They may bring books, music, and musical instruments with them. Some astronauts enjoy hobbies, such as drawing, photography, and HAM radio. During missions, astronauts are very busy.
Understanding SWR by Example - American Radio Relay …
www.arrl.orgexample. In the typical ham station setup, a transmitter is connected to a feed line, which is then connected to the antenna. When you key the transmitter, it develops a radio fre-quency (RF) voltage on the transmission line input. The voltage travels down the feed line to the antenna at the other end and is called the forward wave.

International Space Station Status
www.nasa.govBoth Crew-2 and Crew-3 harvested the space station’s first crops of chile peppers for thePlant Habitat-04 experiment. This plant experiment was the longest in the history of the space station at 137 days. Studies like this one could help enable viable and sustainable crop production for future missions as humans explore the Moon and Mars.
