Welcome to Edition 3.24 of the Rocket Report! It’s December, and we could see a number of big smallsat launches this month, including from Virgin Orbit and Astra. But in the immediate future, our eyes are on South Texas, where a Starship prototype is due to make a high leap early next week.

Aevum unveils its Ravn X launch system. Until now, Aevum has largely operated in the background. But now, it’s ready to show off some hardware, and it’s starting with the “Ravn X” launch system’s first stage, Ars reports. This autonomous aircraft and launch vehicle measures 24 meters long and has a wingspan of 18 meters. It has a gross takeoff mass of 25,000kg—massive for an uncrewed aerial vehicle. It will drop a rocket capable of carrying 100kg to Sun-synchronous orbit.

Seeking to make satellite delivery a commodity … The company is targeting next year for its first launch. Even as it has finalized the Ravn X first stage, Aevum has been developing a rocket with two liquid-fueled engines for its main stage, each with 5,000 pounds of thrust, and a single upper-stage engine. These engines have been hot-fire tested beyond their full duration burns and have gone through qualification and acceptance testing, the company said. Aevum claims it has secured launch contracts worth more than $1 billion over the next decade, including the Air Force’s ASLON-45 mission.

Virgin Orbit sets date for second launch attempt. On Monday, Virgin Orbit announced it would try a second orbital flight of its LauncherOne rocket on Saturday, December 19. The four-hour window will open at 10am PT (18:00 UTC). During the company’s first demo flight last May, the rocket was successfully dropped from its carrier aircraft, and its engine ignited for a few seconds before running out of LOX due to a blocked line.

This time, there will be a customer … That mission carried no payloads, but this one will. Through its Venture Class Launch Services program, NASA is providing nine CubeSat missions comprising 10 total spacecraft to fly on the Launch Demo 2 mission. The company said it still has to conduct a wet dress rehearsal before embarking upon its launch attempt. Good luck! (submitted by Ken the Bin)

Danish Nuclear Startup Taps Billionaire for Asian Reactor

(Bloomberg) — A Danish company planning to manufacture small modular reactors raised about 20 million euros ($24 million) to bring a floating nuclear-power station to southeast Asia.

Seaborg Technology AS raised the funds to bring nuclear power at sea to parts of southeast Asia which rely on fossil fuels and where renewables aren’t yet an option. Floating reactors are as old as the nuclear age, with units powering submarines and icebreakers for some seven decades. Last year, Russia deployed new reactors on barges to light up remote Arctic coastlines.

Seaborg envisions building its molten fluoride salt reactors in South Korean shipyards after developing the technology in Denmark in a bid to keep costs down. Completed barges will then be towed to where they’re needed. The plan is to connect the first unit to a grid by 2025.

“We will provide a significantly cheaper alternative to coal in regions with no access to renewable energy,” said Troels Schonfeldt, chief executive officer of Seaborg.

Barges will be tugged to their final location where it can be anchored for as long as 24 years. Each barge can be outfitted with 200 to 600 megawatts of power capacity, depending on how many reactors are on board.

The money, raised from mostly private investors including fashion billionaire Anders Holch Povlsen, will be used to hire about 50 people and build a state of the art laboratory, Schonfeldt said.
