In News: The launch of a keenly awaited space mission that is being seen as the start of a new age in space exploration had to be put off due to some problems.
- NASA’s Artemis 1 mission is aimed at exploring the Moon with the specific objective of getting human beings back on the lunar surface and possibly beyond — to Mars and elsewhere.
Artemis 1
- Artemis 1 is all about laying the foundations for more complex and ambitious missions.
- It is carrying several payloads in the form of small satellites called CubeSats, each of which is equipped with instruments meant for specific investigations and experiments.
- Then there are biology experiments, investigating the behaviour of small organisms like fungi and algae in outer space, and the effect of radiation, especially the reaction on their genes.
- The Orion spacecraft, which is specifically designed to carry astronauts into deep space on future missions, will have three dummy ‘passengers’ — mannequins made of material that mimic human bones, skin, and soft tissue.
- These would be equipped with a host of sensors to record the various impacts of deep space atmosphere on the human body.
- The rocket that is being used for the Artemis missions, called Space Launch System, or SLS, is the most powerful ever built.
- The giant, 98-metre-tall rocket, weighing 2,500 tonnes, can help the Orion spacecraft achieve speeds of over 36,000 km per hour, and take it directly to the Moon.
