![]() What’s most remarkable about the transmitter is it only produces up to 700 watts of power, which is less than a standard kitchen microwave of 800-1000 watts, at 13.9 GHz. The prototype radar consists of a low-power transmitter that was developed by RIS, tested using the GBT, and targeted at the lunar surface, with the radar signals bouncing back and being received by NRAO’s ten 25-meter VLBA antennas. Through their efforts, the GBT, which is currently the world’s largest fully steerable radio telescope, could be home to a next generation, high-power planetary radar system for scientists to use to study the planets, moons, and even asteroids within our very own solar system. But what if we could take high-resolution images of the Moon’s surface from Earth instead of relying on satellites presently in lunar orbit to take them for us?Īnd taking high-resolution images from Earth is precisely what a collaborative team of scientists and engineers from the National Radio Astronomy Observatory (NRAO), Green Bank Observatory (GBO), and Raytheon Intelligence & Space (RIS) have set out to do with the National Science Foundation’s Green Bank Telescope (GBT) and Very Long Baseline Array (VLBA). Essentially, the resolution of the images becomes worse and worse. ![]() ![]() This is because the closer we try to zoom in on its surface, the blurrier, or more pixelated, the images become. But while we can take awesome images of the whole Moon from the Earth, it’s extremely difficult to get close-up images of its surface given the enormous distance we are from our nearest celestial neighbor at 384,400 km (238,855 mi). Whether it’s with their phones or through the wonders of astrophotography, photographing the Moon reminds us about the wonders and awesomeness of the universe. Byrd who represented West Virginia and who pushed the funding of the telescope through Congress.Everyone loves taking pictures of the Moon. The telescope honors the name of the late Senator Robert C. Since October 1, 2016, the telescope has been operated by the newly separated Green Bank Observatory to deal with pending budget cuts. It currently houses seven additional telescopes, and in spite of its somewhat remote location, receives about 40,000 visitors each year, from high school students to PhD candidates to visiting researchers. The telescope’s location has been the site of important radio astronomy telescopes since 1957. The observatory borders National Forest land, and the Allegheny Mountains shield it from some radio interference. The location of the telescope within the Radio Quiet Zone allows for the detection of faint radio-frequency signals from the universe, which man-made signals might otherwise mask. It is situated in the National Radio Quiet Zone, a unique area where authorities limit all radio transmissions to avoid emissions toward the GBT. Byrd Green Bank Telescope (GBT) in Green Bank, West Virginia, US is the world’s largest fully steerable radio telescope.
