Canoo made a cute trio of EVs to carry NASA’s Artemis 2 astronauts to the SLS

Electric vehicle startup Canoo has delivered its first shipment to NASA. This week, a trio of the company’s Crew Transportation Vehicles (CTVs) arrived at the Kennedy Space Center in Florida. Although they look like they’re made for exploring the surface of the Moon, the vans are designed to carry astronauts to the KSC’s launch pads, starting with NASA’s forthcoming Artemis 2 mission.

According to Canoo, the vans, based on the company’s existing lifestyle vehicle design, can carry fully-suited astronauts, as well as flight support crew and any equipment they may need. “The vehicles have an exclusive interior and exterior design that will provide astronaut and crew comfort and safety while on the nine-mile journey to the launch pad at Kennedy Space Center,” the company said, adding it would share interior shots of the vehicles later this year.

The Artemis 2 mission will see NASA launch its first crewed mission to the Moon since the end of the Apollo program in 1972. Four astronauts will travel around the satellite during the 10-day flight. During Artemis 2, NASA plans to conduct additional tests of its Orion capsule and Space Launch System (SLS) super heavy-lift rocket to ensure both spacecraft are safe for future crewed missions to the lunar surface.

As for Canoo, this is a chance for the automaker to drum up interest for its EVs. In May 2022, the company warned investors it was running low on cash. Since then, it announced an agreement with Walmart to provide the retailer with 4,500 EVs. The company also delivered a test vehicle to the US Army. Still, even with those deals in place, it has a long way to go before achieving financial sustainability.

Researchers find evidence of organic matter on Mars

The Perseverance Rover has found evidence of organic compounds in the Jezero Crater on Mars. Although this isn’t the smoking gun proving once and for all that Mars once hosted life — these compounds could have also developed in nonbiological ways — the results hint at surprisingly complex organic conditions for the “key building blocks for life” on Earth’s neighbor. The study was published in Nature.

The Perseverance Rover, the first to explore the Jezero Crater, has been investigating the area since February 2021. Researchers believe the basin once housed an ancient lake, including a delta from a river that once flowed into it. It’s one of the most likely regions to reveal leftover signs of life on Mars.

Organic molecules like those observed in the Jezero Crater contain carbon and often hydrogen atoms. They’re the core components of life as we know it on Earth, although they can also develop abiologically. “They are an exciting clue for astrobiologists since they are often thought of as building blocks of life,” paper co-author Joseph Razzell Hollis, a postdoctoral fellow at London’s Natural History Museum, said toNewsweek. “Importantly, they can be created by processes not related to life as we know it, and so organic molecules are not evidence of life on their own without sufficient extra evidence that cannot be explained by nonbiological — or abiotic — processes.”

The rover observed the compounds using an instrument — the Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals (SHERLOC) — that maps organic molecules and minerals on rock surfaces. Significantly, it found organic materials in all ten targets it observed on the crater floor. “Our results support observations by previous robotic missions to Mars that the Red Planet was once rich in organic material, compounds made primarily of carbon and hydrogen, and that some of that organic material can still be detected billions of years later,” co-author Joseph Razzell Hollis, a London-based astrobiologist, toldGizmodo. “Each detection, each observation, gives us a little bit more information that brings us closer to understanding the history of Mars and whether it could have supported life in the past.”

Now that the researchers have observed the molecules, they’ll need a better look at them in Earthbound labs to draw further conclusions about their origins. “If these samples are returned to terrestrial laboratories, a more diverse suite of tools can be used to study the samples, including at higher spatial resolution and with much greater specificity and sensitivity,” the authors wrote. They’ll have to wait for the Mars Sample Return (MSR) mission, which isn’t expected to launch from Earth until at least the late 2020s. Still, the trip should be worth the wait. “So far, the only Martian rocks we’ve ever been able to study on Earth have been meteorites. Getting our hands on intact Mars rocks, carefully stored and protected from contamination, will be invaluable to planetary science,” Razzell Hollis told Newsweek.

James Webb telescope marks first anniversary with an image of a nearby stellar nursery

It’s hard to believe, but the James Webb Space Telescope started sending out stunning images of the universe one full year ago. To commemorate the milestone, NASA's letting the telescope do what it does best, showing us obscenely cool space shots. The latest and greatest image depicts a (relatively) nearby region of space that’s a galactic nursery of sorts, with 50 young stars that could one day form systems that resemble our own.

The Rho Ophiuchi cloud complex is approximately 390 light years from Earth, which is peanuts when compared to the vastness of space, though it would still take 14,500,000 years of travel to get there using current technology. The stars shown in the image are mostly similar in mass to our beloved sun and some even boast the beginnings of circumstellar disks, which are the swirling rings of gas and dust where planets are born.

