Ranger 1
Failed Earth-orbit test vehicle (USA)Launched: August 23, 1961
Ranger 1 was the first US spacecraft designed to test the feasibility of going into a parking orbit around Earth before heading out to the Moon. A parking orbit would give engineers time to calculate a much more accurate trajectory for the spacecraft to follow to the Moon. Ranger 1 made it into low Earth orbit. Its engines, which were supposed to re-ignite after 13 minutes and burn for 90 seconds, only burned for a few seconds and then shut off. The spacecraft eventually re-entered Earth's atmosphere after completing 111 orbits.
Pioneer P-3
Failed lunar flyby USALaunched: November 26, 1959

Failed lunar impactor (USSR)Launched: January 2, 1959
The spacecraft missed the Moon and went into a solar orbit. However, the spacecraft did provide some scientific data when it released a sodium vapor cloud 70,000 miles from Earth that allowed scientists to study interplanetary gases.
Pioneer 3
Failed lunar flyby (USA)Launched: December 6, 1958
The rocket's first stage shut off early, causing the spacecraft to crash.
Luna 1958C
Failed lunar impactor (USSR)Launched: December 4, 1958
The rocket's first stage failed shortly after launch.
Pioneer 2
Failed lunar orbiter (USA)Launched: November 8, 1958
Just after launch, the second stage of the rocket failed to ignite. As a result, the spacecraft did not achieve orbit and fell back to Earth.
Luna 1958B
Failed lunar impactor (USSR)Launched: October 12, 1958
The rocket carrying the spacecraft to the Moon exploded just after liftoff. Although Luna 1958B was launched hours after Pioneer 1, its trajectory would have allowed it to beat Pioneer 1 to the Moon.
Pioneer 1
Failed lunar orbiter (USA)Launch: October 11, 1958
Just after launch, the rocket's second and third stage failed to separate evenly. As a result, the spacecraft was unable to achieve a lunar trajectory. However, Pioneer 1 did manage to returned data on the Van Allen Belt and micrometeorite impacts before re-entering Earth's atmosphere on Oct. 12, 1958.
Luna 1958A
Failed lunar impactor (USSR)Launch: September 23, 1958
The rocket carrying the spacecraft exploded just after liftoff.
Pioneer 0
Failed lunar orbiter (USA)Launch: August 17, 1958
The first attempt by the United States to fly to the Moon ended just 77 seconds after liftoff when the rocket's first stage exploded.
