Virgin Galactic Cautiously Returns To Flight

May 4, 2023 by Tom Nardi 32 Comments

After Richard Branson delivered some inspiring words from his seat aboard SpaceShipTwo Unity, he unbuckled himself and started to float around the vehicle’s cabin along with three other Virgin Galactic employees. Reaching an apogee of 86 kilometers (53 miles), the passengers enjoyed four minutes of weightlessness during the July 2021 flight that was live-streamed over the Internet to an audience of millions. After years of delays, SpaceShipTwo had finally demonstrated it was capable of taking paying customers to the edge of space. As far as victories go — it was pretty impressive.

Yet despite the spectacle, weeks and months went by without an announcement about when commercial flights of the world’s first “spaceline” would finally begin. Now, nearly two years after Branson’s flight, Unity has flown again. Except instead of carrying the first group of customers, it performed the sort of un-powered test flight that Virgin Galactic hasn’t performed since 2017. Clearly, something didn’t go to plan back then.

The company is being as tight-lipped as ever, saying only that this test flight was necessary to “evaluate the performance of the spaceship…following the modification period.” The exact nature of these modifications is unclear, but for some hints, we could look at the New Yorker article from September 2021. It alleged that, unwilling to derail Branson’s highly publicized flight, Unity’s pilots decided not to abort their ascent despite several warning lights in the cockpit alerting them that the vehicle’s trajectory was deviating from the norm. Virgin Galactic later denied their characterization of the event, but the fact remains that Unity did leave its designated airspace during the flight, and that the Federal Aviation Administration grounded the spacecraft until an investigation into the mishap could be completed.

Hackaday Links: August 15, 2021

Unless you’re in the market for a new car, household appliance, or game console, or if you’re involved in the manufacture of these things, chances are pretty good that the global semiconductor shortage hasn’t directly impacted you yet. But we hobbyists might be due for a comeuppance as the chip shortage starts to impact our corner of the market. We suppose it’s natural that supplies of the chips needed to build Arduinos and Raspberry Pis would start to dry up, as semiconductor manufacturers realign their resources to service their most lucrative markets. Still, it was all sort of abstract until now, but seeing dire quotes from the likes of Adafruit, Pololu, and Sparkfun about the long lead times they’re being quoted — some chips won’t be seen until 2023! — is disheartening. As are the reports of price gouging and even hoarding; when a $10 part can suddenly command $350, you know something has gone seriously wrong.

But have no fear — we’re certain the global chip shortage will have no impact on the planned 2027 opening of the world’s first space hotel. Voyager Station — once dubbed Von Braun Station but renamed for some reason — looks for all the world like Space Station V in “2001: A Space Odyssey”, or at least half of it. The thing is enormous — witness the Starship docked in the center hub, as well as the several dozen shuttle-like craft — escape pods, perhaps? — attached to the outer rim. The renders are imaginative, to say the least — the station looks very sleek, completely unfettered by such banalities as, say, solar panels. We get that a private outfit needs to attract deep-pocketed investors, and that one doesn’t do that by focusing on the technical details when they can sell a “premium experience”. But really, if you’re going to space, do you want basically the same look and feel as a premium hotel on Earth, just with a better view? Or would you rather feel like you’ve actually traveled to space?

Speaking of space, did you ever wonder what the first programmable calculator in space was? Neither did we, but that doesn’t mean we didn’t find this detailed story about the HP-65 that was sent up on the Apollo-Soyuz Test Project in 1975 pretty fascinating. The ASTP was the last hurrah of Apollo, and an often underappreciated engineering challenge. Linking up the two spacecraft safely was not trivial, and a fair number of burn calculations had to be made in orbit to achieve rendezvous and docking, as well as to maintain orbit. The HP-65, a programmable calculator that went for about $750 at the time (for the non-space-rated version, of course) had several programs loaded onto its removable magnetic cards, and the Apollo crew used it to verify the results calculated by the Apollo Guidance Computer (AGC).

Facebook, a company that exists by providing people with a product they don’t need but now somehow can’t live without, is now dipping a toe into weird, weird waters: reverse-passthrough virtual reality. The idea, we take it, is that as users more widely adopt VR and integrate it into their daily lives, the VR headsets everyone will be wearing will make face-to-face contact more difficult. So what better way to solve that problem than by projecting a live image of the VR user’s eyes onto a screen outside the VR rig, for any and all to see? Pure genius, and not the least bit creepy. They’ve perhaps got a bit of work to go before achieving their goal of “seamless social connection between real and virtual worlds”.

And speaking of eyes, it’s good to know that developers are still hard at work keeping the most vital applications running at peak efficiency on today’s hardware. Yes, the venerable XEyes, a program for the X Window System on Unix-like operating systems that draws a pair of googly eyes on the screen to follow your mouse movements, has finally moved to version 1.2.0. It’s been 11 years since the 1.1.0 upgrade, so it was a long time coming. If you haven’t had the chance to play with XEyes, fear not — just about any Linux machine should be able to show you what you’ve been missing. Or, you know, you could even run it on a camera as the video below the break shows.

