2023年10月11日 · Initial studies of the 4.5-billion-year-old asteroid Bennu sample collected in space and brought to Earth by NASA show evidence of high-carbon content and water, which together could indicate the building blocks of life on Earth may be found in the rock.

2025年1月29日 · In this video frame, Jason Dworkin holds up a vial that contains part of the sample from asteroid Bennu delivered to Earth by NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer) mission in 2023. Dworkin is the mission’s project scientist at NASA’s Goddard Space Flight Center in ...

2020年10月16日 · Bennu is a carbonaceous asteroid that hasn’t undergone drastic, composition-altering change, meaning that on and below its deeper-than-pitch-black surface are chemicals and rocks from the birth of the solar system.

5 天之前 · A view of eight sample trays containing the final material from asteroid Bennu. The dust and rocks were poured into the trays from the top plate of the Touch-and-Go Sample Acquisition Mechanism (TAGSAM) head. 51.2 grams were collected from this pour, bringing the final mass of asteroid sample to 121.6 grams.

2025年1月29日 · NASA’s Osiris-Rex spacecraft returned 122 grams (4 ounces) of dust and pebbles from the near-Earth asteroid Bennu, delivering the sample canister to the Utah desert in 2023 before swooping off after another space rock. It remains the biggest cosmic haul from beyond the moon.

2023年10月11日 · The sample, collected from the 4.5 billion-year-old near-Earth asteroid Bennu in October 2020 by NASA’s OSIRIS-REx mission, arrived on Earth in a capsule on September 24, dropping from the ...

2025年1月30日 · The curation team processing NASA’s asteroid Bennu sample has removed and collected 2.48 ounces (70.3 grams) of rocks and dust from the sampler hardware – surpassing the agency’s goal of bringing at least 60 grams to Earth.

2024年12月20日 · Bennu is a small, near-Earth asteroid that passes relatively close to Earth about every six years. It was the target of NASA’s OSIRIS-REx mission to collect an asteroid sample and bring it to Earth.

2025年1月29日 · A new analysis of samples from the asteroid Bennu, NASA’s first asteroid sample captured in space and delivered to Earth, reveals that evaporated water left a briny broth where salts and minerals allowed the elemental ingredients of life to intermingle and create more complex structures. The discovery suggests that extraterrestrial brines provided a crucial …

2023年10月11日 · Pieces of the asteroid Bennu, brought back to Earth in September by NASA’s OSIRIS-REx spacecraft, include crumbly rocks and dust that contain water and carbon — some of the building blocks of...
