At the foundation of virtually all airborne, space-based and ground-based Earth observations is the TRF, or Terrestrial Reference Frame. The TRF relies on an accurate calculation of the geocenter of the Earth (the center...

OSIRIS-REx launched Thursday, September 8 at 7:05PM on an Atlas V rocket on a journey to study asteroid Bennu and return a sample to Earth. Thousands of visitors watched the launch, some of whom were part of a NASA...

The urgency of Earth science and climate studies took the spotlight Friday, Nov. 5, 2021, as U.S. Vice President Kamala Harris visited NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Alongside NASA...

On schedule to launch in the mid-2020s, NASA’s Wide Field Infrared Survey Telescope (WFIRST) mission will help uncover some of the biggest mysteries in the cosmos. The state-of-the-art telescope on the...

NASA’s Near Space Network fulfills the essential needs of user missions, empowering them with mission-critical communications and navigation services and enabling the transmission of science and exploration data to and from...

The James Webb Space Telescope is one the most ambitious, and technically complex missions NASA has ever set its focus on. Building an infrared observatory of this magnitude, power and complexity has never been attempted...

Humans have always looked up at the sky. They used astronomy to track time, orient their cities, decide when to plant their crops, and even based their religious practices on their celestial world. But there was much more to learn.<br/>

Using measurements from NASA's Aura satellite, scientists studied chlorine within the Antarctic ozone hole over the last several years, watching as the amount slowly decreased. This is the first definitive evidence of the success of the...

The Global Fire WEather Database (GFWED) integrates different weather factors influencing the likelihood of a vegetation fire starting and spreading. It is based on the Fire Weather Index (FWI) System, which tracks the...

Like to catch snowflakes? Try using a card instead of your tongue! Join the Global Snowflake Network for the International Polar Year. NASA Goddard Space Flight Center invites you to be a part of this special data collection effort....

NASA's Fermi Gamma-ray Space Telescope has detected beams of antimatter launched by thunderstorms. Acting like enormous particle accelerators, the storms can emit gamma-ray flashes, called TGFs, and high-energy electrons and...

When she was a little girl, Carrie Anderson dreamed of becoming an astronomer. Now, as a space scientist at NASA Goddard Space Flight Center, Carrie studies the atmosphere on Titan, one of Saturn's moons and the second largest moon...

NASA's MODIS satellite instrument reveals how air pollution may alter clouds, affecting global temperatures. This narrated visualization illustrates the effect by showing how ship exhaust leaves brights cloud trails in clean ocean air....

On March 17, 2014 the Global Precipitation Measurement (GPM) mission's Core Observatory flew over the East coast's last snow storm of the 2013-2014 winter season. This was also one of the first major snow storms observed by GPM...

In part 3, Dr. Garvin talks about the recent science and exploration breakthroughs at Earth's moon and explains why there's so much interest these days in near-Earth objects.

Black widow spiders and their Australian cousins, known as redbacks, are notorious for an unsettling tendency to kill and devour their male partners. Astronomers have noted similar behavior among two rare breeds of binary...

During the June 2011 lunar eclipse, scientists will be able to get a unique view of the moon. While the sun is blocked by the Earth, LRO's Diviner instrument will take the temperature on the lunar surface. Since different rock sizes...

Merging data on high-energy bursts seen on Earth by NASA's Fermi Gamma-ray Space Telescope with data from ground-based radar and lightning detectors, scientists have completed the most detailed analysis to date of the types of...

NASA satellites use very sensitive devices called magnetometers to measure the magnetic fields of planets. Like very sensitive compasses, these devices can measure both direction and strength of planetary magnetic fields. <b<b<br/>r/>r/>

Rising carbon dioxide levels in the atmosphere are driving changes in Earth’s climate. But scientists are still trying to answer important questions about how carbon dioxide emissions get absorbed by the land and the ocean — and how...

Join NASA's Goddard Space Flight Center in Greenbelt, Md., in celebrating Black History Month. Each week in February, a different African-American employee from GSFC will be featured. In the opening week, two will be featured. The...

Will climate change drastically reduce our food production, or will it change what we produce?<b<b<br/>r/>r/>

Understanding the Sun’s behavior is an important part of life in our solar system. The Sun’s powerful outbursts can disturb the satellites and communications signals traveling around Earth, or one day, Artemis...

On February 27, 2019, we celebrate five years in orbit for the NASA/JAXA Global Precipitation Measurement mission, or GPM. Launched from Japan on February 27, 2014, GPM has changed the way we see precipitation. It has provided...
