The three billionaires are locked in a race to reach space — but some future visions look more promising than others.

Shenzhou-12 manned spacecraft and Long March 2F Y12 carrier rocket were rolled out to the launch pad on Wednesday, the China Manned Space Engineering Office (CMSEO) said. Pre-launch preparations for the mission are underway.
The three astronauts who will take the Shenzhou-12 manned spacecraft to China’s Tianhe space station core cabin in June are now under Level-2 quarantine, with all related work having entered a final sprint stage, Yang Liwei, director of the China Manned Space Engineering Office and the country’s first astronaut revealed.
Yang, who went into space in the Shenzhou-5 craft on October 15, 2003, made the remarks during an interview with state broadcaster China Central Television (CCTV) on Saturday, following the successful launch of the Tianzhou-2 cargo craft earlier in the day.
According to Yang, the three astronauts of the Shenzhou-12 mission, who were selected from China’s first and second batch of astronauts, will stay in space for three months, during which they will conduct tasks including repair and maintenance, appliance switch and scientific operation of payloads.
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.
🛰 Space is a trip. Let’s explore it together.
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.”

# *A lovely single step bio-inspired process with some interesting complex benefits particularly for humans on Mars.*

A team led by UC Riverside engineers has developed a catalyst to remove a dangerous chemical from water on Earth that could also make Martian soil safer for agriculture and help produce oxygen for human Mars explorers.
Perchlorate, a negative ion consisting of one chlorine atom bonded to four oxygen atoms, occurs naturally in some soils on Earth, and is especially abundant in Martian soil. As a powerful oxidizer, perchlorate is also manufactured and used in solid rocket fuel, fireworks, munitions, airbag initiators for vehicles, matches and signal flares. It is a byproduct in some disinfectants and herbicides.
Because of its ubiquity in both soil and industrial goods, perchlorate is a common water contaminant that causes certain thyroid disorders. Perchlorate bioaccumulates in plant tissues and a large amount of perchlorate found in Martian soil could make food grown there unsafe to eat, limiting the potential for human settlements on Mars. Perchlorate in Martian dust could also be hazardous to explorers. Current methods of removing perchlorate from water require either harsh conditions or a multistep enzymatic process to lower the oxidation state of the chlorine element into the harmless chloride ion.
Doctoral student Changxu Ren and Jinyong Liu, an assistant professor of chemical and environmental engineering at UC Riverside’s Marlan and Rosemary Bourns College of Engineering, took inspiration from nature to reduce perchlorate in water at ambient pressure and temperature in one simple step.
