Space blankets and How the TeamIndus spacecraft will survive in space

A look at multi-layer insulation and how we use it

Difficulties of managing heat in space

  • Electric power onboard the spacecraft is too limited to make use of heaters excessively.
  • The environmental conditions can drastically vary depending on the mission phase, making it difficult for one solution to adapt to all needs.

#3: Why not just use a thick block shield instead?

#4: Protection from impacts

Use of MLI on the TeamIndus spacecraft
