NASA rsquo s ROSA is expected to 1 Detect asteroid clashes in outerspace 2 Power satellites and spac...........

Explanation:

NASA is testing the effectiveness of a flexible solar array, the Roll-Out Solar Array, or ROSA, on space station for the very first time. It was tested on earth earlier.

It rolls out like a tape measure.

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.

Application: ROSA is expected to provide power for a variety of future spacecraft and satellites.

It will be an asset for satellite radio and television, weather forecasting, GPS and other services used on the Earth.

The NASA engineers remotely attached the ROSA to the International Space Station’s robotic Canadarm2. ROSA will remain attached to the Canadarm2 over seven days to test its effectiveness.

Scientists will test the effectiveness of ROSA in the microgravity and extreme temperatures of space.
