NASA engineers have successfully revived Voyager 1's backup thrusters, unused since 2004 and once considered defunct. Space.com reports: This remarkable feat became necessary because the spacecraft's primary thrusters, which control its orientation, have been degrading due to residue buildup. If its thrusters fail completely, Voyager 1 could lose its ability to point its antenna toward Earth, therefore cutting off communication with Earth after nearly 50 years of operation. To make matters more urgent, the team faced a strict deadline while trying to remedy the thruster situation. After May 4, the Earth-based antenna that sends commands to Voyager 1 -- and its twin, Voyager 2 -- was scheduled to go offline for months of upgrades. This would have made timely intervention impossible. To solve the problem, NASA's team had to reactivate Voyager 1's long-dormant backup roll thrusters and then attempt to restart the heaters that keep them operational. If the star tracker drifted too far from its guide star during this process, the roll thrusters would automatically fire as a safety measure -- but if the heaters weren't back online by then, firing the thrusters could cause a dangerous pressure spike. So, the team had to precisely realign the star tracker before the thrusters engaged. Because Voyager is so incredibly distant, the team faced an agonizing 23-hour wait for the radio signal to travel all the way back to Earth. If the test had failed, Voyager might have already been in serious trouble. Then, on March 20, their patience was finally rewarded when Voyager responded perfectly to their commands. Within 20 minutes of receiving the signal, the team saw the thruster heaters' temperature soar -- a clear sign that the backup thrusters were firing as planned. "It was such a glorious moment. Team morale was very high that day," Todd Barber, the mission's propulsion lead at JPL, said in the statement. "These thrusters were considered dead. And that was a legitimate conclusion. It's just that one of our engineers had this insight that maybe there was this other possible cause, and it was fixable. It was yet another miracle save for Voyager."

An anonymous reader quotes a report from Ars Technica: Federal Communications Commission Chairman Brendan Carr has threatened to revoke EchoStar licenses for radio frequency bands coveted by rival firms including SpaceX, which alleges that EchoStar is underutilizing the spectrum. "I have directed agency staff to begin a review of EchoStar's compliance with its federal obligations to provide 5G service throughout the United States per the terms of its federal spectrum licenses," Carr wrote in a May 9 letter to EchoStar Chairman Charles Ergen. EchoStar and its affiliates "hold a large number of FCC spectrum licenses that cover a significant amount of spectrum," the letter said. Ergen defended his company's wireless deployment but informed investors that EchoStar "cannot predict with any degree of certainty the outcome" of the FCC proceedings. The letter from Carr and Ergen's statement is included in a Securities and Exchange Commission filing submitted by EchoStar today. EchoStar's stock price was down about 8 percent in trading today. EchoStar bought Dish Network in December 2023 and offers wireless service under the Boost Mobile brand. As The Wall Street Journal notes, the firm "has spent years wiring thousands of cellphone towers to help Boost become a wireless operator that could rival AT&T, Verizon and T-Mobile, but the project has been slow-going. Boost's subscriber base has shrunk in the five years since Ergen bought the brand from Sprint." [...] EchoStar will have to prove its case in the two FCC proceedings. The FCC set a May 27 deadline for the first round of comments in both proceedings and a June 6 deadline for reply comments. The proceedings could result in the FCC letting other companies use the spectrum and other remedies. "In particular, we seek information on whether EchoStar is utilizing the 2 GHz band for MSS consistent with the terms of its authorizations and the Commission's rules and policies governing the expectation of robust MSS," the FCC Space Bureau's call for comments said. "We also seek comment on steps the Commission might take to make more intensive use of the 2 GHz band, including but not limited to allowing new MSS entrants in the band." Last month, SpaceX urged the FCC to reallocate the spectrum, saying "the 2 GHz band remains ripe for sharing among next-generation satellite systems that seek to finally make productive use of the spectrum for consumers and first responders." EchoStar countered that SpaceX's filing is "intended to cloak another land grab for even more free spectrum," and that its "methodology is completely nonsensical, given that EchoStar's terrestrial deployment is subject to population-based milestones that EchoStar has repeatedly demonstrated in status reports."

