Jason-3, Falcon 9 Aim for Launch Today

At Space Launch Complex 4 at Vandenberg Air Force Base in California, a SpaceX Falcon 9 rocket stands ready to boost the Jason-3 spacecraftEarth’s oceans could have a new observer in orbit just a few hours from now.

Countdown clocks are ticking steadily down toward the planned launch of the Jason-3 satellite aboard a SpaceX Falcon 9 rocket from Vandenberg Air Force Base in California. Liftoff from Space Launch Complex 4 is slated for 10:42:18 a.m. PST / 1:42:18 p.m. EST at the start of a 30-second launch window.

Launch Weather Officer Lt. Joseph Round of the 30th Operations Support Squadron at Vandenberg predicts a rare 100 percent chance of favorable conditions during the countdown and liftoff.

The product of an international partnership, Jason-3 will measure the topography — the “hills and valleys” — of Earth’s oceans, generating data for use in weather modeling, seasonal and tropical storm forecasting, the maritime safety community and research. The Jason-3 mission enhances our ability to monitor Earth right now, using the vantage point of space to increase our understanding of our home planet, improve lives and safeguard our future.