NASA

So what are those gorgeous red swirls? Those are huge jets of molecular hydrogen, which occur when a star bursts through its natal envelope of cosmic dust and stretches out into the universe for the very time. New life is beautiful, and red. Mostly red.

“Webb’s image of Rho Ophiuchi allows us to witness a very brief period in the stellar life cycle with new clarity. Our own sun experienced a phase like this, long ago, and now we have the technology to see the beginning of another’s star’s story,” said project scientist Klaus Pontoppidan.

The James Webb Space Telescope has been dropping hit after hit throughout this past year. There was the first image of an interstellar asteroid belt, a harrowing scene depicting the Pillars of Creation, a picture of an early-universe galaxy cluster and so much more. It still hasn’t found aliens though. What’s up with that?

NASA expands developers' contracts for its next-gen spacesuits

In 2022, NASA chose Axiom Space and Collins Aerospace to develop next-gen spacesuits meant to finally replace the decades-old gear astronauts are using to this day. Now, the space agency has expanded their existing contracts and is giving them $5 million apiece to design and develop new spacesuits not included in the original orders they received. 

NASA has ordered a spacesuit from Axiom Space meant for use in Low Earth Orbit, specifically for spacewalks outside the International Space Station. The original contract for Axiom was for a spacewalking system that the Artemis III astronauts will wear on the lunar surface when they land on the moon. Axiom unveiled a prototype for its original order in March, showcasing a suit with joints that allow wearers to move around with ease and a helmet equipped with a light and an HD camera. 

Meanwhile, Collins Aerospace has received an order for a spacesuit meant for use on the lunar surface. The company was previously contracted to develop a spacewalking suit for use outside the ISS. In other words, each company has received a new order that mirrors the other's previous one. Lara Kearney, manager of the Extravehicular Activity and Human Surface Mobility Program at NASA’s Johnson Space Center in Houston, said:

"These task orders position NASA for success should additional capabilities become necessary or advantageous to NASA’s missions as the agency paves the way for deep space exploration and commercialization of low Earth orbit. Using this competitive approach we will enhance redundancy, expand future capabilities, and further invest in the space economy."

Redundancy is an important part of space tech development. In this case, spacesuits meant for the same purpose developed by two different companies could ensure that astronauts will have something to use if the other one fails for any reason. That said, the new task orders are for the companies' initial "design modification work" — they're essentially modifying their original suits for a new purpose — and NASA wants to see them first before committing to their continued development. Axiom told SpaceNews that if NASA decides to push through with the new spacesuits' development, the full order will cost the agency $142 million over four years.

James Webb telescope captures the most distant active supermassive black hole yet

The James Webb space telescope has given scientists the capability to discover celestial objects they wouldn't have been able to otherwise, such as ancient galaxies that theoretically shouldn't exist. Now, as part of the Cosmic Evolution Early Release Science (CEERS) Survey, researchers have discovered the most distant active supermassive black hole we've seen to date. 

Thanks to the near- and mid-infrared images James Webb has taken, researchers were able to find a supermassive black hole in the galaxy they've dubbed CEERS 1019. They were also able to determine that the black hole has existed merely 570 million years after the Big Bang and that it's around 9 million solar masses. In addition, the data provided by the telescope allowed them to come to the conclusion that the black hole is eating up a lot of gas and churning out new stars. "A galaxy merger could be partly responsible for fueling the activity in this galaxy's black hole, and that could also lead to increased star formation," CEERS team member Jeyhan Kartaltepe of the Rochester Institute of Technology in New York explained. In the image below, you can see CEERS 1019 appearing as three bright clumps.

At 9 million solar masses, this black hole is much smaller than other active supermassive black holes previously discovered. Those celestial objects typically contain more than 1 billion times the mass of the sun, which makes them much brighter and easier to detect. The CEERS 1019 black hole is more similar to the one in the center of our galaxy, which is around 4.6 million times the mass of the sun. NASA said scientists have long known that smaller black holes must have existed earlier in the universe, but it wasn't until James Webb became operational that they were able to confirm their presence. 

In fact, the CEERS Survey team also found two other ancient but small black holes through their data. The CEERS 746 black hole existed 1 billion years after the Big Bang, while the CEERS 2782 black hole has been around since 1.1 billion years after the event. When viewed through other instruments, these black holes appear as ordinary star-forming galaxies. Astronomers are also reviewing other more distant black holes found using James Webb's data at the moment, so CEERS 1019 might lose the record sooner rather than later.

CEERS team lead Steven Finkelstein from the University of Texas at Austin said: "Until now, research about objects in the early universe was largely theoretical. With Webb, not only can we see black holes and galaxies at extreme distances, we can now start to accurately measure them. That’s the tremendous power of this telescope."

