Greenbelt, MD – By studying the chemical elements on Mars today, including carbon and oxygen, NASA scientists can work backwards to piece together the history of a planet that once had the conditions necessary to support life.
Weaving this story, element by element, from roughly 140 million miles (225 million kilometers) away is a painstaking process. But scientists aren’t the type to be easily deterred. Orbiters and rovers at Mars have confirmed that the planet once had liquid water, thanks to clues that include dry riverbeds, ancient shorelines, and salty surface chemistry.
Austin Peay State University School of Nursing graduate Hunter Burkhart describes life as an intensive care nurse during Coronavirus
Clarksville, TN – As the coronavirus pandemic rages across the world, thousands of Austin Peay State University School of Nursing graduates are in the trenches helping patients battle the disease.
One recent graduate, Hunter Burkhart, is a registered nurse at Vanderbilt University Medical Center’s medical intensive care unit.
Washington, D.C. – When NASA sends astronauts to the surface of the Moon in 2024, it will be the first time outside of watching historical footage most people witness humans walking on another planetary body. Building on these footsteps, future robotic and human explorers will put in place infrastructure for a long-term sustainable presence on the Moon.
NASA recently proposed a plan to go from limited, short-term Apollo-era exploration of the 1960s, to a 21st Century plan in a report to the National Space Council. With the Artemis program, we will explore more of the Moon than ever before to make the next giant leap – sending astronauts to Mars.
Nashville, TN – In order to stop the spread of the Coronavirus (COVID-19) pandemic, Tennesseans are now required by Tennessee Governor Bill Lee to stay home unless carrying out essential activities.
While Tennesseans are staying at home during this period, the Tennessee State Fire Marshal’s Office (SFMO) is urging Volunteer State residents to renew their commitment to practicing good fire safety habits in order to reduce the risk of starting a home fire that could result in an injury or, worse, a fatality.
Pasadena, CA – NASA’s Juno mission has provided its first science results on the amount of water in Jupiter’s atmosphere. Published recently in the journal Nature Astronomy, the Juno results estimate that at the equator, water makes up about 0.25% of the molecules in Jupiter’s atmosphere – almost three times that of the Sun.
These are also the first findings on the gas giant’s abundance of water since the agency’s 1995 Galileo mission suggested Jupiter might be extremely dry compared to the Sun (the comparison is based not on liquid water but on the presence of its components, oxygen and hydrogen, present in the Sun).
Mountain View, CA – Science fiction often imagines our future on Mars and other planets as run by machines, with metallic cities and flying cars rising above dunes of red sand. But the reality may be even stranger – and “greener.”
Instead of habitats made of metal and glass, NASA is exploring technologies that could grow structures out of fungi to become our future homes in the stars, and perhaps lead to more sustainable ways of living on Earth as well.
Washington, D.C. – In 2019, NASA celebrated the 50th anniversary of the agency’s Apollo 11 Moon landing, the most historic moment in space exploration, while also making significant progress toward putting the first woman and next man on the Moon by 2024 under the Artemis program.
Through America’s Moon to Mars exploration approach, Artemis gained bipartisan support this year among members of Congress, the U.S aerospace industry, as well as with international partners, including Canada, Australia, and Japan, and member states of the European Space Agency.
Greenbelt, MD – For the first time in the history of space exploration, NASA scientists have measured the seasonal changes in the gases that fill the air directly above the surface of Gale Crater on Mars.
As a result, they noticed something baffling: oxygen, the gas many Earth creatures use to breathe, behaves in a way that so far scientists cannot explain through any known chemical processes.
Over the course of three Mars years (or nearly six Earth years) an instrument in the Sample Analysis at Mars (SAM) portable chemistry lab inside the belly of NASA’s Curiosity rover inhaled the air of Gale Crater and analyzed its composition.
Washington, D.C. – NASA scientists opened an untouched rock and soil sample from the Moon returned to Earth on Apollo 17, marking the first time in more than 40 years a pristine sample of rock and regolith from the Apollo era has been opened. It sets the stage for scientists to practice techniques to study future samples collected on Artemis missions.
The sample, opened November 5th, in the Lunar Curation Laboratory at the agency’s Johnson Space Center in Houston, was collected on the Moon by Apollo 17 astronauts Gene Cernan and Jack Schmitt, who drove a 4-centimeter-wide tube into the surface of the Moon to collect it and another sample scheduled to be opened in January.
Pasadena, CA – A carved-out cloud of gas and dust looks like a celestial jack-o’-lantern in this image from NASA’s Spitzer Space Telescope.
A massive star – known as an O-type star and about 15 to 20 times heavier than the Sun – is likely responsible for sculpting this cosmic pumpkin. A recent study of the region suggests that the powerful outflow of radiation and particles from the star likely swept the surrounding dust and gas outward, creating deep gouges in this cloud, which is known as a nebula.
