More Advanced 100 Year Starship Study Cassini–Huygens Nearly a decade after entering orbit, on April 3, 2014, NASA reported that evidence for a large underground ocean of liquid water on Enceladus, a moon of Saturn, had been found by Cassini. According to scientists, evidence of an underground ocean suggests that Enceladus is one of the most likely places in the Solar System to "host microbial life". On June 30, 2014, NASA celebrated ten years of Cassini exploring Saturn and its moons, highlighting the discovery of water activity on Enceladus among other findings. Overview A summary of Cassini's achievements after a decade in orbit On April 16, 2008, NASA announced a two-year extension of the funding for ground operations of this mission, at which point it was renamed to the Cassini Equinox Mission. This was again extended in February 2010 with the Cassini Solstice Mission. Naming Objectives Huygens' explanation for the aspects of Saturn, Systema Saturnium, 1659. Itinerary History Instruments

Galileo (spacecraft) Galileo was serendipitously positioned to view Comet Shoemaker–Levy 9's impact with Jupiter. These images, taken several seconds apart, show fragment W colliding (1994) Galileo was an unmanned NASA spacecraft which studied the planet Jupiter and its moons, as well as several other solar system bodies. Named after the astronomer Galileo Galilei, it consisted of an orbiter and entry probe. It was launched on October 18, 1989, carried by Space Shuttle Atlantis, on the STS-34 mission. On September 21, 2003, after 14 years in space and 8 years in the Jovian system, Galileo's mission was terminated by sending the orbiter into Jupiter's atmosphere at a speed of over 48 kilometers (30 mi) per second, eliminating the possibility of contaminating local moons with terrestrial bacteria. Galileo launching Galileo shot of Earth's Moon Work on the spacecraft began at JPL in 1977, while the Voyager 1 and 2 missions were still being prepared for launch.

W. M. Keck Observatory Podcasts Wow! Signal - 30th Anniversary Report Introduction The "Wow!" source radio emission entered the receiver of the Big Ear radio telescope at about 11:16 p.m. In this Introduction I will first describe briefly the "Big Ear" radio telescope. The "Big Ear" Radio Telescope Here is an aerial photo of the "Big Ear" radio telescope of the Ohio State University Radio Observatory looking approximately east by northeast. The aerial photo to the right shows a view looking north by northwest. The photo to the left is a view looking almost due west. Each of the above photos was taken in 1995, about 18 years after the occurrence of the "Wow!" Below is a diagram of the design of the Big Ear radio telescope showing the path that a typical incoming radio wave takes from the source to the flat reflector, then to the paraboloidal reflector, and then into the feed horns and electronics. More information can be found about the structures of the "Big Ear", Dr. The Computer Printout The Page Layout Below are two important images. For the strongest Wow!
