Update on Ingenuity
Click for interactive map.
The overview map above shows the travels of both the rover Perseverance and the helicopter Ingenuity on Mars through today, with the blue dot marking Perseverance’s present location and the green dot Ingenuity’s. Because of image downloads today from Perseverance — including a few more pictures taken by the helicopter during several of its recent flights — the helicopter’s engineering team has finally been able to add the flight paths for flights #68, #69, and #70 to this map, as well as provide more accurate information about what each accomplished..
Flight #68, which took place on December 15, 2023, a few days later than originally planned, as I reported on December 20, 2023 when the first preliminary data arrived. At the time it appeared the flight had ended prematurely by almost 1,500 feet. We now know the flight did end early, but by not that much. Instead of flying, as per its flightplan, to the northeast 2,716 feet for 147 seconds and then returning to its take-off point, it flew out and back 2,304 feet for 131 seconds. The engineering team has not explained why it turned around prematurely by about 200 feet.
Flight #69 on December 20, 2023 was supposed fly 2,304 feet total over 131 seconds, also going out and back, traveling to the east-northeast. It ended up flying 2,315 feet over 135 seconds on a flight path that was almost identical to flight #68. Like most previous flights, it appears it hovered over its landing spot for a few extra seconds before descending in order to make sure it would land safely.
The final numbers for flight #70 have not yet been added to the flight log, but the engineering team has apparently been able to figure out the path the helicopter took and where it landed from the images that have been downloaded in the past few days. The flight plan had called for a relatively short flight, 849 feet long, but taking almost as long as the previous two, 129 seconds, thus allowing Ingenuity to get better and more detailed scouting pictures of the terrain below it for scientists to review.
One more detail: It appears that the Perseverance science team has decided to use Ingenuity data to guide its route. Rather than follow the planned course, as indicated by the red dotted line, the rover has been following the ground scouted by Ingenuity on its 63rd flight on October 19, 2023. This has taken Perseverance deeper into the rough fractured terrain to the south, where it likely can obtain better geological data.
It also suggests that Ingenuity’s more recent flight paths are giving us a hint as to Perseverance’s future travels.
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
