The big news today is, of course, the successful launch and deployment of NASA’s Nancy Grace Roman Space Telescope earlier this morning. The space agency’s latest observatory lifted off at 7:26 AM Eastern from Launch Complex 39A at Kennedy Space Center aboard a SpaceX Falcon Heavy, and by 8:00 AM it was separated from the rocket’s upper stage and flying on its own.

While the sound and fury of launch is exciting, it’s just the beginning of the journey for Roman. It will take several months for the spacecraft to complete its roughly 1.5 million-kilometer trek out to Earth’s second Lagrange point (L2), where it will set up shop near — in cosmic terms, anyway — the James Webb Space Telescope (JWST). Along the way, it will switch on and test various systems and components, with its primary 300 megapixel infrared camera scheduled to power up in three weeks or so.

There’s a lot to cover about the Roman Space Telescope. Built from spy satellite spare parts donated by the National Reconnaissance Office and featuring a field of view 100 times greater than that of Hubble, its launch is widely considered to be one of the most important scientific milestones of the decade. We’ll be bringing you more about the past, present, and future of this flagship mission as it progresses.

From real space missions to virtual ones, this week the developers of EVE Online announced that 2.4 million lines of code that keep the massively multiplayer online role-playing game running would finally be making the switch to Python 3. Given the immense complexity of the codebase, it’s been stuck at Python 2.7 since their last overhaul back in 2010, a situation which has become increasingly difficult to manage as time goes on.

The announcement goes into a surprising amount of depth about the state of Python in EVE. We imagine most players couldn’t care less, but naturally the developers have strong feelings about the situation and perhaps thought it would benefit others in a similar situation to get their thoughts out there.

While there’s certainly an argument to be made that the only justification they really need for making the migration is that 2.7 hit end-of-life back in 2020, the developers explain that the more immediate problem for them was that various tools and libraries they wanted to use were no longer compatible with the Python 2.x series. They also point out hopes that speed improvements made in the latest version of Python will eventually translate into better game performance down the road.

In more terrestrial news, this week the necessary regulatory amendments were passed to make plug-in solar systems legal in the United Kingdom. Assuming the wiring meets the necessary requirements, consumers can pick up the hardware and install it themselves without involving an electrician, although they may still need to contend with landlords and local ordinances that may limit their ability to physically mount the panels. The rules as they stand now allow each residence to have four panels with a total combined output rating of no more than 2,000 watts, although critically, the system is only allowed to generate a maximum of 800 watts at the inverter. As the government and consumers get more comfortable with plug-in solar systems, these numbers will likely increase over time.

Solar isn’t the only area where DIY approaches are moving into the mainstream. This week, Citrix pitched a “different approach to endpoint resiliency”: an isolated Linux-based operating system called UniconOS that users can boot into should the computer’s primary Windows installation become compromised or otherwise inoperable. The idea is that an independent, read-only backup OS kept on its own partition will reduce downtime, since the computer can still be used while IT figures out what the hell happened.

This solution will sound suspiciously familiar to anyone who’s booted a live Linux system from CD/DVD/USB in the last few decades. Try not to keep yourself up all night wondering why you never pitched the idea to some hungry venture capitalists in exchange for a yacht in the Bahamas.

Finally, on the theme of new technology embracing the old ways, we bring you Defrag98, a web reincarnation of Microsoft’s dial-up era Disk Defragmenter tool. While it won’t actually improve the performance of your modern solid-state drive, you may find your own mood boosted by the wave of nostalgia when you see — and hear — the classic tool go to work.

That’s right, not only do the blocks dutifully flip from red to blue just like you remember, but all the while you’ll be treated to the unmistakable whirs and clicks of a spinning hard drive circa the turn of the millennium. Never forget what they took from us.

Donald Trump is presiding over an unexpected clean energy boom, as rising electricity demand spurs investment in new capacity despite the US administration’s efforts to thwart a solar and wind rollout.

Clean energy additions will rise by a record 45 gigawatts this year, according to S&P Global Energy—equivalent to the average electricity demand of Turkey. The increase is roughly 25 percent higher than the record set in 2024.

The US president’s war in Iran, which has driven up global energy prices, along with surging power demand from AI data centers and developers’ rush to capitalize on expiring tax credits, are driving the cleantech boom, said analysts. Trump’s administration has also been pragmatic in the face of its energy needs.

In this modern age, if you want a truly swish garden that makes your friends sad when they visit, you need good lighting. [technocraftStudio] has been working on just such a project, creating custom wedge lights to illuminate garden beds in style.

You might look at the plastic housings involved and assume that they’re 3D printed, like the vast majority of such projects we cover these days. Instead, the enclosures are crafted out of PVC plastic, harvested by flattening sections of pipe with a heat gun. It has the benefit of being highly weather resistant, and cheap to boot. The lights themselves are small LED panels mounted on aluminium plate as a heatsink, and fitted with an acrylic diffuser to spread the light out more evenly. Power for the lights comes from an 18650 lithium-ion cell, charged by a pair of solar panels hooked up to an MPPT charge controller. A TP223 capacitive touch module is also included in the design to allow the lights to be turned on with just the touch of a finger.

The result is a surprisingly stylish bit of garden furniture which provides warm, even light and, ideally, needs a minimum of maintenance and attention since the sun provides the power. We’ve featured some other great solar lamps before, too, like this lovely Pokemon-themed build. If you’re building your own solar projects at home, or doing weird things with PVC, we’d probably love to hear about it on the tipsline!
