Nasa has offered its support and expertise in the search for missing Malaysian Airlines flight MH370.
The American space agency said that it would examine ways it could contribute to the search, which is also being aided by the work of 25,000 online volunteers.
Flight MH 370 disappeared last week, and the fate of all 239 people on board is unknown. The exact position of the aircraft before it's apparent demise is unclear, and investigators say that without access to the plane's emergency recording systems, it will be impossible to say for sure what caused it.
Nasa said that it will offer images taken using its satellites and cameras on board the International Space Station, which could identify objects larger than 30 metres.

"Activities under way include mining data archives of satellite data acquired earlier and using space-based assets, such as the Earth-Observing-1(EO-1) satellite and the ISERV camera on the International Space Station, to acquire new images of possible crash sites," NASA spokesman Allard Beutel told Space.com.
"The resolution of images from these instruments could be used to identify objects of about 98 feet (30 meters) or larger."
Nasa will also send data to the US Geological Survey's Earth Resources Observations and Science Hazard Data Distribution System, which helps share data under the International Charter on Space and Major Disasters (which was also activated after the recent floods in Britain).
