• Which countries have sent spacecraft to Mars this year? How will the Perseverance rover help scientists prepare for sending people to the planet? (Key Details)
The United States, China, and the United Arab Emirates have all launched unmanned spacecraft to Mars this year. The U.S. rover Perseverance will help prepare for NASA’s goal of sending people to Mars in the 2030s by testing five spacesuit materials. Because Mars has an average temperature of -80 degrees Fahrenheit and a thin atmosphere, astronauts will need protection from the cold and radiation.
• How might finding water on the moon affect future space missions? (Cause and Effect)
Finding water on the moon might affect future space missions by allowing spacecraft to refuel there. Water is made up of hydrogen and oxygen, which are important for making rocket fuel. If scientists can figure out a way to make fuel on the moon, astronauts could travel in space for longer periods of time.
• Summarize the section “Search for life on Venus.” (Summarizing)
Scientists recently discovered phosphine in the atmosphere of Venus. The gas is found in the intestines of some animals on Earth and indicates that microorganisms might be living in Venus’s clouds. The New Zealand company Rocket Lab plans to send a spacecraft to Venus in the next few years that will release a probe that will analyze the planet’s atmosphere and send information back to Earth.
