A while back, my NASA contact, Jon, asked how long our space seed will remain viable in a classroom environment. In his answer, Dr. Jim Alston pointed out that if you kept the seeds in a sealed container in a cool place, they could theoretically last a long time. Well, folks, today I have real experimental data to suggest just how long seal space seed can last! Jim received this very unexpected email with pictures attached (see tomatos left and tall tomato plant below):
Hi,
I am a retired NASA technician that was on the LDEF retrieval team in 1990. I later received a package of seeds that were distributed to schools around the country. The
seeds sat in my refrigerator until this spring (2008), and my wife--who usually plants some tomatoes in her flower garden--decided to see if the seeds would germinate. I am happy to report after all these years that they grew and have produced tomatoes. I am attaching pictures to prove it. The seeds were labeled "Canister 4; Layer-A,B,C,& D MIXED." I would be interested to know if these flew or were in the control group.
Thanks and Congratulations,
Charles Bailey
Holy guacamole, friends--those are some pretty old seeds to be sprouting and growing so well! Here's Doc Alston's response about whether these specific seeds orbited the Earth or stayed safely home in our vault as part of the control group, and his calculation of how old they really are:
Charles,
Good to hear from you and the almost-forgotten tomato seed. The seed that you received were flight seed. The seed in each canister was divided into layers, with layer 'A' being toward space. Your packet was a mix of the 4 layers and was used for the elementary school distribution.
The seed were in flight from 1984 to 1990 and had been produced in 1983, so the seed was/is 25 years old. Did you observe anything unusual about the plants or the fruit?
Thanks for sharing.
Jim
Naturally, I've contacted Mr. Bailey to see if he has more stories to tell about his adventures as a NASA technician. Stay tuned!
