Washington, D.C. – On Thanksgiving Day, we thank God for the abundant blessings in our lives. As we gather with family and friends to celebrate this season of generosity, hope, and gratitude, we commemorate America’s founding traditions of faith, family, and friendship, and give thanks for the principles of freedom, liberty, and democracy that make our country exceptional in the history of the world.
This November marks 400 years since the Mayflower and its passengers faced the unknown and set sail across the Atlantic Ocean.
Pasadena, CA – NASA says that when an ice cube is exposed to a heat source, like warm water or air, it melts. So, it’s no surprise that a warming climate is causing our glaciers and ice sheets to melt. However, predicting just how much the glaciers and ice sheets will melt and how quickly – key components of sea level rise – is not nearly as straightforward.
Glaciers and ice sheets are far more complex structures than ice cubes. They form when snow accumulates and is compressed into ice by new snow over many years.
Washington, D.C. – While scientists around the world are confined to their homes during the COVID-19 Coronavirus pandemic, Earth observing satellites continue to orbit and send back images that reveal connections between the pandemic and the environment. “Satellites collect data all the time and don’t require us to go out anywhere,” Hannah Kerner, an assistant research professor at the University of Maryland in College Park, said.
Kerner is among eight researchers recently awarded a rapid-turnaround project grant, which supports investigators as they explore how COVID-19 Coronavirus lockdown measures are impacting the environment and how the environment can affect how the virus is spread.
Greenbelt, MD – NASA says a small but evolving dent in Earth’s magnetic field can cause big headaches for satellites.
Earth’s magnetic field acts like a protective shield around the planet, repelling and trapping charged particles from the Sun. But over South America and the southern Atlantic Ocean, an unusually weak spot in the field – called the South Atlantic Anomaly, or SAA – allows these particles to dip closer to the surface than normal.
Washington, D.C. – NASA passed a major milestone Friday in its goal to restore America’s human spaceflight capability when SpaceX’s Crew Dragon returned to Earth after a five-day mission docked to the International Space Station.
About 6 hours after departing the space station, Crew Dragon splashed down at 7:45am CT approximately 230 miles off the coast of Cape Canaveral, Florida. SpaceX retrieved the spacecraft from the Atlantic Ocean and is transporting it back to port on the company’s recovery ship.
Washington, D.C. – NASA astronauts Robert Behnken and Douglas Hurley arrived at the International Space Station on Sunday aboard the first commercially built and operated American spacecraft to carry humans to orbit, opening a new era in human spaceflight.
The pair of astronauts docked to the space station’s Harmony module at 90:16am CT Sunday as the microgravity laboratory flew 262 miles above the border northern China and Mongolia.
Pasadena, CA – A major ocean current in the Arctic is faster and more turbulent as a result of rapid sea ice melt, a new study from NASA shows. The current is part of a delicate Arctic environment that is now flooded with fresh water, an effect of human-caused climate change.
Using 12 years of satellite data, scientists have measured how this circular current, called the Beaufort Gyre, has precariously balanced an influx of unprecedented amounts of cold, fresh water – a change that could alter the currents in the Atlantic Ocean and cool the climate of Western Europe.
Washington, D.C. – On Sunday, January 19th, 2020 NASA and SpaceX completed a launch escape demonstration of the company’s Crew Dragon spacecraft and Falcon 9 rocket. This was the final major flight test of the spacecraft before it begins carrying astronauts to the International Space Station under NASA’s Commercial Crew Program.
The launch escape test began at 9:30am CT with liftoff from historic Launch Complex 39A at NASA’s Kennedy Space Center in Florida on a mission to show the spacecraft’s capability to safely separate from the rocket in the unlikely event of an inflight emergency.
SpaceX, NASA to launch final, major In-Flight Abort Demonstration before Astronauts board Crew Dragon Spacecraft
Washington, D.C. – NASA and SpaceX postponed the test until Sunday, January 19th, due to sustained winds and rough seas in the recovery area. Further updates will be available from NASA’s commercial crew blog.
NASA and SpaceX are preparing to launch the final, major test before astronauts fly aboard the Crew Dragon spacecraft and Falcon 9 rocket to the International Space Station as part of the agency’s Commercial Crew Program.
Pasadena, CA – NASA says the Antarctic Circumpolar Current flows in a loop around Antarctica, connecting the Atlantic Ocean, Pacific Ocean and Indian Ocean. It is one of the most significant ocean currents in our climate system because it facilitates the exchange of heat and other properties among the oceans it links.
But how the current transfers heat, particularly vertically from the top layer of the ocean to the bottom layers and vice versa, is still not fully understood. This current is very turbulent, producing eddies – swirling vortices of water similar to storms in the atmosphere – between 30 to 125 miles (50 to 200 kilometers) in diameter.
