Conquest of Space is
an attempt to realistically envision the future of space exploration (following the success of Destination Moon, which covered somewhat similar ground). It is the near future (by the standards of 1955, anyway), and a massive
wheel-shaped station has been constructed in orbit around the Earth. A team of astronauts
stationed aboard have been hard at work putting together a rocket for an
unclear purpose. When it is revealed that the spaceship has been constructed
for the first mission to Mars, a small group of volunteers is assembled and they set off. However problems arise as the commander begins to let his religious beliefs get the better of him, and he tries to sabotage the mission.
Though they are not always perfect, the visuals are quite
impressive for the time period. The models look great and the effects used to simulate
weightlessness do a thorough job. There are even shots used to create a sense
of disorientation in the viewer which adds a degree of realism to the
environment.
Really, it's the space scenes that are the highlights of the movie. The acting is alright but the real interesting parts are the scenes where we see men working in space and in a weightless environment and the speculation regarding future technology, some of which still holds up alright today. The spacesuits do look a bit different from what is used today but the design looks really good. They kinda look a bit like some of the original LEGO Space sets.
The science is also pretty good, particularly the fact that the characters are consistently weightless for most of the film, barring the scenes on Mars or "The Wheel". Every scene showing otherwise involves the characters wearing magnetic boots, which is an interesting idea that logically makes sense, even if NASA hasn't fully implemented it aboard the International Space Station.
Though the rocket used by the characters is of a conventional design for the time period, the addition of wings and boosters brings up an interesting concept. They explain that the wings are used for entering the atmosphere of Mars, and once landed the central part is shown to rise up and launch as a rocket. In short, the spaceship combines the principles of a rocket and an airplane, using the concept of the former to take off and the latter to land. Though they were somewhat off on its appearance and how it would be used, this movie may have unwittingly predicted the space shuttle.
The brave crew are launched away from"The Wheel" on their trip to Mars. Note the position of the ladder in the middle. A large portion of the film has that back wall appearing to be the floor.

In the above picture, you can see astronauts working while standing on a magnetic platform. Compare that to the famous shot of the Stewardess in Velcro shoes seemingly walking up the side of a wall in 2001: A Space Odyssey.
The idea of building a space station in the shape of a wheel to create artificial gravity still makes sense. Admittedly such a machine might appear differently were it to be built today, but it is still a conceivable accomplishment that has been recognized quite often in science fiction since this film, including one of my all-time favorite movies, 2001: A Space Odyssey.

Of course, it would be dishonest to say that Conquest of Space is not in any way dated. We now
know a lot more about Mars than we did in 1955 and there are several mistakes
in how the planet is depicted. One might note that the real planet is not as red as in the film, and the atmosphere is much thinner. In actuality, the sub-plot about the crew's search for water would have played out differently. Due to the thin atmosphere and cold temperatures precipitation is more or less impossible on Mars (the short version of some complicated science: cold temperatures mean water freezes solid, water becoming solid means it can't turn into gas and evaporate), so the crew would not have been miraculously saved by snowfall as they are in the film. It is also theorized at this point that there is frozen water on the polar ice caps and possibly beneath the planet's surface, so finding water would not have been as much of a problem. A greater concern today might instead be whether the water is safe to drink. However, it should also be made clear that this information was not available back in 1955.
From a sociological standpoint, the militaristic structure of the space program may also appear somewhat jarring for a modern viewer. One must understand that this is simply what made the most sense at the time. This was still a period when the military was overseeing rocketry experiments. It is unlikely that the filmmakers would have known of or anticipated the major issue that changed that. Basically, the army and the air force were competing against each other probably wasting a lot of money and resources, and neither wanted to share. The government got fed up with this and instead formed the civilian organization of NASA specifically for the purposes of space exploration.
The other part about this film that might appear shocking today is the apparent non-existence of female astronauts (especially with the more recent success of Gravity). In addition being made at a time when all astronauts were men largely due to the fact that it was the military overseeing things (though the first female astronaut only happened eight years later, but the first American woman in space did not occur until 1983), this was also at a time when greater gender equality was not widely recognized. As strange as it may sound now it did not make sense at the time for women to be on such a dangerous mission. However, to the film's credit there is some social progress depicted in the future in that the one Japanese member of the crew is treated as an equal to his white comrades.