Just days after a radar and communications outage at Newark Liberty International Airport, the FAA confirmed a second incident on May 9 that disrupted radar and radio contact for 90 seconds due to a telecom failure at Philadelphia TRACON. "As of 12:30PM ET, FlightAware stats showed 292 total delays for flights into or out of Newark, which is also experiencing delays due to runway construction," reports The Verge. From the report: After the first outage on April 28th, an air traffic controller who had been on duty that day told CNN it "...was the most dangerous situation you could have." CNN reports that after a change made last July, the airport's radar and radio communication flows over a single data feed from a facility in New York, where controllers used to manage Newark's flights, to Philadelphia. The FAA has announced a plan to replace the current copper connection with fiber, as well as adding "three new, high-bandwidth telecommunications connections between the New York-based STARS and the Philadelphia TRACON," and more air traffic controllers. Until those and other changes are made, the agency also said a new backup system is being deployed in Philadelphia, but it's unclear when that will be available. NBC News reports the Friday outage affected a limited number of sectors, but it's another incident in the string of issues that have highlighted the problems with the airport's aging control system and lack of staffing. [...] A statement from the FAA said, "Frequent equipment and telecommunications outages can be stressful for controllers. Some controllers at the Philadelphia TRACON who work Newark arrivals and departures have taken time off to recover from the stress of multiple recent outages."

schwit1 shares a report from Behind The Black: Almost immediately after India's government issued this week new tightened regulations for allowing private satellite constellations to sell their services in India, it also apparently completed negotiations with SpaceX to allow it to sell Starlink in India based on these rules. Business Today reports: "According to sources, the DoT [Department of Transportation] granted the LoI [Letter of Intent] after Starlink accepted 29 strict security conditions, including requirements for real-time terminal tracking, mandatory local data processing, legal interception capabilities, and localisation of at least 20% of its ground segment infrastructure within the first few years of operation. Starlink's nod came amid heightened national security sensitivities, coinciding with India's pre-dawn Operation Sindoor strikes on terror camps across the border in response to the Pahalgam massacre. However, DoT officials clarified that the decision to approve Starlink was independent of these military developments." At the moment SpaceX's chief competitors, OneWeb and Amazon's Kuiper constellation, have not yet obtained the same permissions. This allows SpaceX to grab a large portion of the market share in India before either of these other companies.

With iOS 18.5, Apple is bringing carrier-based satellite connectivity to the entire iPhone 13 lineup, allowing users with compatible carrier plans (like T-Mobile's Starlink-powered service) to access satellite features in areas without traditional coverage. The update is expected to launch next week. 9to5Mac reports: It's important to note that this update does not bring Apple's Emergency SOS via satellite to the iPhone 13 series. That feature relies on specialized hardware found only in iPhone 14 and later and functions independently of carrier networks. It also doesn't "install Starlink" on every iPhone, just support for carrier-provided satellite features like Starlink. By contrast, carrier-provided satellite services behave more like conventional cellular connections and require a participating plan to work.

The European Space Agency has launched the Biomass satellite to study the world's forests using the first space-based P-band synthetic aperture radar, aiming to accurately measure carbon storage and improve understanding of the global carbon cycle. CBS News reports: Forests on Earth collectively absorb and store about 8 billion tons of carbon dioxide annually, the ESA said. That regulates the planet's temperature. Deforestation and degradation, especially in tropical regions, means that stored carbon is being released back into the atmosphere, the ESA said, which can contribute to climate change. There's a lack of accurate data on how much carbon the planet's estimated 1.5 trillion trees store and how much human activity can impact that storage, the ESA said. To "weigh" the planet's trees and determine their carbon dioxide capacity, Biomass will use a P-band synthetic aperture radar. It's the first such piece of technology in space. The radar can penetrate forest canopies and measure woody biomass, including trunks, branches and stems, the ESA said. Most forest carbon is stored in these parts of the trees. Those measurements will act as a proxy for carbon storage, the ESA said. [...] Once the radar takes the measurements, the data will be received by the large mesh reflector. It will then be sent to the ESA's mission control center.

