Sounds from Space

 

Sounds from Scientific, Meteorological and Commercial Satellites 1957-1961

This part of my audio collection is dedicated to commercial and scientific satellites. I started this separate section when Greg Roberts, ZS1BI in Cape Town, started to convert some of his old recordings from a tape recorder with elastic belt drives to electronic format. Greg is a retired professional astronomer and since 1957 has been actively involved in the tracking of artificial satellites, both by optical and radio means. Click on his picture to the right to get more information about him and his activities.

Vanguard 1
TV-4
1958 Beta 2
#00005
(1958-002B)

This is the oldest man-made satellite which is still in orbit. It is expected to last about another 190 years before it finally decays. This spherical Navy test satellite has a diameter of 16cm and was launched by a Vanguard 3-stage rocket into an elliptical orbit with an inclination of 34,4 degrees, a perigee of 640 km and an apogee of 4020 km. The satellite had 2 power sources: the first transmitter operated from a mercury cell supply and had a life time of 3 weeks. Thanks to the fact that this satellite was the first using solar cells the second transmitter operated 6 years and 3 months. On February 21st 1965 it was declared to be no more recognizable as the signal strength had declined almost to zero. The output power of the transmitters was 100mW (on 108.0 MHz) and 50mW (on 108.3 MHz) respectively. The antenna system was comprised of 6 whip elements each 30cm long. They made one turnstile antenna and a dipole. The telemetry transmitted was the package temperature indicated by the difference between the two transmitter frequencies. Therefore, the recordings were made with the receiver Beat Frequency Oscillator (BFO) turned on in order to produce an audible tone heard in the recordings. Thanks for the audio-file to Roy W0SL.

#00111
(1958-008A)

Pioneer 3 was a spin stabilized spacecraft launched by the U.S. Army Ballistic Missile agency in conjunction with NASA. The spacecraft failed to go past the Moon and into a heliocentric orbit as planned. Instead it reached an altitude of 102360 km before falling back and re-entering Earth's atmosphere. It finally burned up over Africa on December 7th at approximately 19:51 UTC.
The revised spacecraft objectives were to measure radiation in the outer Van Allen belt area using Geiger-Mueller tubes and to test the trigger mechanism for a lunar photographic experiment. A transmitter with a mass of 0.5 kg delivered a phase-modulated signal at a frequency of 960.05 MHz. The total effective radiated power was 0.18 W.

SCORE
Project Score
Chatterbox
#00010
(1958-006A)

Project Score (Signal Communication by Orbiting Relay Equipment) was the first American communications satellite which was launched from Cape Canaveral using an Atlas B missile. The entire rocket was placed into low earth orbit (apogee 1480 km, perigee 177 km).
SCORE was an Advanced Research Project Agency (ARPA) project carried out by the Signal Corps with the Air Force providing the Atlas launching vehicle.
The total weight of the satellite was 3980 kg as it included the rocket, the payload itself had a weight of 68 kg.
The low earth orbit limited the life expectancy of the satellite to only 2 to 3 weeks, thus also limiting opportunities for real­time relay between two ground stations. Therefore, a store­and­forward mode was added by including a tape recorder, which also gave the satellite a worldwide broadcast capability.
There were actually 2 identical communications repeater terminals integrated into the fairing pods of the missile and the spacecraft's body acting as an antenna. The redundancy proved to be a good idea as no modulation was received on the carrier wave from experiment package no. 1 which was transmitting at 150 MHz.
However experiment package no. 2 transmitted on 132 MHz properly : voice and teletype messages were sent and returned in real time, and also from its experiment tape recorder. This tape recorder was loaded with new material 28 times before it finally failed due to battery depletion. The 132 MHz all vacuum tubes transmitter had an 8-W output. An additional tracking beacon operated at 108 MHz.
Project Score's actual performance was nominal with experiment operation for 12 days, planned orbit lifetime 20 days, actual orbit lifetime 35 days.

