daveb Posted December 27, 2021 Share Posted December 27, 2021 5 hours ago, SorryNotSorry said: The idea of inexpensive mass emigration into outer space must surely give real estate VIPs nightmares. I wouldn't think so, since it would be total science fiction. I don't see it happening any time soon (probably not within the lifetime of anyone currently alive, or at least not anyone alive who could worry about it). 1 Quote Link to post Share on other sites

Full hemisphere animation is the next post in the thread. My country, far away from here, was hit by the tsunami, and fishing boats were turned over and damaged. I am worried about the people in Tonga. When things like this happen, it makes me realize that we live on the same planet. Unleash the Echidnas, I inadvertently misquoted you and made you feel uncomfortable. I am very sorry about that. I will be careful in the future.

Tunhope Posted February 12, 2022 Share Posted February 12, 2022 I was looking at this on BBC online a few minutes ago @Unleash the Echidnas and then I checked into AVEN. I find this stuff very exciting. Ta for the mention as I might not have seen it for all you knew. 2 Quote Link to post Share on other sites
Unleash the Echidnas Posted February 15, 2022 Share Posted February 15, 2022 Corrected identification of object about to hit the moon (March 4, 12:25 UTC) Quote Assuming no maneuvers, it would have been in a somewhat odd orbit around the earth before the lunar flyby. At its highest point, it would be near the moon's orbit; at its lowest (perigee), about a third of that distance. I'd have expected the perigee to be near the earth's surface. The perigee seemed quite high. However, rocket hardware often does strange things in its early days in space, with leftover fuel leaking out and pushing it around. That causes changes in the orbit, so that when you try to figure out where the junk came from, you get a wrong (or at least altered) answer. Such things happen routinely, but in this case, it would have required an unusual (though possible) sort of leakage, occurring several days after the lunar flyby. And it would have had to be a pretty substantial amount of leakage. 1 Quote Link to post Share on other sites
Unleash the Echidnas Posted February 18, 2022 Share Posted February 18, 2022 A Himawari-8 to GOES-17 parallax analysis with shadow confirmation. The underlying remote sensing maths are entirely routine but it's somewhat unusual to have something of interest that's tall enough to measure its height from geosynchronous orbit. Tonga Volcano Plume Reached the Mesosphere Quote Scientists at NASA’s Langley Research Center analyzed data from NOAA’s Geostationary Operational Environmental Satellite 17 (GOES-17) and the Japanese Aerospace Exploration Agency’s (JAXA) Himawari-8, which both operate in geostationary orbit and carry very similar imaging instruments. The team calculated that the plume from the January 15 volcanic eruption rose to 58 kilometers (36 miles) at its highest point. Gas, steam, and ash from the volcano reached the mesosphere, the third layer of the atmosphere. 1 Quote Link to post Share on other sites
SorryNotSorry Posted March 10, 2022 Share Posted March 10, 2022 When I think about migrating into space, I don’t think of conquest or planting a flag on someone else’s planet. Far from it. I think of getting off this ass-backwards planet and never having to deal with other humans again. Quote Link to post Share on other sites

Skyfighter Posted September 30, 2022 Share Posted September 30, 2022 Nasa received four more RS-25 engines for Artemis 2's core stage. Looks like November 12th now by the time they replace batteries on the FTS and other stuff and roll it back out for Artemis 1 i mean the Cryogenic Demonstration Test went alright last time so hopefully we can see it launch and hopefully the leak doesn't show up next time. But there's another launch on October 5th with Crew 5. Crew Arrived at KSC today (1/10/22) 2 Quote Link to post Share on other sites
Skyfighter Posted October 5, 2022 Share Posted October 5, 2022 Crew 5 Launch Day! Broadcast starts at 13:30BST (08:30am ET), Launch Scheduled for 5:00pm BST (12pm ET) hopefully they launch today, Weather showing <10% no go. https://youtu.be/5EwW8ZkArL4 Quote Link to post Share on other sites

Next Event: In Distant Retrograde Orbit (DRO) - DRO Departure Burn (December 1st - 21:53UTC) Orion also eclipsed Apollo 13's record for the farthest distance travelled away from earth by a spacecraft designed for humans. https://twitter.com/JimFree/status/1595441181265203201?t=9PllFfzG-0Z3b4dkLYmWYA&s=19 "Overnight on Wednesday they unexpectedly lost Comms with Orion when reconfiguring a link between it and the DSN" Link was restored so that's good (Credit to https://twitter.com/NASAGroundSys/status/1593330425388322816/photo/1 for photo) and then there was some issues during the launch count but after all the issues with sls on the dress down tests and previous launch attempts they finally did it, i mean they did need to send a team down to the pad to think a leak or something There was also some damage to the pad after the launch for example the shock wave caused by SLS ripped off two of the doors for the lifts, there was damage to the pneumatic lines for the gaseous nitrogen and gaseous helium which service the sls tanks. That just shows how powerful SLS is If you want to track Orion: https://www.nasa.gov/specials/trackartemis/ 2 Quote Link to post Share on other sites
