Send your call sign to Mars

NASA are collecting names to be put on a microchip that'll be onboard the Mars Science Laboratory rover heading to Mars in the fall of 2011.

Some Radio Amateurs have been adding their call sign to last name field.

As well as having your call sign travelling around the Martian surface you also get a electronic commemorative certificate to print out.

The rover has an unusual connection with radio - it has special Morse Code indentations on its wheels that will spell out the initials JPL in Morse as it travels around Mars.
JPL stands for Jet Propulsion Laboratory, builders of the rover.

ARISSat-1 Activation 04/12


The transmissions will begin on Monday 11 April 2011 at 14:30 UTC and continue
until 10:30 UTC on 13 April 2011.

Due to the fact that the solar panels are covered, the satellite will be
powered only by the onboard battery. The satellite will run in low power mode.
This means that the transmissions will cycle ON/OFF. They will be ON for 40-60
seconds and OFF for 2 minutes.

145.950 MHz FM Downlink:
FM transmissions will cycle between a voice ID, select telemetry values, 24
international greeting messages in 15 languages and SSTV images. One of the
messages will be a conversation between Yuri Gagarin and ground control.

145.919 MHz CW Beacon
The CW transmissions will be callsign ID, select telemetry, and callsigns of
people actively involved with the ARISS program.

145.920 MHz SSB BPSK-1000 Telemetry
The BPSK transmissions will feature a new 1kBPSK protocol developed by Phil
Karn, KA9Q to be readable in low signal level conditions. The BPSK data will
transmit satellite telemetry. Free ground station soundcard demodulator and
display software will be available.

Note that the linear transponder will not be active during this event.
