MAVEN uncovers secrets of Martian atmosphere loss

By - December 21, 2014
Mars is regarded as the most Earth-like of the planets in the Solar System, but its atmosphere is only 0.6 percent as dense as Earth's and is constantly leaking what little air it has into space. NASA'S Mars Atmosphere and Volatile Evolution (MAVEN) Mars orbiter is providing new insights into the loss of the Martian atmosphere by discovering how the solar winds penetrate to surprisingly low altitudes.

Curiosity finds active organic chemistry on Mars

By - December 18, 2014 9 Pictures
The hunt for present or past life on Mars got a boost as NASA's Curiosity rover records spikes in atmospheric methane ten times greater than previously measured by the unmanned probe. Though the levels are far below those found on Earth, methane is a key indicator that life may be or may once have been present. In addition, the nuclear-powered explorer has also detected the first confirmed organic compounds in drill samples taken from Martian rocks. Read More

Curiosity landing site may have been a lake

We tend to think that Mars is as dry as a Noel Coward comedy, but it wasn't always like that. At a press conference on Monday, NASA revealed that data from its Curiosity Mars rover indicates that the Gale Crater area that the robotic explorer has been traversing for over two years may once have been a circular lake that filled and refilled over a period of tens of millions of years.

Dawn space probe gets best look yet at Ceres

By - December 7, 2014 13 Pictures
The Dawn spacecraft has lifted the veil on another corner of the Solar System by taking its best image yet of the dwarf planet Ceres. The nine-pixel-wide image was taken from a distance of 740,000 mi (1.2 million km) from Ceres as part of the final calibration of Dawn's science camera as the unmanned probe approaches the 590 mi (950 km) wide planetoid, which it will rendezvous with and orbit in March of next year.

Lockheed Martin begins Insight Mars lander final assembly

By - November 21, 2014
At some point in every project, you stop unpacking the parts and start putting them together. What's true for flat-pack furniture is also true for spacecraft, so Lockheed Martin has begun the Assembly, Test and Launch Operations (ATLO) phase of NASA's INterior exploration using Seismic investigations, geodesy and heat transport (InSight) Mars lander project. Scheduled to launch in 2016, the unmanned InSight probe will be the first deep-drilling mission sent to the Red Planet. Read More

MAVEN uses special radio to relay data from Curiosity Mars rover

By - November 10, 2014 3 Pictures
NASA's Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft is the latest link in the space agency's Martian communications network for keeping in touch with its surface rovers. Last week, the unmanned orbiter carried out a test using a special radio apparatus that allowed it to relay 550 megabits of data from the Curiosity rover to NASA’s Deep Space Network back on Earth.

Synthetic biology could be the key to manned space missions

By - November 6, 2014 2 Pictures
The secret to pulling off long-term manned space missions is biomanufacturing – at least, that's the argument presented by scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) who have used synthetic biology to produce sustainable alternatives to fuel and anti-malaria drugs. Their theory rests on the idea that biological production processes and harnessing of materials at the mission destination could dramatically reduce mass (and hence cost) requirements. Read More

NASA seeks proposals for deep space missions

By - October 31, 2014
NASA is preparing to launch its Orion spacecraft in December and its Space Launch System (SLS) is scheduled to fly by 2018. However, impressive as this is, more is needed if buyer's regret isn't to set in. To avoid this, the space agency is asking for proposals to develop new technologies to send astronauts to the asteroids and Mars using "sustainable, evolvable, multi-use space capabilities."
