Space Station Contact With Students In Malta

An ARISS contact between students at Stella Maris College, Gzira, Malta, callsign 9H1MRL and the International Space Station (ISS) took place successfully at 12:34 GMT on Wednesday, February 15. It was the first ever ARISS contact from the European island nation of Malta.

The ISS crew member, astronaut Josh Cassada, KI5CRH, used the ISS callsign OR4ISS on the downlink frequency of 145.800 MHz. The ARISS team Malta made use of the callsign 9H1MRL, the club call of the Malta Amateur Radio League (MARL).

The signal was receivable in the British Isles and across Europe. The contact was conducted by five local radio amateurs; Dominic Azzopardi, 9H1M, Manuel Grech, 9H1GW, Andrew Vella, 9H2AV, Trevor Sammut, 9H5TS and Anthony Scicluna, 9H2AS. The station was set up in the school’s auditorium with a 10 element crossed Yagi and rotator on the roof.

Stella Maris College is part of a network (La Salle Malta) of Lasallian Colleges that include De La Salle College and the Mellieha Retreat Centre. The schools take their inspiration from their founder, John Baptist de la Salle. In the Christian faith, John De La Salle is venerated as the Patron Saint of Teachers. La Salle Malta was founded as a single school in 1903 by the Brothers of the Christian Schools and is now the La Salle Malta’s Lasallian Colleges, run by the Malta Trust of the Brothers of the Christian Schools.

Stella Maris College hosted this ARISS contact for participating students in grades 5 through 10 (ages 9-15 years). Stella Maris College has partnered with members of the Malta Amateur Radio League (MARL) (9H1MRL) who provided support during the ARISS contact. Members of MARL have also made presentations to students about amateur radio, and demonstrated satellite tracking and talking to other hams through amateur radio satellites.

As a member of MARL, Stella Maris College has previously operated their own amateur radio station. Members of other organizations that are also part of educational activities surrounding this ARISS contact include; the University of Malta, the Malta College for Science and Technology, Malta Council for Science and Technology and Malta College for Arts, Science and Technology.

Basically, a Lasallian School has the following characteristics:
A) respect for each student as a unique person.
B) A strong spirit of Community.
C) A school of Quality.
D) A school that embraces everyone.
E) Shows special preference for persons who are considered poor financially, morally, physically, psychologically.

Mission statement:
Our school is a place where everyone strives to create and nurture a holistic, inclusive and well-ordered learning climate thereby ensuring a high-quality, values-based academic preparation.

The school has an astronomical observatory and electronics forms part of the school curriculum.

The whole event was streamed live, and archived on YouTube at the following URL:

AMSAT Engineering Recruiting Volunteers

+ RF Engineer
AMSAT is looking for an EE with RF experience to join its FOX-PLUS team.  You'll collaborate with an all-volunteer team of up to ten electrical, mechanical, software and systems engineers.  You will have the opportunity to design and build the RF communications subsystems for a series of low earth orbit, 1U-3U CubeSats to support AMSAT's educational and engineering objectives.

You should have a working knowledge of analog and digital communications protocols (e.g., FM, PSK, FSK) to provide digitally synthesized audio for FM modulated VHF/UHF/SHF voice and telemetry channels. Development opportunities can begin with modification of previous FOX designs and/or by starting with a blank sheet for an original design.

+ Mechanical Engineers
AMSAT is looking for Mechanical Engineers to join its FOX and GOLF CubeSat teams.  You'll collaborate with an all-volunteer team of up to 12 electrical, mechanical, software and systems engineers.  You will have the opportunity to use your structural design and analysis skills in the development of a series of low earth orbit and highly elliptical orbit, 1U-3U  CubeSats to support AMSAT's educational and engineering objectives.

Your contribution may include a) the development of the spaceframe and deployable solar panel subsystem, b) the analysis of the thermal characteristics of the CubeSat  and the design of the thermal management system, c) preparation and oversight of the environmental testing procedure, and/or d) management of documentation of the CubeSats adherence to the launch provider's and space vehicle owner's specifications.

Our volunteers typically spend five hours per week on their project and attend a weekly online update meeting. An Amateur Radio license and CubeSat experience is helpful but not necessary.  U.S. citizenship or proof of permanent residency is required.

Interested persons should send an email with their resume/curriculum vitae to:

Australian Hams Plan Commemorative Event

A group of amateurs, including Dan Sutton, VK6NAD, Michael Tutt, VK6TU, and others, will activate the special event call sign of VI6CRO (to be confirmed) in recognition of the NASA Carnarvon and Overseas Telecommunications Commission (OTC) Carnarvon historic location.

The activation will occur from April 17 ending April 23 to coincide with the massive surge of visitors as a result of the April 20 Eclipse event in the area. The Station will be set up in the middle of the historic OTC buildings between the Casgrain Horn used during Apollo 11 and the large 30m Dish.

The station will have FM satellite capability and intends to organize contacts with Australian and Indonesian amateurs, hopefully via the ISS repeater and AO91 if they are operating at that time.

Also near the station site is the Carnarvon Space and Technology Museum. Buzz Aldrin opened the museum in June, 2012, so the NASA connection will resonate through the event at which many hundreds of visitors are expected to attend daily.

Crew-6 Launch Slips

NASA has delayed the launch of a commercial crew mission to the International Space Station by a day to give SpaceX additional time to complete work on the vehicle. The crew will include three licensed amateur radio operators for a six-month stay on the ISS.

At a briefing after a flight readiness review for the Crew-6 mission Feb. 21, NASA announced it has rescheduled the launch of the Crew Dragon spacecraft to Feb. 27 at 1:45 a.m. Eastern. The Falcon 9 launch of the spacecraft had been planned for Feb. 26.

The Crew-6 launch will carry two NASA astronauts, Mission Commander Stephen Bowen, KI5BKB, and Pilot Warren "Woody" Hoburg, KB3HTZ, along with UAE (United Arab Emirates) astronaut Sultan Al Neyadi, KI5VTV, and Roscosmos cosmonaut Andrey Fedyaev, who will serve as mission specialists to the space station for a science expedition mission.

If the launch slips again, there is another launch opportunity Feb. 28 at 1:22 a.m. Eastern, followed by three opportunities March 2 through 4.
