Your goal is to aerobrake on Kerbin at the lowest altitude possible and retain enough velocity to get to space. Mission Plan: You will take a rocket into space, then launch a re-entry capsule from this. This craft must perform an aerobraking pass on Kerbin, then return to space. Space for this challenge is defined as the edge of Kerbin's atmosphere - 69,078 meters. This is the point when your re-entry craft must be without thrust. Scoring will be based on the lowest altitude (above sea level) reached by the craft, as recorded by the game altimeter. Restrictions: You may not have any parts that generate lift on your reentry craft - no wings, fins, or control surfaces. Your re-entry craft may not have any parts that generate thrust - no engines, RCS, etc. Mods for readout/autopilot purposes (MechJeb, Engineer, etc.) are allowed in the general category. Aerodynamic mods will have their own category. Positioning mods (hyperedit, etc.) are not permitted. At least one Kerbal must be on board the reentry craft. Scoring: Your base score is your altitude in kilometers squared. Interplanetary: Divide your score by two if you still retain enough speed to escape Kerbin SOI. Interplanetary Impact: Further divide your score by two if you impact your craft on another planet outside Kerbin SOI. Keep in mind - there wouldn't be course adjustments possible, so I'm pretty sure this one's impossible. Safely Home: -100 points for recovering the craft successfully. Extreme Skydiving: -100 points for performing this with just a Kerbal Score Example: passing through atmosphere - periapsis at 40.000 km. This is squared, yielding 1600.000 km. Round to 1600, and add additional points as necessary. Lowest score wins. Requirements: You will need to post the following pictures: -Launchpad (Multiple shots if assembling large vehicles) -Apoapsis/before acceleration -Before entering atmosphere, in re-entry configuration. -Periapsis (probably wreathed in flames). Make sure the game altimeter is visible on this screen. -Exiting atmosphere. Addendum: As noted by Kasuha below, Kerbals may be aerobraked without a craft, provided that a screenshot showing that pack fuel still equals 100.0% is included.
