Scientists want NASA to visit Venus before going to Mars

According to foreign media BGR reports,Scientists believe that travel through Venus will benefit future missions to Mars, and flying past Venus will make the spacecraft to Mars consume less energy.NASA has said the earliest manned mission to the red planet could take place in the 1930s.

The researchers say that if they launch at the right time-when mars and venus are in the right position in their orbits around the sun-they can make a human flight to mars. This


The team also believes that due to the close proximity of the manned spacecraft to Venus, the flyby can collect a lot of data about Venus. If manned spacecraft were to collect data nearby, rather than waiting for long trips between Venus hardware and earth's processors, the amount of new information that could be collected by instruments on Venus' surface would be maximized.

The paper explains that:

The ability to fly back and forth to Mars can be enhanced. Since NASA's early manned planetary interplanetary two-way expedition (Empire) and unfavorable manned planet interplanetary two-way expedition (umpire) were developed in the 1960s and early 1970s, flying Venus can reduce the overall energy requirements of opposing Mars missions (Fig. 2) [3-9]. Therefore, the human flyover of Venus is not only a "free" add-on project, but also a useful complement to any rival Mars mission architecture. So if NASA's first Mars mission is an opposite order mission, it is likely to include a Venus flyby as well.

Mars is obviously more interesting for scientists looking for traces of past or present life in the solar system, but it is also a big deal to learn more about other planets, especially those that are our neighbors. If a scientific expedition to Venus would give us one or two things about the planet and save energy all the way to Mars, it would seem like a good choice.
