  1. is the grey thing in between the fuel and oxidizer tanks supposed to be a payload? How is it going to be deployed in flight?
  2. looks like a hyperbola 1 lost attitude control and smashed into the gobi desert https://spacenews.com/chinas-ispace-suffers-failure-with-second-orbital-launch-attempt/
  3. more details on the cable issues below, it wasn't an issue with the cable connections themselves, it was that they were the connectors for the opposing actuators on the engine gimbal, leading to loss of attitude control. this is something that absolutely should have been caught by even the most basic preflight tests. https://spacenews.com/human-error-blamed-for-vega-launch-failure/
  4. https://www.space.com/vega-rocket-launch-anomaly-november-2020 Another Vega down, wonder if there's a future for it at this point
  5. Vector under new ownership, will be switching fuels to kerolox, and aiming to start with a suborbital vehicle https://spacenews.com/vector-restarting-operations-under-new-ownership/
  6. Sentinel is launching from Vandenberg, so they will have 3 boosters on 3 pads, somewhat difficult to pull off, but not impossible
  7. https://spacenews.com/spacex-to-explore-ways-to-provide-weather-data-to-u-s-military/ Hmm now it looks like there are plans for starlink based weather sats
  8. The ISS uses hypergolic fuel which is easier to store, but more difficult to manufacture in space. these contracts are for cryogenic fuel (LH2 or LCH4)
  9. looks like the USSF will be getting some OPIR satellites using the starlink bus https://spacenews.com/spacex-l3harris-win-space-development-agency-contracts-to-build-missile-warning-satellites/
  10. yep, bad weather on the east coast combined with already finnicky rockets
  11. the real antithesis to a flying wing is a lifting body
  12. Aviation week has been putting out a lot of articles about hydrogen propulsion, mostly for short haul regional turboprops that will be converted to fuel cell electric. For the ones that use gaseous H2, they tend to have it stored at ~300 bar, from what I understand about Hydrogen its not a matter of preventing leaks at that pressure, its about managing them. Is there any way to have that safely and still allow for the general public to board it?
  13. why have ramjets and scramjets not seen much use on manned aircraft?
  14. Looks like parts of vesta are on bennu https://www.nasa.gov/feature/goddard/2020/bennu-vesta-meteorites
