Michael R.Owen, W9IP:

I am in the final phases of adding Space-Track automated logon/download capability to Nova for Windows. A ready-for-primetime version of Nova will be available in a few days. When finished, downloading of Keplerian elements will be as smooth and transparent for Space-Track.org as it is currently for Celestrak.com.
The new version of Nova will be announced here and on NLSA's web site http://www.nlsa.com

News from Dr. T.S. Kelso, TS.Kelso@celestrak.com:

(2005 January 11): According to the notice posted on the NASA/GSFC OIG web site yesterday (below), they will cease operation on 2005 March 31. CelesTrak will continue to disseminate TLEs until that date, but will be unable to do so starting April 1 (under the terms of US Public Law 108-136). If you have not done so already, I encourage you to obtain a Space Track account (http://www.space-track.org) as soon as possible in preparation for this transition. - TS
