SpaceX launched SiriusXM's SXM-11 satellite late Sunday on a Falcon 9 from Cape Canaveral, sending a 7.5-ton broadcast spacecraft toward geostationary orbit to replace two satellites that went up in 2009 and 2010.
Liftoff from Space Launch Complex 40 came at 10:25 p.m. EDT (0225 UTC), at the open of a four-hour window the 45th Weather Squadron had given an 80 percent chance of cooperating. It did. The interesting part of the mission was not that it worked, but how unremarkable working has become.
B1085 flies its 17th mission and lands for the 158th time
The booster was tail number B1085, on its 17th flight. Its résumé reads like a cross-section of the company's manifest: NASA's Crew-9, a U.S. Space Force RRT-1 mission, Firefly's Blue Ghost Mission 1, the Fram2 polar flight, SiriusXM's own SXM-10, Europe's MTG-S1 weather satellite, EchoStar XXV, and nine Starlink batches.
About 8.5 minutes after liftoff it touched down on the drone ship A Shortfall of Gravitas in the Atlantic, the platform's 158th successful recovery. That ties the count held by the retired Just Read the Instructions, now reassigned to Starship work.
A geostationary comsat replacement is among the least remarkable things SpaceX does in 2026, which is the entire achievement.
SXM-11 replaces satellites from 2009 and 2010
The payload separated from the upper stage a little over half an hour after launch. SXM-11 and its still-grounded twin, SXM-12, were built to retire XM-5 and Sirius FM-5, which reached orbit in 2010 and 2009. SiriusXM calls the new spacecraft the most powerful in its fleet, with stronger signal reception, expanded coverage into Alaska, and continued service across the United States, Canada, and the Caribbean.
Fuel is most of the satellite, and most of the point
SiriusXM says roughly 60 percent of the 7.5-ton spacecraft's mass is propellant. That ratio is the business. A geostationary satellite earns its keep by holding one fixed slot over the equator, and holding that slot means burning fuel for station-keeping, year after year. When the tank runs low the bird drifts, the coverage degrades, and the operator is pushed into the move it has been planning for a decade.
XM-5 and Sirius FM-5 are 15 and 16 years into that clock. The refresh was never a question of whether. Only of when the gauge read empty.

Lanteris builds the bus Intuitive Machines just bought for $800 million
SXM-11 sits on the IM-1300 satellite bus, built by Lanteris Space Systems, with solar arrays that span 106 feet (32.3 m) once deployed. Lanteris is the manufacturing business formerly branded Maxar Space Systems, which Texas-based Intuitive Machines acquired in January 2026 for about $800 million.
That deal is the quiet structural story under the launch. A company best known for landing on the Moon now owns a factory that builds large geostationary communications satellites.
For SiriusXM, the calculation is coverage continuity. The company's whole moat is an uninterrupted signal, and a subscriber does not care which satellite carries it. SXM-10, launched in June 2025, is rated in service until 2040 in a filing to the SEC, which tells you the cadence the operator plans around: roughly fifteen years per slot, with the replacement bird flying well before the old one quits. For Intuitive Machines, the read is harder. Having paid $800 million for the bus line, it now needs the IM-1300 order book to look like an asset rather than a liability it inherited.
SXM-12 is the obvious next flight, the twin built to retire the second aging satellite, and it should go up within roughly a year. The longer question belongs to Intuitive Machines. The SiriusXM pair alone does not justify $800 million, so the thing to watch is whether IM-1300 orders arrive from anyone else. If they do not, the acquisition starts to look less like a bet on geostationary manufacturing and more like a way to buy a backlog that was already on the books.