Score was the world's first satellite to broadcast voice including a Christmas greeting from President Dwight D. Eisenhower. His full message was: "This is the President of the United States speaking. Through the marvels of scientific advance, my voice is coming to you from a satellite circling in outer space. My message is a simple one. Through this unique means I convey to you and all mankind America's wish for peace on earth and good will to men everywhere." The transmission took place on December 19th 1958 at 20:15 UTC on 132.435 MHz.

Explorer 6 was launched by USA from Cape Canaveral on Thor-Able launch vehicle into a highly elliptical orbit with an apogee of 41900 km and a perigee of 237 km. The mission of this small, spheroidal satellite was to study trapped radiation of various energies, galactic cosmic rays, geomagnetism, radio propagation in the upper atmosphere, as well as the flux of micro-meteorites. It also tested a scanning device designed for photographing the earth's cloud cover.
Each experiment except the television scanner had two outputs, digital and analog. A UHF transmitter was used for the digital telemetry and the TV signal. Two VHF transmitters were used to transmit the analog signal. The VHF transmitters were operated continuously. The UHF transmitter was operated for only a few hours each day.
Four solar cell paddles mounted near its equator recharged the storage batteries while in orbit. Only 3 of the paddles were deployed. The expected lifetime was 1 year, the actual operation was 2 months.

#00065
(1960-017A)

This Space Ship Vostok-1K No.3 carried two dogs, Pchelka and Mushka, as well as a television system and other scientific instruments. The flight lasted for one day. The reentry was unsuccessful, because the cabin was burned, precluding successful recovery and destroying the two animals. This recording is from vinyl no. 17 which was included in the Italian Enciclopaedia L置omo e lo spazio (The man and the space) issued 1965 by Fratelli Fabbri.

Explorer 9
Explorer IX
S 56A
#00081
(1961-004A)

Explorer 9 was the first in a series of 3.66 m inflatable spheres to be successfully placed into orbit solely for the determination of atmospheric densities.The two hemispheres of aluminum foil were separated with a gap of Mylar at the spacecraft's equator and served as the antenna. A 136 MHz, 15 mW beacon was carried for tracking purposes, but the beacon failed on the first orbit.

Transit 3B
LOFTI 1
#00087
(1961-007A)

The Transit 3B spacecraft (113kg) was launched together with a secondary satellite LOFTI 1 (26kg). They were supposed to separate after launch but this failed. On the picture to the left you can see LOFTI 1 mounted on top of Transit 3B. The transit 3B satellite was powered by nickel-cadmium batteries charged by 6600 solar cells. The orbit was more elliptical than the planned circular orbit, which shortened the satellite's lifetime to 37 days.

Explorer 11
S 15
#00107
(1961-013A)

Explorer 11, also known as S 15, was launched for the purpose of detecting the sources of high-energy gamma rays. The spin stabilized spacecraft achieved an orbit with an apogee of 1786 km, a perigee of 486 km, a period of 108.1 min, and an inclination of 28.9 deg. Telemetry was provided only in real time by two PM transmitters, since the onboard tape recorder failed at launch.

Transit IV A
Transit 4A
#00116
(1961-015A)

The primary mission of the rather small spacecraft Transit IV A was to serve as one of four operational navigational satellites for use by ships and aircraft. The ground stations knew the satellite orbit data and thus could calculate their position on Earth. Transit 4A was the first satellite using a radioisotope thermoelectric generator (RTG) based on a nuclear power source using Plutonium 238 for testing. Transit 4A tranmitted on 150.00 MHz and 400.00 MHz.

Injun 1
Injun-SR-3
SOLRAD 3
GREB 3
#00117
(1961-015B)

Injun 1 was the first of a series of spacecraft designed and built by the University of Iowa to study the natural and artificial trapped radiation belts, auroras and airglow, and other geophysical phenomena. It transmitted on 136.2 MHz. Injun 1 was launched simultaneously with Transit 4A and Greb 3. Transit 4A successfully separated from Injun 1, but Greb 3 (in the lower picture to the right on top of Injun 1) did not. In the recording below you can thus hear also the interference from the signal of Injun 1 and GREB3.
