From flames to space chillies and even a spot of storm monitoring: NASA shares pictures of the best scientific experiments on the International Space Station this year
NASA has shared photos of the best scientific experiments aboard the International Space Station (ISS) に 2021.
In an online gallery, the US space agency included images from ‘breakthrough investigations’ ISS crew members worked on this year.
These included growing vegetables in space, engineering cells for research into muscle growth and the use of virtual reality (VR) to learn how humans perceive time in low gravity.
Chillies, lettuce and even the Chinese cabbage pak choi were harvested on the ISS as a part of plant research preparing astronauts for deep space missions.
Technologies were also tested for the upcoming Artemis missions to the Moon, set to take place in 2025, NASAによると.
Crew-1 poses with the chillies they harvested on the ISS before eating them. This plant experiment was the longest in the history of the space station at 137 日々. Studies like this one could help enable viable and sustainable crop production for future missions as humans explore the Moon and Mars
Crew-2 and Crew-3 – two missions to the ISS operated by NASA on SpaceX rockets – harvested crops of chilli peppers. NASA astronaut Kayla Barron can be seen here with a chilli crop
NASA astronaut Michael Hopkins enjoys the aroma of dwarf pak choi growing aboard the space station. The plants were grown for a study that explores space agriculture to sustain astronauts on future missions to the Moon or Mars

The investigation demonstrates passive measures for controlling fluid delivery and uptake in plant growth systems. Reduced gravity creates challenges in providing adequate fluid and nutrition for plant growth. This investigation examines using other physical properties to replace the role of gravity
THE ISS: QUICK FACTS
国際宇宙ステーション (ISS) is a large spacecraft in orbit around Earth. It serves as a home where crews of astronauts and cosmonauts live.
The ISS is a unique science laboratory. NASA is using the space station to learn more about living and working in space. These lessons will make it possible to send humans farther into space than ever before
Several nations worked together to build and use the ISS. It orbits Earth at an average altitude of approximately 250 miles and travels at 17,500 mph.
The ISS, operated by the space agencies of the US, カナダ, ロシア, Japan and Europe, orbits 250 マイル (400 km) 地球上.
に 24 時間, the space station makes 16 orbits of our planet, travelling through 16 sunrises and sunsets.
The space station has been continuously inhabited by humans for 21 年, supporting many scientific breakthroughs.
In one photo from NASA’s gallery, European Space Agency (それ) astronaut Thomas Pesquet – who completed his second stint at the ISS this year – can be seen working on a study called the ‘cardinal muscle investigation’.
This study tests whether such engineered tissues cultured in space could provide a model for studying muscle loss in low gravity, which could help inform the Artemis missions.
In space, the lack of gravity means muscles barely have to work and astronauts have a vigorous exercise routine to stop them from losing large amounts of muscle mass.
Another similar study uses a 3D kidney cell model known as a tissue chip to study the effects of microgravity on formation of microcrystals in kidney tubules.
‘Results could support design of better treatments for conditions such as kidney stones and bone loss for astronauts and osteoporosis for people on Earth,’ NASA says.
ISS astronauts are also making use of their unique vantage point above the Earth for storm and environmental monitoring.
Crew members photograph Earth using digital handheld cameras to record how the planet is changing over time, from human-caused changes like urban growth to natural events such as hurricanes, floods and volcanic eruptions.

One photo shows Hurricane Larry – which passed over Newfoundland in September – as seen from the station’s domed ‘Cupola’ 窓.
Swells from Hurricane Larry caused rough surf and rip current conditions that caused five direct fatalities, an NOAA report published this month said.
8月に, NASA also shared images of Hurricane Ida taken from the ISS, showing the powerful Category 4 hurricane poised menacingly over North America.
NASA astronauts are also using virtual reality (VR) and augmented reality (と) aboard the ISS for some experiments. Unlike virtual reality (VR), AR layers computer-generated images on top of real-life scenes.
They’re using Microsoft’s HoloLens headset to learn more about how humans perceive time in low gravity, as the lower speed of the body’s movement in space may affect time perception.
In this image, Hurricane Larry is pictured out of station’s Cupola window with the solar arrays to the right, which convert solar energy to electrical power
Hurricane Ida is seen in this image taken aboard the International Space Station (ISS). The dangerous hurricane made landfall in Louisiana on August 29, 2021
NASA astronaut Shane Kimbrough carries the second ISS roll out solar array (iROSA) toward the space station’s Port-6 truss structure where he and fellow spacewalker Pesquet would go on to install it
‘Crew members wear a head-mounted VR display, listen to instructions, and use a finger trackball connected to a laptop to respond, NASA says.
‘They take tests once a month during flight, as well as before launching to space and after returning to Earth, to evaluate adaptive changes.’
HoloLens is also being put to use as part of the Cold Atom Lab (CAL), a ISS quantum science facility that hosts experiments exploring properties of atoms.
7月に, the CAL team successfully demonstrated using an AR headset to assist astronauts with upgrade activities.
NASA also captured an image of a hot flame of nitrogen-diluted propane created aboard the space station.
It was formed as a part of the Cool Flames Investigation with Gases study, which aims to better understand flames that burn at extremely low temperatures.
Without buoyancy, soot remains in the flame longer and forms large clusters.

The ISS, which launched back in 1998, has had a busy year – multiple Soyuz spacecrafts carried astronauts to and from station, while the Crew 2, and Crew 3 missions supported hundreds of experiments aboard the orbiting laboratory.
It also averted a disaster in July when thrusters of a newly-arrived Russian research module, called Nauka, inadvertently fired a few hours after it docked.
11月 11, NASA launched Crew 3, the third fully-fledged ‘operational’ 乗組員NASAとスペースXはISSに飛んでいます. 乗組員 successfully reached the ISS about a day after the launch.
クルー 3 marked the fourth crew NASA has launched to orbit aboard a SpaceX vehicle in 17 月, SpaceXとの官民パートナーシップに基づいて構築, で設立された民間企業 2002 イーロン・マスク.
