Crew Sets Up New Science During Ongoing Bone Research













ISS - Expedition 62 Mission patch.

March 10, 2020

The Expedition 62 crew started unloading and activating new science experiments, which were delivered Monday aboard the SpaceX Dragon resupply ship.

NASA astronauts Andrew Morgan and Jessica Meir opened Dragon’s hatch shortly after its capture and installation on Monday. The duo quickly retrieved critical research samples and installed science hardware, setting up operations aboard the International Space Station.

Mice are living on the station now after their ride to space aboard Dragon. Morgan placed the rodents in specialized habitats for a JAXA (Japan Aerospace Exploration Agency) investigation exploring how microgravity affects genetic expression. Observations will give doctors insights into the how human body will adapt to longer missions to the Moon, Mars and beyond.

Meir collected a science freezer and commercial research hardware from inside Dragon and began setting up the gear throughout the orbital lab. In the afternoon, she got back to work on ongoing bone research tending to bone cells being observed to understand Earth ailments such as osteoporosis.

Bennu’s Boulders Shine as Beacons for NASA’s OSIRIS-REx












NASA - OSIRIS-REx Mission patch.

March 10, 2020

This summer, the OSIRIS-REx spacecraft will undertake NASA’s first-ever attempt to touch the surface of an asteroid, collect a sample of it, and safely back away. But since arriving at asteroid Bennu over a year ago, the mission team has been tackling an unexpected challenge: how to accomplish this feat at an asteroid whose surface is blanketed in building-sized boulders.

Using these hazardous boulders as signposts, the mission team developed a new precision navigation method to overcome the challenge.

How OSIRIS-REx will Steer Itself to Sample an Asteroid

Video above: In late August, the OSIRIS-REx spacecraft will navigate to asteroid Bennu’s surface for its first sample collection attempt. To do this, it will use an onboard image software known as Natural Feature Tracking (NFT) — a form of optical navigation that is completely autonomous. Video Credits: NASA's Goddard Space Flight Center/Scientific Visualization Studio.

The OSIRIS-REx team had originally planned to use a LIDAR system to navigate to Bennu’s surface during the Touch-And-Go (TAG) sample collection event. LIDAR is similar to radar, but it uses laser pulses rather than radio waves to measure distance. The OSIRIS-REx Guidance, Navigation, and Control (GNC) LIDAR is designed to navigate the spacecraft to a relatively hazard-free surface. The mission had originally envisioned a touchdown site 164 ft (50 meters) in diameter, but the largest safe areas on Bennu are much smaller. The biggest site is just 52 ft (16 m) wide, or roughly 10% of the safe area envisioned. The team realized that they needed a more precise navigation technique that would allow the spacecraft to accurately target very small sites while dodging potential hazards.

In the face of this challenge, the OSIRIS-REx team switched to a new navigation method called Natural Feature Tracking (NFT). NFT provides more extensive navigation capabilities than LIDAR, and is key for executing what the team is calling “Bullseye TAG,” which delivers the spacecraft to the much smaller sampling area. As an optical navigation technique, it requires the creation of a high-resolution image catalog onboard the spacecraft.

Earlier this year, the spacecraft made reconnaissance passes over the mission’s primary and backup sample collection sites, designated Nightingale and Osprey, flying as close as 0.4 miles (625 m) over the surface. During these flyovers, the spacecraft collected images from different angles and lighting conditions to complete the NFT image catalog. The team uses this catalog to identify boulders and craters unique to the sample site region, and will upload this information to the spacecraft before the sample collection event. NFT autonomously guides the spacecraft to Bennu’s surface by comparing the onboard image catalog with the real-time navigation images taken during descent. As the spacecraft descends to the surface, NFT updates its predicted point of contact depending on the spacecraft’s position in relation to the landmarks.


Image above: During the sample collection event, Natural Feature Tracking (NFT) will guide NASA’s OSIRIS-REx spacecraft to asteroid Bennu’s surface. The spacecraft takes real-time images of the asteroid’s surface features as it descends, and then compares these images with an onboard image catalog. The spacecraft then uses these geographical markers to orient itself and accurately target the touchdown site. Image Credits: NASA/Goddard/University of Arizona.

