Historic pics show worlds beyond our solar system
Image Gallery (6 images)
In two separate scientific show-stoppers, unprecedented direct images of planets outside of our own solar system have been captured by NASA's Hubble space telescope and terrestrial observatories in Hawaii. Over the past two decades astronomers have detected around 300 exoplanets and are rapidly finding more, but these have mostly been observed by methods such as monitoring the gravitational effects of a planet on its parent star rather than seen as a direct optical image. We now have the first visible-light snapshot of a planet circling another star from the Hubble, and the first-ever direct images of an exoplanetary system from the massive 8-meter Gemini North telescope on Mauna Kea.

Last call: Mars Phoenix lander mission winds down
Image Gallery (3 images)
The approaching Martian winter has spelled an end to the pioneering Phoenix Mars Lander mission. More than five months after reaching the red planet, the lander sent what is expected to be its final transmission back to Earth on November 2, exceeding its planned operational life-span by two months. Increased cloud, dust and the onset of colder temperatures mean that the robot is no longer receiving enough sunlight to charge its batteries and although engineers will keep the airwaves open, further communication with the lander is not expected.

Mining the moon: the Scarab lunar prospecting robot
Image Gallery (5 images)
Plans are afoot to have humans back on the moon by 2020, but if we want to make it more than just a brief visit and truly begin to colonize the solar system, the challenge will be to find ways to extract and exploit local resources that can help sustain a lunar outpost. That's where the Scarab comes in. The four-wheel, 880-pound lunar prospecting robot designed by Carnegie Mellon University's Robotics Institute, and soon to be field tested by NASA on the slopes of a dormant volcano in Hawaii, is equipped to drill and collect three-foot samples of soil and rock while operating in one of the harshest environments imaginable - the moon's southern pole. The rover will act as a terrestrial testbed for the development of technologies that it's hoped can be used to find hydrogen, oxygen and possibly even water, that could be mined from beneath the moon's surface.

Create the Future Design Contest: re-thinking the wheel
Image Gallery (6 images)
The NASA Tech Briefs Create the Future Design Contest began in 2002 as a platform for encouraging innovation in product design among engineers, entrepreneurs, and students around the globe. The 2008 competition is open until October 17, but already this year's entries have produced some very thought provoking product ideas and we'll be exploring some of the standouts in detail over coming weeks. The first cab off the rank is an attempt, in fact two attempts, to do what else but reinvent the wheel. German student Caspar Schmitz has designed a castor with an additional axis that could see your shopping trolleys glide over bumps instead of grinding to an abrupt halt. Also in Caspar's portfolio is the transformable wheel chair, an application of "the transformable wheel", a concept which allows a wheel made of flexible plastic to take on an ellipsoid shape when circumstances require a lower center-of-gravity.

Touchdown! Phoenix spacecraft lands on Mars
Image Gallery (7 images)
May 26, 2008 NASA has announced the successful touchdown of the Phoenix spacecraft on arctic plains in the north of the Red Planet. The completion of the 10 month journey was confirmed with the detection of a radio signal from Phoenix (a signal which takes more than 15 minutes to reach Earth) indicating that it had reached the Martian surface. The spacecraft reached speeds of approximately 12,000 mph before entering the top of the planet's atmosphere and beginning its decent towards a soft touchdown on its three-legs made possible by parachute deployment and finally, the use of controlled thrusters. Launched on August 4, 2007, Phoenix is the sixth lander to touch down on Mars with only five of the 11 previous international attempts having succeeded including the first successful landing of the Viking program in 1976.

Blended-Wing Boeing completes first test flight
Image Gallery (10 images)
July 30, 2007 The traditional airplane shape is well tried and tested, but manufacturers like Boeing are moving beyond the "tube with wings and a tail" design in the push to improve fuel economy and the environmental impact for the next generation of jets. Inspired by "flying wing" designs from earlier decades like 1988's B-2 Stealth bomber, the company has been collaborating with NASA to test the viability of a Blended Wing Body (BWB) aircraft, using a flat, wide body that tapers out to thin wing-tips and aims to strike an effective middle ground between the tube and flying wing designs. A BWB design allows the entire body of the plane to generate lift and reduces drag in comparison to a tube-shaped fuselage - both of which are key factors in reducing fuel usage. The BWB design also provides a much greater cargo and passenger capacity - making it particularly attractive to the military. After months of development, ground testing and wind-tunnel testing, Boeing flew its first BWB prototype last week with the 8.5 per cent scale, 500-pound X-48B aircraft reaching 7500 feet before a successful landing under remote control.

NASA STEREO sees first light
Image Gallery (4 images)
December 21, 2006 NASA's twin Solar Terrestrial Relations Observatories (with appropriate acronym of STEREO) sent back their first images of the sun this week and with them a view into the sun's mounting activity. STEREO utilizes two nearly identical spacecraft on different trajectories to study the most energetic events on the surface and in the lower atmosphere of the Sun, and their travel through interplanetary space. Data from the spacecraft will allow scientists to construct the first ever three-dimensional views of the Sun, providing a new perspective on Coronal Mass Ejections (CMEs). CMEs are violent explosions on the surface of the Sun that can propel up to 10 billion tons of the Sun's atmosphere, at a million miles an hour, out through the corona and into space. Read More
