太空探索技术公司载人2号任务发射
2021年04月24日 Streak and Plume from SpaceX Crew-2 Launch Video Credit & Copyright: Eric Holland Explanation: What’s happening in the sky? The pre-dawn sky first seemed relatively serene yesterday morning over Indian Harbor Beach in Florida, USA. But then it lit up with a rocket launch. Just to the north, NASA’s SpaceX Crew-2 Mission blasted into space aboard a powerful Falcon 9 rocket. The featured time-lapse video — compressing 12-minutes into 8-seconds — shows the bright launch plume starting on the far left. The rocket rises into an increasingly thin atmosphere, causing its plume to spread out just as it is lit by the rising Sun. As the Crew-2 capsule disappears over the horizon, the landing plume of the returning first stage of the Falcon 9…
天问一号前往火星
7月25日 Tianwen-1 Mission to Mars Image Credit & Copyright: Jeff Dai (TWAN) Explanation: On July 23, this Long March 5 heavy-lift rocket rose into a blue morning sky from China’s Hainan Island Wenchang Satellite Launch Center. The rocket carried an orbiter, lander, and rover to ask Heavenly Questions on the ambitious Tianwen-1 mission to Mars. In fact Tianwen-1 was the second of three missions scheduled for a July departure to the Red Planet. The United Arab Emirates launched its Amal (Hope) Mars probe on July 19. NASA’s launch of its Mars Perseverance Rover from Cape Canaveral Air Force Station, USA is scheduled for July 30. That is the last planned Mars launch for 2020 though. The minimum-energy launch window for an expedition to Mars is…
猎鹰9号火箭返回
2020 March 12 Falcon 9 Boostback Image Credit & Copyright: John Kraus Explanation: Short star trails appear in this single 84 second long exposure, taken on March 6 from a rotating planet. The remarkable scene also captures the flight of a Falcon 9 rocket and Dragon cargo spacecraft over Cape Canaveral Air Force Station shortly after launch, on a resupply mission bound for the International Space Station. Beginning its return to a landing zone about 9 kilometers from the launch site, the Falcon 9 first stage boostback burn arcs toward the top of the frame. The second stage continues toward low Earth orbit though, its own fiery arc traced below the first stage boostback burn from the camera’s perspective, along with expanding exhaust plumes from…
RockOn!和RockSat-C:把学生实验设备发射到太空
2019年6月20日美国东部时间周四凌晨5点30分，一枚40英尺高的火箭从美国宇航局位于弗吉尼亚州的瓦勒普斯飞行基地发射升空，火箭上载有28个学生实验设备(测量加速度、湿度、压力、温度和辐射计数)。 这次发布是RockOn!项目的一部分！这个项目旨在帮助学生学习和应用亚轨道太空飞行建筑实验技能的课程。来自美国各地的200多名大学生见证了他们在美国宇航局亚轨道探测火箭上进行的实验。 参与者在RockOn!接收关于开发用于亚轨道火箭飞行的科学有效载荷所需的基础知识的指导。在学习了RockOn!的基础知识后，学生可以参加RockSat-C项目，在这个项目中，他们在整个学年期间设计并构建一个更复杂的实验。 At 5:30 a.m. EDT Thursday, June 20, 2019, a 40-foot tall rocket carrying 28 student experiments (measuring acceleration, humidity, pressure, temperature and radiation counts) launched from NASA’s Wallops Flight Facility in Virginia. The launch is part of the RockOn! programs designed for students to learn and apply skills in building experiments for suborbital space flight. More than 200 university students from across the United States witnessed the launching of their experiments aboard a NASA suborbital sounding rocket. Participants in RockOn! receive instruction on the basics required to develop a scientific payload for flight on a suborbital rocket. After learning the basics in RockOn!, students may then participate in RockSat-C, where during the school year they design and build a more complicated experiment….
