Roll-Out Solar Array, or ROSA

  • ROSA is an advanced, flexible solar array that rolls out like a tape.
  • The ROSA is very much flexible so that it can be adapted to different sizes including very large arrays.
  • ROSA is expected to provide power for a variety of future spacecraft and satellites.
  • ROSA is smaller and lighter than the traditional panels and has a centre wing build of a flexible material containing photovoltaic cells to convert light into electricity.
  • ROSA with significantly less mass and volume can offer substantial cost savings and increase the power for satellites.
  • Why in news? It is being tested on International Space Station.
