NASA Space Laser Completes 2,000-mile Road Trip

ICESat-2's laser instrument has shipped from NASA Goddard, where it was built and tested, to Arizona, where it will be assembled with its spacecraft.

New Study Finds Sea Level Rise Accelerating

Global sea level rise has accelerated in recent decades, rather than increase at a steady rate, according to a new study based on 25 years of NASA and European satellite data.

Celebrating 60 Years of Groundbreaking U.S. Space Science

Sixty years ago, the U.S. launched Explorer 1, rocketing into the Space Age.

Explorer 1: The Beginning of American Space Science

Sixty years ago, the hopes of Cold War America soared into the night sky as a rocket lofted skyward above Cape Canaveral, a soon-to-be-famous barrier island off the Florida coast.

NASA Team Studies Middle-aged Sun by Tracking Motion of Mercury

As the Sun ages and loses mass, the orbits of the planets are expanding. NASA and MIT scientists indirectly measured this mass loss and other solar parameters by looking at changes in Mercury’s orbit.

NASA Goddard Year in Review - 2017

A look back at 2017 at NASA Goddard.

Prolific Earth Gravity Satellites End Science Mission

After more than 15 productive years in orbit, the U.S./German GRACE (Gravity Recovery and Climate Experiment) satellite mission has ended science operations.

New Gravity Map Suggests Mars Has a Porous Crust

NASA scientists have found evidence that Mars’ crust is not as dense as previously thought, a clue that could help researchers better understand the Red Planet’s interior structure and evolution.

NASA Flights Map Summer Melt of Greenland Land Ice

Operation IceBridge is flying in Greenland to measure how much ice has melted over the course of the summer from the ice sheet. The flights, which began on Aug. 25 and will go on until Sept. 21, repeat paths flown this spring and aim to monitor seasonal changes in the elevation of the ice sheet.

NASA's IceBridge Surveys Glaciers in Northeast Greenland

NASA's Operation IceBridge is flying its summer Arctic land ice campaign in Greenland, continuing its measurements of the Greenland Ice Sheet and its outlet glaciers.

NASA's ICESat-2 Preps for Laser Tests

Lasers that will fly on NASA’s Ice, Cloud and land Elevation Satellite-2, or ICESat-2, are about to be put to the test at the agency’s Goddard Space Flight Center in Greenbelt, Maryland.

NASA, Norway to Develop Arctic Laser-Ranging Station

NASA and the Norwegian Mapping Authority are partnering to develop a state-of-the-art satellite laser ranging station 650 miles from the North Pole.

Goddard Hosts 8th Annual Science Jamboree for Employees

The Goddard Office of Communications and the Goddard Sciences and Exploration Directorate produced the eighth annual Science Jamboree on Wednesday, July 12, 2017.

Goddard Welcomes Nearly 450 Summer Interns

Almost 450 interns will complete their "10-week job interview" at NASA's Goddard Space Flight Center this summer.

Sweet 16: Goddard Teams Fly Extraordinary Number of Payloads in 2017

Sixteen different missions whose instruments and components were developed at least in part with funding from the center’s Internal Research and Development, or IRAD, program have either launched or are scheduled to launch this year aboard commercial launch vehicles, sounding rockets, balloons, and high-altitude research aircraft.

NASA's Fleet of Satellites Keep an Eye on Earth

No planet is better studied than the one we actually live on.

NASA Celebrates Earth Day with Public Events, Online Activities

This year, NASA will celebrate Earth Day, April 22, with a variety of live and online activities Thursday and Friday, April 20-21, to engage the public in the agency’s mission to better understand and

NASA Celebrates Earth Day by Letting Us All #AdoptThePlanet

NASA invites people around the world to help us celebrate Earth Day 2017 by "adopting" one of 64,000 individual pieces of Earth as seen from space.

NASA Awards Cooperative Agreement to the University of Maryland

NASA has awarded a cooperative agreement to the University of Maryland at College Park, Maryland, to continue collaborative research in the field of Earth systems science.

NASA Invites Media to 55th Annual Robert H. Goddard Memorial Symposium

Media are invited to meet science and engineering leaders at the 55th Robert H. Goddard Memorial Symposium in Greenbelt, Maryland, on March 8-9, 2017.

Earth’s Magnetic Fields Could Track Ocean Heat, NASA Study Proposes

As Earth warms, much of the extra heat is stored in the planet’s ocean. Monitoring the magnitude of that heat content is difficult, but a surprising feature of the tides could help.

Now 40, NASA's LAGEOS Set the Bar for Studies of Earth

Still going strong after 40 years, LAGEOS was NASA's first orbiter dedicated to satellite laser ranging. The satellite transformed studies of Earth’s shape, rotation and gravity field.

NASA Station Leads Way for Improved Measurements of Earth Orientation, Shape

NASA demonstrated advanced technology for making precise measurements of Earth's orientation and rotation - information needed for navigation of all space missions and geophysical studies of Earth.

NASA, Partner Space Agencies Measure Forests In Gabon

A contingent of NASA airborne instruments and scientists on the ground has joined colleagues from space agencies in Gabon and Europe this month to study the dense African tropical forests in Gabon.

NASA Contributes to Global Standard for Navigation, Studies of Earth