On the ground, team members created “hazard maps” for both the Nightingale and Osprey sites to document all of the surface features that could potentially harm the spacecraft, like large rocks or steep slopes. The team used the image catalog in conjunction with data from the OSIRIS-REx Laser Altimeter (OLA) to create 3D maps that closely model Bennu’s topography. As part of NFT, these maps document boulder heights and crater depths, and guide the spacecraft away from potential hazards while targeting a very small site. During descent, if the spacecraft predicts it will touch unsafe terrain, it will autonomously wave-off and back away from the surface. However, if it sees that the area is free of hazards, it will continue to descend and attempt to collect a sample.

NFT will be used in April to navigate the spacecraft during its first sample collection rehearsal. The operations team performed preliminary testing during the Orbital B mission phase in late 2019, and the results demonstrated that NFT works in real-life conditions as designed. NFT will also be used for navigation during the second rehearsal planned for June.

OSIRIS-REx’s first sample collection attempt is scheduled for late August. The spacecraft will depart Bennu in 2021 and is scheduled to deliver the sample to Earth in September 2023.

NASA’s Goddard Space Flight Center in Greenbelt, Maryland, provides overall mission management, systems engineering, and the safety and mission assurance for OSIRIS-REx. Dante Lauretta of the University of Arizona, Tucson, is the principal investigator, and the University of Arizona also leads the science team and the mission’s science observation planning and data processing. Lockheed Martin Space in Denver built the spacecraft and provides flight operations. Goddard and KinetX Aerospace are responsible for navigating the OSIRIS-REx spacecraft. OSIRIS-REx is the third mission in NASA’s New Frontiers Program, which is managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama, for the agency’s Science Mission Directorate in Washington.

Astronomers Use Slime Mould to Map the Universe’s Largest Structures













ESA - Hubble Space Telescope logo.

10 March 2020

Map of the Cosmic Web Generated from Slime Mould Algorithm

The behaviour of one of nature’s humblest creatures and archival data from the NASA/ESA Hubble Space Telescope are helping astronomers probe the largest structures in the Universe.

The single-cell organism known as slime mould (Physarum polycephalum) builds complex web-like filamentary networks in search of food, always finding near-optimal pathways to connect different locations.

In shaping the Universe, gravity builds a vast cobweb-like structure of filaments tying galaxies and clusters of galaxies together along invisible bridges of gas and dark matter hundreds of millions of light-years long. There is an uncanny resemblance between the two networks, one crafted by biological evolution, the other by the primordial force of gravity.

The cosmic web is the large-scale backbone of the cosmos, consisting primarily of dark matter and laced with gas, upon which galaxies are built. Even though dark matter cannot be seen, it makes up the bulk of the Universe’s material. Astronomers have had a difficult time finding these elusive strands, because the gas within them is too dim to be detected.

The Cosmic Web (Artist’s Impression)

The existence of a web-like structure to the Universe was first hinted at in galaxy surveys in the 1980s. Since those studies, the grand scale of this filamentary structure has been revealed by subsequent sky surveys. The filaments form the boundaries between large voids in the Universe. Now a team of researchers has turned to slime mould to help them build a map of the filaments in the local Universe (within 100 million light-years of Earth) and find the gas within them.

They designed a computer algorithm, inspired by the behaviour of slime mould, and tested it against a computer simulation of the growth of dark matter filaments in the Universe. A computer algorithm is essentially a recipe that tells a computer precisely what steps to take to solve a problem.

The researchers then applied the slime mould algorithm to data containing the locations of over 37 000 galaxies mapped by the Sloan Digital Sky Survey. The algorithm produced a three-dimensional map of the underlying cosmic web structure.

They then analysed the light from 350 faraway quasars catalogued in the Hubble Spectroscopic Legacy Archive. These distant cosmic flashlights are the brilliant black-hole-powered cores of active galaxies, whose light shines across space and through the foreground cosmic web. Imprinted on that light was the telltale signature of otherwise invisible hydrogen gas that the team analysed at specific points along the filaments. These target locations are far from the galaxies, which allowed the research team to link the gas to the Universe’s large-scale structure.

