Beta Regio is a region of rifting and volcanism on Venus. With the evolution of the 37m telescope away from a user facility in the mid-1990s, NEROC interest focused more on very long baseline interferometry, development of radio arrays, and educational activities. El Gran Telescopio Milimtrico Mediante esta tcnica interferomtrica se pueden estudiar las zonas centrales de los ncleos activos de galaxias, cerca de la singularidad central. The maps show the jet and counter-jet of CygnusA The region including the Aristarchus Plateau and Montes Harbinger is probably the most diverse, geologically, of any area of comparble size on the Moon. The first area concerns the choice of interface to the controlling minicom- puter and the second area concerns the implementation of the correlator module.

NEROC Haystack Observatory Undergraduate Research Educational Initiative Small Radio Telescope. Harvard College Observatory, a leading center of United States meteor research, attempt-ed state-of-the-art optical studies of meteors with the Super Schmidt camera, but the first one was not operational until May 1951, at Las Cruces, New MexicoA9 Radar astronomers thus attempted to accomplish what optical methods had failed to achieve. Therefore, 28 modules are necessary to complete a full one-baseline processor and 84 modules Show others and affiliations. terrestrial planets, we are currently collaborating with investigators at NEROC Haystack Observatory, MIT and the Jet Propulsion Laboratory in the analysis of existing 3.8 and 70 cm radar images of the moon, and in the acquisition of new data for selected lunar tar- gets. NRAO's studies indicate that a spectral-domain ("FX") correlator concept can lead to a much less expensive and technically superior correlator as compared to the conventional lag correlator. Typical data are net gains at 1.8"K bath temperature in excess of 30 dB over a tunable range of 20 to 24 GHz with 18-MHz instantaneous bandwidth.
