Italy Proposes Minimalist Lunar Outpost For Artemis

December 4, 2023 by Tom Nardi 26 Comments

When humanity first step foot on the Moon, they couldn’t stay around for very long. The Apollo program was limited by the technology of the era — given the incredible cost per kilogram to put a payload down on the lunar surface, it wasn’t feasible to bring down enough consumables for a lengthy stay. Even if they could have carried sufficient food and water to last more than a few days, the limiting factor would have become how long the crew could realistically remain cooped up in the tiny Lunar Excursion Module (LEM).

In comparison, the Artemis program is far more ambitious. NASA wants to establish a long-term, and perhaps even permanent, human presence on our nearest celestial neighbor. This will be made possible, at least in part, to the greatly reduced launch costs offered by current and near-future launch vehicles compared to legacy platforms like the Saturn V or Space Shuttle. But cheaper rides to space is only part of the equation. NASA will also be leaning heavily on the lessons learned during the International Space Program; namely, the advantages of modular design and international cooperation.

While NASA and their commercial partners will still end up providing the bulk of the hardware for the Artemis program, many modules and components are being provided by other countries. From the Orion’s European Service Module (ESM) to the Japanese life support systems to be installed on the Lunar Gateway Station, America won’t be going to the Moon alone this time.

The latest international contribution to the Artemis program comes from the Italian Space Agency (ASI), who have announced their intention to develop a lunar habitation module they’re calling the Multi-Purpose Habitat (MPH) in collaboration with Thales Alenia Space.

G-code Goes Binary With Proposed New Format

November 28, 2023 by Donald Papp 66 Comments

G-code is effective, easily edited, and nearly ubiquitous when it comes to anything CNC. The format has many strengths, but space efficiency isn’t one of them. In fact, when it comes to 3D printing in particular file sizes can get awfully large. Partly to address this, Prusa have proposed a new .bgcode binary G-code format. You can read the specification of the new (and optional) format here.

The newest version of PrusaSlicer has support for .bgcode, and a utility to convert ASCII G-code to binary (and back) is in the File menu. Want to code an interface of your own? The libbgcode repository provides everything needed to flip .gcode to .bgcode (with a huge file size savings in the process) and vice versa in a way that preserves all aspects of the data. Need to hand-edit a binary G-code file? Convert it to ASCII G-code, make your changes, then flip it right back.

Prusa are not the only ones to notice that the space inefficiency of the G-code file format is not ideal in all situations. Heatshrink and MeatPack are two other solutions in this space with their own strong points. Handily, the command-line tool in libgcode can optionally apply Heatshrink compression or MeatPack encoding in the conversion process.

In a way, G-code is the assembly language of 3D printers. G-code files are normally created when slicing software processes a 3D model, but there are some interesting tricks to be done when G-code is created directly.

Proposed European Electronic ID Law Raises Concerns

November 2, 2023 by Jenny List 39 Comments

The harmonisation of standards for electronic identification across the EU should normally be soporific enough to send even the most Club-Mate-hyped hacker straight to sleep, but as Computer Weekly reports, discussion of this reform in the EU corridors of power has caused significant unrest among cyber security experts. Just how can providing Europeans with a harmonised digital ID be so controversial? As you might imagine, the devil lies in the detail.

At issue is the eIDAS Regulation, a system which, in the words of its website: “ensures that people and businesses can use their own national electronic identification schemes (eIDs) to access public services available online in other EU countries,” and “creates a European internal market for trust services by ensuring that they will work across borders and have the same legal status as their traditional paper-based equivalents,” and the point of concern lies with its application to websites. The EU want to ensure that Europeans can digitally verify businesses as well as individuals they deal with, and since that includes websites, they want to insert a provision allowing countries to mandate their own trusted root certificates. At a stroke, this opens the potential for state actors to snoop on all encrypted online traffic, something which would compromise the security of all.

Sadly for Europeans, this isn’t the only questionable online regulation effort from that region.

Europe’s Proposed Right-To-Repair Law: A Game Changer, Or Business As Usual?

March 27, 2023 by Maya Posch 145 Comments

Recently, the European Commission (EC) adopted a new proposal intended to enable and promote the repair of a range of consumer goods, including household devices like vacuum cleaners and washing machines, as well as electronic devices such as smartphones and televisions. Depending on how the European Parliament and Council vote in the next steps, this proposal may shape many details of how devices we regularly interact with work, and how they can be repaired when they no longer do.