Zooming Through the Cosmic Web (Artist’s Impression)

“It’s really fascinating that one of the simplest forms of life actually enables insights into the very largest-scale structures in the Universe,” said lead researcher Joseph Burchett of the University of California (UC), U.S.A. “By using the slime mould simulation to find the location of the cosmic web filaments, including those far from galaxies, we could then use the Hubble Space Telescope’s archival data to detect and determine the density of the cool gas on the very outskirts of those invisible filaments. Scientists have detected signatures of this gas for over half a century, and we have now proven the theoretical expectation that this gas comprises the cosmic web.”

The survey further validates research that indicates intergalactic gas is organised into filaments and also reveals how far away gas is detected from the galaxies. Team members were surprised to find gas associated with the cosmic web filaments more than 10 million light-years away from the galaxies.

But that wasn’t the only surprise. They also discovered that the ultraviolet signature of the gas gets stronger in the filaments’ denser regions, but then disappears. “We think this discovery is telling us about the violent interactions that galaxies have in dense pockets of the intergalactic medium, where the gas becomes too hot to detect,” Burchett said.

The researchers turned to slime mould simulations when they were searching for a way to visualise the theorised connection between the cosmic web structure and the cool gas, detected in previous Hubble spectroscopic studies.

Then team member Oskar Elek, a computer scientist at UC Santa Cruz, discovered online the work of Sage Jenson, a Berlin-based media artist. Among Jenson’s works were mesmerizing artistic visualisations showing the growth of a slime mould’s tentacle-like network of structures moving from one food source to another. Jenson’s art was based on scientific work from 2010 by Jeff Jones of the University of the West of England in Bristol, which detailed an algorithm for simulating the growth of slime mould.

 Hubble Space Telescope (HST)

The research team was inspired by how the slime mould builds complex filaments to capture new food, and how this mapping could be applied to how gravity shapes the Universe, as the cosmic web constructs the strands between galaxies and galaxy clusters. Based on the simulation outlined in Jones’s paper, Elek developed a three-dimensional computer model of the buildup of slime mould to estimate the location of the cosmic web’s filamentary structure.

This analysis of the cosmic web in the local Universe also dovetails with observations published last autumn in the journal Science of the Universe’s filamentary structure much farther away, about 12 billion light-years from Earth, near the Universe’s beginning. In that study, astronomers analysed the energetic light from a young galaxy cluster illuminating the filaments of hydrogen gas connecting it.

The team’s paper will appear in the Astrophysical Journal Letters:

Plant Growth on the International Space Station has Global Impacts on Earth













ISS - Expedition 5 Mission patch.

March 9, 2020

Understanding the effects of gravity on plant life is essential in preparing for human exploration beyond low-Earth orbit. The ability to produce high-energy, low-mass food sources during spaceflight will enable the maintenance of crew health during long-duration missions while having a reduced impact on resources necessary for long-distance travel.


Image above: Astronaut Peggy Whitson with the ADVASC soybean plant growth experiment during Expedition 5. Image Credit: NASA.

The Advanced Astroculture™ (ADVASC) investigation, led by Weijia Zhou, Ph.D., formerly of the Wisconsin Center for Space Automation and Robotics, University of Wisconsin-Madison, explored the benefits of using microgravity to create custom crops that can withstand the inhospitable climates of space, can resist pestilence, and will need less volume in which to grow. ADVASC was performed over several ISS expeditions where it grew two generations of Arabidopsis thaliana (i.e., a rapidly growing, flowering plant in the mustard family that has been grown on many space missions), and soybean plants from seed to seed in space using the ADVASC payload––an autonomously operated plant growth unit. The ability to grow plants from seeds through several generations has proven to be challenging in space and is critical in developing hardware and operational concepts to take human explorers farther beyond low-Earth orbit.

While serving as a unique plant-growth chamber, the ADVASC hardware design has also contributed to national security, cancer-fighting pharmaceuticals and educational tools for students. ADVASC’s novel air scrubber was designed to remove ethylene from the chamber atmosphere to increase longevity of the produce. Ethylene––a naturally occurring, odorless, colorless gas given off by plants––hastens the ripening of fruits and the aging of flowers, thus encouraging decay. In closed growing environments such as a spacecraft or terrestrial greenhouse, ethylene builds up quickly. As a result, plants mature too fast. Removing ethylene, therefore, is important to preserving crops not just in space, but also on Earth, where grocers and florists have an interest in longer product shelf life.

