As reported by Electrek: Unplugged Performance has brought its brand-new Tesla Model S Plaid to the Pikes Peak Hill Climb, and the new top-performance electric vehicle is already impressing in the practice round.
After famously crashing their Model 3 and building it back up in record time to compete last year, Unplugged Performance is back at Pikes Peak, but this time with a brand-new Model S Plaid.
It’s going to be the first time Tesla’s new top performance vehicle is being put to the test, and it’s no easy test.
Pikes Peak consists of a 12.4-mile route that starts at just above 9,000 feet and climbs to the summit at 14,115 feet above sea level.
It’s not only extremely dangerous for the driver since the sharp turns mostly open up to the sides of cliffs, but it’s also extremely demanding on the vehicles competing.
As we previously reported, Unplugged Performance, a Tesla tuner and aftermarket accessory maker, managed to get their hands on an early Tesla Model S Plaid, which they modified with a new suspension, brakes, tires, roll cage, and a few aerodynamic changes.
They released a video of the vehicle during the practice runs at the Pikes Peak Hill Climb:
It is leading its division (exhibition) by a decent margin, and it’s getting close to the times of some purpose-built vehicles in the open wheel category:
Those times are only for one section of the route that is open for practice.
While he wasn’t pushing it too hard, he was able to hit 130 mph in some stretches of the climb, which is simply insane:
It’s going to be interesting to see what time Unplugged Performance can get with their modified Tesla Model S Plaid, which stock can accelerate from 0 to 60 mph in less than two seconds.
As reported by SlashGear: An incredible network of lunar satellites, ringing the Moon and powering a telecoms and navigation system there, is another step closer to reality, the European Space Agency has announced today. The ESA’s Moonlight plan would address one of the growing areas of concern as humanity plans a crewed return to the lunar surface, delivering stable communications between teams and back with mission control on Earth.
Currently, communications between the Moon and Earth are fairly bottlenecked. The Moon itself blocks radio signals, which means that any probe, spacecraft, or crewed mission to the far-side of Earth’s satellite is cut off from direct transmissions to and from us.
China’s Chang’e-4 lander, for example, relied upon a relay satellite in the Earth-Moon L2 Lagrangian point. That satellite, Queqiao, effectively acts as an intermediary, taking communications from the lander and then relaying them to Earth. What the ESA has in mind, though, is considerably more complex – and more powerful.
A series of satellites positioned around the Moon could blanket it in coverage, both for communications and for a GPS-style navigation system. It would avoid the need for lunar missions to establish a relay of their own, or use high-power transmitters capable of reaching Earth independently. As a result, the ESA suggests, future missions could be even more accessible.
“Using a shared telecommunications and navigation service would reduce the design complexity of future individual missions and make them lighter, freeing space for more scientific instruments or other cargo, making each individual mission more cost-efficient,” the Agency points out.
“Lowering the ticket price to lunar exploration could empower a wider group of ESA member states to launch their own national lunar missions,” it’s suggested. “Even on a relatively low budget, an emerging space nation would be able to send a scientific CubeSat mission to the Moon, inspiring the next generation of scientists and engineers.”
To begin with, the ESA plans to demonstrate the potential of such a system with the Lunar Pathfinder comsat. Set to launch by the end of 2023, it’ll establish an orbit around the Moon and deliver navigation and data relay information. The goal is positioning accuracy of around 100 meters, though future satellites could halve that or better.
The ESA is also providing NASA with the ESPRIT communications module for the upcoming Artemis program. Moonlight will tap technologies from both those projects, to build out a lasting network for the Moon.
It’ll take a while, unsurprisingly, for that to be realized. The ESA has just inked deals with two consortia – one led by Surrey Satellite Technology Ltd, working with Airbus and others; the other led by Telespazio, working with Inmarsat, Canada’s MDA, and others – to figure out the logistics and details.
“A robust, reliable and efficient telecommunications and navigation system will make the dozens of individual missions planned for the Moon more cost-efficient and enable smaller countries to become space-faring nations, inspiring the next generation of scientists and engineers,” Elodie Viau, Director of Telecommunications and Integrated Applications at the ESA, said today of the agreements.
NASA’s Artemis mission aims to return astronauts to the surface of the Moon by 2024. It also intends to build a Lunar Gateway, a new space station positioned near the Moon, which would act as a staging post both for lunar descent and – in future – missions further afield to Mars and other planets in our solar system.
The Parker Solar Probe was clocked at over 330,000 miles per hour as it zipped through the sun's outer atmosphere.
As reported by C/NET: Nothing built by human hands has ever travelled faster than NASA's Parker Solar Probe, a diminutive, scorch-proof spacecraft about the size of a small car is practically "touching the sun." In late April, it smashed two wild space records, dethroning the previous champion -- which also happened to be NASA's Parker Solar Probe -- and its journey is really just beginning.
