SpaceX to launch NASA’s SWOT water topography satellite on reused Falcon 9

Published

on

NASA has modified a contract with SpaceX to allow the company to launch the international Surface Water and Ocean Topography (SWOT) mission on a flight-proven Falcon 9 booster.

NASA announced its original decision more than half a decade ago. The agency awarded SpaceX an unusually expensive $112 million contract in November 2016 to launch SWOT on a Falcon 9 rocket in April 2021. SWOT is expected to weigh less than two tons (~4400 lb) and is headed to a simple low Earth orbit (LEO), meaning that the launch won’t be particularly challenging or performance-intensive for SpaceX or Falcon 9. Most importantly, the company will almost certainly be able to recover the mission’s Falcon 9 booster and may be able to perform a return-to-launch-site landing for even greater cost-efficiency.

SWOT’s launch should be almost identical to Sentinel 6A, a similarly light spacecraft that SpaceX successfully delivered to a similar orbit from the same launch pad in November 2020. In fact, both SWOT and Sentinel 6A are essentially flying altimeters designed to use radar to measure the surface height of Earth’s oceans and other bodies of water. Both also carry microwave-based instruments to determine the amount of water vapor present in Earth’s atmosphere. While Sentinel 6A was largely built by France’s CNES space agency, SWOT is a bit more collaborative, with NASA’s Jet Propulsion laboratory providing the main altimeter instrument and completing a significant amount of preliminary integration work.

Nonetheless, SWOT’s parts are sent to CNES facilities in France for final integration. Currently scheduled to launch no earlier than November 2022 after a roughly 1.5-year delay, SWOT will need to be delivered from France to California at least a month or two prior to liftoff in order to begin final launch preparations. It remains to be seen if the mission will avoid additional delays in the interim. Prior to most of the mission’s recent delays, NASA’s Office of the Inspector General (OIG) estimated [PDF] that SWOT would cost its partners around $1.15 billion over the spacecraft’s lifetime. Sentinel 6A’s total cost is also expected to be around $1.1 billion.

Once launched, SWOT will operate in a circular ~890-kilometer (~550 mi) orbit with an inclination of around 78 degrees, allowing the spacecraft to singlehandedly observe 86% of Earth’s surface. Sentinel 6A operates in a slightly higher 1336-kilometer (830 mi) orbit at a 66-degree inclination and will eventually be joined by a second spacecraft to enable full global coverage.

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.”

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.
