VoyForums Announcement: Programming and providing support for this service has been a labor of love since 1997. We are one of the few services online who values our users' privacy, and have never sold your information. We have even fought hard to defend your privacy in legal cases; however, we've done it with almost no financial support -- paying out of pocket to continue providing the service. Due to the issues imposed on us by advertisers, we also stopped hosting most ads on the forums many years ago. We hope you appreciate our efforts.

Subject: Martian gullies Author: Mike [ Next Thread | Previous Thread | Next Message | Previous Message ] Date Posted: 13:31:38 05/25/04 Tue Troy Shinbrot and colleagues of Rutgers University in New Jersey say that Mars's smaller gravity, which is 38% weaker than Earth's, would allow rockfalls to last longer than they do on Earth. So the gullies on Mars that appear to have been carved by flowing water could instead have been created by landslides of dry powdery material; and cause the kind of geological features usually only associated with running water.
