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.

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

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.

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.

David versus Goliath stories captivate us, especially when David brings a slingshot that looks like alien technology. Enter Stavatti Aerospace, a 25-person firm from Niagara Falls taking on Boeing and Northrop Grumman for one of the most lucrative defense contracts in naval aviation. Their weapon of choice? The SM-39 Razor, a fighter design so visually striking it demands a double-take. The triple-fuselage "Batwing" configuration breaks from a century of conventional aircraft architecture, presenting a form that's more science fiction than traditional aerospace engineering.

Blue Origin, the rocket company owned by Amazon founder Jeff Bezos, says it will launch more than 5,400 satellites to create a new communications network. Named TeraWave, it will offer continuous internet access around the world, with the ability to move large amounts of data much more quickly than rival services. But even after launching thousands of satellites, Blue Origin would still have far fewer in orbit than Elon Musk's Starlink, which currently dominates the satellite internet market.
