Elon Musk's SpaceX released a cool short animation mock up of what a Falcon Heavy launch would look like. The idea is to use 3x the force currently used by Falcon rockets through use of three booster rockets that are re-usable. This will allow for heavier payloads and dramatically improve the chances for a Mars mission.
The launch is scheduled for November, and we will be watching closely to see if this huge milestone can be achieved.
Good luck SpaceX!
