NASA tests an in-orbit refueling device for deep space missions — 2026-06-27

## Short Segments OpenAI's latest AI model, GPT-5.6, is now in limited preview, marking a strategic shift in AI deployment. The model, which includes three variants, is initially available to a select group of trusted partners. This move comes as the Trump administration has requested OpenAI to restrict the release to government-approved users. The preview includes access through API and Codex, with broader availability planned soon. This staggered release strategy highlights the growing intersection of AI development and regulatory oversight. As OpenAI navigates these constraints, the AI landscape continues to evolve with new models and capabilities. Elon Musk has received the green light from the FTC to acquire Mesh Optical Technologies, a startup founded by former SpaceX engineers. This acquisition is part of Musk's broader strategy to enhance data center communications with advanced optical hardware. Mesh specializes in optical transceivers that improve energy efficiency and reduce latency in AI data centers. The FTC's expedited review reflects the strategic importance of this technology in Musk's expanding portfolio. As Musk integrates Mesh's capabilities, the acquisition could reshape data center infrastructure and performance. Anthropic has regained permission from the US government to redeploy its Mythos cybersecurity AI model. This decision follows a temporary suspension due to national security concerns. Mythos 5 will now be available to select US organizations that manage critical infrastructure. The government's partial reversal of export restrictions underscores the delicate balance between AI innovation and security. As Anthropic resumes operations, the focus will be on ensuring that Mythos enhances cybersecurity without compromising national interests. ## Feature Story NASA is testing a groundbreaking in-orbit refueling device, the cryocoupler, which could revolutionize deep space missions. Developed by L3Harris, this technology aims to enable spacecraft to refuel in Earth's orbit before venturing further into the solar system. The cryocoupler functions like a gas pump nozzle, allowing spacecraft to connect to orbital propellant depots, essentially creating gas stations in space. This capability is crucial for long-term exploration missions, reducing the need for spacecraft to carry all their fuel from Earth. The testing is part of NASA's Liquid Oxygen Flight Demonstration, or LOXSAT, which will launch later this year. This mission will test 11 cryogenic fluid management technologies necessary for maintaining super-cold propellants in microgravity. The stakes are high, as successful demonstration could pave the way for sustainable lunar and Martian exploration. By enabling in-space refueling, NASA aims to extend the reach and duration of human and robotic missions beyond Earth's orbit. As NASA collaborates with Eta Space and other partners, the focus is on overcoming the challenges of storing and transferring cryogenic fuels in space. The cryocoupler's success could lead to the establishment of a network of orbital refueling stations, fundamentally changing how missions are planned and executed. This development not only enhances mission flexibility but also reduces costs and increases the potential for scientific discovery. As the LOXSAT mission progresses, the space community will be watching closely to see how this technology shapes the future of space exploration.
