NASA-JAXA XRISM Mission Sees Pulsar Gathering Companion’s ‘Wind’
By NASA
Quick Summary
Using data from the Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) observatory, astronomers have directly observed a giant star’s outflow, called a stellar wind, being captured by its compact companion and providing the power source for strong X-ray flares. The research is part of NASA’s exploration of the extreme universe to better understand how the […]
Space Explainer: The ISS & Life in Orbit
The International Space Station has been continuously staffed since November 2000, making it the longest-running human outpost off Earth. It orbits roughly 400km up, circling the planet every 90 minutes at about 28,000 km/h — meaning the crew sees a sunrise or sunset every 45 minutes.
Crew members typically rotate every 5-6 months, arriving and departing on Soyuz or Crew Dragon spacecraft. Their days are tightly scheduled around scientific experiments in microgravity, station maintenance, and roughly 2.5 hours of mandatory daily exercise to counteract the bone and muscle loss that comes from living without gravity.
