A Winter’s View Of A Gullied Crater
April 19, 2017 – This image from NASA’s Mars Reconnaissance Orbiter (MRO) shows the location with the most impressive known gully activity in Mars’ northern hemisphere. Gullies are active in the winter due to carbon dioxide frost, but northern winters are shorter and warmer than southern winters, so there is less frost and less gully activity. Read More
The Arrhythmic Beating Of A Black Hole Heart
April 19, 2017 – At the center of the Centaurus galaxy cluster, there is a large elliptical galaxy called NGC 4696. Deeper still, there is a supermassive black hole buried within the core of this galaxy. Read More
Tiny Probes Hold Big Promise For Future NASA Missions
April 19, 2017 – A team of NASA engineers has been working on a new type of Thermal Protection System (TPS) for spacecraft that would improve upon the status quo. Read More

An Air Force Academy graduate will travel to the International Space Station April 20 to conduct research NASA hopes will eventually lead to a mission to Mars. Astronaut Col. Jack Fischer will take the six-hour flight to the station, more than 200 miles above the Earth, with cosmonaut Fyodor Yurchikhin of Roscosmos, Russia’s State Corporation for Space Activities, aboard the Russian-made Soyuz MS-04 spacecraft.
Radar images of asteroid 2014 JO25 were obtained in the early morning hours on Tuesday, with NASA’s 70-meter (230-foot) antenna at the Goldstone Deep Space Communications Complex in California. The images reveal a peanut-shaped asteroid that rotates about once every five hours. The images have resolutions as fine as 25 feet (7.5 meters) per pixel.
Spacecraft rely on liquids for everything from fuel to life support systems for astronauts. Storing these liquids at the correct temperature and pressure is essential to prevent loss of fluids or failure of a storage tank. Human life in space is a balancing act of reliable systems and meticulous planning.
New Study Ranks Hazardous Asteroid Effects From Least To Most Destructive

If an asteroid struck Earth, which of its effects—scorching heat, flying debris, towering tsunamis—would claim the most lives? A new study has the answer: violent winds and shock waves are the most dangerous effects produced by Earth-impacting asteroids.
NASA scientists from across the agency will present their latest findings and perspectives on topics ranging from the origins and evolution of life on Earth to the search for habitable environments and life in our solar system and beyond during the 2017 Astrobiology Science Conference, April 24-28 in Mesa, Arizona.
