On their way around the Moon, the Artemis II crew had time to snap some terrific pictures of our blue planet. NASA has begun sharing the images, including the one above, which shows a striking view of Earth through the Orion capsule's window.
Artemis II Commander Reid Wiseman overcame the crew’s problems with Microsoft Outlook and the toilet to capture the photos. He took the above pic after the craft completed its translunar injection burn on April 2.

Meanwhile, this second photo trades clever composition for a full-on view of our planet. If you look carefully, you can see two auroras: one on the top right and another on the bottom left. Easier to spot is the diffuse glow of zodiacal light (bottom right) as the Earth eclipses the Sun.
At the time of publication, Artemis II is over 105,000 miles from Earth. The 10-day journey will have the crew of four looping around the Moon and back again. Serving largely as a test run for future deep space travel, the mission is NASA's first to the Moon since the Apollo program. However, the crew won't be landing this time; that will have to wait for Artemis IV, currently planned for 2028.

The Integrity, the name of the Orion capsule carrying Artemis II astronauts on a trip around the moon, has left Earth’s orbit. NASA has announced that it has successfully completed a key burn of Orion’s main engine. That six-minute firing of the engine provided approximately 6,000 pounds of thrust, which gave the spacecraft the acceleration it needed to set it on its path to the moon. “Today, for the first time since Apollo 17 in 1972, humans have departed Earth orbit,” said Dr. Lori Glaze from NASA Headquarters in Washington. “Orion is operating with crew for the first time in space, and we are gathering critical data, and learning from each step.” Commander Reid Wiseman called seeing “the entire globe from pole to pole” after leaving Earth’s orbit a “spectacular moment.”
Artemis II launched on April 1 at 6:35PM Eastern time after a couple of delays caused by a hydrogen leak and then a helium issue. It’s the first crewed flight of the Artemis program and the first time humanity has ventured beyond Low Earth Orbit after the Apollo program shut down. Within a few hours after its launch, the astronauts reported an issue with their onboard toilet, which crew member Christina Koch eventually fixed. Commander Wiseman then reported to mission control that they were having problems with Microsoft Outlook on the Surface Pro device they were using. But they were ultimately manageable setbacks that wouldn’t prevent the crew from achieving the mission’s goal.
The mission is taking NASA astronauts Reid Wiseman, Victor Glover and Christina Koch, as well as Canadian Space Agency astronaut Jeremy Hansen, on a 10-day trip around the moon. On April 6, the spacecraft will pass by the far side of the moon that humans have never directly seen before, and the crew will take photographs, as well as provide their own observations of the lunar surface.

The Artemis II mission successfully launched into space on April 1, at 6:35pm Eastern time, from Launch Complex 39B at the Kennedy Space Center in Florida. It will take NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, as well as Canadian Space Agency astronaut Jeremy Hansen, on a 10-day trip around the moon. This mission is the first crewed Artemis flight and will lay the groundwork for future trips to the moon itself, the first flight with a crew onboard the SLS rocket and Orion spacecraft system and our first foray into deep space since the Apollo program.
A few hours into their journey, and the astronauts could already see majestic views of our planet. However, the astronauts also reported a problem with their waste‑management system, which is the first real toilet installed on a deep-space mission. The astronauts thankfully have a backup option: Waste collection bags that Apollo crews had used and had previously discarded on the lunar surface.

By 10:43PM Eastern, the Orion spacecraft carrying the four astronauts successfully separated from the upper stage of the Space Launch System rocket. Glover then started manually piloting the capsule to demonstrate and test how Orion would move and dock with the future lunar landers that will be built by SpaceX and Blue Origin. You can watch the events that happened within the first few hours of the mission below. The crew and their Orion capsule are expected to slash down into the Pacific Ocean on April 10.

Artemis II, the first crewed mission under the Artemis program, is scheduled to launch today, April 1. NASA is opening a two-hour window for its lift off, starting at 6:24 PM Eastern time, at the Kennedy Space Center in Florida. The agency said the forecast for launch day “shows an 80 percent chance of favorable weather conditions” and that, on March 31, its engineers had finished critical health checks on the Space Launch System rocket that the mission will use.
On the evening of March 31, the engineers shifted the launch system into its final configuration. In the early hours of April 1, they will activate the ground launch sequencer. You can start watching Artemis II’s launch event at 7:45AM ET when the Artemis team will load propellant into the SLS rocket. Full launch coverage begins at 12:50 PM ET on NASA+, Amazon Prime or the YouTube video embedded below.
The Artemis II mission will take NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, as well as Canadian Space Agency astronaut Jeremy Hansen on a 10-day trip around the moon. It will be NASA’s first flight with a crew onboard the SLS rocket and Orion spacecraft system, and it will be humanity’s first foray into deep space since the Apollo program. During their 10-day mission, the astronauts will observe how journeys beyond Earth’s orbit affect human health. Artemis II was supposed to launch in February, but the attempt had failed due to a hydrogen leak. Another attempt in March was delayed yet again due a helium issue. If the launch doesn’t take place today as planned, NASA’s next launch opportunity is on April 6.

