Falcon 1Carries a hexagonal aluminum alloy chamber as a simulated payload (weight 364 lbs, about five feet long)An elliptical orbit of 500 km by 700 km, 9.2 degrees inclination from the equator First privately launched vehicle to make orbit
Oct. 2, 1608Invention of the TelescopeHans Lipperhey, spectacle-makerMiddelburg, Zeeland, NetherlandsStates General discussed Lipperhey's application for a patent on the telescope on Oct. 2 (denied!)Others also claim to have invented the telescope, but documentation not availableNews of the telescope spread rapidly!

Remember Keplers 3rd Law
p2 = a3
Astronomical Imaging Spacecraft use cameras that measure light intensity only no colorCameras take pictures through colored filtersEach picture is a black & white image of the light intensity at a particular color.Opportunitys view into Victoria Crater on Mars
Astronomy Rules!Astronomyis looking up!
Making Color ImagesMultiple images are taken in different colored filtersImages are combined to produce a color picture
Panchromatic CamerasCamera Mast Assembly on Spirit and OpportunityTwo CCD camerasEach camera contains a filter wheel with filters that pass only specific colors of light
Getting the Colors RightEach rover has a color calibration target From B&W images of the calibration target, image scientists adjust the balance of color in the final, combined image by controlling the brightness of each B&W image when added togetherThe goal is to reproduce what it really looks like
Better eyes than oursThe rover cameras are sensitive to a wider spectrum of light than our eyes can seeCameras include ultraviolet and near-infrared filters to record images at wavelengths we cant seeThese filters enhance contrast for analyzing geological features
Pseudo-ColorBW intensity maps to colorNo relation to true color
