Are Nuclear Propulsion Systems the Future of Space Exploration?
Efforts are underway to develop advanced propulsion systems that can reduce transit times to Mars and other locations in the Solar System. These include nuclear propulsion concepts, which NASA began researching again in 2016 for its proposed "Moon to Mars" mission architecture. In a recent paper, two aerospace innovators reviewed some key nuclear-electric propulsion concepts, their respective advantages, and challenges. In the end, they conclude that nuclear propulsion has the potential to revolutionize space exploration and make humanity "multiplanetary."
How To Power CubeSats Using Deep Learning
Deciding how to power a CubeSat is one of the greatest challenges when designing a modular spacecraft. Tradeoffs in solar panel size, battery size, and power consumption levels are all key considerations when selecting parts and mission architecture. To help with those design choices, a paper from researchers in Ethiopia and Korea describes a new machine-learning algorithm that helps CubeSat designers optimize their power consumption, ensuring these little satellites have a better chance of fulfilling their purpose.

NASA Awards Launch Services Contract for SpaceX Starship
NASA has awarded SpaceX of Starbase, Texas, a modification under the NASA Launch Services (NLS) II contract to add Starship to their existing Falcon 9 and Falcon Heavy launch service offerings.
The NLS II contracts provide a broad range of commercial launch services for NASA’s planetary, Earth-observing, exploration, and scientific satellites. These high-priority, low and medium risk tolerant missions have full NASA technical oversight and mission assurance, resulting in the highest probability of launch success.
The NLS II contracts are multiple award, indefinite-delivery/indefinite-quantity, with an ordering period through June 2030 and an overall period of performance through December 2032. The contracts include an on-ramp provision that provides an opportunity annually for new launch service providers to add their launch service on an NLS II contract and compete for future missions and allows existing contractors to introduce launch services not currently on their NLS II contracts.
The contracts support the goals and objectives of the agency’s Science Mission Directorate, Space Operations Mission Directorate, Explorations Systems Development Mission Directorate, and the Space Technology Mission Directorate. Under the contracts, NASA also can provide launch services to other federal government agencies.
NASA’s Launch Services Program Office at the agency’s Kennedy Space Center in Florida manages the NLS II contracts. For more information about NASA and agency programs, visit:

NASA Boosts Efficiency with Custom X-66 Flooring

NASA designed temporary floorboards for the MD-90 aircraft to use while it is transformed into the X-66 experimental demonstrator aircraft. These floorboards will protect the original flooring and streamline the modification process.
Supporting the agency’s Sustainable Flight Demonstrator project, a small team in the Experimental Fabrication Shop at NASA’s Armstrong Flight Research Center in Edwards, California, built temporary floorboards to save the project time and resources. Repeated removal and installation of the original flooring during the modification process was time-consuming. Using temporary panels also ensures the original floorboards are protected and remain flightworthy for when modifications are complete, and the original flooring is reinstalled.
“The task of creating the temporary floorboards for the MD-90 involves a meticulous process aimed at facilitating modifications while maintaining safety and efficiency. The need for these temporary floorboards arises from the detailed procedure required to remove and reinstall the Original Equipment Manufacturer (OEM) floorboards,” said Jason Nelson, experimental fabrication lead. He is one of two members of the fabrication team – one engineering technician and one inspector – manufacturing about 50 temporary floorboards, which range in size from 20 inches by 36 inches to 42 inches by 75 inches.

Nelson continued, “Since these OEM boards will be removed and reinstalled multiple times to accommodate necessary modifications, the temporary floorboards will save the team valuable time and resources. They will also provide the same level of safety and strength as the OEM boards, ensuring that the process runs smoothly without compromising quality.”
Designing and prototyping the flooring was a meticulous process, but the temporary solution plays a crucial role in optimizing time and resources as NASA works to advance safe and efficient air travel. The agency’s Sustainable Flight Demonstrator project seeks to inform the next generation of single-aisle airliners, the most common aircraft in commercial aviation fleets around the world. NASA partnered with Boeing to develop the X-66 experimental demonstrator aircraft.

Its Mission Over, Gaia Rides Off Into the Sunset
No matter where on Earth you stand, if you have a view of the night sky, and if it is dark enough, you can see the Milky Way. The Milky Way is our home, and its faint clouds of light and shadow have inspired human cultures across the globe. And yet, our view of the Milky Way is limited by our perspective. In many ways, we have learned more from other galaxies than from our own. But when the Gaia spacecraft launched in 2013, all of that changed.
