Hubble Telescope Enters 25th Year of Service

NASA May 12, 2014 On April 24, 1990, the space shuttle Discovery lifted off from Earth with the Hubble Space Telescope nestled securely in its bay. The following day, Hubble was released into space, ready to peer into the vast unknown of space. NASA’s Hubble Space Telescope recently marked its 24th year in space and to celebrate its 25th year, ... Read More »

Jupiter’s Moon Ganymede May Harbor Ice-Ocean Layers

NASA JPL May 01, 2014 The largest moon in our solar system, a companion to Jupiter named Ganymede, might have ice and oceans stacked up in several layers like a club sandwich, according to new NASA-funded research that models the moon’s makeup. Previously, the moon was thought to harbor a thick ocean sandwiched between just two layers of ice, one ... Read More »

Laser Communication Breakthrough – 80 Megabits/sec from Moon

ESA April 25, 2014 Just before NASA’s latest Moon mission ended last week, an ESA telescope received laser signals from the spacecraft, achieving data speeds like those used by many to watch movies at home via fibre-optic Internet. During an intense, three-day effort starting on 1 April, ESA’s Optical Ground Station in Spain received data signals via laser from the ... Read More »

Twenty-Six Asteroids Exploded Over Earth From 2000-2013

April 23, 2014 Between 2000 and 2013, a network of sensors that monitors Earth around the clock listening for the infrasound signature of nuclear detonations detected 26 explosions on Earth ranging in energy from 1-600 kilotons – all caused not by nuclear explosions, but rather by asteroid impacts. These findings were recently released from the Nuclear Test Ban Treaty Organization, which operates ... Read More »

Has a Second Earth Just Been Discovered?

NASA April 17, 2014 Using NASA’s Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting a star in the “habitable zone” — the range of distance from a star where liquid water might pool on the surface of an orbiting planet. The discovery of Kepler-186f confirms that planets the size of Earth exist in the habitable zone of ... Read More »

3-D Printing to Revolutionize Space Travel

ESA April 15, 2014 This close-up shows a titanium ball manufactured by 3D printing. ESA is investigating the potential of this promising new technology to transform the way space missions are put together. 1. Items impossible to make any other way “This design is a perfect example of additive manufacturing (AM),” explains ESA materials engineer Benoit Bonvoisin. “These balls are ... Read More »

Possible Moon Found Around Alien World

NASA JPL April 10, 2014 Titan, Europa, Io and Phobos are just a few members of our solar system’s pantheon of moons. Are there are other moons out there, orbiting planets beyond our sun? NASA-funded researchers have spotted the first signs of an “exomoon,” and though they say it’s impossible to confirm its presence, the finding is a tantalizing first ... Read More »

Ocean Detected on Saturn’s Moon Enceladus

NASA JPL April 03, 2014 NASA’s Cassini spacecraft and Deep Space Network have uncovered evidence Saturn’s moon Enceladus harbors a large underground ocean of liquid water, furthering scientific interest in the moon as a potential home to extraterrestrial microbes. Researchers theorized the presence of an interior reservoir of water in 2005 when Cassini discovered water vapor and ice spewing from ... Read More »

Rosetta Spacecraft Sees Its Destination Comet

ESA March 27, 2014 ESA’s Rosetta spacecraft has caught a first glimpse of its destination comet since waking up from deep-space hibernation on 20 January. These two ‘first light’ images were taken on 20 and 21 March by the OSIRIS wide-angle camera and narrow-angle camera, as part of six weeks of activities dedicated to preparing the spacecraft’s science instruments for ...

Curiosity Enters Region of Martian Sandstone

NASA JPL March 24, 2014 Variations in the stuff that cements grains together in sandstone have shaped the landscape surrounding NASA’s Curiosity Mars rover and could be a study topic at the mission’s next science waypoint. On a journey with many months yet to go toward prime destinations on the lower slope of Mount Sharp, Curiosity is approaching a site ... Read More »