The ethylene-reduction device, also called the ethylene “scrubber,” draws air through tubes that are coated in thin layers of titanium dioxide. The insides of the tubes are exposed to ultraviolet light, which creates a simple chemical reaction that converts the ethylene into trace amounts of water and carbon dioxide, both of which are actually good for plants.

KES Science & Technology Inc., a Georgia-based company specializing in sustaining perishable foods, licensed the ethylene-scrubbing technology from the University of Wisconsin. KES partnered with Akida Holdings, of Jacksonville, Florida, which now markets the NASA-developed technology as Airocide. According to the company, Airocide is the only air purifier that completely destroys airborne bacteria, mold, fungi, mycotoxins, viruses, volatile organic compounds such as ethylene, and odors. The device has no filters that need changing and produces no harmful by-products, such as the ozone created by some filtration systems.

Food preservation customers include supermarkets, produce distribution facilities, food processing plants, wineries, distilleries, restaurants and large floral shops. Reeves Floral, an Airocide user, reported 92% reduction in airborne mold and a 58% drop in airborne bacteria levels after only 24 hours of operation in its floral storage warehouse. These units in walk-in coolers can preserve freshness of produce during storage and transport, increase safety in food preparation areas, kill bacterial contaminants in flowers, and protect against spoilage and contaminants.

Units also have been deployed to India and the Gulf Cooperation Council, which includes the countries of Bahrain, Kuwait, Qatar, Oman, Saudi Arabia, and the United Arab Emirates. In these areas, where refrigerated trucks carry groceries from rural farmland to towns miles away, the unit preserves freshness and prevents food spoilage.

The units also operate in doctors’ clinics, operating rooms, neonatal wards, and waiting areas, an often overlooked location rife with germs and bacteria such as respiratory influenza or mycobacterium tuberculosis, and which are frequented by people with compromised immune systems. Units made operating rooms safer for all inhabitants by removing harmful bacteria such as methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus, and the fungi Penicillium and Aspergillus. In addition to eliminating virtually all known airborne germs and diseases, the technology reduces the burden on high-efficiency particulate air filters and laminar flow environments.

ISS Benefits for Humanity: From NASA to Napa

Adaptions for use in everyday living environments include eliminating mold, mildew, germs and unwanted odors in hotel rooms and offices, where illnesses caused by airborne organisms can lower productivity. Airocide even offers a consumer line that makes the same technology used on the space station available in homes to help eliminate bacteria, mold and fungi as well as allergens such as dust and dander, and potentially harmful particulate matter.

Lunar Gateway: Earth’s guard post against asteroids?













International - Lunar Gateway patch.

March 9, 2020

Gateway

Humankind’s next space outpost, the lunar Gateway, will serve as a staging point to reach the surface of the Moon. A new ESA-backed study is considering whether it could also be used as a deployment point for planetary defence missions, to intercept asteroids approaching dangerously close to Earth.

Set for assembly over the course of this decade, the Gateway will be placed in a highly elongated, or ‘eccentric’ week-long orbit around the Moon, passing a minimum 3000 km from the lunar surface and 70 000 km at its furthest away. Crewed missions will require much less energy to rendezvous with the Gateway than to fly direct to the surface of the Moon, and could then venture down using Gateway-based landers.

Gateway and Moon

But the Gateway could also support operations into deep space – including spacecraft for planetary defence, to deflect the orbital paths of incoming asteroids.

The concept might sound like science fiction, but Earth’s first planetary defence missions are already in active preparation. NASA’s Double Asteroid Redirect Test (DART) spacecraft, due to launch next year, will impact the smaller of the Didymos asteroid pair, in orbit between Earth and Mars, in a bid to shift its orbit. In 2026 ESA’s Hera spacecraft will perform a close-up survey of the asteroid post-impact.

NASA's DART impacting asteroid

The DART and Hera missions, known jointly as the Asteroid Impact and Deflection Assessment (AIDA) collaboration represent an experimental trial-run on a distant body that poses no threat to Earth. Once proven, the deflection technique could be used for real on asteroids coming dangerously close – but a rapid reaction time would be crucial for maximum effectiveness.

