NASA Reconnects with TRACERS Science Satellite
NASA announced a hopeful development for one of its small science missions: contact was re-established with one of the two TRACERS satellites, which had encountered communication failures after launch in July. According to NASA, mission operations regained contact with Space Vehicle 1 (SV1) and are “working to recover the spacecraft and establish science operations” science.nasa.gov. The twin TRACERS satellites (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) are designed to study Earth’s magnetosphere and the interactions of the solar wind, providing insight into space weather effects.
Engineers are now carefully checking SV1’s power, communications, and instruments to diagnose the glitch and resume the mission. “They have restored communication, but that does not make the craft operational,” a NASA update cautioned, noting that telemetry must be downloaded and systems verified before full science activities can resume gadgets360.com gadgets360.com. The recovery effort underscores NASA’s commitment to maximizing science return even after on-orbit anomalies. As one mission team member put it, regaining the link is a major step forward but work remains to ensure the satellite can fulfill its objectives gadgets360.com.
First Tranche 1 Military Satellites Deployed to Orbit
In a significant defense space milestone, the U.S. Space Force’s Space Development Agency (SDA) launched its first batch of “Tranche 1” satellites that will form part of a new orbital military data network. On Sept. 10, a SpaceX Falcon 9 from Vandenberg SFB delivered 21 Transport Layer satellites into low Earth orbit – “the first launch of Tranche 1” – carrying small York Space Systems-built payloads for communications and data relay copernical.com. These satellites are part of the Proliferated Warfighter Space Architecture (PWSA), a mesh network intended to provide low-latency, beyond-line-of-sight tactical links for U.S. and allied forces, including helping track advanced missile threats from LEO copernical.com copernical.com.
SDA’s acting director G.P. (Pete) Sandhoo hailed the launch as proof of the agency’s rapid-pace approach and a boost to warfighter capabilities. As the new constellation comes online, “it will enhance our strategic advantage by serving the joint warfighting force with operational capabilities previously thought infeasible from LEO,” Sandhoo said copernical.com. Tranche 1 is slated to deliver regional military coverage by 2027, including new Link-16 tactical data channels, missile warning/tracking sensors, and interoperable comms nodes, with 154 satellites planned in total across Transport and Tracking layers copernical.com copernical.com. To achieve this, SDA aims to continue launches at a pace of roughly one per month for the next nine months copernical.com. The successful “Tranche 1” kickoff demonstrates the Pentagon’s push to leverage commercial launch and satellite suppliers to field resilient space capabilities on fast timelines.
“Golden Dome” Space Shield Pegged at Trillions
A new independent analysis is raising eyebrows in Washington about the true price tag of an ambitious space-based missile defense plan. The concept, dubbed “Golden Dome for America,” envisions a multi-layered orbital shield against missiles and drones – but could cost anywhere from $252 billion up to a staggering $3.6 trillion over 20 years, according to a report released Sept. 12 by the American Enterprise Institute nationaldefensemagazine.org. That far exceeds the ~$175 billion figure previously mentioned by President Trump for this initiative nationaldefensemagazine.org.
Analyst Todd Harrison, the report’s author, outlined several notional architectures and found even the cheapest option (focused on limited drone/cruise missile defense) would run around $252 billion. A maximal “near-perfect” shield covering all threats could hit $3.6 trillion nationaldefensemagazine.org. Minor changes in scope – expanding coverage, countering more advanced threats, or adding redundancy – can alter costs “by hundreds of billions of dollars” due to the scale of space systems required nationaldefensemagazine.org. In short, Golden Dome’s price “hinges on the level of geographic coverage, the types and numbers of threats… and the degree of resilience,” the report notes nationaldefensemagazine.org.
The analysis bluntly contrasts current political promises with fiscal reality. Trump’s envisioned system at $175 billion would be “no match for the quantity of missiles China and Russia possess,” yielding results “far short of what the president promised, creating a multi-trillion-dollar gap between rhetoric and reality,” the report concludes nationaldefensemagazine.org. It emphasizes that achieving anything close to a true missile-proof nation would require budget choices on an historic scale. With only an initial $25 billion allotted to Golden Dome so far nationaldefensemagazine.org, the report suggests policymakers face tough decisions about the project’s scope and international partnerships going forward. In response, some defense experts propose scaling the vision to an allied “Golden Dome for NATO” to share costs and benefits, rather than the U.S. footing the whole bill alone starfightersspace.com.
Commercial Satellite Sector Warns of Budget Cuts
Commercial satellite companies are sounding the alarm that U.S. government budget uncertainty could stall the innovations and cost-savings they offer. Speaking at a recent industry forum, Susanne Hake – general manager for U.S. government business at Maxar – warned that cuts or delays in federal contracts pose a serious risk to the remote-sensing sector. Hake noted that the private industry has already demonstrated its worth by delivering imagery quickly and cheaply. “The industry has proven the value of commercial imagery,” she said, emphasizing that firms like Maxar “can deliver faster and for less cost than bespoke government satellites” – but only if they have predictable funding to justify ongoing investments spacelaunchschedule.com starfightersspace.com.
This isn’t a new plea: Maxar and others have for years urged agencies to make multi-year commitments (like the EnhancedView program that sustained commercial Earth imaging) instead of one-year procurements. Now, heightened budget pressures threaten programs that purchase commercial satellite data and services. Hake cautioned that if agencies pull back, it could undermine a key advantage the U.S. has in leveraging a dynamic private space sector. In her view, government customers should lean more into commercial solutions – which often deliver capability on orbit in a fraction of the time and cost of traditional programs – rather than retreat due to short-term fiscal tightening spacelaunchschedule.com.
