NASA Wraps Up Ontario Snow Observing Research Campaign

For six weeks in Ontario, NASA scientists and engineers lead a field campaign to study the science and mechanics of falling snow. The datasets retrieved will be used to generate algorithms which translate what the Global Precipitation Measurement (GPM) Core satellite “sees” into precipitation rates, including that of falling snow. Ground validation science manager Walt Petersen gives a summary of the GCPEx field campaign. Field …

Dextre makes the cut: Wire Cutting task is a resounding success! Part 2

Day 2 of the initial phase of the joint NASA-CSA Robotic Refueling Mission (RRM) ended with a historic moment for Dextre, the Canadian-built robotic handyman on board the International Space Station (ISS). Dextre spent the better part of the day successfully releasing 7 launch locks that fastened 4 tool adapters (built by NASA’s Goddard Space Flight Center) inside the RRM module during their flight to …

Dextre makes the cut: Wire Cutting task is a resounding success!

After completing operations with the Multifunction Tool, Canadarm2 repositioned Dextre to cut the first of two wires, each about as thick as four sheets of paper. With surgical precision, and only about a millimetre of clearance, Dextre captured the wire in the Wire-Cutting Tool (1:14-1:32). The Canadian-built robotic handyman then cut the thin wire (1:44-2:03) that fastened a mock gas cap to the RRM module …
