| In a rare event, NASA's Mars-orbiting MAVEN spacecraft was forced to perform a previously unplanned manoeuvre this week to avoid a head on collision with red planet's lumpy, crater-filled moon Phobos.
The Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft has been orbiting Mars for just over two years, studying the red planet's upper atmosphere, ionosphere and interactions with the sun and solar wind.
The spacecraft carried out a rocket motor burn that boosted its velocity by 0.4 metres per second.
Although a small correction, it was enough that MAVEN would miss the crater-filled moon by about 2.5 minutes.
This is the first collision avoidance manoeuvre that the MAVEN spacecraft has performed at Mars to steer clear of Phobos.
