I don't think "Dragon" will have a tower either. If their system goes to plan, the Dragon will have eight 120,000 lb thrust side-mounted liquid-fueled engines for abort. As an added bonus they can be used for powered descent in the event of a parachute failure, or as the primary means of deceleration with the parachutes available in the event of an engine failure.

ARTICLE

The article is a little odd in that it shows Dragon performing a powered landing on Mars. But it does not show any way to get back off of the planet. Maybe it's just the supply ship...
