(2). The ROSA is very much flexible so that it can be adapted to different sizes including very large arrays.
(3). ROSA is expected to provide power for a variety of future spacecraft and satellites.
(4). 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.
(5). ROSA with significantly less mass and volume can offer substantial cost savings and increase the power for satellites.
(6). Why in news? It is being tested on International Space Station.
