# Any news of TESS' lunar flyby; how well did go?

According to this TESS tweet:

TESS is on track for a lunar flyby on 17 May at 06:34:35 UTC (2:34 AM EST). At this point, TESS will be 8,253 km from the lunar surface. In the coming days, follow @NASA, @NASAGoddard, @NASAblueshift and @NASA_TESS for more details.

That's 10 20+ hours ago, and there have been no further tweets.

The last TLE I can see is now two weeks old and certainly invalid considering the lunar flyby would modify the trajectory so much.

Also I don't see or at least recognize TESS in the Minor Planet Center's Distant Artificial Satellites Observation page at all, and JPL's Horizons most recent ephemeris was generated on May 14th, several days before the flyby. I can't find any source where the status of TESS' orbit can be verified.

How did it go? Was it successful? Any info on how close the maneuver was to target?

TESS's lunar flyby allows it to make progress toward it's carefully engineered fairly-long-term (decades) stable high Earth orbit which is in 2:1 orbital resonance with the Moon.
