Jayanta Brahma, a biomedical scientist at Leeds, has climbed the height of Olympus Mons – a peak on Mars and the tallest mountain in the solar system.
He scaled a climbing wall over 5,000 times to reach the virtual summit at 22,000 metres high.
He undertook the challenge to raise money for the Brain Tumour Charity and hopes to hit £1,000.
The charity funds medical research, and gives support to those people affected by brain tumours.
Jayanta started the challenge in September 2016 and reached the summit at the end of May this year.
