Sols 4464-4465: Making Good Progress
NASA’s Mars rover Curiosity acquired this image using its Front Hazard Avoidance Camera (Front Hazcam) on Feb. 23, 2025 — sol 4462, or Martian day 4,462 of the Mars Science Laboratory mission — at 21:43:37 UTC.

Earth planning date: Monday, Feb. 24, 2025
Over the weekend Curiosity drove about 48 meters (about 157 feet) to the southwest, continuing to march along on our traverse past Texoli butte and Gould Mesa. I was on shift as the LTP today, and it was great to see the good drive progress, interesting workspace, and exciting stratigraphy that lies ahead.
Today’s two-sol plan includes contact science and a drive on the first sol, followed by untargeted remote sensing on the second sol. The Geology theme group got straight to work evaluating contact science targets, and decided on a nodular block named “Matilija Poppy” for APXS and MAHLI observations. Then the team turned their attention to the remote sensing activities. There are a variety of interesting rock textures near the rover, so the team spent some time planning Mastcam imaging and ChemCam LIBS activities to assess the diversity. Some blocks have polygonal fractures with raised ridges, while other blocks are more nodular or well-laminated. In addition to looking at the bedrock, Mastcam will document local troughs in the loose sand between blocks, to understand more recent surface processes. The team planned a ChemCam LIBS observation on one of the polygonal fractures at a target named “East Fork” and two long-distance ChemCam RMI mosaics of Gould Mesa to assess the distant stratigraphy. Then Curiosity will drive about 30 meters (about 98 feet) further to the south, and take post-drive imaging to prepare for Wednesday’s plan.
On the second sol Curiosity will take an autonomously selected ChemCam target, along with multiple environmental monitoring observations to search for dust devils, monitor atmospheric dust, and evaluate clouds. It was a pretty smooth day of planning, and it’s always nice to see how the team works together to accomplish a lot of great science. Looking forward to continuing to make great progress as we start climbing uphill again!

4 Min Read Science in Orbit: Results Published on Space Station Research in 2024
NASA and its international partners have hosted research experiments and fostered collaboration aboard the International Space Station for over 25 years. More than 4,000 investigations have been conducted, resulting in over 4,400 research publications with 361 in 2024 alone. Space station research continues to advance technology on Earth and prepare for future space exploration missions.
Below is a selection of scientific results that were published over the past year. For more space station research achievements and additional information about the findings mentioned here, check out the 2024 Annual Highlights of Results.
Making stronger cement
NASA’s Microgravity Investigation of Cement Solidification (MICS) observes the hydration reaction and hardening process of cement paste on the space station. As part of this experiment, researchers used artificial intelligence to create 3D models from 2D microscope images of cement samples formed in microgravity. Characteristics such as pore distribution and crystal growth can impact the integrity of any concrete-like material, and these artificial intelligence models allow for predicting internal structures that can only be adequately captured in 3D. Results from the MICS investigation improve researchers’ understanding of cement hardening and could support innovations for civil engineering, construction, and manufacturing of industrial materials on exploration missions.

The JAXA (Japan Aerospace Exploration Agency) Colloidal Clusters investigation uses the attractive forces between oppositely charged particles to form pyramid-shaped clusters. These clusters are a key building block for the diamond lattice, an ideal structure in materials with advanced light-manipulation capabilities. Researchers immobilized clusters on the space station using a holding gel with increased durability. The clusters returned to Earth can scatter light in the visible to near-infrared range used in optical and laser communications systems. By characterizing these clusters, scientists can gain insights into particle aggregation in nature and learn how to effectively control light reflection for technologies that bend light, such as specialized sensors, high-speed computing components, and even novel cloaking devices.

NASA’s Optical Imaging of Bubble Dynamics on Nanostructured Surfaces studies how different types of surfaces affect bubbles generated by boiling water on the space station. Researchers found that boiling in microgravity generates larger bubbles and that bubbles grow about 30 times faster than on Earth. Results also show that surfaces with finer microstructures generate slower bubble formation due to changes in the rate of heat transfer. Fundamental insights into bubble growth could improve thermal cooling systems and sensors that use bubbles.

The ESA (European Space Agency) investigation Cytoskeleton attempts to uncover how microgravity impacts important regulatory processes that control cell multiplication, programmed cell death, and gene expression. Researchers cultured a model of human bone cells and identified 24 pathways that are affected by microgravity. Cultures from the space station showed a reduction of cellular expansion and increased activity in pathways associated with inflammation, cell stress, and iron-dependent cell death. These results help to shed light on cellular processes related to aging and the microgravity response, which could feed into the development of future countermeasures to help maintain astronaut health and performance.

The CSA (Canadian Space Agency) investigation Wayfinding investigates the impact of long-duration exposure to microgravity on the orientation skills in astronauts. Researchers identified reduced activity in spatial processing regions of the brain after spaceflight, particularly those involved in visual perception and orientation of spatial attention. In microgravity, astronauts cannot process balance cues normally provided by gravity, affecting their ability to perform complex spatial tasks. A better understanding of spatial processes in space allows researchers to find new strategies to improve the work environment and reduce the impact of microgravity on the spatial cognition of astronauts.

The Roscomos-ESA-Italian Space Agency investigation Mini-EUSO (Multiwavelength Imaging New Instrument for the Extreme Universe Space Observatory) is a multipurpose telescope designed to examine light emissions entering Earth’s atmosphere. Researchers report that Mini-EUSO data has helped to develop a new machine learning algorithm to detect space debris and meteors that move across the field of view of the telescope. The algorithm showed increased precision for meteor detection and identified characteristics such as rotation rate. The algorithm could be implemented on ground-based telescopes or satellites to identify space debris, meteors, or asteroids and increase the safety of space activities.

The ARCSTONE observatory is shown in low Earth orbit with the spectrometer viewing the Sun and Moon. The spacecraft rotates in order to view the Moon or the Sun. One of the most challenging tasks in remote sensing from space is achieving required instrument calibration accuracy on-orbit. The Moon is considered to be an excellent exoatmospheric calibration source. However, the current accuracy of the Moon as an absolute reference is limited to 5 – 10%, and this level of accuracy is inadequate to meet the challenging objective of Earth Science observations. ARCSTONE is a mission concept that provides a solution to this challenge. An orbiting spectrometer flying on a small satellite in low Earth orbit will provide lunar spectral reflectance with accuracy sufficient to establish an SI-traceable absolute lunar calibration standard for past, current, and future Earth weather and climate sensors.
