Space-X Blasts Off Sports Car-Sized Satellites To Measure Earth's Water

A SpaceX Falcon 9 rocket lifts off from Space Launch Complex 4E at Vandenberg Air Force Base.

Washington, United States: A SpaceX rocket Tuesday blasted off a duo of sports car-sized satellites built by the US and Germany to reveal changes in sea level rise, ice melt and drought on Earth.

"Three, two, one, liftoff!" said a SpaceX commentator as the Falcon 9 rocket launched from Vandenberg Air Force Base in California at 12:47 pm Pacific time (1947 GMT).

The $521 million payload is called the Gravity Recovery and Climate Experiment Follow-on (GRACE-FO).

It picks up from GRACE, a satellite pair that launched in 2002 and tracked, among other things, precisely how much ice was lost each year in Greenland and Antarctica until 2017.

Groundwater, oceans, lakes, rivers and ice sheets will be monitored by the twin satellites, a joint mission between the US space agency and German Research Centre for Geosciences (GFZ).

The pair will fly 137 miles (220 kilometers) apart, or about the distance from Los Angeles to San Diego.
