Growing Green on the Red Planet

Mars mass is 6.4169 x 1023 kg. That is slightly more than 10% of the Earth's mass. Mars is a tiny world in every way when compared to Earth. In our Solar System, Mars is the second smallest planet by mass.

In The Martian, a science fiction book by Andy Weir and a Hollywood movie blockbuster, Mark Watney is stranded on Mars after his fellow NASA astronauts think he died and left the Red Planet without him. Watney is left with space suits and a controlled-environment habitation module (or Hab), but he does not have enough food and water to survive until NASA sends a rescue mission.

Plants In Space – Build an Automatic Plant watering System for Your Mars Soil

Mars presents unique challenges for spacecraft that hope to land on its surface. Its atmosphere is too thin to be very helpful for slowing down, but it's also just thick enough to be a problem. Temperature can vary wildly between day and night, and global dust storms can blot out the sun for weeks at a time.

Students will explore technology used in space through the Arduino tool. They will build an automatic watering system that measures soil humidity and waters a plant accordingly. The basics of programming in C++ will be introduced using the Arduino Integrated Development Environment (IDE) software.

Students Plant Seeds to Help NASA Farm in Space

NASA is seeking plant varieties that could grow best in space, providing food for astronauts to eat on their way to future deep space destinations, including Mars. Teachers and students in South Florida recently began experiments to test a wide spectrum of seeds to see which would flourish in different conditions.

Retired NASA astrophysicist supplying teachers with affordable Space Dirt

A retired NASA astrophysicist from Texas has developed an affordable, scientifically based, Martian and Lunar soil known as regolith simulant (or planetary soil simulant) for teachers and Home School parents to use in the classroom. A regolith simulant is a terrestrial material that educators can use to simulate the chemical and mechanical properties of Martian […]
