Microgravity had no immediate effect on a person’s ability to perceive the height of an object, indicating that astronauts can safely perform tasks that rely on accurate and precise height judgments soon after arrival in space.
We use the height and width of objects around us to complete tasks such as reaching for objects and deciding whether we can fit through an opening. VECTION, an investigation from the Canadian Space Agency, examined the effect of microgravity on an astronaut’s visual perception and how that ability may adapt during flight or upon return to Earth. Researchers conclude there is no need for countermeasures but suggest that space travelers be made aware of late-emerging and potentially long-lasting changes in the ability to perceive object height.
Canadian Space Agency astronaut David Saint-Jacques conducts a session for the VECTION experiment. NASA/Anne McClain Analysis of the genomes of five new species of bacteria found on the International Space Station identified specific adaptations to space, including the development of increased antibiotic resistance and a greater potential for causing diseases. The genes that facilitate these adaptations could serve as potential targets for drugs, helping to protect crew health on future missions.
Microbial Tracking-2 monitored viruses, bacteria, and fungi on the space station to catalog and characterize any with the potential to cause disease. Understanding the mechanisms behind adaptations to space could advance development of ways to protect crew member health as well as spacecraft and equipment on future missions. Microbial adaptations also have potential applications in biotechnology, such as engineering more resilient organisms for use in space and extraterrestrial environments.

NASA/Jack Fischer When NASA’s Airborne Lightning Observatory for Fly’s Eye and the space station’s ASIM instrument briefly passed over the same geographic area, the airborne instrument detected terrestrial gamma‐ray flashes (TGFs) that were not detected by ASIM. TGFs are short bursts of gamma‐rays produced by lightning in thunderclouds. This result suggests that a significant number of TGFs are too weak to be observed from space and that the percentage of lightning associated with these phenomena may be higher than previously thought.
ASIM, an investigation from the European Space Agency, studies high-altitude lightning in thunderstorms and the role it plays in Earth’s atmosphere and climate. Results could help scientists develop better atmospheric models to guide weather and climate prediction and response. The airborne instrument took measurements at an altitude of about 12 miles and ASIM at approximately 260 miles above Earth’s surface.

NASA has selected four new crew members to participate in the final simulated mission to Mars in 2024 inside the agency’s Human Exploration Research Analog. From left are Kristen Magas, Anderson Wilder, Obaid Alsuwaidi, and Tiffany Snyder.Credit: C7M4 Crew NASA selected a crew of four research volunteers to participate in its last simulated mission to Mars in 2024 within a habitat at the agency’s Johnson Space Center in Houston.
Obaid Alsuwaidi, Kristen Magas, Tiffany Snyder, and Anderson Wilder will step into the 650-square-foot HERA (Human Exploration Research Analog) facility on Friday, Nov. 1. Once inside, the team will live and work like astronauts for 45 days. The crew will exit the facility on Monday, Dec. 16, after simulating their return to Earth. Jordan Hundley and Robert Wilson also were named as alternate crew members.
Scientists use HERA studies to examine how crew members adapt to isolation, confinement, and remote conditions before NASA sends astronauts on deep space missions to the Moon, Mars, and beyond. The studies provide data about human health and performance in an enclosed environment over time with crews facing different challenges and tasks.
The four volunteers will carry out scientific research and operational tasks throughout their simulated mission, including raising shrimp, growing vegetables, and “walking” on the surface of Mars using virtual reality. They will also experience communication delays lasting up to five minutes as they “near” Mars, allowing researchers to see how crews may respond to the type of delays astronauts will encounter in deep space. Astronauts traveling to the Red Planet may encounter one-way communication delays lasting as long as 20 minutes.
