NASA 的OSIRIS-REx 任务从小行星贝努(Bennu)上采集了样本、 揭示了与生命有关的重要分子,包括氨基酸和DNA和RNA中的核碱基。 氨和甲醛的存在表明在太空中形成复杂分子的条件已经成熟。 在这一帧视频中,杰森-德沃金(Jason ...
NASA 的OSIRIS-REx 任务发现了小行星贝努(Bennu)与地球上的苏尔斯湖(Searles Lake)之间的宇宙联系。两者都含有咸水蒸发形成的矿物质,这暗示着贝努的母体曾经拥有液态水库。
OSIRIS-REx launched in September 2016 and traveled 200 million miles (320 million kilometers) to reach Bennu. Once there, the spacecraft orbited the asteroid for nearly two years as flight ...
Analysis of samples taken from the asteroid Bennu reveal the presence of organic ... Collected by NASA’s OSIRIS-REx mission, these rocks and dust particles give insights into the chemistry ...
Scientists recently completed computer simulations of what would happen to Earth if it were impacted by an asteroid with a ...
While the odds of Bennu impacting Earth may sound alarming, they're not entirely unexpected. "On average, medium-sized asteroids collide with Earth about every 100–200 thousand years.
The minivan-sized OSIRIS-REx spacecraft, built by Lockheed Martin, extended its 3.35m robotic arm toward a flat patch of gravel near Bennu’s north pole and plucked the sample of rocks ...
Bennu was the target for NASA's OSIRIS-REx asteroid sampling mission, which touched down briefly on the space rock in October 2020 to gather over 4 ounces of material, and then brought that sample ...
In 2018, NASA’s OSIRIS-REx mission reached asteroid 101955 Bennu. Two years later, the spacecraft snagged a sample of its surface, which has since been returned to Earth. Now, astronomers are ...
The samples were taken from the near-Earth asteroid Bennu by the NASA mission OSIRIS-REx, the first U.S. attempt to retrieve and analyze samples from an asteroid. The findings do not show evidence ...
FILE PHOTO: The return capsule containing a sample collected from the asteroid Bennu in October 2020 by NASA's OSIRIS-REx spacecraft is seen shortly after touching down in the desert at the ...
