In what may be a significant step toward the seemingly far-off goal of sending a rover to the surface of Venus, NASA has awarded two grants totalling $245,000 to a semiconductor technology firm to design complex integrated circuits which could withstand the extremely harsh environment on this neighboring world.
With so much attention now on the rovers and spacecraft at Mars, Saturn, Ceres, comet 67P/Churyumov-Gerasimenko, and, soon, Pluto, it may seem like Earth’s closest planetary neighbor Venus has been forgotten again. But no, Venus is still very much on the minds of researchers who are busy developing a concept airplane which could cruise for years in the hellish planet’s atmosphere.
Venus has a reputation for being one of the most inhospitable places in the solar system, and deservedly so. Its thick carbon dioxide (and acidic) atmosphere has a crushing pressure similar to that in the deepest oceans on Earth and the scorching temperature on the surface is hot enough to melt lead. It’s like that everywhere on the planet, all the time. It has therefore been considered an extremely unlikely environment to support any kind of life. Even the toughest microbes here would find survival next to impossible. There is however a possibility, even if remote, that the upper atmosphere of this hellish world could be habitable, according to some scientists.
The Cassini spacecraft has been orbiting Saturn for a long time now, taking stunning images of the giant planet and its rings and moons. Some new images, released today, show a different world though, far across the solar system and much closer to the sun -Venus.
When you think of Venus, the image that comes to mind is that of a sweltering hot hell-hole, which is basically true. With temperatures on the surface hot enough to melt lead and crushing atmospheric pressure, it is not the kind of place you’d want to …
