Dragon Returns Space Station Science to Earth

Earth's horizon and stars in background with reentering spacecraft visible as small streak of orange
NASA astronaut Jack Fischer photographed the SpaceX Dragon capsule as it reentered Earth's atmosphere before splashing down in the Pacific Ocean west of Baja California at 8:12 a.m. EDT, July 3, 2017. Fischer commented, "Beautiful expanse of stars-but the “long” orange one is SpaceX-11 reentering! Congrats team for a successful splashdown & great mission!"

A variety of technological and biological studies conducted on the International Space Station are returning in Dragon. The Fruit Fly Lab-02 experiment seeks to better understand the effects of prolonged exposure to microgravity on the heart. Samples from the Systemic Therapy of NELL-1 for osteoporosis will return as part of an investigation using rodents as models to test a new drug that can both rebuild bone and block further bone loss, improving crew health. The Cardiac Stem Cells experiment investigated how microgravity affects stem cells and the factors that govern stem cell activity.

The Dragon spacecraft launched June 3 on a SpaceX Falcon 9 rocket from historic Launch Complex 39A at NASA’s Kennedy Space Center in Florida, and arrived at the station June 5.

Dragon返回空间站科学到地球

地球的地平线和背景中的星星与重新进入的航天器可见橙色的小条纹
美国宇航局宇航员杰克·菲舍尔(Jack Fischer)在2017年7月3日美国东部时间上午8点12分,在SpaceX龙胶囊重新打入了地球的气氛,然后在下加利福尼亚州西部的太平洋飞溅下来。菲舍尔评论说:“美丽的星星 - 但是长的“橙色的是SpaceX-11重新进入!恭喜团队成功的飞溅和伟大的使命!”

在国际空间站进行的各种技术和生物学研究都在龙归来。 Fruit Fly Lab-02实验旨在更好地了解长时间暴露于微重力对心脏的影响。来自NELL-1用于骨质疏松症的系统治疗的样品将作为使用啮齿动物进行调查的一部分返回,以测试能够重建骨骼并阻止进一步骨丢失,改善船员健康的新药物。心脏干细胞实验研究了微重力如何影响干细胞和干细胞活性的因素。

龙飞船于6月3日在美国宇航局肯尼迪航天中心的佛罗里达州历史悠久的发射复合体39A发射的SpaceX Falcon 9火箭上发射,并于6月5日抵达该处。
