During the mapping cycle 1 (left-looking) radar surface mapping on Venus (September 15, 1990 to May 15, 1991), around 70% of the Venusian surface was mapped by synthetic aperture radar. In cycle 2 (right-looking), 54.5% of the surface was mapped, mainly the south pole regions and gaps from cycle 1 during May 15, 1991 to January 14, 1992.
Venus Orbiting Imaging Radar (VOIR; also called Venus Orbital Imaging Radar) was a planned 1983 U.S. spacecraft mission to Venus that was primarily intended to use a microwave imaging radar to perform mapping of the Venusian surface.
Radar mosaic of two pancake domes in Venus's Eistla region—both 65 km (40 mi) wide and less than 1 km (0.62 mi) high. Much of the Venusian surface appears to have been shaped by volcanic activity. Venus has several times as many volcanoes as Earth, and it has 167 large volcanoes that are over 100 km (60 mi) across.
Venera 13 provided the first color images and X-ray fluorescence data of the surface of the planet. After analyzing the radar images returned from Venera 15 and 16, it was concluded that the ridges and grooves on the surface of Venus were the result of tectonic deformations. [18] This was found by radar imaging while in orbit.
Magellan's global radar map currently remains as the most detailed Venus map in existence, although the upcoming NASA VERITAS and Roskosmos Venera-D probes will carry a radar that can achieve a much higher resolution compared to the radar used by Magellan. Both probes are expected to launch in 2029.
Dickinson crater is located at 74.6 degrees north latitude and 177.2 east longitude, in the northeastern Atalanta Region of Venus.It is 69 kilometers (43 mi) in diameter. The crater is complex, characterized by a partial central ring and a floor flooded by radar-dark and radar-bright materia
In 1978, the space probe Pioneer Venus 1 went into orbit around Venus for the purpose of making radar observations of the Venusian surface. These observations made possible the creation of the first topographic map of the surface of Venus, and confirmed that a point within Maxwell Montes is the highest point above the average level of the ...
VISAR (Venus Interferometric Synthetic Aperture Radar) is designed to generate global data sets for topography (250 m horizontal by 5 m vertical accuracy) and SAR imaging at 30 m resolution with targeted resolution at 15 m (compare to Magellan which had 50 km spatial and 100 m vertical resolution). VERITAS will create the first planetary active ...
