SpaceX is seeking permission to launch another 30,000 low-Earth orbit (LEO) satellites for its Starlink broadband network, which would be in addition to the nearly 12,000 satellites the company already has permission to launch. But it's too early in the process to determine whether SpaceX is likely to launch most or all of the additional 30,000 satellites. Ars Technica reports: The Federal Communications Commission made the requests on SpaceX's behalf, as is standard practice, in a series of filings with the International Telecommunication Union (ITU) last week. (Here's an example of one of the filings.) The 30,000 satellites would operate "at altitudes ranging from 328 kilometers to 580 kilometers," SpaceNews reported yesterday. The filings are known as coordination requests. As SpaceNews noted, the ITU coordinates spectrum "to prevent signal interference and spectrum hogging." SpaceX's filings could help the company reserve spectrum before other operators claim it, but it's an early step in the process and doesn't commit SpaceX to launching all 30,000 satellites.

SpaceX's constellation alone would dwarf the total number of satellites orbiting Earth today. As of January 2019, about 8,950 satellites had been placed into Earth orbit since 1957, and about 5,000 of those were still in space, according to the European Space Agency (ESA). Only about 1,950 of those are still functioning. If SpaceX proceeds with the additional 30,000 satellites, it would have to seek FCC permission and provide more technical detail, including plans to minimize debris and prevent collisions. SpaceX is designing its satellites to burn up completely during atmospheric re-entry in order to prevent physical harm from falling objects.

SpaceX launched its sub-scale Starship 'hopper' spacecraft on a brief unpiloted up-and-down test flight at the company's Boca Chica, Texas, test facility Tuesday, a dramatic demonstration of rocket technology intended to pave the way to a new, more powerful heavy lift booster and, eventually, crew-carrying interplanetary spacecraft. Spaceflight Now reports: Running a day late because of a last-second technical glitch, the squat Starhopper's powerful methane-fueled Raptor engine thundered to life at 6:02 p.m. EDT, pushing the stubby test vehicle straight up into a clear blue sky atop a jet of flame and a churning cloud of exhaust. The spacecraft, shaped a bit like R2-D2 from the "Star Wars" movies, appeared to reach its FAA-approved 492-foot (150 meter) altitude limit, moved sideways and slowly descended to touchdown on a nearby landing pad. The approximately one-minute flight was the rocket's second "untethered" test following a July jump to an altitude of about 65 feet.

The hardware SpaceX is testing is intended for a fully reusable two-stage vehicle featuring a powerful first stage, dubbed the Super Heavy Rocket, and the winged Starship. The hopper is a sub-scale version of the Starship's propulsion system, the first to utilize a SpaceX-designed Raptor engine burning cryogenic methane with liquid oxygen. SpaceX says the new booster-Starship system eventually will replace the company's Falcon 9 and Falcon Heavy rockets as well as the Cargo and Crew Dragon capsules used to deliver supplies and, eventually, astronauts to the International Space Station. In other SpaceX news, the company's Dragon supply ship successfully departed the ISS and returned to Earth Tuesday to conclude its third round-trip flight to the orbiting research outpost, bringing home a spacesuit, mice and numerous experiments.

Shortly after the 2019 Hyperloop Pod competition ended, Elon Musk announced on Twitter that next year's Hyperloop competition will be held in a six mile curved vacuum tunnel. Previously, the competition was held in a straight three-quarters of a mile test tunnel which is located at SpaceX's headquarters in Hawthorne, California. Engadget reports: The Hyperloop competition is a student engineering challenge where teams are invited to design and build a prototype vehicle to travel in the potential Hyperloop network. The vehicles must be self-propelled and achieve maximum possible speeds without crashing. At this year's competition, in which a team from Technical University of Munich (TUM) reached a top speed of 288 miles per hour before damage occurred and an emergency stop had to be performed, Musk mentioned the possibility of expanding the competition to include tunneling as well.

