Sample return
Here is some data related to the OSIRIS-REx sample return phase obtained by interpolating the original data files for the following coverage windows (times are given in TDB):
S/C - SUN : START: , END:
S/C x axis : START: , END:
S/C z axis : START: , END:
Mercury : START: , END:
Venus : START: , END:
Earth : START: , END:
Bennu : START: , END:
Here's the S/C axes pointing direction in the mean ecliptic and equinox of J2000 reference frame.
The solid lines represent the S/C axes and the dashed lines represent the direction of the Earth and the Sun.
Interpolation errors (deg):
X:
Y:
Z:
The interpolation error is calculated as the angular separation between the true direction (obtained from the NAIF's data files and SPICE library) and the interpolated direction.
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 graph helps in finding the time (TDB) when the S/C varies its attitude. It shows the magnitude of the S/C angular velocity in the mean ecliptic and equinox of J2000 reference frame.
