SAN DIEGO - There is never a shortage of sci-fi or outer space types at Comic-Con, but for the first time, a real space agency plans to attend.
"This was an opportunity we just couldn't pass up," said NASA scientist Dr. Tim Green.
Green will be part of a panel that will include former astronaut Buzz Aldrin, the second man to walk on the moon 45 years ago this week.
"When we look out into the audience, we hope that there will be the next generation of explorer out there," Green said.
Aldrin has been more than supportive about a manned mission to Mars.
"We're already there in terms of remotely operated rovers that are exploring the planet," he said. "A manned mission is the next logical step."
The panel discussion at Comic-Con will be held Thursday, the anniversary of when Neil Armstrong, Aldrin and Michael Collins splashed down in the Pacific Ocean after their historic Apollo 11 mission to the moon.
