This article documents notable spaceflight events during 2021.


Exploration of the Solar System

Spacecraft from three Mars exploration programs (Mars 2020, Tianwen-1, and Hope) arrived at Mars in February. The Perseverance rover landed on 18 February while the Chinese lander and rover will do so in mid May, after conducting geological survey of Martial surface for its landing site from orbit.

Lucy, a NASA space probe will launch and begin a 12-year journey to seven different asteroids, visiting six Jupiter trojans, and one Main Belt asteroid.[1] Trojans are asteroids which share Jupiter's orbit around the Sun, orbiting either ahead of or behind the planet.

The Double Asteroid Redirection Test (DART) is planned to launch in November on a Falcon 9. It is a space probe that will visit the double asteroid Didymos and demonstrate the kinetic effects of crashing an impactor spacecraft into an asteroid moon for planetary defense purposes. The mission is intended to test whether a spacecraft impact could successfully deflect an asteroid on a collision course with Earth.

The Juno probe will continue its exploration of Jupiter. Originally, its mission was intended to conclude on 31 July by burning up in Jupiter's atmosphere following its 35th perijove. However, on 8 January 2021, NASA announced that the probe was granted a second mission extension through September 2025, which could include future fly-bys of Europa and Io.[2][3]

Lunar exploration

Multiple spaceflights to the Moon are planned to take place in 2021. As part of NASA's Commercial Lunar Payload Services program, the launches of commercial landers developed by Astrobotic Technology and Intuitive Machines are scheduled. Russia plans to resume its Luna-Glob exploration programme with the Luna 25 lander. Artemis 1 is planned to fly in November, the first flight of the Space Launch System and the first lunar mission for Orion.

Human spaceflight

China plans to begin construction of the Chinese Space Station (CSS), phase 3 of the Tiangong program, with the launch of the Tianhe core module in late April. Crewed visits to the station will commence with Shenzhou 12 and Shenzhou 13 starting in early June, preceded with Tianzhou cargo deliveries.[4]

In the United States, Boeing's CST-100 Starliner will conduct a second uncrewed test flight in August in advance of a first crewed test flight in late 2021.[5]

Space telescopes

The long-delayed James Webb Space Telescope, the largest optical space telescope ever built, is planned to be launched to the Sun–Earth L2 point by a European Ariane 5 rocket in October.[6]

Rocket innovation

The trend towards cost reduction in access to orbit is expected to continue. United Launch Alliance plans to debut their Vulcan rocket, which was designed to gradually replace Atlas V and Delta IV Heavy at lower costs.[7] Mitsubishi Heavy Industries's H3 launch vehicle, scheduled to enter service this year, will cost less than half that of H-IIA, its predecessor.[8] After suborbital tests in 2020, SpaceX plans to conduct the first orbital flight of the fully reusable Starship launch vehicle.[9] Multiple other companies plan to introduce smaller rockets.

Orbital launch statistics

By country

For the purposes of this section, the yearly tally of orbital launches by country assigns each flight to the country of origin of the rocket, not to the launch services provider or the spaceport. For example, Soyuz launches by Arianespace in Kourou are counted under Russia because Soyuz-2 is a Russian rocket.
