Yes, you can help save the world. And just by downloading some free software. Writes NASA:
Protecting the Earth from the threat of asteroid impacts means first knowing where they are. NASA is harnessing the incredible potential of innovators, makers and citizen scientists by opening up the search. In an increasingly connected world, NASA recognizes the value of the public as a partner in addressing some of the country’s most pressing challenges. We need your help in identifying asteroids – and to help further this effort, we’ve built an application that enables everyone, everywhere, to help solve this global challenge.
Next up? Hopefully an app that saves California, which, a NASA official projects, will run out of water by next year.
