Pilot Victor Glover flew the vehicle through a variety of maneuvers primarily using Orion's 24 reaction control thrusters, demonstrating the vehicle's handling capabilities.

The new work was less notable for showing that we had found these bases in Ryugu than for solving a previous mystery: earlier studies had failed to detect them there, despite their presence in many other asteroid samples.

In the silent vacuum of space, five autonomous robots churn through the lunar surface, digging up a loose layer of rock and dust and leaving rows of uniform tracks in their wake. Stopping only to recharge at a central solar power station, the car-sized machines process the lunar dirt internally to extract a type of helium so rare on Earth that a palm-sized container is estimated to be worth millions.

Only 24 people have seen the far side of the Moon with their own eyes in the entire history of humanity. All of them were men, Americans, and white: the crew members of the nine Apollo missions that traveled to the Moon between 1968 and 1972.

The momentum enhancement factor for DART's impact was about two, meaning that the debris loss doubled the punch created by the spacecraft alone. The new study shows the impact ejected so much material from the binary system that it also changed the binary's orbital period around the Sun by 0.15 seconds.

The Starship rocket system splits in two after takeoff. The upper spacecraft would head to Earth orbit to serve as that depot, ready to carry nothing but fuel. The towering Super Heavy rocket booster, meanwhile, would return to the launch site so it can be reused.

We found that life is more likely to survive an asteroid impact, so it's definitely still a real possibility that life on Earth could have come from Mars. Maybe we're Martians! The idea that life could have spread through the solar system or even the universe on rocks is known as the lithopanspermia hypothesis.

Our new study suggests that the Apollo samples are biased to extremely rare events that lasted a few thousand years - but up to now, these have been interpreted as representing 0.5 billion years of lunar history. It now seems that a sampling bias prevented us from realizing how short and rare these strong magnetism events were.

Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging. At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

It did so with the blessing of engineers at NASA's Jet Propulsion Laboratory (JPL), who decided to delegate the meticulous work of route planning to Anthropic's AI model. This involves consulting orbital and surface imagery of Mars in order to set a series of waypoints to guide the rover's movements. Once plotted, this data gets transmitted about 140 million miles or 225 million kilometers - the average distance from Earth to Mars - where it's received by Perseverance as a navigational plan.

NASA is quietly ending financial support for independent planetary science advisory groups, according to a letter posted to the agency's website on January 16. The affected groups have historically offered feedback to the space agency on science efforts ranging from the exploration of Mars and ocean worlds to the storage of extraterrestrial samples, and more. According to the letter, signed by Louise Prockter, director of NASA's Planetary Science Division, funding to support these Analysis and Assessment Groups will end toward the end of April 2026.

Since 2021, NASA's Perseverance rover has achieved a number of historic milestones, including sending back the first audio recordings from Mars. Now, nearly five years after landing on the Red Planet, it just achieved another feat. This past December, Perseverance successfully completed a route through a section of the Jezero crater plotted by Anthropic's Claude chatbot, marking the first time NASA has used a large language model to pilot the car-sized robot.

The moon is going nuclear. On Tuesday NASA and the U.S. Department of Energy announced a commitment to build a fission reactor on the lunar surface. NASA has been exploring nuclear power for the moon for years, but the endeavor got a boost late last year in an order from President Donald Trump to build one to ensure American space superiority. The reactor will be capable of operating for years without the need to refuel, according to NASA.

A global research team has analyzed the prospects for biomineralization on Mars, a process in which bacteria, fungi, and microalgae can create minerals as part of their metabolism, offering a byproduct that could be useful to prospective Martian explorers by providing the raw materials needed to produce aggregates such as concrete. With an extremely thin and mostly carbon dioxide atmosphere, air pressure less than 1 percent of Earth's,

I think the first thing to remember is: We are right at the beginning of this adventure. There's so much excitement that every little signal - every "wiggle" in a spectrum - gets people saying, "Oh! That might be life!" And then, on the other side, other people respond with, "I don't see enough wiggles, so there's probably not even an atmosphere. Dead planet. Move on." Both reactions are too fast.

The population of super-Earths and sub-Neptunes, and the origin of the radius valley that separates these two classes of planets, is best explained by cores that are made of an Earth-like composition without a substantial amount of accreted ice8,9,10,11. For sub-Neptunes, the hydrogen-rich envelope overlies the rocky core for billions of years, whereas for super-Earths, the envelope may be retained for about 100 Myr (refs. ).
