Blue Origin has delayed the fourth crewed mission of its New Shepard suborbital vehicle by two days, to no earlier than Thursday, March 31, citing high winds at the company's West Texas launch site.
Scientists will have to wait a little longer to get their hands on pristine Mars samples that might hold evidence of ancient Red Planet life. They had hoped to try and retrieve them in 2026, but no.
Under the current limits, set by NASA in 1989, the effective dose limit for an astronaut's career is based on a maximum 3% lifetime excess risk of cancer mortality. So why is there a lower career limit for radiation exposure for female astronauts than for male astronauts?

A galaxy's overdeveloped spiral arm dominates the foreground of a stunning new image from the Gemini Observatory in Hawaii. The image captures a lopsided spiral galaxy known as NGC 772, which lies over 100 million light-years from Earth in the constellation Aries.
NASA's flying observatory is on the chopping block again. The White House's 2023 federal budget request allocates no money to NASA's Stratospheric Observatory For Infrared Astronomy (SOFIA), a modified Boeing 747 jet equipped with an 8.2-foot-wide (2.5 meters) telescope.
Giant "sinkholes"- one of which could devour an entire city block holding six-story buildings - are appearing along the Arctic seafloor, as submerged permafrost thaws and disturbs the area, scientists have discovered.
Keeping technical systems in top shape helps Ukraine's defense forces stay ahead of Russian aggressors. But with a lack of in-house experts, the military has to rely on capable volunteers. Aerospace student Ihor has answered that call.
