NASA is developing a laser-based instrument for deployment on the International Space Station that will probe the depths of Earth's forests from space in a bid to reveal more about their role in the planet's carbon cycle. After its completion in 2018, this Global Ecosystem Dynamics Investigation (GEDI) lidar will join the likes of the Soil Moisture Active Passive satellite in studying Earth's vegetation on a global scale.  Read More

Curiosity's old and new paths (Image: NASA/JPL-Caltech/Univ. of Arizona)

After over two years on Mars, NASA’s Curiosity rover has reached its primary objective, Mount Sharp. Located in the center of Gale Crater, where the unmanned explorer has been studying geology of the Red Planet, Mount Sharp will be the centerpiece of a new program of study to locate areas where could or once could have supported microbial life.  Read More

As the European Space Agency's (ESA) Rosetta spacecraft continues its mission by accompanying comet 67P/Churyumov-Gerasimenko (67P, for short) on its journey into the inner solar system, sensing instruments have been studying it prior to an attempted a landing by Rosetta's Philae probe. As a result, the spacecraft has collected enough information to render a map of the various areas on the surface of the comet showing that it is composed of several different regions created by a range of forces acting upon the object.  Read More

NASA’s return to manned spaceflight took a couple of major steps forward this week with the completion of the Orion crew capsule and the attachment of it and the previously-completed service module to the adapter that will connect Orion to its rocket. This marks the completion of all major components of the spacecraft, which is due to make its first test flight in December.  Read More

Comets are often described as "dirty snowballs" of ice and dust, which suggests something that looks like what kids throw at each other in winter. But NASA’s Alice instrument package installed aboard the ESA Rosetta probe currently orbiting comet 67P/Churyumov-Gerasimenko has sent back its first science data, which shows that the comet is about as white and fluffy as a lump of coal.  Read More

A star accompanying a rare type of supernova in close orbit has been discovered by astronomers using NASA's Hubble Space Telescope. Confirming a long-held theory that the explosion originated in a binary star arrangement, observations verify that the companion star precipitated the destruction of the aging primary star by drawing off mass until its core collapsed and triggered a supernova event.  Read More

NASA’s Space Launch System (SLS) program has received the green light to progress after the completion of a critical design review. The next generation heavy launch system, which is designed to lift the Orion spacecraft for manned missions into deep space, is NASA’s most ambitious project since the 1960s and the most powerful rocket ever built, with 12 percent more thrust than the Saturn V booster used to send the Apollo missions to the Moon.  Read More

NASA’s Hubble and Spitzer telescopes have been used to examine a distant elliptical galaxy known as Sparky. The observations represent the first glimpse at the earliest stages of massive galaxy construction, shedding light on an area of frenzied star production in the early universe.  Read More

A collection of autonomous robots designed to scuttle around on distant planets looking for resources and material in much the same way that members of insect colonies do on Earth are currently being tested by NASA engineers. The robots, dubbed ‘swarmies’, are designed to individually survey an area, signal the others when they have found something of value, and then divide up the task of collecting the material and returning it to their base.  Read More

Artist's impression of New Horizons passing Pluto (Image: NASA)

Like a traveler on a very long road trip, a deep space probe has passed the last sign post before its destination. NASA has announced that its New Horizons probe has passed the orbit of Neptune – its last milestone before it flies by Pluto on July 14 next year. Launched in 2006, the piano-sized unmanned spacecraft is almost 2.75 billion mi (4.42 billion km) from Earth and is the fastest man-made object ever sent into space.  Read More
