NASA Ships Moon Rocket Stage Ahead of First Crewed Artemis Flight
==========
NASA has shipped the Space Launch System (SLS) rocket's core stage for the Artemis II test flight from its manufacturing facility in New Orleans to NASA's Kennedy Space Center in Florida. The core stage, which is the largest NASA has ever produced, consists of five major elements and will be integrated with other parts of the rocket for the Artemis II mission. The stage will operate for just over eight minutes, producing more than 2 million pounds of thrust to propel four astronauts inside NASA's Orion spacecraft toward the Moon. The SLS is part of NASA's Artemis campaign, which aims to land the first woman, first person of color, and the first international partner astronaut on the Moon.

NASA Awards Advance Technologies for Future Habitable Worlds Mission
==========
NASA has selected three industry proposals to develop technologies for future large space telescopes and plan for the agency's Habitable Worlds Observatory mission concept. The mission aims to directly image Earth-like planets around stars and study their atmospheres for signs of life. NASA is in the early planning stages for the mission and is establishing a Habitable Worlds Observatory Technology Maturation project office. The selected proposals will focus on high-fidelity modeling, subsystem demonstrations, integrated modeling infrastructure, and maturing technologies to support telescope features. The contracts have a combined value of $17.5 million and are targeted to begin by late summer 2024.

1942: Engine Roars to Life in First Test at Future NASA Glenn
==========
On May 8, 1942, the National Advisory Committee for Aeronautics (NACA) conducted its first test at the Aircraft Engine Research Laboratory, which is now NASA's Glenn Research Center. The test took place at the Engine Propeller Research Building (EPRB) and involved the activation of a massive piston engine. The EPRB was built to study full-scale piston engines and was constructed to muffle engine noise. The test was a significant milestone for the United States during World War II, as the military needed the laboratory to improve engine cooling, turbo-supercharging, and fuels for its aircraft. The completion of the laboratory was prioritized, and additional funding and supplies were allocated to meet the deadlines. Over the following year, more facilities were completed, and the NACA met its original deadlines. The official dedication of the new laboratory took place on May 20, 1943.

ScienceCraft for Outer Planet Exploration (SCOPE)
==========
NASA is developing a mission architecture called ScienceCraft for outer planet exploration. The mission aims to explore the ice giants Neptune and Uranus, which hold secrets about the formation and evolution of our solar system. ScienceCraft integrates a science instrument and spacecraft into one monolithic and lightweight structure by printing an ultra-lightweight quantum dot-based spectrometer directly on the solar sail. This breakthrough spacecraft architecture allows for unprecedented parallelism and throughput of data collection, as well as rapid travel across the solar system. The mission concept proposed for Triton, a unique planetary body in our solar system, aims to answer compelling science questions about Triton's atmosphere, ionosphere, plumes, and internal structure. The mission would be implemented by 2045. NASA plans to further mature the mission concept, develop key technologies, and address challenges in Phase II of the project.

Flexible Levitation on a Track (FLOAT)
==========
NASA is proposing to develop the Flexible Levitation on a Track (FLOAT) system, which is a lunar railway system that will provide reliable, autonomous, and efficient payload transport on the Moon. The FLOAT system employs unpowered magnetic robots that levitate over a 3-layer flexible film track. The robots can passively float over tracks using diamagnetic levitation and generate electromagnetic thrust to propel themselves along the tracks. The system will be able to transport regolith mined for ISRU consumables or construction, as well as payloads around the lunar base and to/from landing zones or other outposts. FLOAT tracks can be unrolled directly onto the lunar regolith and individual robots will be able to transport payloads of varying shape/size at useful speeds. A large-scale FLOAT system will be capable of moving up to 100,000s kg of regolith/payload multiple kilometers per day. The system will operate autonomously in the lunar environment with minimal site preparation, and its network of tracks can be rolled-up/reconfigured over time to match evolving lunar base mission requirements. In Phase 2, NASA will continue to retire risks related to the manufacture, deployment, control, and long-term operation of meter-scale robots/km-scale tracks that support human exploration activities on the Moon.

Radioisotope Thermoradiative Cell Power Generator
==========
The Radioisotope Thermoradiative Cell (TRC) is a revolutionary power source being developed by NASA. It operates like a solar cell in reverse, converting heat from a radioisotope source into infrared light, which generates electricity. In a Phase I study, 8 W of electrical power was generated from a 62.5 W Pu-238 pellet using a 0.28 eV bandgap TRC operating at 600 K. The necessary TRC array includes 1,125 cm² of emitters, with a mass specific power of 12.7 W/kg. By using low-bandgap III-V materials such as InAsSb in nanostructured arrays, a 25x improvement in mass specific power and a four order of magnitude decrease in volume from a multi-mission radioisotope thermoelectric generator (MMRTG) is possible. TRC technology will enable small versatile spacecraft with power requirements not met by photovoltaic arrays or MMRTG systems, allowing for missions to the outer planets and operations in permanent shadow areas. The project will investigate the thermodynamics and feasibility of the TRC power source, grow materials and TRC devices, test their performance, and develop an engineering design study for a cubesat mission operating at Uranus.

NASA Astronomer Sees Power in Community, Works to Build More
==========
Dr. Natasha Batalha, an astronomer at NASA’s Ames Research Center, collaborates with her teams to study exoplanets using NASA’s James Webb Space Telescope. Her work explores hot, Jupiter-like exoplanets, smaller rocky exoplanets, and brown dwarfs. Batalha is driven by the question of whether life exists beyond Earth and believes in the power of community to solve this question. She was inspired by her parents, who are also scientists, to pursue a career in astronomy. Batalha builds open-source tools to help scientists interpret data from Webb and is part of a team that detected sulfur dioxide in the atmosphere of exoplanet WASP-39 b. She believes in empowering her science community and passing on the baton to future generations in the search for life beyond Earth.
