Every time I see stories like this I want to fire up some mod/sim software and try to simulate it. There must be some open source or public domain software for this but needs a hefty computer...hmm...brain rationalizing... #space #sciencearstechnica.com/science/2019/0…
I really liked his explanation targeted at the every day viewer. Very well done. Also learned something new. I didn't realize the Soviet rockets rotate the launch pad instead of doing a roll program at launch. #space
I have seen reports on the nature of the errors (basically computer was asked to compute more than it had capacity for) but not the why or the fail-over modes if the condition persisted. Great article #space #retrocomputing
India is planning on launching its own Salyut-class space station in the next decade. That's about twice the size of the Chinese Tiangong stations launched to date but a third the size of their next planned one, and 1/20th the size of the ISS. #space
India plans to have its own space station in the future and conduct separate missions to study the Sun and Venus, it said on Thursday, as the nation moves to bolster its status as a leader in space technologies and inspire the young minds to take an interest in scientific fields. India’s spac…
Why did a picturesque volcanic eruption in Iceland create so much ash? Although the large ash plume was not unparalleled in its abundance, its location was particularly noticeable because it drifted across such well-populated areas. The Eyjafjallajökull volcano in southern Iceland began erupting on 2010 March 20, with a second eruption starting under the center of a small glacier on 2010 April 14. Neither eruption was unusually powerful. The second eruption, however, melted a large amount of glacial ice which then cooled and fragmented lava into gritty glass particles that were carried up with the rising volcanic plume. Pictured here during the second eruption, lightning bolts illuminate ash pouring out of the Eyjafjallajökull volcano.
How smooth is the Sun? The new Swedish 1-m Solar Telescope, deployed in the Canary Islands only last year, allows imaging of objects less than 100-km across on the Sun's surface. When pointed toward the Sun's edge, surface objects now begin to block each other, indicating true three-dimensional information. Close inspection of the image reveals much vertical information, including spectacular light-bridges rising nearly 500-km above the floor of sunspots near the top of the image. Also visible in the above false-color image are hundreds of bubbling granules, each about 1000-km across, and small bright regions known as faculas.
Watch Juno zoom past Jupiter again. NASA's robotic spacecraft Juno is continuing on its 53-day, highly-elongated orbits around our Solar System's largest planet. The featured video is from perijove 16, the sixteenth time that Juno has passed near Jupiter since it arrived in mid-2016. Each perijove passes near a slightly different part of Jupiter's cloud tops. This color-enhanced video has been digitally composed from 21 JunoCam still images, resulting in a 125-fold time-lapse. The video begins with Jupiter rising as Juno approaches from the north. As Juno reaches its closest view -- from about 3,500 kilometers over Jupiter's cloud tops -- the spacecraft captures the great planet in tremendous detail. Juno passes light zones and dark belt of clouds that circle the planet, as well as numerous swirling circular storms, many of which are larger than hurricanes on Earth. As Juno moves away, the remarkable dolphin-shaped cloud is visible. After the perijove, Jupiter recedes into the distance, now displaying the unusual clouds that appear over Jupiter's south. To get desired science data, Juno swoops so close to Jupiter that its instruments are exposed to very high levels of radiation.
