Helium pressurant also flowed into the rocket in the last half-hour of the countdown. The SpaceX launch team working in a control center just outside the gate of Cape Canaveral Space Force Station began loading super-chilled, densified kerosene and liquid oxygen propellants into the Falcon 9 vehicle at T-minus 35 minutes.

That mission was supposed to launch just 35 minutes before the OneWeb mission from Cape Canaveral, but has now been rescheduled for liftoff Tuesday night. SpaceX delayed the launch of a different Falcon 9 rocket from Vandenberg Space Force Base in California Monday night due to bad weather. The launcher thundered into the sky on the power of 1.7 million pounds of thrust from nine kerosene-fueled Merlin main engines, kicking off SpaceX’s second mission of the year. The 229-foot-tall (70-meter) Falcon 9 rocket lifted off from pad 40 at Cape Canaveral Space Force Station at 11:50:17 p.m. The Falcon 9 booster returned to Cape Canaveral for landing eight minutes later. All of those dates, as ever in the launch business, are subject to change.A SpaceX Falcon 9 rocket lifted off from Cape Canaveral Monday night with 40 more internet satellites for OneWeb, nudging the network closer to full operational capability. Trevor Mahlmann will be on hand for Ars to provide unique views of this large launch vehicle.įuture Falcon Heavy missions this year include a commercial mission for the satellite communications company ViaSat in March, the Space Force's USSF-52 mission in April, a commercial mission for EchoStar in May, and the Psyche asteroid mission for NASA in October. This will be the first time that the Falcon Heavy rocket has launched in twilight, and it should be visible for hundreds of kilometers up and down the Florida coast. The timing for this launch is noteworthy, as the launch window opens just 10 minutes after sunset. Weather conditions are favorable for the launch attempt. The launch is scheduled for 5:55 pm ET (22:55 UTC) from Launch Complex 39A at Kennedy Space Center. SpaceX will again attempt to recover these side boosters at its land-based landing zones for a future mission. The rocket will use a brand new core stage and side-mounted boosters that have been flown into space one time (as side-mounted boosters on the USSF-44 Falcon Heavy mission that launched on Nov. SpaceX completed a hot fire test of the rocket on Tuesday, and declared that the vehicle was ready for liftoff. Stephen Purdy, program executive officer for Assured Access to Space, said in a news release. ![]() "This is a complex mission and truly represents what Assured Access to Space is about and is why we ’re so enthusiastic about this upcoming launch," Maj. Among these five payloads is a prototype "crypto/interface encryption" satellite that will deliver secure space-to-ground communications capability. The second payload, called Long Duration Propulsive ESPA-3A, is actually a spacecraft "bus." It will host five different, smaller payloads and provide power and propulsion before dropping these vehicles into various orbits. This is essentially a communications relay satellite, which the Space Force says will support operations by augmenting "existing military satellite communication capabilities and continuously broadcast military data through space-based satellite relay links."

This will be the second Falcon Heavy mission for the US Space Force, and the rocket will be carrying two payloads into geostationary orbit. ![]() ![]() As early as Saturday, from Florida, the first of potentially five launches of the heavy lift rocket this year could take place.įirst up is the USSF-67 mission. However the main reason for the low cadence has been due to a lack of readiness of payloads for the new rocket, particularly from the US Department of Defense.īut now this trickle of Falcon Heavy launches may turn into a flood. Another factor is that SpaceX has increased the performance of its Falcon 9 rocket so much that it can complete a lot of the missions originally manifested on the Falcon Heavy. Why? It's partly because there is simply not all that much demand for a heavy lift rocket. Since then, however, SpaceX's heavy lift rocket has flown just three additional times. Original post: Nearly five years have passed since the massive Falcon Heavy rocket made its successful debut launch in February 2018.
