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.

I can't wait to see the images and/or video from the helicopter. I hope it ventures into some of the canyons.

Hope you're all ready for another seven minutes of terror prior to a (hopefully) successful landing of NASA's latest Martian SUV (Perseverance Rover)! Following in the footsteps of Curiosity, "Percy" will mark the next chapter of Mars Exploration with lots of new capabilities and feats.
Touchdown on the surface of Mars is planned for Feb 18,2021 at 12:55 p.m. PST. The Live-Feed will be available via the NASA-TV Livestream on YouTube below:
The next couple of hours, days, weeks etc. will be quite exciting (provided that all goes well during the EDL phase, meaning: Entry, Descent and Landing).
All about the science, the instruments aboard the rover and the objectives of NASA's Mars 2020 mission can be found here. Among the many new things this mission introduces, it should be highlighted that Percy will carry a helicopter drone called "Ingenuity", which will be deployed in the rover's vicinity to inspect the surrounding terrain and take aerial shots of the Martian landscape.

PAST LIFE ON MARS?
Another exciting aspect is that the rover is officially on an astrobiology mission (in contrast to her predecessor "Curiosity"). This means that looking for biosignatures of ancient life on Mars is one of the mission objectives. As many of you know, interesting things have been spotted on Mars during previous missions. However, it was never unambiguous what has been imaged, even if something looked really organic in nature, being quite reminiscent of terrestrial fossils (also see here for a collection of anomalous features found on the Martian surface over the years). I'm linking some other related ATS threads further below for those interested.
So what can we expect from this mission? I, for one, keep my fingers crossed that this will be a successful endeavour, that's for sure. But feel free to chime in with any thoughts you might have regarding Percy's upcoming space adventure!
Exciting times ahead, indeed. So "Godspeed", Perseverance. Have a safe landing and a jolly good time on Mars!