Scientists still find it difficult to explain how this black hole formed so soon after the universe began. But in the future, Webb's data could give them the information they need to be able to figure out how early black holes are formed.

Europe’s Euclid space telescope launches to map the dark universe

On late Saturday morning, a SpaceX Falcon 9 rocket carrying the European Space Agency’s Euclid spacecraft successfully lifted off Cape Canaveral, Florida. The near-infrared telescope, named after the ancient Greek mathematician who is widely considered the father of geometry, will study how dark matter and dark energy shape the universe.

In addition to a 600-megapixel camera astronomers will use to image a third of the night sky over the next six years, Euclid is equipped with a near-infrared spectrometer and photometer for measuring the redshift of galaxies. In conjunction with data from ground observatories, that information will assist scientists with estimating the distance between different galaxies. As The New York Times notes, one hope of physicists is that Euclid will allow them to determine whether Albert Einstein’s theory of general relativity works differently on a cosmic scale. There’s a genuine possibility the spacecraft could revolutionize our understanding of physics and even offer a glimpse of the ultimate fate of the universe.

“If we want to understand the universe we live in, we need to uncover the nature of dark matter and dark energy and understand the role they played in shaping our cosmos,” said Carole Mundell, the ESA’s director of science. “To address these fundamental questions, Euclid will deliver the most detailed map of the extra-galactic sky.”

With Euclid now in space, it will travel approximately a million miles to the solar system’s second Lagrange point. That’s the same area of space where the James Webb Space Telescope has been operating for the past year. It will take Euclid about a month to travel there, and another three months for the ESA to test the spacecraft’s instruments before Euclid can begin sending data back to Earth.

NASA is creating a ChatGPT-like assistant for astronauts

Despite our intrinsic distrust of AI in space taught to us by movies like 2001: A Space Odyssey ("I'm afraid I can't do that, Dave"), it offers large advantages to both manned and unmanned missions. To that end, NASA is developing a system that will allow astronauts to perform maneuvers, conduct experiments and more using a natural-language ChatGPT-like interface, The Guardian reported. 

"The idea is to get to a point where we have conversational interactions with space vehicles and they [are] also talking back to us on alerts, interesting findings they see in the solar system and beyond," said Dr. Larissa Suzuki, speaking at an IEEE meeting on next-gen space communication. "It's really not like science fiction anymore." 

NASA aims to deploy the system on its Lunar Gateway, a space station that will orbit the Moon and provide support for NASA's Artemis mission. It would use a natural language interface that allows astronauts to seek advice on experiments or conduct maneuvers without diving into complex manuals. 

On a dedicated page soliciting small business support for Lunar Gateway, NASA wrote that it would require AI and machine learning technologies to manage various systems when it's unoccupied as well. Those include autonomous operations of science payloads, data transmission prioritization, autonomous operations, health management of Gateway and more.

For instance, Suzuki outlined a scenario in which the system would automatically fix data transmission glitches and inefficiencies, along with other types of digital outages. "We cannot send an engineer up in space whenever a space vehicle goes offline or its software breaks somehow," she said.

NASA is recycling 98 percent of astronaut pee and sweat on the ISS into drinkable water

NASA has achieved a technological milestone that could one day play an important role in missions to the Moon and beyond. This week, the space agency revealed (via Space.com) that the International Space Station’s Environmental Control and Life Support System (ECLSS) is recycling 98 percent of all water astronauts bring onboard the station. Functionally, you can imagine the system operating in a way similar to the Stillsuits described in Frank Herbert’s Dune. One part of the ECLSS uses “advanced dehumidifiers” to capture moisture the station’s crew breaths and sweat out as they go about their daily tasks.

Another subsystem, the imaginatively named “Urine Processor Assembly,” recovers what astronauts pee with the help of vacuum distillation. According to NASA, the distillation process produces water and a urine brine that still contains reclaimable H20. The agency recently began testing a new device that can extract what water remains in the brine, and it’s thanks to that system that NASA observed a 98 percent water recovery rate on the ISS, where previously the station was recycling about 93 to 94 percent of the water astronauts were bringing aboard.

“This is a very important step forward in the evolution of life support systems,” said NASA’s Christopher Brown, who is part of the team that manages the International Space Station’s life support systems. “Let’s say you collect 100 pounds of water on the station. You lose two pounds of that and the other 98 percent just keeps going around and around. Keeping that running is a pretty awesome achievement.”

