EME & Space Special Interest Project

The EME project group usually meets twice a month to progress this interest, although there are times the event is cancelled at the last minute due to lack of members.   If your interested get on the Paddington 2m repeater to check if its on!

 

Planetary Society Lightsail has gone quiet, they are now relying on a classic IT bug excuse!

27 May 2015

The planetary society launched a prototype lightsail last week, and it appears that a known defect may have got to them! The manufacturer advised that they may have a buffer problem about 2 days before they may have had a buffer problem! Although they continue to try and reset, they are now hoping for that classic IT excuse for crashed PC’s,  Servers, Databases, Networks etc… “Your [xxxxxx] crashed because it was impacted by a stray space particle”. Turns out this really happens, and it happens so frequently to unshielded devices like cubesats that they expect it to occur within 3 weeks!

You can still try and listen out for them on: 437.435 MHz, AX.25, FSK, 9600, call sign KK6HIT.

 

Lots more info available at Lightsail Mission Control

And here is some possible viewing times over Sydney for the next week. Unfortunately the chances of seeing it at the moment are tiny! If the sail does unfold it is expected to be very bright.
