NASA’s X-59 Quesst supersonic commercial jet, which is being developed by Lockheed Martin, will have its flight test livestreamed as a demonstration of how quiet it can be in the air. The $247.5 million Quesst, whose name is short for Quiet SuperSonic Tech, will be shown on the livestream dramatically emerging from Lockheed Martin's Skunk Works facility in Palmdale, California. NASA has been on a mission since 2018 to prove that its X-59 can fly over cities without producing noise pollution, or sonic booms. This test flight marks an important milestone in the six-year-old project.
The first flight will be streamed on January 12 at 4pm ET on YouTube, as well as the NASA app and the NASA+ streaming service.
The space agency said it will survey people about the noises they hear from the jet during the first flight. It did not specify how it would find these people, or many people it would poll. The data collected will be sent to regulators and used to help propose new rules that limit the use of supersonic jets. The US federal government has blocked all civilian supersonic jets from flying over land for over five decades.
When NASA first announced its quiet supersonic technology project in 2018, administrator Jim Bridenstine said, “This aircraft has the potential to transform aviation in the United States.” While the jet was supposed to first take flight in 2021, the debut today still marks a major milestone in the QueSST mission. By 2027, NASA expects to have more definitive results about how effective the new aircraft technology is at reducing flight noise.
If new laws are eventually passed that permit supersonic jet aircrafts to fly in close proximity to land, high-speed commercial flights could become a reality. Once NASA and Lockheed Martin finalize development of the aircraft, the agency said it will conduct safety evaluations for about nine months. After enough evidence is shared to prove that the Quesst aircraft can be flown safely, NASA plans to expand its flight tests to cities across the US and collect more information about the noise it produces through additional surveys.

NASA is delaying its return to the Moon with the Artemis program. "To give Artemis teams more time to work through the challenges with first-time developments, operation and integration, we're gonna give more time on Artemis 2 and 3," NASA Administrator Bill Nelson told reporters on a call.
As such, Artemis 2, which had been scheduled for a November 2024 launch, is now targeting September 2025. That four-person mission is set to fly around the Moon, in a similar fashion to the uncrewed Artemis 1. As for Artemis 3, which will take humans back to the lunar surface for the first time since 1972, that's now targeted for September 2026, marking a nine-month delay.
Those are the only delays NASA has announced for now. Nelson said "Artemis 4 remains on track for September 2028." Along with a lunar landing, that mission will mark the delivery of a habitat module to the Lunar Gateway, a space station that's planned for lunar orbit.
In order to safely carry out our upcoming #Artemis missions to the Moon with astronauts, we are now targeting September 2025 for Artemis II and September 2026 for Artemis III.
The delays are for safety reasons. "For Artemis 2, there are new capabilities being on-ramped for the mission," Amit Kshatriya, deputy associate administrator of the Moon to Mars Program said. Those include propellant loading, crew loading and egress and fresh abort and life support systems.
Kshatriya said NASA is learning from both the data it obtained from Artemis 1 and the production of components for future missions. "From the test flight in particular, we had one major finding that we need a little bit more time to work [on] and that is the performance of the thermal protection system on the spacecraft, on the heat shield," Kshatriya said.
While the heat shield performed well overall during the Artemis 1 landing in terms of thermal protection, it experienced "some unexpected phenomena we need to make sure we understand perfectly," namely some charred material. NASA doesn't want to leave anything to chance when it comes to astronauts' safety and it spent "the bulk of 2023 investigating" that concern, Kshatriya noted. NASA hopes to identify the root cause of the issue in the spring.
Meanwhile, among other concerns, NASA encountered some issues with the life support system. "During the acceptance of some components for Artemis 3, we noticed a failure in some motor valve circuitry," Kshatriya said. "These components passed acceptance testing for Artemis 2, but did not pass them for Artemis 3. That gave us pause to stop and look at that circuit in a more detailed way." As such, NASA found a design flaw in the circuit.
Given its importance to the life support system, the agency deemed the system unacceptable as is. "We have to replace it to guarantee the safety of the crew," Kshatriya said. It's likely to take quite some time to resolve the issue as NASA will have to carefully test every change, but Kshatriya added the agency knows how to solve the problem.
