It's not often that we get a chance to see our planet's shadow, but a lunar eclipse gives us a fleeting glimpse. During these rare events, the full Moon rapidly darkens and then glows red as it enters the Earth's shadow. Though a...

As a vital information pipeline for space-based research and exploration ambitions, the TDRS constellation fulfills NASA's broadest communication demands. Now into it's fourth operational decade, the TDRS legacy continues to be...

Seventy-five years ago, astronomer Lyman Spitzer envisioned a future for space exploration that deepened humanity’s curiosity about the cosmos. A visionary behind the Hubble Space Telescope, Spitzer was among the...

This video provides an overview of the structure of our solar system and how gravity plays a crucial role in maintaining this structure. The video begins with the description of the sun at the center of our solar system, and then it...

China has deployed a relay satellite that's meant to bridge communication between Earth and a planned exploration on the far side of the moon, Xinhua News Agency reports.

Retired NASA astronaut John Grunsfeld hosts this six-part mini-series about the tools used on the Hubble Space Telescope servicing missions. Hubble was uniquely designed to be serviced in space so that components could be...

On Jan. 31 att 10:48 p.m. EST, Explorer 1 launched into space, hurtling into Earth's orbit in seven and a half minutes. The next day's front-page news declared that the United States was now officially in the Space Age. Music:...

NASA's Transiting Exoplanet Survey Satellite (TESS) has discovered 21 planets outside our solar system and captured data on other interesting events occurring in the southern sky during its first year of...

NASA's Transiting Exoplanet Survey Satellite - TESS - will fly in an orbit that completes two circuits around Earth every time the Moon orbits once. This special orbit will allow TESS’s cameras to monitor each patch of sky...

NASA is sending the OSIRIS-REx spacecraft to explore near-Earth asteroid Bennu, a carbon-rich body that may contain clues to the origins of life. When OSIRIS-REx arrives at Bennu in 2018, it will spend over a year orbiting...

Measurements from NASAs Transiting Exoplanet Survey Satellite (TESS) have enabled astronomers to greatly improve their understanding of the bizarre environment of KELT-9 b, one of the hottest planets...

In this video, two days prior to the GOES-O launch, NASA Goddard Producer Silvia Stoyanova visits Cape Canaveral's Air Force Station, launch pad 37, to talk to NASA GOES N-P Deputy Project Manager Andre' Dress, about the factors that...

That's the promise of robotic refueling on orbit: aging satellites can get a new lease on life from a robotic machine making a service call. Or, at least, the dream of such a system got dramatically closer after...

NASA scientists don't often learn that their spacecraft is at risk of crashing into another satellite. But when Julie McEnery, the project scientist for NASA's Fermi Gamma-ray Space Telescope, checked her email on March 29,...

NASA's highly anticipated Robotic Refueling Mission (RRM) began operations on the International Space Station with the Canadian Dextre robot and RRM tools March 7-9, 2012, marking important milestones in satellite-servicing technology...

After a four and a half day journey from the Earth, the Lunar Reconnaissance Orbiter, or LRO, has successfully entered orbit around the moon. Engineers at NASA's Goddard Space Flight Center in Greenbelt, Md., confirmed the spacecraft's...

The main science goal of NASA's OSIRIS-REx mission is to briefly touch down on near-Earth asteroid Bennu and collect a sample of fine-grained material, but the asteroid’s unexpected roughness could pose a hazard to...
