facility is the first of its kind in space. It is designed to advance scientists' ability to make precision measurements of gravity, probing long-standing problems in quantum physics (the study of the universe at the very smallest scales), and exploring the wavelike nature of matter.

"Having a BEC experiment operating on the space station is a dream come true," said Robert Thompson, CAL project scientist and a physicist at NASA's Jet Propulsion Laboratory in Pasadena, California. "It's been a long, hard road to get here, but completely worth the struggle, because there's so much we're going to be able to do with this facility."


The Cold Atom Laboratory (CAL) consists of two standardized containers that will be installed on the International Space Station. The larger container is called a "quad locker," and the smaller container is called a "single locker." The quad locker contains CAL's physics package, or the compartment where CAL will produce clouds of ultra-cold atoms.

CAL scientists confirmed last week that the facility has produced BECs fr om atoms of rubidium, with temperatures as low as 100 nanoKelvin, or one ten-millionth of one Kelvin above absolute zero. (Absolute zero, or zero Kelvin, is equal to minu 459 degrees Fahrenheit, or minus 273 degrees Celsius). That's colder than the average temperature of space, which is about 3 Kelvin (minus 454 degrees Fahrenheit/minus 270 degrees Celsius). But the CAL scientists have their sights set even lower, and expect to reach temperatures colder than what any BEC experiments have achieved on Earth.

At these ultracold temperatures, the atoms in a BEC begin to behave unlike anything else on Earth. In fact, BECs are characterized as a fifth state of matter, distinct fr om gases, liquids, solids and plasma. In a BEC, atoms act more like waves than particles. The wave nature of atoms is typically only observable at microscopic scales, but BECs make this phenomenon macroscopic, and thus much easier to study. The ultracold atoms all assume their lowest energy state, and take on the same wave identity, becoming indistinguishable from one another. Together, the atom clouds are like a single "super atom," instead of individual atoms.

Not a simple instrument

"CAL is an extremely complicated instrument," said Robert Shotwell, chief engineer of JPL's astronomy and physics directorate, who has overseen the challenging project since February 2017. "Typically, BEC experiments involve enough equipment to fill a room and require near-constant monitoring by scientists, whereas CAL is about the size of a small refrigerator and can be operated remotely from Earth. It was a struggle and required significant effort to overcome all the hurdles necessary to produce the sophisticated facility that's operating on the space station today."

The first laboratory BECs were produced in 1995, but the phenomenon was first predicted 71 years earlier by physicists Satyendra Nath Bose and Albert Einstein. Eric Cornell, Carl Wienman and Wolfgang Ketterle shared the 2001 Nobel Prize in Physics for being the first to create and characterize BECs in the lab. Five science groups, including groups led by Cornell and Ketterle, will conduct experiments with CAL during its first year. Hundreds of BEC experiments have been operated on Earth since the mid-1990s, and a few BEC experiments have even made brief trips to space aboard sounding rockets. But CAL is the first facility of its kind on the space station, wh ere scientists can conduct daily studies of BECs over long periods.

BECs are created in atom traps, or frictionless containers made out of magnetic fields or focused lasers. On Earth, when these traps are shut off, gravity pulls on the ultracold atoms and they can only be studied for fractions of a second. The persistent microgravity of the space station allows scientists to observe individual BECs for five to 10 seconds at a time, with the ability to repeat these measurements for up to six hours per day. As the atom cloud decompresses inside the atom trap, its temperature naturally drops, and the longer the cloud stays in the trap, the colder it gets. This natural phenomenon (that a drop in pressure also means a drop in temperature) is also the reason that a can of spray paint gets cold when the paint is sprayed out: the can's internal pressure is dropping. In microgravity, the BECs can decompress to colder temperatures than any earthbound instrument. Day-to-day operations of CAL require no intervention from the astronauts aboard the station.

In addition to the BECs made from rubidium atoms, the CAL team is working toward making BECs using two different isotopes of potassium atoms.

CAL is currently in a commissioning phase, in which the operations team conducts a long series of tests to fully understand how the CAL facility operates in microgravity.

"There is a globe-spanning team of scientists ready and excited to use this facility," said Kamal Oudrhiri, JPL's mission manager for CAL. "The diverse range of experiments they plan to perform means there are many techniques for manipulating and cooling the atoms that we need to adapt for microgravity, before we turn the instrument over to the principal investigators to begin science operations." The science phase is expected to begin in early September and will last three years.

The Cold Atom Laboratory launched to the space station on May 21, 2018, aboard a Northrop Grumman (formerly Orbital ATK) Cygnus spacecraft from NASA's Wallops Flight Facility in Virginia. Designed and built at JPL, CAL is sponsored by the International Space Station Program at NASA's Johnson Space Center in Houston, and the Space Life and Physical Sciences Research and Applications (SLPSRA) Division of NASA's Human Exploration and Operations Mission Directorate at NASA Headquarters in Washington.