This Group Of Women Tried To Break Into Astronaut Program In 1960s; One Just Made It

July 20, 2021 by Tom Nardi 33 Comments

When Mary Wallace “Wally” Funk reached the boundary of space aboard the first crewed flight of Blue Origin’s New Shepard capsule earlier today, it marked the end of a journey she started 60 years ago. In 1961 she became the youngest member of what would later become known as the “Mercury 13”, a group of accomplished female aviators that volunteered to be put through the same physical and mental qualification tests that NASA’s Mercury astronauts went through. But the promising experiment was cut short by the space agency’s rigid requirements for potential astronauts, and what John Glenn referred to in his testimony to the Committee on Science and Astronautics as the “social order” of America at the time.

Virgin Galactic’s Long Road To Commercial Spaceflight

June 1, 2021 by Tom Nardi 24 Comments

To hear founder Richard Branson tell it, the first operational flight of Virgin Galactic’s SpaceShipTwo has been 18 months out since at least 2008. But a series of delays, technical glitches, and several tragic accidents have continually pushed the date back to the point that many have wondered if it will ever happen at all. The company’s glacial pace has only been made more obvious when compared with their rivals in the commercial spaceflight field such as SpaceX and Blue Origin, which have made incredible leaps in bounds in the last decade.

But now, at long last, it seems like Branson’s suborbital spaceplane might finally start generating some income for the fledgling company. Their recent successful test flight, while technically the company’s third to reach space, represents an important milestone on the road to commercial service. Not only did it prove that changes made to Virgin Space Ship (VSS) Unity in response to issues identified during last year’s aborted flight were successful, but it was the first full duration mission to fly from Spaceport America, the company’s new operational base in New Mexico.

The data collected from this flight, which took pilots Frederick “CJ” Sturckow and Dave Mackay to an altitude of 89.23 kilometers (55.45 miles), will be thoroughly reviewed by the Federal Aviation Administration as part of the process to get the vehicle licensed for commercial service. The next flight will have four Virgin Galactic employees join the pilots, to test the craft’s performance when loaded with passengers. Finally, Branson himself will ride to the edge of space on Unity’s final test flight as a public demonstration of his faith in the vehicle.

If all goes according to plan, the whole process should be wrapped up before the end of the year. At that point, between the government contracts Virgin Galactic has secured for testing equipment and training astronauts in a weightless environment, and the backlog of more than 600 paying passengers, the company should be bringing in millions of dollars in revenue with each flight.

We’ve seen some interesting pitches in personal ads before, but this one takes the cake. Japanese billionaire Yusaku Maezawa is looking for a date to go along with him on his paid trip to the Moon, with the hope of finding a life partner. Maezawa is slated to be SpaceX’s first commercial lunar flyby customer, and will make the trip no earlier than 2023. That should give him plenty of time to go through the 20,000 applications he received from single women 20 and older with bright personalities and positive attitudes. And he should have plenty of time to make an awesome mixtape for the ride.

Imagine snooping through your kid’s garbage can only to find a used syringe lying in there. Most of us would likely be able to tell that the syringe once contained thermal compound or solder paste and be suitably proud of the little chip off the block, but apparently Cooler Master has fielded enough calls from panicked normie parents that they decided to change the design of their applicators. Given the design of the new applicator we doubt that’s really the reason, but it’s a good marketing story, and we can totally see how someone could mistake the old applicator for something illicit.

It looks as though SpaceX could be getting itself into legal trouble with its Starlink launches. Or more correctly, the FCC might, having apparently violated the National Environmental Policy Act, a Nixon-era law that requires government agencies to consider the environmental impact of any projects they approve. The Federal Communications Commission has been using a loophole in the law to claim a “categorical exemption” from these reviews when approving communications projects, particularly space-based projects. It’s not clear whether space is legally considered part of the environment, so the lawyers are hashing that out. If the FCC gets sued and loses, it’s not clear what happens to the existing Starlink satellites or future launches. Stay tuned for details.

Don’t forget that the Open Hardware Summit is coming soon. The 2020 meeting is the 10th anniversary of the confab, to be held on March 13 in New York. Hackaday is, of course, a proud sponsor of the conference, and our own Sophi Kravtiz will be the keynote speaker! Get your tickets soon.

Tired of off-loading data manipulation and analysis tasks to R in your Python programs? Then you’re probably already aware of Pandas, the Python library that converts data into dataframe objects for easier manipulation. Pandas has (have?) been in pre-release for years, but there’s now a legit 1.0.0 release candidate available. Now might be the time for you Python data mungers to get onboard the Pandas Express.

And finally, the Consumer Electronics Show is a yearly gift to anyone in the tech media, providing as it does so many examples of outrageous uses for the latest technology. To wit, we have LuluPet, the world’s first feces-analyzing cat litter box. LuluPet uses a built-in camera along with IR sensors and an “AI chip” to monitor your cat’s dookie and provide an alert if anything looks awry. On the one hand, inspecting cat poop is a job we’d love to outsource, but on the other hand, most cats we know are quick to cover the evidence of their excretions with kitty litter, leaving a clay-encrusted blob rather than the turds with defined borders that would seem to be needed for image recognition to do its job. We’ll reserve judgment on this one until we see a review.
