100xReusable at 550,000 pounds of thrust

1. Hundred launches per engine seems ambitious.

2. Do you know the time between two launches ( for servicing, cooling down )??

3. I didn't know that the first stage had seven engines.

4. Is Blue Origin competing with SpaceX for at least LEO manned flights??

1) Blue Origin hasn't had as many launches as SpaceX so we don't know how reliable their engines are. However the Space Shuttles flew 135 missions without swapping out engines.

2) Blue Origin hasn't stated this. SpaceX says they will have rockets soon which will have zero maintenance. I would assume Blue Origin has the ability to match them.

3) Seven engines is for the still in-development New Glenn rocket..

4) Definitely competing with SpaceX. Although SpaceX seems more ultimately focused on Mars. Both companies are moving towards reusable Saturn V sized rockets.

The Saturn V is huge. Having something this large falling out of the sky and landing is incredible.
