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.

FireDrone is an aerogel-covered that can help firefighters in rescue missions by surveying for victims inside burning buildings. The assistive device aims to be the 'flying eye' in extreme environments so humans can be sure of who are and what is inside a site before going in. The FireDrone flying machine resembles a small quadcopter with its four arms and spinning propellers, but unlike regular drones, the parts of the device are built to survive high temperatures.

Artemis III aims to land astronauts near the lunar South Pole, relying on SpaceX's Starship-derived Human Landing System (HLS) - a vehicle that has yet to achieve orbit, let alone venture anywhere near the Moon. It's an extraordinarily ambitious undertaking, and one the ASAP report has formally classified as high risk.

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.

Heat shields are crucial: when spacecraft reenter Earth's atmosphere, they heat up, burning through the sky like a shooting star. Without a protective layer, any living thing inside a returning spacecraft would be exposed to temperatures about half as hot as the surface of the sun, or 5,000 degrees Fahrenheit (2,760 degrees Celsius). In Orion's case, the heat shield is made of Avcoatthe same material that protected the Apollo capsules, with a key structural difference.

An ailing astronaut returned to Earth with three others on Thursday, ending their space station mission more than a month early in NASA's first medical evacuation. SpaceX guided the capsule to a middle-of-the-night splashdown in the Pacific near San Diego, less than 11 hours after the astronauts exited the International Space Station. Their first stop was a hospital for an overnight stay.
