All you have to do is upload an STL file and set sliders to get rid of as many triangles as you want. The tool is pretty neat it uses three.js and runs completely in-browser. If you like the look of low-poly models but hate the work involved in making them, our friend and Hack Chat alumnus Andrew Sink came up with a solution: an online 3D low-poly generator. The designs are all up on GitHub, so check it out and think about what else this could be useful for. If you get separated from your machine, the dongle sends customizable commands to either lock the screen or, for the sufficiently paranoid, nuke the hard drive. A dongle with a breakaway magnetic lanyard gets plugged into a USB port, and the other end of the lanyard gets attached to your person.

It’s a hardware-software approach to securing a laptop when it - or you - suddenly goes missing. That’s where BusKill could come in handy. But what if it got yoinked while it was unlocked? Depending on who you are and what you do with that machine, it could be a death sentence. But then again, if you’re going to find evidence of life on Mars, you’ve got to start with detecting organics.īack on Earth, getting your laptop stolen would be bad enough. The organics found are not proof of life by any means, as there are many ways to make organic molecules abiotically. But the latest evidence is really great news for the scientists who picked Jezero crater as a likely place to search for signs of past life on Mars. It’s not the first time organic compounds have been found - Perseverance’s cousin Curiosity found some too, ESA’s Mars Express mission spotted methane from on high, and then there were the equivocal but intriguing results from the Viking missions in the 1970s. Meanwhile, in Jezero crater, Perseverance has decided to upstage its rotorcraft sidekick for a change by finding signs of organic molecules on Mars. The Mariner Valley stretches more than 4,000 km just below the equator, and so may prove to be an important resource for future explorers. If so, that’s a huge find, as we thought most of Mars’ water was locked in the polar regions. The satellite found a large area of increased hydrogen concentration in the top meter of Martian soil the assumption is that the hydrogen comes from water, meaning that as much as 40% of the material in the region scanned may be water.

The ESA announced that their ExoMars Trace Gas Orbiter has detected signs of water in the Valles Marineris. In other space news, things are getting really interesting on Mars. Either way, here’s hoping that everything comes off without a hitch, and that astronomers get the present they’ve been waiting many, many Christmases for. Given the exigencies of the day, we doubt we’ll be able to watch the launch live - then again, past experience indicates we’ll still be wrapping presents at 4:20 PST. The $10 billion space observatory suffered one final delay (knocks on wood) when predictions of high winds aloft pushed it back from a Christmas Eve launch to a Christmas Day departure, at 12:20 UTC. At the time of this writing, the James Webb Space Telescope was perched upon its ride to space, ready for its much-delayed launch from the ESA spaceport in French Guiana.
