NASA has had enough of astrology. Astronomers have spent years patiently trying to explain why zodiac signs are not science, and NASA finally seems fed up with the public’s obsession with them. NASA just dropped the ultimate astrology smackdown in a Tumblr post that’s since gone viral.
NASA Wants To Send A Submarine To Explore Seas Of Saturn's Moon Titan
Scientists are investigating the idea of sending a submarine to “explore the liquid methane seas of Saturn’s Moon Titan.” NASA is investigating the idea of sending a submarine to “explore the liquid methane seas of Saturn’s Moon Titan.” The vehicle, which is being developed under the agency’s Innovative Advanced Concepts Program, has been designed to “autonomously carry out detailed scientific investigations under the surface of Kraken Mare.” This body of water is Titan’s largest sea to the north with a span of about 621 miles and a depth of about 984 feet. In a diagram linked to Phase II of the project, the submarine includes features such as a hydrodynamic skin, meteorology sensor, and four thrusters. Meanwhile, a NASA Glenn Research Center video shows a simulation where the vehicle would be able to quickly analyze objects on the seafloor. According to Mental Floss, should the concept become real, the earliest launch would likely be in 2040.
The 16th century Portuguese navigator Ferdinand Magellan and his crew had plenty of time to study the southern sky during the first circumnavigation of planet Earth. As a result, two fuzzy cloud-like objects easily visible to southern hemisphere skygazers are known as the Clouds of Magellan, now understood to be satellite galaxies of our much larger, spiral Milky Way galaxy. About 160,000 light-years distant in the constellation Dorado, the Large Magellanic Cloud (LMC) is seen here in a remarkably deep, colorful, image. Spanning about 15,000 light-years or so, it is the most massive of the Milky Way's satellite galaxies and is the home of theclosest supernova in modern times, SN 1987A. The prominent patch below center is 30 Doradus, also known as the magnificentTarantula Nebula, is a giant star-forming region about 1,000 light-years across.
When she is not training astronauts, Mari
Forrestel works in Mission Control as an Environmental and Thermal Operating Systems Specialist.
Mari had an early interest in space ever since
she was a little girl and her father would tell stories about working in the
Arecibo Observatory in Puerto Rico during the time when SETI was being
conducted by Carl Sagan in the 70s. She is living out her childhood dreams
Today we had a ventilation and clean up lesson.
The cleanup part is tricky and happens with the fan similar to the mockup below
and a filter after having a combustion or fire event on board station.
Obviously, in a confined environment the contaminants from a fire would not be
healthy to breath. One of the first automatic software responses resulting
after a fire event, is to shut down ventilation systems, so that we do not
spread containments throughout the station. But we have to clean up the air
using a number of different resources.
On a more routine basis (every Saturday), we wipe
down surfaces and vacuum. In space, different from the ground, dust/lint
collects on all surfaces, including the walls and even the ceiling!

Ever thought about how much a pain it would be
to not have gravity keep things where you put them? One of the side benefits of
cleaning, is finding things you lost, or the crew before you lost, or the crew
before that. The air flow through the stations results in ventilation ducts
serving as the “lost and found” spots, where everything that is lost travels
