Curiosity Blog, Sols 4920-4926: Surveying the Bands NASA’s Mars rover Curiosity acquired this image of small butte, “Miraflores,” using its Mast Camera (Mastcam) on June 11, 2026 — Sol 4922, or Martian day 4,922 of the Mars Science Laboratory mission — at 09:12:13 UTC. NASA/JPL-Caltech/MSSS
Written by William Farrand, Senior Research Scientist, Space Science Institute
Earth planning date: Friday, June 12, 2026
Rather than going from stage to stage at a music festival to hear different bands playing different varieties of music, Curiosity has been ascending up Mount Sharp through physical bands of exposed rocks with textural and tonal differences.
Planning for sols 4920 and 4921 were done with the rover in the middle of a unit with a rougher texture and dark-toned bedrock. With the rougher-textured bedrock, brushing wasn’t possible, but APXS chemistry and MAHLI micro-imaging were planned on “as is” bedrock targets “Salto La Cascada” and “Puerto de Rosas.” ChemCam was targeted to perform LIBS spectroscopy on a bedrock target “Kishuara” and a small, layered float rock “La Rosita.” ChemCam’s Remote Micro-Imager (RMI) collected views of the “Mishe Mokwa” butte and another looking at dunes with tonal differences. Mastcam mosaics were collected on the “Valle Grande” channel, “Kimsa Chata” butte, nearby troughs, and the aircraft carrier shaped rock “El Matir.”
Another drive brought Curiosity closer to the upper border of the dark-toned band. Again, brushing of the rocks was not possible, but APXS and MAHLI were collected on dark-toned bedrock targets “Santa Gracia” and “Laguna San Rafael” with ChemCam LIBS also targeting the bedrock. Mastcam mosaics were collected of a layered rock and nearby troughs and a mosaic of the nearby smaller butte, “Miraflores” which displays an interesting layered structure with ragged dark-toned rocks on one side and a stack of dust piled on top (see accompanying image). Other activities included a long-distance RMI mosaic of a bright unit on “Mishe Mokwa”, and Navcam dust-devil surveys in both sols.
Communicating between Earth and Mars has come to seem routine, but at times can still be a challenging endeavor and this was demonstrated to the team on Friday when we did not get a timely downlink of data for the drive planned for Sol 4923. Without these images another drive, in situ examinations, or targeted remote sensing could not be planned. However, there are always interesting things to be done on Mars and the three-sol plan (4924 to 4926) included a 360-degree Mastcam mosaic, the automatic AEGIS targeting of LIBS measurements on each sol, a Navcam dust-devil survey, APXS atmospheric measurements, as well as several other environmental activities.
On Monday, the delayed downlink will be used to plan the first investigation of the next band of surface materials, this one being smooth-textured and light-toned, as well as another drive to continue the surveying of the bands.

NASA Mission to Study Space Weather Impacts of Earth’s Atmosphere
NASA selected a mission concept to research how space weather and dynamics within Earth’s atmosphere influence the space environment and help improve prediction capabilities for impacts on crucial technology, such as GPS and low Earth orbit satellites, as well as astronauts in space.
The DAPHNE (Dynamic Atmosphere-Ionosphere Explorer) mission will enter Phase B of development, which includes planning and design for flight and mission operations. It will use identical twin satellites to study how changes in Earth’s lower atmosphere influence our planet’s upper atmosphere, where space weather is manifested.
“NASA is advancing the United States’ leadership as a space weather-ready nation, and by providing new insights into Earth’s atmosphere we can better predict and prepare for impacts in our daily lives on Earth and in space,” said Nicky Fox, associate administrator, Science Mission Directorate, NASA Headquarters in Washington. “As NASA sends astronauts beyond Earth’s magnetic protection to the Moon, Mars, and beyond, DAPHNE will join the NASA science fleet strategically located across the solar system to provide data that will help mission planners predict and mitigate the effects of space weather for the benefit of all.”
The DAPHNE mission’s low-risk high-return concept will provide coordinated, multi-point measurements of neutral winds, temperature, and composition in the thermosphere. The ionosphere and thermosphere regions are where Earth’s neutral atmosphere transitions into the ionized plasma of space. In this thin shell that surrounds the planet, the atmosphere is in constant motion, shaped by the influence of solar activity and changes in the lower atmosphere and in near-Earth space.
Fundamental observations and physical insights from the DAPHNE mission will incorporate lower-atmospheric energy data to advance space weather predictive capabilities. The mission is led by Aimee Merkel from the Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder.
The mission will be subject to a confirmation review in 2027, which will assess the progress of the mission and the availability of funds. If confirmed, the total estimated cost of the mission, excluding launch, will not exceed $250 million in fiscal year 2023 dollars, with a mission launch date of no earlier than 2029.
The DAPHNE mission was proposed as a concept study in response to the DYNAMIC (Dynamical Neutral Atmosphere-Ionosphere Coupling) mission announcement of opportunity. Funding and management oversight for this mission is provided by the Solar Terrestrial Probes program at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
