The Double Asteroid Redirection Test (DART) was a NASA space mission aimed at testing a method of planetary defense against near-Earth objects (NEOs). [4] [5] It was designed to assess how much a spacecraft impact deflects an asteroid through its transfer of momentum when hitting the asteroid head-on. [6]
Astronaut on EVA to take asteroid samples, Orion in the background. The main objective of the Asteroid Redirect Mission was to develop deep space exploration capabilities needed in preparation for a human mission to Mars and other Solar System destinations [6] [7] per NASA's Journey to Mars flexible pathways.
The NASA Double Asteroid Redirection Test (DART) kinetic impactor spacecraft was launched in November 2021. The goal was to impact Dimorphos (nicknamed Didymoon), the 180-meter (590 ft) minor-planet moon of near-Earth asteroid 65803 Didymos. The impact occurred in September 2022 when Didymos is relatively close to Earth, allowing Earth-based ...
A 2019 NASA solar sail mission proposal selected it as a target. [7] The China National Space Administration (CNSA) is planning a robotic mission that would return samples from Kamoʻoalewa. [35] [36] This mission, Tianwen-2, is planned to launch in 2025. [37] 469219 Kamo’oalewa has been considered for use as a space station for Earth-to-Mars ...
During the mission, an uncrewed Orion capsule spent 10 days in a distant retrograde 60,000 kilometers (37,000 mi) orbit around the Moon before returning to Earth. [10] Artemis II , the first crewed mission of the program, will launch four astronauts in 2025 [ 11 ] on a free-return flyby of the Moon at a distance of 8,900 kilometers (5,500 mi).
An asteroid capable of flattening a mid-sized city could potentially collide with Earth eight years from now, as its orbit around the sun briefly intersects the path of our planet. Named 2024 YR4 ...
The mission successfully delivered NASA’s first asteroid sample collected in space to Earth in September and received a new name to honor its new target: Origins, Spectral Interpretation ...
On 25 April 2022, NASA confirmed that the mission would be extended. After dropping off its sample to Earth on 24 September 2023, the mission became OSIRIS-APEX ('APophis EXplorer'). [77] As the new name suggests, its next target will be the near-Earth asteroid (and potentially hazardous object) 99942 Apophis. Apophis will make an extremely ...
