3 天之前 · Bennu is a relatively small asteroid that passes close to Earth about every six years. Bennu was the target of NASA's OSIRIS-REx, the first U.S. mission to collect a sample from an asteroid and deliver it to Earth on Sept. 24, 2023. Bennu is about one-third of a …

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.

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30日 · OSIRIS-REx is the first U.S. mission to collect a sample from an asteroid. It returned to Earth on Sept. 24, 2023, to drop off a capsule with material from asteroid Bennu. After dropping off the sample capsule through Earth's atmosphere, the spacecraft was renamed OSIRIS-APEX and sent on a new mission to explore asteroid Apophis in 2029.

3 天之前 · 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. Bennu is a carbon-rich asteroid that is about one …

2025年1月29日 · Nearly 60 years later, NASA’s OSIRIS-REx mission returned from space with a sample of an asteroid named Bennu, similar to the one that rained rocks over Revelstoke. Our research team has published a chemical analysis of those samples, providing insight into how some of the ingredients for life may have first arrived on 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 setting for the development of ...

101955 Bennu (provisional designation 1999 RQ 36) is a carbonaceous asteroid in the Apollo group discovered by the LINEAR Project on 11 September 1999. It is a potentially hazardous object that is listed on the Sentry Risk Table and has the third highest cumulative rating on the Palermo Technical Impact Hazard Scale. [9]

2020年10月8日 · As Bennu’s rotation decelerates, a highly detailed view of the asteroid is revealed using 20cm terrain elevation data (OLA) and high resolution imagery (PolyCam). The camera then zooms in and flys over several locations - Simurgh, Roc, Gargoyle, and Ocypete.
