Abstract: In a method of facilitating flight operations, a payload is coupled to a spacecraft via a payload interface. The relative alignment of the payload and the spacecraft is dynamically adjusted (e.g., for thrust alignment) while the payload remains coupled to the spacecraft.

Abstract: A marine containment device is disclosed for containing a marine species. The marine containment device comprises a container defining an interior chamber. An aperture is in the container for inputting and outputting the marine species relative to the interior chamber. A closure door closes the aperture. A hinge pivotably couples the closure door with the container. A first flotation body is coupled to the first side wall and a second flotation body is coupled to the second side wall for providing a positive buoyancy while holding a portion of the body of water and marine species within the chamber when the container defines a horizontal position within the body of water. The rear end defines a linear plane for positioning on the surface and maintaining the container in a vertical position while holding a portion of the body of water and marine species within the chamber.
