Now we know why Japan’s lunar lander wasn’t able to recharge its batteries after touching down on the moon last week: The spacecraft appears to have tumbled onto its side, with its solar cells facing away from the sun.

The good news is that the Smart Lander for Investigating Moon, or SLIM, achieved its primary mission of setting down within 100 meters (330 feet) of its target point — and that the mission’s two mini-probes, which were ejected during SLIM’s descent, are working as intended.

Scores of images were taken before and after landing. One of the pictures. captured by a camera on the ball-shaped LEV-2 mini-probe, shows the lander sitting at an odd angle with its thrusters facing upward and its solar cells facing westward.

To conserve battery power, mission managers at the Japan Aerospace Exploration Agency shut down SLIM after the probes transmitted the imagery they collected. But there’s still a chance that the sun’s shifting rays could provide enough power to allow for further operations in the week ahead.

Japan’s Moon Lander Touches Down, But Power Problem Mars Its Mission

Update for Jan. 21: The Japan Aerospace Exploration Agency shut down its moon lander to conserve battery power, but says the lander might be recharged and revived if sunlight hits the solar cells at the right angle.

Japan has become the fifth nation to land a functioning robot on the moon, but the mission could fall short of complete success due to a problem with the lander’s power-generating solar cells.

Why Serious Scientists Are Mesmerized by the Multiverse

The multiverse may be a cool (and convenient) concept for comic books and superhero movies, but why do scientists take it seriously?

In a new book titled “The Allure of the Multiverse,” physicist Paul Halpern traces why many theorists have come to believe that longstanding scientific puzzles can be solved only if they allow for the existence of other universes outside our own — even if they have no firm evidence for such realms.

It’s easy to confuse the hypotheses with the hype, but Halpern says there’s a huge difference between the multiverse that physicists propose and the mystical realm that’s portrayed in movies like “Doctor Strange in the Multiverse of Madness.”

“Some people accuse scientists of trying to delve into science fiction if they even mention the multiverse,” Halpern says in the latest episode of the Fiction Science podcast. “But the type of science that people are doing when they talk about the multiverse is real science. It’s far-reaching science, but it’s real science. Scientists are not saying, ‘Hey, maybe we can meet another Spider-Man and attack Kingpin that way.'”

Get a Reality Check on Plans to Build Cities in Space

Elon Musk and Jeff Bezos may harbor multibillion-dollar dreams of sending millions of people to live on Mars, on the moon and inside free-flying space habitats — but a newly published book provides a prudent piece of advice: Don’t go too boldly.

It’s advice that Kelly and Zach Weinersmith didn’t expect they’d be giving when they began to work on their book, titled “A City on Mars.” They thought they’d be writing a guide to the golden age of space settlement that Musk and Bezos were promising.

“We ended up doing a ton of research on space settlements from just every angle you can imagine,” Zach Weinersmith says in the latest episode of the Fiction Science podcast. “This was a four-year research project. And about two and a half years in, we went from being fairly optimistic about it as a desirable, near-term likely possibility [to] probably unlikely in the near term, and possibly undesirable in the near term. So it was quite a change. Slightly traumatic, I would say.”

‘Her Space, Her Time’ Reveals the Hidden Figures of Physics

Quick: Name a woman scientist.

Chances are the name you came up with is Marie Curie, the physicist and chemist who won two Nobel Prizes more than a century ago for the discoveries she and her husband Pierre made about radioactivity.

But who else? In a new book titled “Her Space, Her Time,” quantum physicist Shohini Ghose explains why women astronomers and physicists have been mostly invisible in the past — and profiles 20 researchers who lost out on what should have been Nobel-level fame.

“This issue around having low representation of women in physics is something that’s common all around the world,” Ghose says in the latest episode of the Fiction Science podcast. “And I’ve certainly faced it in my own experiences as a physicist growing up. I really didn’t know of any woman physicist apart from Marie Curie.”

What’s Next for NASA’s UFO Research? Outside Observers Weigh In

BOULDER, Colo. — NASA says it’s going to play a bigger role in studying what’s behind unidentified anomalous phenomena, the newfangled name for what we used to call UFOs. But exactly how should NASA step into that role? The astrophysicist who helped get the ball rolling last year as NASA’s associate administrator for science is suggesting a quick and easy way to get started.

Following Up on Report, NASA Takes On a Bigger Role in UFO Research

In response to a new report from an independent panel, NASA says it has appointed a director in charge of research into UFOs — now known as unidentified anomalous phenomena, or UAPs — and will work with other agencies to widen the net for collecting UAP data.

“This is the first time that NASA has taken concrete action to seriously look into UAP,” NASA Administrator Bill Nelson said today during a news briefing at NASA’s headquarters in Washington.

NASA initially kept the name of its UAP research director under wraps, but later in the day, the agency identified him as Mark McInerney, who has previously served as NASA’s liaison to the Department of Defense on the UAP issue.

Nelson downplayed the idea that aliens were behind any of the anomalous phenomena recorded to date, but he pledged to keep an open mind.

Pentagon Unveils New Website for Reporting (and Learning About) UFOs

The Pentagon has opened up a new portal on the internet for professionals to submit reports about UFOs — now officially known as unidentified anomalous phenomena, or UAPs — and for the rest of us to find out about the reports that have been released.

AARO.mil, the website for the All-domain Anomaly Resolution Office, is still a work in progress. For example, a promised online form for contacting the AARO is labeled as “Coming Soon.” But the version unveiled today offers eight videos showing UAPs, plus archives for congressional reports and briefings, press releases and links to other resources.

Virgin Galactic Flies Its First Privately Funded Space Tourists

Virgin Galactic sent its first privately funded adventurers — and its first space sweepstakes winners — past the 50-mile space boundary today.

The tourists on the suborbital space trip known as Galactic 02 included Keisha Schahaff, who won two tickets in an online contest organized by the Omaze charity sweepstakes platform and a nonprofit group called Space for Humanity in 2021. She and her daughter, Anastatia Mayers, became the first mother-and-daughter duo to share a spaceflight, and the first spacefliers from the Caribbean island nation of Antigua and Barbuda.

“I kind of feel like I was born in this life for this,” Schahaff, a wellness coach, told NBC’s “Today” show. Her daughter is a college student who aims to become an astrobiologist.

Jon Goodwin — an 80-year-old British adventurer who competed as a canoeist in the 1972 Olympics — also broke barriers on today’s Galactic 02 flight. In 2005, he was one of the first customers to reserve a spot with Virgin Galactic, back when the price was $200,000. Then, almost a decade ago, he was diagnosed with Parkinson’s disease. Today he became only the second person with Parkinson’s to take a space trip. (The first was NASA shuttle astronaut Rich Clifford.)

How Will We the Find First Signs of Alien Life — and When?

When will we find evidence for life beyond Earth? And where will that evidence be found? University of Arizona astronomer Chris Impey, the author of a book called “Worlds Without End,” is betting that the first evidence will come to light within the next decade or so.

But don’t expect to see little green men or pointy-eared Vulcans. And don’t expect to get radio signals from a far-off planetary system, as depicted in the 1992 movie “Contact.”

Instead, Impey expects that NASA’s James Webb Space Telescope — or one of the giant Earth-based telescopes that’s gearing up for observations — will detect the spectroscopic signature of biological activity in the atmosphere of a planet that’s light-years away from us.

“Spectroscopic data is not as appealing to the general public,” Impey admits in the latest episode of the Fiction Science podcast. “People like pictures, and so spectroscopy never gets its fair due in the general talk about astronomy or science, because it’s slightly more esoteric. But it is the tool of choice here.”
