It’ll take about seven months to send humans to Mars using today’s spaceships. That’s not exactly a quick jaunt, but it is doable.

Trips to other planets could take years, though, and if we want to explore the rest of our solar system — or the places beyond it — we’re going to need a faster way to travel.

Now, a physicist has designed a new rocket thruster that could potentially allow humans to travel 10 times faster in space — and it’s inspired by nuclear fusion.

“If we make life multiplanetary, there may come a day when some plants & animals die out on Earth, but are still alive on Mars,” Musk tweeted in mid-April.

What Musk probably didn’t know was that his destiny was already sealed. Not in the stars, but on paper.

In 1,953 a book was published that predicted plans for an “Elon” to take humans to Mars.

High-energy cosmic rays have proven elusive… but we may have found their source.


Thanks to new research led by the University of Nagoya, scientists have quantified the number of cosmic rays produced in a supernova remnant for the first time. This research has helped resolve a 100-year mystery and is a major step towards determining precisely where cosmic rays come from.

While scientists theorize that cosmic rays originate from many sources — our Sun, supernovae, gamma-ray bursts (GRBs), and active galactic nuclei (sometimes called quasars) — their exact origin has been a mystery since they were first discovered in 1912. Similarly, astronomers have theorized that supernova remnants (the after-effects of supernova explosions) are responsible for accelerating them to nearly the speed of light.

As they travel through our galaxy, cosmic rays play a role in the chemical evolution of the interstellar medium (ISM). As such, understanding their origin is critical to understanding how galaxies evolve.

The 36th Space Symposium began with an opening ceremony honoring outstanding individuals and organizations in the space community.

Among the honorees, the team behind NASA’s Ingenuity Mars Helicopter received the John L. “Jack” Swigert, Jr. Award for Space Exploration. The annual award recognizes extraordinary accomplishments by a company, space agency, or consortium of organizations in the realm of space exploration and discovery.

Also, Bill Ingalls, a senior contract photographer at NASA received the 2021 Douglas S. Morrow Public Outreach Award. For over three decades Ingalls has been capturing NASA’s most spectacular moments through his camera lens. His iconic photos have captured Neil Armstrong’s burial at sea, Space Shuttle Endeavor’s final landing in 2,011 and the first launch of a US citizen on a Russian rocket.

The Space Symposium brings together space leaders from around the world to discuss, address and plan for the future of space. It runs from Aug. 23 to 26 in Colorado Springs, Colorado.
