The gibbous Moon passes through Leo and Virgo as it waxes toward full, forming new Moon-and-stars "lunarisms" (patterns) each evening. Mercury begins a new apparition in the sunset. At dawn, Jupiter emerges to join the lineup of Venus, Mars, and Saturn.

Live coverage of the countdown and launch of a SpaceX Falcon 9 rocket from pad 39A at the Kennedy Space Center in Florida on Axiom’s Ax-1 mission. The Ax-1 mission will carry Michael López-Alegría, Larry Connor, Eytan Stibbe, and Mark Pathy to the International Space Station. Follow us on Twitter.

SpaceX will launch a former NASA astronaut and three paying customers on a journey to the International Space Station. That mission, called Ax-1, lifts off today (April 8)!

The Copernicus Sentinel-2 mission takes us over part of Sindh – the third-largest province of Pakistan.

A contract signed with Arianespace secures the launch for the third Copernicus Sentinel-1 satellite. Scheduled to lift off on ESA’s new Vega-C rocket from Europe’s Spaceport in French Guiana in the first half of 2023, Sentinel-1C will continue the critical task of delivering key radar imagery for a wide range of services, applications and science – all of which benefit society.

The first all-private crewed mission to the International Space Station is ready to fly, mission leaders announced today (April 7).

First came the "Maggots." Then the "Bugs." Now the latest infestation to take over NASA's Astronaut Office has been identified. The 23rd group of astronaut candidates has their nickname, "The Flies."
