NASA’s Astronomy Picture of the Day for Oct. 3, 2026, features a Curiosity rover selfie made at Vera Rubin Ridge on Mars in January 2018. The 360-degree panorama combines 61 images, and NASA notes that Curiosity reached a cumulative elevation gain of 1 kilometer on Mount Sharp on Aug. 26, 2026.
NASA’s Astronomy Picture of the Day for Oct. 3, 2026, features a Curiosity rover selfie taken at the south rim of Vera Rubin Ridge on Mars. The image dates to Jan. 23, 2018, and its accompanying description reports a newer milestone: Curiosity had gained 1 kilometer in elevation during its climb from Gale Crater’s floor by Aug. 26, 2026.
The featured image is a mosaicked panorama assembled from 61 exposures recorded by Curiosity’s Mars Hand Lens Imager, or MAHLI. NASA says the rover took the images on sol 1943 of its mission. A sol is a Martian solar day, about 40 minutes longer than an Earth day; the date corresponding to this sol was Jan. 23, 2018.
To produce the selfie, frames that showed MAHLI’s extended arm were edited out. The panorama’s extended background came from Mastcam images taken on sol 1903, according to NASA. The result is also available as an interactive 360-degree virtual-reality panorama.
The view includes hardware and landscape details. NASA’s description says the ChemCam housing atop the rover’s mast blocks the distant peak of Mount Sharp, which rises about 5 kilometers. The Oct. 3 APOD credits the image to NASA, JPL-Caltech and MSSS, with the panorama credited to Andrew Bodrov.
A Record of Curiosity’s Climb
The APOD pairs an older image with a later update on Curiosity’s progress up Mount Sharp. The 1-kilometer elevation gain recorded on Aug. 26, 2026, gives readers a measure of how far the rover has climbed from the floor of Gale Crater. The selfie itself offers a view of the rover and its surroundings at one point in that longer journey.
The panorama also shows how mission images can combine observations made at different times. NASA identifies the 61 MAHLI exposures as coming from sol 1943, while the background was taken on sol 1903. That distinction matters when reading the image: it is a constructed panorama, not one exposure of the scene captured at a single moment.
The image is a NASA educational feature rather than an announcement of a new scientific discovery. Its news value is the combination of a dated record from Curiosity’s exploration with a current mission milestone included in the same published description.

From Gale Crater to the Ridge
Curiosity is a car-sized NASA rover exploring Gale Crater on Mars. Its route has taken it from the crater floor up the lower slopes of Mount Sharp, a prominent mountain inside the crater. Vera Rubin Ridge is a feature on that climb; the APOD identifies the selfie location as the ridge’s south rim.
The dates in the image caption refer to different events. Curiosity recorded the selfie on Jan. 23, 2018, corresponding to sol 1943. NASA’s separate elevation note says the rover reached a total gain of 1 kilometer from the crater floor on Aug. 26, 2026. The Oct. 3, 2026, publication date is the date the image appeared as APOD, not when the photograph was taken.
NASA’s Astronomy Picture of the Day service publishes an image or photograph with an explanation each day. For this entry, NASA lists the authors and editors as Jerry Bonnell, Cecilia Chirenti, Robert Nemiroff and Keighley Rockcliffe, and credits the service to NASA’s Astrophysics Science Division at Goddard, NASA Science Activation and Michigan Technological University.

What the Panorama Cannot Show
NASA’s APOD entry does not give further details about the elevation calculation, the rover’s precise position on Aug. 26, 2026, or the route remaining ahead. It also does not present the 1-kilometer figure as a new scientific finding; it is reported as a mission-progress milestone.
The panorama combines images from two sols, with arm frames removed and background imagery supplied by Mastcam. NASA’s description explains those edits but does not provide further technical details about image processing or the exact timing of every exposure. Readers should treat the view as an assembled panorama rather than a single unaltered photograph.

Curiosity’s Ongoing Mount Sharp Route
Curiosity’s exploration of Mount Sharp continues, but the APOD entry does not announce a specific upcoming destination, schedule or mission event. The next updates about the rover’s route and observations will depend on NASA mission communications. The Oct. 3 feature directs readers to the APOD submissions page for information about image submissions; it does not describe a change to the rover’s operations.

Key Questions
When did Curiosity take the Vera Rubin Ridge selfie?
Curiosity recorded it on sol 1943, which NASA gives as Jan. 23, 2018, on Earth’s calendar.
How was the selfie panorama made?
NASA says it combines 61 MAHLI exposures. Frames containing the imager’s arm were removed, and the extended background came from Mastcam imagery taken on sol 1903.
What does Curiosity’s 1-kilometer elevation gain mean?
NASA reports that by Aug. 26, 2026, Curiosity had gained 1 kilometer in elevation while traveling from the floor of Gale Crater up Mount Sharp’s slope. The APOD does not provide more detail about how the figure was calculated.
Is the picture a single photograph?
No. It is a mosaicked panorama made from multiple exposures, with background images from another sol. NASA also presents it as an interactive 360-degree virtual-reality image.
