NASA Announces Artemis III Crew And Ambitious Goals

June 10, 2026 by 40 Comments

When the Artemis lunar program was first conceived, the third mission would have seen astronauts step foot on the Moon for the first time since Apollo 17 in 1972. But as hard as getting into space is, a sojourn to our nearest celestial neighbor is even more mindbogglingly complex, and so earlier this year it was announced that actually landing on the Moon would be pushed out to the fourth mission.

In turn Artemis III would take a page out of the Apollo 9 playbook and test out rendezvous and docking procedures with commercial landers while operating in the relative safety of low Earth orbit. Moving the target date for the landing a few years down the road gave all involved parties a little more breathing room, but it also provided a valuable opportunity to gain insight into the performance of the vehicles and systems ahead of the critical moment. In the original timeline, the first time Orion would attempt to dock with the lander would have been just before descending to the lunar surface — leaving precious little time to troubleshoot should anything go wrong.

Yesterday NASA held a press conference to update the public on their progress towards the planned 2027 launch of Artemis III, which included the long-awaited announcement of the crew that will kick the tires on the next-generation lunar landers being developed by SpaceX and Blue Origin

Questions Remain About Tense Moment Aboard ISS

June 9, 2026 by 22 Comments

Even if you’re not normally interested in what’s happening in low Earth orbit, you probably heard that last week NASA ordered its personnel aboard the International Space Station to button themselves up in the docked Dragon spacecraft and await further instructions should they need to make a hasty departure. Known as Safe Haven, this emergency procedure is performed whenever there’s an elevated risk of damage to the Station.

NASA has provided an update on what happened, but it arguably leaves more questions than answers. Usually, crews go to their Safe Haven because some bit of space junk has wandered to close to the orbiting complex, but this time it was because Russian cosmonauts Sergey Kud-Sverchkov and Sergei Mikayev were getting ready to start cutting into the walls of the PrK transfer tunnel in an effort to address its persistent air leak.

After about an hour and a half, the Russians called off the effort and NASA gave their people the OK to leave the Dragon and return to their normal duties. NASA Press Secretary Bethany Stevens later posted on social media that the space agency would “look forward to working with Roscosmos on a collaborative approach to address the leaks” in the future. There’s currently no word on what a future repair attempt may entail, or when it would be attempted.

This is one of those things were we might not hear the full story for some time, but it sure does sound like not only did the Russians want to do something that NASA didn’t think was safe, but that the whole thing was sprung on them at the last moment. To give you an idea of how serious Mission Control was taking the situation, they decided to cram five people into a Dragon capsule that only has four seats — it certainly would have made for one wild ride down to Earth if they were given the order to evacuate.

What do you want to bet there were some frantic international calls taking place while the astronauts were hiding out in their designated lifeboat?

How Did Apollo Separate?

May 13, 2026 by 23 Comments

If you’ve watched a Saturn V launch, you’ve probably seen how a large rocket will often jettison a stage on the way up. There are several reasons for this — there is no reason to haul an empty fuel container, for example. However, you can probably imagine how the separation works. You release something — probably explosive bolts — and gravity pulls the old stage away from you as you climb on the next stage’s engines. But what about on the way back? The command module drops the service module before reentry. [Apollo11Space] has a video explaining just how complicated that was to pull off. You can watch it below.

The main problem? The service module has almost everything you need: oxygen, a big engine, fuel, and electrical generation capability. If you’ve ever seen a real command module, they are tiny. Somehow, you need to get the command module prepared to be on its own for the amount of time it takes to land, and get the service module safely away.

From Lunar Dust To Breathable Air

April 13, 2026 by 27 Comments

Moon missions are hot again for the first bit since the space race. While the previous period had us land on the big lunar rock, the missions of tomorrow have us living on it. The initial problem of landing in one piece has been solved, but there are many more puzzles to solve. One major issue of living in the vacuum of space is the lack of breathable air, because, ya know, it’s space.

This brings us to today, where [Blue Origin] has announced a prototype method of turning Moon dust into the valuable gas we call oxygen. [Blue Origin] hasn’t posted much about the actual process behind this feat, terming the system “Air Pioneer”. What we do know is that it requires melting the regolith and then passing current through to release the O2 molecules from their rocky prison.

While some publications on this matter have been calling this a first in its entirety, this isn’t entirely true. NASA has worked on this technology for the past couple of years, called “Gaseous Lunar Oxygen from Regolith Electrolysis”, or (GaLORE). What [Blue Origin] has done, however, is complete the task under a for-profit motive. Perhaps this can introduce the drive needed to accelerate the development of the tech? (If anyone knows any more detail about the Blue Origins system, please let us know.)

Private space is certainly an exciting and quickly moving space in nearly all regards. It’s important to see how far we have come from the initial moon missions. If you want to check out some of the wackier lessons from that era, be sure to read up on the fight for moon cockroaches!

In Space (Probably) Everyone Can Hear You.. Well, You Know

April 6, 2026 by 28 Comments

The news is full of reports from the moon-bound Integrity, otherwise known as Artemis II. Mostly, the news is good, but there has been one “Houston, we have a problem…” moment. The space toilet, otherwise known as the Universal Waste Management System or UWMS is making a burning smell while in use. While we would love to be astronauts, we really don’t want to go ten days without using the can, and it made us wonder how, exactly, the astronauts answered the call of nature.

The Old Days

Back in the Apollo-era, going to the bathroom was a messy business. The capsule wasn’t that big, and there were no women on board. So you simply strapped an adhesive-rimmed bag or tube to yourself and answered nature’s call with your two closest coworkers right there.

To add insult to injury, the “#2 bags” needed some packet mixed in to keep it from going bad in the bag before it could return to Earth for — no kidding — scientific study.

The system was far from perfect. Apollo 8 and Apollo 10 both had to do some housekeeping due to leaky bags.

Astronaut Ken Mattingly reportedly said, “Man, one of the feats of my existence the other day was, in 42 minutes, I strapped on a bag, went out of both ends, and ate lunch…. I used to want to be the first man to Mars. This has convinced me that, if we got to go on Apollo, I ain’t interested.”

Still, it was better than the first Mercury launch, where Alan Shepard famously relieved himself in his spacesuit while sitting on the pad for over eight hours. Later missions used hoses.

Things got slightly better with Skylab, where there was more room. The Shuttle also had a toilet. You got a curtain for privacy, but you couldn’t go #1 and #2 at the same time. Also, apparently, the contraptions were not easily workable for females.

A Nebula Straight From The Stars To Your Table

March 31, 2026 by 3 Comments

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!
