Welcome to Edition 8.02 of the Rocket Report! It's worth taking a moment to recognize an important anniversary in the history of human spaceflight next week. Fifty years ago, on July 15, 1975, NASA launched a three-man crew on an Apollo spacecraft from Florida and two Russian cosmonauts took off from Kazakhstan, on course to link up in low-Earth orbit two days later. This was the first joint US-Russian human spaceflight mission, laying the foundation for a strained but enduring partnership on the International Space Station. Operations on the ISS are due to wind down in 2030, and the two nations have no serious prospects to continue any partnership in space after decommissioning the station.

Sizing up Europe's launch challengers. The European Space Agency has selected five launch startups to become eligible for up to 169 million euros ($198 million) in funding to develop alternatives to Arianespace, the continent's incumbent launch service provider, Ars reports. The five small launch companies ESA selected are Isar Aerospace, MaiaSpace, Rocket Factory Augsburg, PLD Space, and Orbex. Only one of these companies, Isar Aerospace, has attempted to launch a rocket into orbit. Isar's Spectrum rocket failed moments after liftoff from Norway on a test flight in March. None of these companies is guaranteed an ESA contract or funding. Over the next several months, ESA and the five launch companies will negotiate with European governments for funding leading up to ESA's ministerial council meeting in November, when ESA member states will set the agency's budget for at least the next two years. Only then will ESA be ready to sign binding agreements.

Welcome to Edition 7.48 of the Rocket Report! The shock of last week's public spat between President Donald Trump and SpaceX founder Elon Musk has worn off, and Musk expressed regret for some of his comments going after Trump on social media. Musk also backtracked from his threat to begin decommissioning the Dragon spacecraft, currently the only way for the US government to send people to the International Space Station. Nevertheless, there are many people who think Musk's attachment to Trump could end up putting the US space program at risk, and I'm not convinced that danger has passed.

Quebec invests in small launch company. The government of Quebec will invest CA$10 million ($7.3 million) into a Montreal-area company that is developing a system to launch small satellites into space, The Canadian Press reports. Quebec Premier François Legault announced the investment into Reaction Dynamics at the company's facility in Longueuil, a Montreal suburb. The province's economy minister, Christine Fréchette, said the investment will allow the company to begin launching microsatellites into orbit from Canada as early as 2027.

Welcome to Edition 7.41 of the Rocket Report! NASA and its contractors at Kennedy Space Center in Florida continue building a new mobile launch tower for the Space Launch System Block 1B rocket, a taller, upgraded version of the SLS rocket being used for the agency's initial Artemis lunar missions. Workers stacked another segment of the tower a couple of weeks ago, and the structure is inching closer to its full height of 355 feet (108 meters). But this is just the start. Once the tower is fully assembled, it must be outfitted with miles of cabling, tubing, and piping and then be tested before it can support an SLS launch campaign. Last year, NASA's inspector general projected the tower won't be ready for a launch until the spring of 2029, and its costs could reach $2.7 billion. The good news, if you can call it that, is that there probably won't be an SLS Block 1B rocket that needs to use it in 2029, whether it's due to delays or cancellation.

Fresh details on Astra's strategic pivot. Astra, the once high-flying rocket startup that crashed back to Earth with investors before going private last year, has unveiled new details about its $44 million contract with the Department of Defense, Space News reports. The DOD contract announced last year supports the development of Rocket 4, a two-stage, mobile launch vehicle with ambitions to deliver cargo across the globe in under an hour. While Astra's ill-fated Rocket 3 focused on launching small satellites into low-Earth orbit, Astra wants to make Rocket 4 a military utility vehicle. Rocket 4 will still be able to loft conventional satellites, but Astra's most lucrative contract for the new launch vehicle involves using the rocket for precise point-to-point delivery of up to 1,300 pounds (590 kilograms) of supplies from orbit via specialized reentry vehicles. The military has shown interest in developing a rocket-based rapid global cargo delivery system for several years, and it has a contract with SpaceX to study how the much larger Starship rocket could do a similar job.

