Looks like ZY-3 #2 might be going up pretty soon..... (source)
This launch will now only take place in 2016.
Aleph is a constellation os Argentinian Earth observation satellites. The first mission will be lauched by a CZ-4B on April 30, 2016.
Does anyone has any specific information regarding the Ziyuan-3 (2) satellite? Is this satellite very similar to the firsf ZY-3? Thank you!
