What is NASA planning to do in the future?

NASA’s future will continue to be a story of human exploration, technology, and science. NASA engineers will develop new technologies to improve air transport at home and meet the challenges of advanced space exploration. Our scientists will work to increase an understanding of our planet and our place in the universe.

What does H mean in a launch?

4. Liftoff. Liftoff denotes the exact moment when the rocket, with the satellite onboard, begins to leave the launch pad under its own power, beginning its journey to space.
