New Study Updates NASA on Space-Based Solar Power
Space-based solar power offers tantalizing possibilities for sustainable energy – in the future, orbital collection systems could harvest energy in space, and beam it wirelessly back to Earth. These systems could serve remote locations across the planet to supplement the…
NASA Selects Crew for Next Simulated Mars Mission
Editor’s Note, Jan. 26, 2024: The crew roster for this HERA mission has been updated. NASA selected a crew of four volunteers to participate in a simulated journey to Mars inside a habitat at the agency’s Johnson Space Center in…
This US-Indian Satellite Will Monitor Earth’s Changing Frozen Regions
NISAR will study changes to ice sheets, glaciers, and sea ice in fine detail, as climate change warms the air and ocean.
This US-Indian Satellite Will Monitor Earth’s Changing Frozen Regions
NISAR will study changes to ice sheets, glaciers, and sea ice in fine detail, as climate change warms the air and ocean. NISAR, the soon-to-launch radar satellite from NASA and the Indian Space Research Organisation (ISRO), will measure some key…
NASA’s Webb Discovers Dusty ‘Cat’s Tail’ in Beta Pictoris System
Beta Pictoris, a young planetary system located just 63 light-years away, continues to intrigue scientists even after decades of in-depth study. It possesses the first dust disk imaged around another star — a disk of debris produced by collisions between…
Discovery Alert: Earth-sized Planet Has a ‘Lava Hemisphere’
In a system with two known planets, astronomers spotted something new: a small object transiting across the Sun-sized star. This turned out to be another planet: extra hot and Earth-sized.

Early Stage Innovations (ESI) 2023
Back to ESI Home Advancing Radiation-Hardened Photon Counting Sensor Technologies Advancements in Predicting Plume-Surface Interaction Environments During Propulsive Landings Advancing the Performance of Refrigeration Systems Based on the Elastocaloric Effect
Continuous Bending-mode Elastocaloric Composite Refrigeration System for Compact, Lightweight, High-Efficiency Cooling
ESI23 Miljkovic Quadchart Nenad Miljkovic University of Illinois at Urbana-Champaign Traditional elastocaloric refrigeration systems are based on uniaxial compression of the elastocaloric material which makes them highly constrained by actuator requirements, the physics of column buckling, and limited surface area…
Advancing Elastocaloric Refrigeration through Co-design of Materials and Systems
ESI23 Shamberger Quadchart Patrick Shamberger Texas A&M University Elastocaloric materials heat up or cool down when stress is applied to them or removed. The objective of this grant is to develop improved elastocaloric effect materials that are capable of performing…
Physics-based Modeling and Tool Development for the Characterization and Uncertainty Quantification of Crater Formation and Ejecta Dynamics due to Plume-surface Interaction
ESI23 Scarborough Quadchart David ScarboroughAuburn University Professor Scarborough will develop and implement tools to extract critical data from experimental measurements of plume surface interaction (PSI) to identify and classify dominant regimes, develop physics-based, semi-empirical models to predict the PSI phenomena,…
Integrating Data-Driven and Physics-Based Models for Plume-Surface Interaction Predictions
ESI23 Villafane Quadchart Laura VillafaneUniversity of Illinois at Urbana-Champaign Rocket engine exhaust during lunar landings can blow away a large amount of lunar regolith causing damage to nearby hardware and the landing spacecraft itself. The complex physics governing this behavior…
Advancing Radiation-Hardened CMOS Detectors for NASA Missions
ESI23 Figer Quadchart Donald Figer Rochester Institute of Technology The objective of this grant is to investigate methods to reduce and mitigate the effects of radiation damage on single-photon counting and photon number resolving optical imaging detectors. To accomplish this,…
Radiation hardness study of superconducting detectors and electronics
ESI23 Berggren Quadchart Karl Berggren Massachusetts Institute of Technology Superconducting nanowire single-photon detectors (SNSPDs) are a promising new ultra-sensitive and low-noise detectors for applications ranging from deep-space exploration to ultrafast space-based optical quantum communication networks. Their susceptibility to damage from…
Foggy Nile
A blanket of morning fog in January made the Nile Delta look like a tuft of cotton. Â
Advice from NASA Mentors to Students Starting Their Careers
NASA is celebrating National Mentoring Month by recognizing the importance of mentors to students and young professionals whose careers are beginning to take off. Mentors help their mentees gain real-world experiences, make valuable connections, and find the types of roles…
NASA Funds Laser Communications Tech with Small Business
Editor’s note, Jan. 16, 2024: This article has been updated to clarify that the Low-Cost Optical Terminal is a pre-production prototype ground station, which may be used for Orion Artemis II Optical Communications System demonstrations. NASA is working with private…
10 Years Ago: The First Operational Cygnus Cargo Mission to the Space Station
To replace the cargo and crew transportation services to and from the International Space Station following the retirement of the space shuttle in 2011, the United States developed a novel approach to procure those services from American commercial entities. On…
