Parker Solar Probe Parker Solar Probe is a planned NASA robotic spacecraft to probe the outer corona of the Sun. It will approach to within 8.5 solar radii to the 'surface' of the Sun. The project was announced in the fiscal 2009 budget year. Johns Hopkins University Applied Physics Laboratory designed and built the spacecraft, which was originally scheduled to launch in 2015. The launch date has since been rescheduled to the summer of 2018. This was the first time a NASA spacecraft was named after a living person

Sensor In the broadest definition, a sensor is an object whose purpose is to detect events or changes in its environment, and then provide a corresponding output. A sensor is a type of transducer; sensors may provide various types of output, but typically use electrical or optical signals.For example, a thermocouple generates a known voltage (the output) in response to its temperature (the environment). sensor's sensitivity indicates how much the sensor's output changes when the input quantity being measured changes. For instance, if the mercury in a thermometer moves 1 cm when the temperature changes by 1 °C, the sensitivity is 1 cm/°C (it is basically the slope Dy/Dx assuming a linear characteristic).

- Once probes could reach space, the two countries started sending probes to fly past the moon and other planets. Mariner 2 was the first probe to study another planet. On Dec. 14, 1962, Mariner 2 flew past the planet Venus. It confirmed that Venus is very hot. A different probe, called Mariner 4, was the first probe to snap a picture of a planet.

- There are three separate temperature probes designed to tell us about air temperatures and temperatures closer to the ground. We have a solar radiometer that measures the radiation coming to the earth from space. Of course, at sea level, a radiometer will tell you about all the stuff in between you and space. But at the top of Mt Everest there isn't much between you and space, so it's a very reliable measure of what the sun's pushing out.

NET160-Chapter 6 Generic term for two devices used together—a tone generator and a tone locator (probe)—to trace cables by sending an electrical signal along a wire at a particular frequency. The tone locator then emits a sound when it distinguished that frequency. Also referred to by the brand name Fox and Hound.

DNA microarray DNA microarray. In spotted microarrays ,the probes are oligonucleotides, cDNA, or small fragments of PCR products that correspond to mRNAs.Each probe contains a different, characteristic sequence that is specific to a different group of genes under study.These probes are then spotted onto glass substrate to form an array.n oligonucleotide microarrays, the probes are short sequences designed to match parts of the sequence of known or predicted open reading frames. Although oligonucleotide probes are often used in spotted microarrays, the term oligonucleotide array most often refers to a specific technique.
