Europa is one of 53 confirmed moons orbiting Jupiter. While slightly smaller than Earth’s moon, Europa primarily consists of silicate rock and is intriguing in that its crust consists of frozen water. Future missions under consideration to Europa would be enhanced by the ability to penetrate the... Read More

Relic radiation from the Big Bang—the Cosmic Microwave Background (CMB)—provides a Rosetta stone for deciphering the content, structure, and evolution of the early universe. Current theoretical understanding suggests that the universe underwent a rapid exponential expansion, called “inflation,” in... Read More

Chorus waves are a class of frequency-chirping, whistler-mode plasma waves that are routinely observed in Earth’s near-space environment. Chorus waves play a key role in various physical processes including the formation of the Earth’s Van Allen radiation belts, the pulsating aurora, and the... Read More

NASA is developing a new type of detector that will provide insight into the formation and structure of the universe. Many of the radiative and mechanical interactions that shape the interstellar medium of galaxies and drive galactic evolution (e.g., shock waves from stellar winds and jets,... Read More

An SMD-sponsored project successfully designed, fabricated, and tested a new application-specific integrated circuit (ASIC) intended to enable high-quality radio occultation (RO) weather observations using signals from the Global Navigation System Satellite (GNSS) constellations. RO measurements... Read More

Over the past four years, NASA’s Heatshield for Extreme Entry Environment Technology (HEEET) Project has been maturing a novel, three-dimensional, woven Thermal Protection System (TPS) technology for science missions recommended in the Planetary Science Decadal Survey. These missions—Venus probes... Read More

A team of NASA optics experts has built a picometer spatial metrology system that may enable a major Agency initiative—to locate and image Earth-like planets beyond the solar system and scrutinize their atmospheres for signs of life. Researchers at Goddard Space Flight Center (GSFC), in conjunction... Read More

In March 2016, NASA announced the selection of two proposals—both direct infusions of Earth Science Technology Office (ESTO) projects—under the third solicitation of the Earth Venture Instrument (EVI) program. Managed by the Earth System Science Pathfinder (ESSP) program, the EVI program targets... Read More

In 2016, NASA delivered three types of detectors developed for Ultraviolet (UV), Near UV (NUV), and Near Infrared (NIR) applications to several different projects involving on-sky observations. Development of these charge-coupled devices (CCDs) required several new processes formulated by NASA.... Read More

NASA is sponsoring a team developing a new type of payload to collect ionospheric plasma data at multiple points near a suborbital main payload. These low-resource, easily reproducible payloads—called Bobs—were developed for the NASA Isinglass auroral sounding rocket mission (conducted in February... Read More

An X-ray telescope is characterized by four parameters: angular resolution, effective area, mass, and production cost. Researchers at NASA GSFC have developed a new X-ray mirror technology that is expected to improve one or more of these parameters by at least an order of magnitude, compared to the... Read More
