Mars 2020 Perseverance Joins NASA’s Here to Observe Program
Katie Stack Morgan and Nicole Spanovich with the NASA Here to Observe Program students and faculty from Kutztown University. Kutztown University The Mars 2020 Perseverance mission has recently joined the NASA Here to Observe (H2O) program, where NASA planetary missions are partnered with universities to encourage undergraduate students from historically marginalized groups to pursue a career in STEM. As part of this program, the Perseverance mission has been paired with Kutztown University, located in Kutztown, Pennsylvania. Selected undergraduate students at the university will be able to observe and interact with Perseverance mission team members throughout this academic year to learn about the individuals who are part of the team and what it means to work on the rover mission.
To help kick off the program and our new partnership, I traveled to Kutztown along with the Perseverance Deputy Project Scientist, Katie Stack Morgan. We met several members of the Kutztown faculty and staff, toured their beautiful campus, and spent time getting to know the students participating in the H2O program this year. Katie and I were impressed by the enthusiasm and engagement exhibited by the students during our visit. We presented an introduction to the Perseverance mission including the recent discoveries, upcoming plans, and who comprises the mission team. There was also ample time to answer the many thoughtful questions about both the mission and the career paths of both me and Katie.
As part of this program, the students will observe select Perseverance mission meetings and activities. We kicked this off in October when the students observed a Geologic Context Working Group meeting to learn how scientists work together to understand the data gathered by the rover and make decisions about what the rover should do next. The students will also be paired with mentors from the Perseverance mission team throughout this academic year where they’ll have the chance to learn about the various career paths our team members have taken, read scientific papers, and prepare for a trip to the Lunar and Planetary Sciences Conference.
Overall, we have a great plan for our H2O partnership and are looking forward to welcoming Kutztown University to the Perseverance mission!

X-ray: NASA/CXC/SAO/J. Drake et al, IR: NASA/JPL-Caltech/Spitzer; Image Processing: NASA/CXC/SAO/N. Wolk Most stars form in collections, called clusters or associations, that include very massive stars. These giant stars send out large amounts of high-energy radiation, which can disrupt relatively fragile disks of dust and gas that are in the process of coalescing to form new planets.
A team of astronomers used NASA’s Chandra X-ray Observatory, in combination with ultraviolet, optical, and infrared data, to show where some of the most treacherous places in a star cluster may be, where planets’ chances to form are diminished.
The target of the observations was Cygnus OB2, which is the nearest large cluster of stars to our Sun — at a distance of about 4,600 light-years. The cluster contains hundreds of massive stars as well as thousands of lower-mass stars. The team used long Chandra observations pointing at different regions of Cygnus OB2, and the resulting set of images were then stitched together into one large image.
The deep Chandra observations mapped out the diffuse X-ray glow in between the stars, and they also provided an inventory of the young stars in the cluster. This inventory was combined with others using optical and infrared data to create the best census of young stars in the cluster.
In this new composite image, the Chandra data (purple) shows the diffuse X-ray emission and young stars in Cygnus OB2, and infrared data from NASA’s now-retired Spitzer Space Telescope (red, green, blue, and cyan) reveals young stars and the cooler dust and gas throughout the region.
In these crowded stellar environments, copious amounts of high-energy radiation produced by stars and planets are present. Together, X-rays and intense ultraviolet light can have a devastating impact on planetary disks and systems in the process of forming.
Planet-forming disks around stars naturally fade away over time. Some of the disk falls onto the star and some is heated up by X-ray and ultraviolet radiation from the star and evaporates in a wind. The latter process, known as “photoevaporation,” usually takes between 5 and 10 million years with average-sized stars before the disk disappears. If massive stars, which produce the most X-ray and ultraviolet radiation, are nearby, this process can be accelerated.
The researchers using this data found clear evidence that planet-forming disks around stars indeed disappear much faster when they are close to massive stars producing a lot of high-energy radiation. The disks also disappear more quickly in regions where the stars are more closely packed together.
For regions of Cygnus OB2 with less high-energy radiation and lower numbers of stars, the fraction of young stars with disks is about 40%. For regions with more high-energy radiation and higher numbers of stars, the fraction is about 18%. The strongest effect — meaning the worst place to be for a would-be planetary system — is within about 1.6 light-years of the most massive stars in the cluster.
A separate study by the same team examined the properties of the diffuse X-ray emission in the cluster. They found that the higher-energy diffuse emission comes from areas where winds of gas blowing away from massive stars have collided with each other. This causes the gas to become hotter and produce X-rays. The less energetic emission probably comes from gas in the cluster colliding with gas surrounding the cluster.
Two separate papers describing the Chandra data of Cygnus OB2 are available. The paper about the planetary danger zones, led by Mario Giuseppe Guarcello (National Institute for Astrophysics in Palermo, Italy), appeared in the November 2023 issue of the Astrophysical Journal Supplement Series, and is available here. The paper about the diffuse emission, led by Juan Facundo Albacete-Colombo (University of Rio Negro in Argentina) was published in the same issue of Astrophysical Journal Supplement, and is available here.
NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the Chandra program. The Smithsonian Astrophysical Observatory’s Chandra X-ray Center controls science operations from Cambridge, Massachusetts, and flight operations from Burlington, Massachusetts.
JPL managed the Spitzer Space Telescope mission for NASA’s Science Mission Directorate in Washington until the mission was retired in January 2020. Science operations were conducted at the Spitzer Science Center at Caltech. Spacecraft operations were based at Lockheed Martin Space in Littleton, Colorado. Data are archived at the Infrared Science Archive operated by IPAC at Caltech. Caltech manages JPL for NASA.

