Starship is stacked for its first try at orbit

SpaceX finished stacking the Starship for Flight 14 early on September 23, setting Ship 41 on top of Booster 21 at Starbase's Pad 2 ahead of a wet dress rehearsal. Launch is set for a 75-minute window opening at 8:15 a.m. EDT on September 28. It will be Starship's first attempt to reach orbit after 10 years of development. Ship 41 carries 26 Starlink V3 satellites, which would be the first of the larger V3s to stay in orbit. Earlier Starship flights carried small batches of V3s on suborbital paths, so those satellites burned up on reentry.

    SpaceX gets exclusive access to the military's best space tracking data

    The Defense Department has agreed to give SpaceX exclusive access to the most detailed version of US Space Command's High Accuracy Catalog of objects in orbit, according to a dozen government and industry sources. A Space Force official said the Joint Commercial Operations Cell signed an agreement trading the catalog for data from SpaceX's Stargaze star-tracking cameras, for SpaceX's internal use only. Commercial space tracking firms worry the data could sharpen the services SpaceX sells to other operators and undercut their market. Neither the Space Force nor SpaceX answered questions about the terms.

    Iridium shareholders approve the sale to Rocket Lab

    Iridium stockholders voted on September 24 to approve Rocket Lab's planned acquisition of the satellite operator, with about 99.6% of votes cast in favor. The shares voting yes made up about 81% of those outstanding. The deal still needs regulatory approvals before it can close. Rocket Lab plans to lean on Iridium's L-band network for government and navigation services more than for consumer communications.

    Space Force hires an Impulse Mira to watch the geostationary belt

    Impulse Space won a $28 million Space Force contract on September 22 for a space domain awareness demonstration. A government-furnished optical sensor will fly on Impulse's Mira vehicle in low Earth orbit and point up at the geostationary belt to track and characterize spacecraft there. The mission will launch on a government-provided rocket. Part of the funding comes from a $19.75 million award under the Pentagon's APFIT program, sponsored by US Space Command.

    A turbopump problem will thin out Ariane 6 launches this year

    ESA confirmed it is aware of delays to the Ariane 6 schedule after reports of a turbopump anomaly found in ground testing in August. ArianeGroup and Arianespace said this year's missions will be rescheduled while extra checks run on the production line, though they still expect 9 to 10 launches a year from 2027. Earlier reporting suggested only one or two more Ariane 6 flights in 2026, down from three or four.

    Europe's first commercial Moon rover books a ride on Blue Moon

    Belgium's Space Applications Services will send its LUVMI-M rover to the lunar south pole on a Blue Origin Blue Moon Mark 1 lander, now expected in early 2029. The 20-kilogram rover can carry 20 kilograms of customer payloads and travel up to five kilometers over a 10 to 14 day mission. The company says the mission is fully commercial, paid for by payload and operations contracts.

    ISRO breaks ground on a space tracking radar center in Assam

    Assam's chief minister laid the foundation stone on September 21 for ISRO's Advanced Radar Research Centre at Chandrapur, near Guwahati. The center, built by ISRO's tracking network ISTRAC, is part of Project NETRA and will track objects and debris in orbit to protect India's satellites. It is the first major space surveillance site in India's Northeast, on about 70 acres provided by the state.
