SpaceX launched another Falcon 9 rocket from Cape Canaveral early Sunday morning. The rocket puts the SiriusXM-8 radio satellite in orbit and relays entertainment programming to receivers in cars, boats, homes and offices.
The previous Maxar satellite in the series, the SXM-7, failed a few weeks after it was launched on another Falcon 9 last December. However, the two older relay stations are still fully functional and SiriusXM will build a replacement for the failed relay station.
The latest mission began at 12:26 EST, with Falcon 9 on Pad 40 at Cape Canaveral Space Force Station starting nine first-stage engines and roaring a 229-foot-high rocket. I pushed it up into the night sky. A jet of intense exhaust. For the company, this was the 18th Falcon 9 flight so far this year, and the 121st flight overall.
The first stage of the rocket, which ascends the Atlantic Ocean eastward with a thrust of 1.7 million pounds, made its third flight, unfolding a familiar yet dramatic show for miles of Florida’s Space Coast. I did.
Two and a half minutes after takeoff, the first stage engine shut down, the stage fell, and the flight continued with the power of a single vacuum-rated Marlin engine that powers the second stage of the booster.
Meanwhile, Stage 1 flips, starting and decelerating three engines, plunging into the lower atmosphere, braking with one engine, and landing on a SpaceX drone hundreds of miles below. did.
The on-target touchdown was SpaceX’s 65th successful offshore booster recovery and 87th overall.
In the second stage, two engine ignitions were performed to reach the planned elliptical orbit, and the SXM-8 satellite flew on its own 32 minutes after takeoff. The satellite will use its own propulsion system over the next few weeks to reach the required circular orbit of 22,300 miles above the equator.
The 15,400-pound SXM-8 spacecraft features a large dish-shaped mesh antenna designed to relay programming to mobile radio throughout North America. The design life of the satellite is 15 years.
SiriusXM initially decided to replace the two older satellites XM-3 and XM-4 (nicknamed Rhythm and Blues, respectively) with the SXM-7 launched last December and the same SXM-8 launched on Sunday. I was planning.
Due to the failure of the SXM-7 earlier this year, it is not yet known which older satellite it will replace after the SXM-8 is fully operational.
Whatever the outcome, company officials said the loss of the $ 225 million insured SXM-7 did not affect the implementation of the program and both old satellites remained healthy. Stated. Another older generation satellite, the XM-5, can be used as an orbital spare if needed.
