Submission + - SpaceX engineer says NASA should plan for Starship's "significant" capability (arstechnica.com)

technology_dude writes: As part of its Artemis program to return humans to the Moon this decade, NASA has a minimum requirement that its "human landing system" must be able to deliver 865 kg to the lunar surface. This is based on the mass of two crew members and their equipment needed for a short stay.

However, in selecting SpaceX's Starship vehicle to serve as its human lander, NASA has chosen a system with a lot more capability. Starship will, in fact, be able to deliver 100 metric tons to the surface of the Moon—more than 100 times NASA's baseline goal.

"Starship can land 100 tons on the lunar surface," said Aarti Matthews, Starship Human Landing System program manager for SpaceX. "And it’s really hard to think about what that means in a tangible way. One hundred tons is four fire trucks. It’s 100 Moon rovers. My favorite way to explain this to my kids is that it's the weight of more than 11 elephants."

The engineer says NASA is not thinking big enough. I think it's pretty obvious what the payload should be, a nuclear powered boring machine. With flame thrower weapons just in case!

Leave a comment for my resume. Maybe I'll call.

Submission + - SPAM: FAA delays environmental review of SpaceX's Starship yet another month, to May31

schwit1 writes: We'll have to wait at least another month to see the results of the U.S Federal Aviation Administration's (FAA) environmental review of SpaceX's Starship program.

The FAA has been working for months on that review — officially known as a programmatic environmental assessment (PEA) —which is assessing the environmental impacts of Starbase, the South Texas site where SpaceX has been building and testing its huge Starship vehicle.

The agency published a draft PEA in September and estimated that the final version would be wrapped up by the end of the year. But the FAA has repeatedly delayed the final PEA, generally by a month at a time, citing the need to analyze the public comments submitted in response to the draft report and discuss next steps with other government agencies.

Submission + - Conway Conjecture Settled after 29-years (hatsya.com)

joshuark writes: Ilkka Törmä and Ville Salo, a pair of researchers at the University of Turku in Finland, have found a finite configuration in Conway’s Game of Life such that, if it occurs within a universe at time T, it must have existed in that same position at time T1 (and therefore, by induction, at time 0).

Submission + - Email provider used by millions suddenly disappears from the internet 1

C4st13v4n14 writes: Since Tuesday evening local time, I haven't been able to access my primary email account. This is an alumni email account I've had for the last 22 years that's tied to all my accounts ranging from not only social media and IOT devices, but also banking, access to health services and contact with local and countrywide government authorities. My country is highly digitised and virtually everything from taxes to buying or selling a house, paying bills, access to health records and correspondence with hospitals and GPs, driving licences, applying for welfare, and starting a business are online. I don't even get snail mail anymore, everything is sent to a digital mailbox I can access through a browser or app with 2FA. Fortunately, all access control for public-facing services is via 2FA or smartcards with secure certificates for the highly sensitive stuff. Regardless, the ordeal has been quite distressing as I was unable to find any information about the outage; a little detective work was only giving vague ERR_CONNECTION_RESET and DNS errors.

My main thought was that my account had somehow been compromised and even more worryingly, there were no reports online about it. Turning to reddit, I was able to gather that the provider, Mail2World, had suffered a ransomware attack but had been very uncommunicative about the event. In terms of news coverage, there was basically none. Only one random news site had a short article about it. During the days without access, I was painstakingly moving accounts to my Gmail address and updating contact information for the really important stuff like governmental services. This morning, I got a tip that Jesse over at BlueScreen Computer had reached out to Mail2World and been documenting the outage. Since then, some email has started to show up in my mobile app and I'm able to access the web portal again, but I can't help but feel like the damage has been done. This is an account that I pay an annual fee for and have trusted to work until now. I also find being kept in the dark about something so fundamental in today's world like email to be both very concerning and completely unacceptable. In that regard, I'm hoping this will bring some coverage to the event. I would also like any input you Slashdotters have on migrating to and navigating Gmail. The interface is unfamiliar to an old-school user like me who still uses Eudora to check and save a backup of everything. By the way, I'd should also like to point out that both POP and SMTP are handled by servers at pangia.biz, and their website has also been unreachable during this. Instead of Gmail, maybe you would recommend a different provider or service altogether? My work email is fortunately completely separate as of a couple years ago and handled by one.com as they host my website. It works, but they aren't anything special really.

