Next, Sierra Space must complete final integration and secure a firm launch slot on a Vulcan or Atlas V. - NASA Posts Moon Photography Guide for Public Use — NASA
NASA released an online guide explaining how to capture clear images of the Moon with consumer cameras. The guide covers exposure settings, lens choices, and timing around lunar phases. It encourages amateur photographers to share their results with the agency. The resource draws on imagery from lunar orbiters to show what features are visible from Earth. Users can now apply the same techniques during upcoming full Moons. - Artemis III Crew Training Details Released in Podcast — NASA
The latest Houston We Have a Podcast episode features Artemis III Chief Training Officer Debbie O’Connell. She describes how the crew will rehearse every phase from launch through splashdown. Training includes simulations of lunar surface operations and emergency procedures. O’Connell calls the four-person crew an all-star team. The episode provides the most detailed public look yet at the mission’s training timeline. - JAXA Links VTuber Character to Mercury Orbiter — COVERedge
A JAXA researcher explained how the hololive VTuber “Mio” became associated with the Mercury Magnetospheric Orbiter. The connection began as an informal outreach project and grew into public engagement material. The orbiter studies Mercury’s magnetic field and particle environment. The collaboration shows how space agencies are using popular culture to reach new audiences. JAXA plans similar partnerships for future missions. - Peatland Fires Create Widespread Smoke in Indonesia — NASA Science
NASA’s Aqua satellite captured images of smoke from smoldering peatland fires across Indonesia. The fires burn both on the surface and underground during the current drought. Peat fires release large amounts of carbon and create persistent haze. The imagery helps track the fires’ extent and intensity. Officials are using the data to assess air-quality impacts on nearby communities. - Worcester Students Scheduled for ISS Radio Contact — This Week in Worcester
Students at the EcoTarium in Worcester will speak directly with astronauts aboard the International Space Station later this month. The contact uses amateur radio equipment installed at the science museum. Participants have prepared questions about daily life in orbit and station experiments. The event is part of the ARISS program that connects schools and museums worldwide. It will be the first such contact for the museum. - Lobster Claw Nebula Captured in New Image — Astronomy Magazine
An Italian astrophotographer recorded the faint emission nebula Sharpless 2-157 in Cassiopeia and Cepheus. The nebula’s shape is sculpted by winds from the massive stars of the Cassiopeia OB2 association, including the Wolf-Rayet star WR 157. Long exposures reveal delicate filaments of ionized gas. The image highlights how stellar feedback shapes interstellar material. Similar structures appear in other star-forming regions. - HASP Balloon Completes 20th Student Flight Campaign — NASA Science
NASA launched the High-Altitude Student Platform from Fort Sumner, New Mexico, on September 2. The balloon carried student-built payloads to roughly 122,000 feet for six hours and forty-five minutes. This marks the twentieth flight of the HASP program, which gives university teams access to near-space conditions. Instruments on board tested new sensors and materials. Data from the flight will support future student experiments. - Dragonfly Rotorcraft Receives Final Wiring at APL — NASA Science
Technicians at Johns Hopkins Applied Physics Laboratory are installing dozens of silver cable bundles inside NASA’s Dragonfly spacecraft. The wiring connects the vehicle’s eight rotors, science instruments, and power systems. Dragonfly is scheduled to land in a region on Titan now officially named by the mission team. The clean-room work confirms the spacecraft is moving from structural assembly to systems integration. Launch remains planned for the late 2020s. - NASA Updates Community College Aerospace Program — NASA Science
The agency refreshed the NASA Community College Aerospace Scholars challenge for the coming year. Students will complete online modules, interact with NASA experts, and explore career pathways in aerospace. The program targets community college participants across the United States. Updated content includes new mission examples and virtual facility tours. Applications are now open for the next cohort. - Mercury’s Crust Linked to Extreme Early Volcanism — Universe Today
Researchers used lunar sample data to model how silicon dioxide abundance reveals volcanic styles on ancient Mercury. High SiO2 levels point to rapid, high-temperature eruptions that built much of the planet’s crust. The approach allows scientists to compare volcanic histories across terrestrial worlds without new samples from Mercury. The study refines understanding of how small planets differentiate. Follow-up papers will apply the same method to other bodies. - Sounding Rocket Flies Through Sporadic E Layer — Phys.org Space
A NASA sounding rocket carried five detectors through a metallic haze layer created by vaporized meteor dust. The simultaneous measurements revealed unexpected fine-scale structure inside the layer. Sporadic E clouds can disrupt radio signals and GPS. The flight provided the first multi-point view of how these layers form and dissipate. Scientists will use the data set to improve ionospheric forecast models. - Young Sunlike Star Shows Signs of Exocomets — Phys.org Space
Astronomers at Lund University detected evidence of comets orbiting a young star similar to the Sun. The observations suggest these bodies could deliver water to the inner regions where planets are forming. The star’s age places it in a phase when planetary systems are still assembling. Spectral signatures indicate volatile material is being transported inward. Continued monitoring will track how often such events occur. - Hubble Spots New Ten-Sided Wave at Saturn’s South Pole — Phys.org Space
Recent Hubble images show a giant, evolving, ten-sided atmospheric wave circling Saturn’s south pole. The feature resembles the well-known northern hexagon but appears in the southern hemisphere for the first time. Scientists believe they are watching a new jet-stream pattern develop. The wave’s regular shape offers a fresh laboratory for studying giant-planet atmospheric dynamics. Additional observations are planned during upcoming oppositions. - Cluster Spacecraft Reentry Yields Reentry Data Set — Phys.org Space
The final Cluster satellite, Tango, reentered on September 1 after targeted maneuvers. Scientists aboard an aircraft recorded the breakup in detail, creating a unique data set on satellite demise. The campaign tested safe end-of-life disposal techniques for future missions. Data will inform designs that reduce debris and improve atmospheric reentry predictions. Four targeted reentries across the Cluster fleet provided repeated observation opportunities.
Cosmic Spotlight
The HASP balloon campaign’s twentieth flight demonstrates how student-built instruments can reach the edge of space on a regular cadence. Payloads tested new sensors under near-vacuum conditions that ground labs cannot fully replicate. The six-hour-and-forty-five-minute float at 122,000 feet gave teams real flight heritage data they can cite in future proposals. This steady access helps bridge the gap between university projects and professional missions. What experiment would you design if you had a seat on the next HASP flight?
Cosmic Deep Dive: How Meteoric Dust Builds Temporary Radio Shields
Picture a single meteor the size of a grain of rice streaking through the upper atmosphere at 70 kilometers per second; in the span of a heartbeat it vaporizes and releases a few grams of metal atoms that spread into a thin horizontal sheet roughly the area of a large city. Those atoms collide with air molecules, lose electrons, and form a patchy layer of ions and electrons between 90 and 120 kilometers up—exactly where shortwave radio and GPS signals pass. The layer can appear in minutes and vanish in hours, yet while it lasts it can reflect or absorb radio waves the way a temporary mirror blocks a flashlight beam. One surprising number keeps appearing in the measurements: the electron density inside these sporadic E clouds can reach 100,000 electrons per cubic centimeter, high enough to bend signals that would normally travel straight through. We can map the patches with rockets and radar, but nobody yet knows why the metal atoms sometimes clump into neat, long-lived sheets instead of simply diffusing away.
Space keeps delivering fresh data and fresh questions every single day.
