Youngsters in Europe, US Get Front-Row Seats to Space via Ham Radio:

Youngsters in Europe, US Get Front-Row Seats to Space via Ham Radio:

Now part of the ISS Expedition 15 crew, US astronaut Suni Williams, KD5PLB, has continued her run of successful Amateur Radio on the International Space Station (ARISS) school contacts. In late April, she enlightened youngsters in Italy, Germany, Virginia and Illinois about what it's like to live aboard the ISS. Williams has been in space since December and is scheduled to return home next month via the space shuttle that will bring her replacement. During the first of two ham radio conversations on April 23 with students at the Scuola Europea Varese in Varese, Italy, Williams allowed that she's growing tired of space meals.

"They were tasty for the first couple of months, but now it's getting a little bit old, because the menu sort of repeats," Williams responded. "It's about a 10-day cycle, and then you start eating the same things over and over again, so I try to be creative and mix new things with each other."

Shane Lynd, VK4KHZ, served as the Earth station for the event. Students at the school spent about three months learning about the ISS. An audience of about 300 looked on during the contact, which attracted media coverage from newspapers and television. Verizon Conferencing provided a teleconferencing link between Australia and Italy.

A few hours later, youngsters at Kingston Elementary School in Virginia Beach, Virginia, spoke with Williams during a direct VHF contact between NA1SS and control op Ed Williams, KN4KL. Thirteen Kingston third through fifth graders participated, while the rest of the school's nearly 600 students watched via closed-circuit TV. Julia, whose father had graduated from the US Naval Academy with Suni Williams, wanted to know how long it took to prepare for a space walk.

"Well, it takes a little while," Williams explained. "It's sort of like when you're going diving. We're going to breathe 100 percent oxygen, and so we have to make sure that we get all the nitrogen out of our system. So that's the longest preparation time, and then we have to get the spacesuits ready." She said it typically takes four to five hours before the astronauts are ready to open the hatch and go out into space.

Members of the Virginia Beach Amateur Radio Club (VBARC) provided the ground station and support for the ARISS event, which was the subject of a newspaper article in the Virginian Pilot. (The ARRL Virginia Section Web site has a copy of the article and additional information.)

Two days later, about a dozen youngsters attending Christian Life Elementary School in Rockford, Illinois, had their "day in space." Youngsters there chatted with Williams at the helm of NA1SS via Earth station control operator Shari Harlan, N9SH. Williams told one questioner that she believes the next step for the human spaceflight program is to return to the moon.

"We've got a lot that we can learn from living in a different type of gravity environment if we want to explore further, potentially go out to Mars or some other part of the universe," she said. "If we're only at the moon, we'll have only a small delay in communication -- maybe a two-second delay -- and we need to learn how to work autonomously without always [having] the help of the ground. It would be nice to have a moon base to see how that would work and see if we can still survive there."

Upward of 1000 students looked on during the ARISS QSO, and audio and video were fed live to a local Amateur TV repeater.

On April 28, Williams fielded more questions from students at the Samuel von Pufendorf Gymnasium, a middle and high school of some 675 students in Floeha, Germany. The direct contact was between NA1SS and the school's Amateur Radio club station DL0GYM, with Harald Schoenwitz, DL2HSC, as the control operator. All of the students who took part in the event had obtained their Amateur Radio licenses in advance of the contact.

Williams told the students she wished the ISS had Internet access. "It really would be helpful," she remarked. She noted the crew does have access to e-mail, however. She also said that the crew can see the northern lights from above, and on one occasion, an aurora occurred during a space walk. "It was a little creepy to see the green lights flashing," she said.

About 50 people plus news media looked on as the approximately 10-minute contact progressed flawlessly. Five newspapers, three radio stations and the regional TV channel reported on the event. The von Pufendorf contact was the 290th since the ARISS program began coordinating ham radio events for schools when the first space station crew came aboard in November 2000.

ARISS is an international educational outreach with US participation by ARRL, AMSAT and NASA.
