Rodent Research Seeks to Benefit Astronauts and Earthlings

Life science took precedence today aboard the International Space Station as the crew explored how microgravity impacts rodent physiology. The space research can help scientists improve astronaut health and treat humans on Earth.

Four Expedition 56 crew members worked together throughout the day examining mice for the Rodent Research-7 study. The experiment observes how microbes affect the gastrointestinal, immune, metabolic, circadian, and sleep systems. Results may help doctors implement programs to keep astronauts healthy on deep space missions. Patients on Earth may also benefit from newer advanced therapies that treat internal disorders.

Commander Drew Feustel joined Flight Engineers Serena Auñón-Chancellor, Ricky Arnold and Alexander Gerst for the rodent study on Tuesday. The orbital lab researchers examined bone structure, collected blood samples and processed and stowed biological samples in science freezers.

Those samples will be returned to Earth inside the SpaceX Dragon cargo craft Aug. 3 for analysis on Earth. Dragon will be packed with station hardware and research gear when it splashes down in the Pacific Ocean. It will be retrieved by SpaceX and NASA personnel for examination by engineers and scientists.

The Russian cosmonauts on the International Space Station are expected to activate amateur radio Slow Scan Television (SSTV) transmissions on 145.800 MHz FM during Monday and Tuesday, July 30-31.

The Inter-MAI-75 SSTV experiment should be active on:
• Monday, July 30 from 16:00-19:30 UT
• Tuesday, July 31 from 13:25-19:15 UT

The SSTV images will be transmitted on 145.800 MHz FM using the Kenwood TM-D710 transceiver located in the Russian ISS Service module. It is expected they will use the PD-120 SSTV format.

Note the ISS transmissions use the 5 kHz deviation FM standard rather than the narrow 2.5 kHz used in Europe. If your transceiver has selectable FM filters try using the wider filter. Handheld transceivers generally have a single wide filter fitted as standard and you should get good results outdoors using just a 1/4 wave whip antenna.

Android Satellite Tracking Applications

AmsatDroidFree ScreenshotIn his blog Peter Goodhall 2M0SQL looks at satellite tracking Apps for Android devices

He says “Satellite tracking applications play an important part in using the transponders available to radio amateurs, of course, experiences of them all vary and are very subjective however we are going to explore what is available on the Android platform.”