Accordingly ESA is funding a new study by Politechnico di Milano to analyse options for using the Gateway to park planetary defence spacecraft in readiness to intercept incoming asteroids. These spacecraft would be able to depart the Gateway with much lower energies compared with departing from Earth itself.

An exploration and science outpost in orbit around the Moon

Other OSIP-submitted research ideas selected for funding in January 2020 include:

- New ways of building satellites might be creating a new type of space debris: the latest carbon fibre reinforced plastics, when broken apart, could be giving rise to vast amounts of tiny fragments of carbon fibres. These are not represented in current debris models, so a dedicated model needs to be made.

- Air-filled integrated waveguides could enable the design of low-cost, high performance antennas for the coming wave of satellite constellations.

- The autonomy of embedded devices aboard satellites could be boosted using AI-based hardware accelerators.

- With nanomaterials used increasingly for biomedical applications, investigation is needed into how weightlessness influences their effects within biological systems.

There are many more challenges currently live on OSIP – take a look for yourself: https://ideas.esa.int/servlet/hype/IMT?userAction=BrowseCurrentUser&templateName=MenuItem

Here’s some of the research arriving at station:

New Facility Outside the Space Station

The Bartolomeo facility, created by ESA (European Space Agency) and Airbus, attaches to the exterior of the European Columbus Module. Designed to provide new scientific opportunities on the outside of the space station for commercial and institutional users, the facility offers unobstructed views both toward Earth and into space. Potential applications include Earth observation, robotics, material science and astrophysics.

Studying the Human Intestine On a Chip

Organ-Chips as a Platform for Studying Effects of Space on Human Enteric Physiology (Gut on Chip) examines the effect of microgravity and other space-related stress factors on biotechnology company Emulate’s human innervated Intestine-Chip (hiIC). This Organ-Chip device enables the study of organ physiology and diseases in a laboratory setting. It allows for automated maintenance, including imaging, sampling, and storage on orbit and data downlink for molecular analysis on Earth.

Growing Human Heart Cells

Generation of Cardiomyocytes From Human Induced Pluripotent Stem Cell-derived Cardiac Progenitors Expanded in Microgravity (MVP Cell-03) examines whether microgravity increases the production of heart cells from human-induced pluripotent stem cells (hiPSCs). The investigation induces stem cells to generate heart precursor cells and cultures those cells on the space station to analyze and compare with cultures grown on Earth.

Space Station 20th – Women and the Space Station











20 Years of the International Space Station (ISS) patch.

March 8, 2020

Celebrating International Women’s Day and Women’s History Month

International Space Station (ISS). Animation Credit: NASA

“A bird cannot fly with one wing only. Human space flight cannot develop any further without the active participation of women.” – Valentina Tereshkova

“If we want scientists and engineers in the future, we should be cultivating the girls as much as the boys.” – Sally Ride

“International cooperation is very necessary. Chinese have a saying, ‘When all the people collect the wood, you will make a great fire.’” – Liu Yang

International Space Station 20th Banner

As of March 2020, 65 women have flown in space. Of these, 38 have visited the International Space Station (ISS) as long-duration expedition crewmembers, as visitors on Space Shuttle assembly flights or as Space Flight Participants on short-duration Soyuz missions. It is fitting to recognize the significant accomplishments of these women as well as the pioneering women who preceded them into space. This article cannot recognize all the great contributions by women to make ISS the unique laboratory in space and only strives to capture significant firsts. Many other women contributed to the assembly of the station and the research being conducted aboard on a daily basis. These include not only the astronauts who flew the daring missions but also the many women on the ground who as center directors, managers, flight directors and in many other roles continue the exploration of space, as NASA endeavors to land the first woman and the next man on the Moon and possibly send the first crews to Mars in the coming decades.

