Tune in tomorrow for the inaugural running of ScienceLive, our new weekly 1-hour live chat where the hottest topics in science get discussed by the top experts, with Science reporters as moderators.
From our sister site ScienceNOW:
Fifty years ago this week, Russian cosmonaut Yuri Gagarin made history by becoming the first human to travel into space. What have we learned about the challenges of space travel in the past half-century? Will a human being ever set foot on Mars? What will space vehicles look like in the coming decades? And with the NASA budget in trouble, which countries will take the lead in the next great space race?
Join us for a live chat on the future of space exploration at 3 p.m. EST on Thursday, 14 April. Space policy guru John Logsdon and space historian James Oberg will be online to answer your questions, and Science's space reporter Yudhijit Bhattacharjee will moderate. You can leave your questions in the comment box below before the chat starts.
Probably best to leave your comments on the ScienceNOW item so they're all in one place.
