Ależ te starty spowszedniały. Największą atrakcją jest SCRUB. Startują, lądują, dostarczają ładunek na orbitę... nuuuda. I oby jak najdłużej :)

ps.
Na szczęście Starship dostarcza atrakcji.

Jak w normalnym ruchu ulicznym. Wystartowanie. Prawidłowe oddzielenie. Wylądowanie. Normalka.

Wizualnie wydaje się, że separacja nastąpiła z małym opóźnieniem.

SXM 7 separation confirmed. Now flying over Africa, SiriusXM's newest satellite has deployed from the Falcon 9 rocket to begin a mission of more than 15 years beaming radio programming across the United States, Canada, and the Caribbean.

SpaceX launches SiriusXM satellite
by Jeff Foust — December 13, 2020

WASHINGTON — A SpaceX Falcon 9 launched a new spacecraft for satellite radio company SiriusXM Dec. 13 as the company nears the end of a record-setting year.

The Falcon 9 lifted off from Space Launch Complex 40 at Cape Canaveral Space Force Station at 12:30 p.m. Eastern. SpaceX scrubbed a previous launch attempt two days earlier at just 30 seconds before liftoff because of a potential, but unspecified, issue with ground systems.

The rocket’s upper stage deployed the SXM-7 satellite into a geostationary transfer orbit 31 minutes after liftoff. The rocket’s first stage successfully landed on a droneship in the Atlantic Ocean. That stage made its seventh flight, having previously launched the Demo-1 commercial crew test flight, the Radarsat Constellation Mission and four sets of Starlink satellites.

SXM-7 is one of two new digital audio radio service satellites that SiriusXM ordered from Space Systems Loral (now Maxar Technologies) in 2016. The satellite, weighing nearly 7,000 kilograms at launch, will generate more than 20 kilowatts of power and deploy a large antenna that will broadcast programming for SiriusXM subscribers in North America and the Caribbean.

The satellite is intended to replace XM-3, a satellite launched in 2005 and operating at 85 degrees west in geostationary orbit. A second satellite, SXM-8, will launch in 2021 to replace XM-4 at 115 degrees west.

The launch is the 24th orbital mission in 2020 for SpaceX, the most launches the company has performed in a single year. The SXM-7 launch, though, was only the third where the primary customer was neither the U.S. government nor SpaceX itself. Fourteen Falcon 9 launches have been of SpaceX’s Starlink satellites. Five have been for NASA, including commercial crew and cargo missions to the International Space Station and the Sentinel-6 Michael Freilich ocean science satellites, while two have carried GPS satellites for the U.S. Space Force. SpaceX also performed a suborbital Falcon 9 launch in January as an in-flight abort test of the Crew Dragon spacecraft for NASA.

Besides SXM-7, the only Falcon 9 launches for customers other than the U.S. government and SpaceX have been the July launch of the ANASIS-2 military communications satellite for South Korea and the August launch of the SAOCOM 1B radar imaging satellite for CONAE, Argentina’s space agency.

One more Falcon 9 launch is scheduled for this year, carrying a classified payload for the National Reconnaissance Office on a mission designated NROL-108. That launch is scheduled for no earlier than Dec. 17.

SpaceX Launches 25th Mission of the Year with Sirius XM-7, Using Only 11 Rockets
By Ben Evans, on December 13th, 2020

(...) Today’s late-morning launch comes after a remarkable year for SpaceX, which has seen a pair of piloted Crew Dragons and a pair of unpiloted Cargo Dragons voyage to the International Space Station (ISS), two Block III Global Positioning System (GPS) navigation and timing satellites, 14 Starlink missions—a total of 833 of these low-orbiting internet communications birds—as well as South Korea’s ANASIS-II military communications sentinel, Argentina’s SAOCOM-1B radar-imaging platform and last month’s launch of the Sentinel-6A Michael Freilich mission.

Including this morning’s liftoff, the 25 flights have been conducted using only 11 Falcon 9 cores. Two of those cores have logged three launches, a further two have done four and today’s outing by B1051 makes it the first booster to record a fifth mission in a single calendar year. (...)

Primary payload for today’s launch is the 15,000-pound (7,000 kg) SXM-7 high-powered broadcasting satellite, bound for Geostationary Orbit and an expected 15-year operational lifetime. Provided by New York-headquartered SiriusXM Holdings, Inc., the satellite will support Digital Audio Radio Service (DARS) capability.

Contracts to build SXM-7 (and its twin, SXM-8, targeted to fly atop another Falcon 9 next year) were signed with Space Systems/Loral (SS/L)—now a subsidiary of Maxar Technologies—back in July 2016. Both are based upon the tried-and-true SSL-1300 “bus” and can generate more than 20 kilowatts of electrical power and feature large unfurlable S-band antenna reflectors to broadcast to radios without the need for large ground-based dishes.

When it enters active service, SXM-7 will replace an earlier satellite, XM-3, which is now nearing the end of its lifetime, having been placed into orbit way back in March 2005. (...)

SiriusXM satellite rides SpaceX rocket into orbit
December 13, 2020 Stephen Clark

(...) A hefty new satellite to beam SiriusXM radio programming across North America rode a SpaceX Falcon 9 rocket into orbit Sunday from Cape Canaveral on course to replace an aging broadcast station launched more than 15 years ago.

SiriusXM’s SXM 7 spacecraft, built by Maxar in Palo Alto, California, is the first of two new-generation digital broadcasting satellites set to join the company’s fleet in the coming months. (...)

The maneuvers will boost SXM 7 toward an operational perch in geostationary orbit more than 22,000 miles (nearly 36,000 kilometers). In that orbit, the spacecraft will orbit Earth at the same rate the planet rotates, giving SXM 7 a fixed view of the Americas 24 hours a day, seven days per week.

“The satellite will provide continuous, reliable delivery of SiriusXM’s audio entertainment and information services to consumers in the United States, and will expand SiriusXM’s coverage area in Canada and the Caribbean, for years to come,” SiriusXM saiid in a statement. “SXM 7 will deliver the highest power density of any commercial satellite on orbit, sending more than 8,000 watts of content to the continental U.S., Canada, Puerto Rico, and the Caribbean, increasing the power and reach of the signal for SiriusXM.”

Once in geostationary orbit, the SXM 7 satellite — based on Maxar’s 1300-series spacecraft design — will unfurl a large S-band antenna made reflector made by L3Harris to broadcast radio signals to receivers on moving vehicles.

SXM 7 is expected to replace the XM 3 radio broadcasting satellite at 85 degrees west longitude. The Boeing-built XM 3 satellite launched in 2005 aboard a Sea Launch Zenit 3SL rocket.

The launch of SXM 7 was scheduled earlier this year, but a problem encountered during spacecraft testing at Maxar delayed the mission. SpaceX scrubbed a launch attempt Friday to conduct additional ground system checkouts.

SiriusXM said Sunday it has five satellites in its active fleet, with XM 3 the oldest still operational.

The launch of SXM 7 and a twin satellite named SXM 8 next year — also on a SpaceX Falcon 9 rocket — will extend SiriusXM’s services through at least 2036, the company said in a statement. (...)

17 grudnia stopień 1051.7 wrócił do portu Canaveral.
Niewiele brakowało do przewrócenia stopnia.
