If the pressure drops, the soil pressure increases and this leads to subsidence at the ground level. Since exploitation of the Slochteren (Netherlands) gas field started in the late 1960s the ground level over a 250 kmÂ² area has dropped by a current maximum of 30 cm.
Confidence votes 18.5K. There are quite a few tools that the Astronauts use, though for construction and maintenance in space, the Pistol Grip Tool (PGT) is the primary tool of choice. Its predecessor was the Power Ratchet Tool (PRT), originally developed and created for servicing the Hubble Space Telescope.
This also allowed a change in the size of astronauts. Currently the physical requirements for NASA astronauts differ based on the professional tract chosen. From minimum to maximum, the NASA program can accommodate those ranging from just under 5 feet to 6 feet 4 inches in height.For pilot astronauts, (those in charge of operating the spacecraft), height must be between 64 and 76 inches so they can reach all the cockpit controls of the spacecraft.Payload specialists and mission specialist must both be between 58.5 and 76 inches in height.Astronauts must also maintain a healthy weight, proportional to their height. A look at other space programs around the world shows similar requirements.To be accepted into the European Space Agency, astronauts must have a height of 153 to 190 cm or 5 feet 1 inch to 6 feet 2 inches.rom minimum to maximum, the NASA program can accommodate those ranging from just under 5 feet to 6 feet 4 inches in height.
