The Met Office hosted the NASA led International Space Apps Challenge at the Google Campus in London on the weekend of the 20 – 21 April.

Chris Gerty, from the Open Innovation Programme at NASA was at the London event and thanked the Met Office for making the weekend such a success.

More than 85 people attended the event from across the UK and Europe, making 13 different teams working on challenges over the weekend. See all the pictures from the weekend on our Flickr account.

Two challenges from London will go forward for global judging and these were decided by a panel of three judges, Chris Gerty from NASA, Irini Papadimitriou, Digital Programmes Assistant Manager at the V&A and Phil Evans, Government Services Director at the Met Office.

The two winning challenges from London were People of the Soil and T-10.

People of the Soil developed a low cost digital soil testing kit, web and SMS protocols and a web application to collect and share soil data globally.

T-10 created an app that astronauts can use on the Space Station to alert them to suitable times to photograph specific parts of Earth.

These will now be judged against other winning challenges globally, with winners being announced by NASA in the coming weeks. Follow @spaceappslondon to find out which challenges win NASA’s global judging next month.
