Further to my last here's an initial estimate of the relay orbit of Tianwen-1 based on published data and a guess at the periapsis time of the burn to change the orbit which will not be correct. Later today I'll fit it to Doppler and correct it. https://twitter.com/coastal8049/status/1394350456982237184 Epoch = 17 May 2021 00:00:00 UTC CoordinateSystem = MarsInertial DisplayStateType = Keplerian SMA = 9492.6666120816 ECC = 0.6162045788699853 INC = 86.9 RAAN = 112.2333081866489 AOP = 168.9402158894392 TA = 0.0 Regards, Scott Tilley On 2021-05-17 7:58 a.m., Leo Enright via Seesat-l wrote: > Is there some way I can display Tianwen-1's orbit on Celestia or > similar?
