NASA’s Astronomy Picture of the Day for October 3, 2026, features a Curiosity rover selfie taken at Vera Rubin Ridge on Jan. 23, 2018. The panorama combines 61 images, and NASA’s description notes that Curiosity had gained 1 kilometer in elevation on Mount Sharp by Aug. 26, 2026.
NASA’s Astronomy Picture of the Day for October 3, 2026, features a panoramic selfie of the Curiosity rover at the south rim of Vera Rubin Ridge on Mars. The image was recorded on Jan. 23, 2018, during the rover’s 1,943rd Martian day, and the accompanying NASA description reports that Curiosity had gained 1 kilometer in elevation on its climb from Gale Crater’s floor by Aug. 26, 2026.
The image is a mosaic of 61 exposures taken by Curiosity’s Mars Hand Lens Imager, or MAHLI. NASA says frames showing the camera’s robotic arm were edited out of the composite. The extended background was photographed separately by the rover’s Mastcam on sol 1903, 40 sols before the selfie session.
In the picture, the rover’s mast rises above its deck. The ChemCam housing, mounted at the top of the mast above the Mastcam, blocks the distant summit of Mount Sharp from view. NASA describes Mount Sharp as a peak about 5 kilometers high. The image was also composed as an interactive 360-degree virtual-reality panorama, according to the APOD description.
NASA’s date conversion places sol 1943 on January 23, 2018, on Earth. A Martian sol is a solar day that lasts about 40 minutes longer than an Earth day. The rover’s later elevation figure refers to its ascent over the course of its trek, rather than to a new photograph or a measurement made on the day the APOD was published.
A Long Climb on Mount Sharp
The APOD pairs an older image with a later measure of Curiosity’s progress, giving readers a visual record of a rover that has spent years examining the layered terrain of Gale Crater. The reported 1-kilometer elevation gain offers a simple measure of the scale of its route from the crater floor up Mount Sharp’s slope.
The milestone is relevant because Curiosity’s mission is not simply to travel across Mars: it studies rocks and terrain along its route. NASA’s description connects the selfie to the rover’s continuing climb, but does not attribute a new scientific discovery to the image or the elevation figure. The photograph is chiefly a record of the rover and its surroundings at a particular point in that journey.

From Sol 1943 to 2026
NASA’s APOD service presents a different astronomical image or photograph each day alongside an explanation written by a professional astronomer. Its October 3, 2026, entry revisits a Curiosity panorama from Vera Rubin Ridge, a feature on the rover’s route up Mount Sharp in Gale Crater. The date in the APOD title is the publication date, not the date the image was taken.
Curiosity recorded the selfie on sol 1943; the background Mastcam frames came from sol 1903. Those separate sets of exposures were combined to form the panorama. NASA credits the image to NASA, the Jet Propulsion Laboratory, the California Institute of Technology and MSSS, and credits the panorama to Andrew Bodrov. The APOD entry lists Jerry Bonnell, Cecilia Chirenti, Robert Nemiroff and Keighley Rockcliffe as authors and editors.
The description adds a later mission marker: NASA says Curiosity had accumulated a total elevation gain of 1 kilometer in its journey from Gale Crater’s floor by Aug. 26, 2026. That statement places the older selfie within the rover’s longer ascent; it does not say that the rover climbed the full kilometer after taking the picture.

Limits of the APOD Update
The APOD entry does not provide a new rover-status report, a detailed route map or a breakdown of how NASA calculated the 1-kilometer elevation gain. It gives the milestone’s date and broad reference points—the floor of Gale Crater and the slope of Mount Sharp—but not the rover’s exact location on Aug. 26, 2026, or its elevation above a stated reference level.
The description also does not identify any new scientific results associated with the selfie or explain what Curiosity was investigating at that precise site. The confirmed development here is the publication of the image and its accompanying description, not a newly announced mission finding. The source material does not specify the rover’s next planned stop or the timing of a subsequent milestone.

Further Curiosity Mission Updates
The APOD entry does not announce a future waypoint, schedule or new mission milestone. Readers seeking later progress will need to rely on subsequent NASA mission updates; this image itself is a retrospective view from 2018 paired with a status figure dated Aug. 26, 2026.
NASA’s page also notes that the email address for APOD image submissions has changed and directs contributors to its APOD Submissions information. That administrative note is separate from Curiosity’s mission progress. No additional rover activity or next publication is specified in the source.

Key Questions
When did Curiosity take the Vera Rubin Ridge selfie?
Curiosity recorded it on sol 1943, which NASA maps to January 23, 2018, on Earth.
How was the panorama made?
NASA says the mosaic combines 61 MAHLI exposures. Frames containing the camera arm were edited out, and the extended background came from Mastcam images taken on sol 1903.
What does the 1-kilometer figure describe?
It is Curiosity’s total elevation gain on its trek from Gale Crater’s floor up Mount Sharp’s slope, as reported for August 26, 2026. NASA’s APOD description does not give a detailed calculation or exact rover position for that date.
Is the selfie a newly taken image?
No. The APOD was published on October 3, 2026, but the selfie was recorded in 2018. The later elevation milestone is separate context, not the image’s capture date.
