Karl Brauer EPD 609 Engineering for Space Title: Challenges for Spacecraft Landing Systems Motivation: Challenge Solution Getting Equipment to the Surface of Other Planets Develop new landing systems Developing New Landing System for a Variety of Terrain Use a Sky-Crane, Legged, or Air-Bag Landing System Land on a Generally Obstruction Free Area Use the Legged Landing System Bounce across Hazardous Terrain Use the Air-Bag Landing System Land on a Mixture of Terrain at a Certain Location Use the Sky-Crane Landing System The System Must be Reliable Use Tested Technology with proven Results Put Larger/Heavier Devices on other Planets Larger Versions of Previous Landers or Develop New Lander Types Landing at an Accurate Location Use a Sky-Crane or other new Landing System One of the major challenges facing the future of space exploration is not in getting to the other planets but in getting onto the other planets from an orbit around them. In recent years there have been many, costly mistakes as the result of landing system failure which have led to the catastrophic failure of the exploration vehicles they were carrying. In order to prevent these failures, there have been new landing systems proposed as well as many improvements to the older legged landing systems which were used on many previous missions. 1 The most difficult part about designing a landing system for another planet is in that there is little known about the actual landing zone. The proposed landing area is often in the hundreds of square kilometers which almost certainly encompasses a huge variety of terrain. What is more, there are not usually maps accurate enough to fill the need. On a landing system with a ground clearance of only 20-30 centimeters, a 50 centimeter tall rock can be disastrous and cause the whole mission to fail if it is hit during the landing procedure. In most places on Earth there are not maps accurate to 50 centimeters and, with no one on the other planets to map them, these kinds of surprises are not uncommon to landing
