Apparently parachutes are still an issue for certification, per NASA safety panel, they are skeptical about July launch date and overall readiness for flight https://spacenews.com/nasa-safety-panel-skeptical-of-starliner-readiness-for-crewed-flight/

depends on whether it would cold weld shut or not

I cant take that article seriously, I have yet to see enough capital, skilled workers, or political will to get a functioning space program, at best we will see some scientific payloads and small satelites, but there just isnt the kind of manufacturing base for large spacecraft or mass produced spacecraft.

There is a startup that plans to air launch a small-sat launcher from the back of a C-17 based out of Glasgow. Details are sparse but they say they plan to use a Northrup Grumman Orion (family of motors that fly on the Pegasus rocket) first and second stage and an in house third stage. The wording suggests it is solid fueled. https://www.astraius.com/2022/07/farnborough-announcement/ https://simpleflying.com/astraius-preswtick-airport-c-17-rocket-launch-update/ curious to see how they plan to get around the cost issue Pegasus has, wonder how much is related to running a unique aircraft and will they be able to rent any C-17 or have to specially modify it?

looks like they had a special guest at the launch https://imgur.com/hRh76aw https://futurism.com/the-byte/strange-creature-juice

Considering Pluto already has a twin and several moons I doubt that it has lost a member of its system to Neptune

Launching a rocket from underwater is pretty much a solved problem at this point nearly every navy with submarines can do it and the russians have even put a couple payloads into orbit from a submarine a few times https://en.wikipedia.org/wiki/Shtil'

keep in mind we dont know how far away the microphone is from the event, and how in sync the audio is, we could be seeing a bit before we hear, best not to jump to any conclusions yet -
Magnetic Cold Gas Rocketry... What If?
insert_name replied to Spacescifi's topic in Science & Spaceflight
what is this magnetic gas you speak of, and why would it perform better than hot non-magnetic gas or ion engines? -

How do I create a spacecraft trajectory in Desmos?

use Kepler's equation, most likely the hyperbolic anomaly version of it https://en.wikipedia.org/wiki/Kepler's_equation -
Looks like Vega C failed, not a good look for the Vega family, at least the launch commentators realized something was wrong, but it was interesting seeing the animations go like the mission was nominal long after the failure https://spaceflightnow.com/2022/12/21/two-pleiades-neo-earth-imaging-satellites-lost-in-failure-of-europes-vega-c-rocket/

final poll is still no go for upper level winds, looks like a scrub
-
22 minutes until window close, will either launch or hold if things get worse on the upper level winds front
-
In a hold until upper level winds calm down

The Power Of Cell Phones In War...

The issue with jamming is that it works both ways, and this could end up limiting drone use and internal communications
