Rocket Lab to launch NASA’s PREFIRE mission
NASA has announced they have selected Rocket Lab to launch their PREFIRE mission to study Earth’s climate and how the planet loses heat to space.
PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) will consist of two 6U cubesats that will be launched back to back no earlier than May 2024. The satellites will be launched from Launch Complex 1 on the Mahia Peninsula in New Zealand and inserted into a 525 km (326 miles) polar orbit that will take it over the Artic and Antarctic ice caps.
Two Electron launches, one very important climate change mission for @NASA.
PREFIRE will study Arctic warming to help researchers fight against rising sea levels and melting ice sheets.

These cubesats will be the 7th and 8th missions that Rocket Lab has launched for NASA, and due to the strict mission requirements, they are the only dedicated small satellite launch company capable of rapid back-to-back launches that are needed for this mission.
The PREFIRE cubesats, once in orbit, will deploy two solar arrays each before beginning science observations. The cubesats will measure how much heat is lost through the atmosphere to space from the ice caps and help predict future ice melt, which results in rising sea levels and coastal erosion around the planet.

The launch contract was awarded under NASA’s VADR (Venture-class Acquisition of Dedicated and Rideshare) launch services which are based at NASA’s Kennedy Space Center in Florida. NASA’s Jet Propulsion Laboratory will manage the mission and is providing the instruments, while the University of Wisconsin-Madison will process the data collected. The main cubesats will be built by Blue Canyon Technologies.

Tesla Model Y on FSD saves couple after encountering King of edge cases
Experts have noted that if confirmed, this could be the world’s first recorded meteorite collision involving a Tesla.
A South Australian Tesla driver is thanking his Model Y’s Full Self-Driving system after a mysterious object, possibly a meteorite, slammed into his car’s windshield while it had FSD engaged.
The impact sent hot glass fragments flying through the cabin as the vehicle continued driving without human input through the darkness. Experts have noted that if confirmed, this could be the world’s first recorded meteorite collision involving a Tesla.
The Tesla owner was enjoying a quiet drive home when they hit the king of edge cases
Veterinarian Dr. Andrew Melville-Smith and his wife were traveling north on Augusta Highway on the night of October 19 when a sudden blast struck their newly delivered Model Y. At the time, it was clear, pitch black night, and Dr. Melville-Smith and his wife were just listening to a podcast while FSD was operating the vehicle, as noted in a Yahoo News report.
Suddenly, something hit the Tesla’s windshield. “Then there was, (what) I can only describe as a very, very violent explosion. The whole inside of the car was literally blasted with glass fragments. It was full of white smoke, and it smelled like the car was on fire,” Dr. Melville-Smith stated.
The vet stated that he and his wife were stunned for a good 10 seconds, and for a bit, he and his wife thought they had crashed. Images of the crash’s aftermath showed a massive crack on the Tesla’s windshield, which Dr. Melville-Smith noted was hot to the touch. The object that hit the Tesla’s windshield was so hot that part of the vehicle’s windshield was partly melted.
FSD kept driving despite the possible meteorite strike
Thankfully, the Tesla was operating with its FSD (Supervised) system engaged at the time. Thus, despite the vehicle being hit by what might be a literal meteorite, and despite Dr. Melville-Smith and his wife being stunned because of the impact, their Tesla just kept driving steadily.
“I thought we’d had an accident, but then I looked at the screen and went ‘Oh, we’re still driving. We were moving around, so it obviously thought we were paying attention, and it was happy to keep driving to Port Augusta. After we pulled over, we saw the big crater in the windscreen,” the vet said.
The South Australian Museum is now examining the case, with geologist Dr. Kieran Meaney stating the scorched glass and heat damage do suggest a potential meteorite strike. “The little detail that’s really selling it for me at the moment is that whatever it was that hit the windscreen seems to have been very hot,” Meaney explained. However, the object has yet to be recovered.