SpaceX has lost contact with Starlink satellite 34343 after it suffered an unspecified anomaly on March 29 while it was in orbit, the company has announced on X. The event happened while the satellite was approximately 348 miles above our planet. Since that is a relatively low altitude, SpaceX’s analysis showed that the remains of the satellite pose no risk to the International Space Station or the upcoming launch of the Artemis II mission. It also won’t affect the company’s Transporter-16 mission, which launched with small satellites from its clients on March 30.
In its statement, SpaceX also said that it will monitor any trackable debris, indicating that the satellite is no longer in one piece. LeoLabs, an American company tracking satellites in Low Earth Orbit, said it detected a “fragment creation event” involving Starlink 34343 on March 29. It also mentioned that this event is similar to another incident that happened on December 17, 2025. SpaceX had lost Starlink satellites to events like geomagnetic storms in the past, but it doesn’t seem like these two recent incidents were caused by external factors. The company has yet to announce what led to the anomalies, but LeoLabs believes that both of them were “likely caused by an internal energetic source rather than a collision with space debris or another object.”
At the moment, the Starlink team is still working on determining the root cause of the incidents. SpaceX said that once it has come to a conclusion, the company will “rapidly implement any necessary corrective actions.”
On Sunday, March 29, Starlink satellite 34343 experienced an anomaly on-orbit, resulting in loss of communications with the satellite at ~560 km above Earth.
Latest analysis shows the event poses no new risk to the @Space_Station, its crew, or to the upcoming launch of NASA’s…

The first crewed mission of NASA's Artemis moon program may take off in a matter of days, with a launch window that opens on April 1, and as preparations are underway for that, the space agency is refocusing its plan to establish a human presence on the moon. NASA announced major changes to its approach for moon landings that are expected to play out over the coming years, including axing its plan to build an orbiting station called Gateway. Read on to learn more about the agency’s new vision for the moon, along with other interesting science stories from this week.
Gateway out, moon base in
Just a few weeks after overhauling its Artemis program, NASA this week announced even more changes to its plans for putting astronauts back on the moon. Most notably, the space agency is abandoning the lunar Gateway project, which was intended to be the first ever space station orbiting the moon. Gateway, an international collaboration, wasn't just going to support exploration of the lunar surface, but deep space missions too. But the writing has been on the wall for some time; in the Trump administration's proposed budget cuts last May, Gateway was among the programs selected for the chopping block. Now, NASA is officially putting it on "pause" and plans to build a $20 billion moon base instead.
“NASA is committed to achieving the near‑impossible once again, to return to the moon before the end of President Trump’s term, build a moon base, establish an enduring presence, and do the other things needed to ensure American leadership in space," NASA Administrator Jared Isaacman said at the agency's Ignition event on Tuesday.
There are three phases to the moon base plan, according to NASA: first using contractors to send rovers and instruments to the moon through the Commercial Lunar Payload Services (CLPS) program; next establishing "semi-habitable infrastructure," with astronauts on the ground and collaboration with other space agencies; and finally adding "heavier infrastructure" to support long-term stays on the lunar surface, including the Italian Space Agency's Multi-purpose Habitats and the Canadian Space Agency's Lunar Utility Vehicle. NASA says it's aiming to start this plan off with crewed moon landings every six months following the Artemis V mission, which is currently planned for 2028.
Comet 41P pulls a reverse card
A study published this week in The Astronomical Journal describes what's said to be the first observation of a comet reversing its spin. Observations taken several months apart in 2017 show the comet 41P/Tuttle-Giacobini-Kresák starting to spin more slowly after making a close flyby of the sun, before picking up speed again by December of that year. Its spin period, measured using NASA’s Neil Gehrels Swift Observatory, was about 46-60 hours in May 2017, but later observations by the Hubble Space Telescope showed it was just 14 hours, according to NASA. The researchers say what likely happened is that the heat from the sun caused the comet's ice to sublimate, sending gases spewing off its sides.
“Jets of gas streaming off the surface can act like small thrusters,” author David Jewitt of the University of California at Los Angeles, said in a statement. “If those jets are unevenly distributed, they can dramatically change how a comet, especially a small one, rotates.” Jewitt compares it to pushing a merry-go-round. “If it’s turning in one direction, and then you push against that, you can slow it and reverse it.”
Comet 41P is thought to have come from the Kuiper Belt and passes through the inner solar system every 5.4 years. It's small, with a nucleus of just around .6 miles, and the researchers found it's become less active over recent years, indicating that there are changes taking place on the surface. While it's thought to have been in this orbit for about 1,500 years, it now appears to be rapidly evolving, and the rotational changes — which could cause structural instability if it continues — could mark the beginning of the end for it. “I expect this nucleus will very quickly self-destruct,” said Jewitt.
Saturn in a new light
A side-by-side-comparison of photos captured of Saturn from the Webb telescope and the Hubble telescope.
NASA/ESA/CSA
Stunning images of Saturn released this week by NASA, ESA and CSA provide a more detailed look at the many layers of the ringed planet's "busy" atmosphere. The images, which show storms, clouds at different depths, Saturn's "ribbon wave" jet stream and so much more were taken by the Hubble Space Telescope and the James Webb Space Telescope in 2024. Read more about it here.

