Another day, another crop of newly minted minimal astronauts, as Blue Origin’s New Shepard made a successful suborbital flight this week. Everything seemed to go according to plan, at least until right at the end, when an “unexpected foliage contingency” made astronaut egress a little more complicated than usual. The New Shepard capsule had the bad taste to touch down with a bit of West Texas shrubbery directly aligned with the hatch, making it difficult to find good footing for the platform used by the astronauts for the obligatory “smile and wave” upon exiting. The Blue Origin ground crew, clad in their stylish black and blue outfits that must be murderously impractical in the West Texas desert, stamped down the brush to place the stairway, but had a lot of trouble getting it to sit straight. Even with the impromptu landscaping, the terrain made it tough to get good footing without adding random bits of stuff to prop up one leg, an important task considering that one of the new astronauts was a 90-year-old man. It seems pretty short-sighted not to have adjustable legs on the stairway, but there it is.
By the end of the decade, NASA’s Artemis program hopes to have placed boots back on the Moon for the first time since 1972. But not for the quick sightseeing jaunts of the Apollo era — the space agency wants to send regular missions made up of international crews down to the lunar surface, where they’ll eventually have permanent living and working facilities.
The goal is to turn the Moon into a scientific outpost, and that requires a payload delivery infrastructure far more capable than the Apollo Lunar Module (LM). NASA asked their commercial partners to design crewed lunar landers that could deliver tens of tons of to the lunar surface, with SpaceX and Blue Origin ultimately being awarded contracts to build and demonstrate their vehicles over the next several years.
Starship and Blue Moon, note scale of astronauts
At a glance, the two landers would appear to have very little in common. The SpaceX Starship is a sleek, towering rocket that looks like something from a 1950s science fiction film; while the Blue Moon lander utilizes a more conventional design that’s reminiscent of a modernized Apollo LM. The dichotomy is intentional. NASA believes there’s a built-in level of operational redundancy provided by the companies using two very different approaches to solve the same goal. Should one of the landers be delayed or found deficient in some way, the other company’s parallel work would be unaffected.
But despite their differences, both landers do utilize one common technology, and it’s a pretty big one. So big, in fact, that neither lander will be able to touch the Moon until it can be perfected. What’s worse is that, to date, it’s an almost entirely unproven technology that’s never been demonstrated at anywhere near the scale required.
Even if you’re just making a brief hop over the Kármán line to gain a few minutes of weightlessness, getting to space is hard. Just in case any of their engineers were getting complacent, Blue Origin just got a big reminder of that fact this afternoon with the destruction of their New Shepard 3 (NS3) rocket during a suborbital research flight.
But while the rocket itself was lost, the New Shepard’s automated abort systems were able to push the capsule H. G. Wells away from the fireball, saving the dozens of scientific experiments which had been loaded onto the un-crewed vehicle. While there’s been no public word yet on the condition of these experiments, it’s reasonable to assume that at least some portion of them can be re-flown in the future — a fact that will likely come as a great relief to the researchers who designed them. It will be interesting to see who picks up the tab for the do-over flight; while launch insurance is a must-have for billion dollar satellites, it seems unlikely these small suborbital experiments would have been covered under a similar policy.
A spurt of flame can be seen in the otherwise invisible exhaust moments before engine failure.
We’re also still in the dark about what caused the in-flight breakup of NS3, other than the fact that the engine was clearly sputtering in the seconds before it blew apart. This could be a sign that the engine’s nominal fuel-to-oxidizer ratio was faltering, or perhaps even indicative of foreign debris becoming dislodged and burning in the combustion chamber. But really, without official word from Blue Origin, it’s impossible to say what happened.
This is especially true when you consider that we’re talking about a vehicle that’s pushing the envelope to begin with. Remember, the New Shepard is a reusable booster, and NS3 is specifically a veteran of eight flights — with all but one of them taking the booster above the 100 kilometer altitude, which is generally accepted to be the boundary of space.
For those worried that celebrities and assorted millionaires will no longer have access to space, fear not. Blue Origin’s crewed flights have flown exclusively on the newer NS4 and its associated capsule First Step. This does however mean that Blue Origin no longer has a spare booster on which to fly commercial payloads, potentially putting into jeopardy any semblance of scientific value the program may have had.
