Space Biology, Physics and Suit Checks Start Memorial Weekend
Space Biology, Physics and Suit Checks Start Memorial Weekend
The Expedition 59 crew is starting the Memorial Day weekend studying biology, physics and orbital manufacturing techniques. The space residents will also be busy on the U.S. holiday conducting more research and getting ready for the year’s fourth spacewalk at the International Space Station on Wednesday.
Astronaut David Saint-Jacques of the Canadian Space Agency (CSA) analyzed his own blood sample today testing the new Bio-Analyzer. The biomedical device from the CSA tests a variety of biomarkers to measure molecular signs of health on the station. He also worked on another biology platform that can produce gravity levels up to 2g for research on an array of materials and small organisms.
Japan’s Kibo laboratory module enables astronauts to place and retrieve space exposure experiments outside of the orbiting lab. Flight Engineer Nick Hague swapped some of those exposed samples today from a platform inside Kibo. The long-running materials exposure studies at the station help scientists understand how microgravity and radiation affect a variety of materials.
Christina Koch of NASA continued exploring the production of superior quality optical fibers inside the U.S. Destiny lab module’s Microgravity Science Glovebox. The variety of elements used in the manufacturing process are difficult to control on Earth with gravity bearing down on them. The space-created samples will be analyzed on the ground for their potential to improve a variety of applications such as medicine, navigation, communication and atmospheric monitoring.
At the end of the day, Flight Engineer Anne McClain checked out emergency space navigation techniques using a sextant. She peered at constellations from the cupola during an orbital night period while inspecting and calibrating the hand-held device.
Meanwhile, Commander Oleg Kononenko and Flight Engineer Alexey Ovchinin continued setting up their spacesuits and tools today. Next week they will review procedures and timelines for their approximately six-hour spacewalk for external maintenance scheduled for around 11:45 a.m. EDT Wednesday.

ISS SSTV MAI-75 image 9/12 received by Chertsey Radio Club on Baofeng handheld
A Russian MAI-SSTV event is planned from the International Space Station for Wednesday, June 5 from 12:00-16:00 GMT and June 6 from 11:30-15:30 GMT.
ARISS say they expect transmissions to be at 145.800 MHz FM in SSTV mode PD120. Based on the times received, they do not expect SSTV signals over North America.
Check here for updates https://twitter.com/ARISS_status
This event uses a computer in the ISS Russian Segment, which stores images that are then transmitted to Earth using the ARISS amateur radio station located in the Service Module which employs the Kenwood TM D710E transceiver.
Once the event begins the transmissions should be transmitted on 145.800 MHz FM using the PD-120 SSTV mode.
Amateur radio operators and other radio enthusiasts are invited to post the images they receive at http://www.spaceflightsoftware.com/ARISS_SSTV/index.php
Please note that the event is dependent on other activities, schedules and crew responsibilities on the ISS and is subject to change at any time.
You can use online radios to receive signals from the International Space Station:
• SUWS WebSDR located Farnham near London http://farnham-sdr.com/
• R4UAB WebSDR located European Russia http://websdr.r4uab.ru/

AMSAT-UK payload on ESEO has been activated
AMSAT-UK payload on ESEO has been activated
Frame received by PQ2HX in Brazil at around 14:17 UTC on April 12, 2019
ESA have just released a new mission update for the ESEO Mission. It can be seen at https://www.esa.int/Education/ESEO/ESEO_mission_updates
We are delighted that on April 12, 2019, the BPSK telemetry transmitter, on our payload, was enabled for a period of just over 200 minutes in orbit!
ESEO AMSAT-UK Payload Telemetry Data
Although we were not able to announce this activation in advance, more than ten stations around the world successfully received the telemetry on 145.895 MHz and submitted it to the FUNcube Data Warehouse. We are very grateful to them for their support.
Over 50 channels of Real Time and Whole Orbit Data were collected. For example, a number of on-board temperatures are shown in this graph which covers the period from 11:58 to 13:36 UTC
The very last frame received was captured by PQ2HX in Brazil at around 14:17 UTC.
We are keenly awaiting further possibilities to exercise more of the payload as soon as this becomes possible but, in the meantime, is good to know that all the telemetry channels reported nominal values.