The ESA, NASA and CSA have released new images of Saturn captured by the James Webb and Hubble space telescopes that offer an unprecedented view of the gas giant's atmosphere. Particularly, comparing shots captured with Hubble against an infrared view from Webb highlights details in the composition and movement of Saturn's outer layers.
The Hubble images were captured as part of the Outer Planet Atmosphere Legacy program in August 2024, while the Webb images were shot a few months later. "Both sense sunlight reflected from Saturn’s banded clouds and hazes," NASA says, "but where Hubble reveals subtle color variations across the planet, Webb’s infrared view senses clouds and chemicals at many different depths in the atmosphere, from the deep clouds to the tenuous upper atmosphere."
Hubble has historically been used to track storms on Saturn, and you can see bands of atmospheric clouds in the telescope's new photo. The infrared sensors on the Webb telescope are able to highlight even more detail, like the highly-reflective ice of Saturn's ring, which is practically white in the photo, and grey-green shading on the planet's poles. The different coloring in the Webb photo could be caused by a "a layer of high-altitude aerosols" scattering light across latitudes, or "charged molecules interacting with the planet’s magnetic field" and causing "auroral activity."
The visual information from both telescopes is valuable to scientists and should prove to be more valuable over time. "These 2024 observations, taken 14 weeks apart, show the planet moving from northern summer toward the 2025 equinox," NASA says. "As Saturn transitions into southern spring, and later southern summer in the 2030’s, Hubble and Webb will have progressively better views of that hemisphere."

Remember when Japan sent a spacecraft to an asteroid 180 million miles away to scoop some dirt off the surface? Six years on from its arrival to Earth, that sample has yielded some insights about what may have seeded life on our planet. Read on to learn more about the latest findings, and other science news we found interesting this week.
DNA ingredients on Ryugu
In 2020, a capsule from the Japanese space probe Hayabusa2 returned to Earth with samples collected from the surface of asteroid Ryugu, and scientists have spent the subsequent years analyzing those materials for clues about the conditions that existed in the early solar system. This week, researchers from Japan reported an exciting discovery: the Ryugu samples contain the five building blocks of DNA and RNA. The findings, coupled with those from other recent studies, could put us closer to understanding how the ingredients for life first made it to Earth billions of years ago.
The study, published in the journal Nature Astronomy, found the nucleobases adenine, guanine, cytosine, thymine and uracil — all of which were also found in samples gathered from a different asteroid, Bennu, last year, and before that in meteorites dubbed Murchison and Orgueil. This suggests these nucleobases were widespread in the early solar system, and supports the hypothesis that carbonaceous asteroids like Ryugu and Bennu transported them to Earth, the authors explain in the paper. Ammonia was discovered in the samples as well, which may play a role in how these nucleobases formed.
The discovery of these building blocks "does not mean that life existed on Ryugu," Toshiki Koga, the study's lead author from the Japan Agency for Marine-Earth Science and Technology, told AFP. "Instead, their presence indicates that primitive asteroids could produce and preserve molecules that are important for the chemistry related to the origin of life."
Bacteria collaborate to eat plastic waste
Researchers in Germany have identified a trio of bacteria that can digest a common plastic additive, but only when working together. The study published in the journal Frontiers in Microbiologyfound that a "consortium" of bacterial strains (two from species in the genus Pseudomonas and one from Microbacterium)was able to break down several phthalate esters (PAEs), which are often used to make plastic materials more flexible. These chemicals are increasingly finding their way into the environment as plastic pollution grows, and research suggests they can have harmful effects on human health and that of wildlife.
The team focused on microbes that could be found right at home in their own lab, taking a sample of biofilm that had formed on the polyurethane tubing of a bioreactor. This sample was then incubated in a growth medium containing the PAE diethyl phthalate (DEP) as the main source of carbon and energy. They eventually ended up with a stable culture of bacteria that could break down DEP, as long as the DEP concentration didn't exceed 888 milligrams per liter, according to a press release. The consortium could gobble up all the DEP in 24 hours at 30 degrees C. It was also able to grow on the PAEs dimethyl phthalate, dipropyl phthalate and dibutyl phthalate.
The researchers identified the bacteria in the consortium through DNA sequencing, but found that they were not individually able to tackle the PAEs, suggesting they break down the chemicals through a "cooperative process" known as cross-feeding. The consortium could make for another tool in the pollution-fighting toolbox, with potential to help break down PAEs in contaminated areas or speed up the degradation of plastics that contain PAEs by making them more brittle. "This approach may also be effective in treating industrial plastic waste streams," they note.
Hubble witnesses a breakup
Newly released images from the Hubble Space Telescope show the unexpected breakup of Comet C/2025 K1 (ATLAS) — Comet K1, for short — as it made its way out of the solar system back in November. A team of researchers that initially set out to observe a different comet ended up switching targets due to technical issues, only to catch Comet K1 right after it started crumbling. Hubble captured three 20-second images between November 8 and November 10 2025, the first of which the team estimates was about eight days after the fragmenting started. During the observation period, one of the comet's smaller pieces began to break up too. Talk about being in the right place at the right time.
"Never before has Hubble caught a fragmenting comet this close to when it actually fell apart," said John Noonan, a research professor in the Department of Physics at Auburn University, in a statement. "Most of the time, it’s a few weeks to a month later. And in this case, we were able to see it just days after." You can read more about the rare sighting here.

