NASA’s Aerospace Safety Advisory Panel Releases 2025 Annual Report 

Credit: NASA

The Aerospace Safety Advisory Panel (ASAP), which advises NASA and Congress on safety, has released its 2025 annual report on NASA’s performance and challenges.  

While the panel acknowledged NASA’s safety achievements, it warned that the agency’s biggest challenges stem from interconnected factors – workforce, acquisition, technical authority, budgets, and the growing complexity of human spaceflight – requiring sustained attention as missions become more ambitious.

“Independent assessments like this will make NASA better,” said NASA Administrator Jared Isaacman. “The panel’s report underscores areas where we must raise the bar, from how we structure oversight and manage integrated risk to how we declare and learn from anomalies. We are wholly committed to transparency. That’s how we protect crews, earn trust, and keep the Artemis lunar campaign and our transition to a commercial presence in low Earth orbit on a safe, sustainable path.” 

This year’s report focused on the following topics: 

  • strategic vision and governance 
  • Moon to Mars program 
  • future U.S. presence in low Earth orbit 
  • health and medical risks in human spaceflight 
  • NASA’s X-59 Low-Boom Flight Demonstrator 

The panel noted progress on Artemis II readiness and improved oversight through the Moon to Mars Program Office, as well as safe International Space Station operations, advances in astronaut health research, and the first flight of the X-59 Low-Boom Demonstrator. At the same time, it flagged significant challenges, including Artemis III’s high-risk posture, lessons from Boeing’s Starliner test, space station deorbit planning, and systemic concerns. 

To respond to these new challenges, the panel recommends NASA: 

  • Realign its governance of acquisition strategies for human spaceflight-related capabilities agencywide. 
  • Re-examine the mission objectives and system architecture for Artemis III and subsequent missions to establish a more balanced approach to risk.  
  • Require timely declaration of mishap or high-visibility close call. 

“We were already on the path to implementing change and this report only adds more urgency,” added Isaacman. “That means recalibrating our acquisition strategy — including a build versus buy versus service procurement approach — restoring core competencies through initiatives like converting contractors to civil servant roles and increasing our launch cadence. We’re also aligning our long-term vision for the agency and industry to guide priorities. This includes clarifying our plans for the Artemis architecture moving forward and accelerating proposals for human landing systems to preserve schedule margin. We’ve already shown what transparency and now accountability looks like — through the Boeing Starliner Program Investigation Team report, we owned our mistakes, classified the mission as a Type A mishap, and launched corrective actions to ensure they never happen again. These steps, along with addressing health and medical risk documentation and overhauling and accelerating programs like X-59, reflect our commitment to live up to the expectations of the world’s most accomplished space agency.”  

On Feb. 19, Isaacman held a news conference to present the agency’s findings from the Starliner Crewed Flight Test. Earlier this month, he outlined a new workforce plan to strengthen NASA’s core competencies in technical, engineering, and operational excellence. The agency also is working with both its human landing system industry providers to streamline and accelerate America’s return to the surface of the Moon by 2028. 

“The panel commends NASA for its impressive efforts in 2025 to strategically enhance the agency’s risk management posture despite turbulence in the agency’s organizational environment,” said retired U.S. Air Force Lt. Gen. Susan J. Helms, chair of ASAP. “We very sincerely thank NASA’s leaders and workforce for their passionate dedication to space exploration and their unwavering commitment to the safe pursuit of the nation’s lofty aims to the great benefit of the future of humanity.”  

The annual report is based on the panel’s 2025 fact-finding and quarterly public meetings; direct observations of NASA operations and decision-making; discussions with NASA management, employees, and contractors; and the panel members’ experiences.  

Congress established the panel in 1968 to provide advice and make recommendations to the NASA administrator on safety matters after the 1967 Apollo 1 fire claimed the lives of three American astronauts.

NASA’s Webb Examines Cranium Nebula

Side-by-side images of the same nebula show how differently it appears in near-infrared, on the left, versus mid-infrared light, on the right. Left image is labeled NIRCam and the right is labeled MIRI. In near-infrared, the nebula’s outer bubble has a white edge and its inner clouds are orange, with a distinct dark lane cutting vertically through the center. Stars and background galaxies appear around the nebula and through the outer bubble. In mid-infrared, the outer bubble has a bluish tint and there is more material in the inner clouds, which are colored off-white. The vertical dark lane is still present but more interrupted and covered by the clouds. Material appears to be erupting out the top of the nebula, and this effect is mirrored to a lesser degree at the bottom, opposite end.

