International Space Station Commander Anton Shkaplerov will lead fellow Expedition 54-55 crewmates Scott Tingle and Norishige Kanai back to Earth early Sunday morning. The trio will undock from the Rassvet module inside the Soyuz MS-07 spacecraft on Sunday at 5:16 a.m. Just three and a half hours later the homebound crew will parachute to a landing in Kazakhstan after 168 days in space. NASA TV will broadcast live the undocking and landing activities.
Three more crew members are waiting in Kazakhstan to replace the Expedition 54-55 crew. Soyuz MS-09 Commander Sergey Prokopyev will launch with Expedition 56-57 Flight Engineers Serena Auñón-Chancellor and Alexander Gerst on June 6 from Kazakhstan on a two-day ride to their new home in space.
The following week after the crew swap activities, NASA astronauts Ricky Arnold and Drew Feustel will go out on their third spacewalk together this year. The duo will install new high definition cameras and route cables on the Harmony module during the 6.5-hour spacewalk planned for June 14. Tingle is readying some of the gear today that will be installed during that spacewalk.
Finally, Feustel and Arnold spent a little over half their day today setting up the new Cold Atom Lab (CAL). The duo installed the scientific gear in the Destiny lab module, connected cables and inspected fiber optics before powering up the low temperature research device. The CAL will chill atoms to temperatures barely above absolute zero allowing scientists to observe quantum behaviors not possible on Earth.

In episode 21 of the TX Factor show Bob McCreadie G0FGX and Mike Marsh G1IAR discuss the linear (SSB/CW) amateur radio satellites and give a demonstration with the CAMSAT XW-2F satellite.
They also review the new Icom IC-7610 transceiver, and look at programming your SDR handie and running a SharkRF openSPOT digital radio IP gateway.
As always, in their free-to-enter draw, there’s a chance to win two great amateur radio-related items – a Prism dust cover for your rig, and a copy of the book “Amsats and HamSats”.
Bob and Mike discuss satellites near the start of the show and towards the end at 48:08 they give a live demonstration of the CAMSAT XW-2F SSB transponder satellite.

Bulgaria’s first CubeSat, EnduroSat One, was launched to the International Space Station on the cargo resupply OA-9 mission on May 21, 2018 from the Mid-Atlantic Regional Spaceport in Virginia, USA. On May 24 the Cygnus capsule docked to the Station and the satellite was taken onboard the ISS.
The satellite will be deployed from the ISS in the coming weeks.
The mission aims to popularize the Radio Amateur activities in Bulgaria and it will include cooperation with Bulgarian Federation of Radio Amateurs (BFRA), including workshops and additional educational activities.
The spacecraft has been completely build in Bulgaria. This first educational mission aims to inspire young Bulgarians and give them the chance to participate in a real space program!
The Space Challenges and EnduroSat teams have invested considerable resources, time and effort in preparing the Bulgarian CubeSat. In order to support the Radio Amateur community, the satellite emits in frequencies which are readily available for receiving by anyone with basic communication skills and radio equipment.
It is hoped the mission will help more young Bulgarians learn the basics of satellite communications through practical exercises empowered by the orbiting satellite.
Radio amateurs from around the Globe will be able to listen to the satellite beacon and to receive telemetry data from the satellite on a regular basis. They will be able to connect to the satellite, receive detailed telemetry information and receive a confirmation from the satellite for every established connection which will serve as QSL card.
Beacon: 437.050 MHz CW and 9600 bps GMSK AX.25
