Study Notes
Venus Overview
- Venus is the second planet from the Sun.
- Venus's surface temperature is 465° degrees Celsius.
- Venus is approximately 40 million kilometers from Earth.
- A one-way trip to Venus would take around 4 months; a round trip, 8 months.
Venus Characteristics
- Venus's surface is mostly gentle plains with large lowlands and highlands (roughly the size of Australia and South America).
- It has mountains, volcanoes, and extensive old lava flows.
Past Missions to Venus
- Magellan: NASA Venus Radar Mapping Mission (1989-1994)
- Pioneer Venus: NASA Orbiter/Probes to Venus (1978-1992)
- Venera: Soviet Venus Missions (1961-1983)
- Mariner 10: NASA Mission to Venus and Mercury (1973-1975)
Proposed Venus Mission
- Objective: Send a rover to Venus to collect surface samples and compare them with Earth samples to discover potential connections between the two planets.
- Landing site: Venus's surface.
- Sample comparison aims: Exploring potential similarities and differences between the two planets, especially given their similar size and composition.
Mission Requirements: Ship
- Heat resistance: The spacecraft must withstand Venus's extreme heat.
- Cloud penetration: The spacecraft must be able to traverse the thick Venusian atmosphere.
- Fuel type: Liquid hydrogen and rocket-grade kerosene.
Mission Requirements: Rover
- Terrain navigation: The rover needs to navigate the volcanic terrain of Venus.
Required Technology
- Camera: For visual data.
- Drill: To collect surface samples.
- Infrared camera: To examine lava flows.
- Radioisotope power system: For power.
- Humidity sensors: To measure atmospheric conditions.
- Small arm (or manipulator): For handling samples and tools.
Venus's Physical Properties
- Gravity: 91% of Earth's gravity.
- Temperature: Hottest planet in our solar system.
- Type: A terrestrial (rocky) planet.
- Atmosphere: Thick atmosphere, trapping heat and leading to extreme temperatures.
- Rotation: Rotates in the opposite direction to Earth and most other planets.