If the thought of someone else drinking their urine is causing you to gag, fret not. “The processing is fundamentally similar to some terrestrial water distribution systems, just done in microgravity,” said Jill Williamson, NASA’s ECLSS water subsystems manager. “The crew is not drinking urine; they are drinking water that has been reclaimed, filtered, and cleaned such that it is cleaner than what we drink here on Earth.”

According to Williamson, systems like the ECLSS will be critical as NASA conducts more missions beyond Earth's orbit. “The less water and oxygen we have to ship up, the more science that can be added to the launch vehicle,” Williamson said. “Reliable, robust regenerative systems mean the crew doesn’t have to worry about it and can focus on the true intent of their mission.”

Saturn’s moon Enceladus could support species similar to Earth

Saturn’s moon Enceladus has phosphorous. The finding came from recently analyzed icy particles emitted from the natural satellite’s ocean plumes, detected by NASA’s Cassini spacecraft. The discovery means Enceladus has all the chemical building blocks for life as we know it on Earth. “This is the final one saying, ‘Yes, Enceladus does have all of the ingredients that typical Earth life would need to live and that the ocean there is habitable for life as we know it,” Morgan Cable, astrobiology chemist at NASA’s Jet Propulsion Laboratory, toldThe Wall Street Journal.

Cassini, which plunged to its demise in Saturn’s atmosphere in 2017, collected data by passing through Enceladus’ continually erupting geysers at its south pole and Saturn’s E ring, also containing escaped particles from the moon. Beneath its icy crust, Enceladus has a warm subsurface ocean, over 30 miles deep, enveloping the entire moon. The eruptions at its south pole spit icy particles into space, allowing research crafts like Cassini to study the ocean’s chemical makeup without taking a dip or even touching the moon’s surface.

NASA

Data from previous missions indicated the moon had all of life’s essential building blocks — carbon, hydrogen, nitrogen, oxygen and sulfur — except for phosphorous. A team of planetary scientists found nine grains containing phosphate (phosphorous bound to oxygen atoms) among around 1,000 samples initially overlooked by researchers. The tiny amount detected reflects phosphorous’ scarcity. “Of the six bioessential elements, phosphorus is by far the rarest in the cosmos,” said Frank Postberg, the study’s lead author.

Of course, Enceladus containing the requirements for life doesn’t necessarily mean life exists on the moon. “The next step is to figure out if indeed it is inhabited, and it is going to take a future mission to answer that question,” Cable said. “But this is exciting, because it makes Enceladus an even more compelling destination to go and do that kind of search.” NASA will get a chance to learn more when the Dragonfly mission heads for Saturn’s moon Titan in 2027; another proposed mission could arrive at Enceladus around 2050. In addition, the James Webb Space Telescope may help further to illuminate the chemical breakdown of Enceladus’ warm subterranean ocean.

Latest Webb Telescope images gives a look at stars being born in the Virgo constellation

It seems like every few weeks, NASA, the European Space Agency (ESA) and the Canadian Space Agency (CSA) drop an impressive image from the James Webb Space Telescope that is both stunning to behold and advances our knowledge of the universe. The latest is of the barred spiral galaxy NGC 5068, called a "barred" galaxy because of the bright central bar you can see in the upper left of the above image. It's a combination image consisting of infrared shots taken from the telescope's MIRI (Mid-Infrared Instrument) and NIRCam (Near-Infrared Camera) sensors. 

What those sensors captured is a galaxy in the Virgo constellation about 20 million light-years from Earth, and because the JWST can see through the dust and gas that surrounds stars as they're born, the instrument is particularly suited to producing images that show the process of star formation.

Looking at the two individual images that make up the composite reveals different layers of the galaxy. As Gizmodo notes, the image produced by the MIRI sensor provides a view of the galaxy's structure and the glowing gas bubbles that represent newly formed stars.

ESA/Webb, NASA & CSA, J. Lee and

The second image, taken from the NIRCam, put the focus on a huge swath of stars in the foreground. The composite, meanwhile, shows both the enormous amount of stars in the region as well as the highlights of the stars that have just been "born."

ESA/Webb, NASA & CSA, J. Lee and

There isn't one specific breakthrough finding in this image; instead, NASA notes that this is part of a wider effort to collect as many images of star formation from nearby galaxies as it can. (No, 20 million light-years doesn't exactly feel nearby to me, either, but that's how things go in space.) NASA pointed to another few images as other "gems" from its collection of star births, including this impressive "Phantom Galaxy" that was shown off last summer. As for what the agency hopes to learn? Simply that star formation "underpins so many fields in astronomy, from the physics of the tenuous plasma that lies between stars to the evolution of entire galaxies." NASA goes on to say that it hopes the data being gathered of galaxies like NGC 5068 can help to "kick-start" major scientific advances, though what those might be remains a mystery.
