- NASA’s Magellan spacecraft, which ended a five-year mission to Venus in 1994, mapped the broiling surface using radar. Magellan saw a land of extreme volcanism. The orbiter saw a relatively young surface, one recently reshaped (in geologic terms), and chains of towering mountains.

May 6, 2019 · On Sep. 15, Magellan began returning high-resolution radar images of Venus’ surface, showing evidence of volcanism, tectonic movement, lava channels and pancake-shaped domes. During the 243-day mapping cycle that ended May 15, 1991, Magellan mapped 83.7% of the planet’s surface with unprecedented resolution, exceeding its pre-mission objective.

The Magellan mission mapped the surface of Venus with radar in the 1990s. The images gave the first global view of what was below Venus’ thick clouds. This radar image aligns with the surface features seen on WISPR images captured by Parker Solar Probe during its third flyby of the planet in July 2020. Credits: Magellan Team/JPL/USGS.
Feb 9, 2022 · In 1975, the Venera 9 lander sent the first tantalizing glimpses of the surface after landing on Venus. Since then, Venus’ surface has been revealed further with radar and infrared instruments, which can peer through the thick clouds by using wavelengths of light invisible to the human eye.
Nov 9, 2017 · How did Venus become a sulfurous inferno, while Earth evolved to become the only known world with life? Although not currently habitable, Venus lies within the Sun’s "Goldilocks zone," and may have been habitable before Earth. Exploring the surface of Venus is difficult because of the intense heat and crushing air pressure. Read More
NASA's Magellan spacecraft used a sophisticated imaging radar to make the most highly detailed maps of Venus ever captured during its four years in orbit around Earth's sister planet from 1990 to 1994. After concluding its radar mapping, Magellan also made global maps of Venus's gravity field.
