HST has no docking adapter and no navaids. And as Hubble Hugger pointed out, Progress' terminal approach rate is too fast for a delicate target like HST. -- JRF Reply-to address spam-proofed - to reply by E-mail, check "Organization" (I am not assimilated) and think one step ahead of IBM. |

Or inclination, at least until the pad in Kourou is operational. -- JRF Reply-to address spam-proofed - to reply by E-mail, check "Organization" (I am not assimilated) and think one step ahead of IBM. |
