• In 2001, Mars Smart Lander: • In 2010, Mars Science Laboratory:<br />
Mars Science Laboratory<br />
• Launch date in 2005<br />
• Peak heat flux of ~170 W/cm 2 (about 1.4<br />
times greater than Pathfinder), laminar<br />
• Asymmetric aeroshell geometry; much<br />
lighter payload (rover); mission “creep”<br />
quickly resulted; 4.05m diam<br />
• Launch date in December 2011 (originally<br />
scheduled for Sept. 2009)<br />
• Peak heat flux of 226 W/cm 2 , fully<br />
turbulent boundary layer before peak<br />
heating<br />
• Symmetric shape; tiled heatshield; rover<br />
much larger than original design;<br />
instrumented heatshield; 4.5m diam<br />
