  • 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!

  • 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

  • Victoria Crater in Color
