The ARISS Operations UK Team have released a 57 minute video of the ARISS event at Mary Hare School for the deaf in Newbury, on Tuesday, October 12, 2021.

Radio amateurs in the UK and across Europe were able to receive the signal from the ISS on 145.800 MHz FM.

The Amateur Radio contact between students at the school, call sign GB4MHN, and astronaut Mark Vande Hei KG5GNP using the call sign NA1SS from onboard the International Space Station, takes place at about 46 mins into the video.

AMSAT-EA developing URESAT-1 satellite

AMSAT-EA LogoAMSAT-EA is already working on the mission of what will be the first satellite of URE (Spain’s national amateur radio society), URESAT-1.

A translation of post by URE says:

At the IberRadio Fair, held in September, the possible functionalities that this satellite could implement were shown.

Details of the evolutions planned for the URESAT satellite are based on the experience of the previous GENESIS missions, with the GENESIS-N and GENESIS-L satellites, launched into space with Firefly on September 3 (although, they failed to reach orbit due to failure of the thruster), and EASAT-2 and Hades, which will launch with SpaceX on January 10 from Cape Canaveral.

Although the final functionalities must be approved by the URE itself, it is expected that said satellite will incorporate an FM voice repeater, FSK transmissions and some type of on-board experiment, which could be a camera with SSDV transmissions or some type of propellant.

If the necessary financing is obtained, it is expected that this satellite could be sent into space by the end of 2022.

ARISS contact scheduled for students in Newbury UK

Amateur Radio on the International Space Station (ARISS) has received schedule confirmation for an ARISS radio contact with astronauts. ARISS is the group that puts together special amateur radio contacts between students around the globe and crew members with ham radio licenses on the International Space Station (ISS).

This will be a direct contact via amateur radio between astronaut Mark Vande Hei KG5GNP onboard the International Space Station and students at the Mary Hare School, Newbury, UK.

Amateur radio station GB4MHN will be the ham radio ground station for this contact.

The downlink frequency for this contact is 145.800 MHz FM and may be heard by listeners in Europe that are within the ISS-footprint.

The ARISS radio contact is scheduled for Tuesday, October 12, 2021 at 11:12:33 UTC, which is 12:12:33 BST or 13:12:33 CEST.

A live feed from the school will be available here

School Information:

Mary Hare is an aural school for the deaf, we don’t use sign language, instead we teach students to develop lip reading skills and make use of technology. The contact is important for the school as not only will it help inspire students to STEM, it will hopefully demonstrate that no matter the difficulties they have with communication; there are still ways they can accomplish amazing things (“the sky is not the limit!”).

During the week the students will see some exciting chemistry demonstrations, design and fly model rockets, see some space suits, and do some astronomy (observing Jupiter and Saturn in the evening). In lessons they have researched and discussed what it might be like to live in space, done some space themed art, and looked at astronaut food. Hopefully it will be an exciting and inspiring week.

Students First Names & Questions:

1. Rosie (13 yrs): Do you have to learn a sign language to communicate if something goes wrong with the radios in your suit?

2. Jacob (18 yrs): How do you tell directions in space?

3. Harrison (11 yrs): What do the northern lights look like from space?

4. Hollie (16 yrs): How can you shower in zero gravity?

5. Jasper (13 yrs): What’s your most favourite space technology?

6. Milly (18 yrs): If there was a fire, how would you evacuate?

7. Dominika (14 yrs): Do mobile devices work in space? For example, a Smart Phone?

8. Oliver (13 yrs): If you could take one thing from home into space, to make life more fun what would you take and why?

9. Zak (17 yrs): What is it like to wake up and see the earth from space

10. Julia (15 yrs): How long have you been in space for?

The UoSAT-1 story: ingenuity, teamwork and lots of favours!

UoSAT-1 OSCAR 9 Team

UoSAT-1 – OSCAR 9 and Team

UoSAT-OSCAR-9 (UoSAT-1), developed at the University of Surrey by Martin Sweeting G3YJO and his team, was launched into orbit 40 years ago on October 6, 1981.

UoSAT-1 was the first modern microsatellite with in-orbit re-programmable computers and its signals were decoded and analysed by thousands of radio amateurs, schools & universities around the world.

Find out about the audacious favours Sir Martin Sweeting G3YJO called in to get UoSAT-1 off the ground in 1981, and the ingenious hack he used to vibration test it using a car and Guildford High Street!
