As well as keeping their fingers crossed for good weather during next weeks close approach of Mars, astronomers are hoping that the skies will be clear on Mars itself.
During National Astronomy Week - Saturday 23 to Saturday 30 August - observing events will be held across the UK where the public can view Mars through telescopes. It is expected that thousands of people will turn out to see the planet closer than it has been for almost 60,000 years. But its not just our own familiar clouds that could spoil the view. There is a risk that a major dust storm on Mars could wipe out any of the surface details visible on the planet.
Marss orbit round the Sun is not circular, and its distance from the Sun varies by over 20 per cent. So when it is close to the Sun, as it is now, the additional solar heating can whip up dust storms that can cover huge areas. The most severe can cover the entire planet. This happened in 1971, for instance, just as the US Mariner 9 space probe arrived at the planet. Its cameras revealed a barren disc, with no detail at all. Marss atmosphere was filled with fine dust from pole to pole. Observers on Earth confirmed that no details could be seen for a whole month.

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
