China’s Tianwen-2 mission has captured the first close-up images of Kamoʻoalewa (2016 HO3), Earth’s smallest known quasi-satellite, during a recent approach. The tiny asteroid (roughly 40–100 meters across) is being studied to understand its origin and orbital evolution, with plans to collect samples for return to Earth later this year despite the challenges of its irregular, rapidly spinning surface.
China's Tianwen-2 mission captured the first close-up of Kamo'oalewa, Earth's rare minimoon and quasi-satellite, after a near-billion-kilometer voyage; the mission will study the asteroid and return rock samples to Earth, potentially clarifying its origin and whether it's a fragment of the Moon.
After a seven-year journey plagued by fuel leaks, communications glitches, and a sampling system that failed to fire, JAXA’s Hayabusa capsule returned to Earth in 2010 with a 40-centimeter container carrying the first asteroid samples from Itokawa. Although the sampling mechanism didn’t fire, the touchdown disturbed the surface enough for about 1,500 dust grains to be collected, later identified as Itokawa material and tied to the LL chondrite meteorite class for the first time. The mission proved sample return from an asteroid was feasible and informed its successor, Hayabusa2, with broader context later enriched by OSIRIS-REx findings from Bennu.
This week at NASA, the sample return capsule from the OSIRIS-REx mission landed on Earth, marking the successful completion of NASA's first asteroid sample return mission. NASA astronaut Frank Rubio returned to Earth after spending a record-setting 371 days in space. Progress was made on the Artemis II mission, with all four RS-25 engines installed onto the core stage of the Moon rocket. Additionally, an annular solar eclipse is set to occur on October 14, crossing the U.S. from Oregon to Texas.
NASA's OSIRIS-REx mission successfully returned a capsule carrying rock samples from the asteroid Bennu, marking the first U.S. asteroid sample-return mission. The samples, expected to be around 8.8 ounces, could provide molecular clues about the history of the solar system and the origin of life on Earth. Bennu, a carbon-rich asteroid, is believed to be a remnant of the early solar system and its rocks carry a record of the forces and processes that shaped Earth. The mission's success opens the door for further exploration and study of asteroids.
NASA's OSIRIS-REx mission is set to make history on September 24, 2023, as it returns samples of the asteroid Bennu to Earth after seven years in deep space. The spacecraft will land at the Department of Defense's Utah Test and Training Range near Dugway, Utah, using a special capsule and parachute. Scientists are eagerly awaiting the landing, which marks the end of the mission that began in 2016.
China's Academy of Aerospace Solid Propulsion Technology has successfully conducted high-altitude parachute deployment tests for the Tianwen-2 asteroid sample return and comet rendezvous mission, scheduled to launch in May 2025. The mission will target the near-Earth asteroid 469219 Kamoʻoalewa, and the parachute will be used to slow the descent of a return capsule carrying a sample container after reentering the Earth’s atmosphere. China is also working on an unprecedented Mars sample return mission and planning an asteroid deflection test for 2025.
