Descrizione dell’articolo da parte del venditore

Format is approximately 5 inches by 5.25 inches, single sheet, printed on one side only. This starts with the following excerpt from the New York Times "The United States' spacecraft Ranger IV crashed into the moon today after a flight of just under sixty-four hours." This is then followed by a poem by Sec, which reads Twinkle, twinkle, little fool, On the dark side of the Moon! Muted, man's imperfect tool Cannot answer to his tune; Cannot tell what now it sees On the cruel cratered waste, Cannon count the galaxies Or describe the lunar taste.; There it sits, the heaven-sent, Straddling the solitude, Unresponsive instrument Of a weird and weightless brood; Who will find it there some day Glittering in some abyss, And discover in what way calculations came to this. The Reporter was an American biweekly news magazine published in New York City from 1949 through 1968. The Reporter had a huge influence in its day, both among policy makers and the educated public. One author, writing in Commentary in 1960, praised The Reporter as "represent[ing] the concerns of intelligent American liberalism." In a 1962 survey of reporters asking what magazines they cited in their work, The Reporter came in fourth place after Time, U.S. News & World Report, and Newsweek, with no other publication coming close. Ranger 4 was a spacecraft of the Ranger program, launched in 1962. It was designed to transmit pictures of the lunar surface to Earth stations during a period of 10 minutes of flight prior to crashing upon the Moon, to rough-land a seismometer capsule on the Moon, to collect gamma-ray data in flight, to study radar reflectivity of the lunar surface, and to continue testing of the Ranger program for development of lunar and interplanetary spacecraft. An onboard computer failure caused failure of the deployment of the solar panels and navigation systems; as a result the spacecraft crashed on the far side of the Moon without returning any scientific data. It was the first spacecraft of the United States to reach another celestial body. After launch it was apparent that something was seriously amiss when tracking stations picked up Ranger 4's radio transmitter, but there was no telemetry data being returned or any response when commands were sent to the computer. Without telemetry, it could not be confirmed that the probe's solar panels had unfolded, but the fluctuating radio transponder indicated that Ranger 4 was tumbling and that the solar panels and high-gain antenna were not deployed either. The Atlas and Agena had both performed perfectly, in fact so well that Ranger 4 would not even need a midcourse correction burn to impact the Moon. However, this was all futile if the spacecraft was inoperative. Ground controllers sent commands to the probe to unfurl the solar panels and high-gain antenna and manually use the attitude control system to stop the rolling motion it was in, but the probe was unresponsive. The Spacecraft Data Analysis Team at JPL concluded that the main timer in Ranger 4's computer had stopped, which disabled the telemetry system, preprogrammed events such as solar panel deployment, and also made the probe completely unresponsive to manual commands. Even though lunar impact would occur as planned, the mission was for all intents and purposes a failure. Making it a more bitter pill to swallow was the nearly-flawless launch vehicle performance. Single sheet, printed on one side.
