Soyuz Mission Misses the Space Station

Soyuz mission launched about 27 minutes ago has had an anomaly and will not make it to the ISS. Heading back to Earth for a ballistic landing currently. Search and rescue personnel will take about 1.5h to reach the expected landing point. Godspeed guys. https://spaceflightnow.com/2018/10/10/live-cov...

Re: Show us your rocket room / shed / workshop

Nice Cato! You will love the fact you can take much bigger cuts and get better surface finishes because of the bigger and stiffer bed.

Have you considered a DRO? Best idea since sliced bread :wink:

Tripoli (Victoria) Launch, 6/7th October 2018

Tripoli (Victoria) Launch, 6/7th October 2018

Unfortunately due to restrictions on access to the farm currently (the crops are up) the launch scheduled for October 6/7 2018 has been cancelled.

Unfortunately there will be no more launches at Serpentine in 2018.

Preping for Second Flight

Preping for Second Flight Not My Biggest Fan So, servos were replaced after failing on the earlier flight due to the SBEC going short circuit.
