Last weekend, the SpaceX-7 rocket exploded, along with the RHS's two kg of rocket seeds shortly after take-off. The rocket was unmanned and broke up in the air above Florida.
The project, Rocket Science, will give around half a million UK children the chance to learn how science in space contributes to our knowledge of life on earth, by growing rocket from seeds sent to schools that have been to space to compare to seeds that have spenbt their life on Earth.
The RHS said: "We have already procured more rocket seeds from the same British seed company, Tozer Seeds, and we are working with the UK Space Agency and European Space Agency to get these seeds on one of the next available cargo launches.
"The rest of the project will continue on the same timeline so we will still open up official registrations in September and seeds and resource packs will be sent in spring 2016."
