"Pseudo-MPEC" for 2019-040A = NORAD 44432 = Spektr-RG

Created 2019 Jul 22 17:06:25 UT using Find_Orb

Click here for an explanation of pseudo-MPECs

Click here for a more recent pseudo-MPEC, giving data since the object made a small maneuver and the resulting orbit.

This is a high-energy observatory (X-rays and gamma rays). It and its booster, 2019-040B are headed to the earth-sun L2 point (the one at opposition, about 1.5 million km out). Once there, Spektr-RG will make small maneuvers from time to time to maintain its place. The booster will pause there briefly, then enter heliocentric orbit.

Click here for some excellent information about this spacecraft. There is also the obligatory Wikipedia page for Spektr-RG.

The following ephemerides will become wrong when the spacecraft maneuvers. I don't know exactly when that will be, though almost certainly before the ephemerides run out.

Jost Jahn has produced a video showing both objects moving across the sky.

TLEs are available for this object and for the booster (and for most of the other objects listed on these pages.)