Visual Description
This release features a composite image of the Cygnus OB2 star cluster, which resembles a night sky blanketed in orange, purple, and grey clouds.
The center of the square image is dominated by purple haze. This haze represents diffuse X-ray emissions, and young stars, detected by the Chandra X-ray observatory. Surrounding the purple haze is a mottled, streaky, brick orange cloud. Another cloud resembling a tendril of grey smoke stretches from our lower left to the center of the image. These clouds represent relatively cool dust and gas observed by the Spitzer Space Telescope.
Although the interwoven clouds cover most of the image, the thousands of stars within the cluster shine through. The lower-mass stars present as tiny specks of light. The massive stars gleam, some with long refraction spikes.

Europa Trek: NASA Offers a New Guided Tour of Jupiter’s Ocean Moon
NASA’s Europa Clipper mission is on its way to explore a moon of Jupiter that researchers believe may be one of the best places in the Solar System to search for life beyond Earth. While the spacecraft makes its more-than-five year journey to Europa, scientists, students, teachers, and the public can tour and explore the landforms of Europa with newly-released enhancements to NASA’s Europa Trek web portal.
One of the largest of Jupiter’s nearly 100 recognized moons, Europa is covered with a global ice cap. But beneath that crust of ice, researchers have found an ocean of liquid water, estimated to have about twice the volume of all of Earth’s oceans combined. This vast amount of liquid water is of particular interest to astrobiologists, scientists studying the origin, evolution, and distribution of life in the Universe. Though Europa’s ocean remains hidden beneath its global crust of ice, we can get important clues about its nature by studying the remarkable landforms of Europa’s icy surface.
To accompany the launch of Europa Clipper, NASA’s Solar System Treks Project released exciting new enhancements to its online Europa Trek portal on September 30, 2024. The new additions to Europa Trek allow users to interactively fly over and explore high-resolution imagery of Europa’s surface from the Voyager, Galileo, and Juno missions. Users can also take a new guided tour of Europa’s amazing landforms, with commentary developed by a collaboration between NASA’s Astrobiology Science Communication Guild and NASA’s Solar System Exploration Research Virtual Institute. The tour and its commentary introduce virtual explorers to the geology and possible biological significance of the diverse features of Europa’s surface.
“This is really fun. It’s cool how you can zoom into the high resolution data. I’ll spread the word about using this!” – Bob Pappalardo, Europa Clipper Project Scientist
The new tour and capabilities of Europa Trek were featured at the Europa Clipper public launch program at the Kennedy Space Center Visitor Center on October 6,2024, in advance of the October 14 launch of the mission. As part of the public program conducted by NASA’s Planetary Mission Program Office, the Europa Trek exhibit allowed hundreds of visitors to try their hands at flying over Europa and visualizing its exotic terrain.
NASA’s Solar System Treks is an infrastructure project within NASA’s Science Activation Team. Their online portals are used for mission planning, planetary science research, and Science, Technology, Engineering, & Mathematics (STEM) education. NASA’s Astrobiology Science Communication Guild is an international, community-based network of astrobiologists who engage in science communication with diverse audiences and learners. Watch for future collaborations between Solar System Treks and the Astrobiology Science Communication Guild at more locations across the Solar System!
