The scientists are developing algorithms that will be used for spacecraft of the future, heading towards Venus and Jupiter's moon Europa. The main task to be solved in the near future is associated with the descent of spacecraft to the surface of distant planets. Two ideas are being considered today for a safe descent. One is related to the use of a fan, the other is related to accurate calculations for landing.
The space age marked itself with the fact that man was able to set foot on the moon. Now it intends to continue space exploration and visit the Mars and other planets, using the most modern technologies to build ships.
The main course that is set for the near future is the Venus and the Jupiter's icy moon Europa. It is Europe that is theoretically considered as a habitable planet. The engineers are already taking into account the different characteristics of distant planets, presenting the basic requirements for hypothetical spaceships that have a long journey. The Venus is considered a difficult world to visit.
On its surface, very high temperatures and crushing pressure, they destroy all previously sent rovers, which were lucky enough to reach the planet's atmosphere and stay there for at least two hours. The last such case was registered 30 years ago.
It is assumed that in the future, the landing on the Venus may occur in a ridged mountainous area called tessera. It is assumed that landing in this area can be efficient and safe. So says planetary scientist Joshua Niseli from the University of Alaska. He and his colleagues have developed a model for a mission to Venus that could be launched in 2030. It will include three devices, an aerobot - it will be in the cloud zone of the planet, and also a landing module.
It will have to land, and then work on collecting tessera rock samples. According to the calculations of the scientists, these zones are similar to the Earth's strata, under which tectonic plates move. Studying the landscape of the Venus, the scientists rely on data from NASA's Magellan orbiter.
The maps compiled by the satellite suggest that most tesserae are tilted at 30 degrees, and the lander needs to cope with this surface using four telescopic structures. It is extremely important as the apparatus runs the risk of toppling over. Therefore, the descent vehicle requires a certain navigation, which is to be created. If this route is mastered successfully, its basis will be used for landing in Europe.
