Cool image time! The panorama above was created from four navigation camera images taken by the Mars rover Perseverance on April 10th. Because the lens on Perseverance’s navigation cameras produce slightly curved images which are taken in pairs, the panorama is made of two parts, each a pair perfectly matched images looking from a different angle. I have overlapped the pairs but as you can see, the match at the center is imperfect. While this does not produce a single smooth image, the two paired panoramas show the foot of the entire delta that had flowed into Jezero crater in the past and is the prime geological target of the rover. What is it made of? What caused it to flow into the crater? When did it do it? How was Mars different when it did so? Was the crater wet? Was the delta mud when it flowed, or was it sediment under water, pushed out by that flowing water?
The location map to the right is taken from the “Where is Perseverance?” webpage but annotated to show the planned routes of both Perseverance and Ingenuity, as shown by the tan dashed lines. The red dot marks Perseverance present location, the green dot Ingenuty’s. The yellow lines the approximate area covered by the panorama.
What next? Expect Perseverance to move as close to the base of the delta’s cliff as possible and spend at least several months studying it. Ingenuity meanwhile will be flown to the west to scout the various hollows that are potential routes for Perseverance to climb up onto the delta.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
