EDITOR\u2019S NOTE: Updated Jan. 7 for new launch date and launch pad.<\/strong><\/p>\n

SpaceX\u2019s next Falcon 9 booster is being readied for liftoff from Cape Canaveral, but most of the launcher\u2019s ascent into orbit will be under a news blackout at the request of the U.S. government customer that owns the top secret Zuma payload fastened to the top of the rocket.<\/p>\n

The 229-foot-tall (70-meter) rocket is poised for launch from pad 40 at Cape Canaveral Air Force Station in Florida.<\/p>\n

The timeline of upper stage events after the release of the rocket\u2019s payload fairing, scheduled for T+plus 3 minutes, 8 seconds, has not been released. SpaceX\u2019s live coverage of the second stage\u2019s progress is expected to conclude at that point of the mission.<\/p>\n

Meanwhile, the rocket\u2019s first stage booster will flip around with the aid of cold gas thrusters, then reignite a subset of its engines for re-entry and landing burns, aiming for a vertical touchdown at Landing Zone 1 at Cape Canaveral Air Force Station, around 6 miles (9 kilometers) south of pad 40.<\/p>\n

\"The
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. The rest of the rocket\u2019s ascent into orbit will not be broadcast by SpaceX at the customer\u2019s request, and further details about the mission timeline have not been released.<\/figcaption><\/figure>\n

T+0:06:15: Stage 1 Entry Burn<\/b><\/p>\n
