Scientists are particularly interested in Saturn's moon Titan because it's one of the few known moons with its own dense atmosphere. Titan's atmosphere is also thought to be very similar to what Earth's atmosphere was a long time ago. By learning about Titan, we'll learn about our own planet.

Study Suggests Spaceflight May Decrease Human Immunity

A NASA-funded study has found that the human body's ability to fight off disease may be decreased by spaceflight. The effect may even linger after an astronaut's return to Earth following long flights. Results of the study were recently published in "Brain, Behavior, and Immunity," and may help researchers better understand the affects of spaceflight on human immune response. They may also provide new insights to ensure the health, safety and performance of International Space Station crewmembers and future spacefarers on extended missions.

Protecting the health of astronauts is vital for the success of human missions in Earth orbit and to distant locations like the Moon and Mars. Understanding the response of terrestrial life to the space environment can tell astrobiologists a great deal about the future of life on Earth and beyond.
