We’re On A Mission To Study The Zone Where Earth Meets Space!

How NASA Earth Data Aids America

Today we roll out a new communications project that highlights some of the many ways that NASA's Earth observations help people strengthen communities across the United States.

Space for U.S. features stories on how Earth science data is used to make informed decisions about public health, disaster response and recovery and environmental protection. By highlighting advanced technology from a global perspective, our data helps provide people achieve groundbreaking insights.

For example, a family-owned coffee company in Maine used our sunlight, wind and temperature data to determine the placement of their power-generating solar wall.

Space for U.S. features 56 stories illustrating how our science has made an impact in every state in the nation as well as the District of Columbia, Puerto Rico and regions along the Atlantic, Pacific, Gulf of Mexico, and the Great Lakes.

For six decades, we've used the vantage point of space to better understand our home planet and improve lives. Using Space for U.S., you can browse through stories about how applied Earth science either by state or by topics such as animals, disasters, energy, health, land and water. Each click brings you a story about how people are putting NASA data to work.

Explore the true stories behind the innovative technology, groundbreaking insights, and extraordinary collaboration happening right here in the United States with Space for U.S.

Meet Megan McArthur, NASA Astronaut & Crew-2 Pilot

NASA astronaut Megan McArthur will launch on Friday, April 23 to the International Space Station as the pilot for NASA’s SpaceX Crew-2 mission! This is the second crew rotation flight with astronauts on the Crew Dragon spacecraft and the first launch with two international partners as part of the agency’s Commercial Crew Program. McArthur is responsible for spacecraft systems and performance and is assigned to be a long-duration space station crew member. While this is her first trip to the space station, McArthur’s career has prepared her well for this important role on the Crew-2 team!

McArthur was born in Honolulu, Hawaii and grew up in California. She is a former Girl Scout and has a Bachelor of Science in Aerospace Engineering from the University of California, Los Angeles and a Ph.D. in Oceanography from the University of California, San Diego where she performed research activities at the Scripps Institution of Oceanography.

While in graduate school, McArthur conducted research, served as Chief Scientist for at-sea data collection operations, and planned and led diving operations. She also volunteered at the Birch Aquarium at Scripps, conducting educational demonstrations for the public from inside a 70,000-gallon exhibit tank of the California Kelp Forest. Her experience conducting research in extreme conditions will certainly come in handy once she’s aboard the space station, as a big part of the astronauts’ job involves running research experiments in microgravity.

McArthur was selected as a NASA astronaut in 2000 and flew her first spaceflight aboard STS-125, the final space shuttle mission to service the Hubble Space Telescope. She worked as the flight engineer during launch and landing, and also served as the shuttle's robotic arm operator as she carefully retrieved the telescope and placed it in the shuttle’s cargo bay for servicing. The successful mission improved the telescope's capabilities and extended its life – and Hubble is still helping us make discoveries about our universe.

Global Temperature by the Numbers

The Year

4th Hottest

2018 was the fourth hottest year since modern recordkeeping began. NASA and the National Oceanic and Atmospheric Administration work together to track temperatures around the world and study how they change from year to year. For decades, the overall global temperature has been increasing.

Over the long term, world temperatures are warming, but each individual year is affected by things like El Niño ocean patterns and specific weather events.

1.5 degrees

Globally, Earth’s temperature was more than 1.5 degrees Fahrenheit warmer than the average from 1951 to 1980.

The Record

139 years

Since 1880, we can put together a consistent record of temperatures around the planet and see that it was much colder in the late-19th century. Before 1880, uncertainties in tracking global temperatures were too large. Temperatures have increased even faster since the 1970s, the result of increasing greenhouse gases in the atmosphere.

Five Hottest

The last five years have been the hottest in the modern record.

6,300 Individual Observations

Scientists from NASA use data from 6,300 weather stations and Antarctic research stations, together with ship- and buoy-based observations of sea surface temperatures to track global temperatures.

The Consequences

605,830 swimming pools

As the planet warms, polar ice is melting at an accelerated rate. The Greenland and Antarctic ice sheets lost about 605,830 Olympic swimming pools (400 billion gallons) of water between 1993 and 2016.

8 inches

Melting ice raises sea levels around the world. While ice melts into the ocean, heat also causes the water to expand. Since 1880, sea levels around the world have risen approximately 8 inches.

71,189 acres burned

One symptom of the warmer climate is that fire seasons burn hotter and longer. In 2018, wildfires burned more than 71,189 acres in the U.S. alone.

46% increase in CO2 levels

CO2 levels have increased 46 percent since the late 19th Century, which is a dominant factor causing global warming.

4. Gale Crater on Mars

This look from our Curiosity Mars rover includes several geological layers in Gale crater to be examined by the mission, as well as the higher reaches of Mount Sharp beyond. The redder rocks of the foreground are part of the Murray formation. Pale gray rocks in the middle distance of the right half of the image are in the Clay Unit. A band between those terrains is "Vera Rubin Ridge," where the rover is working currently. The view combines six images taken with the rover's Mast Camera (Mastcam) on Jan. 24, 2017.
