A Nebula Straight From The Stars To Your Table

Space may truly be the final frontier, but maybe that frontier can be closer than you thought. Pictures of nebulae and planets bring the colorful sights of deep space right to your screen. You may even have models of some of the rockets used for those missions on a shelf. However, did you know that you could even have a model of those nebulae or planetary surfaces from [NASA]?

While we have covered some distributed models from [NASA] here before, the catalog has expanded far past what 2016 had in store. Additionally, the catalog has been sorted into a more user-friendly, filterable interface than a simple GitHub repository. Most models even have a description attached, giving some basic background information on what the Crab Nebula is, for example.

There could always be more; there don’t appear to be many models of the space shuttle or some other expected files, but what is there is incredible. Some non-3D model files can also be found from star maps to full planetary maps.

While this file repository is cool and all, it’s not all [NASA] does. When not sending rockets deep into space for cool pictures, [NASA] has to make sure the Moon doesn’t explode. Was that a possibility at some point? Of course it has been!

Artemis II Agenda Keeps Moon-Bound Crew Busy

With the launch of Artemis II from Cape Canaveral potentially just weeks away, NASA has been releasing a steady stream of information about the mission through their official site and social media channels to get the public excited about the agency’s long-awaited return to the Moon. While the slickly produced videos and artist renderings might get the most attention, even the most mundane details about a flight that will put humans on the far side of our nearest celestial neighbor for the first time since 1972 can be fascinating.

The Artemis II Moon Mission Daily Agenda is a perfect example. Released earlier this week via the NASA blog, the document seems to have been all but ignored by the mainstream media. But the day-by-day breakdown of the Artemis II mission contains several interesting entries about what the four crew members will be working on during the ten day flight.

Of course, the exact details of the agenda are subject to change once the mission is underway. Some tasks could run longer than anticipated, experiments may not go as planned, and there’s no way to predict technical issues that may arise.

Conversely, the crew could end up breezing through some of the planned activities, freeing up time in the schedule. There’s simply no way of telling until it’s actually happening.

With the understanding that it’s all somewhat tentative, a look through the plan as it stands right now can give us an idea of the sort of highlights we can expect as we follow this historic mission down here on Earth.

The Moon Is Safe, For Now: No Collision In 2032 After All

When Asteroid 2024 YR4 was first discovered, it created a bit of a kerfuffle when it was reported it had a couple-percent chance of hitting the Earth in 2032. At 60 meters (196 feet) across, this would have been in the “city killer” class that nobody really wants to see make landfall, so NASA and the ESA scrambled all assets to refine its trajectory in time to do something about it. Amongst those assets was the James Webb Space Telescope (JWST), which is now reporting it will miss both us and our moon.

Even with the JWST, asteroid 2024 YR4 only fills a few pixels.

We reported that JWST was being tapped for this task over a year ago, when the main concern was still if YR4 might hit Earth or not. An Earth impact was fairly quickly ruled out as the window narrowed to include only to Earth’s moon, and concern shifted to excitement. A city killer striking Earth is obviously bad news. The same thing happening to the Moon is a chance to do science — and 2032 would have been plenty of time to get assets in place to observe the impact.

Unfortunately for the impact-curious, JWST was able to narrow down the trajectory further — and we’ve now gone from up to a 4% chance of hitting Luna to a sure miss of 20,000 km or more.

As this game of cosmic billiards we call a solar system continues, it’s only a matter of time before Earth or her moon is struck by another object. Unless we can deflect it, that is — NASA and partnering agencies have been testing how to do that.

New Artemis Plan Returns To Apollo Playbook

In their recent announcement, NASA has made official what pretty much anyone following the Artemis lunar program could have told you years ago — humans won’t be landing on the Moon in 2028.

It was always an ambitious timeline, especially given the scope of the mission. It wouldn’t be enough to revisit the Moon in a spidery lander that could only hold two crew members and a few hundred kilograms of gear like in the 60s. This time, NASA wants to return to the lunar surface with hardware capable of setting up a sustained human presence. That means a new breed of lander that dwarfs anything the agency, or humanity for that matter, has ever tried to place on another celestial body.

