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 aft...

LDCM is the Landsat Data Continuity Mission, continuing the Landsat program's 40-year data record of monitoring Earth's landscapes from space. LDCM will expand and improve on that record with observations that advance a w...

Near-Earth Objects, or NEO's, cross our planet's orbit on a regular basis, but only a handful are large enough to pose a threat. One of these objects is asteroid 1999 RQ36, a "leftover" from the formation of our solar syst...

The Chesapeake Bay receives water from the 64,000 square miles of land surrounding the bay and Landsat satellites are a critical and invaluable tool for characterizing the landscape and mapping it over time. Landsat data p...

An Earth-directed coronal mass ejection (CME) on Jan. 31, 2013 was accompanied by a large prominence eruption best visible in light with a wavelength of 304 angstroms. NASA's Solar Dynamics Observatory captured this footag...

Can you stuff all the sights and science of a 12-hour mission into just three minutes? Maybe not, but here's our first try, chronicling NASA's recent flight to Antarctica's remote Getz Ice Shelf, where Operation IceBridge ...

On July 18, 2012, a fairly small explosion of light burst off the lower right limb of the sun. Such flares often come with an associated eruption of solar material, known as a coronal mass ejection or CME -- but this one d...

The Landsat Data Continuity Mission (LDCM) is a collaboration between NASA and the U.S. Geological Survey that will continue the Landsat Program's 40-year data record of monitoring Earth's landscapes from space. LDCM will ...

NASA is preparing to launch the first in a series of three third generation advanced Tracking and Data Relay Satellites, known as TDRS-K. This latest addition to the fleet of seven will augment a space communications netwo...

When the next-generation space telescope was being designed, engineers had to ensure there was a place large enough to test it, considering it's as big as a tennis court. That honor fell upon the famous "Chamber A" in the ...

In orbit at 18,000 miles an hour, day and night change places every 90 minutes. Darkness and light, sleep and wake: it's tough to focus on precise tasks floating outside the International Space Station. But not if you're a...

As part of the first demonstration of laser communication with a satellite at the moon, scientists with NASA's Lunar Reconnaissance Orbiter (LRO) beamed an image of the Mona Lisa to the spacecraft from Earth.

The iconic i...

People who live north of the equator are experiencing both higher summer temperatures and a greater frequency of extreme bouts of heat, according to a NASA statistical analysis of decades of Northern Hemisphere temperature...

NASA's analysis of Earth's surface temperature found that 2012 ranked as the ninth warmest year since 1880. NASA scientists at the Goddard Institute for Space Studies (GISS) compare the average global temperature each year...

Day One of NASA's Robotic Refueling Mission (RRM) wraps, and mission planners are giving it high marks. Designed to push the boundaries of what robots can do in space, the five-day RRM effort has ambitious goals. Operation...

This is a sequence of Landsat-based data in the Pacific Northwest. There is one data set for each year representing an aggregate of the approximate peak of the growing season (around August). The data was created using a s...

In an important demonstration of new technical methodologies, from January 14-24, 2013, NASA engineers will try to simulate the transfer of fuel from one vehicle to another, in space, with nothing but robots doing the phys...

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 ...

Operación IceBridge: Explorando la Antártida

On Tuesday Nov. 13, 2012, the GPM core observatory was moved

from the clean room to the thermal vacuum chamber. The spacecraft, wrapped in

protective blankets, made the short trip by crane across the testing facility

Lightning in the clouds is directly linked to events that produce some of the highest-energy light naturally made on Earth: terrestrial gamma-ray flashes (TGFs). An instrument aboard NASA's Fermi Gamma-ray Space Telescope ...

Before 1979, there were less than a dozen known sungrazing comets. As of December 2012, we know of 2,500. Why did this number increase? With solar observatories like SOHO, STEREO, and SDO, we have not only better means of ...

In daylight our big blue marble is all land, oceans and clouds. But the night - is electric.

This view of Earth at night is a cloud-free view from space as acquired by the Suomi National Polar-orbiting Partnership Satelli...

The Evaporative Stress Index (ESI) provides objective, high-resolution information about the evaporation of water from land surface. The ESI model combines satellite data with other meteorological factors to determine how ...

To observe how winds move high in Earth's atmosphere, scientists sometimes release clouds of barium as tracers to track how the material corkscrews and sweeps around � but scientists have no similar technique to study the ...

The U.S. fire season in 2012 was by some measures a record-breaking season. NASA scientist Doug Morton discusses the links between climate and wildfires and the likelihood of seeing more extreme fire events in the future....