Soviet cosmonaut Valentina V. Tereshkova made history on June 16, 1963, when she launched aboard Vostok 6 as the first woman in space. Soviet plans to launch other female cosmonauts in the 1960s never materialized and nearly 20 years passed before another woman flew in space. In January 1978, NASA announced the selection of 35 new astronauts including six women for the Space Shuttle program. In response, the Soviet Union secretly selected a group of nine women cosmonauts in 1980. On Aug. 19, 1982, one of those, Svetlana Y. Savitskaya, launched with her two crewmates aboard Soyuz T-7 to spend a week aboard the Salyut-7 space station. The next day they joined the two long-duration resident crewmembers aboard, marking the first time a space station hosted a mixed-gender crew. Ten months later, astronaut Sally K. Ride made history on June 18, 1983, becoming the first American woman in space, spending seven days aboard the Space Shuttle Challenger during the STS-7 mission.

Above: Tereshkova just before boarding her Vostok 6 capsule. Bellow: Ride aboard the Space Shuttle Challenger during the STS-7 mission.

Savitskaya made history again on July 25, 1984, as the first woman to participate in a spacewalk or Extra-Vehicular Activity (EVA) during her second flight to Salyut 7. Less than three months later, on Oct. 11, Kathryn D. Sullivan completed the first EVA by an American woman from the Space Shuttle Challenger during the STS-41G mission. With Ride as one of Sullivan’s crewmates, the flight marked the first time that two women flew on the same mission.

Above: Savitskaya during her EVA outside Salyut-7. Bellow: Sullivan (at left) and Ride aboard Space Shuttle Challenger during the STS-41G mission.

The honor of the first woman to complete a long-duration mission in space belongs to Russian cosmonaut Elena V. Kondakova. She launched aboard the Soyuz TM20 spacecraft on Oct. 3, 1994, and spent 169 days aboard the Mir space station as part of Expedition 17, returning to Earth on March 22, 1995. The first American woman to complete a long-duration mission, Shannon W. Lucid launched on March 22, 1996, aboard Space Shuttle Atlantis. The second astronaut to fly as part of the Shuttle-Mir Program she spent 188 days aboard Mir as part of Expeditions 21 and 22, returning to Earth with STS-79 on Sep. 26.

Above: Kondakova (second from right) aboard Mir during the handover between
Expedition 16 and 17. Bellow: Lucid (at left) with her Mir Expedition 21 crewmates.

As on-orbit assembly of ISS commenced in 1998, women were literally on board from the very beginning. As the first woman to reach ISS, Nancy J. Currie participated in the first assembly mission, STS-88 in December 1998, using the Shuttle’s robotic arm to precisely join the American Unity Node 1 module to the Russian-built Zarya module, launched three weeks earlier.

Above: Currie (in front at right), the first woman to reach ISS with her STS-88 crewmates. Bellow: Currie at work in the Zarya module.

The second Space Shuttle assembly mission, STS-96 in May 1999, included three women on the crew – Tamara E. “Tammy” Jernigan, Ellen L. Ochoa and Julie Payette. Jernigan became the first woman to participate in an EVA at ISS to install crane equipment for future assembly tasks, with Ochoa as the robotic arm operator. Payette became the first Canadian of any gender to visit ISS, and became the first Canadian to make a second visit to ISS during STS-127 in 2009.

Above: STS-96 crew in the Unity Node 1 module, with Jernigan and Payette in the top row and Ochoa at bottom right. Middle: Jernigan during the STS-96 EVA. Bellow: Payette in the Unity Node 1 module.

Astronaut Pamela A. Melroy was the first woman to serve as Pilot on a Shuttle flight to ISS, STS-92 in October 2000, the mission that added the Z1 truss, control moment gyros and a Pressurized Mating Adaptor to the developing station. She returned to ISS as Pilot of STS-112 in October 2002 and as Commander of STS-120 in October 2007. Astronaut Susan J. Helms holds several distinctions for women. As a member of Expedition 2, she became the first woman to complete a long-duration mission on ISS, a 167-day flight between March and August of 2001. She had previously flown to ISS during STS-101, making her the first woman to visit the station twice. Helms was the first woman with a military background to visit ISS, having graduated in the U.S. Air Force Academy’s first woman-inclusive class of 1980. She co-holds the record for the longest EVA to date, 8 hours and 56 minutes, completed with her Expedition 2 crewmate James S. Voss.

Above: STS-92 Pilot Melroy shortly after reaching orbit. Bellow: Expedition 2 Commander Yuri V. Usachev (at left) coaxing a reluctant Flight Engineer Helms to leave ISS at the end of their mission.

