Final flyby

Here is some data for a given UTC time. The data is obtained by interpolating the most up-to-date NAIF's files (the maximum interpolation error is shown next to the interpolated value) for the following coverage windows:
S/C h:           START: , END: 
S/C v:           START: , END: 
S/C r, lat, lon: START: , END: 
Sun r, lat, lon: START: , END: 
Bennu - Earth:   START: , END: 
S/C - Earth:     START: , END: 
S/C x axis:      START: , END: 
S/C z axis:      START: , END:

The graph shows the location of the spacecraft (S/C) and the Sun on the surface of Bennu. The latitude and the longitude are calculated as explained here.

h is the s/c altitude (m). Please, take a look here for further details.
r in the line "S/C" is the s/c radius vector (m) relative to Bennu, while r in the line "SUN" is Bennu radius vector (km). The interpolation error is calculated as the distance between the interpolated position and the NAIF position.
v is the s/c inertial speed wrt Bennu (mm/s).
Bennu - Earth and S/C - Earth are the distances (km) between the center of the bodies.



Here's the 3D version of the previous map in the Bennu-fixed rotating reference frame.
Blue dot: spacecraft; red dot: Nightingale; gray dot: Osprey; yellow line: Sun direction; magenta line: Earth direction.

S/C axes pointing direction (R.A., decl.; deg): X: Y: Z:

The interpolation error for the pointing direction is calculated as the maximum error between the right ascension error and the declination error. The right ascension error and the declination error are calculated as the difference between the interpolated value and the NAIF value.
The pointing direction of the x and z axes is obtained from the interpolation, while the pointing direction of the y axis is obtained from the cross product of z and x.


The interpolation error for the values used in the map (the first graph) is calculated as: interpolated_value - NAIF_value. For example, an altitude shown as "h: 642.0 -6.5/1.3" means that the interpolated altitude above the sub-spacecraft point can be anywhere between NAIF_altitude - 6.5 and NAIF_altitude + 1.3. In other words, the following inequality holds: 642 - 1.3 ≤ NAIF_altitude ≤ 642 + 6.5. Please, note that the interpolation error has nothing to do with the uncertainty.
Usually the error on the s/c longitude is negligible, but when the s/c approaches the polar regions, the error on the longitude can reach several degrees.
For the s/c - Earth distance, the average interpolation error is less than half the maximum error.

According to NAIF's rotational constants updated to 2021 Jan 14, the location of Bennu prime meridian (longitude = 0) is:
W = 150.48977 + 2011.143058731885 · d + 2 · 10-6 · d2
where d represents days past J2000 (TDB) and W is the angle shown here ("Body" is Bennu; X, Y and Z axes represent the Bennu body-fixed rotating coordinate system used for the calculations).
Bennu north pole coordinates are: RA= 85.45864 deg, DEC= -60.36468 deg.
