The Gulfstream V took off from Mineta San Jose International Airport yesterday packed with Nasa scientists and their equipment.
A 10-hour flight to the Arctic and back allowed the boffins to study the Quadrantids meteor shower currently hitting Earth.
At its peak the Quadrantids send 100 meteors an hour into the atmosphere, where they burn up and fall to Earth.
The trip was part of a special deal that Google has arranged with Nasa, which provoked some controversy in Silicon Valley.
Under the deal Google can park its three corporate jets at Nasa's Moffett Field which is officially closed to civilian air traffic.
However, it is just four miles from Google's headquarters so the company allows the jets to be used for scientific experiments by Nasa in exchange for parking space.
