cool Idea to rely on solar power as a primary source on Mars :-)

Well, it's since the beginning that you can only research one artefact. BUT there is a little bug. You are 'cleared' for the next artefact about one minute before the current one ends. so when you have several research centers you can have more than one artefact beeing researched but it only works as long as you feed the centers fast enough ;-)
