By 1981, the plan was for the spacecraft to launch in 1987 and to use aerobraking to circularize its orbit, whereupon it would be able to generate radar coverage of the entire planet over a period of 126 days. Data transmission rates were 1 Mbit per second, matching the imaging and recording speed.

Space-based radar or spaceborne radar is a radar operating in outer space; orbiting radar is a radar in orbit and Earth orbiting radar is a radar in geocentric orbit. A number of Earth-observing satellites , such as RADARSAT , have employed synthetic aperture radar (SAR) to obtain terrain and land-cover information about the Earth .
The Radar System functioned in three modes: synthetic aperture radar (SAR), altimetry (ALT), and radiometry (RAD). The instrument cycled through the three modes while observing the surface geology, topography, and temperature of Venus using the 3.7-meter parabolic, high-gain antenna and a small fan-beam antenna , located just to the side.
Apollo 9, a complete success, landed in the Atlantic Ocean on March 13 and was followed by Apollo 10, the dress rehearsal for Apollo 11. This photograph, taken by Schweickart, shows Scott performing a stand-up extravehicular activity from the Command Module Gumdrop , seen from the docked LM Spider with the Earth in the background.
RIME, Radar for Icy Moons Exploration (RIME) is a orbiting low frequency radar sounder and altimeter for Jupiter's Icy moons SHARAD , The Mars SHAllow RADar sounder (SHARAD) radar (20 MHz) on the later launched Mars Reconnaissance Orbiter complements MARSIS capabilities.
The Suomi National Polar-orbiting Partnership (Suomi NPP), previously known as the National Polar-orbiting Operational Environmental Satellite System Preparatory Project (NPP) and NPP-Bridge, is a weather satellite operated by the United States National Oceanic and Atmospheric Administration (NOAA). It was launched in 2011 and is currently in ...
Venera 5 (Russian: Венера-5 meaning Venus 5) was a space probe in the Soviet space program Venera for the exploration of Venus.. Venera 5 was launched towards Venus to obtain atmospheric data.
