The crew of the space shuttle Endeavour, which is scheduled to begin an 11-day mission Aug. 7, will conduct a variety of educational activities, with a key role played by teacher-turned-astronaut , announced yesterday.

The activities targeted to K-12 students are add-ons to the shuttle crew鈥檚 primary missions, which include attaching a huge truss segment to the orbiting . Ms. Morgan, a former elementary school science teacher from Boise, Idaho, will operate the shuttle鈥檚 mechanical arm to transfer equipment from the shuttle to the space station, NASA officials said at a July 10 press briefing.

Though the officials portrayed Ms. Morgan as just one member of the crew, they were also aware that her past role as a teacher is sure to capture the public鈥檚 attention.

Ms. Morgan, as many educators remember, was the teacher selected in 1985 as the backup to teacher-in-space , the social studies teacher who died when the space shuttle Challenger exploded during its ascent on Jan. 28, 1986.

Ms. Morgan, now 55, subsequently went through the full astronaut-training program and qualified as a mission specialist.

How to Thrive Up There?

Various media organizations have been interviewing teacher and astronaut Barbara R. Morgan ahead of her upcoming passage on the space shuttle Endeavour STS-118 mission to the International Space Station.

On the upcoming mission, which NASA calls , Ms. Morgan will help conduct three planned live 鈥渄ownlink鈥� sessions, in which students will ask questions that they have prepared in advance, NASA officials said at the one-hour press briefing on the educational aspects of the mission. The briefing was held at NASA鈥檚 , in Houston, but reporters were also able to participate from a conference room at NASA鈥檚 headquarters in Washington.

69传媒 will take part in the 20-minute downlink sessions from one of three sites: the , in Boise; the , in Alexandria, Va.; and the , in Lynn, Mass. The sessions will be broadcast live on NASA Television.

The first downlink session, at the Boise center, will take place on the seventh day of the mission, or Aug. 13, if the shuttle launch takes place as planned on Aug. 7. The other two sessions are part of an extended schedule and will take place only if the mission is extended to 14 days, officials of the space agency said.

Joyce Winterton, NASA鈥檚 assistant administrator for education, said the mission鈥檚 educational goals include improving NASA鈥檚 future capacity to conduct space missions and helping attract and retain students in the science, technology, engineering, and math, or STEM, disciplines.

Ms. Winterton said that Ms. Morgan, who was deeply involved in planning the educational activities for the mission, helped frame them within three 鈥渂ig questions鈥�: How will people live and work in space? How will they stay healthy and physically fit in space? How will they grow food in space?

Seeding Interest in Space

To address the third question, on the challenge of growing food in space, the shuttle crew members will transfer to the space station two small, collapsible growth chambers for plants, one containing basil seeds, the other containing lettuce seeds.

The transparent tops of the chambers are accordion-shaped and will expand as the plants grow. A space-station crew member will tend the plant experiment, and take video and still images of the progress of growth.

That activity is also connected to a school-based 鈥渆ngineering design challenge鈥� that will be open to any teachers and students beginning this fall. It consists of having students design and build plant growth chambers that could withstand conditions on the surface of the moon. Teachers will be able to download free instructions for the activity.

Teachers will be able to request packets of basil seeds that were flown on STS-118, which NASA will distribute this fall along with basil seeds that were not flown, for comparison. 69传媒 will grow the seeds in their growth chambers.

The engineering design challenge was created with the help of the . The project is based on the group鈥檚 national standards for technology education, according to Shelli Meade, the research-projects director of the ITEA, which is based in Reston, Va.

The association has helped organize several professional-development sessions for teachers about the challenge prior to the mission.

Setting an Example

Another postmission unit that NASA is offering schools involves health and fitness lessons in which students can do exercises modeled after the real-life physical training of humans traveling in space. The NASA Fit Explorer project calls for students to track their progress, learn the science behind nutritional and physical fitness, and relate physical Earth-based needs to the requirements of exploring in space.

Additional educational aspects during the mission include the use of the space station鈥檚 , which is accessible via the World Wide Web, and communications between mission participants and amateur-radio users on Earth.

Some education-related activities have taken place in advance of the mission, such as a pennant-design challenge for students. The winning pennant, by a student from Mount Laurel, N.J., is to be unfurled in space.

Similar activities have been conducted during previous shuttle missions. But NASA officials said Ms. Morgan, in her role as a crew member, will be perhaps the most powerful lesson for students on the flight.

She shows 鈥渨hat it takes to be a scientist, mathematician, and engineer,鈥� said Ms. Winterton. And, she said, Ms. Morgan鈥檚 planned operation of the robotic arm 鈥渋s an opportunity for young students to see that high-tech has practical application.鈥�
