NASA will send crew underseas to prep for deep space missions

In preparation for future deep space missions, NASA is planning to send an international crew into the watery depths of the Atlantic Ocean. This will be done as part of the space agency’s two week NASA Extreme Environment Mission Operations 20 expedition, more commonly referred to as “NEEMO”. The expedition is currently scheduled to start on July 20, and will be tasked with testing techniques and tools that may be used for spacewalks in the future in places with differing surfaces and levels of gravity.

NASA tests new avoidance systems for UAVs

NASA tests new avoidance systems for UAVs

NASA is has developed a new sense-and-avoid system that will let unmanned aerial vehicles (UAV) fly routine operations. The technology is currently undergoing its third round of testing. The researchers will use live data to validate the aircraft's trajectory, sensor, and other simulation models. The real-time data collection is designed to help the UAV move out of the path of incoming hazards like other aircraft.

NASA’s Cassini captures rare, triple crescent moon on Saturn

NASA’s Cassini captures rare, triple crescent moon on Saturn

NASA's Cassini spacecraft, launched in 1997, is on a mission to study Saturn and its mesmerizing rings and moons. Saturn has nine named moons and a total of fifty-three natural satellites in its orbit. As the multiple moons wax and wane in light, they create an image that looks like it belongs in a science fiction movie instead of our own solar system. This triple crescent moon sighting was captured by Cassini in March, but has just now been released by NASA.

Icefin robot could be how NASA explores Europa’s icy oceans

Icefin robot could be how NASA explores Europa’s icy oceans

Georgia Tech has a new robotic vehicle called Icefin, and it is designed to explore the depths of the ocean in icy regions. Previously Icefin was used to explore beneath the Ross Ice Shelf in Antarctica, and in the future it could have a mission that extends beyond Earth. The technology could be key to getting a look at the ocean that (likely) lies beneath the icy shell of Europa, one of Jupiter's moons. NASA has been working on plans to explore the frozen moon.

Visualizing where NASA’s Pluto and Ceres craft are right now in space

Visualizing where NASA’s Pluto and Ceres craft are right now in space

Today we watch NASA approach Pluto and Ceres, unfurling space mysteries aplenty. New images are appearing today of both the largest object in the asteroid belt and our furthest sun-circling cousin Pluto appear - but what we want to do is show you where the craft are. What you're about to see is where NASA is as far as space cruisers, first with the NASA Dawn spacecraft, then with the Pluto mission craft New Horizons. They're very, very far away from one another, but they're both just a stone's throw away from their respective goals.

NASA theorizes how lake depressions on Titan were formed

NASA theorizes how lake depressions on Titan were formed

Titan is one of Saturn's moons and one of the most interesting things about the moon is that it has lots of seas and lakes that are filled with liquid hydrocarbons. One thing that puzzles NASA scientists about the lakes of hydrocarbons on the surface of the moon is what process exactly creates the depression that the hydrocarbon lakes fill. Some of the depressions aren't filled with liquids.

NASA collects all of its space photos into single image gallery

NASA collects all of its space photos into single image gallery

If your hobbies include browsing various space photos, NASA has just made your day. The agency has unveiled a huge photo library that features every photo from past to present, totaling up to over 138,000 images. Sources include photos taken by the Hubble, JPL (Jet Propulsion Lab), and missions including Apollo. Called the NASA Images collection, the gallery was built by Luna Imaging, and combines over 70 previous galleries into a single, searchable database.

NASA’s Cassini spacecraft returns incredible pics of Dione

NASA’s Cassini spacecraft returns incredible pics of Dione

NASA's spacecraft Cassini has returned high-resolution and quite impressive images of Dione, Saturn's moon. The spacecraft took the images during its most recent flyby of the moon (earlier this week), and NASA has made them available as unprocessed RAW images, a more particular selection of which can be found at the CICLOPS website. This isn't the last we'll be getting images of Dione, though, as another flyby will be happening in a couple months with more imaging being planned.

How Silver Ants use hair like NASA’s new heat shield tech

How Silver Ants use hair like NASA’s new heat shield tech

The Saharan Silver Ant is discovered to dissipate heat using shiny silver hairs covering its entire body. Norman Nan Shi, assistant professor of applied physics at Columbia Engineering, has shown that the hairs of the Saharan Silver Ant act like heat shields, not entirely unlike NASA's space suit materials being developed for use by firefighters here on Earth. These ants live in an environment which can get extremely hot, up to 70°C (158°F). To make due when they need to forage for food, they've developed a rather intense bit of natural resistance, making them as shiny as they are cool.

NASA’s Europa mission passes first major review

NASA’s Europa mission passes first major review

NASA is hot to explore Europa, which is one of the moons orbiting Jupiter. The reason that Europa is such an interesting place to NASA is because it is believed to be one of the most likely places to find life outside of Earth. NASA has a mission concept for investigating Europa and that plan has successfully passed its first major review by the space agency.

NASA high-temp materials for spacecraft may help save firefighters

NASA high-temp materials for spacecraft may help save firefighters

NASA research and technology often spills over into the civilian world as time goes by. Over the years, we have seen a number of products become very popular in the civilian world that originated with NASA such as hook and loop closure material and other stuff. NASA is working on new technology to protect spacecraft during the fiery reentry to Earth by layering different heat resistant materials.

NASA spacecraft spots dust cloud around the moon

NASA spacecraft spots dust cloud around the moon

The moon — meaning our moon — has a cloud of dust around it described as lopsided, and it is confounding researchers. Apollo 15 and 17 crews had observed a glow around the moon that was thought to be due to dust, but this latest dust observation — which is thanks to NASA’s LADEE — is said to be different. The Lunar Atmosphere and Dust Environment Explorer (LADEE) is a spacecraft with a dedicated “dust instrument”, and it made its observations while on a low-altitude orbit mission.
