When the rover stays in one place, it works quite well as a sundial, NASA says. You can see in the video listed below, posted on X, how the Sun and shadows cross Curiosity and the surrounding vistas. This is the very first time the Hazcams were utilized to tape 12 hours of images from a day on Mars.

The rover team back on Earth sent out the guidelines to tape-record the timelapse videos just before the start of Mars solar combination due to the fact that throughout this time, the Suns plasma hinders interactions between Earth and Mars. While the rover isnt totally out of contact, no complex guidelines are sent out during the numerous weeks of possible radio interference.
The Hazcams are normally used to identify rocks, slopes, and other hazards that may be dangerous for the rover to traverse. Due to the fact that Curiosity wasnt doing any roving or other science, the group hoped that by utilizing the Haxcams to record a day on Mars, they might be able to capture clouds or dust devils that might reveal more about the Red Planets weather condition. However, it was a fairly moderate weather day on Mars, so no unusual weather condition events show up in the video.
The Hazcams have an autoexposure algorithm to handle the numerous amounts of daylight at various parts of the day. Throughout mid-day, the algorithm settles on exposure times of around one-third of a second. By nightfall, that exposure time grows to more than a minute. This causes a common sensing unit sound understood as “hot pixels” that looks like white snow across the final image.
The video published on X reveals the very first part of the day, with images from the front Hazcam. The view looks southeast along Gediz Vallis, a valley discovered on Mount Sharp. Curiosity has actually been rising the base of the 3-mile-tall (5-kilometer-tall) mountain, which beings in Gale Crater, because 2014.

At dawn, the shadow of the rovers 7-foot (2-meter) robotic arm transfers to the left, and Curiositys front wheels emerge from the darkness on either side of the frame. Noticeable at left is a circular calibration target mounted on the shoulder of the robotic arm. Engineers utilize the target to check the precision of the Alpha Particle X-ray Spectrometer, an instrument that identifies chemical aspects on the Martian surface area.
The 2nd video, which is our lead animated gif image, shows the view of the rear Hazcam as it looks northwest down the slopes of Mount Sharp to the flooring of Gale Crater. The rovers best rear wheel shows up, together with the shadow of Curiositys power system. NASA explained that a little black artifact that appears at the left midway through the video, during the 17th frame, arised from a cosmic ray hitting the cam sensor. The bright flashing and other noise at the end of the video are the outcome of heat from the spacecrafts power system affecting the Hazcams image sensing unit.
How well does your own dozen-plus-year-old electronic camera work? NASA stated that speckled look of the images, especially popular in the rear-camera video, is due to 11 years of Martian dust deciding on the lenses. You can see in the image above how dust decides on many parts of the rover.
Interest launched from Earth on November 26, 2011 and arrived at August 4, 2012.
On November 8th, NASAs Curiosity Rover paused its incessant science work and simply viewed the day unfold on Mars. The rover used its black-and-white Hazard-Avoidance Cameras (Hazcams) to see a whole 12-hour day on Mars as the moving Sun cast shadows throughout the Martian landscape. NASA picked this day because of the Mars solar conjunction when the Sun interferes with interactions with the Red Planet, meaning the rover doesnt do any roving about. When the rover stays in one place, it works quite well as a sundial, NASA says. At dawn, the shadow of the rovers 7-foot (2-meter) robotic arm moves to the left, and Curiositys front wheels emerge from the darkness on either side of the frame.
Throughout solar conjunction, I utilized my danger cams to study the Martian weather and dust. As this Earth year comes to an end, I hope youll take the time to soak in whats around you.
On November 8th, NASAs Curiosity Rover paused its constant science work and simply enjoyed the day unfold on Mars. NASA selected this day due to the fact that of the Mars solar conjunction when the Sun interferes with communications with the Red Planet, implying the rover doesnt do any roving about.