The Artemis delays follow the failure of a mission that sought to transport the first US commercial payload to the Moon. Astrobotic had hoped to make a soft landing on the lunar surface with its Peregrine lander. However, due to some post-launch issues (in particular, a propellant leak) the soft landing is no longer possible.
"Given the propellant leak, there is, unfortunately, no chance of a soft landing on the moon. However, we do still have enough propellant to continue to operate the vehicle as a spacecraft," Astrobotic wrote on X. "The team continues to work to find ways to extend Peregrine's operational life."

The Peregrine spacecraft has experienced an ‘anomaly’ that could endanger its planned moon landing, as reported by the BBC.Astrobotic, the private company behind the project, says this anomaly prevents the spacecraft from pointing its solar panels at the sun. In other words, the vehicle can’t charge its battery. Without power, the planned lunar landing for February might have to be canceled.
Astrobotic engineers are working the problem and will provide updates as they become available. The launch itself went off without a hitch early this morning, as the issue popped up during post-launch checks after communications had been established. The team behind the launch suggest the most likely cause of the anomaly is a problem with propulsion. Unfortunately, the engineers have a limited window of time to troubleshoot and fix the issue, as the spacecraft’s battery is currently “reaching operationally low levels.” There was a short comms breakdown, but it looks like that issue has been resolved.
The company has also stated that the propulsion issue led to a "critical loss of propellant." Astrobotic has planned for a wide variety of fault scenarios and could get everything squared away before too long, but it's looking less likely by the minute. The company says it's still trying to stabilize the propellant loss, but is investigating "alternative mission profiles" and trying to save as much science and data as it can.
Peregrine is supposed to be the first American lunar lander to visit the moon in over 50 years. The United Launch Alliance’s new Vulcan Centaur rocket carried the craft out of the atmosphere. If it manages to touch down on the moon, Peregrine will become the first commercial craft to land on any planetary body outside of Earth.
Though not directly affiliated with NASA, the Peregrine launch is part of the space agency’s new Commercial Lunar Payload Services (CLPS) program. To that end, it’s supposed to deliver five payloads to the moon for NASA to help prepare for the upcoming Artemis missions. It’s also carrying a number of payloads for commercial clients at a cost of $1.2 million per kilogram. This cargo includes everything from mini rovers and science instruments to art collections and physical representations of cryptocurrency.
There’s also human remains on board, including the DNA of science fiction author Arthur C. Clarke. Peregrine is scheduled to land on the moon’s nearside, which faces Earth, on February 23, though that timeframe could change or disappear altogether. Ahead of the launch, CLPS Program Manager Chris Culbert acknowledged that a lunar landing was not guaranteed, stating that “landing on the moon is extremely difficult.”

Hours before sunrise on Monday morning, United Launch Alliance’s brand spankin’ new Vulcan Centaur rocket is scheduled to make its maiden flight carrying a historic passenger: Peregrine, the first American lunar lander to be sent to the moon in over 50 years. And its mission could mark a turning point in humankind’s exploration of the cosmos. Peregrine is not a NASA spacecraft, but one developed by Pittsburgh-based Astrobotic, a private company. If it survives touchdown, Peregrine will be the first commercial craft to successfully land on the moon — or any planetary body outside of Earth, for that matter.
Astrobotic is among a small group of companies that have been selected to carry out lunar deliveries for the space agency over the next few years as part of NASA’s new Commercial Lunar Payload Services (CLPS) program. Peregrine Mission 1, expected to launch January 8 at 2:18AM ET, is the first of these operations under a $79.5 million contract with the space agency. But it’s a wholly commercial endeavor, and alongside the five payloads it’ll deliver for NASA to support the upcoming Artemis missions, Peregrine will have cargo for other clients on board too, at a cost of $1.2 million per kilogram (roughly 2.2 pounds). That includes mini rovers and science instruments, collections of art and archival material, a physical “bitcoin” and, controversially, human remains.
