In all the rocky, inner worlds of the solar system, Fri. The most challenging to explore.
The surface temperature reached a staggering 867 degrees Fahrenheit (464 degrees Celsius) even the highest Tough landlord Can’t Live Longer A new concept called the Calypso Venus Scout calls for the design of a daring new mission: a science investigation 20 miles (32 kilometers) below the bottom of a cloud-carrying balloon.
Welcome to hell
Venus is slightly smaller than our own planet, it has adopted the nickname “Earth twins”. But if Venus is really the twin of the earth, then it is the worst. Despite their similar size The two worlds cannot be different than this. Although the Earth maintains a shaky climate, with a decent environment and liquid water lingering over vast expanses of the ocean, Venus is a nightmare world.

Of Environment Almost all of the carbon dioxide and found on Earth’s sea surface has reached 92 times the pressure. The disturbing atmosphere is so dense that the planet’s surface temperature is the warmest in the inner solar system – even warmer. Mercury, Despite sitting 50% away from our sun
Of all the missions to Venus, only the Soviets attempted a landing with the Venera program. Undeterred by the extreme situation, most of those landlords failed, but some survived enough to send back some quick exposure before they died.
No lander has reached the surface of Venice since Venera 14 in 1982. To date, the only records on our surface have come from those few Soviet probes and occasionally from orbit. Although Venus may be our twin, we know very little about it.
The wind of Venus
Even nearly 40 years after the last Venus mission, we do not have a reliable, long-term investigation technology to survey the terrain of Venus like Mars. What’s more, with all Interest in exploring MarsWith potential human inspection, no one wants to spend money on developing the technology needed for a risky Venus venture.
But there may be another way to do this and it has been referred to as the Calypso Venus Scout, as mentioned. Recently a white paper was posted on the preprint site RXIV.RJ. Calypso is not currently considered by NASA; The author of the paper wrote about it to give a comprehensive knowledge of the decades-long survey, the government’s long-term planning process for planetary science, the current alternatives.
The mission tries to balance Venus’s two challenges: Venus’s surface is just too hot, but the surface is trying to study orbital missions miles and miles, dense, cloud layers interrupting miles, making incredibly difficult to measure precisely.
You have to go into Calypso.
At an altitude of about 20 miles, the dense clouds of Venus become clear. If you can get an investigation below that level, you should have a clear, uninterrupted view of the ground. And although it is still ridiculously hot at altitude, it is not nearly as hot as the surface: relatively blurry 260 F (130 C).
After the arrival of Calypso in Venus, a huge amount Balloon Clouds will be placed in the atmosphere at the top of the layers, keeping them stable at an altitude of about 30 miles (50 kilometers). No new technology is required for temperature and pressure at this altitude and solar panels can provide enough power to the probe.
From this balloon, an excited module will come down, holding the balloon with a teether 10-30 miles (15-30 kilometers) long. The excited module will cry under the clouds and take some pictures, surveying the terrain as the high-altitude wind will blow the balloon around. Then, once the descent module becomes too hot to handle the internal temperature, the module rises to the top of the cloud and returns the data to Earth when the module cools for another round.
Better to see you
On the way up and down, the probe slowly scans the surface of Venus between visible and infrared wavelengths to a possible resolution of a few inches or centimeters. One of the strengths of Calypso is that it will not only be limited to studying a landing site, but will be able to survey a wide range of it. Venetian landscape.
Criticism of understanding Venus for knowing about our own planet. Billions of years ago Venus was really a pair of Earths with liquid water oceans and pleasant atmosphere. A fugitive greenhouse event in Venus, however, evaporated the oceans, allowing carbon dioxide to enter the unchanged atmosphere, and the space was reduced to rubble. Venus became so dry that the plate tectonics completely shut down and its surface remained locked for at least a few million years.
Venus is both a time capsule, providing a glimpse of what the Earth-sized planet was long ago, and Warning story. By studying more Venus with daring missions like Calypso we can better learn what our own destiny might be.
