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.
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.
Looking ahead to future planetary missions, NASA has selected five new science investigations for refinement over the next year. Later, one or two of those missions will be chosen to actually be launched, perhaps as early as 2020. The selections are part of NASA’s Discovery Program, which had requested the proposals in November 2014. Initially, 27 proposals had been submitted, from which the five current finalists were chosen. The five proposals would study Venus, near-Earth objects, an unusual metallic asteroid and Trojan asteroids.
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.
