NASA probe finds new asteroid during flyby

Posted by in category: space

Dinkinesh, previously thought to be a single asteroid, is revealed by NASA’s Lucy probe to in fact be a binary pair.

Dinkinesh, a main-belt asteroid with an orbital period of 3.2 years, was discovered on 4th November 1999 by the Lincoln Near-Earth Asteroid Research (LINEAR) sky survey at Socorro, New Mexico. Less than two weeks after being observed, astronomers lost track of the object and it went unrecognised for several years. Additional sightings occurred in the mid-2000s, helping to re-establish its position and greatly reduce the uncertainties of its orbit.

Titan and Ganymede Revealed: Understanding Shear Deformation on Icy Moons

Posted by in categories: materials, space

“We are interested in studying shear deformation on icy moons because that type of faulting can facilitate the exchange of surface and subsurface materials through shear heating processes, potentially creating environments conducive for the emergence of life,” said Dr. Liliane Burkhard.


Two recent studies published in Icarus examine tectonic processes known as shear stresses which are also referred to as strike-slip faults on Saturn’s largest moon, Titan, and Saturn’s largest moon, Ganymede. While such processes are common on Earth, specifically with the San Andreas Fault in northern California, and have been observed on several icy moons throughout the solar system, these two studies hope to shed new light on the inner workings that cause these processes to occur on Titan and Ganymede, the latter of which is the largest moon in the solar system.

Seven Sweltering Exoplanets Found in Kepler Data

Posted by in category: space

“We’ve assembled the most accurate list of Kepler planet candidates and their properties to date,” said Dr. Jack Lissauer. “NASA’s Kepler mission has discovered the majority of known exoplanets, and this new catalog will enable astronomers to learn more about their characteristics.”


Though NASA’s Kepler space telescope officially “retired” in October 2018, scientists are still pouring over data from the iconic exoplanet hunter that operated for more than nine years. Most recently, scientists came upon data that added four more exoplanets to the Kepler-385 system, which is located approximately 4,700 light-years from Earth and had previously been known to contain three exoplanets, all of which were discovered in 2014.

Chatbots May ‘Hallucinate’ More Often Than Many Realize

Posted by in categories: robotics/AI, space

When summarizing facts, ChatGPT technology makes things up about 3 percent of the time, according to research from a new start-up. A Google system’s rate was 27 percent.

When the San Francisco start-up OpenAI unveiled its ChatGPT online chatbot late last year.

When Google introduced a similar chatbot several weeks later, it spewed nonsense about the James Webb telescope. The next day, Microsoft’s new Bing chatbot offered up all sorts of bogus information about the Gap, Mexican nightlife and the… More.

PROJECT HYPERION: THE HOLLOW ASTEROID STARSHIP — DISSEMINATION OF AN IDEA

Posted by in categories: materials, space

A large space mirror heats up an asteroid, slowly melting it. Water, which was injected into the center of the body expands, blows up the melted material, creating the shape of a balloon. After cooling down, rotation is induced into the hollow body creating artificial gravity. An artificial fusion Sun brings daylight to the dark interior. A team of bio-life-support system experts, urban planners, and ecologists starts to create an artificial world inside the balloon, preparing it for the first settlers. The small world is then provided with a propulsion system and launched to one of the next stars or used as a space colony.

Tesla to integrate Elon Musk’s new AI assistant in its vehicles

Posted by in categories: Elon Musk, robotics/AI, space, sustainability

Tesla is going to integrate Elon Musk’s newly launched Grok AI assistant in its electric vehicles, according to the CEO.

Earlier this year, Musk launched a new AI startup, xAI, and said that it will work closely with Tesla.

The company’s mission is “to understand the true nature of the universe”, but in practice, its first project is to build a chatbot or AI assistant à la ChatGPT.

Wearables may save astronauts in space from deadly disorientation

Posted by in categories: space, wearables

They’re called vibrotactors and they vibrate to provide orientation cues.

A number of factors, such as the lack of gravity, changed sensory inputs, and the unique conditions of space travel, can cause disorientation in astronauts. This phenomenon is so severe that it can even be deadly to the space dwellers.

TESS Finds Eight More Super-Earths

Posted by in category: space

NASA’s Kepler spacecraft has discovered most of the confirmed exoplanets that we know of. But its successor, TESS (Transiting Exoplanet Survey Satellite), is catching up. New research announces the validation of eight more TESS candidates, and they’re all Super-Earths.

TESS’s planet-hunting mission has a more refined goal than its predecessor, Kepler. TESS was specifically built to detect exoplanets transiting in front of bright stars in Earth’s neighbourhood. It’s found about 400 confirmed exoplanets, but there’s a list of exoplanets awaiting confirmation that contains almost 6,000 candidates. There are only two ways to confirm all these exoplanets-in-waiting: further observations and statistical methods.

What all those unconfirmed candidates amount to is data. They’re hiding in TESS’s data, waiting for clever scientists to validate them. Further observations can help uncover them, but not alone.