"We'll consider a tunneling competition," Musk said at a Q&A about the competition, TechCrunch reports. "I think a tunneling thing would be pretty exciting. Because as I just articulated the primary challenge is how do you tunnel effectively, especially how do you put in the reinforcing segments and get the dirt out effectively -- it's harder than it seems."

SpaceX's fifth Falcon 9 rocket of the year successfully launched from Cape Canaveral this evening, sending 60 internet-beaming satellites into space. Space.com reports: Following the successful launch, the rocket's first stage gently touched down on a floating platform at sea, marking the company's 40th booster recovery. It was the third flight for this particular booster, marking just the second time SpaceX has flown a Falcon 9 first stage more than twice. The third time was a charm for SpaceX as the Falcon 9 lifted off at 10:30 p.m. EDT (0230 GMT on May 24) from Space Launch Complex 40 at Florida's Cape Canaveral Air Force Station here, following several delays: first a 24-hour delay due to high upper-level winds on May 15, and then a weeklong delay so SpaceX could give the onboard satellites a software software upgrade. Tucked inside the rocket's nose cone were 60 satellites -- the first batch of SpaceX's Starlink megaconstellation, which the company hopes will help provide affordable internet coverage to the world. Each of the Starlink satellites weighs 500 lbs. (227 kg). The 60-spacecraft haul is the heaviest payload that a Falcon 9 has yet hoisted to orbit, SpaceX representatives have said. The aerospace company plans to launch nearly 12,000 of these satellites in total, "which will park themselves in low-Earth orbit and beam internet coverage to the world below," the report says. "There will be two Starlink flocks: one constellation of 4,409 satellites and a second constellation of 7,518 satellites, according to an agreement with the FCC."

The one caveat is that the FCC approvals require SpaceX to launch half of the planned satellites within the next six years.

Valve's Steam Link app, which brings streaming games to your mobile device, is now available as a free download for iOS and Apple TV. The iOS launch comes nearly one year after Apple rejected the app due to "business conflicts." GameSpot reports: The Steam Link app promises to bring "desktop gaming to your iPhone or iPad." Users can pair a Steam controller or any MFI (Made-for-iPhone/iPad) controller to play games over a network connection provided they are on the same local network. The Steam Link app is effectively a replacement for the physical Steam Link device that Steam discontinued in 2018. Steam Link is already available on Android. As the Verge notes in their report, the biggest difference between the iOS and Android versions is that the iOS Steam Link app "doesn't allow users to purchase games from the Steam store, unlike on Android."

You can download Steam Link from iTunes here.

Blue Origin successfully performed another test launch of its New Shepard system today. Both the New Shepard rocket and capsule touched down safely back at the company's West Texas facility around 10 minutes after liftoff. The capsule reached about 346,000 feet, or more than 65 miles, eclipsing the recognized boundary of space. Some context: Before today, New Shepard has landed nine out of the 10 times it's flown, and the vehicle has proven that it can keep people safe even in emergency scenarios. However, there still isn't a solid timeline for when the first test passengers will fly on the vehicle, and the company has not started selling tickets to customers yet. The rocket flying this week is the third iteration of the New Shepard vehicle, and the company has built a fourth version that will take the first crews to space. That rocket is supposed to fly sometime this year, according to Blue Origin, but exactly when is still unclear.

An anonymous reader quotes a report from The Verge: SpaceX successfully landed the center core of its Falcon Heavy rocket on a drone ship last week, but the vehicle accidentally fell into the ocean while in transit to the Florida coast. The company blamed the loss on choppy seas. "Over the weekend, due to rough sea conditions, SpaceX's recovery team was unable to secure the center core booster for its return trip to Port Canaveral," SpaceX said in a statement to The Verge. "As conditions worsened with eight to ten foot swells, the booster began to shift and ultimately was unable to remain upright. While we had hoped to bring the booster back intact, the safety of our team always takes precedence. We do not expect future missions to be impacted."

