Built with spare change, spare parts and without a moment to spare, RapidScat isn’t your average NASA climate mission.

It's a new instrument from NASA that will measure ocean winds from the vantage point of the International Space Station. Launching into Earth orbit in spring 2014, RapidScat will hitch a ride on the back of a SpaceX rocket, and will continue NASA's legacy of monitoring ocean winds, weather systems, hurricanes, and climate patterns as they evolve.

The story behind the mission is covered in our new feature here. When a previous wind monitoring instrument came to an end in 2009, scientists were tasked with cobbling together a quick replacement. RapidScat, with a price tag of "just" $26 million (a bargain relative to the usual $200 million or so), fits that bill. It also falls in line with NASA's push to come up with cheaper Earth observing missions (be they ones that operate from aircraft or from space) and to harness the power and agility of rocket companies such as SpaceX.
