Volunteer Crew to Exit NASA’s Simulated Mars Habitat After 378 Days

The four volunteers who have been living and working inside NASA’s first simulated yearlong Mars habitat mission are set to exit their ground-based home on Saturday, July 6. NASA will provide live coverage of the crew’s exit from the habitat at NASA’s Johnson Space Center in Houston at 5 p.m. EDT.

NASA will stream the activity, which will include a short welcome ceremony, on NASA+, NASA Television, the NASA app, the agency’s website, and NASA Johnson’s X and Facebook accounts. Learn how to stream NASA TV through a variety of platforms, including social media.

The first Crew Health and Performance Exploration Analog (CHAPEA) mission began in the 3D printed habitat on June 25, 2023, with crew members Kelly Haston, Anca Selariu, Ross Brockwell, and Nathan Jones. For more than a year, the crew simulated Mars mission operations, including “Marswalks,” grew and harvested several vegetables to supplement their shelf-stable food, maintained their equipment and habitat, and operated under additional stressors a Mars crew will experience, including communication delays with Earth, resource limitations, and isolation.

How NASA and SpaceX get spacecraft safely back on Earth

Water has a relatively low viscosity – that is, it deforms fast under stress – and it has a density much lower than hard rock. These two qualities make it ideal for landing spacecraft. But the other main reason water works so well is because it covers 70% of the planet’s surface, so the chances of hitting it are high when you’re falling from space.

The science behind splashdown is complex, as a long history proves.

In 1961, the U.S. conducted the first crewed splashdowns in history. These used Mercury reentry capsules.

Video: SpaceX testing chopsticks to catch Super Heavy rocket falling from space

The ambitious plan involves catching the falling Super Heavy boosters using the launch tower’s “chopstick” arms. This innovative approach aims to revolutionise rocket recovery and enhance the reusability of the company’s Starship system.

Recent footage shared by SpaceX showcases tests of the chopstick mechanism at their Starbase facility in Texas. The company has been observed clamping the tower arms around a portion of a Super Heavy booster to evaluate the system’s parameters.

This testing is crucial for verifying the forces the chopsticks will need to withstand during an actual catch attempt.

The 5th Industrial Revolution

In this episode of the 5th Industrial Revolution VODcast we sit down with Dr. Jordan Okie of Arizona State University School of Earth and Space Exploration to discuss a key relevancy to the next industrial revolution, sustainability, through the lens of Dr. Okie’s area of expertise: Ecology and Biology. Our key takeaways: We are in a race against time and extinction. We will need to find a way to evolve through technology to survive, be it here on Earth or in our exploration of Space.

Quantum effects forbid the formation of black holes from high concentrations of intense light, say physicists

For the last seven decades, astrophysicists have theorized the existence of “kugelblitze,” black holes caused by extremely high concentrations of light.

These special black holes, they speculated, might be linked to astronomical phenomena such as , and have even been suggested as the power source of hypothetical spaceship engines in the far future.

However, new research by a team of researchers at the University of Waterloo and Universidad Complutense de Madrid demonstrates that kugelblitze are impossible in our current universe. Their research, titled “No black holes from ,” is published on the arXiv preprint server and is forthcoming in Physical Review Letters.

First Nigerian set to fly to space for free

Expensive, risky and elite — that’s space travel in a nutshell ever since Yuri Gagarin became the first human to be sent to space 63 years ago. Till now, less than 700 astronauts have reached space altitude and a majority among them have been from just three countries. Even commercial space flights remain exclusive to the few who can afford them.

But not anymore. Giving regular folks from around the world a chance to become astronauts and participate in space science, US-based Space Exploration and Research Agency (SERA) has partnered with Jeff Bezos’ Blue Origin to develop what they call “a human spaceflight programme for citizens of all nations”. The cost will be borne by SERA, and co-founders Sam Hutchison and Joshua Skurla say they might even be tapping talent from India for their programme.

In line with this mission to make space accessible, SERA has just signed an agreement to send the first Nigerian to space. In June 2022, Victor Hespanha, a 28-year-old civil engineer from Brazil, was selected to travel to space onboard Blue Origin’s New Shepard Rocket (NS-22). He was only the second Brazilian astronaut, and soon became a national hero.
