• Pioneer 3 - . Mass: 6.00 kg (13.20 lb). Nation: USA. Agency: NASA. Program: Pioneer. Class: Moon. Type: Lunar probe. Spacecraft: Pioneer 3-4. Decay Date: 1958-12-07 . USAF Sat Cat: 111 . COSPAR: 1958-Theta-1.

  Failed to reach moon; provided radiation data. Pioneer III, the third U.S.-IGY intended lunar probe under the direction of NASA with the Army acting as executive agent, was launched from the Atlantic Missile Range by a Juno II rocket. The primary objective, to place the 12.95 pound scientific payload in the vicinity of the moon, failed. Pioneer III reached an altitude of approximately 70,000 miles and revealed that the earth's radiation belt comprised at least two distinct bands.

• Pioneer 4 - . Mass: 6.00 kg (13.20 lb). Nation: USA. Agency: NASA. Program: Pioneer. Class: Moon. Type: Lunar probe. Spacecraft: Pioneer 3-4. USAF Sat Cat: 113 . COSPAR: 1959-Nu-1.

  The fourth U.S.-IGY lunar probe effort, Pioneer IV, a joint project of the Army Ballistic Missile Agency and Jet Propulsion Laboratory under the direction of NASA, was launched by a Juno II rocket from the Atlantic Missile Range. Intended to impact on the lunar surface, Pioneer IV achieved earth-moon trajectory, passing within 60,200 km of the moon before going into permanent orbit around the sun.

• Jupiter biological test results. - . Nation: USA. Army announced that sea urchin eggs fertilized before Jupiter nose cone flight continued to grow normally..
