NASA-Led Team Links Comet Water to Earth’s Oceans
Scientists find that cometary dust affects interpretation of spacecraft measurements, reopening the case for comets as potential sources of water for early Earth.
Amendment 74: A.63 Ecohydrology, a New Opportunity in ROSES-24
A.63 Ecohydrology is a special program element of the NASA Terrestrial Hydrology Program in recognition of the need for holistic, interdisciplinary approaches to evaluate and refine modeled coupled water, energy and carbon cycle process representation in a manner that more…
Final Venus Flyby for NASA’s Parker Solar Probe Queues Closest Sun Pass
On Wednesday, Nov. 6, 2024, NASA’s Parker Solar Probe will complete its final Venus gravity assist maneuver, passing within 233 miles (376 km) of Venus’ surface. The flyby will adjust Parker’s trajectory into its final orbital configuration, bringing the spacecraft…
Europa Trek: NASA Offers a New Guided Tour of Jupiter’s Ocean Moon
NASA Science Activation's Solar System Treks collaborated with Astrobiology SciComm Guild SMEs to create enhancements to the Europa Trek portal.
Old Data Yields New Secrets as NASA’s DAVINCI Preps for Venus Trip
How NASA's DAVINCI mission to Venus uses old data to reveal new secrets.
Priorities
Within NASA’s Science Mission Directorate (SMD), the Exploration Science and Strategy Office (ESSIO) leads NASA’s efforts to achieve our Moon to Mars (M2M) science objectives. These objectives are derived from Astrophysics, Planetary, Heliophysics, Earth, and Biological and Physical Sciences’ Decadal Surveys. For…
How NASA Uses and Improves Solar Power
How Solar Panels Work Silicon is an abundant material used in many technological applications because it is a very good “semiconductor,” or material whose ability to carry electric current can be easily manipulated by adding energy. In typical solar cells,…
Celebrating 10 Years at Mars with NASA’s MAVEN Mission
A decade ago, on Sept. 21, 2014, NASA’s MAVEN (Mars Atmospheric and Volatile EvolutioN) spacecraft entered orbit around Mars, beginning its ongoing exploration of the Red Planet’s upper atmosphere. The mission has produced a wealth of data about how Mars’…
NASA Discovers a Long-Sought Global Electric Field on Earth
An international team of scientists has successfully measured a planet-wide electric field thought to be as fundamental to Earth as its gravity and magnetic fields. Known as the ambipolar electric field, scientists first hypothesized over 60 years ago that it…
