SpaceX is preparing a Falcon 9 launch from Cape Canaveral carrying SiriusXM's SXM-11 broadcasting satellite, which will replace two aging spacecraft in geostationary orbit. Spaceflight Now reports the satellite was built by Intuitive Machines and is set to fly during a nearly four-hour evening launch window, with weather odds improving as the window progresses. The mission highlights how established satellite operators are still investing in large replacement spacecraft even as launch cadence and commercial bus partnerships keep accelerating.

LAUNCH
SpaceX launched 24 more Starlink satellites from Vandenberg on Sunday morning, adding to a constellation that Spaceflight Now says now exceeds 10,700 spacecraft in orbit. The mission used Falcon 9 booster B1088 on its 17th flight and ended with another droneship recovery in the Pacific. The launch shows how routinely SpaceX is now refreshing and expanding its broadband network while reusing boosters at very high cadence.

SCIENCE
ESA released a new Euclid mosaic of the Milky Way's galactic bulge that captures more than 60 million stars in what NASASpaceFlight describes as the largest and most detailed view of the region yet. The observation was made outside Euclid's normal cosmology survey to support NASA's upcoming Roman Space Telescope exoplanet campaign. The collaboration shows how current space observatories are already being used to improve the science return of missions that have not launched yet.

Policy & Politics

ELECTIONS
Roll Call reports that Rep. Julia Letlow won Louisiana's Republican Senate runoff, defeating former Rep. John Fleming and moving into the general election as the favorite. The result again underscored the strength of President Trump's endorsement in Republican primaries and formally knocked Sen. Bill Cassidy's anti-Trump lane out of contention after the earlier round. It gives Republicans a clearer Senate map in a race that had become a proxy fight over Trump's continued hold on the party.

HOUSING
House Speaker Mike Johnson said he will send a bipartisan housing bill to President Trump on Monday even though Trump has threatened to withhold his signature unless the Senate first acts on separate elections legislation. The Hill says the standoff pits a broadly supported measure against a White House demand for leverage on another policy fight. The episode is a reminder that even bipartisan bills can still become bargaining chips in the administration's wider congressional agenda.

SATCOM
SiriusXM's SXM-11 mission pairs a major commercial satellite operator with launch provider SpaceX and manufacturer Intuitive Machines for a long-planned fleet refresh in geostationary orbit. The new spacecraft is intended to replace two aging broadcasting satellites, extending SiriusXM's capacity for satellite radio service. It is a clear example of incumbent space businesses still spending on large replacement assets while relying on a more flexible commercial launch market to get them on orbit.

Geopolitics & Defense

FUNDING
Rep. Mark Harris said Congress will likely need to use budget reconciliation to provide additional Pentagon funding for the Iran war, arguing that the Senate's filibuster rules could otherwise block the measure. According to The Hill, the comment points to an emerging view among Republicans that any sustained military campaign will quickly require a separate funding vehicle. It also signals that the politics of war financing may become entangled with the party's broader budget strategy.

PENTAGON
Sen. Tim Kaine said the ouster of Gen. Chris Donahue appears tied to Defense Secretary Pete Hegseth's personal grudge against the Army and warned that the Pentagon may be pushing out dissenting voices. The Hill reports that Kaine framed the move as part of a broader pattern of coming down hardest on the service branch. The clash adds another political layer to questions about senior military leadership, civilian control and internal decision-making at the Defense Department.
