研究人员利用小行星2001 CA21的早期轨道预测，识别出一种可能的火星任务轨迹，可在有利的2031年窗口将总往返旅行时间缩短至约153天。

Universe Today 关注的一项研究发现，木星附近较小的特洛伊小行星并没有呈现大型天体那种清晰的颜色分化，这为早期太阳系又增添了一个新谜题。

借助在旗舰级全天区测绘任务开始前采集的早期巡天数据，Vera C. Rubin 天文台已将 11,000 颗新识别的小行星加入太阳系天体名录。

Vera C. Rubin 天文台的初步观测已发现超过 11,000 颗此前未知的小行星，为科学家在全面运行后预期的发现速度提供了早期一瞥。

Researchers studying material returned from asteroid Bennu report that organic compounds and minerals are clustered into three distinct chemical regions, suggesting that water altered the asteroid in a far more localized

Analysis of returned OSIRIS-REx samples suggests Bennu’s low thermal inertia comes from cracks within its surface rocks, helping explain why the asteroid looked so different up close than it did from Earth.

The Vera Rubin Observatory's Legacy Survey will detect one-meter class objects heading for Earth, enabling precise impact site predictions.

Fan-like patterns on Dimorphos confirm material transfer between binary asteroids, a first in planetary science.
