Earth planning date: Thursday, July 3, 2025

The team was delighted this morning to learn that Wednesday’s drive had completed flawlessly, placing us in a stable position facing a ~3 foot high ridge located ~35 feet away.  This ridge is the eastern edge of a feature the team has informally named “Volcán Peña Blanca.” This feature certainly looked intriguing in orbital images, but once we saw Curiosity’s pictures of it from the ground, we decided it was cool enough to spend the time to investigate it closer.  The images from the ground show a lot more detail than is visible in orbit, including clear sedimentary structures exposed along the ridge face which could provide important clues about how the rocks in the boxwork-bearing terrain were initially deposited – dunes? Rivers? Lakes? The team picked their favorite spot to approach the ridge and take a closer look during Wednesday’s planning, so Curiosity made a sharp right turn to take us in that direction.  Using today’s images, we refined our plan for the exact location to approach and planned a drive to take us there, setting us up for contact science on Monday.

We had the opportunity to plan four sols today, to cover the U.S. 4th of July holiday weekend, so there was lots of time for activities besides the drive.  Curiosity is currently sitting right in front of some light toned rocks, including one we gave the evocative name “Huellas de Dinosaurios.” It’s extremely unlikely we’ll see dinosaur footprints in the rock, but we will get the chance to investigate it with APXS, MAHLI, and ChemCam.  We also have a pair of ChemCam only targets on a more typical bedrock target named “Amboro” and some pebbles named “Tunari.”  Mastcam will take a high resolution of mosaic covering Volcán Peña Blanca, some nearby rocks named “Laguna Verde,” a small light colored rock named “Suruto,” and various patterns in the ground. Two ChemCam RMI mosaics of features in the distant Mishe Mokwa face and environment monitoring activities round out the plan.

Earth planning date: Wednesday, July 2, 2025

As we traverse the boxwork terrain, we are encountering a series of more resistant ridges/bedrock patches, and areas that are more rubbly and tend to form lower relief polygonal or trough-like features. We came into planning this morning in one of the trough-like features after another successful drive. The science team is interested in determining why we see these different geomorphological and erosional expressions. Is the rock that comprises the more resistant ridges and patches a different composition to the rock in the troughs and low relief areas? How do the rocks vary texturally? Might the resistant bedrock be an indicator of what we will encounter when we reach the large boxworks that we are driving towards?

We managed to find a large enough area of rock to safely brush (target – “Guapay”), after which we will place APXS and MAHLI to determine the composition and texture. ChemCam will also analyze a different rock target, “Taltal” for chemistry and texture, and we will also acquire an accompanying Mastcam documentation image. The resistant ridge that we are planning to drive towards (“Volcan Pena Blanca”) and eventually investigate will be captured in a Mastcam mosaic. ChemCam will utilize their long-distance imaging capabilities to image the “Mishe Mokwa” butte off to the southeast of our current location, which likely contains bedrock layers that we will eventually pass through as we continue our climb up Mount Sharp.

After a planned drive, taking us closer to the “Volcan Pena Blanca” ridge, MARDI will image the new terrain beneath the wheels, before we execute some atmospheric observations. Mastcam will make a tau observation to monitor dust in the atmosphere and Navcam will acquire a zenith movie. Standard DAN, RAD and REMS activities round out the plan.

The Expedition 73 crew kicked off the week studying electrical muscle stimulation and cellular immunity to protect crew health in microgravity. The orbital residents are also unpacking a new cargo craft and continuing to support the Axiom Mission 4 (Ax-4) crew aboard the International Space Station.

NASA Flight Engineers Nichole Ayers and Anne McClain joined each other in the Columbus laboratory module on Monday and explored stimulating muscles with small electrical signals to help prevent space-caused muscle atrophy. Ayers wore electrodes as McClain operated biomedical gear sending electrical impulses to her legs simulating load forces on the ground. Researchers are exploring electrical muscle stimulation to supplement daily space workouts and keep astronauts fit in weightlessness.

Ayers then partnered with NASA Flight Engineer Jonny Kim assisting him as he inspected hatches in the Quest airlock and the Harmony module and downlinked photographs for further analysis by engineers on the ground. Kim began his day in the Tranquility module replacing orbital plumbing components then switched over to the Destiny laboratory module and swapped out research hardware.

Station Commander Takuya Onishi from JAXA (Japan Aerospace Exploration) began his shift with a standard cognition test then documented his meals and medication for the day. Afterward, Onishi set up computer hardware that supports the advanced resistive exercise device then collected his saliva samples for stowage in the Kubik incubator and later analysis to study cellular changes in microgravity.

