Storms, engine failures and shipwrecks happen every year. Since 1976, sailors have relied on satellites to know where they are, to steer a safe course and to call for help in emergencies. Satellites also make us smarter. Almost three billion people around the world cannot reach the internet.
For high-accuracy pH measurements, a three-point calibration (pH 4, pH 7, and pH 10) is used. After rinsing with distilled water, the pH probe (electrode) is inserted into the solution until the pH level has stabilized, and the pH meter has correctly matched the pH value of the calibration solution.
Open-ended questions are broad and can be answered in detail (e.g. "What do you think about this product?"), while closed-ended questions are narrow in focus and usually answered with a single word or a pick from limited multiple-choice options (e.g. "Are you satisfied with this product?" → Yes/No/Mostly/Not quite).
The exploration of Pluto began with the arrival of the New Horizons probe in July 2015, though proposals for such a mission had been studied for many decades. There are no plans as yet for a follow-up mission, though follow-up concepts have been studied.
A cryostat is a vessel used to maintain cryogenic temperatures and is categorized as a liquid cryostat (referred to as a dewar) or a conduction-cooled (cryogen-free) cryostat. These vessels are vacuum insulated and are constructed of non-magnetic materials with copper or aluminum thermal shields.automatic probe station
A space probe is a robotic spacecraft that does not orbit Earth, but instead, explores further into outer space. Space probes have different sets of scientific instruments onboard.
A Temperature Transducer is a device that transforms thermal energy into physical quantities including mechanical energy, pressure, and electrical impulses, among other things.
Indycar driver Kenny Bräck (SWE) survived a split-second deceleration of 214 g during a 220‑mph (354‑km/h) crash on lap 188 of the Chevy 500 at Texas Motor Speedway, USA, on 12 October 2003. This is according to data registered in Bräck's in-car [crash violence recording system".
Satellites communicate by using radio waves to send signals to the antennas on the Earth. The antennas then capture those signals and process the information coming from those signals.
The U.S. gyroscopes provide day-to-day attitude control to control the orientation of the station. Russian thrusters are used for attitude control during dynamic events, like spacecraft dockings, and provide attitude control recovery when the gyroscopes reach their control limits.