Blue Origin has revealed its plans for an orbital AI data center system in a new filing with the Federal Communications Commission. The company has asked the agency for permission to deploy 51,600 satellites, as reported by the Wall Street Journaland SpaceNews. Called Project Sunrise, the initiative aims to launch and operate a constellation of satellites that can deliver computing capacity for artificial intelligence uses.
Project Sunrise’s satellites will be placed in sun-synchronous orbits at altitudes between 311 and 1,118 miles. Each layer in the constellation will have between 300 to 1,000 satellites and will be approximately 3 to 6 miles apart. In its filing, Blue Origin said the constellation would complement terrestrial data centers.
The satellites will, of course, will be fitted with solar panels to be able to gather energy from the sun. Blue Origin explained that the orbital AI data center will lower the “marginal cost of compute capacity compared to terrestrial alternatives,” because the satellites will be powered by the sun, won’t need land and won’t need grid infrastructure. Project Sunrise will “enable US companies developing and using AI to flourish, accelerating breakthroughs in machine learning, autonomous systems and predictive analytics,” Blue Origin added.
By filing its request with the FCC, Blue Origin has officially joined SpaceX in the list of companies looking to build an AI data center in space. In January, SpaceX asked the FCC for permission to deploy 1 million satellites for its constellation. The company justified at the time that “orbital data centers are the most efficient way to meet the accelerating demand for AI computing power.”

NASA and ESA have released new images from the Hubble Space Telescope of a comet breaking up as it exits the solar system, captured as part of study recently published in the journal Icarus. The images are notable not only because they offer a more detailed view of the inside of a comet, which could offer new information about the early days of the universe, but also because they were taken by accident.
Photographing K1, or "Comet C/2025 K1" as it's officially known, wasn't the original intention of the study. "This comet [was] observed because our original comet was not viewable due to some new technical constraints after we won our proposal," John Noonan, a research professor in the Department of Physics at Auburn University in Alabama said. "We had to find a new target — and right when we observed it, it happened to break apart, which is the slimmest of slim chances."
The comet broke up over a period of days into "at least four pieces," each with a "fuzzy envelope of gas and dust" around them, with Hubble specifically capturing the disassembly from November 8 through November 10, 2025. K1 was interesting before it started to crumble because at "around 8 kilometers across" (about 5 miles), it's larger than the average comet, and having footage of it shattering will likely offer new insights into the physics of comets in general. Additionally, the lack of carbon in the gases released by the comet as it broke is apparently "chemically very strange," which suggests the composition of K1 could bear scientific fruit, too.
Hubble has tracked comets of different sizes and compositions for years. Studying them remains a focus because comets are frequently made of ice and rock from the primordial period when solar systems were first forming. The ESA hopes to dramatically expand our understanding of that period with its "Comet Interceptor" mission, which is supposed to launch in 2028 or 2029, and aims to use photos captured from multiple angles to create a 3D model of a comet.
