What data was received?[edit]

The article is crying out for information on what data was received. Pictures? Sensor data of any kind? A bunch of beeps? Comet Tuttle (talk) 00:29, 19 December 2009 (UTC)[reply]

Temperature. They should have got back some pressure data as well but apparently there was a fault with the probe that meant it stuck on transmitting temperature.©Geni 00:55, 20 September 2012 (UTC)[reply]

However, according to this site, the probe for 53 minutes transferred to Earth informations, including for about 20 minutes from the surface. Measured temperature at the surface of Venus was 475 °C (887 °F) ° ± 20 ° C and also the pressure was 90 ± 15 atmospheres. Jirka.h23 (talk) 08:52, 15 February 2016 (UTC)[reply]

Untitled[edit]

Indeed, this is an absolute crying shame. The first device created by humankind to land on and collect data about the surface of an extraterrestrial planet, and the article describing it is a stub? Unbelievable. There seems to be a little more information about this craft on the page for the Venera program as a whole, if that information is well cited, perhaps it could be integrated here. Alas... I wish I knew of a website with good, comprehensive documentation of everything known about the Soviet Space Program. Perhaps more of it than I'd like has simply been lost to history... 199.111.235.152 (talk) 07:02, 23 February 2012 (UTC)[reply]

What looks like one of the original papers[edit]

Doesn't contain much not already in the article but might be worth trying to include at some point.©Geni (talk) 03:26, 6 September 2019 (UTC)[reply]

Conflicting sources on instruments[edit]

First the interplantry bus. Soviet Robots in the Solar System says only a solar wind charged particle collector was carried. NASA says solar wind detector and a cosmic ray detector.[1]

Second the lander the paper above only mentions temperature and pressure sensors. Soviet Robots in the Solar System and Don Mitchell say radar altimeter and Don Mitchell makes a good case for there being one. Soviet Robots in the Solar System appears to be alone in claiming there was a Gamma-ray spectrometer.©Geni (talk) 02:27, 10 September 2019 (UTC)[reply]

Looks like Handbook of Soviet Lunar and Planetary Exploration may have useful information, if you can get a copy from a library. Russian Space Web is a good source for this type of information, but does not have what you are looking for. Siddiqi is a great resource, and on page 81 says the bus had a solar wind detector and a cosmic ray detector; the lander had a resistance thermometer and an aneroid barometer. Could be what you are looking for? Kees08 (Talk) 05:31, 10 September 2019 (UTC)[reply]

Hmm Handbook of Soviet Lunar and Planetary Exploration was published in 1979 so unlikely to differ much from the paper above. Looking at the overall design of the thing I think we can rule out the Gamma-ray spectrometer but the radar altimeter is visible in pictures. NASA is at least consistent on the cosmic ray detector. Hmm further digging bring up a paper called "Measurement of cosmic ray intensity at the Venera-7 interplanetary space probe" published in Kosmicheskie Issledovaniya in 1972 (doesn't appear to have been translated mind and I don't speak russian). So yeah looks like the cosmic ray detector existed.©Geni (talk) 16:26, 10 September 2019 (UTC)[reply]

This paper analyzes data from the Venera 7 mission, nothing on cosmic rays though (could be useful as a source for temperature/pressure information). Didn't really find anything useful on cosmic rays. Kees08 (Talk) 04:53, 11 September 2019 (UTC)[reply]

typo 53 years v minutes[edit]

The probe operated for 53 minutes on the surface, not 53 years as described in summary info box 98.97.118.124 (talk) 18:31, 20 February 2024 (UTC)[reply]

Seal[edit]

The “seal” doesn’t look like a seal and instead looks like a post stamp. AdmiralDoorKnob (talk) 13:27, 29 February 2024 (UTC)[reply]
