Robert Frosh: “We are severely lacking in technology and ambition”
In 1977, when NASA began testing the shuttle, the space shuttle did not yet have engines - it was lifted into the air by an airplane, and then it independently planned to the ground. This program was overseen by the then head of NASA, Robert Frosch. He left the agency just a few months before the first shuttle, the Columbia, went into space. Now Frosch is 81 years old, and a replacement for the shuttles has never been invented.
