Molten Iron Rain Falls Through the Skies of Scorching-Hot Exoplanet

A new study reports that iron rain likely falls through the thick, turbulent air of WASP-76 b, a bizarre “ultrahot Jupiter” that lies about 640 light-years from the sun, in the constellation Pisces. Space.com reports: WASP-76 b zips around its host star once every 1.8 Earth days, an orbit so tight that the gaseous planet is “tidally locked,” always showing the…

Two Private Satellites Dock In Space In Historic First For Orbital Servicing

Mars Is a Seismically Active World, First Results From NASA’s InSight Lander Reveal

The first results from NASA’s quake-hunting InSight Mars lander just came out, and they reveal that Mars is a seismically active planet. Space.com reports: Martian seismicity falls between that of the moon and that of Earth, [says InSight principal investigator Bruce Banerdt, of NASA’s Jet Propulsion Laboratory]. “In fact, it’s probably close to the kind of seismic activity you would expect…

2 Satellites Will Narrowly Avoid Colliding Over Pittsburgh On Wednesday

Two defunct satellites traveling at 32,800 mph will narrowly miss colliding with one another over Pittsburgh on Wednesday evening. “If the two satellites were to collide, the debris could endanger spacecraft around the planet,” reports Space.com. From the report: It will be a near miss: LeoLabs, the satellite-tracking company that made the prediction, said they should pass between 50 feet and…

NASA’s Curiosity Rover Recovers From Glitch on Mars

NASA’s Mars rover Curiosity “lost its orientation…partway through its last set of activities,” reported a planetary geologist on the rover’s team Monday. Curiosity had lost track of its position in space and the position of its various parts like its robotic arm. “Thus, Curiosity stopped moving, freezing in place until its knowledge of its orientation can be recovered. Curiosity kept sending…
