The origins of the program date back to 1960, when a Pacific white-sided dolphin was acquired for hydrodynamic studies seeking to improve torpedo performance. [1] The aim was to determine whether dolphins had a sophisticated drag-reduction system, but the technology of the day failed to demonstrate that dolphins have any unusual capabilities in this respect.
As the name suggests, the vehicle parachutes into an ocean or other large body of water. Due to its low density and viscosity, water cushions the spacecraft enough that there is no need for a braking rocket to slow the final descent as is the case with Russian and Chinese crewed space capsules or airbags as is the case with the Starliner.

Portal:Cetaceans/Did you know/1 . A Bottlenose Dolphin Breaching the water...dolphins often leap clear of the water when travelling at speed. This is because the density of water is much greater than that of air and they are able to travel faster by leaping out of the water.
It has been reported that freshwater stingrays use water as a tool by manipulating their bodies to direct a flow of water and extract food trapped amongst plants. [166] Prior to laying their eggs on a vertical rock face, male and female whitetail major damselfish clean the site by sand-blasting it. The fish pick up sand in their mouths and spit ...
Scientists trying to understand the hunting behaviors of bottlenose dolphins have come up with a unique solution: fit them with video cameras.
The Navy gets some of its dolphins from the Gulf of Mexico. Military dolphins were used by the U.S. Navy during the First and Second Gulf Wars, [11] and their use dates back to the Vietnam War. [12] About 75 dolphins were in the program circa 2007, [13] and around 70 dolphins and 30 sea lions were reported to be in the program in 2019. [12]
Dolphins do not physically hold their infants but line up in an echelon position with infants swimming beside them. This position creates a change of water flow pattern from the infant which minimizes separation between the mother and infant, but also increases the mother's surface area and creates a drag for the swimmer.
Footage of a pod of dolphins leaping through the air is going viral after it was taken by a ... which shows the marine mammals skimming over the water and bursting out of the water high into the ...
