How would a piano sound on Mars? Embark on an interplanetary sonic journeyAeon Videos
If the Universe is born and no one is present to hear it, does it still make a sound? Well, theoretically, yes. As this video from the US filmmaker John D Boswell explores, where a ‘thick soup of atoms’ is present, sound is possible. Made in collaboration with the podcast Twenty Thousand Hertz, this short documentary deploys dramatic CGI visuals, a pulsing score and the voices of prominent scientists to explore the sounds of space – from those humanity has recorded to those we can only speculate about.

The Sounds of Space: A sonic adventure to other worldsYouTube
Space is more than just a feast for the eyes. It’s a feast for the ears. You just have to know where — and when — to look. Floating in the silent void of space are trillions of islands of sound, each with their own sonic flavor — some eerily familiar, some wildly different than Earth’s. And even space itself was once brimming with sound.

So, farewell then, Opportunity

15 years. That’s not bad at all.

NASA’s record-setting Opportunity Rover mission on Mars comes to end
Designed to last just 90 Martian days and travel 1,100 yards (1,000 meters), Opportunity vastly surpassed all expectations in its endurance, scientific value and longevity. In addition to exceeding its life expectancy by 60 times, the rover traveled more than 28 miles (45 kilometers) by the time it reached its most appropriate final resting spot on Mars – Perseverance Valley.

Nasa confirms Mars rover Opportunity is dead
“We had expected that dust falling out of the air would accumulate on the solar rays and eventually choke off power,” Callas said. “What we didn’t expect was that wind would come along periodically and blow the dust off the arrays. It allowed us to survive not just the first winter, but all the winters we experienced on Mars.”

A dust storm has killed NASA’s longest-lived Mars rover
In 2005, Opportunity overcame a sand trap and the loss of one wheel to arrive at the Victoria crater, a 2,400-foot hole that it explored for two years, finding features at its bottom again shaped by ancient water. It next explored the Endeavor crater, 13 miles away, starting in 2011. Most recently it had traversed a narrow valley leading down into the larger Endurance crater.

As this video from NASA shows, the Rover had been on an incredible trek these last 15 years.

Here’s xkcd’s surprisingly moving take on it.

Thanks for bringing us along.

Absolutely.

To the moon… and beyond!

Fresh from our trip to Kielder, my son’s very excited about this news story.

The lunar gateway: a shortcut to Mars?
“The moon has lain virtually undisturbed for the last 4.5bn years,” says Parker. “It is a museum of the history of our solar system. And yes, we visited it when we briefly landed Apollo spacecraft there. However, that was the equivalent of going to a museum, heading straight to the gift shop and then leaving. It is the dusty corners of a museum where you find the really interesting stuff – and that is where we are going to go with Gateway.”

And our boy’s keen to go, too, on his way to Mars. That may take some time, though.

How far is it to Mars?
If the Earth were 100 pixels wide, the moon would be 3000 pixels away. Mars, at its closest, would be 428,000 pixels away.

And who knows what else is out there.

The unending hunt for Planet Nine, our solar system’s hidden world
Astronomers are deeply divided, but intent on finding the truth. They’re using the world’s largest telescopes and most powerful supercomputers, and enlisting the help of thousands of amateurs like Forbes, who plays her part in this epic, astronomical search in between episodes of Love Island. Together, they will either pinpoint the location of this mysterious world and give the solar system a ninth planet, or rule out its existence once and for all.
