Have humans explored Venus

Answer 1

NASA's manned probes only went as far as the Moon (1969-1972). But satellites have visited the planet, beginning with Mariner 2 in 1962. Between 1970 and 1985, the USSR (Russia) successfully landed ten unmanned Venera probes, which functioned for less than 2 hours each in the extreme heat. The NASA satellite Magellanmapped the planet with radar from 1989 to 1994 and studied various phenomena. The ESA satellite Venus Express has been orbiting the planet since 2006.

Answer 2

Unlikely. Although numerous probes have (semi) successfully landed on Venus and reported back thanks to the Russians and there have also been numerous fly-by and orbital missions by the Americans and Russians; it is extremely doubtful that humans will ever travel to Venus to orbit let alone land there in our lifetime (and probably wont even in the lifetime of our grandchildren).

A manned Venus flyby mission, using cannibalised hardware from the Apollo program was mooted during the end of the 1960's and was planned to launch in late 1973 using a Saturn V to propel 3 men past Venus in a flight lasting approximately a year. Once it was sensibly argued that there is little or no point sending humans to merely orbit anyway (as any work like this can easily be done remotely and a human mission actually hinders things due to cost, size, distance etc.) the plans were shelved permanently.

Although Venus is often referred to as our "sister planet", it is quite an ugly sister. Venus is covered by clouds of sulfuric gas and sulfuric acid droplets and it has the densest atmosphere in the solar system largely comprised of Carbon Dioxide which is partially responsible for the runaway greenhouse effect of the planet (Venus is home to the strongest greenhouse effect in the solar system). This CO2 rich atmosphere coupled with deadly clouds of acidic sulfur dioxide helps create surface temperatures of over 460 °C (860 °F) and a Venusian planet surface actually hotter than that of Mercury. Furthermore, the atmospheric pressure on the surface of Venus is 92 times stronger than that on the surface of Earth meaning an exceptionally strong suit (and indeed landing craft) would need to be worn by any astronaut to avoid being crushed into the size of a sixpence. Venus's relatively small magnetosphere provides very little protection from the suns cosmic radiation thus adding further problems for any space tourists.

In a nutshell, visiting the surface of Venus is roughly equivalent to visiting hell and the required technology to do so and combat these formidable challenges within the confines of any likely mission objectives is currently beyond our reach.

Answer 3

So far no humans have been to Venus. At present we do not have the technology that would allow a person to survive in the environment conditions of Venus.

Answer 4

We have sent unmanned probes to Venus, but no human has gone farther than the moon.

Answer 5

no