Submission + - SPAM: Mossad assassinated Iran's chief nuke scientist with remote AI gun 2

PolygamousRanchKid writes: Iran’s chief military nuclear scientist and the father of its weapons program, Mohsen Fakhrizadeh, was assassinated in November 2020 by the Mossad using a remote-controlled artificial intelligence operated sniper machine gun, The New York Times reported on Saturday. According to the report, “Iranian agents working for the Mossad had parked a blue Nissan Zamyad pickup truck on the side of the road connecting the town of Absard to the main highway. Hidden beneath tarpaulins and decoy construction material in the truck bed was a 7.62-mm sniper machine gun.”

The report details how the sniper who took out Fakhrizadeh did so remotely from Israel, over 1,600 kilometers away, since the hit squad had long ago left Iran. The gun which was used was a special model of a Belgian-made FN MAG machine gun attached to an advanced robotic apparatus. It was smuggled into the country in small pieces over several months because, taken together, all of its components would have weighed around a full ton.

Comment Re:No Consciousness? (Score 1) 83

But it is quite easy to see and prove the Earth is not flat, as it involves well understood physics.

Consciousness is a much more difficult phenomenon that is not at all well understood.
So making definitive statements about it as as the poster I replied to did is not warranted.
And it probably a good idea to be a bit more cautious and also consider some opposing views.

thephydes writes: Japanese Coast Guard said on Monday that a new ivolcanic sland has appeared about 1200km south of Tokyo

"The new island is C-shaped with a diameter of approximately 1 kilometer. It was discovered after the volcano some 50 km south of Iwo Jima, part of the Ogasawara Islands in the Pacific Ocean, started erupting on Friday."

Submission + - SPAM: Windbreaks, surprisingly, could help wind farms boost power output

labloke11 writes: Windbreaks may sound like a counterintuitive idea for boosting the performance of a wind turbine. But physicists report that low walls that block wind could actually help wind farms produce more power.

Scientists already knew that the output of a single wind turbine could be improved with a windbreak. While windbreaks slow wind speed close to the ground, above the height of the windbreak, wind speeds actually increase as air rushes over the top. But for large wind farms, there’s a drawback. A windbreak’s wake slows the flow of air as it travels farther through the rows of turbines. That could suggest that windbreaks would be a wash for wind farms with many turbines.

But by striking a balance between these competing effects, windbreaks placed in front of each turbine can increase power output, new computer simulations suggest. It comes down to the windbreaks’ dimensions. Squat, wide barriers are the way to go, according to a simulated wind farm with six rows of turbines. To optimize performance, windbreaks should be a tenth the height of the turbine and at least five times the width of the blades, physicists report July 30 in Physical Review Fluids. Such an arrangement could increase the total power by about 10 percent, the researchers found. That’s the equivalent of adding an additional turbine, on average, for every 10 in a wind farm.

In the simulations, the wind always came from the same direction, suggesting the technique might be useful in locations where wind tends to blow one way, such as coastal regions. Future studies could investigate how this technique might apply in places where wind direction varies.

Submission + - SPAM: AMD's Radeon RX 6600 XT Launched To Compete Versus NVIDIA GeForce RTX 3060

MojoKid writes: AMD officially unveiled the Radeon RX 6600 XT in late July but the cards have officially launched today, aimed at 1080p gaming. In a review at HotHardware, PowerColor is offering both a high-end Radeon RX 6600 XT Red Devil and its somewhat more mainstream "Fighter" branded counterpart, for example. Whereas AMD's reference Radeon RX 6600 XT offers a Game clock up to 2359MHz and a Boost clock of 25895MHz, the PowerColor Red Devil peaks at 2428MHz (Game) and 2607MHz (Boost). Those higher GPU clocks result in higher compute performance and fillrate, etc., but the memory configuration and frequency are the same — so in memory bandwidth constrained situations, performance won't be all that much different. Performance-wise, with most game titles that use traditional rasterization, the Radeon RX 6600 XT is clearly faster than the GeForce RTX 3060 and previous-gen cards like the Radeon RX 5700 XT or GeForce RTX 2060 Super. However, when you factor ray tracing into the equation, NVIDIA has a distinct and significant advantage still. The Radeon RX 6600 XT Fighter should sell for at or close to its $379 MSRP and PowerColor says that they should be readily available for gamers to purchase today.
