It's also a bit out-of-date, since it seems to have been ignorant of the EDL systems of Mars rovers.

RE: Making expensive craters on Mars
Um, it did have mentions of the latest two sucessful rovers (Opportunity and Sojourner), just not well labelled. There's a graph or two in there with unlabelled axes also...sigh. Beta as the ballistic coefficient, fine. I really liked the plots where, with L/D ratios of about 0.5 or so, you have to dip below zero altitude before climbing back out. I guess they are promoting areolith-braking now instead of aero-braking.
Ok - a little explanation: Ares is the (greek?) name for Mars, thus areolith for rock/dirt on mars, regolith for lunar rocks/soils...right, stupid joke.
I didn't even see the IEEE as the recipient though, until you mentioned it. What the heck is an obvious AIAA (if not SAE) paper doing in an electronics journal? I knew the IEEE was trying hard to be the Wal-Mart of Engineering Journals, but this is ridiculous.