Other industry leaders echoed that sentiment: stable demand signals and anchor tenancy by government can encourage companies to raise capital and accelerate innovation. Without it, critical providers might scale down future satellite constellations or shift focus to non-U.S. markets. The stakes extend to national security as well – commercially available high-resolution imagery and analytics have proven vital in recent global crises, from conflict zones to natural disasters. The message from industry is clear: don’t let short-sighted budget cuts jeopardize the thriving commercial space ecosystem that the government itself now heavily relies on spacelaunchschedule.com gadgets360.com.
China’s Mega Rocket Passes Key Engine Test
China’s lunar exploration program notched a major technological win as it pushes to land taikonauts on the Moon by 2030. On Sept. 12, Chinese engineers carried out a second successful static hot-fire test of the new Long March-10 rocket’s first stage – firing a cluster of seven YF-100K engines for a full 320 seconds with multiple restarts leonarddavid.com. The test, conducted at the Wenchang launch site in Hainan, validated the performance of the booster’s engines under both standard thrust and throttled restart conditions, yielding a wealth of data leonarddavid.com. China’s state media hailed the result, noting that all seven engines ignited and several were restarted as planned, demonstrating the stage’s robustness leonarddavid.com.
The Long March-10 (CZ-10) is a critical piece of China’s crewed lunar architecture. This heavy-lift, three-stage rocket – augmented by boosters – is designed to launch a crewed spacecraft and lunar lander on trans-lunar trajectories leonarddavid.com. (A related variant, Long March-10A, will be a partially reusable two-stage version for Earth-orbit missions like space station resupply leonarddavid.com.) In the first static test last month, the CZ-10’s engines achieved nearly 1,000 tons of thrust, the largest ever in China’s program leonarddavid.com.
By mastering clustered engine firings and restarts, China is tackling one of the biggest engineering hurdles for a Moon rocket. Chinese officials stated this latest test focused on the thermal and mechanical stresses of running seven engines simultaneously, and ensuring systems work in concert before the rocket’s flight debut leonarddavid.com. The success indicates the Long March-10 is on track, following other recent milestones like a pad abort test of the new Mengzhou crew capsule and a drop test of the Lanyue lunar lander earlier this year space.com space.com. As NASA’s Artemis program advances, China’s parallel Moon effort is clearly gathering momentum – underscoring the new international space race back to the lunar surface.
Congress Critiques Pentagon’s UFO Office
Unidentified Anomalous Phenomena (UAP) – the topic once known simply as UFOs – again took the spotlight on Capitol Hill. On Sept. 9, a House Oversight subcommittee held a high-profile hearing on UAP disclosure and grilled the Pentagon’s UAP investigative office (called AARO) for perceived lack of transparency space.com. Lawmakers and witnesses argued that military authorities continue to keep evidence of mysterious encounters under wraps, despite recent legislation pushing for more openness. Task force chair Rep. Anna Paulina Luna (R-FL) opened by rejecting any “sci-fi” stigma: “This is about national security, government accountability, and the American people’s right to the truth,” she said in her statement space.com. Luna and others stressed that credible reports of unexplained craft demand serious scrutiny, not secrecy or dismissal.
However, a striking point of contention emerged: Some witnesses criticized Congress itself for undermining scientific inquiry. Alejandro Rojas, a long-time UFO researcher and Enigma Labs consultant, observed that certain committee members seemed frustrated with AARO precisely because it was doing careful analysis. At the hearing, “the gripes of committee members came across as being frustrated with the organization that is using science and coming up with answers,” Rojas said space.com. Because these officials disliked the mundane explanations AARO has provided for many sightings, “they blame AARO, when in fact they genuinely do not want scientific analysis to dismantle their preconceived notions,” he commented pointedly space.com.
AARO’s director (Dr. Sean Kirkpatrick) was notably not invited to testify, leaving his office unable to rebut the accusations. In previous briefings, AARO has debunked several viral “UAP videos” by showing technical causes for odd visuals (like camera infrared quirks) space.com. This scientific approach has angered some UFO proponents, who accuse AARO of playing debunker rather than revealing exotic evidence. Rojas and other experts lamented that the hearing devolved into “political back-and-forth” instead of championing genuine science space.com. Harvard astronomer Avi Loeb weighed in that first-hand eyewitness accounts are “credible and intriguing,” but emphasized that only “scientific-quality data” will resolve what UAPs truly are space.com space.com.
The hearing did produce bipartisan calls for more whistleblower protections and declassification of UAP records. It also highlighted new amendments in the defense bill that would mandate disclosure of any government UFO materials. Veteran UFO investigators like Mark Rodeghier (Center for UFO Studies) praised the witnesses’ testimony and urged Congress to follow through by securing access to hidden evidence – possibly via closed-door sessions in classified facilities space.com space.com. The broader takeaway is that tension persists between those demanding total transparency on the UFO mystery and those insisting on scientific rigor and evidence. As one witness quipped, UAP phenomena are not a monolith – they likely span misidentified drones, secret tech, natural phenomena, and maybe a “small but stubborn residue” of the truly unexplained space.com. Cutting through decades of stigma and secrecy to figure out which is which will require both open minds and hard data – a balance that policymakers and the Pentagon are still struggling to strike.
