A Rocket Lab Electron rocket will kick off another busy week in spaceflight when it launches from the company’s New Zealand site on Tuesday.Astronomers Could Soon Get Warnings When SpaceX Satellites Threaten Their ViewAs American naturalist Edwin Way Teale once said, “All things seem possible in May.” Indeed, spring is in the air, and so are a bunch of rockets. NASA’s hurricane-monitoring TROPICS satellites set for launchAfter a slight delay, Rocket Lab is set to deliver a pair of hurricane-monitoring TROPICS satellites…

The inaugural launch of SpaceX’s Starship captured our imagination, but the coming week reminds us of the company’s other heavy-lift launch vehicle: Falcon Heavy. We’re also anticipating a historic spacewalk and a potentially unprecedented commercial Moon landing. Astronomers Could Soon Get Warnings When SpaceX Satellites Threaten Their ViewWe’ve also got our eyes on two Falcon 9 launches, as SpaceX continues to build its internet megaconstellation. A commercial Japanese lander will attempt a lunar landingHakuto-R snapped…

A few months after a Russian crew capsule sprung a leak while docked to the International Space Station, the MS-22 returned to Earth carrying cargo but with no crew on board.Three Astronauts May Be Stranded on the ISS After Disturbing Soyuz Coolant LeakRussian space agency Roscosmos’s Soyuz MS-22 spacecraft undocked from the ISS on Tuesday at 5:57 a.m. ET before landing in the Kazakh Steppe, an area of open grassland in northern Kazakhstan, with the help of a parachute about two hours later at 7:46 a.m. ET, according to…

The object is likely one of many Earth-observing satellites that are falling into and aligning with the space station’s orbital path, according to experts. On Monday, the Progress 83 resupply ship that’s docked to the space station fired its engines for just over six minutes, slightly raising the orbit of the ISS in order…