South Korean telecom network SK Telecom is providing free SIM card replacements to all 25 million mobile subscribers following an April 19 security breach where malware compromised Universal Subscriber Identity Module data. Despite the company's announcement, only 6 million replacement cards will be available through May 2025. The stolen data potentially includes IMSI numbers, authentication keys, and network usage information, though customer names, identification details, and financial information remain secure. The primary risk is unauthorized SIM swapping attacks, where threat actors could clone SIM cards.

Researchers in Germany successfully demonstrated coherent quantum communications over 254 km of existing commercial telecom fiber, marking the first real-world deployment of such a system without cryogenic cooling. Phys.Org reports: Their system uses a coherence-based twin-field quantum key distribution, which facilitates the distribution of secure information over long distances. The quantum communications network was deployed over three telecommunication data centers in Germany (Frankfurt, Kehl and Kirchfeld), connected by 254 km of commercial optical fiber -- a new record distance for real-world and practical quantum key distribution, according to the authors. This demonstration indicates that advanced quantum communications protocols that exploit the coherence of light can be made to work over existing telecom infrastructure. The research has been published in the journal Nature.

Amazon's internet-from-space venture is struggling to ramp up production, jeopardizing its ability to meet a government deadline to have more than 1,600 satellites in orbit by next summer. From a report: Project Kuiper has completed just a few dozen satellites so far, more than a year into its manufacturing program, according to three people familiar with the situation. The slow pace, combined with rocket launch delays, means the company will probably have to seek an extension from the Federal Communications Commission, said the people, who requested anonymity to discuss confidential matters. The agency, which has oversight of transmissions from space, expects the company to have half its planned constellation of 3,236 satellites operating by the end of July 2026. To meet that requirement, Amazon would have to at least quadruple the current rate of production, which has yet to consistently reach one satellite a day, two of the people said.

Indonesian migrant fishermen working in Taiwan's distant-water fishing fleet are trapped in brutal conditions that strip away basic human communication. Sailors spend up to 10 months at sea, working 22-hour days with no internet access, unable to contact families or report workplace hazards. A coalition of labor rights groups, 404 Media, is pushing to mandate Wi-Fi on ships, challenging an industry that intentionally isolates workers and prevents them from seeking help or organizing.

FCC Chairman Brendan Carr has issued a stark ultimatum to European allies, telling them to choose between US and Chinese communications technology. In an interview with Financial Times, Carr urged "allied western democracies" to "focus on the real long-term bogey: the rise of the Chinese Communist party." The warning comes as European governments question Starlink's reliability after Washington threatened to switch off its services in Ukraine. UK telecoms BT and Virgin Media O2 are currently trialing Starlink's satellite internet technology but haven't signed full agreements. "If you're concerned about Starlink, just wait for the CCP's version, then you'll be really worried," said Carr. Carr claimed Europe is "caught" between Washington and Beijing, with a "great divide" emerging between "CCP-aligned countries and others" in AI and satellite technology. He also accused the European Commission of "protectionism" and an "anti-American" attitude while suggesting Nokia and Ericsson should relocate manufacturing to the US to avoid Trump's import tariffs.

The European Space Agency's short film Space Debris: Is it a Crisis? highlights the growing danger of orbital clutter, warning that "70% of the 20,000 satellites ever launched remain in space today, orbiting alongside hundreds of millions of fragments left behind by collisions, explosions and intentional destruction." Inkl reports: The approximately eight-minute-long film "Space Debris: Is it a Crisis?" attempts to answer its conjecture with supportive statistics and orbital projections. [...] The film also mentions that the kind of Earth orbit matters when discussing whether we're in a space junk "crisis" -- though unfortunately, orbits at risk appear to be those with satellites that help with communication and navigation, as well as our fight against another primarily human-driven crisis: global warming. Still, the film emphasizes that solutions ought to be thought of carefully: "True sustainability is complex, and rushed solutions risk creating the problem of burden-shifting." You can watch the film on ESA's website.

