Would Love To But
The links seem to have gone dead. It's possible NASA has been cleaning house to cover up how bad the current plan is. It appears Guess Zubrin's publisher may have complained about giving half his book away for free on the internet as well. Summaries are available from the Mars insttue at Humans to Mars: A Survey of Mission Scenarios. Read Mars Direct and the NASA reference missions based upon it. I did a search a while back and managed to find some of the old reports, but I don't have the info handy now.
