64 small satellites from 17 countries were launched on this mission, some with amateur radio payloads. A full list of satellites, can be found at

Four microsatellites including ESEO, carrying an AMSAT-UK FUNcube-4 transponder, were deployed about 2 hours and 13 minutes after launch.

60 CubeSats including Jordan’s JY1SAT carrying a FUNcube-6 transponder and capable of transmitting Slow Scan Digital Video (SSDV) images deployed about 2 hours later.

Surrey Space Centre tweeted:
“A swarm of satellites heads over Guildford including a very large beacon from ESEO!”

Scott Chapman K4KDR tweeted:
“More SSO-A 2-meter IQ replay; JY1Sat 1k2 BPSK decoding perfectly w/ the Dashboard app. Very strong signal on 145.840!”

On Friday, November 16, CEO and Chief Designer of SpaceX, Elon Musk was the guest of honor at the Royal Aeronautical Society in London to present a lecture entitled ‘SpaceX and the future of space exploration’.

The packed lecture was also notable in that the audience saw Elon Musk presented with the Royal Aeronautical’s Society’s highest award – a Gold Medal. This award has been presented since 1909 when the first Gold Medal was given to the Wright Brothers. It is the most prestigious award in global aerospace honoring exceptional contributions and achievements.

Elon Musk founded Space Exploration Technologies (SpaceX), in June 2002. Since then SpaceX has developed the Falcon family of launch vehicles and the Dragon multi-purpose spacecraft.

His personal goal is to eventually enable human exploration and settlement of  Mars.

The amateur radio SwampSat satellite, built by students at the University of Florida (UF), featured in a TV news report.

SwampSat’s primary objective is to demonstrate a compact three-axis attitude control system that permits rapid retargeting and precision pointing (R2P2) capabilities for pico and nano satellites.

Its downlink will use 1200 bps AX25 packet radio on 437.385 MHz with 1 watt of RF.

The team are planning on a December 2012 launch on the SpaceX Falcon 9 into a 450 km orbit with an inclination of 45 degrees.
