NASA officials cleared Boeing’s Starliner crew capsule for launch next week in a flight readiness review Wednesday, moving a step closer toward a critical unpiloted demonstration flight to attempt docking at the International Space Station and check off other test objectives left unaccomplished on a problem-plagued mission two-and-a-half years ago.

Northrop Grumman says it has a backup plan to fulfill the company’s contract to resupply to the International Space Station if the war in Ukraine continues to disrupt the supply of Russian engines and Ukrainian booster cores for the company’s Antares rocket.
Scott Alan Johnston (that’s me!) joined the Universe Today team just over a year ago. Since then, I’ve written over 50 space news stories for the website – time flies when you’re having fun! But when I’m not writing articles here on Universe Today, I’m a historian of science, and I recently released a new book about the history of timekeeping.
Evidence is growing that Mars, now cold and dry, had liquid water running on its surface much more recently than previously thought.
Like every solar-panel-powered vehicle on Mars, maintaining electrical power always becomes an issue at some point in the mission. Last week, mission controllers at the Jet Propulsion Laboratory lost contact with the Ingenuity Mars Helicopter. While they were able to re-establish communications, which is done through the Perseverance rover, engineers know that keeping Ingenuity’s batteries charged is going to be increasingly difficult as the dark winter is on the way to Jezero Crater.
Our Solar System contains eight planets and more than 200 moons. The large majority of those moons have no chance of being habitable, but some of them—Europa and Enceladus, for example—are strong candidates in the search for life.
On March 17th, the Artemis I mission rolled out of the Vehicle Assembly Building (VLB) and was transferred to Launch Complex 39B at the NASA Kennedy Space Center in Florida. This was the first time that a fully-stacked Space Launch System (SLS) and Orion spacecraft were brought to the launchpad in preparation for a “wet dress rehearsal.” To mark the occasion, NASA released a video of the event that featured a new song by Pearl Jam’s Eddie Vedder (“Invincible”).

Europe’s new Vega C launcher is on track for its inaugural flight from the European spaceport in Kourou, French Guiana, during the second half of June, according to officials managing final phases of integration.
China's Zhurong Mars rover is adjusting to its first winter on the Red Planet while its companion orbiter continues to map the world from above.
From dodging space debris to welcoming the first-ever fully private astronaut mission to the International Space Station, SpaceX's Crew-3 mission had a very eventful six months off Earth.
Liquid water once shaped the rock inside a meteorite from Mars, but likely did not support any microbial life, a new study finds.
The Chandrasekhar limit determines whether a star ends its life as a smoldering white dwarf or explodes in a supernova becoming a neutron star or black hole.

'Dinosaur Apocalypse,' a PBS NOVA special narrated by Sir David Attenborough, attempts to reconstruct the day Earth was hit by an asteroid 66 million years ago.
What a massive volcanic eruption looks like from space. The GOES-17 satellite captured images of an umbrella cloud generated by the underwater eruption of the Hunga Tonga-Hunga Ha’apai volcano on Jan. 15, 2022. The Tonga eruption sent crescent-shaped bow shock waves through the atmosphere, as well as numerous lightning strikes.
