Using smaller thrusters, the Japanese team successfully performed a burn to correct the spacecraft's course. A subsequent burn in November put Akatsuki into orbit around the planet.
In , Akatsuki spotted another huge "gravity wave" in Venus' atmosphere. The spacecraft still orbits Venus to this day, studying the planet's weather patterns and searching for active volcanoes.
As of at least late , NASA and the Russian Academy of Sciences' Space Research Institute have discussed collaborating on the Venera-D mission , which would include an orbiter, a lander and perhaps a solar-powered airship. This includes a "steampunk" rover that would use old-school levers instead of electronics which would fry in Venus' atmosphere , and a balloon that would check out Venus from low altitudes.
Separately, some NASA researchers have been investigating the possibility of using airships to explore the more temperate regions of Venus' atmosphere. While destinations in our solar system like the moons Enceladus or Titan or even planet Mars are currently the go-to spots to search for signs of extraterrestrial life.
But a breakthrough scientific discovery in suddenly had scientists discussing whether or not it was possible that life could somehow exist in the present-day hellish atmospheres of Venus. Now, scientists think that it is most likely that, billions of years ago, Venus could have been habitable and fairly similar to current-day Earth.
But since then, it has undergone a drastic greenhouse effect that has resulted in Venus' current iteration with scorching surface temperatures and an atmosphere that many describe as "hellish.
However, in , scientists revealed the discovery of a strange chemical in the planet's clouds that some think could be a sign of life: phosphine. Phosphine is a chemical compound that has been seen on Earth as well as Jupiter and Saturn. Scientists think that, on Venus, it could appear as it does on Earth, for very short amounts of time in the planet's atmosphere.
Well, while phosphine exists in strange ways like as rat poison, it has also been spotted alongside groups of certain microorganisms and some scientists think that, on Earth, the compound is actually produced by microbes as they decay chemically.
This has caused some to suspect that, if microbes could, in fact, create phosphine, then perhaps microbes might be responsible for the phosphine in Venus' atmosphere. Since the discovery there have been followup analyses that have made some doubt whether or not the compound is created by microbes, but scientists are continuing to investigate, especially with new missions planned for the planet.

In some ways it is more an opposite of Earth than a twin: Venus spins backward, has a day longer than its year, and lacks any semblance of seasons. It might once have been a habitable ocean world, like Earth, but that was at least a billion years ago.
A runaway greenhouse effect turned all surface water into vapor, which then leaked slowly into space. The present-day surface of volcanic rock is blasted by high temperatures and pressures. The ingredients are all there, or at least, they used to be. By studying why our neighbor world went in such a different direction with regard to habitability, we could find out what could make other worlds right. Temperature, air pressure, and chemistry are much more congenial up high, in those thick, yellow clouds.
The ancient Romans could easily see seven bright objects in the sky: the Sun, the Moon, and the five brightest planets Mercury, Venus, Mars, Jupiter, and Saturn. They named the objects after their most important gods. Venus, the third brightest object after the Sun and Moon, was named after the Roman goddess of love and beauty. Persistent, dark streaks appear.
Scientists are so far unable to explain why these streaks remain stubbornly intact, even amid hurricane-force winds. They also have the odd habit of absorbing ultraviolet radiation. The most likely explanations focus on fine particles, ice crystals, or even a chemical compound called iron chloride. Although it's much less likely, another possibility considered by scientists who study astrobiology is that these streaks could be made up of microbial life, Venus-style.
These handy chemical cloaks would also absorb potentially damaging ultraviolet light and re-radiate it as visible light. There is much, it would seem, that she can teach us. Our nearness to Venus is a matter of perspective. The planet is nearly as big around as Earth — 7, miles 12, kilometers across, versus 7, miles 12, kilometers for Earth.
From Earth, Venus is the brightest object in the night sky after our own Moon. The ancients, therefore, gave it great importance in their cultures, even thinking it was two objects: a morning star and an evening star. At its nearest to Earth, Venus is some 38 million miles about 61 million kilometers distant.
One more trick of perspective: how Venus looks through binoculars or a telescope. The complete cycle, however, new to full, takes days, while our Moon takes just a month. And it was this perspective, the phases of Venus first observed by Galileo through his telescope, that provided the key scientific proof for the Copernican heliocentric nature of the Solar System. Spending a day on Venus would be quite a disorienting experience — that is, if your ship or suit could protect you from temperatures in the range of degrees Fahrenheit Celsius.
Venus today lacks oceans, appears to lack plate tectonics, and has a massive carbon dioxide atmosphere that creates a greenhouse effect that makes the surface a hot hell. Understanding why Venus and Earth became so different will help us understand why Earth evolved as it has and what the range of conditions for similarly sized worlds around other stars may be. The Soviet Union placed several probes on the surface that made simple measurements in the hour or so before the surface heat fried their electronics.
Now imaging radars are widely used to study the earth both from airplanes and from satellites. The technology is mature and relatively low cost. The European selection process tends to be more open than the U. The EnVision mission would address several key questions:. Operating in its primary mode, VenSAR would map almost the entire planet in stereo at a resolution of 27 m. The radar would produce both images the equivalent of images from a camera as well as high resolution measurements of the absolute elevation of the surface to map its topography.
Venus is the second-closest planet to the Sun, orbiting it every The planet is named after Venus, the Roman goddess of love. After the Moon, it is the brightest natural object in the night sky. Uninhabitable due to extremely high atmospheric pressure, extreme heat, lack of water, and atmosphere composed of primarily Carbon Dioxide. Global Warming, and chemical and radiation pollution also rising. No artificial pollution: However due to high Carbon Dioxide levels in atmosphere green house effect causes the average temperatures to be hotter than Mercury's.
