RELEASE DATE: 23-Jan-2004 IMAGE FILE NAME: meraBounce1.tif SOURCE FILE NAMES: N/A SUMMARY INFORMATION: Visualization of EDL trajectory superimposed on mosaic of 3 descent images taken during Spirit's landing in Gusev Crater NAME OF SUBMITTER: Andrew E. Johnson INSTITUTION: JPL THEME/TEAM/GROUP: EDL SOL OF OBSERVATION: SOL 1 EARTH DATE OF OBSERVATION: 1/04/04 TITLE OF IMAGE: Press the Brake CAPTION: This computer generated visualization depicts an overhead view of the trajectory the Spirit lander took into Gusev Crater. It also shows velocity vectors that convey how the TIRS/DIMES system reduced the horizontal speed of the lander just before touchdown. The descent to the surface and bouncing along the surface are depicted as a blue line. The steady state horizontal velocity computed by DIMES at Rad rocket fire is depicted as a cyan arrow; the total of steady state and Rad rocket induced horizontal velocity, had TIRS not fired, is indicated with a magenta arrow; and the resultant velocity of the lander after TIRS fired is shown with a yellow arrow. North is indicated by the red tipped arrow in the coordinate axes. EMAIL ADDRESS: aej@jpl.nasa.gov PHONE NUMBER: (818) 354-0357 ADDITIONAL COMMENTS:
