An Army of Mini Satellites Will Scour Asia for Natural Disasters From Space

Natural disasters seem to be more plentiful and powerful than ever. But an alliance of Asian countries and universities is coming to the rescue. The plan is to launch a flock of small satellites to help monitor destruction as it unfolds on Earth, providing emergency responders with critical information faster than ever. Japan's Hokkaido and Tohoku Universities are teaming with a swath of Asian nations for the microsatellite project. Nikkei Asian Review reports that partners include Bangladesh, Indonesia, Malaysia, Mongolia, Myanmar, the Philippines, Thailand and Vietnam. Each nation will send a share of the microsatellites to the International Space Station, where they will be sent into orbit from Kibo, the Japanese module aboard the ISS.

The satellites are tiny: 50cm cubes that weigh about 50kg. That's 5 per cent the size of a typical satellite. These microsatellites will hang at about 500km above Earth, using cameras to photograph Earth's surface with a resolution of around 3 to 5m.

The researchers hope to have 50 of the satellites in orbit by 2020. It's no small feat, because they cost around $US2.54 million each. Apparently, it only takes 25 satellites to cover all of Asia, so if we can hit the full 50, this kind of microsatellite technology could be useful to a huge chunk of the world.