Peregrine is headed for the moon’s nearside, the hemisphere that is always facing Earth. The 6-foot-tall, 8-foot-wide lander will (hopefully) touch down softly in a region named Sinus Viscositatis — the “Bay of Stickiness” — for the mysterious domes there that are thought to have been formed long ago by thick silicic lava. These peculiar features, called Gruithuisen Domes, don’t match up with the surrounding basaltic terrain, nor is the moon home to the ingredients so far known to give rise to silicic volcanoes.
Astrobotic
“The formation of the domes is a scientific mystery we are still working to understand,” said CLPS project scientist Paul Niles in a briefing on Thursday ahead of the launch. Peregrine will land near the domes on a patch of lunar mare, or the dark features created by hardened basaltic lava flows that we can see from Earth. The NASA payloads on board consist of a Laser Retroreflector Array (LRA), Neutron Spectrometer System (NSS), Linear Energy Transfer Spectrometer (LETS), Near InfraRed Volatiles Spectrometer System (NIRVSS) and Peregrine Ion-Trap Mass Spectrometer (PITMS). These instruments will gather data to help characterize the local environment.
“Three of our instruments will collect data on lunar volatiles using different techniques,” Niles said. “Two instruments will provide perspectives on the radiation environment at the lunar surface, helping us better prepare to send crewed missions back to the moon. We'll also learn information about the composition of the surface by evaluating its mineralogy.” Later, NASA will send another suite of instruments to the summit of Gruithuisen Domes.
As far as science deliveries are concerned, Peregrine will also carry a payload for Agencia Espacial Mexicana (AEM), the Mexican Space Agency. Its fleet of five mini rovers, each measuring just shy of 5 inches wide, will be the first Latin American science instruments to make it to the surface of the moon, according to Astrobotic. Carnegie Mellon University’s 4-pound Iris rover is hitching a ride on Peregrine too, with plans to snap photos that it’ll send back home. And the German Aerospace Center (DLR) is sending its M-42 radiation detector, which is intended to measure how much radiation a human would be exposed to on a roundtrip mission to the moon.
Among the non-science payloads, ULA’s Vulcan Centaur and Peregrine will be ferrying small portions of human remains for the space memorial companies Celestis and Elysium Space. Celestis has two separate memorial destinations planned for the trip: one, “Tranquility,” will land on the moon with Peregrine, while another, “Enterprise,” will continue on to deep space with the Centaur upper stage after it separates from the lunar lander. Flights like these that go beyond Earth’s immediate vicinity start at just under $13,000, and potential clients are given the option to send up symbolic amounts of either human ashes or DNA.
Astrobotic/ULA
One of the luminaries whose DNA is headed to the lunar surface will be 2001: A Space Odyssey co-writer and science fiction author, Arthur C. Clarke. On the Enterprise flight are the remains of several key figures from the Star Trek franchise, including series creator Gene Roddenberry, his wife, Majel Barrett Roddenberry, and their son Eugene “Rod” Roddenberry, plus Nichelle Nichols (Lt. Uhura of the original series) and her son, Kyle Johnson. Elysium has been less forthcoming about whose remains it’ll be sending.
There’s been some backlash about the idea of turning the moon into a memorial site. Navajo Nation President Buu Nygren spoke out against the upcoming mission after hearing about the plan, calling it “tantamount to desecration” for the many cultures who consider the moon to be sacred, Arizona Public Radio reported.
In response to questioning led by Reuters’ Joey Roulette during the NASA briefing on Thursday, members of the space agency repeatedly reiterated that the decision of which payloads to fly fell solely on Astrobotic. “They don't have to clear those payloads with us,” CLPS Program Manager Chris Culbert said. “These are truly commercial missions. It's up to them to sell what they can sell.”
The issue highlights one of the potential downsides to relying on contractors, and it’ll undoubtedly rear its head again as NASA leans more heavily on the commercial industry for future missions. While NASA may not be in the position to approve what payloads are included alongside its own on commercial missions, Culbert added that the teams “obviously have a lot of discussions about how the payloads fit together.”
