NASA will soon launch a unique instrument called Arcstone to improve the quality of data from Earth observation sensors in orbit.
UNN reports with reference to the NASA (National Aeronautics and Space Administration) website.
Details
NASA is preparing to launch Arcstone, an innovative space instrument that will use light reflected from the Moon to calibrate Earth observation sensors.
Currently, orbital sensors are calibrated by comparing collected data with known sources such as the Sun or the Earth's surface. However, the atmosphere introduces variables that can affect accuracy.
Arcstone, by observing the Moon directly from space, is expected to eliminate atmospheric interference. This will allow for more reliable and universal measurements.
Comment
One of the most difficult tasks in remote sensing from space is to achieve the necessary accuracy in calibrating instruments in orbit.
The Moon is an excellent and accessible calibration source outside the Earth's atmosphere. The light reflected from the Moon is extremely stable and can be measured with a very high level of detail.
The goal of Arcstone is to improve the accuracy of lunar calibration to enhance the quality of space remote sensing data for future generations.
Reference
NASA's Arcstone mission will be launched in late June aboard a small CubeSat satellite.
During its planned six-month mission, Arcstone will use a spectrometer – a scientific instrument that measures and analyzes light by separating it into its constituent wavelengths, or spectrum – to measure the spectral reflectance of the Moon.
Recall
The Blue Ghost spacecraft took stunning images of the sunset from the Moon. NASA hopes they will help unravel the mystery of the strange haze first observed on the Moon in the 1960s.
