NASA has 30 days to kick off a program for a mid-power space reactor ready for launch by 2030. A lunar variant is required, as is an option for nuclear electric propulsion.

In a high-growth scenario for the space industry, there could be as many as 2,000 launches per year, which her modeling shows could result in about 3 percent ozone loss, equal to the atmospheric impacts of a bad wildfire season in Australia. She said most of the damage comes from chlorine-rich solid rocket fuels and black carbon in the plumes. The black carbon could also warm parts of the stratosphere by about half-a-degree Celsius as it absorbs sunlight.

JAXA's analysis indicated that the manufacturing process for a component holding the satellite payload was flawed, primarily due to unexpected high temperatures that weakened the adhesive used.

Redwire focuses on space infrastructure and autonomous systems. The company completed its Edge Autonomy acquisition and reported 50.7% year-over-year revenue growth. Management maintained full-year guidance of $320 to $340 million, and the book-to-bill ratio of 1.25 suggests demand is holding. But the business is bleeding cash with a net loss of $41.2 million in Q3, nearly double the $21 million loss from the prior year. Gross margin sits at just 16.3%, leaving almost no room for error.

Could IT infrastructure, and even the rise of AI, eventually migrate beyond the atmosphere? Amazon founder Jeff Bezos predicted in October that gigawatt-scale, solar-powered data centers would be a reality within 10 to 20 years. At the World Economic Forum in Davos this week, Elon Musk was even more ambitious: AI data centers in the "final frontier" could be viable within two to three years. Google also plans to deploy its TPU chips in orbit via Project Suncatcher.

Methane is better suited for reusable engines because they leave less behind sooty residue than kerosene, which SpaceX uses on the Falcon 9 rocket.

Robert Goddard, a Massachusetts-born physicist, launched the world's first liquid-fueled rocket on this date 100 years ago. It was not an overly impressive flight. The rocket, fueled by gasoline and liquid oxygen, rose just 41 feet into the air, and the flight lasted 2.5 seconds before it struck ice and snow. Nevertheless, this rocket, named "Nell," represented a historic achievement that would help launch the modern age of spaceflight.

The company is planning to launch a 1,100-pound satellite on a Falcon 9 rocket in October as part of an audacious proof of concept. The goal is to test water as the fuel for both electrical and chemical propulsion, processes that involve shooting out a stream of plasma with the use of a magnetic field and burning fuel at high temperature and pressure to generate thrust, respectively.

"You absolutely have to have a plan to compete with SpaceX on price." Welcome to Edition 8.29 of the Rocket Report! We have a stuffed report this week with news from across the launch spectrum. Long-term, probably the most significant development this week was a subscale version of the Long March 10 rocket successfully launching and then executing a picture-perfect ocean landing. China is catching up rapidly to the United States when it comes to reusable launch.

Entrants will be required to write three- to five-page white papers that explain their idea and how they would shape markets and strengthen the space economy or national security. Papers are due by June 30, and judging will be complete by August 15. As an additional incentive, the best ideas will be briefed to relevant policymakers, including key members of Congress, NASA Administrator Jared Isaacman, and Saltzman, of the Space Force.

United Launch Alliance's Vulcan Centaur reached orbit on February 12 despite "a significant performance anomaly" that saw one of its four solid rocket boosters burn through its nozzle during ascent. Viewers of the launch from Cape Canaveral at 0422 EST (0922 UTC) were treated to some impressive fireworks as the part detached in a shower of fragments. It was the fourth launch of ULA's replacement for the Atlas V and Delta IV rocket, and the second in which an anomaly was noted with the booster.
