2020年10月22日 Tagging Bennu Image Credit: OSIRIS-REx, University of Arizona, NASA, Goddard Scientific Visualization Studio Explanation: On October 20, after a careful approach to the boulder-strewn surface, the OSIRIS-REx spacecraft’s arm reached out and touched asteroid Bennu. Dubbed a Touch-And-Go (TAG) sampling event, the 30 centimeter wide sampling h...
Bennu, a well-preserved, ancient asteroid, is currently more than 200 million miles (321 million kilometers) from Earth and offers scientists a window into the early solar system as it was first taking shape billions of years ago and flinging ingredients that could have helped seed life on Earth. On Tuesday, Oct. 20, 2020, NASA’s OSIRIS-REx sample collection...
This illustration shows the hot, dense, expanding cloud of debris stripped from neutron stars just before they collided. This cloud produces a kilonova; that is an astronomical event that occurs when two neutron stars or a neutron star and a black hole merge into each other. This cloud shows the visible and infrared light. Within this neutron-rich debris, la...
NASA的OSIRIS-REx任务已经做好了接触小行星本努表面的准备。 影像来源：美国国家航空航天局/戈达德/亚利桑那大学 NASA的源光谱释义资源安全风化层辨认探测器(OSIRIS-REx)周二展开了它的机械手臂，这是该机构首次短暂接触一颗小行星，收集小行星表面的尘埃和鹅卵石，并于2023年将其送往地球。 这颗保存完好的古老小行星，名为贝努，目前距离地球超过2亿英里（3.21亿公里）。贝努为科学家们打开了一扇窗口，了解数十亿年前太阳系最初形成时的情况，并为地球提供了可能帮助孕育生命的成分。如果周二的样本采集活动，也就是所谓的“触碰即走”（TAG）提供了足够的样本，能够提供足够的样本，任务团队将命令航天器开始存放珍贵的原始货物，并于2021年3月开始返回地球的旅程。否则，他们将为明年1月的另一次尝试做准备。 “...

Two of Orion’s four recently installed solar array wings are exposed and surrounded by the panels that will protect it during launch and ascent. Three spacecraft adapter jettison fairings are being prepared for installation and will be moved into place by technicians with Lockheed Martin, lead contractor for Orion. They will be secured around the spacecraft,...
