it was a great time but no longer maintainable by c.Kleinhuis contact him for any data retrieval,
thanks and see you perhaps in 10 years again

Solar sail test fail



http://www.fractalforums.com/index.php?action=gallery;sa=view;id=19705

Fragementarium-v1.0.27 , Kali's Asurf, DE-Kn8 ..

Made me think of a failed testing of the microsats planned to be boosted on intergalactic travel by high intensity laser pulses.
