This article documents expected notable spaceflight events during the 2020s.
The trend towards cost reduction in access to orbit is expected to continue. In early 2023, SpaceX plans to launch its new fully reusable Starship to orbit [1] and Vulcan is planned to replace its more expensive predecessors. In late 2023, Ariane 6 is expected to replace the more expensive Ariane 5, and Blue Origin plans the maiden flight of New Glenn with a reusable first stage.
Mars stays a focus for missions to other planets, with three missions launched in 2020 (by China, the United Arab Emirates and the United States) and at least two missions planned for 2024 (India and Japan).
In 2028, as part of the NASA-ESA Mars Sample Return mission, NASA plans to launch a Sample Retrieval Lander. In 2027, ESA plans to launch the Earth Return Orbiter, which will transport the retrieved samples from Mars to Earth by 2033. China is also planning to retrieve samples from Mars by 2031.
NASA plans a return of humans to the Moon by 2025. The first uncrewed launch of the Space Launch System happened in 2022. [2] The first crewed launch is planned for 2024. In addition NASA plans to assemble the Lunar Gateway in lunar orbit. A crewed exploration of Mars could follow in the mid 2030s. SpaceX, a private company, has also announced plans to land humans on Mars in the 2020s, with the long-term goal of enabling the colonization of Mars.
India plans to launch its first crewed flight with a spacecraft called Gaganyaan on a home-grown GSLV Mark III rocket in 2024. The mission would make India the fourth nation to launch a crewed spaceflight after Russia, the US and China. India also plans to launch its second Mars probe, Mars Orbiter Mission 2 (Mangalyaan 2), in 2024.
The James Webb Space Telescope was launched in 2021. NASA plans to launch the Nancy Grace Roman Space Telescope, which will have a field of view 100 times larger than that of the Hubble Space Telescope, between October 2026 and May 2027. [3] [4] [5]
NASA's NEO Surveyor, scheduled to launch no later than June 2028, [6] is expected to be capable of detecting at least 90% of near-Earth objects larger than 140 meters (460 ft), a goal mandated by the US Congress in 2005. [7]
The number of small satellites launched annually was expected to grow to around one thousand (2018 estimate), mainly communication satellites in large constellations [8] but launches quickly exceeded this estimate, mainly due to the rapid deployment of the Starlink and OneWeb constellations. From 2020 to 2022, around 3500 Starlink satellites [9] and 500 satellites by OneWeb [10] were launched.
The National Aeronautics and Space Administration is an independent agency of the U.S. federal government responsible for the civil space program, aeronautics research, and space research. Established in 1958, NASA succeeded the National Advisory Committee for Aeronautics (NACA) to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968–1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA currently supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, the Commercial Crew spacecraft, and the planned Lunar Gateway space station.
In 2014, the maiden flight of the Angara A5, Antares 120 and Antares 130 took place.
Artemis 2 is the second scheduled mission of NASA's Artemis program and the first scheduled crewed mission of NASA's Orion spacecraft, currently planned to be launched by the Space Launch System (SLS) no earlier than September 2025. Four astronauts are to perform a flyby of the Moon and return to Earth, being the first crewed mission beyond low Earth orbit since Apollo 17 in 1972. The mission is also planned to be the first crewed launch from Launch Complex 39B of the Kennedy Space Center since STS-116 in 2006.
Artemis 3 is planned to be the first crewed Moon landing mission of the Artemis program and the first crewed flight of the Starship HLS lander. Artemis 3 is planned to be the second crewed Artemis mission and the first American crewed lunar landing since Apollo 17 in December 1972. In December 2023, the Government Accountability Office reported that the mission is not likely to occur before 2027; as of January 2024, NASA officially expects Artemis 3 to launch no earlier than September 2026.
This article documents notable spaceflight events during the year 2021. 2021 saw several spaceflight related records being set worldwide. This includes both the most orbital launch attempts and most successful orbital launches in a year. In addition, 2021 saw records set in the number of humans in orbit at one time and the most humans in space at one time.
This article documents notable spaceflight events during the year 2022. For the second year in a row, new records were set for the most orbital launch attempts and the most successful orbital launches in a year.
This article documents notable spaceflight events that have happened or are going to happen during the year 2024. Upcoming astronomical and space events for 2024 have been presented in The New York Times.
This article documents notable spaceflight events during the year 2023. For the third year in a row, new world records were set for both orbital launch attempts (223) and successful orbital launches (211) in a year.
Starship is an American two-stage super heavy lift launch vehicle under development by the aerospace company SpaceX. It is currently the largest and most powerful rocket ever flown. Starship is intended to be fully reusable, which means both stages will be recovered after a mission and reused.
The Artemis program is a Moon exploration program that is led by the United States' NASA and was formally established in 2017 via Space Policy Directive 1. The Artemis program is intended to reestablish a human presence on the Moon for the first time since Apollo 17 in 1972. The program's stated long-term goal is to establish a permanent base on the Moon to facilitate human missions to Mars.
