Pic of the Week: Blue Ring Around the Crater

This week’s image may appear to be a mining pit in Arizona, but in fact it is a crater in Mar’s southern hemisphere. The blue dust near the top of the crater’s rim is frozen carbon dioxide. The image was taken from NASA’s Mars Reconnaissance Orbiter using its High Resolution Imaging Science Experiment.

Here is more information about the image from NASA:

Every winter, a layer of carbon dioxide frost (dry ice) forms on the surface of Mars. At its greatest extent in mid-winter, this frost reaches from the poles down to the middle latitudes, until it is too warm and sunny to persist. In most places this is around 50 degrees latitude, similar to the latitude of southern Canada on Earth.

However, small patches of dry ice are found closer to the equator on pole-facing slopes, which are colder because they receive less sunlight. This image was taken in the middle of winter in Mars’ Southern Hemisphere, and shows a crater near 37 degrees south latitude. The south-facing slope has patchy bright frost, blue in enhanced color. This frost occurs in and around the many gullies on the slope, and in other images, has caused flows in the gullies.

European/Russian Rover Coordination Now Dead

The European Space Agency (ESA) has decided to terminate cooperation with Russia on the ExoMars rover mission. The joint mission, planned for September 2022, was suspended earlier this year after Russia invaded Ukraine. The ESA has now cut all links on the project and hopes to work with NASA on some aspects of the mission.

The rover, named the Rosalind Franklin, would be the first European rover to visit Mars. It is designed to explore the surface of Mars as well as collect and analyse samples. The plan is to land the rover at a site with high potential for finding well-preserved organic material, particularly from the very early history of the planet.

Both Covid and the war in Ukraine have delayed the rover mission, but the ESA will see it through, alone if necessary, but hopefully with others. Maybe Russia can be a partner again in the future, but it will need new leadership that knows how to play well with others.

Video/Radio: Martian Life is “Not Bonkers”

Last week on the The Chris Moyles Show on Radio X, Dr. Brian Cox responded to a call in question about life on Mars. He noted that NASA’s Perseverance rover may find signs of life in an ancient river delta where it is now drilling. He said he would not be surprised if Martian microbes were located.

He also discussed plans to visit Jupiter’s moon Europa to explore its seas and look for life. Interestingly, he highlighted how Europa may contain three times as much water as can be found on the Earth. That would make it quite a rest stop for future solar system voyages.

In the end, he made it clear that finding life in our solar system is “not bonkers.” That said, he also explored the idea that we may be alone in this universe in terms of intelligent civilizations.

Television: More Space Stories This Summer

If you are looking for space series beyond the Moon, PBS has a few more shows for you. With the James Webb Space Telescope releasing the first photos next week, now is the time to brush up on the mission with a NOVA special. And check out the earlier NOVA piece on the planets as well. Dates and times may vary by region.

NOVA: Ultimate Space Telescope, July 13 at 9pm (28 minutes):

How did NASA engineers build and launch the most ambitious telescope of all time? Follow the dramatic story of the James Webb Space Telescope—the most complex machine ever launched into space. If it works, scientists believe that this new eye on the universe will peer deeper back in time and space than ever before to the birth of galaxies, and may even be able to “sniff” the atmospheres of exoplanets as we search for signs of life beyond Earth. But getting it to work is no easy task. The telescope is far bigger than its predecessor, the famous Hubble Space Telescope, and it needs to make its observations a million miles away from Earth—so there will be no chance to go out and fix it. That means there’s no room for error; the most ambitious telescope ever built needs to work perfectly. Meet the engineers making it happen and join them on their high stakes journey to uncover new secrets of the universe.

NOVA: The Planets, July 7 & 14 at 8pm (5 episodes)

Among the stars in the night sky wander the eight-plus worlds of our own solar system—each home to truly awe-inspiring sights. Volcanoes three times higher than Everest, geysers erupting with icy plumes, cyclones larger than Earth lasting hundreds of years. Each of our celestial neighbors has a distinct personality and a unique story. In this five-part series, NOVA will explore the awesome beauty of “The Planets,” including Saturn’s 175,000-mile-wide rings, Mars’ ancient waterfalls four times the size of any found on Earth, and Neptune’s winds—12 times stronger than any hurricane felt on our planet. Using unique special effects and extraordinary footage captured by orbiters, landers and rovers, we’ll treat viewers to an up-close look at these faraway worlds. We’ll stand on the dark side of Pluto, lit only by the reflected light of its moons, watch the sun set over an ancient Martian waterfall, and witness a storm twice the size of Earth from high above Saturn. And, we’ll reveal how each of them has affected our own planet: Earth. 

Podcast: Elon Musk on the Moon and More

On this week’s podcast program Sway, you can re-listen to a September 2020 interview between host Kara Swisher and Elon Musk. This was long before all the Twitter nonsense, when Mr. Musk was still focused on cars and space (mostly). The discussion covers plenty of topics, including the need to settle Mars (Mr. Musk disagress with Jeff Bezos who he said believes a space station will be enough to save humanity from an existential crisis), neural implants, and a return to the Moon.

You can tell the program is dated because Mr. Musk complains that NASA cannot find a way to return to the Moon, whereas today we have the Artemis lunar program that includes SpaceX as one of its contractors. Nonetheless, it is good to hear from the old Musk when he was a little more focused.

Then again, the neural implants still seem odd. Neuralink, a company he co-founded, is focusing on those with disabilities at the moment, but the application is expected to be more widespread:

Neuralink is currently focused on making medical devices. These devices have the potential to help people with a wide range of injuries and neurological disorders, and we hope to develop treatments for many of these conditions in the coming years. We expect that as our devices continue scale, and as we learn to communicate with more areas of the brain, we will discover new, non-medical applications for our [brain-machine interface] BMIs. Neuralink’s long-term vision is to create BCIs that are sufficiently safe and powerful that the general population would want to have them.

In a Fortune magazine article, “Elon Musk Claims Neuralink’s Brain Implants will ‘Save’ Memories Like Photos and Help Paraplegics Walk Again. Here’s a Reality Check,” the authors take him to task on his neural implant idea, stating:

Helping paraplegics walk and curing brain disorders are certainly noble goals. And, hey, ordering a pizza just by thinking about it sounds cool. But many experts are concerned that Musk is seriously overhyping what Neuralink’s implants will be able to accomplish.

Elon Musk overhyping an idea? Never!
