2021 in spaceflight
This article documents expected notable spaceflight events during the year 2021.
The James Webb Space Telescope is set to launch aboard an Ariane 5 rocket in 2021. | |
Overview
Exploration of the Solar System
Spacecrafts from three Mars exploration programs (Mars 2020, Tianwen-1, and Hope) are expected to arrive at Mars for orbit insertion in February. The Perseverance rover will attempt landing on 18 February while the Chinese lander will do so on 23 April.
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, and India will attempt once more to deliver a robotic lander to the lunar surface with Chandrayaan-3. Artemis 1 is planned to fly in November, the maiden flight of the Space Launch System and the first lunar mission for Orion. NASA is planning a crewed return to the Moon in 2024, and following that a human mission to Mars in the mid 2030s.
Human spaceflight
China plans to start the construction of the Chinese Space Station (CSS), phase 3 of its Tiangong program, with the planned launches of the Tianhe core module and Wentian lab module. It will follow the launches with crewed visits of Shenzhou 12 and Shenzhou 13, interspersed with Tianzhou cargo deliveries.
Space Telescope
The long-delayed James Webb Space Telescope, the largest space telescope ever built, is planned to be launched to the Sun–Earth L2 point by a European Ariane 5 rocket in October.[1]
Rocket innovation
The trend towards cost reduction in access to orbit is expected to continue. Arianespace's Ariane 6 will make its maiden flight,[2] targeting a per-satellite launch cost similar to a Falcon 9.[3] United Launch Alliance plans to debut their Vulcan rocket, which was designed to gradually replace Atlas V at lower costs.[4] Blue Origin plans to launch its first orbital-class New Glenn rocket with a reusable first stage.[5] Northrop Grumman plans to carry out the maiden launch of the Omega launch vehicle.[6] SpaceX plans the first commercial flight of the fully reusable Starship.[7] 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.