Amazon and United Launch Alliance will launch 27 full-scale satellites on April 9 as part of Amazon's Project Kuiper, marking the company's first major step toward building a global satellite internet network to rival SpaceX's Starlink. GeekWire reports: ULA said the three-hour window for the Atlas V rocket's liftoff from Cape Canaveral Space Force Station's Space Launch Complex 41 in Florida is scheduled to open at noon ET (9 a.m. PT) that day. ULA is planning a live stream of launch coverage via its website starting about 20 minutes ahead of liftoff. Amazon said next week's mission -- known as Kuiper-1 or KA-1 (for Kuiper Atlas 1) -- will put 27 Kuiper satellites into orbit at an altitude of 280 miles (450 kilometers). ULA launched two prototype Kuiper satellites into orbit for testing in October 2023, but KA-1 will mark Amazon's first full-scale launch of a batch of operational satellites designed to bring high-speed internet access to millions of people around the world. [...] According to Amazon, the Kuiper satellite design has gone through significant upgrades since the prototypes were launched in 2023. Amazon's primary manufacturing facility is in Kirkland, Wash., with some of the components produced at Project Kuiper's headquarters in nearby Redmond. The mission profile for KA-1 calls for deploying the satellites safely in orbit and establishing ground-to-space contact. The satellites would then use their electric propulsion systems to settle into their assigned orbits at an altitude of 392 miles (630 kilometers), under the management of Project Kuiper's mission operations team in Redmond. Under the current terms of its license from the Federal Communications Commission, Amazon is due to launch 3,232 Kuiper satellites by 2029, with half of those satellites going into orbit by mid-2026.

An anonymous reader quotes a report from Politico: A top Commerce Department official sent a blistering email to his former colleagues on his way out the door Sunday warning that the Trump administration is poised to unduly enrich Elon Musk's satellite internet company with money for rural broadband. The technology offered by Starlink ... is inferior, wrote Evan Feinman, who had directed the $42.5 billion broadband program for the past three years. "Stranding all or part of rural America with worse internet so that we can make the world's richest man even richer is yet another in a long line of betrayals by Washington," Feinman said. Feinman's lengthy email, totaling more than 1,100 words and shared with POLITICO, is a sign of deep discomfort about the changes underway that will likely transform the Broadband Equity, Access and Deployment Program. Commerce Secretary Howard Lutnick recently pledged a vigorous review of BEAD, with an aim to rip out what he sees as extraneous requirements and remove any preference for particular broadband technologies like fiber. The program, created in the 2021 infrastructure law program, became a source of partisan fighting last year on the campaign trail as Republicans attacked the Biden administration for its slow pace. No internet expansion projects have begun using BEAD money, although some states were close at the beginning of this year. Feinman's critique: In his email, Feinman notes Friday was his last day leading BEAD and that he's "disappointed not to be able to see this project through." Feinman's email warns the Trump administration could undermine BEAD and he encourages people to fight to retain its best aspects. Feinman said the administration should "NOT change it to benefit technology that delivers slower speeds at higher costs to the household paying the bill," adding that this isn't what rural America, congressional Republicans or Democrats, the states or the telecom industry wants. "Reach out to your congressional delegation and reach out to the Trump Administration and tell them to strip out the needless requirements, but not to strip away from states the flexibility to get the best connections for their people," Feinman wrote. He said he's not worried about the Trump administration nixing requirements around climate resiliency, labor and middle class affordability, saying those issues "were inserted by the prior administration for messaging/political purposes, and were never central to the mission of the program." Feinman warns that changes to the BEAD program under the Trump administration could stall state-level broadband progress, with Louisiana, Delaware, and Nevada already stuck in review. Meanwhile, no specific guidance or timeline for these changes has been provided, and Arielle Roth's confirmation as NTIA head is still pending in the Senate.
