Observed Athena of Intuitive Machines on its way to the Moon. Got Doppler data on two days, and it matches nice on a fitted TLE, which was found at the SatNOGS forum. Thanks Scott Tilley 🇺🇦 🇨🇦 for the hints to the GS.

We have confirmation #BlueGhost stuck the landing! Firefly just became the first commercial company in history to achieve a fully successful Moon landing. This small step on the Moon represents a giant leap in commercial exploration. Congratulations to the entire Firefly team,

Observed Athena #IM2 of Intuitive Machines again today. It was also groundlocked to India. Ignored the trajectory correction of march 1 and fitted the orbit.

Received a nice Doppler curve of Athena #IM2 of Intuitive Machines. I matched a Astropy/Poliastro model to it, showing an altitude of 105km. The complete orbit is visible and it is currently not hiding behind the moon. It appears to be flying circles around the moon seen from Earth.

Last night, several satellites of the Transporter 14 launch were optically observed. For more information see the SatNOGS forum: community.libre.space/t/transporter-…
