Guided entry performance of low ballistic coefficient vehicles at Mars

2012 IEEE Aerospace Conference, 2012
Current Mars entry, descent, and landing technology is near its performance limit and may be unable to land payloads on the surface that exceed 1 metric ton. One option for increasing landed payload mass capability is decreasing the entry vehicle’s hypersonic ballistic coefficient.
