The HiRise camera on the Mars Reconnaissance Orbiter snapped a beautiful photo of Perseverance falling through the Martian atmosphere hanging from its parachute.
This photo is the latest entry in this catalog of "Images with caption".
This answer explains that the HiRise camera is a push broom type; it scans a 1D-like sensor across a long swath of Mars, like older photocopy machines and fax machines. I suppose this means it couldn't shoot a sequence of shots.

The image page says:
HiRISE was approximately 435 miles (700 kilometers) from Perseverance and traveling at about 6750 mile per hour (3 kilometers per second) at the time the image was taken. The extreme distance and high speeds of the two spacecraft were challenging conditions that required precise timing and for Mars Reconnaissance Orbiter to both pitch upward and roll hard to the left so that Perseverance was viewable by HiRISE at just the right moment.
Question: Why exactly did MRO have to "both pitch upward and roll hard to the left" to point exactly at Perseverance during the entry, descent and landing phase? What does that even mean?
Since the target object is tall and skinny, did it somehow have to maneuver to "pushbroom" horizontally so that the scan was across their short direction rather than bottom-to-top?