SpaceX does have ways to secure the rockets it lands in the ocean, including a robot known as the "octagrabber" that latches on to the base of the boosters. But because the center core connects to two side boosters, it has a different design than a normal Falcon 9 booster. So the octagrabber cannot hold on to it in the same way. The center core is a modified Falcon 9 booster -- one of three that make up the Falcon Heavy rocket -- which flew last week during the second flight of the Falcon Heavy. "Following takeoff, all three cores of the rocket successfully landed back on Earth: the two outer cores touched down on dual concrete landing pads at the Cape while the center core touched down on the company's drone ship named Of Course I Still Love You in the Atlantic," reports The Verge.

Tesla and Panasonic are reportedly freezing their plans to add more battery production lines at Gigafactory 1, its massive factory outside of Reno, Nevada that is a cornerstone to the automaker's business. "The partners had planned to increase capacity by 50 percent next year, but financial problems have forced a rethink," reports TechCrunch, citing a report from Nikkei. "Nikkei also reported that Panasonic was suspending a planned investment in Tesla's automotive battery and EV plant in Shanghai." From the report: TechCrunch confirmed that Tesla is not adding more battery production lines and will instead focus its efforts on existing equipment. Tesla stressed that it will continue to make new investments as needed into the plant. However, the automaker noted that attention and investments might be focused on improving existing equipment to increase battery cell output.

As of November, Panasonic had 11 production lines operating at Gigafactory 1. Panasonic president President Kazuhiro Tsuga told Bloomberg that the company planned to add two more lines by the end of the year to bring total capacity up to 35 gigawatt-hours. The last number shared by Tesla is from July when the company reported an annualized run rate of 20 gigawatt-hours of capacity. It's not clear if those two production lines were added. "We will of course continue to make new investments in Gigafactory 1, as needed. However, we think there is far more output to be gained from improving existing production equipment than was previously estimated," a Tesla spokesperson wrote in an emailed statement.

MDMurphy writes: While people have good and bad things to say about Tesla, one consistent thing has been that the cars emit zero emissions when operating. But in Europe, in exchange for cash, Tesla is merging its fleet with that of Fiat Chrysler Automobiles (FCA). The amount FCA is paying Tesla is presumably less than they would in fines if they were on their own. With this merging of the fleets, in Europe at least, a Tesla is no more clean than a diesel Fiat. "The Italian-American carmaker is behind on meeting the new standard, and the so-called open pool option available at the EU allows automakers to group their fleets together to meet the targets," reports Bloomberg. "Payments to Tesla, whose electric cars don't produce CO2 emissions, may amount to over 500 million euros, according to Jefferies."

Ars Technica reports on the strict new EU regulations: "From 2020, 95 percent of an automaker's new cars sold in the EU have to meet this target, with the remaining 5 percent falling under the law in 2021. And the penalties for failing are draconian: a $107 'excess emissions premium' per gram of CO2 over the target, for every single car registered in the EU that year. For some OEMs, this has the potential to be ruinous; if FCA's portfolio were the same in 2021 as it was in 2018, the automaker would have to pay some $3.12 billion, out of total net global profits of $4.1 billion."

Yesterday Billboard magazine reported that Elon Musk had dropped a rap song on SoundCloud -- an auto-tuned song called "RIP Harambe." Posted under the handle Emo G Records, the two-minute track pays tribute to the Cincinnati Zoo gorilla who was killed in 2016 after a 3-year-old climbed into its living area. It's unclear if Musk stumbled upon the track, which has his name on it, or if he released the track himself...

