    Apollo Helium
AI Thread Summary
Helium tanks in the Apollo Command Module were utilized to feed propellant for the attitude control system and the main engine. These tanks were part of the Command Module's reaction control subsystem. Attitude control thrusters were essential for re-entry, especially after the Service Module was jettisoned. The discussion highlights the importance of helium in managing spacecraft orientation during critical phases of the mission. Understanding these components is crucial for comprehending the Apollo program's engineering.

TL;DR Summary
Why were there tanks of helium on the CM?
Hello All

Diagrams of the Apollo Command Module show tanks of helium, What was this used for?

best regards ... Stef

I think it was used to feed propellent for attitude control and perhaps the big engine. Were these in the Service module or the command module?
 
Of course you would still need attitude control thrusters for re-entry (after ejecting the Service module). Duh I didn't even think it through.
 

Thread 'Radiation Hard Electronic Design for LVO Long Mission'

Venus does not have a magnetosphere, so the Galactic Cosmic Rays (GCRs) environment shall be much worse than in a LEO environment. Looking to the std radiation models for Venus, the standard radiation-hard space level electronic component with tested immunity LET = 85 MeV-cm2/mg seems not enough, so, for example, a 1cm2 Si die will suffer considerable flux above this level during a long mission (10 years for example). So, the question is, usually we are not paying attention to latch-up...

Thread 'Space Stuff and Launch Info'

Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile: https://blogs.nasa.gov/spacex/

Thread 'SpaceX Starship development: 7th flight January 10'

Watch the progress live This is a fully stacked Starship (top) and Super Heavy (bottom). A couple of too-small-to-see cars near the bottom for scale, I also added a Saturn V and the Statue of Liberty for comparison. 120 meters tall, about 5000 tonnes when fully fueled. Twice the mass and over twice the thrust of Saturn V. The largest rocket ever built by mass, thrust, height, and payload capacity. N1 had the largest diameter.[/size] But its size is not the revolutionary part. It is designed...
