soup and the aircraft industry has clasped it to its bosom. I have heard the aerospace program talked about for 20 minutes without using a single noun, so I am going to hand out a little sheet of space acronyms. Maybe these will help you from getting snowed by some of our competitors. [Laughter.]

Mr. TEAGUE. Every astronaut has to know every one of these to respond just like that if it's used.

Mr. SMITH. I asked the guys to get me some of the commonly used ones and they came back in with six pages single spaced yesterday. So I cut them down to one page. We try not to use them in a briefing like this but we can't keep them off the charts and I would rather not snow you. In a lot of cases these DDT and E, that means nonrecruiting costs. (Rack St. No.) Thrust Vector Control, that's a gimbled engine. I really should have had a third column on there.

(Slide 25-Introduction) Charlie tells me I don't have much time this morning. I could talk the rest of the day on space shuttle, but I will see what I can do in 20 or 25 minutes. I am sure all of you are familiar after the landing on the moon, the President appointed a task force to determine how the Nation could best proceed in space into the 1970's, and one of their findings was that due to the large increase in launch cost and the cost of payloads that one of the first elements of any continuing space program would have to be a space system, transportation system that materially reduced the cost of a pound of payload in orbit and the space shuttle, of course, is designed to reduce that cost by a factor of about 10.

WHAT CAN THE SPACE SHUTTLE DO?

20804

THE WORK OF EXISTING LAUNCH VEHICLES, AT FAR LOWER COST

RECOVER PAYLOADS IN ORBIT AND RETURN THEM TO EARTH

• RESERVICE AND REPAIR SATELLITES

CARRY CREWS AND SUPPLIES TO SPACE STATIONS

PERFORM FREE-WORLD DEFENSE MISSIONS

• RESCUE CREWS FROM CRIPPLED SPACECRAFT

SERVE AS A FUEL TANKER FOR REUSABLE TUGS

⚫ SERVE AS A LAUNCHING PLATFORM FOR DISTANT EXPEDITIONS

(Slide 26) What can the shuttle do? First of all, because of cost of the shuttle will be amortized over at least a hundred missions-and I personally believe many more than that-if we can get this bird to fly on a hundred missions I believe we can probably get it to fly 500.

(Slide 27) In addition, the new dimension that will be added by the shuttle is the large cargo payload bay that cannot only launch satellites to orbit, it also will permit the refurbishment, the resupply, the retrieval of wornout satellites or malfunctioning satellites and the return to earth for repair and reuse again.

(Slide 28) A second mission is to take crews and supplies to an eventual space laboratory or space station. This is the kind of system we wish we had, of course, for the Skylab. We don't yet. Perhaps something can be done along that line.

SLIDE 29

(Slide 29) A third use of a space shuttle, of course, is now we have the capability with its airline-like readiness,we design this airplane to commercial-type autonomy, readiness requirements, we expect to be able to turn this vehicle around in less than 10 days, we expect to get into space on 24 hours' notice for a rescue mission. In addition, this brings up the possibility of international cooperation.

I know Congressman Teague is very interested in this subject. Dr. Low and Dr. Gilruth have held conversations with the Russians about standardizing the docking hardware, and that looks to be a definite possibility.

(Slide 30) To make the shuttle more versatile, both the Europeans and Air Force are vitally interested in providing the shuttle with an orbit-to-orbit tug which would permit us to take payloads from low earth orbit to the higher orbits, particularly synchronous, and also retrieve these and return them to earth.