The rest of the 20 total payloads are a mix of mementos and items representing Earth and the achievements of humanity. Astrobotic partnered with DHL to curate a “moonbox” of keepsakes that will fly with Peregrine, including items such as photographs, literature and even a chunk of Mount Everest. Hungary’s Puli Space Technologies and the UK’s SpaceBit are sending plaques to the lunar surface, while the Japanese space company Astroscale has filled a “Lunar Dream Capsule” with “185,872 messages from children from around the world.”
In addition to its rover, Carnegie Mellon created what it’s calling the “first museum on the moon.” The University’s MoonArk project, a small cylinder made up of four chambers that contain “hundreds of images, poems, music, nano-objects, mechanisms and samples from Earth,” will remain on the Peregrine lander where it can be appreciated by future visitors along with the other stationary objects on board. Similarly, Peregrine will carry the Arch Mission Foundation’s Lunar Library 2, which it calls “an ultra-durable archive of humanity.” Wikipedia is in there, as well as other major collections of Earthly information and human languages.
And, there are two bitcoin projects going to the moon with Peregrine because crypto is, apparently, inescapable: a physical bitcoin engraved with its private key, from the Seychelles cryptocurrency exchange BitMEX; and US-based BTC Inc.’s Bitcoin Magazine Genesis Plate, which includes a copy of the first block of bitcoin ever mined.
Once Peregrine reaches lunar orbit, it’ll remain there for a few weeks before making its attempt to land on the surface. That’s expected to happen on February 23. Considering the US hasn’t put a lander on the moon since the days of the Apollo mission, it’s a pretty big deal. But, it’s risky business. When it comes to moon landings, there have been far more unsuccessful attempts than successful ones. “Landing on the moon is extremely difficult,” Culbert said during NASA’s briefing. “We recognize that success cannot be ensured.”
Regardless, NASA and its commercial partners aim to keep trying, and in close succession at that. Peregrine Mission 1 will be followed by the second of NASA’s CLPS missions in February, led by Intuitive Machines. After that, there are plans for at least four more CLPS lunar launches before the end of 2024.

A few weeks ago, NASA’s robotic Mars explorers were given some time off from hard work while the agency waited out Mars solar conjunction, a natural phenomenon that could interfere with their communications. Leading up to the pause, the Curiosity rover was put in park — but its Hazard-Avoidance Cameras (Hazcams) kept snapping away. In a first for the rover, Curiosity recorded the passage of a Martian day over 12 hours from its stationary position, capturing its own shifting shadow on the landscape as the sun moves from dawn to dusk. It held onto the images until after the conjunction ended on November 25.
NASA/JPL-Caltech
Curiosity was given instructions to record the 12-hour sequences a few days before the conjunction began in mid-November, according to NASA. The idea was to see if it could catch any weather events that might crop up. That didn’t end up happening, but the images Curiosity snapped on November 8 are still pretty enchanting. They’ve been pieced together in two videos showing the view from its front and rear Hazcams.
Curiosity’s Hazcams are normally used to help drivers avoid terrain that could be dangerous to the rover. But with the rover parked ahead of its pause in duties from November 11 to November 25, the cameras were freed up for a bit of sight-seeing. Curiosity recorded from its position at the base of Mars’ Mount Sharp from 5:30AM to 5:30PM. It and the other Mars explorers have since resumed their normal activities.

NASA’s campaign to gather names for a sort of “message in a bottle” that will fly with its upcoming Europa Clipper mission closes after this weekend, so if you were hoping to participate but haven’t yet made your submission, you’d better hurry up and do so. The signatures will accompany a poem written for Europa by US Poet Laureate Ada Limón, which will be engraved in Limón’s handwriting on a metal plate attached to the spacecraft. Europa, one of Jupiter’s largest moons, is thought to have a deep saltwater ocean beneath its icy crust — and there, the conditions could be suitable for microbial life.
To enter the Message in a Bottle campaign, you just need to go to NASA’s website and fill out a short signup form. The deadline is tomorrow, December 31. So far, more than 2.4 million people have added their names. According to NASA, the names of everyone who participated will be stenciled in tiny, tiny letters onto microchips using an electron beam that can create lines of text smaller than 1/1000th the width of a human hair. These microchips will be affixed to the plate containing the poem.
