Yet it flies!!!

Your browser does not support HTML video. Ingenuity has successfully completed its first flight to Mars, a truly historic moment!On Earth, helicopters fly at a maximum altitude of 6 km, while Ingenuity flew in rarefied conditions that on Earth are only found above 36 km altitude!A “miracle”!!!

Ingenuity’s flight to Mars has been delayed until April 14 at the earliest

By Marco De Marco / April 12, 2021

Based on data from the Ingenuity helicopter that arrived late Friday night, NASA chose to reschedule the first experimental flight to no earlier than April 14. On Friday, during a high-speed rotor rotation test, the command sequence controlling the test ended early due to the “watchdog” timer. This occurred during an attempt to transition the flight computer from “Pre-Flight” mode to “Flight” mode. The helicopter is safe and sound and has reported its full telemetry to Earth. The “watchdog” timer oversees the sequence of commands and alerts the system to potential problems. The “watchdog” timer is a safety system that stops all flight procedures if a problem is detected and has worked as planned. The helicopter team is reviewing telemetry to diagnose and understand the problem. Subsequently, the test will be rescheduled to full speed.

Curiosity Sol 3082, April 8, 2021

At 02:30:30 UTC Mastcam Left captured a nice cloud formation crowding the Martian sky!Also for this Sol, this is not the only photo depicting a dense cloud formation (see https://mars.nasa.gov/msl/multimedia/raw-images/? order=sol+desc%2Cinstrument_sort+asc%2Csample_type_sort+asc%2C+date_taken+desc&per_page=50&page=0&mission=msl&begin_sol=3082&end_sol=3082&af=MAST_LEFT%7CMAST_RIGHT%2C%2C), confirming that the atmosphere contains an amount of water vapor far from the normally accepted values.Mars is approaching its maximum distance from the Sun (aphelion), period in which the planet has a temperature on average 20°C lower than when it reaches its maximum proximity to the Sun (perihelion) (see https://ilpianetamarte.org/Files/La_Temperatura_di_Marte/La_Temperatura_di_Marte.php). It is therefore normal that all the water evaporated during the hottest period at perihelion tends to condense into clouds as aphelion approaches.Mars is certainly drier than Earth, but clearly less arid than we think.The original image is a black and white encoding of the Bayer mask that has been converted to color through a process called “debayering” or “demosaicing”. In addition, the photo has undergone noise reduction due to Jpeg compression, white balance and a slight increase in microcontrast and color saturation in order to make the colors more similar to what the human eye would see.

At 15:14:09 LMST the Rear Left Hazcam captured an incredible Martian rainbow.I have never seen anything like it on Mars and I wonder if it could be a strange reflection between the lens or a real rainbow!Certainly it is the first time I see something like this and I am therefore more inclined to consider it “real”!If it was really a rainbow, this will become an “epochal” photo; the first rainbow photographed on another planet!!!Mars, who else???The original image underwent noise reduction due to compression, white balance and a slight increase in microcontrast and color saturation in order to make the colors more similar to what the human eye would see.

By Marco De Marco / April 3, 2021

At 21:25:23 UTC the Mastcam Left took again a nice formation of white clouds standing out in a clear blue Martian sky, this time also with a lot of gravity waves (see https://it.wikipedia.org/wiki/Onda_di_gravit%C3%A0). Also for this Sol, this is not the only photo that depicts a cloud formation (see https://mars.nasa.gov/msl/multimedia/raw-images/?order=sol+desc%2Cinstrument_sort+asc%2Csample_type_sort+asc%2C+date_taken+desc&per_page=50&page=0&mission=msl&begin_sol=3074&end_sol=3074&af=MAST_LEFT%7CMAST_RIGHT%2C%2C), a phenomenon that seems to occur frequently these days.The original image is a black and white encoding of the Bayer mask that has been converted to color through a process called “debayering” or “demosaicing”. In addition, the photo has undergone noise reduction due to Jpeg compression, white balance and a slight increase in microcontrast and color saturation in order to make the colors more similar to what the human eye would see.

InSight detects two more important earthquakes on Mars

By Marco De Marco / April 3, 2021

Two earthquakes, respectively of magnitude 3.3 and 3.1, have been recently recorded by the InSight lander as coming from the Cerberus Fossae region (see https://it.wikipedia.org/wiki/Cerberus_Fossae), already known for its geological peculiarities; note that InSight had already previously recorded another pair of earthquakes coming from Cerberus Fossae, then respectively of magnitude 3.6 and 3.5.As my personal curiosity, I add that Cerberus Fossae is also coincidentally located in an area of Mars where it is possible the formation of liquid water throughout the course of the Martian year (see https://www.facebook.com/PianetaMarte.MdM/photos/2027687353981114)!

Perseverance Sol 39, March 30, 2021

By Marco De Marco / March 31, 2021

At 14:16:49 LMST the SHERLOC WATSON camera captured the last phase of the deposition of the Ingenuity helicopter on Martian soil.Perseverance will have to move away from Ingenuity before it can charge its batteries and attempt its first flight, a flight that should take place in about a week.I remind you that flying a helicopter in such a nominally low atmospheric density is equivalent to flying a helicopter at an altitude of 36 km on Earth; I don’t know of any helicopter on Earth that has ever flown at such an altitude, not even close!I’m really looking forward to such a feat.The original image underwent a reduction in noise due to compression, white balance and a slight increase in microcontrast and color saturation in order to make the colors more similar to what the human eye would see.Finally, it was rotated 90° counterclockwise to correct its orientation.

At 14:00:07 UTC Mastcam Left captured a beautiful white cloud formation silhouetted against a clear Martian blue sky!Also for this Sol, this is not the only photo depicting a dense cloud formation (see https://mars.nasa.gov/msl/multimedia/raw-images/? order=sol+desc%2Cinstrument_sort+asc%2Csample_type_sort+asc%2C+date_taken+desc&per_page=50&page=1&mission=msl&begin_sol=3063&end_sol=3063&af=MAST_LEFT%7CMAST_RIGHT%2C%2C), proving that the humidity contained in the atmosphere is anything but negligible!In the lower left corner you will also notice the same rock imaged on Sol 3057 (see https://www.facebook.com/PianetaMarte.MdM/posts/3751059274977238).

The core of Mars has been measured and is surprisingly wide

By Marco De Marco / March 19, 2021

Mars has a molten core whose radius has been estimated at between 1810 and 1860 kilometers, about half that of Earth!NASA’s InSight probe has already recorded more than 500 earthquakes, of which more than fifty between magnitude 2 and magnitude 4.Thanks to these earthquakes it was possible to study for the first time the interior of the planet and thus reach the incredible discovery of the presence of a nucleus “melted” much larger than expected.Earthquakes, large molten core and large amounts of water trapped in the crust, does this seem the image of a dead planet?
