This hopping robot with flailing legs could explore asteroids in the future

Posted on by

Over the past two-and-a-half years, a group of students from ETH Zurich have been developing a robot with three spindly legs that was designed to be able to hop like an insect in microgravity. That's right — the curious little machine was built for space, specifically for the exploration of small celestial bodies like asteroids and moons. SpaceHopper, as the robot is called, could thus provide us more information to advance our understanding of life's origin, of the origin of water on our planet and of asteroids as potential providers of valuable resources. 

It has no preferred orientation, so it can go in any direction, and it has nine motors that give it the capability to jump long distances in low-gravity environments. The robot can even self-right after landing, ensuring the safety of any scientific payload it may carry. Since SpaceHopper was made for use on asteroids and moons, which have very little gravity compared to Earth, it has to be tested under conditions similar to those environments first. To see if it will actually work as intended, the students and the European Space Agency have recently taken the robot on a parabolic flight that creates a zero gravity environment when the aircraft freefalls. Apparently, they had no idea if SpaceHopper would be able to move as they intended in zero gravity scenarios and seeing that it actually worked was a "massive weight off [their] shoulders."

You can watch SpaceHopper flail about in the test flight below:

ESA’s Gaia mission discovers the biggest stellar black hole in our galaxy yet

Posted on by

In addition to the supermassive black hole at the center of our galaxy, the Milky Way also serves as home to smaller stellar black holes that form when a massive star collapses. Scientists believe there are 100 million stellar black holes in our galaxy alone, but most of them have yet to be discovered. The ones that had already been found are, on average, around 10 times the size of our sun, with the biggest one reaching 21 solar masses. Thanks to the information collected by the European Space Agency's Gaia mission, though, scientists have discovered a stellar black hole that's 33 times the size of our sun, making it the biggest one of its kind we've ever seen in our galaxy so far. It's also relatively close to our planet at around 1,926 light-years away. 

Gaia BH3, as it's now called, was first noticed by a team of ESA scientists poring over data from the mission to look for anything unusual. An old giant star from the nearby Aquila constellation caught their attention with its wobbling, leading to the discovery that it was orbiting a massive black hole. BH3 was hard to find despite being so close — it's now the second closest known black hole to our planet — because it doesn't have celestial bodies close enough that could feed it matter and make it light up in X-ray telescopes. Before its discovery, we'd only found black holes of comparable size in distant galaxies. 

The ESA team used data from ground-based telescopes like the European Southern Observatory to confirm the size of the newly discovered celestial body. They also published a paper with preliminary findings before they release a more detailed one in 2025, so that their peers could start studying Gaia BH3. For now, what they know is that the star orbiting it has very few elements heavier than hydrogen and helium, and since stellar pairs tend to have similar compositions, the star that collapsed to form BH3 could've been the same. 

Scientists have long believed that it's the metal-poor stars that can create high-mass black holes after they collapse, because they lose less mass in their lifetimes. In other words, they'd theoretically still have a lot of materials left by the time of their death to form a massive black hole. This was apparently the first evidence we've found that links metal-poor stars with massive stellar black holes, and it's also proof that older giant stars developed differently than the newer ones we see in our galaxy. 

We'll most likely see more detailed studies about binary systems and stellar black holes that use data from BH3 and its companion star in the future. The ESA believes that BH3's discovery is just the beginning, and it's going to be the focus of more investigations as we seek to unravel the mysteries of the universe.

NASA confirms its space trash pierced Florida man’s roof

Posted on by

On March 8, a piece of space debris plunged through a roof in Naples, FL, ripped through two floors and (fortunately) missed the son of homeowner Alejandro Otero. On Tuesday, NASA confirmed the results of its analysis of the incident. As suspected, it’s a piece of equipment dumped from the International Space Station (ISS) three years ago.

NASA’s investigation of the object at Kennedy Space Center in Cape Canaveral confirmed it was a piece of the EP-9 support equipment used to mount batteries onto a cargo pallet, which the ISS’ robotic arm dropped on March 11, 2021. The haul, made up of discarded nickel-hydrogen batteries, was expected to orbit Earth between two to four years (it split the difference, lasting almost exactly three) “before burning up harmlessly in the atmosphere,” as NASA predicted at the time. Not quite.

The roof-piercing debris was described as a stanchion from NASA flight support equipment used to mount the batteries onto the cargo pallet. Made of the metal alloy Inconel, the object weighs 1.6 lbs and measures 4 inches tall and 1.6 inches in diameter.

