Answer

Brief Explanations:

  1. For the problem of spacecraft exposing astronauts to dangerous radiation, the solution is that NASA may equip ships with special habitats as they can offer a defensive shield against radiation.
  2. For the problem of spacecraft not being able to refuel in deep - space, the solution is that spacecraft may draw energy from the sun as it allows ships to refuel without nearby space stations.
  3. For the problem of large spacecraft being difficult to land safely, the solution is that spacecraft can use supersonic retropropulsion as it helps spacecraft land on Mars' surface without crashing.

Answer:

Spacecraft expose astronauts to dangerous levels of radiation - NASA may equip ships with special habitats. Spacecraft cannot refuel in deep space - Spacecraft may draw energy from the sun. Large spacecraft are difficult to land safely - Spacecraft can use supersonic retropropulsion.
