Originally a public domain film from NASA, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).
Pioneer 0 (also known as Able 1) was a failed United States space probe that was designed to go into orbit around the Moon, carrying a television camera, a micrometeorite detector and a magnetometer, as part of the first International Geophysical Year (IGY) science payload. It was designed and operated by the Air Force Ballistic Missile Division as the first spacecraft in the Pioneer program and was the first attempted launch beyond Earth orbit by any country, but the rocket failed shortly after launch. The probe was intended to be called Pioneer (or Pioneer 1), but the launch failure precluded that name…
The spacecraft consisted of a thin cylindrical midsection with a squat truncated cone frustum of 16.5 cm (6 in) high on each side. The cylinder was 74 cm (29 in) in diameter and the height from the top of one cone to the top of the opposite cone was 76 cm. Along the axis of the spacecraft and protruding from the end of the lower cone was a 11 kg (24 lb) solid propellant injection rocket and rocket case, which formed the main structural member of the spacecraft. Eight small low-thrust solid propellant velocity adjustment rockets were mounted on the end of the upper cone in a ring assembly which could be jettisoned after use. A magnetic dipole antenna also protruded from the top of the upper cone. The shell was composed of laminated plastic and was painted with a pattern of dark and light stripes to help regulate temperature.

A search-coil magnetometer with nonlinear amplifier to measure the Earth’s, Moon’s and interplanetary magnetic field. At the time it was not known whether the Moon had a magnetic field or not.
The spacecraft was powered by nickel-cadmium batteries for ignition of the rockets, silver cell batteries for the television system, and mercury batteries for the remaining circuits… The spacecraft was to be spin-stabilized at 1.8 revolutions per second, the spin direction approximately perpendicular to the geomagnetic meridian planes of the trajectory.
Launch and failure
Pioneer 0 was launched on Thor missile number 127 at 12:18:00 GMT on 17 August 1958 by the Air Force Ballistic Missile Division, only 4 minutes after the scheduled launch time. It was destroyed by an explosion of the first stage of the Thor booster, 73.6 seconds after lift-off at 15.2 km altitude, 16 km downrange over the Atlantic Ocean. The failure was suspected to be due to a turbopump bearing that came loose, causing the liquid oxygen pump to stop. The abrupt loss of thrust caused the Thor to lose attitude control and pitch downward, which caused the LOX tank to rupture from aerodynamic loads and resulting in complete destruction of the launch vehicle. Erratic telemetry signals were received from the payload and upper stages for 123 seconds after the explosion, and the upper stages were tracked to impact in the ocean. The original plan was for the spacecraft to travel for 2.6 days to the Moon at which time a TX-8-6 solid-propellant motor would fire to put it into a 29,000 km lunar orbit which was to nominally last for about two weeks. Air Force officials stated that they were not surprised at the failure, adding that “it would have been more of a shock had the mission succeeded”.
It was the only mission in the Project Able-1 Probes (USAF) entirely run by the Air Force Ballistic Missile Division, as subsequent missions were conducted by NASA…
