Satellites in the developing world (MIT)
Within 24 hours of the catastrophic 2010 earthquake near Port-au-Prince,
Haiti, space agencies and companies around the world tasked satellites with

satellite operators around the world offer to share satellite data after a
natural or man-made disaster. But now, a number of developing countries are
taking steps to build their own national satellite programs, seeking more
control over remote-sensing data to map and forecast disasters, monitor crop
yields and track environmentally driven diseases such as malaria.
In a paper published recently in the journal _Acta Astronautica_, Danielle

systems at MIT, examine countries including Nigeria, Malaysia and Thailand
