Mars rover begins 20-storey ascent to ridge top
NASA's Curiosity Mars rover has begun climbing a 65-metre-tall ridge, equalling about 20 storeys. Before the ascent, Curiosity gained about 300 metres in elevation for which it travelled 17.32 kilometres from its landing site to the base of the ridge. Notably, the car-sized rover landed on Mars in 2012 and has sent back over 2 lakh images ever since.
