Today, the MESSENGER spacecraft will succumb to the influence of gravity and impact on the surface of Mercury

The Viking program represents a major effort by the United States to explore Mars, with the particular goal of performing experiments on Martian soil to look for possible evidence of life.  Four individual spacecraft were sent to Mars as part of the Viking project, two orbiters and two landers, launched as identical orbiter/lander pairs.  

One of the primary objectives in the Museum’s previous collection surveys has been to identify artifacts which are actively deteriorating and require stabilizing treatments prior to being relocated to the new storage facility at the Steven F. Udvar-Hazy Center in Chantilly, Virginia. These artifacts with active corrosion, mold contamination, hazardous materials, and physical insecurities were set aside for a team of three contract conservators to perform specialized treatments.

The remarkable twin Voyager spacecraft continue to explore the outer reaches of the solar system decades after they completed their surveys of the Outer Planets. 

Here is a riddle: What takes more than 60 locations, 5 years, and 150 scientists to decide? The landing site for the Mars Science Laboratory (MSL) rover Curiosity. Picking the landing site for a spacecraft to land on another planet is always serious business. And the job of finding the best location for Curiosity to set down on Mars was no exception. Curiosity’s mission is geared towards understanding whether Mars could have ever been habitable.

There is a strange looking car parked in the west end of the National Air and Space Museum in downtown Washington, DC. For now, it is only visible behind its security screen from the second floor landing above. From that vantage, the vehicle’s six wheels, robotic arm, mast, and other protrusions are clearly visible. But since this is the Air and Space Museum, it must be more than just a normal car. Soon the barriers will be gone and the public will be able to view the vehicle up close and personal. And what they will see is a model of the next Mars rover, NASA’s 2011 Mars Science Laboratory. The rover, dubbed “Curiosity” will be launched to Mars later this year and will begin its mission to explore whether places on the Red Planet were ever habitable.
