totm nov 2023 SpaceX Discussion Thread
insert_name replied to Skylon's topic in Science & Spaceflight
SpaceX got another X-37b launch, this time on falcon heavy, wonder why they are using it instead of regular falcon https://spacenews.com/u-s-air-force-x-37b-spaceplane-to-launch-on-a-spacex-falcon-heavy-rocket/ -
Lucy has flown by Dinkinesh, NASA has received communications from the spacecraft, but I cant find any pictures yet, probably gonna take a while for them to download with the light lag https://blogs.nasa.gov/lucy/2023/11/01/nasas-lucy-spacecraft-completes-asteroid-flyby/

totm dec 2019 Russian Launch and Mission Thread
insert_name replied to tater's topic in Science & Spaceflight
Yeah the only way I actually see this being a practical idea is if the new reentry vehicle they cobble together on top of a platform wholly unsuitable for ICBM work is somehow more reliable than whatever ballistic missiles they have lying around, maybe if the private in charge of maintenance decides to get into the scrap copper business, though I don't think a Soyuz would fare much better against that -

Sounds like the Soyuz may be returning to it's ICBM roots soon, not sure that this is going to work too well without a new reentry vehicle, and even then this won't be that accurate https://www.newsweek.com/putin-roscosmos-bild-rogozin-rocket-soyuz-1837809 -
yeah maybe, but I don't think there are many missions worth using an RTG on where you would use a cheap ESPA ring bus instead of a custom design, not to mention the thermal control, micrometeoroids, radiation hardening, and the rather scarce nature of ground stations that can reach that far

They said that this thing can go interplanetary, and even interstellar in the aviation week article. Think that might be overpromising a bit much?

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?
