Scientists build spaceships lighter than air to explore Venus – archyde

JAKARTA – Scientists develop a very light space probe to explore the planet Venus and adapt to environments other than planet Earth.

The project proposed by Northrop Grumman in 2014 called Venus Atmospheric maneuverability platform (VAMP) will deploy a probe from Earth to explore the upper atmosphere of Venus.

Constructed like a balloon, the spacecraft will have a weight lighter than air and will be able to explore the clouds of Venus and examine signs of ancient life on the hottest planet in the solar system.

Later this spacecraft will be equipped with software to independently navigate the atmosphere of Venus, developed by scientists from the University of West Virginia.

Start The independent one, Thursday, December 23rd, equipped with hybrid propulsion, the aircraft will use lift and aerodynamic lift to control its altitude. Because the temperature of the planet Venus can reach around 475 degrees Celsius and has melted many probes sent there.

Meanwhile, they collect energy from the sun as a driving force during the day. In addition, the scientists claim that their software optimizes the flight route, taking into account strong winds and solar radiation, and can thus plan flights for the longest period from months to a year.

The software has three main goals: to create a motion planner for the aircraft so that it can be commanded by NASA’s science team, to locate the aircraft in the atmosphere using vehicles and planetary maps, and to coordinate the vehicle for better atmospheric estimates. Condition.

The motion planner should be considered for an optimal energy strategy, because later the spaceship will orbit the Venuvian atmosphere, which on the dark side of the planet will take a long time without light, so the spaceship must have enough energy to survive this period.

This means that both scientists and the science team have information about the wind direction and need to steer the robot in that direction as it uses less energy. All of this must be done without GPS (which requires a satellite network).

More challenges in exploring Venus

It is claimed that there are biological life forms in the acidic clouds of Venus due to the presence of ammonia. Ammonia is made up of hydrogen, but non-biological processes seem unable to reach the extent scientists believe in clouds, suggesting that a biological cause is more likely.

“We know that life can grow in an acidic environment on earth, but nothing is as acidic as the Venus cloud is believed to be. When some ammonia builds up in the cloud, it neutralizes some of the droplets and makes them potentially more habitable, ”said Dr. William Bains, a scientist from Cardiff University.

“There are many other challenges that life must face if it is to live in the clouds of Venus. At first there was hardly any water there, and all life we ​​know needs water. But if there is life, neutralizing the acid will make the cloud a little more habitable than we thought. ”

It is not clear when the project will start, and it is likely that scientists will have found solutions to address ammonia and other challenges by 2023.