The probe, which launched in August 2018 on a mission to study the sun, has been flying ever closer to our solar system's furnace using the planet Venus as a slingshot. On April 29, during its closest approach to the sun (known as "perihelion"), Parker was traveling at an almost unfathomable speed -- enough to circle the Earth 13 times in a single hour.
Closest spacecraft to the sun: 6.5 million miles (10.4 million kilometers).
Those are some strong records to hold and this isn't the end, either. Parker should break its own record later in the year when it uses another Venus flyby to slingshot closer to the sun. Perihelion is expected to occur on Nov. 21.
As reported by Yahoo!Finance: The winner of NASA's Human Landing System (HLS) contract award is SpaceX, which bid $2.9 billion for the privilege of developing the means by which NASA astronauts will return to the lunar surface for the first time since the Apollo program. SpaceX was in the running alongside Blue Origin and Dynetics, but reportedly undercut both those prospective suppliers considerably with its bid, according to The Washington Post.
SpaceX proposed using its Starship spacecraft, currently under development, as the landing vehicle for astronauts once they arrive at their lunar destination. The HLS is a key part of NASA's Artemis program, which will begin with uncrewed flights, followed by a Moon fly-by with a human crew, and eventually a human lunar landing at the South Pole of the Moon, during a mission which had been targeting 2024 as its fly date.
NASA announced that SpaceX, Blue Origin and Dynetics made up the entirety of its field of approved vendors for bidding on the HLS contracts back in April last year. Since then, both Blue Origin (which bid alongside a "national team" that included Lockheed Martin, Northrop Grumman and Draper) and Dynetics have built full-scale models of their system and submitted proposals detailing their plans for the functional versions to NASA for consideration. Meanwhile, SpaceX has been actively testing functional prototypes of its Starship spacecraft in Texas, and is also in the process of developing the Super Heavy booster that will propel it to the Moon once it's ready.
The plan here was for NASA to have chosen all three companies to build out initial versions in order to satisfy the early requirements of the contract, and then ultimately, it was generally thought that the agency would select a couple from the list of three to build human landers, in order to provide it with some flexibility when it comes to means of getting to the lunar surface. That's essentially how NASA operated with its Commercial Crew program for the International Space Station, which saw awards for both SpaceX and Boeing to build astronaut transport spacecraft. SpaceX has already qualified and begun to operate its vehicle, and Boeing hopes to bring its option online either late this year or early next.
SpaceX has won a lot of trust at NASA by delivering on the Commercial Crew program with a reliable, reusable human-rated spacecraft in the Crew Dragon. The Post also says that in addition to its attractive pricing, NASA wasn't drawn to Starship's flexibility and cargo capacity, since it's aiming to be able to fly not just humans, but also large quantities of supplies and materials to the Moon, and eventually, beyond.
Starship is a long way off from that goal at the moment, however; SpaceX has been quickly developing new iterations in a rapid prototyping approach to its test phase, but the most recent Starship high-altitude flight ended poorly with an explosion prior to landing. Other elements of the test program, however, including showing that Starship can successfully reorient itself in mid-air and slow its decent for landing, have been more successful on past tests. None of the tests so far have left Earth's atmosphere, however, nor have they involved any human flight testing, both of which will require a lot more development before the spacecraft is deemed mission-ready.
SpaceX was also the launch provider chosen to deliver components of the Lunar Gateway satellite in 2024, working with Maxar, which will produce the actual Power and Propulsion Element and Habitation and Logistics Outpost. These, however, will be delivered via Falcon Heavy, which has already had multiple successful launches.
As reported by SeattleTimes: UPS is ordering 10 electric aircraft that are designed to take off and land like a helicopter, allowing it to fly cargo directly between its facilities in small markets and bypass airports.
The electric Vertical Takeoff and Landing (eVTOL) aircraft made by Beta Technologies would be flown by an onboard pilot when UPS begins getting them in 2024, pending Federal Aviation Administration certification. Burlington, Vermont-based Beta Technologies is conducting flight testing on the aircraft at a test facility in Plattsburgh, N.Y.
But the aircraft are designed to “someday operate autonomously” once the technology and regulations are developed, according to Sandy Springs, Georgia-based UPS, which did not disclose the purchase price.
UPS has an option to purchase an additional 140 aircraft. It plans “to take delivery and see how they perform within the network, and then move from there,” said UPS spokesman Matthew O’Connor.
After years of testing drone delivery technologies, UPS in 2019 got Federal Aviation Administration approval for a drone airline called UPS Flight Forward and has partnered with CVS for prescription drone deliveries. In recent years, UPS has also tested self-driving tractor-trailers and vans, ordered 10,000 electric delivery trucks and worked to develop electric vehicles capable of automated movement in UPS depots.