Eileen M. Collins had already made history twice before, first in 1995 as the first female Pilot of a Space Shuttle mission and again in 1999 as the first woman Shuttle Commander. In 2005, Collins became the first woman to command a Shuttle mission to ISS, the Return to Flight STS-114 mission, the first after the Columbia accident two years previously. Heidemarie M. “Heidi” Stefanyshyn-Piper was the first woman to conduct an EVA from the station’s Quest Joint Airlock Module on Sep. 12, 2006, during the STS-115 mission that installed the P3/P4 truss segment on ISS.

Peggy A. Whitson became the first woman Commander of ISS during Expedition 16 in 2007, her second long-duration mission to the station. Expedition 16 was notable for the addition to ISS of the Harmony Node 2 module, the European Space Agency’s (ESA) Columbus research module, the first of the Japan Aerospace Exploration Agency (JAXA) elements and the arrival of the first of ESA’s Automated Transfer Vehicle (ATV) cargo resupply vehicles named Jules Verne. As noted above, Melroy commanded STS-120, the October 2007 mission that brought Columbus to ISS, marking the first and only time that Commanders of both ISS and the visiting Space Shuttle were women. In 2017, during Expedition 51 Whitson became the first woman to command ISS for a second time. As of March 2020, Whitson holds the record for most cumulative spaceflight time for a woman as well as for any American astronaut. Over the course of three long-duration missions aboard ISS, she spent a total of 639 days or about 1.75 years in space. She also holds the record for the most EVA time for a woman – over her three missions, she spent 60 hours and 21 minutes outside the station in the course of 10 EVAs.

Between May 16 and 23, 2010, for the first time four women were aboard ISS at one time. Expedition 23 Flight Engineer Tracy E. Caldwell Dyson had been living and working since April when STS-131 arrived, with Dorothy M. “Dottie” Metcalf-Lindenburger, Stephanie D. Wilson and Naoko Yamazaki as part of the Shuttle crew. The mission brought four new research facilities to the station. Three weeks after the Shuttle’s departure, Caldwell Dyson and her crewmates welcomed a new trio of long-duration crewmembers including Shannon Walker, making Expedition 24 the first to include two women. The next two-woman expedition took place between November 2014 and March 2015 – Expedition 42 included Elena O. Serova, the first Russian woman to make a long-duration flight aboard ISS, and Samantha Cristoforetti from Italy, the first female ESA astronaut on a long-duration mission.

Expeditions including two women have recently become more common. During Expedition 57, Serena M. Auñón-Chancellor and Anne C. McClain overlapped by about three weeks in December 2018, between March and June 2019 McClain and Christina Hammock Koch were aboard as part of Expedition 59, and Jessica U. Meir joined Koch in September of that year during Expedition 61. Koch returned to Earth in February 2020, completing a flight of 329 days, the longest to date by a woman.

The Expedition 61 crew conducted a record nine EVAs between October 2019 and January 2020. Koch and Meir made history on Oct. 18 when they floated outside ISS to carry out the first all-woman EVA, one of several spacewalks to replace the station’s batteries. The capsule communicator (Capcom), the astronaut in Mission Control who communicates with the astronauts in space, for this historic EVA was three-time Space Shuttle veteran Stephanie Wilson (who as noted above took part in the first four-woman gathering on ISS), assisted by space station veteran Mark T. Vande Hei. "As much as it's worth celebrating the first spacewalk with an all-female team, I think many of us are looking forward to it just being normal," astronaut Caldwell Dyson said during live coverage of the spacewalk. As if to prove her point, Koch and Meir conducted two more all-woman EVAs in January 2020.

The story of women in space would not be complete without mention of the two women from the People’s Republic of China who have flown in space. China’s first female astronaut, Yiu Yang, launched on June 16, 2012, aboard the Shenzhou-9 spacecraft with her two crewmates, docking with the Tiangong-1 space station two days later. The trio returned to Earth after a 13-day mission. One year later, on June 11, 2013, Wang Yaping and her two crewmates launched aboard Shenzhou 10 for a 14-day visit to Tiangong-1. Wang conducted science experiments and taught a live physics lessons to school children from aboard the station.
