Study finds the minimum number of Martian settlers for survival is 110

Posted by in category: space

So you want to colonize Mars. Well, Mars is a long ways away, and in order for a colony to function that far from Earthly support, things have to be thought out very carefully. Including how many people are needed to make it work.

A new study pegs the minimum number of settlers at 110.

Going with a view? A spacewalk is the ‘best view for a bathroom,’ astronaut says

Posted by in category: space

Space is the “best view for a bathroom anywhere,” says one NASA astronaut.

A curious young student asked NASA astronaut Bob Behnken the question on everyone’s mind on Monday (June 29) during a series of televised media interviews: How do astronauts go to the bathroom in space?

Clearspace One: The First Attempt At Cleaning Up Space Junk | The State of Science

Posted by in categories: business, science, space

As mentioned in previous videos, space junk is a deadly threat to our GPS, telecommunications, and satellite infraustructure. As such, in this video, we will talk about humanity’s upcoming, first mission to attempt to clean up orbital debris: Clearspace One, which is commissioned by the ESA.

NASA Prepares to Explore the Moon: Spacesuits and Tools

Posted by in category: space

“Watching Apollo footage of astronauts doing geology on the surface of the Moon is a really great way to think about preparing for Artemis.” —Goddard scientist Kelsey Young.

Here’s how #NASA is preparing astronauts to do science on the Moon.

Calculating the speed of coronal mass ejections could avoid unneeded satellite shutdown

Posted by in categories: energy, space

Satellite operators could be doing more harm than good by shutting down their systems whenever a coronal mass ejection (CME) from the Sun is forecast to arrive at Earth, UK researchers have suggested. Mathew Owens, Mike Lockwood and Luke Barnard at the University of Reading show that the speeds and magnetic field intensities of the bursts could be just as important to consider as their arrival times when deciding when to turn satellite systems off. If applied, their ideas could significantly improve the efficiency of many satellite operations.

Originating from the Sun’s dynamic surface, CMEs are high energy bursts of plasma that travel through interplanetary space, accompanied by strong magnetic fields. When they interact with Earth’s atmosphere, they can trigger solar storms that cause severe damage to satellite systems if they are operating at the time. To predict these disruptions, astronomers measure the speed at which CMEs travel through space to make accurate forecasts of when they will arrive at Earth.

Currently, many satellite operators adopt a “better safe than sorry” approach when responding to these forecasts. Whenever a CME is predicted to arrive, they will completely shut down their systems to avoid any damage. However, the Reading trio argue that these current early warning systems do not account for a simple yet crucial fact: while all solar storms are triggered by CMEs, not all CMEs cause in damaging events.

Astronauts Finalize Preps Before Wednesday’s Battery Spacewalk

Posted by in category: space

The Expedition 63 crew is set for its second spacewalk on Wednesday at 7:35 a.m. EDT to continue upgrading International Space Station power systems.

Commander Chris Cassidy will lead the spacewalk and exit the Quest airlock in the U.S. spacesuit with the red stripes. He’ll be followed by Flight Engineer Bob Behnken in his spacesuit with no stripes.

Both astronauts are being joined today by Flight Engineer Doug Hurley as they finalize procedure reviews, organize tools and perform suit leak checks before tomorrow’s spacewalk. Hurley will be on duty helping the spacewalkers in and out their spacesuits and monitoring the excursion. Roscosmos cosmonaut Ivan Vagner will assist the NASA trio on Wednesday.

Habitat Mars: Learning to live sustainably on the red planet

Posted by in categories: engineering, habitats, space, sustainability

There’s quite a bit of buzz these days about how humanity could become a “multiplanetary” species. This is understandable, considering that space agencies and aerospace companies from around the world are planning on conducting missions to low earth orbit (LEO), the moon, and Mars in the coming years, not to mention establishing a permanent human presence there and beyond.

To do this, humanity needs to develop the necessary strategies for sustainable living in hostile environments and enclosed spaces. To prepare humans for this kind of experience, groups like Habitat Marte (Mars Habitat) and others are dedicated to conducting simulated missions in analog environments. The lessons learned will not only prepare people to live and work in space but foster ideas for sustainable living here on Earth.

Habitat Marte was founded in 2017 by Julio Francisco Dantas de Rezende, the professor of sustainability in the Department of Product Engineering at the Federal University of Rio Grande do Norte (UFRN) and the director of innovation with the Research Support Foundation (FAPERN). He is also the coordinator of Habitat Marte and Mars Society Brazil.

Graze’s solar-powered, self-driving mower is a view of Elon Musk’s fully-autonomous future

Posted by in categories: Elon Musk, food, robotics/AI, space, sustainability

Tesla’s Autonomy Day in April 2019 gave supporters of the company a look into Elon Musk’s vision of a fully-autonomous future. While the event featured the company’s strategies for the future as it prepares to “free investors from the tyranny of having to drive their own cars,” the $100 billion agriculture sector is also looking into sustainable, self-driving technologies that would revolutionize the industry.

Santa Monica, California-based lawn and landscaping startup Graze is developing a solar-powered, fully-autonomous lawn mower that requires no human interaction. The battery-operated, fully-autonomous mower is being developed by Graze CEO John Vay who has an extensive background in landscaping, and CTO Roman Flores whose past employers include NASA and the Caltech Curiosity Mars Rover Team. The two minds are developing the product in an attempt to revolutionize commercial agriculture as we know it.

Quantum Entanglement Demonstrated Aboard Orbiting CubeSat – Step Toward Space-Based Global Quantum Network

Posted by in categories: quantum physics, security, space

Advance poised to enable cost-effective space-based global quantum network for secure communications and more.

In a critical step toward creating a global quantum communications network, researchers have generated and detected quantum entanglement onboard a CubeSat nanosatellite weighing less than 2.6 kilograms and orbiting the Earth.

“In the future, our system could be part of a global quantum network transmitting quantum signals to receivers on Earth or on other spacecraft,” said lead author Aitor Villar from the Centre for Quantum Technologies at the National University of Singapore. “These signals could be used to implement any type of quantum communications application, from quantum key distribution for extremely secure data transmission to quantum teleportation, where information is transferred by replicating the state of a quantum system from a distance.”
