After each use of one of the tools at the end of the Perseverance rover’s arm, the mission’s engineering team always takes images of the tool to make sure everything is still in working order.
Last week the rover’s drill was used to take a core sample from a rock – the 12th such sample that has now been stored and sealed for possible future retrieval in a proposed sample return mission. The team then took images of the drill and sample collection system components. In those images, two small pieces of debris were visible: a small object on the coring bit (which is stored in the bit carousel) and a small hair-like object on the drill chuck.
For a spacecraft that’s traveled millions of kilometers across space and driven on the surface of Mars, Curiosity is holding up pretty darned well. That’s the assessment from the operations team at NASA Jet Propulsion Laboratory. This week they celebrated ten years of the rover’s exploration across one of the more forbidding terrains in the solar system.
South Korea launched its first robotic mission to the Moon last week, as a SpaceX Falcon 9 successfully launched the Danuri Lunar Pathfinder mission on August 4, 2022 from Florida’s Cape Canaveral Space Force Station.
The spacecraft was placed into a fuel-saving lunar transfer orbit, and it should arrive in lunar orbit in December.
Way back in the earliest ages of the universe, the first galaxies were born. Astronomers want to know more about them. They’re especially interested to know exactly when these distant galaxies formed and what their stars were like. Now that JWST is a working observatory, astronomers are excited to use its data to explore those early epochs. They’re eager to see the most distant objects, and—as seems likely—do a rejiggering of the cosmic timeline after the Big Bang.
When the first humans reach Mars, they’ll probably live in habitats that were there ahead of time or in habs made from their landers. Eventually, though, if people are going to settle on Mars in large numbers, they’ll need to become self-sufficient. A group of researchers at Swinburne University in Melbourne, Australia is looking at ways to make it happen. Their goal is in-situ resource utilization on the planet for solutions to building out the materials needed for Mars cities. They’ve come up with a proposal to produce metals for use on Mars, using only what’s available on the planet. It’s the first detailed study of its kind focused on metal production at another world. It has further implications for colonies on the Moon, as well.
In the near future, NASA and other space agencies will send astronauts beyond Low Earth Orbit (LEO) for the first time in over fifty years. But unlike the Apollo Era, these missions will consist of astronauts spending extended periods on the Moon and traveling to and from Mars (with a few months of surface operations in between). Beyond that, there’s also the planned commercialization of LEO and cis-Lunar space, meaning millions of people could live aboard space habitats and surface settlements well beyond Earth.
This presents many challenges, which include the possibility that the sick and injured won’t have licensed medical practitioners to perform potentially life-saving surgery. To address this, Professor Shane Farritor and his colleagues at the University of Nebraska-Lincoln’s (UNL) Nebraska Innovation Campus (NIC) have developed the Miniaturized In-vivo Robotic Assistant (MIRA). In 2024, this portable miniaturized robotic-assisted surgery (RAS) platform will be flown to the International Space Station (ISS) for a test mission to evaluate its ability to perform medical procedures in space.
Wow, what a beauty! While we’ve all turned our attentions to the new James Webb Space Telescope, this image proves Hubble has still has got it where it counts.
This new image from the Hubble Space Telescope shows the heart of the globular cluster NGC 6638 in the constellation Sagittarius. This star-studded cluster contains tens of thousands to millions of stars, all tightly bound together by gravity. Globular clusters have a higher concentration of stars towards their centers, and this observation highlights that density.
While NASA’s much-lauded Space Launch System stands ready for its maiden flight later this month with the goal of sending astronauts back to the Moon in the next few years, our gazes once again turn to the stars as we continue to ask the question that has plagued humankind since time immemorial: Are we alone? While there are several solar system locales that we can choose from to conduct our search for life beyond Earth, to include Mars and Saturn’s moons, Titan and Enceladus, one planetary body orbiting the largest planet in the solar system has peaked the interest of scientists since the 1970s.
The OSIRIS-REx spacecraft conducted a two-year reconnaissance and sample collection at the asteroid Bennu, providing crucial data about the 500-meter-wide potentially hazardous rubble pile/space rock. When OSIRIS-REx arrived on Dec. 3, 2018, it needed some tricky navigation and precise maneuvers to make the mission work.
Experts at NASA Goddard’s Scientific Visualization Studio created an amazing visualization of the path the spacecraft took during its investigations. A short film called “A Web Around Asteroid Bennu” highlights the complexity of the mission, and the film is being shown at the SIGGRAPH computer graphics conference in Vancouver, British Columbia, Canada, a festival honoring standout works of computer animated storytelling.
Ask astronomers about dark matter and one of the things they talk about is that this invisible, mysterious “stuff” permeates the universe. In particular, it exists in halos surrounding most galaxies. The mass of the halo exerts a strong gravitational influence on the galaxy itself, as well as on others in the neighborhood. That’s pretty much the standard view of dark matter and its influence on galaxies. However, there are problems with the idea of those halos. Apparently, some oddly shaped dwarf galaxies exist that look like they have no halos. How could this be? Do they represent an observationally induced challenge to the prevailing ideas about dark matter halos?
