For today, here are two fictional Youtube videos on what it would be like for astronauts to walk on the surfaces of Venus and Pluto. The clips are modified, taken from the 2004 BBC TV series, Space Odyssey: Voyage To The Planets. This award-winning, fake-umentary series speculated on what a manned exploration of the solar system would be like:
I don't know how long the links will last, but the series is up in parts on Youtube and another link is on Vimeo:Five astronauts pilot the nuclear thermal rocket powered Pegasus spacecraft on a tour of the solar system. Their mission is a collaboration of the NASA, CSA, ESA and РКА space agencies and takes the crew to Venus, Mars, a close flyby of the Sun, Jupiter’s moon[s] Io and Europa, Saturn, Pluto, and the fictional Comet Yano-Moore. Most of the planetary destinations the crew reaches are followed by a manned landing there. Prior to the mission large tanks of hydrogen were deposited in stable orbits around the planets to allow the crew to refuel to have sufficient delta-v for the multi-year mission.The crew encounter many hardships and disappointments along the way. A Venus EVA that almost ends in disaster when the lander Orpheus encounters launch delays, the near-loss of the shield during the aerobrake in Jupiter's upper atmosphere and the loss of samples from Jupiter's moon Io all test the crew's resolve. The most devastating blow comes when the ship's medical officer dies of solar radiation-induced lymphoma in Saturn orbit, forcing the crew to decide whether to continue the mission to Pluto, or abort and return to Earth. In the original British release, the crew decides to press on to Pluto, making history. The American version, broadcast on The Science Channel, was trimmed for length, the crew deciding to turn back at this stage rather than continue. The programme is narrated by David Suchet.

The Youtuber who posted the Venusian clip argues:
Theoretically , we can build VENUS SPACE SUIT. "Chief Navy Diver Daniel Jackson (US Navy) holds the depth record using an ADS. On August 1, 2006 he was submerged at 2,000 feet (610 m) deep off the coast of La Jolla, California." Venusian pressure is an equivalent to a 1-km-deep water ocean. Pressure isn't even the biggest problem , the biggest problem is temperature and acid in atmosphere. But if we landed on the highest mountain Maxwell Montes, conditions would be much more better: pressure - equivalent to a approx. 325 m(!) in ocean , temp. 650 F (+343 C). We can create suits made of titanium [melting point is more than 1,650 °C or 3,000 °F] and use basalt-based fiber technology with a thermal range of -260 C to +982 C (1800 F) and melt point of 1450 C . The biggest problem is to create corrosion resistant coating and effective cooling system.
Caption for the above video: "Venus is the second planet from the Sun, orbiting it every 224.7 Earth days. The CO2-rich atmosphere, along with thick clouds of sulfur dioxide, generates the strongest greenhouse effect in the Solar System, creating surface temperatures of over 460 °C (860 °F). Venus has an extremely dense atmosphere, the atmospheric mass is 93 times that of Earth's atmosphere while the pressure at the planet's surface is about a pressure equivalent to that at a depth of nearly 1 kilometer under Earth's oceans."
