Majority of Americans believe it is essential that the US remain...

WASHINGTON, D.C. (June 6, 2018) - Sixty years after the founding of NASA, most Americans say the U.S. should be at the forefront of global leadership in space exploration and believe that - even as private space companies emerge as increasingly important players - NASA's role is still vital for U.S. space exploration. In a national survey of 2,541 U.S. adults conducted March 27-April 9,…

Study explores options that optimize profit in broadband satellite constellations

Although broadband for everyone sounds like a great idea, it also carries great financial risk, resulting in bankruptcy…

Data discrepancies may affect understanding of the universe

One of the unsolved mysteries in modern science is why the expansion of the universe appears to be accelerating. Some scientists argue it is due to a theoretical dark energy that counteracts the pull of gravity, while others think Albert Einstein's long-accepted theory of gravity itself may need to be modified. As astrophysicists look for answers in the mountains of data gathered from astronomical observations,…

NASA analyzes Northern Indian Ocean rainfall of soaking separate cyclones

NASA analyzed rainfall in two tropical cyclones that developed in the Northern Indian Ocean, each bringing heavy rainfall. Within a week, separate cyclones, Tropical Storm Sagar and Cyclone Mekunu, hit Somalia and nearby Oman, respectively, and both dropped heavy rainfall in a region that is not accustomed to it. The first cyclone to strike the area, Sagar, formed from an area of thunderstorm activity located…

Study suggests Earth could have supported continental crust, life earlier than...

The early Earth might have been habitable much earlier than thought, according to new research from a group led by University of Chicago scientists. Counting strontium atoms in rocks from northern Canada, they found evidence that the Earth's continental crust could have formed hundreds of millions of years earlier than previously thought. Continental crust is richer in essential minerals than younger volcanic rock, which would…

Astronauts Safely in Orbit Following Launch to International Space Station

Three crew members are on their way to the International Space Station after launching from the Baikonur Cosmodrome in Kazakhstan at 7:12 a.m. EDT Wednesday (5:12 p.m. Baikonur time).

Russian and Georgian universities unite to study properties of solitons

Vasily Belashov (Kazan Federal University), Elena Belashova (Kazan National Research Technical University), and Oleg Kharshiladze (Tbilisi State University) used Mr. Belashov's recently proposed theory of dynamics of solitons to inquire into conditions under which solitons appear in the solar corona and the Earth's magnetosphere and ionosphere. Solitons behave more like particles. For instance, they don't create an observable interference pattern but rather "push off" each…

NASA finds some fragmented strength in Tropical Depression 05W

IMAGE: NASA's Aqua satellite revealed some cloud top temperatures in fragmented thunderstorms as cold or colder than minus 70 degrees (red) Fahrenheit (minus 56.6 degrees Celsius) on Tropical Depression 05W on... view more  Credit: Credits: NASA/NRL NASA obtained an infrared look at Tropical Depression 05W as it continued moving through the South China Sea. NASA's Aqua satellite found very cold cloud top temperatures and strong storms…

Engineers solve excessive heat removal from NASA’s Webb Telescope

How will NASA's James Webb Space Telescope shed the heat generated by its science instruments and their supporting electronics? To anyone who is not an engineer or scientist, the answer might be complex and "baffling," and it turns out the process is exactly that. Webb's four science instruments are held within a support structure called the integrated science instrument module (ISIM), located behind the telescope's…

NASA funds Rutgers scientists’ pursuit of the origins of life

IMAGE: Iron- and sulfur-containing minerals found on the early Earth (greigite, left, is one example) share a remarkably similar molecular structure with metals found in modern proteins (ferredoxin, right, is one... view more  Credit: Professor Vikas Nanda/Center for Advanced Biotechnology and Medicine at Rutgers What are the origins of life on Earth and possibly elsewhere? Did "protein nanomachines" evolve here before life began to catalyze and…
