Testing the hardware on the observatory’s telescope element and spacecraft element demonstrate that these systems individually meet their requirements. However, recent findings from the project’s Standing Review Board (SRB) indicate more time is needed to test and integrate these components together and then perform environmental testing at Northrop Grumman Aerospace Systems in Redondo Beach, California, the project’s observatory contractor.
Looks like they are being very careful. Considering that if it fails there is no rescue, I can see why. So now we get to wait yet another year. Darn.
