Solving the mystery of frost hiding on Mars
Write a comment
A new study using data from NASA's Mars Odyssey orbiter may explain why Martian frost can be invisible to the naked eye and why dust avalanches appear on some slopes.
Scientists were baffled last year when studying images of the Martian surface taken at dawn by NASA's Mars Odyssey orbiter. When they looked at the surface using visible light - the kind that the human eye perceives - they co Examining the Heart of Webb: The Final Phase of Commissioning

NASA's James Webb Space Telescope is now experiencing all seasons - from hot to cold - as it undergoes the thermal stability test. Meanwhile, activities are underway for the final phase of commissioning: digging into the details of the science instruments, the heart of Webb. To complete commissioning, we will measure the detailed performance of the science instruments before we start routine sci NASA identifies Artemis 1 rocket issues, plans another wet dress rehearsal for June
Write a comment
NASA is targeting early June for its next attempt of the Artemis 1 wet dress rehearsal, officials announced on Thursday.
The test aims to demonstrate that the rocket can be safely loaded with propellant and practice the launch day procedures, aside from actually launching, to identify concerns and potential issues.
Previous attempts at the wet dress, conducted in April, resulted Astronaut crew returning to Earth after six months on ISS

NASA's Crew-3 mission was returning home to Earth on Thursday after six months aboard the International Space Station.
The SpaceX Dragon Endurance spacecraft with NASA astronauts Kayla Barron, Raja Chari, and Tom Marshburn, as well as European Space Agency astronaut Matthias Maurer undocked from the orbital laboratory overnight.
Their 23.5 hour journey back should see them splash down off the coast of Florida at 12:43 am on Friday (0443 GMT).
They leave behind the one Italian and three American astronauts of Crew-4, and three Russian cosmonauts.
NASA's Psyche spacecraft starts processing at Kennedy Space Center
Write a comment
Bound for an asteroid of the same name, the orbiter is undergoing final preparations for its August launch.
Since its arrival on April 29, the Psyche spacecraft has moved into the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida, where technicians removed it from its protective shipping container, rotated it to vertical, and have begun the final steps to prepare the spacecraft for launch. In the coming months, crews will perform a range of work including reinstalling solar arrays, reintegrating a radio, testing the telecommunications system, loading propellants, and encapsulating the spacecraft inside payload fairings before it leaves the facility and moves to the launch pad.
Lunar soil has the potential to generate oxygen and fuel
Write a comment
Soil on the moon contains active compounds that can convert carbon dioxide into oxygen and fuels, scientists in China report May 5 in the journal Joule. They are now exploring whether lunar resources can be used to facilitate human exploration on the moon or beyond.
Nanjing University material scientists Yingfang Yao and Zhigang Zou hope to design a system that takes advantage of lunar soil and solar radiation, the two most abundant resources on the moon. After analyzing the lunar soil brought back by China's Chang'e 5 spacecraft, their team found the sample contains compounds—including iron-rich and titanium-rich substances—that could work as a catalyst to make desired products such as oxygen using sunlight and carbon dioxide.
Based on the observation, the team proposed an "extraterrestrial photosynthesis" strategy. Mainly, the system uses lunar soil to electrolyze water extracted from the moon and in astronauts' breathing exhaust into oxygen and hydrogen powered by sunlight.

NASA will hold a media teleconference at 11 a.m. EDT on Monday, May 9, to discuss progress toward preparing the James Webb Space Telescope for science operations. 'Spot the difference' to help reveal Rosetta image secrets
Write a comment
Today, ESA and the Zooniverse launch Rosetta Zoo, a citizen science project that invites volunteers to engage in a cosmic game of 'spot the difference'. By browsing through pictures collected by ESA's Rosetta mission, you can help scientists figure out how a comet's surface evolves as it swings around the Sun.
New study reveals the effect of extended space flight on astronauts' brains
Write a comment
Long-duration space flight alters fluid-filled spaces along veins and arteries in the brain, according to new research from Oregon Health & Science University and scientists across the country.
The study published today in the journal Scientific Reports.
"These findings have important implications as we continue space exploration," said senior author Juan Piantino, M.D., assistant professor of pediatrics (neurology) in the OHSU School of Medicine. "It also forces you to think about some basic fundamental questions of science and how life evolved here on Earth."
The research involved imaging the brains of 15 astronauts before and after extended tours of duty on the International Space Station.
Researchers used magnetic resonance imaging to measure perivascular space—or the space around blood vessels—in the brains of astronauts prior to their launch and again immediately after their return. They also took MRI measurements again at one, three and six months after they had returned. Astronauts' images were compared with those taken of the same perivascular space in the brains of 16 Earth-bound control subjects.
Comparing before and after images, they found an increase in the perivascular spaces within the brains of first-time astronauts, but no difference among astronauts who previously served aboard the space station orbiting earth.
BRICS to use big data to achieve sustainable development goals