В обитаемый отсек японского модуля МКС попала вода

Москва. 30 июля. INTERFAX.RU - В японском модуле Международной космической станции (МКС) возникли проблемы с системой терморегулирования: в обитаемый отсек проникает вода.

Как пояснил в понедельник "Интерфаксу" источник в ракетно-космической отрасли, японский модуль Kibo располагается в американском сегменте МКС.

"Из-за проблем с внутренней системой терморегулирования модуля происходит утечка чистой воды. Астронавты вынуждены бороться с подтоплением, используя бумажные салфетки и полотенца", - сказал источник.

Источник утечки пока найти пока не удается.

Ранее на американском сегменте МКС вышла из строя одна из систем удаления углекислого газа, астронавты вынуждены на орбите самостоятельно ее ремонтировать. В июне американские астронавты, не сумев подключить магистраль подачи кислорода в шлюзовом отсеке, лишились возможности экстренного выхода в открытый космос с борта станции.
Спойлер
Между тем на МКС и ранее возникали проблемы с системами жизнеобеспечения.

Как сообщалось, на американском сегменте неоднократно фиксировались утечки аммиака, в 2016 году возникла неисправность в блоке обработки технической воды (WPA). Тогда же в американском секторе сломалась система переработки мочи.

Кроме того, в начале 2016 года в американском сегменте МКС произошла крупная поломка, в результате которой вышел из строя контроллер вентилятора мотора на системе удаления углекислого газа CDRA.

В ноябре 2015 года на американском сегменте МКС отказал канал питания, его ремонт потребовал несколько месяцев.

Неоднократно выходил из строя туалет. В 2009 году Центр управления полетами NASA порекомендовал астронавтам повесить на дверь уборной табличку "Не работает". Туалет на станции неоднократно чинили осенью и летом 2008 года.

The Cygnus space freighter was pictured July 15 , 2018, poised for release from the Canadarm2 robotic arm back into Earth orbit ending a 52-day cargo mission at the International Space Station.

A new cancer therapy study is wrapping up aboard the International Space Station this week as an American cargo craft is packed for return to Earth. The Expedition 56 crew also researched how astronauts perceive time and distance in space and back on Earth.
Спойлер
NASA astronaut Serena Auñón-Chancellor has been contributing to pharmaceutical research since the arrival of the AngieX Cancer Therapy experiment July 2 inside the SpaceX Dragon cargo craft. Today, she is examining endothelial cells in space to help determine if they make a good model for targeting the vasculature of tumor cells. Results may improve the design of safer, more effective therapies targeting cancer tumors.

NASA astronaut Ricky Arnold has been loading Dragon with hardware and science samples today ahead of its return to Earth on Friday. Results from the AngieX cancer investigation will also be stowed in Dragon this week for retrieval and analysis on Earth. Robotics controllers will release Dragon from the grips of the Canadarm2 Friday at 12:37 p.m. EDT as Auñón-Chancellor monitors from the Cupola. Less than six hours later, the commercial space freighter will splashdown in the Pacific Ocean off the coast of Baja California.

Another U.S. cargo craft, the Northrop Grumman Cygnus resupply ship released from the space station on July 15, is getting ready to end its stay in space today. The Cygnus was detached from the station's Harmony module in mid-July and has been orbiting Earth for engineering research. It is due to burn up harmlessly over the Pacific Ocean at 5:07 p.m. today.

Alexander Gerst, of the European Space Agency, worked in the Columbus lab module to help doctors understand how an astronaut's perception of time and distance is affected during and after a mission. Results will help mission planners understand how astronauts adapt to space impacting the success and safety of long-term missions.

Вы спрашивали, какие эксперименты проводятся на российском сегменте МКС. Сама жизнь на станции несколько месяцев - это уже интересный эксперимент. Конечно в программу полёта входят много биологических исследований. Над одним из них я сейчас работаю. В ходе эксперимента "Микровир" изучается влияние факторов космического полёта на скорость литического действия бактериофагов на бактерии. Это длительный, но интересный процесс. А что для вас важнее: процесс или результат?

A host of life science studies being returned aboard Dragon looked at cancer therapies, gut microbes, and a variety of other biological phenomena. Samples collected from those studies, including the experiment hardware housing the research, are being transferred from the station and stowed inside the Dragon.

The AngieX Cancer Therapy investigation is completing its run today with NASA astronaut Serena Auñón-Chancellor finalizing research operations inside the Microgravity Science Glovebox. The experiment tested a treatment that targets tumors and the resulting samples are being stowed inside Dragon science freezers.

Rodents studied for the Rodent Research-7 experiment to understand how microbes interact with the gut in space are being returned Friday. Biological samples observed in July for the Micro-11 human reproduction study are also being cold stowed aboard Dragon.

SpaceX technicians will retrieve Dragon loaded with the Earth-bound cargo when it splashes down in the Pacific Ocean Friday afternoon. Once the cargo craft reaches port, personnel from NASA and the Center for the Advancement of Science in Space (CASIS) will collect the research and hardware and distribute it to scientists and engineers for analysis.