Otero told Fort Meyers CBS affiliate WINK-TV that he was on vacation when his son told him that an object had pierced their roof. “I was shaking,” he said. “I was completely in disbelief. What are the chances of something landing on my house with such force to cause so much damage. I’m super grateful that nobody got hurt.”

NASA says it will investigate the equipment dump’s jettison and re-entry to try to figure out why the object slammed into Otero’s home instead of disintegrating into flames. “NASA specialists use engineering models to estimate how objects heat up and break apart during atmospheric re-entry,” the space agency explained in a news release. “These models require detailed input parameters and are regularly updated when debris is found to have survived atmospheric re-entry to the ground.”

Most space junk moves extremely fast, reaching up to 18,000 mph, according to NASA. It explains, “Due to the rate of speed and volume of debris in LEO, current and future space-based services, explorations, and operations pose a safety risk to people and property in space and on Earth.”

Physicist Peter Higgs, who predicted ‘the God particle’, has died at 94

Posted on by

Peter Higgs, the physicist who predicted the Higgs boson particle, has passed away at the age of 94 due to a blood disorder. His work proposing the particle — and showing how it helped give mass to some matter — won him the Noble price in 2013. The Higgs boson is informally referred to as the God particle, after a book by Nobel laureate Leon Lederman.

Higgs came up with the idea in the early 1960s as an attempt to explain why atoms have mass in the first place. The research didn’t get any traction in scientific journals, primarily because few understood the concept, but he was finally published in 1964. This was just a theory at the time, but led to a 50-year race to prove the Higgs boson particle actually exists.

Scientists hit pay dirt in 2012, thanks to physicists working at the Large Hadron Collider at CERN in Switzerland. It took four years of experiments, but the Higgs boson particle was finally discovered, proving his ideas and adding a major puzzle piece to the corpus of particle physics knowledge known as the Standard Model.

As a matter of fact, modern theoretical physicists have posited the existence of up to five Higgs boson particles that fill up what is now called the Higgs field. Scientists hope to use the Higgs boson to one day find proof for ever-elusive dark matter.

The Royal Swedish Academy of Sciences, which awards the Nobel, wrote about the importance of his discovery ahead of the ceremony in 2013. “Even when the universe seems empty this field is there. Without it, we would not exist, because it is from contact with the field that particles acquire mass.” The Nobel was shared with François Englert, a Belgian theoretical physicist whose work in 1964 contributed to the discovery.

"At the beginning I had no idea whether a discovery would be made in my lifetime”, Higgs once said. He leaves two sons, Chris and Jonny, his daughter-in-law Suzanne and two grandchildren. His former wife Jody, a linguistics professor, died in 2008.

One of these concept lunar vehicles could join NASA’s Artemis V astronauts on the moon

Posted on by

Three companies are vying for the opportunity to send their own lunar vehicle to the moon to support NASA’s upcoming Artemis missions. The space agency announced this week that it’s chosen Intuitive Machines, Lunar Outpost and Venturi Astrolab to develop their lunar terrain vehicles (LTV) in a feasibility study over the next year. After that, only one is expected to be selected for a demonstration mission, in which the vehicle will be completed and sent to the moon for performance and safety tests. NASA is planning to use the LTV starting with the Artemis V crew that’s projected to launch in early 2030.

The LTV that eventually heads to the moon’s south pole needs to function as both a crewed and uncrewed vehicle, serving sometimes as a mode of transportation for astronauts and other times as a remotely operated explorer. NASA says it’ll contract the chosen vehicle for lunar services through 2039, with all the task orders relating to the LTV amounting to a potential value of up to $4.6 billion. The selected company will also be able to use its LTV for commercial activities in its down time.

Intuitive Machines, which will be developing an LTV called the Moon Racer, has already bagged multiple contracts with NASA as part of the Commercial Lunar Payload Services (CLPS) program, and in February launched its first lander, Odysseus, to the moon to achieve the first commercial moon landing. Venturi Astrolab will be developing a vehicle it’s dubbed Flex, while Lunar Outpost will be working on an LTV called Lunar Dawn. All must be able to support a crew of two astronauts and withstand the extreme conditions of the lunar south pole. 

 “We will use the LTV to travel to locations we might not otherwise be able to reach on foot, increasing our ability to explore and make new scientific discoveries,” said Jacob Bleacher, a chief exploration scientist at NASA.