“Foundation:” Elon Musk wants to send a record of Grokipedia to space
The idea sounds outlandish, though it is also something that is in character for the CEO.
Elon Musk has announced one of his latest initiatives, and it is every bit as sci-fi as it is surprisingly grounded. In a post on X, Musk stated that Grokipedia, xAI’s new open-source encyclopedia, will be etched into stable oxide and launched into space.
The idea sounds outlandish, though it is also something that is in character for the CEO.
Preserving human knowledge among the stars
Musk posted his plan following the launch of Grokipedia’s V0.1’s iteration. The CEO congratulated the xAI team for the online encyclopedia’s launch, though he also stated that the goal for Grokipedia is to create an open-source collection of knowledge. This would then be distributed to the cosmos.
“Nice work by the xAI team on Grokipedia! The goal here is to create an open source, comprehensive collection of all knowledge. Then place copies of that etched in a stable oxide in orbit, the Moon, and Mars to preserve it for the future. Foundation,” Musk wrote in his post.
While seemingly outlandish, this is not the first time that a record of human knowledge of sorts was sent out to space. In 1977, the Voyager Golden Record was launched aboard NASA’s Voyager 1 and 2 spacecraft. The record contains sounds and images that ere aggregated to portray the diversity of the Earth’s culture. Of course, Musk’s plan with Grokipedia, is infinitely more ambitious.
Grokipedia and AI neutrality
Musk launched Grokipedia as an AI-driven alternative to Wikipedia, designed to eliminate the human biases that could affect conventional online knowledge platforms. The system is powered by xAI’s Grok, which scrape and summarize information from across the internet, offering balanced and nuanced coverage of topics ranging from science and technology to culture and politics.
Unlike Wikipedia’s human-edited format, Grokipedia would be able to evolve through machine learning, reading vastly more material than any editorial team could. Early testers, including Wikipedia co-founder Larry Sanger, praised its initial version as “very OK” and potentially more neutral than Wikipedia. Musk agreed, stating that even in its V0.1 form, Grokipedia is “already better than Wikipedia.”

Tesla Cybertrucks to save Las Vegas police thousands in fuel and maintenance
Sheriff Kevin McMahill unveiled the new vehicles on Monday, describing them as “the next evolution to keep our community safer than it’s ever been.”
The Las Vegas Metropolitan Police Department has officially unveiled its fleet of Tesla Cybertrucks as part of its push toward a more advanced, cost-efficient, and sustainable patrol system.
Sheriff Kevin McMahill unveiled the new vehicles on Monday, describing them as “the next evolution to keep our community safer than it’s ever been.” The trucks are expected to begin service across all area commands within two weeks.
High-tech patrol fleet
Each UP.FIT-modified Cybertruck has been customized with ladders, shields, and less-lethal equipment to support law enforcement operations. The vehicles will connect to a live drone response hub capable of facial recognition and gunshot detection, enabling drones to launch automatically when alerts trigger. The system streams real-time footage directly to responding officers, enhancing both speed and situational awareness during emergencies.
Officers have already completed training with the new fleet and offered feedback on its performance, according to Fox 5 Vegas. Sheriff McMahill noted that the trucks, along with robot dogs and SWAT vehicles, represent a coordinated effort to combine human expertise with emerging technologies. The Cybertruck rollout was made possible through a donation from the Horowitz family.
Cybertrucks’ major savings
The department’s ten UP.FIT patrol Cybertrucks are among the most American-made law enforcement vehicles available, featuring roughly twice the domestic parts content of comparable Ford and Chevrolet patrol trucks. Beyond their build quality, the electric fleet offers major cost benefits. Each Cybertruck is projected to save between $8,800 and $12,000 in annual fuel costs and roughly $3,540 in maintenance over a five-year service life.
With regenerative braking, factory ballistic-resistant doors, and no idling fuel burn, the Cybertruck platform provides higher uptime, lower total cost of ownership, and a quieter patrol experience, all while reducing the department’s carbon footprint. Sheriff McMahill confirmed each area command will receive one of the new patrol units.