In an era of reusable rockets and near-daily access to space, NASA is still paying more than it did 30 years ago to launch missions into orbit, according to a study soon to be published in the scientific journal Acta Astronautica.

Launch is becoming more routine. Every few days, SpaceX is sending another batch of Starlink Internet satellites to orbit, and other kinds of missions fill up the rest of SpaceX's launch schedule. SpaceX, alone, has ample capacity to launch the handful of science missions NASA puts into space each year. If supply outpaces demand, shouldn't prices go down?

It's not so simple. NASA is one of many customers jockeying for a slot on SpaceX's launch manifest. The US military is launching more missions than ever before, and SpaceX is about to become the Pentagon's top launch provider. SpaceX already launches more missions for NASA than any other rocket company.

Welcome to Edition 7.39 of the Rocket Report! Not getting your launch fix? Buckle up. We're on the cusp of a boom in rocket launches as three new megaconstellations have either just begun or will soon begin deploying thousands of satellites to enable broadband connectivity from space. If the megaconstellations come to fruition, this will require more than a thousand launches in the next few years, on top of SpaceX's blistering Starlink launch cadence. We discuss the topic of megaconstellations in this week's Rocket Report.

So, what is SpinLaunch doing now? Ars Technica has mentioned SpinLaunch, the company that literally wants to yeet satellites into space, in previous Rocket Report newsletters. This company enjoyed some success in raising money for its so-crazy-it-just-might-work idea of catapulting rockets and satellites into the sky, a concept SpinLaunch calls "kinetic launch." But SpinLaunch is now making a hard pivot to small satellites, a move that, on its face, seems puzzling after going all-in on kinetic launch and even performing several impressive hardware tests, throwing a projectile to altitudes of up to 30,000 feet. Ars got the scoop, with the company's CEO detailing why and how it plans to build a low-Earth orbit telecommunications constellation with 280 satellites.

In the last week, the US Space Force awarded SpaceX a $5.9 billion deal to make Elon Musk's space company the Pentagon's leading launch provider, and then it assigned the vast majority of this year's most lucrative launch contracts to SpaceX.

On top of these actions, the Space Force reassigned the launch of a GPS navigation satellite from United Launch Alliance's long-delayed Vulcan rocket to fly on SpaceX's Falcon 9. ULA, a joint venture between Boeing and Lockheed Martin, is SpaceX's chief US rival in the market for military satellite launches.

Given the close relationship between Musk and President Donald Trump, it's not out of bounds to ask why SpaceX is racking up so many wins. Some plans floated by the Trump administration involving SpaceX in recent months have raised concerns over conflicts of interest.

For the second time in six months, SpaceX will deploy a US military satellite that was sitting in storage, waiting for a slot on United Launch Alliance's launch schedule.

Space Systems Command, which oversees the military's launch program, announced Monday that it is reassigning the launch of a Global Positioning System satellite from ULA's Vulcan rocket to SpaceX's Falcon 9. This satellite, designated GPS III SV-08 (Space Vehicle-08), will join the Space Force's fleet of navigation satellites beaming positioning and timing signals for military and civilian users around the world.

The Space Force booked the Vulcan rocket to launch this spacecraft in 2023, when ULA hoped to begin flying military satellites on its new rocket by mid-2024. The Vulcan rocket is now scheduled to launch its first national security mission around the middle of this year, following the Space Force's certification of ULA's new launcher last month.

The US Space Force announced Friday it selected SpaceX, United Launch Alliance, and Blue Origin for $13.7 billion in contracts to deliver the Pentagon's most critical military to orbit into the early 2030s.

These missions will launch the government's heaviest national security satellites, like the National Reconnaissance Office's large bus-sized spy platforms, and deploy them into bespoke orbits. These types of launches often demand heavy-lift rockets with long-duration upper stages that can cruise through space for six or more hours.

The contracts awarded Friday are part of the next phase of the military's space launch program once dominated by United Launch Alliance, the 50-50 joint venture between legacy defense contractors Boeing and Lockheed Martin.