By any metric you care to use, this is a very exciting time for America’s space program. NASA is refocusing their efforts towards the Moon and beyond, SpaceX is launching routine crew and cargo flights to the International Space Station with reusable rockets, and if you’ve got deep enough pockets, there are now multiple companies offering suborbital pleasure trips requiring little more than a few hours worth of training. It’s taken longer than many people had hoped, but it seems we’re finally making the confident strides necessary to truly utilize space’s vast resources.
But things are just getting started. A new generation of massive reusable rockets are currently being developed, which promise to make access to space cheaper and faster than ever before. We’ve seen quite a bit of SpaceX’s Starship, thanks in no small part to the dramatic test flights that the media-savvy company has been regularly live streaming to YouTube. But Blue Origin, founded by Amazon’s Jeff Bezos, has been far more secretive about their New Glenn. That is, until now.
GS1 under construction in Florida.
On November 8th, Blue Origin rolled out their GS1 simulator for the New Glenn’s first stage. This stand-in for the real rocket will never fly, but it’s designed to perfectly recreate the dimensions, center of gravity, and mass, of the real thing. Ground teams will use the GS1 to practice safely transporting the booster, which is approximately half the length of the Saturn V, from their production facility to Launch Complex 36 (LC-36) at Cape Canaveral. It will also be used to test the fit and function of various pieces of ground support equipment, and eventually, the second stage stacking procedure.
For the uninitiated, it might seem like this is a lot of fuss over what’s ultimately just a hollow metal tube. But the introduction of a test article such as this has traditionally been a major milestone during the design and construction of rockets and spacecraft, dating back to the “boilerplate” test capsules used during the Mercury, Gemini, and Apollo programs; a sure sign that what was just an idea is now becoming a reality.
We have to admit, it was hard not to be insufferably smug this week when Facebook temporarily went dark around the globe. Sick of being stalked by crazy aunts and cousins, I opted out of that little slice of cyber-hell at least a decade ago, so Monday’s outage was no skin off my teeth. But it was nice to see that the world didn’t stop turning. More interesting are the technical postmortems on the outage, particularly this great analysis by the good folks at the University of Nottingham. Dr. Steve Bagley does a great job explaining how Facebook likely pushed a configuration change to the Border Gateway Protocol (BGP) that propagated through the Internet and eventually erased all routes to Facebook’s servers from the DNS system. He also uses a graphical map of routes to show peer-to-peer connections to Facebook dropping one at a time, until their machines were totally isolated. He also offers speculation on why Facebook engineers were denied internal access, sometimes physically, to their own systems.
It may be a couple of decades overdue, but the US Federal Communications Commission finally decided to allow FM voice transmissions on Citizen’s Band radios. It seems odd to be messing around with a radio service whose heyday was in the 1970s, but Cobra, the CB radio manufacturer, petitioned for a rule change to allow frequency modulation in addition to the standard amplitude modulation that’s currently mandatory. It’s hard to say how this will improve the CB user experience, which last time we checked is a horrifying mix of shouting, screaming voices often with a weird echo effect, all put through powerful — and illegal — linear amps that distort the signal beyond intelligibility. We can’t see how a little less static is going to improve that.
Can you steal a car with a Game Boy? Probably not, but car thieves in the UK are using some sort of device hidden in a Game Boy case to boost expensive cars. A group of three men in Yorkshire used the device, which supposedly cost £20,000 ($27,000), to wirelessly defeat the security systems on cars in seconds. They stole cars for garages and driveways to the tune of £180,000 — not a bad return on their investment. It’s not clear how the device works, but we’d love to find out — for science, of course.
There have been tons of stories lately about all the things AI is good for, and all the magical promises it will deliver on given enough time. And it may well, but we’re still early enough in the AI hype curve to take everything we see with a grain of salt. However, one area that bears watching is the ability of AI to help fill in the gaps left when an artist is struck down before completing their work. And perhaps no artist left so much on the table as Ludwig von Beethoven, with his famous unfinished 10th Symphony. When the German composer died, he had left only a few notes on what he wanted to do with the four-movement symphony. But those notes, along with a rich body of other works and deep knowledge of the composer’s creative process, have allowed a team of musicologists and AI experts to complete the 10th Symphony. The article contains a lot of technical detail, both on the musical and the informatics sides. How will it sound? Here’s a preview:
And finally, Captain Kirk is finally getting to space. William Shatner, who played captain — and later admiral — James Tiberius Kirk from the 1960s to the 1990s, will head to space aboard Blue Origin’s New Shepard rocket on Tuesday. At 90 years old, Shatner will edge out Wally Funk, who recently set the record after her Blue Origin flight at the age of 82. It’s interesting that Shatner agreed to go, since he is said to have previously refused the offer of a ride upstairs with Virgin Galactic. Whatever the reason for the change of heart, here’s hoping the flight goes well.
