A lesson in fluid dynamics.

Could astronauts surf to Mars assisted by a hypersonic shockwave? A new paper in the Journal of Fluid Dynamics suggests it’s a more likely scenario than we think, combining traditional propulsion with a shockwave method for mixing fuel ratios to reach their full explosive potential.

In the new paper, researchers from the University of Southern California investigate the way applying a shockwave helps or hinders how the “scalars,” or different fluids, can mix effectively. Take a leisurely swirl of oxygen and fuel and you might only reach regular supersonic speeds. But add the Nutribullet impact of a shockwave and the oxygen-fuel smoothie could carry you at five times or more the speed of sound, reaching the hypersonic range.

Relativity Space, a California-based aerospace manufacturer, has revealed a new rocket that is both 3D printed and fully reusable. The Terran R could serve as a competitor to SpaceX’s Falcon 9 and is planned for launch in 2024.

Virgin Galactic founder Richard Branson could fly to space just a bit earlier than Blue Origin and SpaceX’s founders.

Amazon founder’s brother, Mark, and one other person will join Bezos onboard Blue Origin vessel on 20 July.

The Amazon CEO looks set to beat his SpaceX rival on an important milestone — being the first rocket billionaire to space aboard a Blue Origin capsule.

Jeff Bezos plans to travel to space next month as one of the first passengers carried by Blue Origin, the Amazon.com Inc. founder’s space company.

Mr. Bezos said in an Instagram post Monday that he will be one of the inaugural passengers on Blue Origin’s New Shepard spacecraft, during its first crewed flight scheduled for launch from West Texas on July 20. Mr. Bezos said that his brother, Mark Bezos, will also be on board.

“I want to go on this flight because it’s a thing I’ve wanted to do all my life,” Mr. Bezos said in a video posted to Instagram. “It’s an adventure. It’s a big deal for me.”

Article I just wrote about how going to Mars is actually good for protecting life on Earth, too.

People often lump going to Mars or the Moon into a this/that fight when it comes to bettering the life of the Earth and its inhabitants. But, it’s not that simple.

The technology we master in the pursuit of space colonization (starti n g at the Moon and Mars / space stations) will serve to advance that on Earth. The things we learn will help provide a guide for what to do on this future planet, and not just life beyond it. Sure, in-situ resource utilization/production will generate rocket fuel on extraterrestrial bodies. But, things like the NASA Kilopower nuclear reactor can lay the groundwork for alternative energies deployed on Earth at scale. I imagine thorium reactors will follow suit while we still try to deploy fusion at a consumer scale and not just a research basis.
