0n June 24, 1947, private pilot Kenneth Arnold reported seeing unidentified flying objects flying past Mount Rainer. In a radio interview from June 26, 1947, Arnold described the unidentified flying objects as looking "something like a pie plate that was cut in half with a sort of a convex triangle in the rear."

The crew of Skylab II deployed a collapsible parasol through the small scientific airlock to act as a sunshade. The micrometeorite shield was sheared off during the launch and with it the protection from the sun.

Launched OTD in 1971, the Mariner 9 spacecraft was the first spacecraft to orbit another planet. Taking more than 7,000 pictures, Mariner 9 imaged over 80% of Mars’ surface in its first year, an important step forward in our understanding of the Red Planet.

The Viking spacecraft each had an orbiter and a lander which respectively orbited and landed on Mars. In general spacecraft that go beyond the Moon are robotic because they have to take action to orbit or land on a planet independently since communications from Earth would take too long to be effective. Beyond robotic landing maneuvers, the lander also included an arm with a soil collector on the end. This was used along with automated biology experiments on the interior of the lander to test for indications of life. The Viking landers robotic operations were controlled by a Guidance, Control, and Sequencing Computer (GCSC) which had software written in Fortran.

If anyone out there has more information on the design of the HDC 402 24-bit processors used to build the GCSC or in the software or I/O hardware actually used in the Viking GCSC, I would love to get more details.

On April 20th in 1967, Surveyor 3 landed on the Moon.  Two and a half years later, Apollo 12 landed near Surveyor 3, and astronauts photographed it and brought back parts. See http://terakuhn.weebly.com/landing_system.html for a list of all successful Lunar and Mars landers.
