Space-based botanical research: a key GS3 Science & Technology topic regarding extraterrestrial agriculture.
Why in news
Researchers revealed that rocket seeds and other seeds kept in the International Space Station (ISS) for six months remained viable despite slower growth rates.
Background
In 2015, ESA astronaut Tim Peake took 2kg of rocket seeds to the ISS for a six-month mission. A subsequent experiment involving 8,600 schools and 600,000 children was led by Royal Holloway, the Royal Horticultural Society, and the UK Space Agency.

Prelims practice question
With reference to the rocket seed experiment on the International Space Station, consider the following statements:
- The seeds remained non-viable after the six-month mission.
- The experiment involved 10,000 schools and 1,000,000 children.
- A total of 2kg of rocket seeds were transported to the ISS in 2015.
Which of the statements given above is/are correct?
- (a)1 only
- (b)2 only
- (c)3 only
- (d)2 and 3 only
Show answer
Answer: (c) 3 only — Statement 3 is correct. Statement 1 is incorrect: The seeds remained viable despite slower growth rates. Statement 2 is incorrect: The experiment involved 8,600 schools and 600,000 children.
For Mains
