History and Timeline of Astrobotany
Discussion and speculation about plants in space has been around since the early 20th century. The Russian astronomer and astrobiology pioneer Gavriil Adrianovich Tikhov was the first to use the term astrobotany.
This paper details a history of astrobotany:
Agriculture for Space: People and Places Paving the Way
1880 – novelist Percy Greg writes Across the Zodiac: an early science fiction story about a space traveler who goes to Mars with plants. This is one of the earliest mentions of plants in space.
1895 – Russian scientist Konstantin Tsiolkovsky speculates about orbital greenhouses in space in “Grezy o Zemle i Nebe” (Dreams of Earth and Sky).
1940-50 – Russian astronomer Gavriil Adrianovich Tikhov defines astrobotany and is appointed head of the USSR Sector of Astrobotany. This is around the time that the term “astrobotany” is first definitively used.
1946 – The first seeds launched on V-2 rockets by the US.
1954 – Jack Myers tests algae for bioregenerative life support systems for the USAF and NASA. This is the beginning of a space agency’s first serious interest in utilizing plants in life support.
1971 – 500 tree seeds are flown around the Moon on Apollo 14. These will be planted on Earth upon their return and are referred to as Moon Trees.
1982 – Soviet cosmonauts grow Arabidopsis onboard Soviet Salyut 7. These are the first plants in produce seeds and flower in space.
1995 – NASA begins using BRIC (Biological Research in Canisters). Arabidopsis will be flown using this hardware.
2014 – Data retrieved from BRIC19 aboard the ISS yields the first ever complete transcriptome RNA sequencing of arabidopsis thaliana, allowing for monitoring of every single gene in arabidopsis.
2016 – Zinnia blooms aboard the International Space Station under the care of U.S. astronaut Scott Kelly.
