California high-speed rail could run out of money by December 2027, as authority cuts train order in halfThe watchdog's review warns the $4 billion federal funding loss now leaves the project needing billions in financing within 16 months — as the rail authority acknowledges for the first time that it still has no train contract, has cut its order from six trains to three, and has dropped the "Buy America" requirement.
Building the Moon Base: NASA Stories at the IonAs NASA prepares to return astronauts to the lunar surface for longer stays and increasingly complex operations, building the Moon Base will require new ideas, advanced technologies, and expertise across many fields. During NASA Stories at the Ion on July 30, Shatel Bhakta, principal systems engineer for NASA’s Moon Base Program, presented “Building the Moon Base: Challenges and Opportunities at the Lunar South Pole.” He discussed the work required to establish a sustained human […]
IRIS2 Gets Green Light With More Money and More SatellitesThe European Commission, ESA and the SpaceRISE consortium have completed a key review of Europe’s IRIS2 secure communications constellation, clearing the programme to move forward with full-scale implementation. The completion of the review was announced on 7 August following negotiations that began in January. The review was used to validate the programme’s costs, technical requirements […] The post IRIS2 Gets Green Light With More Money and More Satellites appeared first on European Spaceflight.
TB 26-04 Webbings for Use in Elevated Oxygen EnvironmentsFlammability test results for commercial-off-the-shelf webbings that meet NASA flammability requirements are reported for use in elevated oxygen environments anticipated for future lunar and Martian missions. Testing demonstrated that a webbing composed of 60% Kevlar®/40% polybenzimidazole (PBI) from Sturges Manufacturing Company, Inc., specifically the natural version, passed flammability testing per NASA-STD-6001B Test 1 using a […]

Robotically Assembled Electromagnetic Metamaterials for Long-Range Space Situational AwarenessDavid SmithDuke University The increasing population of spacefaring vehicles and satellites motivates increasingly powerful technologies for space situational awareness (SSA). While the US space surveillance network (SSN) is able to monitor objects down to about four inches in size using, for example, the latest upgrade to the space fence, the associated requirements limit implementation to ground-based […]
ECLIPSE – Efficient variable Conductivity Lunar Insulator for Passive Surveyor Environmental controlAustin Phoenix Virginia Polytechnic Institute & State A disaggregated lunar infrastructure requires novel thermal management methods to enable future lunar operations. While thermal management solutions exist for large infrastructure, the smaller mobile systems that operate independently require improved temperature regulation devices that can survive without heaters or substantial power requirements, while limiting stress-inducing temperature fluctuations. New […]
Show HN: Back up Claude Code sessions from Codespaces to a private repoI prefer to run Claude Code in GitHub Codespaces rather than on my local machine, but there is one problem: Claude Code logs disappear when the remote Codespace is deleted or rebuilt.Logkeeper saves a human-readable conversation log and an age-encrypted copy of the full JSONL to a designated private repository whenever a Claude Code session stops.After creating the private repository, adding the required Codespaces secrets, and adding a small set of hook and configuration files to the project, the backups run automatically.
Show HN: Postern, an email system for both humans and agentsHello everyone! I wanted to introduce you to a new project of mine, postern, which is an email system for both humans and agents. You can give your agents their own email addresses, the ability to respond to emails if you want, and all emails are presented in one nice unified mailbox. The email stack runs on Cloudflare Workers (email sending does require a subscription to the $5/mo Cloudflare Workers Plan), messages can be ingested into Vectorize (this is optional) to allow your agents to easily retrieve information and answer your questions about your email, attachments are stored in R2, and message state/contents are stored in D1. There’s also a RFC compliant SMTP relay server that runs on your server to translate anything that speaks the 1982 SMTP RFC spec into API calls so you can send emails from your server through the postern stack. There’s a python based IMAP proxy which allows you to use any client (tested extensively with iOS Mail, Apple Mail, Thunderbird, and Evolution) as w

NASA’s CAPSTONE Completes Extended Mission Testing Lunar TechnologiesAs NASA prepares for a sustained human presence on the Moon, missions will increasingly require spacecraft that can navigate and communicate without a direct connection to Earth. NASA’s Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment, or CAPSTONE, validated and advanced these capabilities. Designed to test and validate technologies in lunar orbit, CAPSTONE launched […]
NASA Seeks Industry Input to Accelerate Lunar Surface TechnologiesLong-term lunar exploration requires technology, infrastructure, and operations that function together cohesively on the surface of the Moon. To accelerate the development of key lunar surface systems and reduce risk, NASA and industry must work together in the design, development, testing, and evaluation of innovative solutions that support U.S. space priorities. NASA is seeking feedback on a draft solicitation for the Lunar […]
NASA Tests New Refuel Device for Future In-Space Refueling MissionsFor NASA’s next generation of deep space exploration missions, spacecraft may need to refuel in Earth orbit before pushing farther into the solar system. Similar to how a gas pump needs a nozzle to fit your fuel tank, future spacecraft could require a special device in order to fill up prior to departure, known as […]
Show HN: Write SaaS apps where users control where their data is storedHello HN,I would like to share with you linkedrecords.com - an open source backend as a service I'm working on since some time now. You can think of it as an firebase/convex alternative with an interesting twist.In 2018 I needed to write large software requirements/architecture documents in Google Docs. While I was annoyed by the limitations of Google Docs back then (no captions on figures, no automatic heading numbering, slow when docs are bigger,...) I was still fascinated by the real time collaboration features of it. So I've started a quest to understand how it works and I begun to implement an alternative to Google Docs.I was convinced that this kind of real time collaboration is the future so I've given it much thought how I could make this as generic as possible so I could use it in all future tools I would build.In the same time I was playing around with firebase (surprisingly you can not build a google docs alternative with firebase that easy as their real time collaboration d
Senate NDAA backs plan to fold SDA, Space RCO into Space ForceThe committee's 2027 defense bill would eliminate separate statutory requirements for the two acquisition organizations while advancing broader Pentagon procurement reforms The post Senate NDAA backs plan to fold SDA, Space RCO into Space Force appeared first on SpaceNews.
NASA Equips Astronauts, Industry with Robotic IntelligenceAs NASA plans long-term missions on the Moon, the agency could use robots to perform routine tasks, allowing crew members to dedicate more time to science and exploration. However, robotic motion control requires complex technology and advances in features like robotic decision-making and object recognition. These are the challenges a Boulder, Colorado-based robotics company is […]

The young minds space-proofing ESA’s missionsAssembling a spacecraft is a complicated process, and one that requires materials that are far from ordinary. To ensure the success of the European Space Agency’s missions, researchers in the Materials, Environments and Contamination Control Section investigate and test materials to ensure they will survive the harsh environment of space. The section is supported by many young researchers, who bring fresh and innovative ideas.
NASA Langley Engineer Attends FAA TrainingAt a busy airport, every aircraft in the area shares just a handful of radio frequencies. Spectrum and time are constrained and if multiple people speak at once, both messages can get lost. Communications like “clearance delivery,” which require long transmissions and readbacks, are challenging in high-traffic areas, particularly when weather or other factors require […]
