WASP-189b shows matching chemistry with its host star — SSBCrack Astronomers captured the transmission spectrum of the hot Jupiter WASP-189b as it passed in front of its host star. The data revealed that the planet’s atmosphere contains elemental abundances that closely mirror those measured in the star itself. This direct chemical link suggests the planet and star drew from the same reservoir of material during formation. The observations were made with high-resolution spectroscopy that isolates the planet’s atmospheric signal from the star’s light. Such matches help refine models of how giant planets accrete gas and solids in the disks around young stars. The result opens a path to compare chemistry across more hot Jupiters and their hosts in coming years. Source: news.ssbcrack.com

Project Atlas announced at University of North Dakota — The Flag - AM 1100 and FM 92.3 WZFG Senator John Hoeven introduced Project Atlas during an event at the University of North Dakota. The initiative aims to strengthen the state’s contributions to space research and national security programs. NASA Administrator Jared Isaacman and leaders from the Golden Dome initiative attended to underscore federal interest. The project will support new research facilities and training programs that prepare students for roles in aerospace and defense. UND will serve as the hub for partnerships that connect academic work with ongoing federal space priorities. Officials expect the effort to create pathways for North Dakota graduates into NASA and industry missions. Source: am1100theflag.com

Christina Koch named acting deputy chief engineer at NASA — NASA Breaking Astronaut Christina Koch will begin serving as NASA’s acting deputy chief engineer on November 1. She follows Katherine Van Hooser, who retires on October 21 after more than 35 years at the agency. Koch previously completed 328 consecutive days aboard the International Space Station and flew as a mission specialist on the Artemis II crewed flight around the Moon. In her new position she will oversee technical reviews and mission readiness across NASA programs while moving to management astronaut status. NASA Administrator Jared Isaacman noted that Koch has experienced engineering challenges from both the development side and during actual spaceflight. Van Hooser’s career included leading propulsion engineering on the space shuttle main engine and serving as the first chief engineer for the Space Launch System liquid engines element. The transition keeps continuity in technical leadership as NASA advances lunar and Mars objectives. Source: nasa.gov

Perseverance sets new single-sol drive mark on Mars — NASA Breaking NASA’s Perseverance rover drove 299.6 feet, equivalent to 91.31 meters, during sol 2006 of its mission. The drive took the rover across the rocky floor of Jezero crater and produced fresh wheel tracks visible in navigation camera images. This single-sol distance contributed to the mission surpassing its previous cumulative distance record. The navigation cameras recorded the terrain ahead and behind the rover, giving engineers data on wheel slippage and rock interactions. Mission planners will use the new images to chart the next series of traverses while the vehicle continues its exploration of the ancient river delta. The record-setting push keeps the rover on schedule for additional science stops inside the crater. Source: science.nasa.gov

Griffin-1 lander finishes environmental tests at JPL — NASA Jet Propulsion Laboratory (JPL) Voyager Technologies completed nearly three months of environmental testing on its Griffin-1 lunar lander at NASA’s Jet Propulsion Laboratory in late September. The test campaign exposed the spacecraft to launch vibrations, thermal extremes, and simulated landing loads. Final verification confirmed that all systems can withstand the full sequence from liftoff through touchdown on the lunar surface. The lander carries Astrolab’s FLIP rover and several additional payloads destined for the Moon’s south polar region. With testing complete, the spacecraft moves into final integration and launch preparations. The mission will demonstrate precision landing near Mons Mouton close to the rim of Nobile crater.

Nature study identifies two families of multi-planet systems — Nature A large survey of confirmed exoplanet systems revealed two distinct architectural families. One group features tightly packed inner planets orbiting stars with higher metallicity and greater mass. The second group shows wider orbital spacing around lower-mass host stars. Researchers compiled the sample from transit and radial-velocity detections gathered by multiple ground- and space-based telescopes. The division indicates that the initial conditions of the protoplanetary disk, including its mass and composition, influence the final arrangement of planets. The study did not require new observations but instead re-analyzed existing catalogs to uncover the pattern. Future work will test whether disk turbulence or other variables determine which family a system develops. Source: nature.com

Perseverance’s 91.31-meter drive on sol 2006 left clear tracks across the boulder-strewn surface of Jezero crater. Navigation camera frames show the wheels carving fresh paths through loose regolith and small rocks, supplying engineers with real-time performance data. Each additional meter improves the odds that the rover will reach new sampling sites before its systems begin to degrade. The team is already reviewing the latest imagery to select the next waypoints while the vehicle remains in good health.

Cosmic Deep Dive: How Multi-Planet Architectures Trace Star Formation

If you stretched the orbital distances in some multi-planet systems down to everyday scale, the outermost world would sit roughly as far from the innermost as Toronto is from Vancouver. That vast span all formed inside a single rotating disk of gas and dust that once surrounded the newborn star. Picture yourself riding a parcel of that collapsing cloud as gravity flattens it into a thin pancake; closer to the center the temperature climbs so high that only rock and metal can condense, while farther out ices survive and stick together, locking in the raw materials for each future planet. The Nature study found one family of systems where planets hug their stars in tight orbits around higher-metallicity, higher-mass hosts, while the second family spreads out more widely around lower-mass stars. The split emerged after researchers examined thousands of planets already detected by transit and radial-velocity methods, without needing any new telescope time. A single surprising number stands out: the boundary between the two families appears tied to the host star’s mass and the amount of heavy elements it contains, suggesting the disk’s starting conditions set the final layout before the first planets even finish forming. We can map the two families across hundreds of systems, yet no one has identified the exact trigger that decides whether a disk produces the packed inner group or the spread-out version when the stars themselves look nearly identical. The lingering question is whether an early burst of turbulence or a slight difference in the disk’s initial magnetic field strength tips the outcome one way or the other.

A fresh batch of mission updates and exoplanet findings keeps the week moving.
