The briefing

Rocket Lab agreed to acquire Iridium Communications for $54 per share in cash and stock, valuing the satellite operator at $8 billion in what Peter Beck called "the logical next step" for his company. The merger agreement, signed June 28 and expected to close in mid-2027, pairs Rocket Lab's Electron and coming Neutron launchers and satellite manufacturing base with Iridium's 66-satellite L-band constellation, roughly 2.55 million customers, and a nascent PNT service.

Beck told investors he chose acquisition over building because "you can spend many years building your satellites and launching your satellites, and it's like a decade before you get firm recurring revenue." Iridium CEO Matt Desch said the company had not solicited a sale and engaged bankers only after unsolicited industry interest, and the Iridium board unanimously recommended the deal.

NASA awarded L3Harris one of seven three-year, fixed-price contracts to develop picometer-level thermal and optical stability technology for the Habitable Worlds Observatory, work that will run out of Rochester, New York and build on L3Harris's thermal-control heritage from the Nancy Grace Roman Space Telescope. Gilat separately disclosed $43 million of additional Sidewinder electronically steered antenna orders from a major in-flight connectivity provider, with line-fit and retrofit deliveries planned over the next 18 months.

NASA picks L3Harris for Habitable Worlds Observatory stability work

LHX

NASA awarded L3Harris one of seven three-year, fixed-price contracts to develop critical technology for the Habitable Worlds Observatory, a flagship deep-space telescope designed to search distant planets for signs of life. L3Harris will work in Rochester, New York on thermal and optical stability technology intended to hold the telescope steady at the picometer scale, building on its thermal-control system for the Nancy Grace Roman Space Telescope. Company executive Charles Clarkson called achieving that stability "one of the most demanding engineering challenges ever attempted."

SpaceX flies SXM-11 for SiriusXM on Falcon 9

SpaceX

SpaceX launched SiriusXM's SXM-11 satellite from Cape Canaveral Space Force Station at 10:25 p.m. ET on June 28, with the roughly 34-minute mission delivering the highest-power satellite in the SiriusXM fleet to geostationary transfer orbit. SXM-11 is built on the 1300-class platform under a two-satellite deal SiriusXM signed with Maxar Technologies in 2022 that also covers SXM-12; Maxar's space business is now part of Intuitive Machines. The satellite is intended to enhance signal reception, expand coverage in Alaska, and support audio services across the United States, Canada, and the Caribbean.

Aerospace Corp. study questions economics of super-heavy lift rockets

SpaceX

A June 29 report from The Aerospace Corporation argues that beyond a certain size, super-heavy lift vehicles can see per-kilogram launch costs climb as ground operations and turn-time complexity outweigh the benefits of larger payload capacity. Aerospace classifies super-heavy lift as vehicles that can place at least 50 metric tons into low Earth orbit, a bucket that today includes Falcon Heavy and SLS and adds Starship, the upgraded New Glenn 9x4, and China's Long March 9 and 10 in development.
