Explorer and some mission space 1958-1959
In 1958, the United States sent its first satellite into space, called the Explorer built by German engineers, being one of the first best-performing satellites sent by the United States at the time.
Pioneer 0 was the first spacecraft sent to the moon by the Americans on August 17, 1958.
Then followed the Soviet Union, which sent a space probe to the moon on September 23, 1958 (Moon E-1 No.1).
The Americans again sent two more probes: Pioneer 1 on October 11, 1958 and Pioneer 2 on November 8, 1958.
The Soviets followed and sent two other space probes into space: Moon E-1 No.2 on October 11, 1958 and Moon E-1 No.3 on December 4, 1958.
All these missions of the Americans and the Soviet Union have failed.
Another failed mission was Pioneer 3 launched on December 6, 1958.
The first successful mission of the month was Moon 1 sent by the Soviet Union which was partially successful but good near the Moon.
And the Americans then had a partial success with Pioneer 4, on March 3, 1959 near the Moon.
Unfortunately, the Americans still postponed the failed Pioneer P-1 missions on September 24, 1959 and the Pioneer P-3.
The Soviet Union also sent Moon E-1A No.1 near the Moon, but it was a failed mission.
But the waters came two successful and extraordinary missions from the Soviet Union.
On September 13, 1959, Moon 2 was the first spacecraft to reach the surface of the Moon (coming from the Soviet Union, and then another success of the Soviet Union was the first photograph of the hidden face of the Moon, on October 6, 1959 by Moon 3 (Union Soviet Union).
