When a #spacecraft is launched from #Earth 🌍, its forward #velocity combined with the gravitational pull of Earth cause it to travel in a curved path. As the spacecraft heads toward another #planet 🪐, the #gravitational pull of that planet factors in to the path the spacecraft takes. https://www.jpl.nasa.gov/edu/teach/activity/lets-go-to-mars-calculating-launch-windows

The spacecraft departs #Earth 🌍 at a #speed of about 39,600 kph. The trip to #Mars will take about seven months and about 480 million kilometers https://mars.nasa.gov/mars2020/timeline/cruise

The #SLS and #Orion spacecraft projects are of such a scale that they spend money in all 50 states and Puerto Rico, creating #parochial interest in nearly every congressional district. It sounds like a straightforward argument: cancel the slow and outdated SLS and direct its $2.6 billion 💰 per year into novel public-private partnerships like #SpaceX’s #Starship https://www.planetary.org/articles/why-we-have-the-sls

#NASA found that protective “char layer” material from the heat shield wore away unexpectedly during reentry in more than 100 locations. The material cracked and broke off the #spacecraft in pieces, creating a trail of debris, instead of melting away as it was supposed to. The spacecraft heats 🔥 up to 5,000 degrees Fahrenheit during reentry—about half as hot as the surface of the sun ☀️. Some bolts on Orion also unexpectedly melted and eroded. https://www.smithsonianmag.com/smart-news/nasas-orion-capsule-heat-shield-wore-away-in-more-than-100-places-during-2022-test-flight-posing-significant-risks-180984296/

#Astronauts 👨‍🚀 travelling to #Mars would encounter #radiation ☢️ levels higher than humans have ever experienced, and be exposed to them for much longer.

To protect them, the #spacecraft would either have to be much bulkier, making launches expensive and difficult, or be made of more efficient #shielding 🛡️ materials. https://www.skyatnightmagazine.com/space-missions/how-will-humans-survive-the-journey-to-mars

🤔 Why isn't the #ISS (partially) recycled (by #SpaceRobot) and parts ⚙️ or raw material used for the #LunarGateway (maybe for #RadiationProtection instead of #luggage 🛍️)? The #BBC article doesn't cover this https://www.sciencefocus.com/news/why-is-the-iss-being-retired-and-what-will-happen-to-it

The #LaunchCost 💰 were very high to bring this material to #orbit 🚀 https://en.wikipedia.org/wiki/International_Space_Station

To safely bring the #ISS back to #Earth, a dedicated #spacecraft will have to be built, the total cost of which is estimated at $1 billion 💰 over the course of this decade.
A #SpacePolicy expert suggested the opposite idea: #raising ⤴️ the #ISS to a stable #orbit at the end of its useful life ♻️ https://english.elpais.com/science-tech/2023-11-20/25-years-of-the-international-space-station-what-next-for-a-beacon-of-peaceful-international-scientific-collaboration.html

"...a power outage at #SpaceX’s California facility caused a loss of #GroundControl, meaning that the mission control team was briefly unable to command the #spacecraft."

Single outage brought GROUND CONTROL down?! On the ground where power grids & diesel generators at a nearby home improvement store are! Have they never heard of battery backups and generators?! They have no idea what 3 points-safe₁ means, nor failover₂, and have no business trying to send so much as a spatula to #space.

Hopefully this won’t change our mission to the ISS to study the effects of zero gravity on crown tapper and wearability.