"RIP Harambe" had more than 200,000 plays as of Sunday afternoon.
Some Twitter users left bemused replies, like "Dude, sober up by Thursday's contempt hearing." But the song appears to be part of a longer series of tweets. An anonymous reader writes: On Friday Musk had shared a blank tweet containing nothing but an emoji of a duck with his 25.5 million followers. It drew over 24,000 re-tweets, and 4,300 comments -- far more than the Harambe song (which drew only 14,000 retweets and 1,600 comments.) "Duck emoji FTW," Musk tweeted triumphantly on Sunday, following up on his earlier observation that "Duck emoji defeats Emo G Records. Crushing victory."
In its comments there was also a joke about X.com (the original online banking site Musk launched in 1999, which was eventually merged into PayPal). In 2017 Musk repurchased the domain because "it has great sentimental value" -- but replaced it with an entirely blank page with one lowercase x. In response to the duck emoji, someone tweeted that next Musk needed to update X.com.

Musk promptly replied by tweeting the URL x.com/x -- which (due to the site's error-handling) pulls up a web page with a single lowercase y.

One and a half years after announcing a wireless charging mat for iPhones, Apple Watches, and AirPods called AirPower, Apple has unexpectedly cancelled the accessory. From a report: It notably missed its expected shipping dates multiple times, including a potential release alongside the second-generation version of AirPods and charging case this week. "After much effort, we've concluded AirPower will not achieve our high standards and we have cancelled the project," said Apple SVP of Hardware Engineering Dan Riccio in a statement today. "We apologize to those customers who were looking forward to this launch. We continue to believe that the future is wireless and are committed to push the wireless experience forward." Mark Gurman of Bloomberg, adds, "This is fairly unprecedented and unbelievable. The AirPods even have a picture of the AirPower on the box."

An anonymous reader quotes a report from Ars Technica: According to Wired, glass-maker Corning is "working on ultrathin, bendable glass that's 0.1 millimeters thick and can bend to a 5 millimeter radius" that may be usable for smartphone displays within two years. Corning produces Gorilla Glass used in Apple's iPhones, as well as in phones made by other manufacturers like LG, Asus, OnePlus, Nokia, Samsung, and more. Developing Gorilla Glass that can bend or fold like the materials used for the Samsung Galaxy Fold display or other foldable phone concepts could address some shortcomings endemic to these early designs.

The folding phones you see in headlines and gadget blog galleries today rely on plastic polymers that may scratch easier or have other undesirable properties. Generally, smartphone-makers that have announced foldable phones have not allowed us to test-drive these phones, which is otherwise normal practice for traditional smartphone product unveilings. That may be primarily because the software is not there yet, but it could also be that the companies anticipate negative reactions to the plastic displays, which have not been standard in flagship phones for a decade. [...] John Bayne, Corning's head of Gorilla Glass, and another expert Wired spoke with believe that Corning (or a competitor like ACG) will have foldable glass ready for use in foldable smartphones within a couple of years. But it's a difficult journey. "We have glasses we've sampled to customers, and they're functional," Bayne told Wired. "But they're not quite meeting all the requirements. People either want better performance against a drop event or a tighter bend radius. We can give them one or the other; the key is to give them both."

"For anyone who thought that there was too much Tesla news this weekend, I've got some bad news for you," writes long-time Slashdot reader Rei, sharing new information gleaned from a series of tweets.

"Elon Musk just announced the unveiling of the Model Y SUV on March 14th at Tesla's LA Design Studio." A surprising number of details were revealed, including non-falcon doors, a similar appearance to the Model 3, and pricing about 10% more than a Model 3, with slightly lower range, due to the increased mass and cross section.

The unveiling will not include the Tesla pickup truck; that will be later this year. Model Y is to share 75% of its hardware with Model 3 to simplify the development process, with volume production targeted for late 2020, and initial production in early 2020. Musk also stated: "First public Tesla V3.0 Supercharger Station goes live Wed 8pm" (V3 is the much awaited new generation of higher power, cheaper to operate Superchargers).
"Personally, I'm most excited by the Tesla Truck," Musk posted on Twitter. "Maybe it will be too futuristic for most people, but I love it."