As we have seen recently with the Digital Fair Repair Act in New York, which was signed into law last year, the devil is as always in the details. In the case of the New York bill, the original intent of enabling low-level repairs on defective devices got hamstrung by added exceptions and loopholes that essentially meant that entire industries and types of repairs were excluded. Another example of ‘right to repair’ being essentially gamed involves Apple’s much-maligned ‘self repair’ program, that is both limited and expensive.

So what are the chances that the EU will succeed where the US has not?

Non-Replaceable Battery? Not If This Proposed EU Law Passes!

December 24, 2022 by Jenny List 104 Comments

A disturbing trend in consumer electronics has been a steady disappearance of replaceable batteries on our devices. Finding a mobile phone with a swapable battery is a struggle, and many other devices follow the trend by sealing in a Li-Po cell. The result is an ever-shorter life for electronics, and a greater problem with devices going to recycling or worse still, landfill. Hope is at hand though, thanks to a proposed European Union law that would if passed make batteries in appliances “designed so that consumers can easily remove and replace them themselves“.

In case any readers in the rest of the world wonder what it has to do with them, the EU represents such a huge market that manufacturers can neither ignore it, nor in most cases afford to make separate EU and rest-of-world versions of their products. Thus if the EU requires something for sale in its territories, in most cases it becomes the de facto norm for anything designed to be sold worldwide. We’ve already seen this with the EU’s right to repair legislation, and while we have not doubt that manufacturers will do their best to impede this new law we don’t think they will ultimately prevail.

Proposed NASA Budget Signals Changes To Space Launch System

March 13, 2019 by Brian Benchoff 17 Comments

The White House’s proposed budget for 2020 is out, and with it comes cuts to NASA. The most important item of note in the proposed budget is a delay of the Space Launch System, the SLS, a super-heavy lifting launch vehicle designed for single use. The proposed delay would defer work on the enhanced version of the SLS, the Block 1B with the Exploration Upper Stage.

The current plans for the Space Launch System include a flight using NASA’s Orion spacecraft in June 2020 for a flight around the moon. This uncrewed flight, Exploration Mission 1, or EM-1, would use the SLS Block 1 Crew rocket. A later flight, EM-2, would fly a crewed Orion capsule around the moon in 2022. A third proposed flight in 2023 would send the Europa Clipper to Jupiter. The proposed 2020 budget puts these flights in jeopardy.

FAA Proposes Refined Drone Regulations

February 4, 2019 by Tom Nardi 77 Comments

The wheels of government move slowly, far slower than the pace at which modern technology is evolving. So it’s not uncommon for laws and regulations to significantly lag behind the technology they’re aimed at reigning in. This can lead to something of a “Wild West” situation, which could either be seen as a good or bad thing depending on what side of the fence you’re on.

In the United States, it’s fair to say that we’ve officially moved past the “Wild West” stage when it comes to drone regulations. Which is not to say that remotely controlled (RC) aircraft were unregulated previously, but that the rules which governed them simply couldn’t keep up with the rapid evolution of the technology we’ve seen over the last few years. The previous FAA regulations for remotely operated aircraft were written in an era where RC flights were lower and slower, and long before remote video technology moved the operator out of the line of sight of their craft.

To address the spike in not only the capability of RC aircraft but their popularity, the Federal Aviation Administration was finally given the authority to oversee what are officially known as Unmanned Aerial Systems (UAS) with the repeal of Section 336 in the FAA Reauthorization Act of 2018. Section 336, known as the “Special Rule for Model Aircraft” was previously put in place to ensure the FAA’s authority was limited to “real” aircraft, and that small hobby RC aircraft would not be subject to the same scrutiny as their full-size counterparts. With Section 336 gone, one could interpret the new FAA directives as holding manned and unmanned aircraft and their operators to the same standards; an unreasonable position that many in the hobby strongly rejected.

At the time, the FAA argued that the repealing Section 336 would allow them to create new UAS regulations from a position of strength. In other words, start with harsh limits and regulations, and begin to whittle them down until a balance is found that everyone is happy with. U.S. Secretary of Transportation Elaine L. Chao has revealed the first of these refined rules are being worked on, and while they aren’t yet official, it seems like the FAA is keeping to their word of trying to find a reasonable middle ground for hobby fliers.
