Space Missions to Look Forward To In 2021

Space Missions to Look Forward To In 2021

  • Space exploration achieved several notable firsts in 2020 despite the COVID-19 pandemic, including commercial human spaceflight and returning samples of an asteroid to Earth.

Here are some of the missions to keep an eye in 2021

Artemis 1

  • Artemis 1 is the first flight of the Nasa-led, international Artemis program to return astronauts to the Moon by 2024.
  • This will consist of an uncrewed Orion spacecraft which will be sent on a three-week flight around the Moon.
  • IT will reach a maximum distance from Earth of 450,000 kilometres – the farthest into space that any spacecraft that can transport humans will have ever flown.
  • The Orion capsule will travel to the Moon under the power provided by a service module supplied by the European Space Agency (Esa).
  • The mission will provide engineers back on Earth with a chance to evaluate how the spacecraft performs in deep space and serve as a prelude to later crewed lunar missions. The launch of Artemis 1 is currently scheduled for late in 2021.

Mars missions

  • In February, Mars will receive a flotilla of terrestrial robotic guests from several countries.
  • The United Arab Emirates’ Al Amal (Hope) spacecraft is the Arab world’s first interplanetary mission. It is scheduled to arrive in Mars orbit on February 9, where it will spend two years monitoring the Martian weather and disappearing atmosphere.
  • Arriving within a couple of weeks after Al Amal will be the China National Space Administration’s Tianwen-1, consisting of an orbiter and a surface rover.
  • The spacecraft will enter Martian orbit for several months before deploying the rover to the surface.
  • If it succeeds, China will become the third country to land anything on Mars. The mission has several objectives including mapping the mineral composition of the surface and searching for sub-surface water deposits.
  • NASA’s Perseverance rover will land at Jezero Crater on February 18 and search for any signs of ancient life which may have been preserved in the clay deposits there. Critically, it will also store a cache of Martian surface samples on board as the first part in a highly ambitious international program to return samples of Mars to Earth.


  • In March 2021, the Indian Space Research Organisation (ISRO) is planning to launch its third lunar mission: Chandrayaan-3.
  • Chandrayaan-1 launched in 2008 and was one of the first major missions in the Indian space programme. Comprising an orbiter and a surface penetrator probe, the mission was one of the first to confirm evidence of lunar water.
  • Unfortunately, contact with the satellite was lost less than a year later.
  • There was a similar mishap with its successor, Chandrayaan-2, which consisted of an orbiter, a lander (Vikram) and a lunar rover (Pragyan).
  • It will consist of only a lander and rover, as the previous mission’s orbiter is still functioning and providing data.
  • If all goes well the Chandrayaan-3 rover will touch down in the lunar South Pole’s Aitken basin. It’s of particular interest as it is thought to host numerous deposits of subsurface water ice – a vital component for any future sustainable lunar habitation.

James Webb Space Telescope

  • The James Webb Space Telescope is the successor to the Hubble Space Telescope, but has had a rocky path to being launched.
  • Initially planned for a 2007 launch, the Webb telescope is almost 14 years late.
  • Whereas Hubble has provided some amazing views of the universe in visible and ultraviolet region of light, Webb is planning to focus observations in the infrared wavelength band.
  • The reason for this is that when observing really distant objects there will probably be gas clouds in the way.
  • These gas clouds block really small wavelengths of light, such as X-rays and ultra violet light, while longer wavelengths like infra-red, microwave and radio can get through more easily.
  • So by observing in these longer wavelengths we should see more of the universe.
  • Webb also has a much bigger mirror of 6.5-metre diameter compared to Hubble’s 2.4-metre diameter mirror – essential for improving image resolution and seeing finer detail.
  • The primary mission of Webb is look at light from galaxies at the edge of the universe which can tell us about how the first stars, galaxies and planetary systems formed. Potentially this could include some information about the origin of life as well, as Webb is planning on imaging exoplanet atmospheres in high detail, searching for the building blocks of life.
