Our curiousity will lead us outward... Space Exploration

Space exploration is the use of astronomy and space technology to explore outer space. While the exploration of space is carried out mainly by astronomers with telescopes, its physical exploration though is conducted both by unmanned robotic space probes and human spaceflight. Space exploration, like its classical form astronomy, is one of the main sources for space science.

Lunation Matrix

Observe the Moon every night and you'll see its visible sunlit portion gradually change. In phases progressing from New Moon to Full Moon to New Moon again, a lunar cycle or lunation is completed in about 29.5 days. Top left to bottom right, this 7x4 matrix of telescopic images captures the range of lunar phases for 28 consecutive nights, from the evening of July 29 to the morning of August 26, following an almost complete lunation. No image was taken 24 hours or so just after and just before New Moon, when the lunar phase is at best a narrow crescent, close to the Sun and really hard to see. Finding mostly clear Mediterranean skies required an occasional road trip to complete this lunar cycle project, imaging in early evening for the first half and late evening and early morning for the second half of the lunation. Since all the images are registered at the same scale you can use this matrix to track the change in the Moon's apparent size during the single lunation. For extra credit, find the lunar phase that occurred closest to perigee. Tonight: International Observe the Moon Night

Why a spacefan site? About This Site

I've been fascinated by space exploration since a child growing up in the 70s and 80s. NASA's shuttle program was one of my early passions to research and study. Back in the 80s, NASA would send out large information packets to those who requested them through the mail. I requested my fair share growing up and would spend hours pouring through the information that they sent. Today, I am still very much interested in what lies beyond our planet and solar system!
