Viral infections and space travel similarly trigger inflammation and the enzymes APOBEC3C and ADAR1; researchers are developing ways to inhibit them as a means to potentially lower cancer risk for both astronauts and people on Earth. Researchers at UC San Diego Health and University of California San Diego School of Medicine are working to understand…

The long-term risks of living in space include bone loss, cosmic radiation and muscle weakness, so leaving gravity behind certainly has its obstacles — and yet, that doesn’t stop people from venturing out of the stratosphere. Some of these potential hurdles have already been studied extensively or are currently being investigated, but researchers have found…

Early returns from the US Naval Research Laboratory’s camera on NASA’s latest mission to study the Sun’s corona revealed on Dec. 4 a star more complex than ever imagined. NRL’s Wide-field Imager for Parker Solar Probe, or WISPR, the only imaging instrument aboard the NASA Parker Solar Probe mission, is now 84 percent of the…

NASA’s Parker Solar Probe captured stunning views of Venus during its close flyby of the planet in July 2020. For more insight, the WISPR team planned a set of similar observations of the Venusian nightside during Parker Solar Probe’s latest Venus flyby on Feb. 20, 2021. Mission team scientists expect to receive and process that…

A study of female astronauts has assessed the risk of blood clots associated with spaceflight. The study examines the potential risk factors for developing a blood clot (venous thromboembolism) in space. The study, published in Aerospace Medicine and Human Performance, in collaboration with King’s College London, the Centre for Space Medicine Baylor College of Medicine,…

Observations confirmed that dark coating can reduce satellite reflectivity by half. There are concerns that numerous artificial satellites in orbit could impair astronomical observations, but these findings may help alleviate such conditions. Today’s growing demand for space-based services has spawned a wave of satellite constellation projects which operate numerous artificial satellites in orbit. Since these…

Sustained low-intensity exercise does not completely counteract the effects of weightlessness on the heart muscle, which will atrophy over time in a gravity-free environment. Short bursts of repeated high-intensity activity during shorter space missions may be more successful in keeping the heart healthy. Each time a person sits or stands, gravity draws blood into the…
