Astronaut spots rare and ethereal 'transient luminous event' from ISS


"Transient luminous event" sounds like a euphemism for a ghost, but it's actually a beautiful phenomenon that can sometimes be seen from the International Space Station. European Space Agency astronaut and current ISS resident Thomas Pesquet shared a view of an ethereal blue glow emerging over Europe.

Transient luminous events are caused by upper-atmospheric lightning. This one happened in early September and Pesquet tweeted about it this week, calling it "a very rare occurrence."

‘Distant cosmic explosion’ was actually Russian space junk, new studies argue


Last year, a team of astronomers made a blockbuster claim, saying they had captured the most distant cosmic explosion ever—a gamma ray burst in a galaxy called GN-z11. But that flash of light—supposedly from the most distant galaxy known—has a far more prosaic explanation: It was a glinting reflection from a tumbling, spent Russian rocket that happened to photobomb observers at just the right moment, two new studies claim.

How the heck do they do that? The science behind it is, no pun intended, astronomical.

Brain damage biomarkers detected in cosmonauts after long space jaunts


Striking new research investigating blood samples taken from Russian cosmonauts before and after long stints on the International Space Station (ISS) has revealed significant elevations of several biomarkers that could indicate brain damage. The study adds to a small but growing body of research tracking the deleterious effects of space travel on the human body.

Errant Russian spacecraft thruster firing tilts space station by accident again


Unplanned thruster firings by a Russian spacecraft briefly knocked the International Space Station off-kilter today (Oct. 15), the second such incident in less than three months.

The spacecraft involved today was the Soyuz MS-18, which is scheduled to bring cosmonaut Oleg Novitskiy, film director Klim Shipenko and actor Yulia Peresild back to Earth early Sunday morning (Oct. 17). Russian flight controllers fired up the vehicle's thrusters at 5:02 a.m. EDT (0902 GMT) in a planned pre-departure test.

NASA's pioneering Lucy probe takes off to study Trojan asteroids


A first-of-a-kind NASA launch took place over the weekend, setting the agency's Lucy spacecraft on a pioneering path to study an unprecedented number of asteroids as part of a single mission. Among them are the Trojan asteroids that both trail and lead Jupiter around the Sun and are thought to be remnants of the primordial material from the formation of the Solar System's outer planets.

Lockheed Martin plans to build Starlab commercial space station by 2027


Lockheed Martin, Nanoracks, and Voyager Space have entered into a partnership to launch a permanently crewed commercial space station by 2027. Called Starlab, the semi-inflatable platform will be available to the US government and private industry.

With the International Space Station (ISS) slated for retirement and disposal by 2030, the United States is looking to private companies to provide replacements before that date under NASA's Commercial Low-Earth Orbit Destination (CLD) project.
