New Shepard

• About: Reusable rocket system crafted to transport astronauts and research payloads beyond the Karman line.

o Karman line: It is a boundary 62 miles (100 kilometers) above mean sea level that borders end of  Earth's atmosphere and the beginning of space.

o It is a conventional definition of the edge of space. It is not universally accepted.

• The name "New Shepard" is inspired by Alan Shepard, the first American astronaut to travel into space.
• Reusability: New Shepard is a fully reusable rocket system, designed to be launched multiple times without significant refurbishment.
• Environmental Impact: Nearly 99% of New Shepard’s dry mass is reused, including the booster, capsule, engine, landing gear and parachutes. 

o New Shepard’s engine is fuelled by highly-efficient liquid oxygen and hydrogen.

o During flight, the only byproduct is water vapour with no carbon emissions.
