NASA selects future projects to study Mars and MercuryMay 5th, 2009 - 12:36 pm ICT by ANI
Washington, May 5 (ANI): NASA has selected two science investigations that will aid in the interior examination of Mars and probe the tenuous atmosphere of Mercury.
The projects, valued at approximately 38 million dollars, also establish new alliances with the European Space Agency, or ESA.
“The selections will further advance our knowledge of these exciting terrestrial planets,” said Jim Green, director of NASA’s Planetary Division at NASA Headquarters in Washington.
“The international collaboration will create a new chapter in planetary science and provide a strong partnership with the international science community to complement future robotic and human exploration activities,” he added.
The Lander Radio-Science on ExoMars, or LaRa, will use NASA’s Deep Space Network of radio telescopes to track part of ESA’s ExoMars mission.
Scheduled to launch in 2016, the mission consists of a fixed lander and a rover that will roam Mars collecting soil samples for detailed analysis.
Data relayed from the lander back to the network will allow scientists to measure and analyze variations in the length of the day and location of the planet’s rotational axis.
This data will help researchers further dissect the structure of the Red Planet’s interior, including the size of its core.
When combined with the lander’s onboard instruments, the data also may help confirm whether the planet’s interior is still, at least partially, composed of liquid.
The second selection, named Strofio, will employ a unique mass spectrometer.
The instrument will determine the mass of atoms and molecules to reveal the composition of Mercury’s atmosphere.
The investigation will study the atmosphere, which is formed from material ejected from its surface, to reveal the composition of Mercury’s surface.
Strofio will investigate Mercury as a key component of the Italian Space Agency’s suite of science instruments that will fly aboard ESA’s BepiColombo mission.
Scheduled for launch in 2013, the mission is composed of two spacecraft.
Japan will build one spacecraft to study the planet’s magnetic field. ESA will build the other to study Mercury directly. (ANI)
