NASA Science

NASA Science seeks to discover the secrets of the universe, search for life elsewhere, and protect and improve life on Earth and in space.

A Hubble image of the circumstellar disk around Vega. The disk is perfectly circular, and at the center is a black spot blocking out the bright glow of a star. Closer to the center, the disk is white. Radial striations extend out from the center, giving a ripple effect to the disk like the end of a sausage casing. The outer edge of the circular disk is blue.

NISAR

Launching in 2025, NISAR will systematically map Earth and study changes to ice sheets, glaciers, and sea ice in fine detail, as climate change warms the air and ocean.

NASA Science is Delivering

NASA Science is delivering: every second of every day, of every week, of every year. 2024 is proving to be yet another year of exceptional scientific discovery and achievement. From soft landing back on the Moon a few months ago, to celebrating the Heliophysics Big Year and a Total Solar Eclipse in the contiguous United States, to receiving stunning imagery from James Webb, NASA Science is as busy as ever. Recently launched earth science missions are also providing us unprecedented views of our planet and incredible insight into the health of our oceans and atmosphere, and helping decision-makers improve lives on Earth and safeguard our future. And we are charting a new, sustainable path for Mars Sample Return.
 
Looking ahead, we have many exciting launches on the horizon. At NASA, we are fortunate that our science and exploration endeavors are inextricably linked and help us discover and innovate for the benefit of humanity. Together, we explore to advance scientific understanding. Ultimately, exploration enables science, and science enables exploration.
 
The NASA Science team is continuing to deliver for the benefit of all.
