A SpaceX Falcon 9 rocket with the company’s Crew Dragon spacecraft onboard is seen on the launch pad at Launch Complex 39A at sunrise as preparations continue for the Demo-2 mission, Wednesday, May 27, 2020, at NASA’s Kennedy Space Center in Florida. NASA’s SpaceX Demo-2 mission is the first launch with astronauts of the SpaceX Crew Dragon spacecraft and Falcon 9 rocket to the International Space Station as part of the agency’s Commercial Crew Program. The test flight serves as an end-to-end demonstration of SpaceX’s crew transportation system. Robert Behnken and Douglas Hurley are scheduled to launch at 4:33 p.m. EDT on Wednesday, May 27, from Launch Complex 39A at the Kennedy Space Center. A new era of human spaceflight is set to begin as…

2020 March 5 The Light, the Dark, and the Dusty Image Credit & Copyright: Casey Good Explanation: This colorful skyscape spans about four full moons across nebula rich starfields along the plane of our Milky Way Galaxy in the royal northern constellation Cepheus. Near the edge of the region’s massive molecular cloud some 2,400 light-years away, bright reddish emission region Sharpless (Sh) 155 is left of center, also known as the Cave Nebula. About 10 light-years across the cosmic cave’s bright walls of gas are ionized by ultraviolet light from the hot young stars around it. Dusty blue reflection nebulae, like vdB 155 at lower right, and dense obscuring clouds of dust also abound on the interstellar canvas. Astronomical explorations have revealed other dramatic signs…

2020 February 28 South Celestial Rocket Launch Image Credit & Copyright: Brendan Gully Explanation: At sunset on December 6 a Rocket Lab Electron rocket was launched from a rotating planet. With multiple small satellites on board it departed on a mission to low Earth orbit dubbed Running Out of Fingers from Mahia Peninsula on New Zealand’s north island. The firey trace of the Electron’s graceful launch arc is toward the south in this southern sea and skyscape. Drifting vapor trails and rocket exhaust plumes catch the sunlight even as the sky grows dark though, the setting Sun still shinning at altitude along the rocket’s trajectory. Fixed to a tripod, the camera’s perspective nearly aligns the peak of the rocket arc with the South Celestial Pole,…

2019 August 9 Atlas at Dawn Image Credit & Copyright: Michael Seeley Explanation: This single, 251-second long exposure follows the early flight of an Atlas V rocket on August 8, streaking eastward toward the dawn from Cape Canaveral Air Force Station, planet Earth. The launch of the United Launch Alliance rocket was at 6:13am local time. Sunrise was not until 6:48am, but the rocket’s downrange plume at altitude is brightly lit by the Sun still just below the eastern horizon. Waters of the Indian River Lagoon in Palm Shores, Forida reflect subtle colors and warming glow of the otherwise calm, predawn sky. The mighty Atlas rocket carried a military communications satellite into Earth orbit. Of course, this weekend the streaks you see in clear skies…

 SpaceX第18次空间站货运补给(CRS-18)任务完整版 来源：SpaceX 北京时间7月26日6时1分，SpaceX在卡角空军基地SLC-40发射平台执行第18次空间站货运补给(CRS-18)任务，给空间站送去大约2268千克（5000磅）的货物。错过直播的小伙伴，可以观看上面的完整版视频。 这一期的有什么看点呢？ 来源:SpaceX 首先，这次任务中的货运龙飞船一艘“三手”货运飞船，先前在CRS-6任务（2015年4月）和CRS-13任务（2017年12月）中使用过，这是SpaceX首艘三次前往空间站的货运飞船，为纪念这一成就，这艘龙飞船上贴了两个空间站的标志，同时还有一个阿波罗50周年的标志。 但这并不是最后一个，接下来的CRS-19和CRS-20，也将使用“三手”货运龙飞船。 在昨天的新闻发布会上，SpaceX高管说，目前SpaceX有13艘龙飞船，每艘大约1.5年飞一次，在退休前总共飞三次。 猎鹰9号一级火箭回收 来源：SpaceX 二：SpaceX成功在卡角空军基地陆地着陆区1(LZ-1)回收了猎鹰9号一级火箭。 展开的太阳能板 来源：SpaceX 三：这艘龙飞船预计于北京时间7月27日20时30分被空间站机械臂捕获，并于北京时间28日凌晨开始安装。 小型隔热片（small heat-shield tiles） 来源：SpaceX 四：在SpaceX的这次任务中，龙飞船上还增加了新硬件，小型隔热片，如上图圆框处，目的是为了收集数据，用于未来的星际飞船。 参考： [1]https://www.spacex.com/sites/spacex/files/crs-18_mission_press_kit_1.pdf [2]https://www.spacex.com/webcast [3]https://www.space.com/spacex-crs-18-launch-third-dragon-flight.html

2019 July 27 Chandrayaan 2 Launch Image Credit & Copyright: Neeraj Ladia Explanation: On July 22nd this GSLV (Geosynchronous Satellite Launch Vehicle) MkIII rocket vanished from sight into a cloud bank an instant after this dramatic snapshot was taken. Launched from India’s Satish Dhawan Space Centre it carried the Chandrayaan 2 mission spacecraft into Earth orbit. The spacecraft’s orbiter, lander, and rover are destined for the Moon, though. In the coming weeks it will perform a series of orbit raising maneuvers, eventually transferring to lunar orbit in early September. Carrying the solar-powered rover, the lander is scheduled to separate and attempt its autonomous soft landing at high latitudes near the lunar south pole. It should arrive on the lunar nearside near local sunrise and the…
