Dangerous solar blast detected at Mars by Chinese Orbiter in new episode of Robots In Space!🇹🇳🟠.

Join aerospace engineer Mike DiVerde as he breaks down groundbreaking research on Mars radiation from multiple space missions. This comprehensive analysis combines data from Tianwen-1, MAVEN, ExoMars, and the Curiosity rover to understand the dangerous Solar Energetic Particles affecting Mars. Learn why radiation protection is crucial for future Mars colonization and astronaut safety and discover how space weather impacts potential Mars habitats. DiVerde explains complex space science concepts in an accessible way, drawing from recent research that highlights the challenges of keeping humans safe on Mars. Essential viewing for anyone interested in Mars exploration and the future of human space missions.

The fact that the cold, dry Mars of today had flowing rivers and lakes several billion years ago has puzzled scientists for decades. Now, Harvard researchers think they have a good explanation for a warmer, wetter ancient Mars.

Building on prior theories describing the Mars of yore as a hot again, cold again place, a team led by researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have determined the chemical mechanisms by which ancient Mars was able to sustain enough warmth in its early days to host water, and possibly life.

“It’s been such a puzzle that there was on Mars, because Mars is further from the sun, and also, the sun was fainter early on,” said Danica Adams, NASA Sagan Postdoctoral Fellow and lead author of the new paper in Nature Geoscience.

A spy presses a button on their suit and blinks out of sight. A wizard wraps himself in a cloak and disappears. A star pilot flicks a switch, and their ship vanishes into space. Invisibility is one of the most tantalizing powers in fiction, spanning all kinds of stories. But could this fantasy ever become a reality? Max G. Levy digs into the technologies that could make invisibility possible.

Lesson by Max G. Levy, directed by Michalis Kalopaidis, Zedem Media.

SPHEREx could, though (in a way).

To be fair, SPHEREx won’t rival the JWST’s ability to observe highly localized regions of the universe that are confined to the infrared section of the electromagnetic spectrum. However, unlike the JWST, it is an all-sky survey. Whereas the $10 billion JWST is great at observing things like specific nebulas and relatively narrow but tremendously dimensional deep fields, SPHEREx is intended to image the entire sky as seen from Earth.

“We are literally mapping the entire celestial sky in 102 infrared colors for the first time in humanity’s history, and we will see that every six months,” said Nicky Fox, associate administrator for NASA’s Science Mission Directorate. “This has not been done before on this level of color resolution for our old sky maps.”

In the future we will build outposts and bases in space and on distant worlds, but what if we could make it so they built themselves instead?

MIT scientists are building ElectroVoxels, small, smart, self-assembling robots designed for space.

It’s programmable matter, infinitely recyclable large-scale 3D printing, if you will, and it could be the future of robotics and machinery in space. In this TechFirst, I chat with MIT PhD student Martin Nisser.

The idea of traveling through interstellar space using spacecraft propelled by ultrathin sails may sound like the stuff of sci-fi novels. But in fact, a program started in 2016 by Stephen Hawking and Yuri Milner, known as the Breakthrough Starshot Initiative, has been exploring the idea. The concept is to use lasers to propel miniature space probes attached to “lightsails” to reach ultrafast speeds and eventually our nearest star system, Alpha Centauri.

Caltech is leading the worldwide community working toward achieving this audacious goal.

“The will travel faster than any previous spacecraft, with potential to eventually open interstellar distances to direct spacecraft exploration that are now only accessible by remote observation,” explains Harry Atwater, the Otis Booth Leadership Chair of the Division of Engineering and Applied Science and the Howard Hughes Professor of Applied Physics and Materials Science at Caltech.
