SHEPARD MISSION: SCIENCE & TECHNOLOGY

NEWS: 31st New Shepard Mission, the New Shepard launch vehicle, and the Karman Line

WHAT’S IN THE NEWS?

Blue Origin's 31st New Shepard mission made history with its first all-female crew, successfully completing a sub-orbital spaceflight that crossed the Karman line. The reusable vehicle showcased the company's commitment to expanding commercial space tourism and gender inclusivity in space exploration.

31st New Shepard Mission – Overview

  • Conducted by Blue Origin, a private aerospace company founded by Jeff Bezos.
  • Marked a historic milestone by featuring the first all-female crew with six women on board.
  • Aimed to promote inclusivity in space exploration and inspire future generations of women in STEM fields.
  • The flight lasted approximately 10 minutes and 21 seconds.
  • The vehicle reached an altitude of 106 km, which is above the Karman line, officially entering outer space.
  • Demonstrated the reusability and reliability of the New Shepard system for commercial space tourism.
  • The mission is part of Blue Origin’s broader vision to make space more accessible through repeated, safe sub-orbital flights.

New Shepard Launch Vehicle – Technical Details

  • Named after Alan Shepard, the first American to travel into space in 1961.
  • It is a sub-orbital launch vehicle designed primarily for space tourism and scientific payloads.
  • Utilizes a vertical takeoff and vertical landing (VTVL) configuration, making it reusable.
  • Composed of two main parts:
  • Booster Rocket: Powered by a single BE-3PM liquid hydrogen/liquid oxygen engine. Provides the thrust required to lift the crew capsule past the Karman line.
  • Crew Capsule: Detaches from the booster at apogee, offering a few minutes of weightlessness. Can accommodate up to six passengers, cargo, or a combination of both.
  • Capable of reaching an apogee of 100.5 km, just over the Karman line.
  • After separation:
  • The capsule lands back on Earth using three parachutes and a solid rocket motor to soften the touchdown.
  • The booster autonomously lands vertically on a landing pad close to the launch site.
  • Designed to be fully reusable, reducing the cost of individual missions and increasing launch frequency.

Karman Line – Definition and Importance

  • An imaginary boundary located at an altitude of 100 kilometers (62 miles) above sea level.
  • Internationally accepted as the boundary between Earth’s atmosphere and outer space.
  • Recognized by the Federation Aeronautique Internationale (FAI) and used in aerospace records and treaties.
  • Crossing the Karman line:
  • Officially classifies the flight as a spaceflight.
  • The people on board are recognized as astronauts.
  • Below the Karman line:
  • Aerodynamic forces dominate; flight is governed by air resistance and lift.
  • Aircraft wings generate lift by pushing against relatively denser air.
  • Above the Karman line:
  • The air is too thin for traditional aerodynamic lift.
  • Orbital mechanics and rocket propulsion become necessary to sustain motion.
  • Spacecraft must rely on their own propulsion systems to maneuver and counteract even minimal atmospheric drag.
  • Serves as a technical and symbolic threshold for defining human presence in space.
