Dyna-Soar in space was never to be, for the program was canceled in December 1963. One of reasons was the development of a new type of aerospace plane, the lifting body.

The huge Titan III C vehicle, towering over 150 feet into the air, moves into place on the launch pad. Missile is carried on same railroad car on which its parts were assembled.
Once the solid rockets have lifted Titan III C and it’s payload off the ground, their role is finished. As this sketch shows, when the solids burn out, they separate from the core section. Just before solid burnout, the first-stage liquid propellant engines are ignited to push the spacecraft farther towards space.
Mariner IV determined that Mars’ atmosphere is only 1 to 2 percent of the Earth’s in density. This may mean that future manned spacecraft to Mars must employ the same landing technique – retro rockets – as the ones which will be used by the Apollo lunar ship.

Electrostatic ion-powered five-man spacecraft passing over Mars’ moon Phobos on the way to Mars. One of two “scout cars” will land on the tiny moon and rendezvous with the ship later.

First manned landing on Mars! This Northrop sketch shows how a soft landing on the red planet might look from ground level. A steerable gliding cloverleaf parachute slows the craft down as the retrorockets start to fire. The parachute is then jettisoned, and the retrorockets perform the final maneuver for touchdown. Retrorocket braking was perfected in the 1960’s to provide the soft landings for the Surveyor moon probe.