Unsurprisingly, developing such vehicles and making sure they’re safe for crewed missions takes time and requires extensive testing. The simple fact is that the landers, being built by SpaceX and Blue Origin, won’t be ready in time to support the original Artemis III landing in 2028. Additionally, development of the new lunar extravehicular activity (EVA) suits by Axiom Space has fallen behind schedule. So even if one of the landers would have been ready to fly in 2028, the crew wouldn’t have the suits they need to actually leave the vehicle and work on the surface.

But while the Artemis spacecraft and EVA suits might be state of the art, NASA’s revised timeline for the program is taking a clear step back in time, hewing closer to the phased approach used during Apollo. This not only provides their various commercial partners with more time to work on their respective contributions, but critically, provides an opportunity to test them in space before committing to a crewed landing.

Practice Makes Perfect: The Wet Dress Rehearsal

If you’ve been even casually following NASA’s return to the Moon, you’re likely aware of the recent Wet Dress Rehearsal (WDR) for the Artemis II mission. You probably also heard that things didn’t go quite to plan: although the test was ultimately completed and the towering Space Launch System (SLS) rocket was fully loaded with propellant, a persistent liquid hydrogen leak and a few other incidental issues lead the space agency to delay further testing for at least a month while engineers make adjustments to the vehicle.

This constitutes a minor disappointment for fans of spaceflight, but when you’re strapping four astronauts onto more than five million pounds of propellants, there’s no such thing as being too cautious. In fact, there’s a school of thought that says if a WDR doesn’t shake loose some gremlins, you probably weren’t trying hard enough. Simulations and estimates only get you so far, the real thing is always more complex, and there’s bound to be something you didn’t account for ahead of time.

Hackaday Links: February 8, 2026

We start this week with a bit of a good news/bad news situation. On February 6th, the Relativistic Heavy Ion Collider (RHIC) was shut down after 25 years of operation. Located at Brookhaven National Laboratory in Upton, New York, the RHIC was the only operating particle collider in the United States, and along with the Large Hadron Collider (LHC), was one of only two heavy-ion colliders in existence.

So that’s the bad news. The good news is that the RHIC is going dark so that the Electron-Ion Collider (EIC) can take its place. Planned for activation in the mid-2030s, the EIC will occupy the same tunnel as the RHIC and reuse much of the same hardware. As the name implies, it will be used to collide electrons.

Switching gears (no pun intended) to the world of self-driving cars, Waymo’s chief safety officer, Dr. Mauricio Peña, made a surprising admission this week during a U.S. Senate hearing. When asked what his company’s vehicles do when they are presented with a situation that their on-board systems can’t resolve, Dr. Peña explained that they would contact a human “remote assistance operator.” He further clarified that these individuals, located both in the US and the Philippines, don’t literally drive the car remotely. Still, Senator Ed Markey of Massachusetts questioned not only the company’s transparency on the issue of remote assistance, but the idea that individuals overseas could be making decisions on how vehicles should operate on US roadways.

For many readers, more snow is the last thing they want to see right now…but what if it comes in the form of an online simulator in the style of an old DOS game? Created by [Potch], it works like one of those “falling sand” simulators, with sliders that let you control various elements of the wintry action. For more a immersive experience, open the window and let some cold air in while you play.

If those old school graphics have you yearning for a simpler time, then you’ll love Places to Telnet, a page on the very slick CRT-themed telnet.org that lists servers you can connect to. The list is made up primarily of games, but there’s also systems you can call up to do things like show the weather or browse Wikipedia. They even take submissions, so if you know any interesting destinations that aren’t on the list, make sure to share with the class.

Our ability to make and use tools is one of the things that separates us from the rest of the animal kingdom, and is an ability not often seen outside of primates. But a recent paper in Current Biology describes how one cow, Veronika, has been observed using a long-handled brush to scratch herself. Apparently the clever heifer will even flip the brush around and use the handle side when she wants to really dig in there. The paper says the findings “invite a reassessment of livestock cognition”, and points out that little serious research has been done on bovine intelligence in the 10,000 or so years since humans first domesticated them. We’re just happy this paper came out when it did — that way it will be a distant memory by the time we fire up the grill in the summer.
