SpaceX has discontinued the planned launch of a commercial communications satellite, a Falcon 9 rocket on Friday (June 1), citing the need for additional boost stage tests
A previously flown Falcon 9 rocket was to deploy the SES-12 satellite into SpaceX's orbit at Cape Canaveral Air's Force Station in Florida Friday at 12:29 pm EDT (0429 GMT). But the mission will not appear sooner than on Monday, June 4, SpaceX officials said.
"Starting the attempt on Friday to run additional tests on the second level of Falcon 9," wrote SpaceX representatives on Twitter. "We are currently working on an introduction of SES-12 on June 4 from Pad 40 in Florida." Pad 40 is Space Launch Complex 40 at the Cape Canaveral Air Force Station.

Originally, SpaceX wanted to launch the SES-12 satellite today (May 31). But on Sunday, the company announced a one-day slip on Friday. At that time, SpaceX said its launch team had used "[the] extra time to do pre-launch vehicle checks and closely monitor the weather conditions at the Cape."
SpaceX fired the nine engines of the Falcon 9 rocket on stage last week during a static fire test on May 24. The first stage of the Falcon 9 was last used in September 2017, when it launched the robotic X-37B spacecraft for the US Air Force and then landed successfully. The booster is an older "Block 4" model (the latest version of SpaceX, the "Block 5", debuted this month) and is unlikely to land after the SES-12 mission.
The SES-12 satellite was built by Airbus Defense and Space for the Luxembourg telecommunications company SES. The satellite will provide SES customers in the Asia-Pacific region with direct-to-home video and data services, according to a mission profile.
SES-12 is destined for a geostationary orbit of 35,900 kilometers Earth. It replaces SES & nbsp; older NSS-6 satellites according to an SES description.
