News: The nearest solar system to our own may actually host two potentially life-supporting planets as a new candidate emerges around Alpha Centauri A, a new study reports.

The first United Arab Emirate's Hope Probe made it to the red planet on Feb 9^th. It will stay in orbit and study its atmosphere for one complete Martian year (687 days).

China's first fully homegrown Mars mission, Tianwen-1, arrived in orbit around the red planet on Feb 10^th. It will begin scouting the potential landing site for its Mars rover, due to be deployed in May.

NASA has selected SpaceX to deliver the first two segments of the moon-orbiting Gateway space station for its upcoming Artemis program, which aims to put astronauts back on the Moon.

NASA's Europa Clipper probe is scheduled to lift off in October 2024 and arrive in orbit around Jupiter in April 2030. Getting to Jupiter will be just the beginning for Clipper. The probe will then perform nearly 50 flybys of Europa over about four Earth years, studying the thickness of the moon's ice shell and assessing the habitability of its huge, buried ocean of salty liquid water, among other tasks. Clipper's observations will also help mission planners pick out promising sites for the Europa lander, if that latter mission does indeed get of the ground in the coming years.

Facts: The oldest active probe – Mars Odyssey – has been orbiting the planet for 20 years. It currently holds the record for the longest surviving continually active spacecraft in orbit around a planet other than Earth. As of October 2019 it is in a polar orbit around Mars with a semi-major axis of about 3,800 km or 2,400 miles. It has enough propellant to function until 2025.
