BetaguyGZT Posted September 1, 2018 Author Share Posted September 1, 2018 WHOA. So a defect in manufacturing which then failed ... and said defect should have never occurred in the first place. WHAT THE ****. That kind of defect just doesn't happen. Not even in Russia. Nobody is that careless. NASA is gonna pull our people for sure now. A defect like this can and will cause explosive decompression events if there are other engineering/design defects. Any Engineer worth their salt knows how to work down a fault tree.

DocM Posted September 5, 2018 Share Posted September 5, 2018 (edited) DARPA Blackjack: DoD pivot to LEO satellite constellations Leveraging large LEO constellations and techs (SpaceX's StarLink, OneWeb) for DoD purposes Given the USAF interest, and recent test programs, for using SpaceX's StarLink for military aircraft comms, this sounds way more serious than most DARPA projects. Pages 4 & 5 pf the presentation show a Falcon 9 launch vehicle. Interview with Blackjack Program Manager Paul "Rusty" Thomas, formerly of SpaceX (Senior Director, Dragon Production) https://www.c4isrnet.com/thought-leadership/2018/07/30/the-calculus-of-cheaper-military-comms-satellites/ Quote Thomas: Blackjack is aimed at leveraging the new mesh networks being set up by these commercial companies. A user currently in the DoD might need to look up at two or three different options in space to actually talk and do communications in this space segment. Once we link up and do encryption, the user on the ground will look up and see hundreds or more potential network nodes overhead at any given point on the planet, North Pole to South Pole; it’s going to drastically change how the DoD does communication. That is a bit independent of what Blackjack is going to do. If the commercial companies succeed and come out, that capability, call it raw gigabit-per-second class, not all of them it. But they all have many megabit data links from one point of the planet to another, at very low latency, 100-200 milliseconds, so you do really change the game for how any user, DoD included, does global communication.

Draggendrop Veteran Posted September 11, 2018 Veteran Share Posted September 11, 2018 India Unveils Its Own Spacesuit Design for 2022 Astronaut Flights Quote The Indian Space Research Organisation showed off the spacesuit it has designed in-house for its first human space missions at an event held on Sept. 6. The display comes weeks after the country announced an ambitious timeline to launch its first crewed mission by 2022 in time to commemorate the 75th anniversary of the country's independence. The human-spaceflight program is called Gaganyaan and will build on the legacy of India's first astronaut, Rakesh Sharma, who flew in 1984. But this time, India is developing every aspect of the program, which means tackling problems like spacesuit design. https://www.space.com/41774-india-unveils-spacesuit-design-gagayaan-2022.html?utm_source=twitter&utm_medium=social Link to comment https://www.neowin.net/forum/topic/1334452-general-space-discussion-thread-1/page/10/#findComment-598346312 Share on other sites More sharing options...
DocM Posted September 12, 2018 Share Posted September 12, 2018 (edited) Farewell, Delta II !! What a workhorse, and still launched by an 'ugly bag of mostly water' pressing a console button. There's one more in storage, currently spare parts for this mission but likely headed for a museum after the ICESat-2 launch. NASA's ICESat-2; observations of ice-sheet elevation change, sea-ice freeboard, and vegetation canopy height.

Draggendrop Veteran Posted September 13, 2018 Veteran Share Posted September 13, 2018 We know SpaceX and Blue Origin are in full reusable mode. China is also slowly adapting to this. Look familiar.... China's latest satellite launch used a parafoil to limit damage downrange Quote China tested the use of a parafoil on the payload fairing of its latest orbital launch last Friday, with the aim of improving accuracy of its return to Earth and potentially eventual reusability. The launch of the Haiyang-1C marine observation satellite took place at the Taiyuan Satellite Launch Centre in north China, with a Long March 2C rocket successfully placing the satellite into a 770 x 786 km altitude orbit inclined by 98.6 degrees. China's traditional satellite launch sites are situated deep inland, due in main to the security concerns raised by the ongoing Cold War and Sino-Soviet split. This means discarded stages, boosters and payload fairings often fall to ground - sometimes in inhabited areas - instead of the oceans, as with US and European launches. Following and inspired by the successes of SpaceX and Blue Origin in launching and landing and, in this case, attempting to recover payloads, the China Aerospace Science and Technology Corporation (CASC), the main space programme contractor, is seeking to bring similar technology to bear on its own launch vehicles. https://gbtimes.com/chinas-latest-satellite-launch-used-a-parafoil-to-limit-damage-downrange [youtube] ?
