Abstract: An aerospace vehicle system, preferably including one or more capsules, and optionally including one or more propulsion modules and/or safety modules. A capsule, preferably including a pressure vessel including a structural frame and one or more windows, and optionally including a cabin. In alternate embodiments, the system can additionally or alternatively function as a terrestrial vehicle, a watercraft, and/or any other suitable vehicle. A method of operation, preferably including operating the aerospace vehicle system in flight, while maintaining a pressure differential between the pressure vessel interior and an environment surrounding the system.

Abstract: Described herein is a method of storing a biological sample, such as a sperm sample, in an elongated container for cryopreservation. Multiple volumes of biological sample may be placed in each elongated container such that each volume of sample is separated from its nearest neighbor by a separation gas. The present invention further relates to an apparatus and method for loading biological samples, such as sperm samples, into an elongated container for cryopreservation of the sample material. The apparatus and method employs drawing the sample into the elongated container such that individual sample volumes are interspaced by gaps of separation gas. This alternating pattern may be created by repeatedly contacting and removing the elongated container from the sample under suction pressure. The apparatus further incorporates the use of a computer to control the volume and number of aliquots as desired. A container according to such methods is also provided.

Abstract: Described herein is a composition that comprises a cryoprotectant; a membrane protectant that stabilizes or assists in stabilization of membranes of sperm; and a free radical scavenger (e.g., a reducing agent, an antioxidant).
