1,7-17 were manned apollo missions
Manned because man has to operate the equipment.
no
The first manned space flight was by the U.s.s,R in the Sputnik.
yes,possible for a manned mission to Mars by 2023
Alvin (DSV-2) is a manned submersible, built by Litton Systems and commissioned in 1964 for the U.S. Navy. It is owned by the U.S. Navy, and currently operated by the Woods Hole Oceanographic Institute.It is tended by and launched from the R/V Atlantis(AOGR-25), which was acquired by the Navy and is under lease to Woods Hole for Alvin's operations.Alvin was named for its chief inspiration and creative developer, oceanographer Allyn Vine.
One advantage of a manned submersible over a human diver is the increased opportunity to observe one's underwater surroundings. Another is their adapatbility, that is the flexibility of their mounted systems and the ability to quickly refit for different types of missions.
In the strict technical definition, no - submersibles are manned/unmanned craft that require surface support vessels to transport them to/from operating areas, and to provide them with umbilical power and service. Submarines are manned vessels that are capable of operating independently without requiring transportation, or tethered/local support.
This toaster is not submersible. The submersible craft glided silently into the fjord.
Osprey class submersible was created in 1989.
The electric toaster is not submersible, for cleaning. Jacques Cousteau is quite famous for having explored the world's oceans from a submersible craft.
150mm means the well diameter is 150mm, and the well of submersible pump is divided into several specifications. If you want to buy a submersible pump go to VIDO, VIDO's submersible pumps are of high quality and are the choice of most people.
Submersible pumps can be applied to many distinct applications, from pumping large solids or grinding solids to smaller sizes, to transferring waste water at large flow rates or high pressures, to simply pumping up water off the floor or the bottom of a tank; depending upon submersible pump design. Some of the more common submersible pumps designed for specific applications include water submersible pumps, sewage submersible pumps, 12 volt submersible pumps, sand submersible pumps, irrigation submersible pumps, and solar submersible pumps. Solar submersible pumps, while not specific to an application, are best used for slow and steady water transference into a holding tank, but may also be used for direct pressurization applications.... that's my answer... shreya :)
In general, yes, a submarine is larger than a submersible. A submersible is usually considered to be a small craft operated from a support vessel.
You can buy a timed switch mounted on the submersible pump. If you want to buy a submersible pump, you can choose VIDO's submersible pump, VIDO's submersible pump is of high quality and is the choice of most people.
Robotic submersibles carry no humans to operate them
The submersible found the Titanic and was used for many research projects. -74
