I'll talk about the Shuttle-C in one of my next suggestions to the HSF

now, I've just posted my suggestion #8 for the Human Space Flight Plans Committee and NASA:

"resize the Orion to 4.5 meters and its crew to three astronauts"

The most interesting thing about Shannon's lecture was that the development cost he estimated for the Side-mount concepts were only 6.5 billion. Development of the Ares 1 alone is estimated to cost between 30 and 40 billion. That's really not surprising, IMO, since the Side-mount concept continues to use most of the existing flight structure: the same expendable fuel tanks, the same solid rocket boosters, the same space shuttle main engines.

He also said that the first test flight for the Side-mount could be ready in just 4 and a half years! That means both the shuttle replacement and the heavy lift vehicle could be ready by 2015 if NASA began working on the Side-mount concept in 2010.

This concept saves billions of dollars could enable us to return to the Moon in 2016!

Eventually, I'd like to see the Ares V heavy lifter developed since it could place at least twice as much payload on the lunar surface as the Side-mount heavy lifter, per flight. But right now, I think the Side-mount concept is both the fastest and the cheapest way for humans to return to the Moon and set up a permanent base there.

Destination Moon

glennwsmith said... Very nice, Marcel. This is one of the most beautifully put together, forward-looking, and yet also understated videos which I've yet seen from a major space agency -- and it just goes to show that there's a lot of good material out there if you know where to find it.
