Astronauts collect blood aboard the ISS | Space photo of the day for July 21, 2025
(Image credit: NASA)Aboard the International Space Station, astronauts work to study how the microgravity atmosphere affects human health, such as muscle development and bone structure.What is it?As part of a project to look at how microgravity affects cellular health, ISS Commander Takuya Onishi of JAXA (Japan Aerospace Exploration Agency) and NASA Expedition 73 Flight Engineer Nichole Ayers collect blood samples from the astronauts on the space station.
Given that gravity is almost nonexistent on the ISS, it can make things like blood collection somewhat challenging, as things float away or have to be tied down.Where is it?This photo was taken aboard the ISS, around 250 miles (402 km) from Earth in low-Earth orbit. The crew on the ISS works to collect blood from other crew members. (Image credit: NASA)Why is it amazing?The blood being collected in...
Crew-8 astronauts remain mum about post-splashdown medical issue
NASA Space Technology WASHINGTON — The three NASA astronauts who returned to Earth on the Crew-8 mission declined to discuss the medical issue that prompted a trip to the hospital after their return and, for one of them, an overnight stay.NASA astronauts Michael Barratt, Matthew Dominick and Jeanette Epps, along with Roscosmos cosmonaut Alexander Grebenkin, returned to Earth Oct. 25 on a Crew Dragon spacecraft, concluding the 235-day Crew-8 mission. But later that day NASA said that the four were taken to a Pensacola, Florida, hospital for additional medical evaluations “out of an abundance of caution.” One of the NASA astronauts was hospitalized in stable condition there, but released the next day “in good health.”NASA did not disclose the identity of the astronaut who was hospitalized or the specific medical concern that prompted the hospital...

Astronaut’s photo shows Earth as you’ve never seen it before
NASA Space Technology Don Pettit / NASANASA astronaut Don Pettit already has a long-held reputation for creating stunning space photography, and his latest effort will only bolster it.Shared on social media on Thursday, the image (top) shows Earth as a blaze of streaking light, an effect created by using a long and multiple exposures to capture cities at night across several continents.But the photograph, captured from the International Space Station (ISS) where Pettit arrived in September on his fourth orbital mission, also features lots of other goodies, including perhaps the first ISS image to show both a sunset and sunrise in a single frame. Circular star trails above Earth are also visible, and if you look closely enough you might also be able to see lightning flashes and aurora.New star trails photography is back!This 30-minute...