The Europa Clipper spacecraft is scheduled to launch in October 2024, and it’ll be another six years from then before it reaches Jupiter’s orbit. Once there, it’ll investigate Europa’s potential habitability through a series of close flybys. Europa is one of an estimated 95 moons circling Jupiter and among the longest known to humanity.

Researchers from Linköping University in Sweden developed a ‘bioelectronic soil’ that can speed up the growth of plants in hydroponic spaces, or farms that grow plants without soil in environments made up of mostly water and a place for roots to attach. After integrating the engineered ‘eSoil’ into the framework where seedlings grow, researchers discovered that sending electrical signals through the soil made plants grow 50 percent more on average.
The eSoil is made up of organic substances mixed with a conductive polymer called PEDOT, which can be found in things like sensors and OLED displays. Eleni Stavrinidou, the supervisor of the study, told Engadget that the soil’s conductivity was necessary for stimulating the plant roots. In this particular study, the researchers examined the effect of sending signals to barley seedlings over the span of 15 days before harvesting them for analysis. Applying a voltage as small as 0.5V on the eSoil electrically stimulates the roots, Stavrinidou explained. This, in turn, resulted in a recordable increase in the biomass of the electrically stimulated plants when compared to the non-stimulated seedings.
The stimulation’s effect on the barley seedlings was described as “steady” and “transient.” Stavrinidou told Engadget that nitrogen, one of the main nutrients involved in plant growth, was processed more efficiently through the stimulation. "We found that the stimulated plants could process the nutrients more efficiently however we don't understand how the stimulation is affecting this process,” Stavrindou explained, adding that the reason behind the growth process will be a focus of future studies.
PNAS
While hydroponic techniques are mainly used to grow leafy greens and some vegetables like cucumbers and tomatoes, the eSoil could offer a solution to create new ways to increase crop yields in commercial settings and especially in places where environmental conditions impact plant growth. The study highlights that this technique could minimize the use of fertilizers in farming.
The opportunity for technological innovation in farming is huge considering the number of US farms has steadily declined since 1982, according to the Department of Agriculture. Last year, the number of US farms reached 2 million, down from 2.2 million in 2007. Not only are farms on the decline, but the US is losing acres of land due to a host of reasons that range from climate change to worsening economic outlook for farmers due to inflation, making farming in controlled environments more popular.
But beyond improving crop yield, the implementation of eSoil in hydroponic farms could make them more energy-conscious. While traditional hydroponic farms use up less water, they require more energy to run. “The eSoil consumes very little power in the microwatt range,” Stavrinidou said. Before this technology can be applied to large-scale agriculture and other types of crops, more studies need to be conducted to observe how electrical stimulation can impact the whole growth cycle of a plant throughout its entire lifespan and not just in the early stages of seedling maturation. Stavrinidou also said that her team plans on studying how the technique affects the growth of other plant species.

In a successful demonstration of new laser communications capabilities, NASA beamed an ultra-high definition video across 19 million miles of space from its Psyche spacecraft to Earth earlier this month. It’s the first time a UHD streaming video has been sent from deep space via laser. The history-making video? A 15-second clip of an orange cat named Taters chasing a laser dot.
The signal from the video, sent on December 11, made it to Earth in 101 seconds from Psyche’s location at the time, which was about 80 times as far as the distance between Earth and the moon. It was uploaded before the mission launched, and sent back home by a flight laser transceiver aboard Psyche at a rate of 267Mbps. The spacecraft, which set off on its journey in October, is on its way to study a metal-rich asteroid in the main asteroid belt between Mars and Jupiter.
“Despite transmitting from millions of miles away, it was able to send the video faster than most broadband internet connections,” said Ryan Rogalin, the receiver electronics lead for the project at NASA’s Jet Propulsion Lab. “In fact, after receiving the video at Palomar, it was sent to JPL over the internet, and that connection was slower than the signal coming from deep space.”
