Last week, Planetaria reported on why NASA should return to Venus, and new technology being developed to help make that happen, especially as in longer-lived landers or rovers. With its extremely hostile conditions, Venus has been much less of a priority in more recent years, at least in terms of surface missions, despite it being Earth’s closest planetary neighbour. But now there may be more impetus towards a new mission – not one that NASA would do alone, but rather a joint mission with Russia, known as Venera-D.
NASA’s Cassini mission may be entering its last several months now, but that doesn’t mean there aren’t any more cool science discoveries to be made. Some amazing new images were just posted of one of Saturn’s tiniest moons, Pan. This small asteroid-like object orbits Saturn within a gap in the rings and so is known as a ring moon. Scientists had a basic idea of what it looked like before, kind of like a walnut in earlier Cassini images, but the new images show it in much more detail and reveal how odd-looking it really is – more like a giant ravioli or dumpling. There have also been some incredible new close-up images of Saturn’s rings, as Cassini continues the Ring-Grazing Orbits phase of its mission. The images reveal intricate details never seen before in the structure of the rings.
The Solar System has been a busy place in recent years, with missions to a diverse range of worlds, from Mars, Jupiter and Saturn to distant Pluto and even comets and asteroids. Most of these have been NASA spacecraft, which continues to lay the path to exploring such distant places. There are, however, some places which have been visited in the past, decades ago, but now are seemingly no longer a priority, such as Uranus and Neptune. But there is another planet which is actually Earth’s closest neighbour, yet was only last visited in the 1970s and 1980s, by American and Soviet spacecraft – Venus.
