Curiosity Blog, Sols 4629-4630: Feeling Hollow NASA’s Mars rover Curiosity acquired this image of its workspace, including the small crescent-shaped rock named “Wedge Tailed Hillstar,” visible in the image just above the letters “SI” written on Curiosity’s arm. Curiosity captured the image using its Left Navigation Camera on Aug. 13, 2025 — Sol 4628, or Martian day 4,628 of the Mars Science Laboratory mission — at 08:54:46 UTC. NASA/JPL-Caltech

Earth planning date: Wednesday, Aug. 13, 2025

Today’s team investigated the texture and chemistry of the bedrock within a topographic low, or hollow, found within the greater boxwork area. We will place our APXS instrument on the “Asiruqucha” target, some light-toned, small-scale nodular bedrock in the middle of our workspace. These data will help illuminate any systematic chemical trends between the hollows and ridges in this area. We always take an associated MAHLI image with every APXS measurement to help contextualize the chemistry. We will also observe a small crescent-shaped rock named “Wedge Tailed Hillstar” with MAHLI, visible in the above Navcam image just above the letters “SI” written on Curiosity’s arm.

We will use our remote sensing instruments to continue documenting the region taking stereo Mastcam images of “Cerro Paranal,” “Rio Frio,” and “Anchoveta.”  The ChemCam instrument will take an image of, and collect chemical information for, the target “Camanchaca,” as well as use its Remote Micro Imager (RMI) to take high-resolution imaging of more distant boxwork features. 

Once these observations are completed Curiosity will set off on a 30-meter drive (about 98 feet), taking us to an interesting ridge feature to investigate in Friday’s plan.

As usual we will continue to take our regular atmospheric monitoring observations using REMS, RAD, and DAN.

Space is getting dangerously crowded but a new automated system could be the key to preventing catastrophic collisions that threaten our satellites and astronauts. The European Space Agency has developed CREAM (Collision Risk Estimation and Automated Mitigation), a revolutionary technology that aims to transform how we manage traffic in Earth orbit and keep space safe for future generations.

arXiv:2507.21402v1 Announce Type: new Abstract: The interstellar object 3I/ATLAS is expected to arrive at a distance of $53.56(\pm 0.45)$ million ${\rm km}$ ($0.358\pm 0.003$~au) from Jupiter on March 16, 2026. We show that applying a total thrust $\Delta$V of $2.6755{{\rm km~s^{-1}}}$ to lower perijove on September 9, 2025 and then execute a Jupiter Oberth Maneuver, can bring the Juno spacecraft from its orbit around Jupiter to intercept the path of 3I/ATLAS on March 14, 2026.
