The control panel of the Shuttle on the STS-51-F mission, showing the selection of the Abort-to-Orbit (ATO) option. STS-51-F's first launch attempt on July 12, 1985, was halted with the countdown at T−3 seconds after main engine ignition, when a malfunction of the number two RS-25 coolant valve caused an automatic launch abort.
Common problems with dashpot timers were variations in temperature, the entrance of dirt and other matter into the dashpot system, and general wear and tear of the system. Every kind of dashpot timer has seen use in different technologies, from toasters to automated factory operations. The dashpot timer, or mechanical timer, has changed the way ...
Boeing CST-100 Starliner for OFT-2 Arrives at SLC-41. On 9 December 2020, NASA and Boeing announced that 29 March 2021 was the targeted launch date for the OFT-2 mission. [14] [11] On 16 December 2020, Boeing officials released the official mission patch for the Orbital Flight Test-2 mission.
In orbital mechanics, the Hohmann transfer orbit is an elliptical orbit used to transfer between two circular orbits of different altitudes, in the same plane. The orbital maneuver to perform the Hohmann transfer uses two engine impulses which move a spacecraft onto and off the transfer orbit.

Control valves are normally fitted with actuators and positioners. Pneumatically-actuated globe valves and diaphragm valves are widely used for control purposes in many industries, although quarter-turn types such as (modified) ball and butterfly valves are also used. Control valves can also work with hydraulic actuators (also known as ...
The cam can be seen as a device that converts rotational motion to reciprocating (or sometimes oscillating) motion. [clarification needed] [3] A common example is the camshaft of an automobile, which takes the rotary motion of the engine and converts it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.
The solenoid/diaphragm timer uses more battery power throughout the "on" cycle because the solenoid must be actuated the entire time that the water flow is "on". The ball valve timer using the motor and gear actuator only uses more battery power during the few seconds that motor is used to turn the water flow on or off.
