Astronomers ended 2021 on a excessive with the launch on December 25 of the James Webb House Telescope, a joint mission between the European House Company, Nasa and the Canadian House Company. It was a reduction to listen to that the precision drives that opened up the advanced sunshield, which is in regards to the dimension of a tennis courtroom, labored completely.
The telescope is now on the best way to its vacation spot, 1.5 million kilometres away from Earth, the place it’s going to start a collection of exams as soon as it arrives in late January. If the mission goes to plan, we are able to anticipate to start out receiving photographs from the telescope in mid-2022.
However what else lies in retailer for house science this yr? Listed here are just a few missions to be careful for.

Nasa’s Artemis programme to ship human astronauts again to the Moon in 2024 ought to get underway in 2022. The final astronauts to step foot on the Moon in 1972 made it there on a Saturn V rocket. Now Nasa has created a brand new technology of rockets, the House Launch System (SLS), which will probably be examined for the primary time in March with the launch of the Artemis 1 mission. This will probably be a three-week-long, uncrewed take a look at flight of the Orion spacecraft, which is able to embody a flyby 100km above the floor of the Moon.
Ultimately, the SLS will transport astronauts to the Lunar Gateway, the next-generation worldwide house station that will probably be positioned in orbit across the Moon and act as a approach station for missions to the floor.
The Moon can even be focused by different house companies in 2022. South Korea is hoping to launch its first lunar mission, the Korea Pathfinder Lunar Orbiter, from Cape Canaveral in August. Roscosmos, the Russian house company, plans to launch Luna 25 to the Moon’s south pole in July – over 45 years since Luna 24 returned nearly 200g of lunar soil in August 1976.
Mid 2022 will probably be a busy time for house exploration, as Nasa can even launch its Psyche asteroid mission. Psyche, which is orbiting the Solar between Mars and Jupiter, is an M-class asteroid, fabricated from metallic, so it’s just like the core of the Earth.
We’ve by no means been near an M-class asteroid earlier than, nor have we been capable of research the core of the Earth as a result of it’s too deep down, so as soon as this mission arrives in 2026 it ought to give us an entire new understanding of asteroid and planetary processes.
Not lengthy after Psyche’s journey begins, the Dart mission, which launched in November 2021, ought to arrive at its vacation spot in late September.
Dart – which stands for the double asteroid redirection take a look at – is heading to asteroid Didymos and its moonlet Dimorphos. The objective is to check what know-how it will take to save lots of the Earth from an incoming asteroid in future. Dart will intentionally crash into the smaller of the 2 our bodies, Dimorphos, to maneuver its orbit a bit bit nearer to Didymos, the bigger one. This might give priceless insights into find out how to shift any asteroid on a collision course with Earth sooner or later.
2021 was a busy yr for Mars missions with the launch of Nasa’s Perseverance rover and the Chinese language Zhurong rover, each of which proceed to ship again unimaginable photographs and information from the floor of the purple planet.
In September 2022, the European House Company is because of launch the following a part of its ExoMars mission in collaboration with Roscosmos. The primary a part of the mission, ExoMars 2016, despatched a Hint Fuel Orbiter to orbit round Mars in late 2016.
ExoMars 2022 plans to ship a Mars rover, the Rosalind Franklin, to the Martian floor to search for indicators of previous life. If the launch goes to plan, we’ll have to attend till 2023 for ExoMars to reach and for the rover to start out roaming the floor.
All in all, 2022 is seeking to be a really thrilling and fruitful time for house exploration.
