HamTV Returns to International Space Station

/

SpaceX CRS-30 recently returned the HamTV system back to the International Space Station after the system was sent back to earth for repairs in 2019. The Digital Amateur Television (DATV) equipment powering HamTV is typically used in conjunction with school contacts to send video and audio of the contact events to viewers on earth.

HamTV was originally operational in 2013 but failed 6 years later in 2019. With the equipment back on board the ISS, AMSAT expects the equipment to be operating in the coming weeks.

The British Amateur Television Club (BATV) has extensive documentation related to HamTV, including how to receive the DVB-S protocol transmitting from the ISS - https://batc.org.uk/

Amateur Radio Stands Ready to Support Eclipse Operations

The upcoming 8th April 2024, solar eclipse has many excited about the opportunity to witness the darkness of totality. Spectators from across the country are travelling to the path of total darkness that will stretch from South Texas to Northeastern Maine.

Some states are anticipating more than a million travellers for the event. In the impacted areas, schools will be letting students out early for the day, and residents are being encouraged to avoid driving on the day of the event. Emergency response organizations are adding staff for the event in many areas. The eclipse is expected to directly impact parts of 14 states as it moves across the country. The travel impact alone could be substantial.

In preparation for the event, many state emergency management organizations have called on local hams to provide communication services via HF nets and locally on VHF/UHF frequencies. There have been numerous planning meetings, exercises, and preparations across the country. The ARRL Emergency Management department has worked with ARRL Section Emergency Coordinators and Section Managers in the directly affected areas to collect the frequencies each Section plans to utilise and to assist in any frequency conflicts. Hams across multiple states and ARRL Sections have been practising their communications capabilities via Winlink, SSB, and CW.

Discarded "Space Junk" From Iss Falls To Earth Without Incident

/

Tossed from the International Space Station in 2021, nine batteries weighing a total of 2.6 metric tonnes re-entered Earth's atmosphere on Friday, the 8th of March, in free-fall, crashing into the Atlantic Ocean between Guatemala and Florida.

In the days and weeks prior, the impending arrival of the so-called "space junk" set off alarms in various parts of Europe, including Germany and Luxembourg, with predictions being made of the damage the debris might do if any of it arrived in populated areas there.

The European Space Agency's Space Debris and Independent Safety Offices provided updates to its member states throughout the day. In Bonn, Germany, the Federal Office for Civil Protection and Disaster Relief, National Warning Center alerted the public to the possibility of hearing a sonic boom or seeing luminous phenomena overhead.

At the time of the battery pack's release, it was considered the largest object to be tossed from the ISS.
