Question

select the true statements about the exploration of venus. a lander built to survive for an extended period of time on the surface of venus would need to be built to withstand enormous pressure, like a submersible 900 meters below the surface of earths oceans. the united states was the first nation to land a probe on the surface of venus with nasas pioneer venus 2 mission, which touched down in 1978. landers on venus have been able to study the planets seasons by operating for an entire venus year. using radar imaging, nasas magellan orbiter created a topographical map of nearly the entire surface of venus.

Explanation:

1. The surface of Venus has extremely high - pressure conditions similar to those at great ocean depths on Earth, so a lander would need to withstand high pressure.
2. The Soviet Union was the first to land a probe on Venus, not the United States with Pioneer Venus 2.
3. Venusian landers have not operated for an entire Venus year (about 225 Earth - days) due to the harsh environment.
4. NASA's Magellan orbiter used radar imaging to create a near - complete topographical map of Venus.

Answer:

A. A lander built to survive for an extended period of time on the surface of Venus would need to be built to withstand enormous pressure, like a submersible 900 meters below the surface of Earth's oceans.
D. Using radar imaging, NASA's Magellan orbiter created a topographical map of nearly the entire surface of Venus.
