The Korean Danuri lunar probe and its Falcon 9 second stage rocket are now about 200,000 km from Earth, on their way to the Sun-Earth Lagrange 1 region..

Much love for jcm's phrasing (my bolding):

Is the L1 point an apogee limit for highly elliptical orbits, but only when apogee is in direct line towards the sun?

Great question, one probably more appropriate on a discussion thread devoted to 3 body dynamics. (In this case the bodies are Sun, Earth, and Danuri.)

Here is a comparison of the webcast telemetry from the TESS and KPLO (Danuri) missions.

I picked TESS because when the tiny 362kg telescope launched over 4 years ago, it was the first SpaceX mission to a lunar orbit, in this case a stable 2:1 resonant orbit. The 678kg Danuri is the second SpaceX lunar mission, using a ballistic transfer orbit.

Both missions used an ASDS landing for the booster, and reached similar velocities at SECO2: 10,412m/s by TESS and 10,517m/s by KPLO in the SpaceX inertial reference system. Orbital velocity is about 400m/s more in both cases.

What is different though, is the acceleration profile during the insertion burns, highlighted in the plot below. KPLO peak acceleration was about 6.9g, and TESS about 6.4g. The heavier KPLO only had to throttle down to limit acceleration for the last 10 seconds, whilst TESS throttled down over the last 30 seconds. Also, TESS was the last mission to use a new Block 4 booster.

Just Read the Instructions droneship should return to Port Canaveral tomorrow morning with B1052.

Support ship Bob is now towing, replacing tug Kurt Crosby.

Kurt has sailed directly to the Starlink 4-26 LZ to support Doug and ASOG.

#KPLO

Took me several hours to find all the logos and fonts and add details based on the real fairing logo..

SpaceX workers appear to be removing landing legs from B1052, instead of retracting them. The first leg is already partially dismantled.

The booster arrived at Port Canaveral yesterday.
