NASA’s Astronomy Picture of the Day for Oct. 3, 2026, features a Curiosity rover selfie taken at Vera Rubin Ridge on Mars in January 2018. The panorama combines 61 rover images, and NASA’s description notes that Curiosity had accumulated 1 kilometer of elevation gain on Mount Sharp by Aug. 26, 2026.
NASA’s Astronomy Picture of the Day for Oct. 3, 2026, features a Curiosity rover selfie taken at Vera Rubin Ridge on Mars. The image was recorded on Jan. 23, 2018, during the rover’s sol 1,943, while the accompanying description reports that Curiosity had gained 1 kilometer in elevation during its ascent from Gale Crater’s floor by Aug. 26, 2026.
The featured picture is a mosaicked panorama made from 61 exposures taken with Curiosity’s Mars Hand Lens Imager, or MAHLI. NASA says the rover was at the south rim of Vera Rubin Ridge when it recorded the images. The APOD entry also says an interactive 360-degree VR version was made from the panorama.
NASA’s description explains that frames showing MAHLI’s arm were edited out. The extended background in the composition came from the rover’s Mastcam, photographed on sol 1,903. A housing for the ChemCam instrument, mounted above the Mastcam on the rover’s mast, obscures the distant peak of Mount Sharp in the view.
The image dates to 2018, not to the day the APOD was published. NASA identifies sol 1,943 as Earth date Jan. 23, 2018. A sol is a Martian solar day, which the entry says is about 40 minutes longer than an Earth day. The later elevation milestone is separately dated Aug. 26, 2026.
A Long Climb Through Gale Crater
The APOD pairs a view of Curiosity at a specific point on its route with a later marker of the rover’s progress. Its reported 1-kilometer elevation gain puts the 2018 selfie within a longer account of the mission’s ascent from Gale Crater’s floor toward Mount Sharp. The post does not claim that the selfie itself documents the 2026 milestone; the dates are more than eight years apart.
For readers, the distinction illustrates how NASA uses both images and mission measurements to document exploration over time. The panorama shows the rover and surrounding terrain, while the elevation figure provides a compact measure of how far it has climbed vertically since starting from the crater floor. The source does not give a route distance or a rate of ascent, so the kilometer figure should be understood as elevation gain, not distance traveled.

How the 2018 Panorama Was Made
NASA’s APOD is a daily feature that presents an image or photograph of the universe with an explanation written by a professional astronomer. The Oct. 3 entry identifies the image credits as NASA, the Jet Propulsion Laboratory, the California Institute of Technology and Malin Space Science Systems. It lists Andrew Bodrov for the panorama and names Jerry Bonnell, Cecilia Chirenti, Robert Nemiroff and Keighley Rockcliffe as authors and editors.
Curiosity’s selfie is a composite rather than a single exposure. MAHLI supplied the 61 images used for the rover-centered mosaic, while Mastcam provided the extended background from an earlier sol. Removing frames that included the imaging arm helps create the appearance of a more unobstructed portrait. The source describes the ChemCam housing as blocking the distant, 5-kilometer-high peak of Mount Sharp.
The entry gives two different time references: the selfie’s Earth date in 2018 and the elevation-gain milestone in 2026. Keeping those dates separate matters because the October 2026 APOD republishes and explains an older mission image; it is not a newly captured photograph.
Limits of the APOD Update
The NASA entry gives the rover’s cumulative elevation gain as of Aug. 26, 2026, but does not provide a more recent figure or say whether Curiosity has gained additional elevation since that date. It also does not specify the rover’s elevation at the time of the 2018 selfie, the route distance associated with the climb, or a target elevation for the mission.
The APOD is an image feature and brief explanation, not a detailed mission-status report. Its description does not include new scientific results from the ridge, discuss the rover’s current condition, or set out a future schedule. Those details cannot be established from this source alone.
Future Curiosity Mission Updates
NASA’s Oct. 3 feature presents the 2018 panorama and reports the elevation milestone through Aug. 26, 2026. The source does not announce a new Curiosity maneuver, destination, or mission event. Any further progress, science findings or changes in the rover’s status would need to be confirmed through subsequent NASA mission updates.
Readers can view the APOD image and its explanation through NASA Science. The page also notes a change to the email address for image submissions, but that administrative notice is separate from Curiosity’s exploration and does not alter the reported dates or measurements.
Key Questions
When did Curiosity take the Vera Rubin Ridge selfie?
NASA dates the image to sol 1,943, corresponding to Jan. 23, 2018, on Earth.
How many images make up the panorama?
The panorama combines 61 MAHLI exposures. NASA says the background was extended with Mastcam imagery taken on sol 1,903.
What does the 1-kilometer figure describe?
It is Curiosity’s total elevation gain on its trek from the floor of Gale Crater up the slope of Mount Sharp, reported as of Aug. 26, 2026. It is not a measure of route distance.
Was the selfie taken in October 2026?
No. Oct. 3, 2026 is the APOD publication date. The selfie was recorded on Mars in January 2018.
