On the anniversary of President Kennedy's speech on the race to the moon, we look at the dramatic advances in U.S. space science, from commercial flights and missions to Mars to the Webb telescope.

During a press conference on Thursday, space agency officials said they were eyeing Sept. 23 or Sept. 27 as possible dates for the launch.

It's one of two new planets that were recently found about 100 light years from Earth, both of which take just days to orbit their own sun.

After a two-year dry spell, Hollywood's summer blockbusters finally busted some blocks this year. Now, the question is how to keep that momentum going.
