Apollo 11: One Small Step on the Moon for All Mankind

NASA astronauts Steve Bowen and Warren "Woody" Hoburg are taking a spacewalk on Friday, June 9, to add a new unrolling solar panel to the International Space Station.

Bowen and Hoburg are scheduled to install an International Space Station Roll-Out Solar Array, or IROSA, on today's spacewalk, with a second one to be installed on June 15. The new arrays will increase the power capacity of the orbiting laboratory.

Neil Armstrong and Buzz Aldrin spent more than two hours outside their spacecraft on the Moon. They studied the surface. They collected rocks. After almost a day, they blasted off. They docked with Michael Collins in orbit around the Moon.
