I have a humanoid individual who for various reasons finds themselves in low orbit 💫 with no ship or shuttle 🚀 or tech to take them down
The society they come from is about renaissance era level (but there are lost and hidden caches of far-future type knowledge - so I can get my individual to accidently find any of the required info).
What is the absolute minimum sort of facts that this person will need to know beforehand, to survive re-entry and the fall from low-orbit?
They have an oxygen supply and an advanced handwavium designed pressure-protection body-encasing substance. This substance can reflect heat, so I don't see any issues from re-entry itself(if re-entry is even an issue). This substance may possibly be suitable to propel small distances by directing the oxygen supply like retro-rockets. The substance can be altered in a short time to any basic shape the individual would require.
I will edit further if more clarification is needed.