As with the previous HERA missions, crew members will conduct 18 human health studies during the mission through NASA’s Human Research Program. Collectively, the work helps scientists understand how a spaceflight-like environment contributes to the physiological, behavioral, and psychological health of crew members. Insights gleaned from the studies will allow researchers to develop and test strategies aimed at helping astronauts overcome obstacles on deep space missions.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s C-130 Hercules is prepared for departure from NASA’s Wallops Flight Facility in Virginia, on October 15, 2024, for a cargo transport mission to India. The C-130 is supporting the NASA-ISRO Synthetic Aperture Radar (NISAR) mission.NASA/Madison Griffin NASA’s globetrotting C-130 Hercules team is carrying out a cargo transport mission to Bengaluru, India, in support of the NASA-ISRO Synthetic Aperture Radar (NISAR) mission.
The C-130 departed from NASA’s Wallops Flight Facility in Virginia, Tuesday, Oct. 15, to embark on the multi-leg, multi-day journey. The flight path will take the aircraft coast to coast within the United States, across the Pacific Ocean with planned island stops, and finally to its destination in India. The goal: safely deliver NISAR’s radar antennae reflector, one of NASA’s contributions to the mission, for integration on the spacecraft. NISAR is a joint mission between NASA and ISRO (Indian Space Research Organisation).
The cargo transport mission will encompass approximately 24,500 nautical miles and nearly 80 hours of flight time for the C-130 and crew. The flight plan includes strategic stops and rest days to service the aircraft and reduce crew fatigue from long-haul segments of the flight and multiple time zone changes.
The flight crew inspects the aircraft prior to departure from NASA Wallops.NASA/Madison Griffin The C-130’s cargo compartment has plenty of space to hold the more than 2,800-pound payload containing the radar antennae reflector once retrieved from California.NASA/Madison Griffin The first stop for the C-130 was March Air Reserve Base located in Riverside County, California, to retrieve the radar antennae reflector from NASA’s Jet Propulsion Laboratory in Southern California. Additional stops during the mission include Hickman Air Force Base, Hawaii; Andersen Air Force Base, Guam; Clark Air Base, Philippines; and Hindustan Aeronautics Limited Airport in Bengaluru, India.
This is the C-130 and crew’s third cargo transport to India in support of the NISAR mission, with prior flights in July 2023 and March 2024.

Due to launch in the early 2030s, NASA’s DAVINCI mission will investigate whether Venus — a sweltering world wrapped in an atmosphere of noxious gases — once had oceans and continents like Earth.
Consisting of a flyby spacecraft and descent probe, DAVINCI will focus on a mountainous region called Alpha Regio, a possible ancient continent. Though a handful of international spacecraft plunged through Venus’ atmosphere between 1970 and 1985, DAVINCI’s probe will be the first to capture images of this intriguing terrain ever taken from below Venus’ thick and opaque clouds.
But how does a team prepare for a mission to a planet that hasn’t seen an atmospheric probe in nearly 50 years, and that tends to crush or melt its spacecraft visitors?
Scientists leading the DAVINCI mission started by using modern data-analysis techniques to pore over decades-old data from previous Venus missions. Their goal is to arrive at our neighboring planet with as much detail as possible. This will allow scientists to most effectively use the probe’s descent time to collect new information that can help answer longstanding questions about Venus’ evolutionary path and why it diverged drastically from Earth’s.
On the left, a new and more detailed view of Venus’ Alpha Regio region developed by scientists on NASA’s DAVINCI mission to Venus, due to launch in the early 2030s. On the right is a less detailed map created using radar altimeter data collected by NASA’s Magellan spacecraft in the early 1990s. The colors on the maps depict topography, with dark blues identifying low elevations and browns identifying high elevations. To make the map on the left, the DAVINCI science team re-analyzed Magellan data and supplemented it with radar data collected on three occasions from the Arecibo Observatory in Puerto Rico, and used machine vision computer models to scrutinize the data and fill in gaps in information. The red ellipses on each image mark the area DAVINCI’s probe will descend over as it collects data on its way toward the surface. Jim Garvin/NASA’s Goddard Space Flight Center Between 1990 and 1994, NASA’s Magellan spacecraft used radar imaging and altimetry to map the topography of Alpha Regio from Venus’ orbit. Recently, NASA’s DAVINICI’s team sought more detail from these maps, so scientists applied new techniques to analyze Magellan’s radar altimeter data. They then supplemented this data with radar images taken on three occasions from the former Arecibo Observatory in Puerto Rico and used machine vision computer models to scrutinize the data and fill in gaps in information at new scales (less than 0.6 miles, or 1 kilometer).
