In Situ Measurement
In situ measurement refers to the process of collecting data or making observations directly at the location of interest, without physically removing the sample or object being studied. In the context of space and astronautical engineering, in situ measurement is crucial for understanding the properties and behavior of celestial bodies, such as planets, moons, asteroids, and comets. This type of measurement can be performed by robotic spacecraft, landers, or rovers, which are equipped with various instruments and sensors, such as cameras, spectrometers, magnetometers, and seismometers. In situ measurement can provide valuable information about the composition, structure, atmosphere, magnetic field, gravity, and seismic activity of celestial bodies, which can help scientists and engineers to design and operate space missions, as well as to advance our knowledge of the universe.
