Hrs right after contacting off a launch of a distinct rocket from a nearby launch pad, SpaceX’s start staff loaded a Falcon 9 rocket with propellant Saturday and fired its 9 most important engines on pad 40 at Cape Canaveral Air Power Station, location the stage for a liftoff with a South Korean armed service satellite as shortly as Tuesday amid a hectic stretch of missions for the California-primarily based rocket corporation.

SpaceX floor crews elevated the Falcon 9 rocket vertical on pad 40 Saturday morning. An automatic computer system-managed sequencer commanded super-chilled, densified kerosene and liquid oxygen into the Falcon 9 Saturday afternoon.

The countdown culminated in ignition of the rocket’s 9 Merlin 1D most important engines at 6 p.m. EDT (2200 GMT). The engines throttled up to total electric power, creating 1.7 million kilos of thrust for a number of seconds while clamps restrained the Falcon 9 on the launch pad.

Onlookers observed a plume of exhaust coming from the rocket and confirmed the the check-firing occurred. SpaceX was anticipated to formally launch an update on the end result of the static fireplace take a look at immediately after a quick-glimpse facts review.

The Falcon 9 will be reduced and rolled back again within SpaceX’s hangar in close proximity to pad 40, the place experts will connect a European-created communications satellite named Anasis 2 built for the South Korean navy.

Assuming the final times of start preparations go in accordance to strategy, SpaceX programs to start the mission Tuesday for the duration of a virtually 4-hour window opening at 5 p.m. EDT (2100 GMT) and extending until eventually 8:55 p.m. EDT (0055 GMT).

The static hearth test Saturday for the Anasis 2 mission transpired the similar day SpaceX planned to launch a Falcon 9 rocket from pad 39A at NASA’s Kennedy Space Middle, positioned a couple miles north of pad 40. SpaceX declared Saturday early morning that it termed off the launch from pad 39A “to permit more time for checkouts.”

SpaceX tweeted that teams “working to establish the next start opportunity” for the mission from pad 39A, which will loft SpaceX’s next 57 Starlink broadband Online satellites and a pair of business BlackSky Earth-imaging microsatellites.

The Starlink/BlackSky start was meant to acquire off June 26, but SpaceX delayed the mission to carry out further pre-start checkouts. A start endeavor Wednesday was scrubbed minutes prior to liftoff by very poor climate.

The organization has not disclosed any aspects about the nature of the complications — other than climate — that have delayed the Starlink/BlackSky mission. As of Saturday night, it was not crystal clear no matter if SpaceX may well proceed with Tuesday’s planned Anasis 2 start up coming, or if there may possibly be a further opportunity to launch the Starlink/BlackSky mission as before long as Monday.

SpaceX has released 11 Falcon 9 missions so significantly this yr, most a short while ago on June 30, when a Falcon 9 rocket took off from pad 40 with a U.S. military GPS navigation satellite.

Produced by Airbus Protection and House, the Anasis 2 satellite is shrouded in secrecy at the wishes of the the spacecraft’s owner — the South Korean authorities.

Anasis 2 is based on the Eurostar E3000 spacecraft platform designed by Airbus, but information about its general performance have been saved beneath wraps. The Anasis 2 satellite is predicted to launch into an elliptical transfer orbit, then use its on-board propulsion method to reach a circular orbit at geostationary altitude a lot more than 22,000 miles (approximately 36,000 kilometers) more than the equator.,

South Korea ordered the satellite — previously regarded as KMilSatCom 1 — as a result of an arrangement to offset South Korea’s purchase of F-35A fighter jets from Lockheed Martin. Lockheed Martin ultimately subcontracted the satellite producing offer to Airbus.

Just before Anasis 2, South Korea’s military has relied on intercontinental and civilian-owned satellites for communications.
