#as-207

Planned launch: August 1967

Launch Vehicle: Saturn IB SA-207 and SA-208

Spacecraft: CSM-101 and LM-2

Prime crew:

-Commander: James Alton McDivitt

-Command Module Pilot: David Randolph Scott

-Lunar Module Pilot: Russell Louis "Rusty" Schweickart

Backup crew:

-Commander: Patten "Tom" Stafford CDR

-Command Module Pilot: John Watts Young

-Lunar Module Pilot: Eugene Andrew "Gene" Cernan

The mission number of AS-278, came from Saturn IB AS-207 and AS-208. It was also known as Apollo 3 and was planned as an D-type mission.

"It was planned that McDivitt's crew would conduct the Apollo D mission - a first manned test in earth orbit of the Lunar Module. Separate Saturn IB launches would put Apollo Block II CSM 101 / AS-207 and Lunar Module LM-2 / AS-208 into earth orbit a day later. The crew would then rendezvous and dock with the lunar module and put it through its paces.

When Schirra's Apollo 2 / AS-205 mission was cancelled in November 1966, the booster went to McDivitt's mission, and it was called AS-205/208, or AS-258."

This flight was cancelled due of the Apollo 1 launch pad fire on January 27, 1967. After the fire, it was decided to launch the mission on a single Saturn V as Apollo 9. The prime crew remained the same for Apollo 9 but the backup crew flew as Apollo 10.

"Planned Apollo D mission. Two Saturn IB launches would put Apollo CSM and LM into orbit. CSM crew would dock with LM, test it in earth orbit. Cancelled after Apollo 204 fire.

Before the Apollo 1 fire, it was planned that McDivitt's crew would conduct the Apollo D mission - a first manned test in earth orbit of the Lunar Module. Separate Saturn IB launches would put Apollo Block II CSM 101 / AS-207 and Lunar Module LM-2 / AS-208 into earth orbit. The crew would then rendezvous and dock with the lunar module and put it through its paces. After the fire, it was decided to launch the mission on a single Saturn V as Apollo 9. CSM-101 instead would be used to accomplish the Apollo C mission that Grissom's crew was to have flown.

LM-2 was modified to appear like the Apollo 11 Lunar Module "Eagle," and displayed at the Smithsonian's National Air and Space Museum in Washington DC.

When Schirra's Apollo 2 / AS-205 mission was cancelled in November 1966, the booster went to McDivitt's mission, and it was called AS (or Apollo) 205/208, or AS-258 (before Schirra's cancellation, McDivitt's was AS-278, because it used Saturn IB boosters 207 and 208).
