Astronomers have used NASA’s Hubble Space Telescope to uncover a vast, complex dust structure, about 150 billion miles across, enveloping the young star HR 4796A. A bright, narrow, inner ring of dust is already known to encircle the star and may have been corralled by the gravitational pull of an unseen giant planet. This newly discovered huge structure around the system may have implications for what this yet-unseen planetary system looks like around the 8-million-year-old star, which is in its formative years of planet construction.

Astronaut Scott Tingle Was Able To Control A Ground-Based Robot… From Space. If something called “Project METERON” sounds to you like a sinister project involving astronauts, robots, the International Space Station, and artificial intelligence, I don’t blame you. Because that’s what it is (except for the sinister part.) In fact, the Meteron Project (Multi-Purpose End-to-End Robotic Operation Network) is not sinister at all, but a friendly collaboration between the European Space Agency (ESA) and the German Aerospace Center (DLR.) The idea behind the project is to place an artificially intelligent robot here on Earth under the direct control of an astronaut 400 km above theRead More →

Carnival of Space #551 This week’s Carnival of Space is hosted by Brian Wang at his Next Big Future blog. Click here to read Carnival of Space #551 And if you’re interested in looking back, here’s an archive to all the past Carnivals of Space. If you’ve got a space-related blog, you should really join the carnival. Just email an entry to susie@wshcrew.space, and the next host will link to it. It will help get awareness out there about your writing, help you meet others in the space community – and community is what blogging is all about. And if you really want to help out, sign upRead More →

Comets which consist of two parts, like Chury, can form after a catastrophic collision of larger bodies. Such collisions may have taken place in a later phase of our solar system, which suggests that Chury can be much younger than previously assumed. This is shown through computer simulations by an international research group with the participation of the University of Bern. Powered by WPeMaticoRead More →

Engineers Develop a Whole New Way to Use Curiosity’s Drill After a Recent Hardware Failure Since it landed on Mars in 2012, the Curiosity rover has used its drill to gather samples from a total of 15 sites. These samples are then deposited into two of Curiosity’s laboratory instruments – the Sample Analysis at Mars (SAM) or the Chemistry and Mineralogy X-ray Diffraction (CheMin) instrument – where they are examined to tell us more about the Red Planet’s history and evolution. Unfortunately, in December of 2016, a key part of the drill stopped working when a faulty motor prevented the bit from extending and retractingRead More →

Saturn Photobombs a Picture of the Martian Moon Phobos The ESA’s Mars Express probe has been studying Mars and its Moons for many years. While there are several missions currently in orbit around Mars, Mars Express‘s near-polar elliptical orbit gives it some advantages over the others. For one, its orbital path takes it closer to Phobos than any other spacecraft, which allows it to periodically observe the moon from distances of around 150 km (93 mi). Because of this, the probe is in an ideal position to study Mars’ moons and capture images of them. On occasion, this allows for some interesting photo opportunities. ForRead More →

Book Review: Inventing a Space Mission Inventing a Space Mission Where will science’s next big advance arise? Like Archimedes, maybe someone will jump up out of a tub of hot water, shout ‘Eureka’ and direct everyone to use the next great discovery. Or maybe some science-bureaucrats will gather together via some on-line meeting tool and choose to chase down the most promising opportunity. Given that experiments seem to be getting harder and harder to undertake, then it’s no surprise that one hugely successful space observatory arose from the latter. This is the main message of the book “Inventing a Space Mission – the Story ofRead More →
