SpaceX launched a Falcon 9 rocket from Vandenberg Air Force Base in California, containing the Canadian Space Agency's Radarsat trio of Earth observation satellites on Wednesday.

The broadcast was telecast live on SpaceX's YouTube channel and it was a particularly interesting one -- the base was covered in fog.

That provided a wonderful image of the Falcon 9 bursting through the layer of fog as it ascended to orbit (above).

It also provided an interesting landing for the Falcon 9 booster as it returned to land at Vandenberg shortly after separation.

If you missed it as it happened, you can watch a replay of the launch below.

Canada's three Radarsat satellites, shaped like old rubber stamps, will gather data about the nation's coasts and waterways to help ships navigate the Arctic, provide agriculture solutions and help first responders save lives, according to the agency.
