The growth of plants in outer space has elicited much scientific interest.In the late 20th and early 21st century

Plants were often taken into space in low Earth orbit to be grown in a weightless but pressurized controlled environment

Sometimes called space gardens.In the context of human spaceflight

They can be consumed as food and/or provide a refreshing atmosphere.Plants can metabolize carbon dioxide in the air to produce valuable oxygen

And can help control cabin humidity.Growing plants in space may provide a psychological benefit to human spaceflight crews.Usually the plants were part of studies or technical development to further develop space gardens or conduct science experiments.To date plants taken into space have had mostly scientific interest

With only limited contributions to the functionality of the spacecraft

However the Apollo Moon tree project was more or less forestry inspired mission and the trees are part of a country's bicentennial celebration.

Spaced repetition is an evidence-based learning technique that is usually performed with flashcards.Newly introduced and more difficult flashcards are shown more frequently

Space and survival is the idea that the long-term survival of the human species and technological civilization requires the building of a spacefaring civilization that utilizes the resources of outer space

And that not doing this will lead to human extinction.A related observation is that the window of opportunity for doing this may be limited due to the decreasing amount of surplus resources that will be available over time as a result of an ever-growing population.
