NASA Chooses Lockheed Martin To Build Nuclear Mars Rocket
The spacecraft will use a reactor from BWX Technologies to travel to the red planet.
NASA and DARPA have chosen Lockheed Martin to build a spacecraft featuring a nuclear rocket engine. The project is known as the Demonstration Rocket for Agile Cislunar Operations (DRACO), and should be ready for trials by 2027, in the hope that it will eventually be used for missions to Mars.
The rocket will use Nuclear thermal propulsion (NTP), which has several advantages over conventional chemical-powered engines. Nuclear power is up to five times more efficient than rocket fuel, which means that future spacecraft will be able to travel significantly further with a larger payload.
“These more powerful and efficient nuclear thermal propulsion systems can provide faster transit times between destinations,” explained Kirk Shireman, VP of Lunar Exploration Campaigns for Lockheed Martin. “Reducing transit time is vital for human missions to Mars to limit a crew’s exposure to radiation”.
The NTP system will use a nuclear reactor to rapidly heat hydrogen propellant to very high temperatures. The gas is then funneled through the engine’s nozzle, creating thrust. “This nuclear thermal propulsion system is designed to be extremely safe and reliable, using High Assay Low Enriched Uranium (HALEU) fuel to rapidly heat a super-cold gas,” explained reactor developers BWX Technologies. “As the gas is heated, it expands quickly and creates thrust to move the spacecraft more efficiently than typical chemical combustion engines”.

To help alleviate concerns about radioactive leaks, NASA and DARPA will use a conventional rocket to take the new spacecraft out of Earth’s orbit before powering up the reactor after the ship has reached a safe distance.

Samsung Smart Glasses Teased For January, Software Reveal Imminent
According to Korean sources, the new wearable will launch alongside the Galaxy S25, with the accompanying software platform unveiled this December.
Samsung appears poised to introduce its highly anticipated smart glasses in January 2025, alongside the launch of the Galaxy S25. According to sources in Korea, the company will first reveal the accompanying software platform later this month.
As per a report from Yonhap News, Samsung’s unveiling strategy for the smart glasses echoes its approach with the Galaxy Ring earlier this year. The January showcase won’t constitute a full product launch but will likely feature teaser visuals at the Galaxy S25 event. A more detailed rollout could follow in subsequent months.
Just in: Samsung is set to unveil a prototype of its augmented reality (AR) glasses, currently in development, during the Galaxy S25 Unpacked event early next year, likely in the form of videos or images.
Additionally, prior to revealing the prototype, Samsung plans to introduce…

The Galaxy Ring, for example, debuted in January via a short presentation during Samsung’s Unpacked event. The full product unveiling came later at MWC in February, and the final release followed in July. Samsung seems to be adopting a similar phased approach with its smart glasses, which are expected to hit the market in the third quarter of 2025.
A Collaborative Software Effort
Samsung’s partnership with Google has played a key role in developing the smart glasses’ software. This collaboration was first announced in February 2023, with the device set to run on an Android-based platform. In July, the companies reiterated their plans to deliver an extended reality (XR) platform by the end of the year. The software specifics for the XR device are expected to be unveiled before the end of December.
Reports suggest that the smart glasses will resemble Ray-Ban Meta smart glasses in functionality. They won’t include a display but will weigh approximately 50 grams, emphasizing a lightweight, user-friendly design.
Feature Set And Compatibility
The glasses are rumored to integrate Google’s Gemini technology, alongside features like gesture recognition and potential payment capabilities. Samsung aims to create a seamless user experience by integrating the glasses with its broader Galaxy ecosystem, starting with the Galaxy S25, slated for release on January 22.