As a result, scientists improved the resolution of Alpha Regio maps tenfold, predicting new geologic patterns on the surface and prompting questions about how these patterns could have formed in Alpha Regio’s mountains.
Benefits of Looking Backward
Old data offers many benefits to new missions, including information about what frequencies, parts of spectrum, or particle sizes earlier instruments covered so that new instruments can fill in the gaps.
At NASA Space Science Data Coordinated Archive, which is managed out of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, staff restore and digitize data from old spacecraft. That vintage data, when compared with modern observations, can show how a planet changes over time, and can even lead to new discoveries long after missions end. Thanks to new looks at Magellan observations, for instance, scientists recently found evidence of modern-day volcanic activity on Venus.
The three images in this carousel were taken in March 2024 at NASA Space Science Data Coordinated Archive at NASA’s Goddard Space Flight Center in Greenbelt, Md. The first shows stacked boxes of microfilm with data from Apollo missions. The middle image shows miniaturized records from NASA’s 1964 Mariner 4 flyby mission to Mars. And the final image shows a view of Jupiter from NASA’s Pioneer 10 flyby mission to the outer planets, which launched on March 2, 1972.

Magellan was among the first missions to be digitally archived in NASA’s publicly accessible online repository of planetary mission data. But the agency has reams of data — much of it not yet digitized — dating back to 1958, when the U.S. launched its first satellite, Explorer 1.
Data restoration is a complex and resource-intensive job, and NASA prioritizes digitizing data that scientists need. With three forthcoming missions to Venus — NASA’s DAVINCI and VERITAS, plus ESA’s (European Space Agency) Envision — space data archive staff are helping scientists access data from Pioneer Venus, NASA’s last mission to drop probes into Venus’ atmosphere in 1978.
Mosaic of Venus
Alpha Regio is one of the most mysterious spots on Venus. Its terrain, known as “tessera,” is similar in appearance to rugged Earth mountains, but more irregular and disorderly.
So called because they resemble a geometric parquet floor pattern, tesserae have been found only on Venus, and DAVINCI will be the first mission to explore such terrain in detail and to map its topography.
DAVINCI’s probe will begin photographing Alpha Regio — collecting the highest-resolution images yet — once it descends below the planet’s clouds, starting at about 25 miles, or 40 kilometers, altitude. But even there, gases in the atmosphere scatter light, as does the surface, such that these images will appear blurred.
Could Venus once have been a habitable world with liquid water oceans — like Earth? This is one of the many mysteries associated with our shrouded sister world. Credit: NASA’s Goddard Space Flight Center DAVINCI scientists are working on a solution. Recently, scientists re-analyzed old Venus imaging data using a new artificial-intelligence technique that can sharpen the images and use them to compute three-dimensional topographic maps. This technique ultimately will help the team optimize DAVINCI’s images and maps of Alpha Regio’s mountains. The upgraded images will give scientists the most detailed view ever — down to a resolution of 3 feet, or nearly 1 meter, per pixel — possibly allowing them to detect small features such as rocks, rivers, and gullies for the first time in history.
“All this old mission data is part of a mosaic that tells the story of Venus,” said Jim Garvin, DAVINCI principal investigator and chief scientist at NASA Goddard. “A story that is a masterpiece in the making but incomplete.”
By analyzing the surface texture and rock types at Alpha Regio, scientists hope to determine if Venusian tesserae formed through the same processes that create mountains and certain volcanoes on Earth.
