Due to the significant damage to the RFAâ€Ös One launcher stage during the
static firing test at SaxaVordâ€Ös spaceport in the Shetland Islands,
Scotland (UK) on August 19th, AMSAT-EAâ€Ös UNNE-1 and MARIA-G satellites
launch will be delayed.
They were originally planned for launch on September 30th, and now it is
not expected before 2025. Video of the BBCâ€Ös coverage of the incident is
available here:

UNNE-1 and MARIA-G are both based on the currently orbiting HADES-D
(SO-121) hardware, providing a repeater service for voice and data
communications in FM and FSK-derived modes. They have been designed and
built by AMSAT-EA together with private sector companies and with the
collaboration of Universities and educational centres.
Both satellites will offer licensed radio amateurs around the world the
opportunity to make FM and FSK QSOs, including FT modes, such as FT-4 and
FT-8, or AX.25/APRS. The satellites will also transmit telemetry with their
status, voice messages and CW.
UNNE-1 includes an Arduino-based board with software from Nebrija
University of Madrid. The students have developed a small decoding game
with a space story as a background. The satellite sends a clue each week in
its FSK telemetry so that radio amateurs can solve the challenge. This game
will be detailed on the AMSAT EA website and on the Nebrija University one.
MARIA-G also includes two CW reception games/challenges implemented by
students from the MarÃa Guerrero high school in Collado Villalba, also from
the region of Madrid.
One of the games consists of receiving the coordinates of a significant
place on Earth (for example a city, a monument…) and the other about
receiving a code that will correspond to a question about Science. Both
games will have a dedicated web page.
MARIA-G also includes a small experiment, developed by the
Fraunhofer-Gesellschaft research center in Germany. It consists of a proof
of concept for the transmission of a TS-UNB waveform from a low Earth
orbit. Therefore, it will transmit a TS-UNB message according to the
ETSI-TS-103-357 standard. It is intended solely as a research and
development project with no commercial intention.
The ITU modulation classification would be 100K W2DWW but the bandwidth
will be reduced. The operation of this experiment will be carried out by
AMSAT-EA.
The UNNE-1 and MARIA-G satellites are part of the Erminaz mission, a joint
effort of AMSAT-DL, AMSAT-EA and LibreSpace Foundation, each organization
flying its own satellites and using LibreSpaceâ€Ös PicoBus deployer.
The mission management with the German Space Agency (DLR) and the launcher
(RFA), as well as with the UK authorities, has been carried out jointly,
with AMSAT DL leading it.