The Atlas family of rockets have been a mainstay of America’s space program since the dawn of the Space Age, when unused SM-65 Atlas intercontinental ballistic missiles (ICBMs) were refurbished and assigned more peaceful pursuits. Rather than lobbing thermonuclear warheads towards the Soviets, these former weapons of war carried the first American astronauts into orbit, helped build the satellite constellations that our modern way of life depends on, and expanded our knowledge of the solar system and beyond.

Naturally, the Atlas V that’s flying today looks nothing like the squat stainless steel rocket that carried John Glenn to orbit in 1962. Aerospace technology has evolved by leaps and bounds over the last 60 years, but by carrying over the lessons learned from each generation, the modern Atlas has become one of the most reliable orbital boosters ever flown. Since its introduction in 2002, the Atlas V has maintained an impeccable 100% success rate over 85 missions.
But as they say, all good things must come to an end. After more than 600 launches, United Launch Alliance (ULA) has announced that the final mission to fly on an Atlas has been booked. Between now and the end of the decade, ULA will fly 28 more missions on this legendary booster. By the time the last one leaves the pad the company plans to have fully transitioned to their new Vulcan booster, with the first flights of this next-generation vehicle currently scheduled for 2022.
Amateur radio operators have a saying: When all else fails, there’s ham radio. And that’s true, at least to an extent — knock out the power, tear down the phone lines, and burn up all the satellites in orbit, and there will still be hams talking about politics on 40 meters. The point is, as long as the laws of physics don’t change, hams will figure out a way to send and receive messages. In honor of that fact, the police in the city of Pune in Maharashtra, India, make it a point to exchange messages with their headquarter using Morse code once a week. The idea is to maintain a backup system, in case they can’t get a message through any other way. It’s a good idea, especially since they rotate all their radio operators through the Sunday morning ritual. We can’t imagine that most emergency services dispatchers would be thrilled about learning Morse, though.
Just because you’re a billionaire with a space company doesn’t mean you’re an astronaut. At least that’s the view of the US Federal Aviation Administration, which issued guidelines pretty much while Jeff Bezos and his merry band of cohorts were floating about above the 100-km high Kármán line in a Blue Origin “New Shepard” rocket. The FAA guidelines make it clear that those making the trip need to have actually done something to qualify as an astronaut, by “demonstrated activities during flight that were essential to public safety, or contributed to human space flight safety.” That’s good news to the “Old Shepard”, who clearly was in control of “Freedom 7” during the Mercury program. But the Bezos brothers, teenager Oliver Daemen, and Wally Funk, one of the “Mercury 13” group of women who trained to be NASA astronauts but never got to fly, were really just along for the ride, as the entire flight was automated. It doesn’t take away from the fact that they’ve been to space and you haven’t, of course, but they can’t officially call themselves astronauts. This goes to show that even billionaires can just be ballast too.
Good news, everyone — if you had anything that was being transported aboard the Ever Given, your stuff is almost there. The Suez Canal-occluding container ship finally made it to its original destination in Rotterdam, approximately four months later than originally predicted. After plugging up the vital waterway for six days last March, the ship along with her cargo and her crew were detained in Egypt’s Great Bitter Lake, perhaps the coolest sounding body of water in the world next to the Dead Sea. Legal squabbling ensued at that point, all the while rendering whatever was in the 20,000-odd containers aboard the ship pretty much pointless. We’d imagine that even with continuous power, whatever was in the refrigerated containers must be pretty nasty by now, so there’s probably a lot of logistics and clean-up left to sort out.
I have to admit that I have a weird love of explosive bolts. I don’t know what it is, but the idea of fasteners engineered to fail in a predictable way under the influence of pyrotechnic charges just tickles something in me. I mean, I even wrote a whole article on the subject once. So when I came across this video explaining how the Space Shuttles were held to the launch pad, I really had to watch it. Surprisingly, the most interesting part of this story was not the explosive aspect, but the engineering problem of supporting the massive vehicle on the launch pad. For as graceful as the Shuttles seemed once they got into orbit, they really were ungainly beasts, especially strapped to the external fuel tank and booster. The scale of the eight frangible nuts used to secure the boosters to the pad is just jaw-dropping. We also liked the idea that NASA decided to catch the debris from the explosions in a container filled with sand.
