A four-person crew of astronauts and a cosmonaut arrived at the International Space Station on Thursday, completing a 29-hour trek in a SpaceX capsule that began in Florida.

Sending rockets into space requires sacrificing expensive equipment, burning massive amounts of fuel, and risking potential catastrophe. So in the space race of the 21st century, some engineers are abandoning rockets for something more exciting: elevators. What would it take to build such a structure? Fabio Pacucci explores the physics behind modern space elevators. [Directed by Tjoff Koong Studios, narrated by Addison Anderson].

The super heavy-lift Long March 9 rocket could send humans to the Moon and Mars.

China successfully tested a new engine for its Long March 9 rocket, which it aims to eventually use to send the first crewed Chinese mission to the Moon.

The China National Space Administration (CNSA) said it has overcome technical difficulties in building its first prototype Yf-79 engine for the rocket.

Although today’s rocket engines are advanced and powerful, they tend to rely on traditional — and naturally volatile — fuels. Firehawk Aerospace has a safer and more stable new solid fuel, new engines, and millions in new funding to take it through the next round of tests to its first in-atmosphere demonstration launch.

Firehawk appeared on the scene two years ago with a fresh take on hybrid engines; the breakthrough made by CEO Will Edwards and chief scientist Ron Jones was to give that fuel a structure and 3D print it in a specially engineered matrix.

The structured, solid fuel grain is more stable and easier to transport than other fuels, and burns in a very predictable way. The company designed engines around this concept and tested them at smaller scales, though they have also been working on the kind of engine you might actually use if you were going to space. But the company has said that one of the strengths of the system is its adaptability.

New scientific research suggests Mars astronauts would get a horrifying does of radiation.

How serious is it?
