Months in the Midnight Sun
Far above the Arctic Circle, the landscape around Utqiaġvik, Alaska, transforms from a frozen tundra to a mosaic of ponds during its 84 days without a sunset.
Autonomous Tritium Micropowered Sensors
Peter CabauyCity Labs, Inc. The NIAC Phase I study confirmed the feasibility of nuclear-micropowered probes (NMPs) using tritium betavoltaic power technology for autonomous exploration of the Moon’s permanently shadowed regions (PSRs). This work advanced the technology’s readiness level (TRL) from…
Addressing Key Challenges To Mapping Sub-cm Orbital Debris in LEO via Plasma Soliton Detection
Christine HartzellUniversity of Maryland, College Park The proposed investigation will address key technological challenges associated with a previously funded NIAC Phase I award titled “On-Orbit, Collision-Free Mapping of Small Orbital Debris”. Sub-cm orbital debris in LEO is not detectable or…
Breathing Beyond Earth: A Reliable Oxygen Production Architecture for Human Space Exploration
Alvaro Romero-CalvoGeorgia Tech Research Corporation The reliable and efficient operation of spacecraft life support systems is challenged in microgravity by the near absence of buoyancy. This impacts the electrolytic production of oxygen and hydrogen from water by forcing the adoption…
TFINER – Thin Film Isotope Nuclear Engine Rocket
James BickfordCharles Stark Draper Laboratory, Inc. The Thin-Film Nuclear Engine Rocket (TFINER) is a novel space propulsion technology that enables aggressive space exploration for missions that are impossible with existing approaches. The concept uses thin layers of energetic radioisotopes to…
Photophoretic Propulsion Enabling Mesosphere Exploration
Igor BargatinUniversity of Pennsylvania We propose to use the photophoretic levitation and propulsion mechanism to create no-moving-parts flying vehicles that can be used to explore Earth’s upper atmosphere. The photophoretic force arises when a solid is heated relative to the…
Mars Roundtrip Success Enabled by Integrated Cooling through Inductively Coupled LED Emission (MaRS ICICLE)
Aaswath Pattabhi RamanUniversity of California, Los Angeles Exploration of Mars has captivated the public in recent decades with high-profile robotic missions and the images they have acquired seeding our collective imagination. NASA is actively planning for human exploration of Mars…
Gravity Poppers: Hopping Probes for the Interior Mapping of Small Solar System Bodies
Benjamin HockmanNASA Jet Propulsion Laboratory The goal of this effort is to develop a robust and affordable mission architecture that enables the gravimetric density reconstruction of small body interiors to unprecedented precision. Our architecture relies on the novel concept of…
Johnson’s Paige Whittington Builds a Symphony of Simulations
What do music ensembles and human spaceflight have in common? They require the harmonization of different elements to create an inspiring opus. NASA’s Paige Whittington has experience with both. As a principal flutist for Purdue University’s Wind Ensemble, Whittington helped…
Summary of the 2024 SAGE III/ISS Meeting
Introduction The Stratospheric Aerosol and Gas Experiment (SAGE) III/International Space Station [SAGEIII/ISS] Science Team Meeting (STM) took place on October 22–23, 2024, in a hybrid format. Approximately 50 scientists attended in person at NASA’s Langley Research Center (LaRC) – see…
A Final Resting Place in the Philippines
Thousands of soldiers killed during World War II are interred at the Manila American Cemetery, the largest overseas U.S. military cemetery.
Waterlogged Lake Gregory
A network of brackish lakes and associated wetlands in northwestern Australia held more water than usual in October 2024 following an especially intense wet season.
A Cerrado Above It All
A perched patch of grasslands and savanna in Brazil acts as a sponge to recharge groundwater and feed natural hot springs.
An Impact Crater Hiding in Plain Sight
Much of the Goyder impact structure has eroded away, but there are remnants in Australia’s Northern Territory.
NASA Videographer Wins Top Award for Capturing Human Side of Science
Capturing the high-stakes work behind NASA’s Airborne Science Program takes more than just technical skill – it takes vision. At NASA’s Armstrong Flight Research Center in Edwards, California, videographer Jacob Shaw brings that vision to life, documenting missions with a…
