Playing around with the latest SPICE kernels posted to the public NAIF website shows two points in the MSL landing sequence where the HiRISE camera is pointed directly at MSL. I made a couple visualizations:
The red dot is MSL. The field of view of the images is 30° while the HiRISE fov is 1.15°. MRO's pointing direction is taken to be HIRISE_OPTICAL_AXIS. According to the kernel data, the landing occurs at 05:17:54 UT, so apparently the advertised landing time of 05:31 is Earth-received time. The images show when HIRISE_OPTICAL_AXIS intersects the position of MSL. -------------------- |