The eVTOL aircraft would be used to supplement cargo shipments in UPS’s small feeder air network, currently served by contract operators that use Beechcraft and Cessna 208 Caravan planes to fly cargo between small and medium-sized markets.
The Beta aircraft have a 1,400-pound cargo capacity, the Associated Press reported.
Since the eVTOL aircraft would be able to take off and land at UPS facilities, the company would save the time and labor for loading and transferring at airports between planes and trucks that drive the packages to UPS facilities. That could speed urgent shipments such as pharmaceuticals and documents.
“By utilizing vertical takeoffs and landings, we can turn relatively small spaces at existing UPS facilities into a micro air feeder network without the noise or operating emissions of traditional aircraft,” said Beta founder and CEO Kyle Clark in a written statement.
The Beta Technologies eVTOL aircraft are designed to have a range of 250 miles on a single charge, and be able to charge in an hour or less at charging stations that could also be used for electric ground vehicles. They would have a cruising speed of up to 150 miles per hour, and produce zero emissions while operating.
As reported by Tesmanian: Tesla's decision to move Jerome Guillen to the Tesla Heavy Trucking position is a significant strategic move that demonstrates the company's offensive into the truck industry in the coming years, Wedbush said. The new announcement comes amid active efforts to bring the Tesla Semi to market, which will happen this year.
In a research note released on March 15, Wedbush analysts commented on the changes that have occurred in the appointments of Tesla's positions, which became known early Monday morning. Analysts Daniel Ives and Strecker Backe said that Tesla's decision to transfer Jerome Guillen, who until now was president of the Automotive unit, to its heavy trucking business is a "significant strategic" move to double down on the electric car maker's semi and trucking vision over the next few years.
Analysts wrote that Guillen played a critical role in Model 3's success and supply chain improvement in Fremont, USA, and Giga Shanghai, China. At this point, he has already changed his job title on Linkedin. Wedbush maintained a $950 price target and outperform rating on the stock.
The firm also commented on the new title of Tesla CEO Elon Musk. He chose to add "Technoking of Tesla" to his role, which hints that he sees the company as more as a technology disruptor, especially with robotaxis and battery technology advancements.
The simultaneous expansion of Zack Kirkhorn's CFO title to "Coin Master" could hint that Tesla owns bitcoin, which is expected to expand next year, analysts said.

As reported by Phys.org: A new quantum sensor can analyze the full spectrum of radio frequency and real-world signals, unleashing new potentials for soldier communications, spectrum awareness and electronic warfare.
Army researchers built the quantum sensor, which can sample the radio-frequency spectrum—from zero frequency up to 20 GHz—and detect AM and FM radio, Bluetooth, Wi-Fi and other communication signals.
The Rydberg sensor uses laser beams to create highly-excited Rydberg atoms directly above a microwave circuit, to boost and hone in on the portion of the spectrum being measured. The Rydberg atoms are sensitive to the circuit's voltage, enabling the device to be used as a sensitive probe for the wide range of signals in the RF spectrum.
"All previous demonstrations of Rydberg atomic sensors have only been able to sense small and specific regions of the RF spectrum, but our sensor now operates continuously over a wide frequency range for the first time," said Dr. Kevin Cox, a researcher at the U.S. Army Combat Capabilities Development Command, now known as DEVCOM, Army Research Laboratory. "This is a really important step toward proving that quantum sensors can provide a new, and dominant, set of capabilities for our Soldiers, who are operating in an increasingly complex electro-magnetic battlespace."
The Rydberg spectrum analyzer has the potential to surpass fundamental limitations of traditional electronics in sensitivity, bandwidth and frequency range. Because of this, the lab's Rydberg spectrum analyzer and other quantum sensors have the potential to unlock a new frontier of Army sensors for spectrum awareness, electronic warfare, sensing and communications—part of the Army's modernization strategy.
"Devices that are based on quantum constituents are one of the Army's top priorities to enable technical surprise in the competitive future battlespace," said Army researcher Dr. David Meyer. "Quantum sensors in general, including the one demonstrated here, offer unparalleled sensitivity and accuracy to detect a wide range of mission-critical signals."
The peer-reviewed journal Physical Review Applied published the researchers' findings, Waveguide-coupled Rydberg spectrum analyzer from 0 to 20 GigaHerz, co-authored by Army researchers Drs. David Meyer, Paul Kunz, and Kevin Cox

The researchers plan additional development to improve the signal sensitivity of the Rydberg spectrum analyzer, aiming to outperform existing state-of-the-art technology.
"Significant physics and engineering effort is still necessary before the Rydberg analyzer can integrate into a field-testable device," Cox said. "One of the first steps will be understanding how to retain and improve the device's performance as the sensor size is decreased. The Army has emerged as a leading developer of Rydberg sensors, and we expect more cutting-edge research to result as this futuristic technology concept quickly becomes a reality."
