The astronauts operate fixed frequencies. Ground stations compensate by adjusting both uplink and downlink frequencies for doppler.

Hi Ken...
Just a quick question that came to mind after today's school contact...
Do the astronauts know how to or do they adjust for doppler during the contacts? I know from the ground station that we might be dealing with +/- 8 kHz up there...do they have "steps" built into their radio?
Thanks and keep up the good work!

The East Aurora Union Free School District is currently educating approximately 2040 students in four schools: Parkdale Elementary (K-2), Main Street Elementary (3-5), the Middle School (6-8) and the High School (9-12). We serve a Town of Aurora population of nearly 14,000 residents.
Our students consistently rank within the region's top schools in measures of academic achievement, and the community regularly demonstrates solid support for its schools. Our website address is www.eaur.wnyric.org.
East Aurora Middle School, led by Principal Jeffrey Banks, has a population of approximately 500 students and 37 staff members. The staff of the East Aurora Middle School is committed to excellence in education. We feel that it is vital to show enthusiasm for learning and hope that children want to attend our school. We believe that attendance at school each day is very important and we communicate that attitude to our students.
Students will ask as many of the following questions as time allows:
- Has the Space Station or Astronauts ever been hit by space junk?
- Can you see the Aurora from the Space Station? Are there any
affects on the Space Station? 3. How do you protect yourself from solar storms? 4. If you were to light gasoline in space, would the flames float around? 5. What is the biggest danger working/living on the space station? 6. How come no one lives in the Space Station permanently? 7. What is the largest man-made structure you have seen from space? 8. How would you compare flying in the Navy to your ride on the Space Shuttle? 9. What do you do with your free time? 10. Have you seen a meteor enter the Earth's atmosphere? 11. Who do wish you could bring up onto the Station? 12. Do you have to speak Russian to go to the Space Station? 13. When the Space Station is traveling at 17,000 mph, is there a lot of friction on the Space Station? 14. How long could you survive in space without your space suit? 15. What subjects did you study to be an Astronaut? 16. What inspired you to become an Astronaut? 17. What will your first meal be when you come back to Earth?
Please note, the amateur equipment on the ISS is not functioning in the automatic modes properly and may be silent more than usual. Information about the next scheduled ARISS contact can be found at http://www.rac.ca/ariss/upcoming.htm#NextContact .
Next planned event(s): Juvenile Space Club in Tatsuno, Tatsunomachi, Nagano-pref, Japan, direct via 8J0T, Sat 2007-03-24 00:39 UTC
ARISS is an international educational outreach program partnering the participating space agencies, NASA, Russian Space Agency, ESA, CNES, JAXA, and CSA, with the AMSAT and IARU organizations from participating countries.
ARISS offers an opportunity for students to experience the excitement of Amateur Radio by talking directly with crewmembers on-board the International Space Station. Teachers, parents and communities see, first hand, how Amateur Radio and crewmembers on ISS can energize youngsters' interest in science, technology, and learning. Further information on the ARISS program is available on the website http://www.rac.ca/ariss (graciously hosted by the Radio Amateurs of Canada).
Thank you & 73, Kenneth - N5VHO
