[Neocp_artsats] Update on Hakuto-R, Blue Ghost, associated hardware

Hi folks,

    All four objects from this launch continue to be tracked.  We nearly 
lost Hakuto-R;  it did a ~50 m/s delta-v at about 20:00 UTC on 2025 Feb 
5.  I've updated the ephems on my site to reflect this.

    The new trajectory would re-enter on Feb 18,  so I assume another 
maneuver is planned.  The lander and rover are planned to land in April, 
  and I assume it'll enter lunar orbit before then.  The company behind 
Hakuto-R,  ispace (sic),  doesn't say anything about what their plans are.

    Blue Ghost hasn't maneuvered much,  but the company behind it says 
they'll do a TLI burn on Feb 8 :

    So the ephems and TLEs on my site are good right now,  but should 
soon become obsolete.  If they fail to make this burn,  they'll re-enter 
at the next perigee (Feb 17 at 14:27 UTC,  over the Atlantic).

    The separator hardware (2025-010C) will re-enter over the 
Argentina-Chile border on 2025 Mar 15 at 12:01 UTC.

    The Falcon 9 upper stage (2025-010D) looks as if it'll be in earth 
orbit for at least a year or so.  As in the past,  proper disposal 
doesn't appear to have been on the agenda.
