The first set of frequencies belongs to the on-board amateur radio station. Voice contacts are primarily reserved for schools, however, if a crew member has some downtime they’re free to go on-air and make as many contacts as they want. As long as there isn’t any electrical problems the packet modem will also remain on and in ‘store and forward’ mode. Allowing personal messages to be sent to crew members and other hams around the world. The SSTV frequency is rarely used, mostly during special events such as Field Day.

The second set of frequencies are for commercial operations such as EVAs and the docking of resupply ships. On VHF-1 you will hear Cosmonauts communicating with one of several Mission Control Centers around the world. VHF-2 is said to be used by Astronauts though Russian comms have also been logged on this frequency. On 121.750 and 121.125 EVA ‘spacewalk’ activity has been noted with the callsign ‘Soyuz’ being heard on EVA-1. EVA-1 is commonly logged by radio operators in SoCal as its also used by ground crews at LAX. Do note the ISS operates on Moscow Time so you may find the crew more active late at night.

If you’re worried about needing a big set up to monitor the ISS don’t worry, its just like monitoring AO-27, SO-50 or any other FM satellite. All you’ll need is a scanner, general coverage communications receiver or a 2-meter radio with extended receive which pretty much all radios made now a days have. As for an antenna, you will want to use something with gain like the Diamond RH-77/SRH-77 or even a beam antenna like the Arrow Antenna or Elk Antenna. They are fairly low cost and extremely portable.
As we all know Space Shuttle Endeavour is scheduled to do a series of landmark fly-overs around LA and Orange County before landing at LAX later this morning. I already have confirmation 235.400 was being used by the SCA to communicate with the chase planes during the cross country voyage so make sure that is in your radio. As for the ATC freqs its going to be a crap shoot, they will more than likely use Downey (LAX East) for approach into LAX. Possible callsigns being used are Astro 95, Astro 99, NASA 905, Pluto 95 Heavy and Pluto 98.

NASA Hosting First West Coast Launch Tweetup for Earth-Observing Satellite
WASHINGTON — NASA will invite 25 of its U.S. Twitter followers to a Tweetup expected to culminate in the launch of the first of a new generation of Earth-observing satellites from Vandenberg Air Force Base (VAFB) in California.
The event will take place from 9 a.m. to 5 p.m. PDT on Monday, Oct. 24. NASA’s NPP satellite is scheduled to launch aboard a United Launch Alliance Delta II rocket between 2:48 and 2:57 a.m. on Tuesday, Oct. 25.
The National Polar-orbiting Operational Environmental Satellite System Preparatory Project (NPP) will observe many facets of our changing Earth. It will collect critical data on long-term climate change and short-term weather conditions. With NPP, NASA continues many key data records initiated by the agency’s Earth Observing System satellites, monitoring changes in the atmosphere, oceans, vegetation, ice and solid Earth.
During Tweetup activities on Oct. 24, participants will tour Vandenberg’s launch facilities; speak with agency and NPP mission scientists and managers; and interact with each other and NASA’s social media team. For the early-morning rocket launch, participants will watch from a special viewing section that will include a pre-launch concert by “Mobility” from the United States Air Force Band of the Golden West.
Vandenberg is headquarters for the 30th Space Wing, which manages space and missile testing for the Department of Defense and places satellites into polar orbit from the West Coast using expendable boosters.
Registration opens at noon EDT (9 a.m. PDT) on Tuesday, Sept. 13, and closes at 5 p.m. EDT (2 p.m. PDT) on Thursday, Sept. 15. NASA will randomly select 25 participants and create a waiting list. Because this event takes place on an Air Force base with restricted areas, registration is limited to U.S. citizens.
Launch management for the mission is the responsibility of NASA’s Launch Services Program at the Kennedy Space Center in Florida.

(ARRL) Just after 8 AM (EDT) on Tuesday, June 29, the six residents of the International Space Station (ISS) climbed into two Soyuz space capsules as an unidentified object hurtled past them at a speed of 29,000 miles per hour, missing the space station by only 1100 feet.

NANOSAIL-D EJECTS: NASA SEEKS AMATEUR RADIO OPERATORS’ AID TO LISTEN FOR BEACON SIGNAL
HUNTSVILLE, Ala. — Wednesday, Jan. 19 at 11:30 a.m. EST, engineers at Marshall Space Flight Center in Huntsville, Ala., confirmed that the NanoSail-D nanosatellite ejected from Fast Affordable Scientific and Technology Satellite, FASTSAT. The ejection event occurred spontaneously and was identified this morning when engineers at the center analyzed onboard FASTSAT telemetry. The ejection of NanoSail-D also has been confirmed by ground-based satellite tracking assets.
Amateur ham operators are asked to listen for the signal to verify NanoSail-D is operating. This information should be sent to the NanoSail-D dashboard at: http://nanosaild.engr.scu.edu/dashboard.htm. The NanoSail-D beacon signal can be found at 437.270 MHz.
The NanoSail-D science team is hopeful the nanosatellite is healthy and can complete its solar sail mission. After ejection, a timer within NanoSail-D begins a three-day countdown as the satellite orbits the Earth. Once the timer reaches zero, four booms will quickly deploy and the NanoSail-D sail will start to unfold to a 100 square-foot polymer sail. Within five seconds the sail fully unfurls.
“This is great news for our team. Weâ€™re anxious to hear the beacon which tells us that NanoSail-D is healthy and operating as planned,” said Dean Alhorn, NanoSail-D principal investigator and aerospace engineer at the Marshall Center. “The science team is hopeful to see that NanoSail-D is operational and will be able to unfurl its solar sail.”
On Dec. 6,, 2010, NASA triggered the planned ejection of NanoSail-D from FASTSAT. At that time, the team confirmed that the door successfully opened and data indicated a successful ejection. Upon further analysis, no evidence of NanoSail-D was identified in low-Earth orbit, leading the team to believe NanoSail-D remained inside FASTSAT.
The FASTSAT mission has continued to operate as planned with the five other scientific experiments operating nominally.
“We knew that the door opened and it was possible that NanoSail-D could eject on its own,” said Mark Boudreaux, FASTSAT project manager at the Marshall Center. “What a pleasant surprise this morning when
our flight operations team confirmed that NanoSail-D is now a free flyer.”
If the deployment is successful, NanoSail-D will stay in low-Earth orbit between 70 and 120 days, depending on atmospheric conditions. NanoSail-D is designed to demonstrate deployment of a compact solar sail boom system that could lead to further development of this alternative solar sail propulsion technology and FASTSATâ€™s ability to eject a nano-satellite from a micro-satellite — while avoiding re-contact with the FASTSAT satellite bus.
