Surveyor 6 (English: Surveyor 6) is moon landing space probe of the sixth plane of the Surveyor plan of the United States of America. It was launched on November 7, 1967 and landed at the central inlet on November 10. I transmit 30,027 pieces of images to the earth in total.

Plan
Surveyor 6 is the sixth plane of the Surveyor plan and is expectation of the fourth plane which made a soft-landing on the surface of the moon by this plan. The image acquisition after the landing, an investigation into abundance of chemical elements in the lunar soil, the acquisition of touchdown dynamics data, the acquisition of data of temperature and the radar reflectance, the erosion experiment of the vernier engine were performed. In addition to an optics device required by constitution basically same as Surveyor 5, a television camera, a small magnet landing leg belonging to it, the alpha dispersion analyser were the same.
It arrived at the surface of the moon on November 10, 1967. The arrival position was 0.49 degrees N, 1.40 degrees W, the central inlet suburbs at a lunar coordinate. All the aims that I planned accomplished it. It was for the success of this mission, and the duty of the Surveyor plan required in Project Apollo was achieved. Went, and the night of the first month was not got from the data which I could use although I was able to communicate on December 14 on November 24, 1967.
The exploration of the lunar soil was carried out using an analyser using a photograph and the background dispersion of the alpha particle. Similar α proton X-ray spectrometer was used for exploration on Mars.
The engine of Surveyor 6 was rebooted as a space technology test in (UTC) at 10:32 on November 17 and lighted it for 2.5 seconds. I was provided, and power of 150lbf in this way appeared about 4m from the surface of the moon. After having moved 2.5m to the west, I made a soft-landing on the moon again. The space machine continued functioning normally.
Devices
Television camera
The television camera was constitution same as approximately five, but a color filter was changed to the inclination filter (). The inclination filter was used as an analyzer to measure a straight line polarization ingredient of the light scattered in by the surface of the moon, and to detect.
I acquired 29914 images before I greeted the first night including during a re-landing after a landing on the surface of the moon on November 24, 1967.
Alpha dispersion surface analyser
The alpha dispersion surface analyser was designed to measure lunar surface main elemental abundance directly. There was a hole of 100mm in diameter at the bottom of the device to irradiate an alpha ray from six alpha source (curium 242) equally, and there were the independent charged particle detector and sample level with two parallelism here. As for the charged particle detector, there were two sensors which detected the energy spectrum of the dispersion alpha particle from the surface of the moon, four sensors which detected the energy spectrum of the proton produced by a lunar material. Each detector assembly was connected to a wave height analyser ().
Whenever an experiment was conducted, the digital electronic devices transmitted a signal to the earth continuously on the compartment of the space machine. Information of all main elemental quantity except hydrogen, helium lithium was included in a spectrum of one of a lunar sample. Curium was collected with a collimator film, and it was scattered by the gilding of the internal base of the sensor head. This became the cause that backgrounds gradually increased, and a heavy elemental sensitivity technology decreased. Because a noise produced one proton analyzer, it will be put out after two days of use.
43-hour data were provided by an analyser in total by November 24 from November 11. The last data were taken four hours before the sunset of the month. However, the sensor head was overturned after having slept by the second takeoff on November 17. The measurement was continued to obtain a proton from the sun and the information of cosmic rays. Therefore, the scientific analysis objective data of the lunar material were provided in 30 hours after the operational start. Of these, the data of 27 hours and 44 minutes were in a state without a noise.
Result
Surveyor 6 became the launched first rocket from the surface of the moon, and the Jet Propulsion Laboratory of Pasadena monitored it. I got the power by a vernier engine of the liquid fuel, and 3m moved from the first landing site. [1]
