Launch timeline for Falcon 9/Jason 3 mission

Follow the key events of the Falcon 9 rocket’s ascent to orbit with the Jason 3 satellite, a joint project between European and U.S. weather agencies to monitor wave height and sea level in the world’s oceans.

The 224-foot-tall rocket will lift off Sunday at 10:42:18 a.m. PST (1:42:18 p.m. EST; 1842:18 GMT) from Vandenberg Air Force Base in California.

T+0:03:15: Fairing Jettison

The 5.2-meter (17.1-foot) diameter payload fairing jettisons once the Falcon 9 rocket ascends through the dense lower atmosphere. The 43-foot-tall fairing is made of two clamshell-like halves composed of carbon fiber with an aluminum honeycomb core.

T+1:02:00: Jason 3 Solar Arrays Deployed

Jason 3's two solar array wings will deploy one at a time starting about two minutes after separation from the Falcon 9 second stage. Both wings should be extended by the flight's 62-minute mark.