Before she assisted Ayers, McClain serviced spacesuit life support gear then checked cable connections on a computer that supports the MUSES commercial Earth observation hardware. McClain also worked throughout the day supporting the Ax-4 crew members as they conducted their private research.

Veteran astronaut and Ax-4 Commander Peggy Whitson spent Monday assisting her Ax-4 crewmates Shubhanshu Shukla, Sławosz Uznański-Wiśniewski, and Tibor Kapu during their busy day of space experiments. The quartet explored a wide array of subjects including space agriculture to provide fresh food for crews, how blood circulates in space, a human-computer interface, and more on Monday.

The new Progress 92 cargo craft is being unloaded today after its docking to the Poisk module on Saturday, July 5. Roscosmos Flight Engineers Sergey Ryzhikov and Alexey Zubritskiy opened Progress’ hatch on Sunday and continued working into Monday transferring some of its three tons of food, fuel, and supplies into the orbital outpost. Ryzhikov later activated a camera pointed at Earth that students will remotely control for a weeklong observation session. Flight Engineer Kirill Peskov assisted his cosmonaut crewmates with the cargo work, worked on computer electronics gear, and photographed the external condition of Poisk with the Progress 92 docked to it.

NASA’s Hubble and Webb Telescopes Reveal Two Faces of a Star Cluster Duo

Bluish clouds of gas are wound through with red-glowing lanes and filaments of dust.. The clouds contain cavities filled with stars and many more stars are visible in the background and scattered throughout the clouds. The clouds are concentrated in the upper right and the lower middle of the image. Tiny background galaxies are also sprinkled throughout the image.
A vast network of stars, gas, and dust is strung among a duo of star clusters in this combined image from NASA’s Hubble and Webb space telescopes. Open clusters NGC 460 and NGC 456 reside in the Small Magellanic Cloud, a dwarf galaxy orbiting the Milky Way. This highly detailed 527 megapixel mosaic consists of 12 overlapping observations and includes both visible and infrared wavelengths.

A riotous expanse of gas, dust, and stars stake out the dazzling territory of a duo of star clusters in this combined image from NASA’s Hubble and Webb space telescopes.

Open clusters NGC 460 and NGC 456 reside in the Small Magellanic Cloud, a dwarf galaxy orbiting the Milky Way. Open clusters consist of anywhere from a few dozen to a few thousand young stars loosely bound together by gravity. These particular clusters are part of an extensive complex of star clusters and nebulae that are likely linked to one another. As clouds of gas collapse, stars are born. These young, hot stars expel intense stellar winds that shape the nebulae around them, carving out the clouds and triggering other collapses, which in turn give rise to more stars.

In these images, Hubble’s view captures the glowing, ionized gas as stellar radiation blows “bubbles” in the clouds of gas and dust (blue), while Webb’s infrared vision highlights the clumps and delicate filamentary structures of dust (red). In Hubble images, dust is often seen silhouetted against and blocking light, but in Webb’s view, the dust – warmed by starlight – shines with its own infrared glow. This mixture of gas and dust between the universe’s stars is known as the interstellar medium.

Slide to switch between Hubble and Web images. Hubble’s view captures visible light and some infrared wavelengths, while Webb’s view is exclusively infrared. The nebulae’s glowing gas, ionized by the radiation of nearby stars, is distinct in Hubble’s view. Dusty areas that appear dark in the Hubble image are visible as bright structures in the Webb image, and more background galaxies are visible since infrared light from fainter and farther galaxies can pass through the obscuring clouds of gas and dust.

The nodules visible in these images are scenes of active star formation, with stars ranging from just one to 10 million years old. In contrast, our Sun is 4.5 billion years old. The region that holds these clusters, known as the N83-84-85 complex, is home to multiple, rare O-type stars, hot and extremely massive stars that burn hydrogen like our Sun. Astronomers estimate there are only around 20,000 O-type stars among the approximately 400 billion stars in the Milky Way.

The Small Magellanic Cloud is of great interest to researchers because it is less enriched in metals than the Milky Way. Astronomers call all elements heavier than hydrogen and helium – that is, with more than two protons in the atom’s nucleus – “metals.”  This state mimics conditions in the early universe, so the Small Magellanic Cloud provides a relatively nearby laboratory to explore theories about star formation and the interstellar medium at early stages of cosmic history. With these observations of NGC 460 and NGC 456, researchers intend to study how gas flows in the region converge or divide; refine the collision history between the Small Magellanic Cloud and its fellow dwarf galaxy, the Large Magellanic Cloud; examine how bursts of star formation occur in such gravitational interactions between galaxies; and better understand the interstellar medium.
