−	I met Al Shapard at The Marshall Space Center in Huntsville, Alabama, when he was assigned to the Mercury-Redstone First Man In Space Project in 1967. An Up and Down 60 miles into space shot testing our spacecraft, rocket and recovery systems. I shown Al his rocket “ride” for that flight. Al had recovered from an ailment and was assigned a new mission this time to the Moon on broad the Apollo 14. His mission this time was call “Moon Trees.”

−	The mission on this day in 1971, Apollo 14 astronauts Alan Shepard, Jr., Stuart Roosa and Edgar Mitchell returned to Earth, splashing down in the Pacific Ocean at 21:05 UT (4:05 p.m. EST). They were recovered by the USS New Orleans, and returned to the U.S. by way of American Samoa. But the three men weren’t the only living creatures to come back from the Moon on Feb. 9, 1971… in fact, human astronauts were in the minority that day. Al, Stu and Ed shared their lunar voyage with nearly 500 trees.

−	Seeds in Space aim was to make science fun while demonstrating the influence of gravity on germination and growth of plants. Kits were distributed one month before launch to schools in the Netherlands, Germany, Russia, and the Dutch Antilles. Students compared growth of seeds on Earth with those grown onboard the space station, which they observed through a live video downlink from orbit. In space, plants in the dark grew in all directions, while those in the light all grew toward the light. Participants concluded that light or gravity help plants know in which direction to grow, and the absence of both appear to confuse the plants.
−
−	The main goal of this student experiment is to involve as many students as possible in and effort to show that science is fun through a plant growth experiment called Seeds in Space. The educational / scientific objectives of the experiment are: To demonstrate the influence of gravity on the germination and growth of plants to young people (10 to 15 year olds) and others. By engaging in the comparable on-ground experiment, students will experience that science is fun and that the weightless environment of space opens new possibilities. The experiment kit will be distributed one month before launch to schools or other distribution channels.
−
−	The main purpose of this education/ demonstration experiment is to clearly show that plants respond to gravity by a directed growth (experiments on ground) and that they will show a non-preferential or disoriented growth direction when grown in the dark in weightlessness. The in-flight part of the experiment will consist of folding rockets with simple plant growth chambers in which Rucola seeds germinate either with or without light. Crew will setup the growth chamber, initiating seed germination by watering the seeds on the supporting filter paper using a standard 30-ml needleless syringe with luer lock stopcock. Crew will monitor the growth once a day. Since there is no in-flight experience with the proposed plants (species Rucola, rocket lettuce), we require three sets of cultures to be initiated on three consecutive days in flight. The duration for one plant culture is expected to be 3-4 days. Depending on the date and time for the live in flight the call was made.

−	Astronaut Stuart Roosa carried a metal canister about the size of a soda can in his personal kit filled with more than 500 seeds from loblolly pine, redwood, sweet gum, sycamore and Douglas fir trees. He did it in part to honor the U.S. Forest Service, where he had served as a smoke jumper, the first responders to forest fires.