Two heads are better than one in the latest images from NASA’s James Webb Space Telescope, which reveal new detail in a mysterious, little-studied nebula surrounding a dying star. 

Nebula PMR 1 is a cloud of gas and dust that bears an uncanny resemblance to a brain in a transparent skull, inspiring its nickname, the “Exposed Cranium” nebula. Webb captured its unusual features in both near- and mid-infrared light. The nebula was first revealed in infrared light by a predecessor to Webb, NASA’s now-retired Spitzer Space Telescope, more than a decade ago. Webb’s advanced instruments show detail that enhances the nebula’s brain-like appearance.

The nebula appears to have distinct regions that capture different phases of its evolution — an outer shell of gas that was blown off first and consists mostly of hydrogen, and an inner cloud with more structure that contains a mix of different gases. Both Webb’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) show a distinctive dark lane running vertically through the middle of the nebula that defines its brain-like look of left and right hemispheres. Webb’s resolution shows that this lane could be related to an outburst or outflow from the central star, which typically occurs as twin jets burst out in opposite directions. Evidence for this is particularly notable at the top of the nebula in Webb’s MIRI image, where it looks like the inner gas is being ejected outward. 

While there is still much to be understood about this nebula, it’s clear that it is being created by a star near the end of its fuel-burning “life.” In their end stages, stars expel their outer layers. It’s a dynamic and fairly fast process, in cosmic terms. Webb has captured a moment in this star’s decline. What ultimately happens will depend on the mass of the star, which is yet to be determined. If it’s massive enough, it will explode in a supernova. A less massive Sun-like star will continue to shed layers until only its core remains as a dense white dwarf, which will cool off over eons. 

The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

December 8, 2025

On December 6, 2025, a powerful magnitude 7.0 earthquake struck the remote St. Elias Mountains, a highly glaciated range that spans the Yukon-Alaska border. The quake shook the landscape beneath Hubbard Glacier, sending ice and rock careening down the range’s steep slopes. The NISAR (NASA-ISRO Synthetic Aperture Radar) satellite offered some of the earliest views of the changed landscape.

Geophysicist Eric Fielding and colleagues at NASA’s Jet Propulsion Laboratory (JPL) typically use satellite data to map the displacement of the ground after major earthquakes strike land. But in this region, such maps—known as interferograms—are not possible because the ground lies buried beneath a layer of glacial ice that’s at least 700 meters (2,000 feet) thick. “The cryosphere is covering up the geosphere,” Fielding said.

Instead, clues to the earthquake’s destructive power lay strewn atop the ice surface. The shaking on December 6 unleashed landslides and avalanches that swept debris onto lower, flatter stretches of the glacier. The debris is visible in radar imagery acquired by NISAR on December 8, two days after the quake (right). For comparison, the NISAR image on the left shows the same area on November 26, a week and a half before the quake.

Where the slides have deposited rock, snow, and other debris, surfaces have become rougher, which scatters more energy back toward the sensor and makes those areas appear bright in the December 8 image (the roughest areas are shown in dark green). Areas with smooth surfaces reflect little of the radar’s energy directly back to the satellite sensor, so these parts of the images appear dark (shown in purple). Note that there are some exceptionally rough, green surfaces beyond the new slide areas that remain relatively unchanged between the two images.

The largest slide in the scene appears to be cascading down the flank of Mount King George, but it’s far from the only one. Numerous others scar the surrounding terrain, including areas to the west along the slopes of Mount Logan, Canada’s tallest mountain.

Alex Gardner, a glaciologist at JPL and member of the NISAR science team, reviewed the images with Fielding. “The sheer number and magnitude of avalanches and landslides is astounding,” Gardner said. “I’ve personally never seen anything like this before.”

A separate preliminary analysis by the U.S. Geological Survey identified more than 700 potential landslides and snow avalanches, with an especially high concentration northwest of the epicenter along the fault rupture. Follow-up flights by the Yukon Geological Survey on December 12 provided a closer look, showing some slopes remained actively unstable, with dust still hanging in the air, and widespread damage to glacial ice.

Much of the debris that settled atop the region’s glacial ice is likely being transported toward the ocean by the glaciers’ ongoing seaward flow, which acts as a natural “conveyor belt.” For example, a tributary glacier of Hubbard north of Mount King George, which had previously moved at a sluggish pace, entered a surging phase in November before the earthquake. It is now moving downslope at what Gardner described as “breakneck speeds” of up to 6,000 meters per year (about 50 feet per day).

Although the region is uninhabited, the slides and damaged ice could pose new hazards for mountaineers and other expeditions, USGS noted in a December 18 update. The town of Yakutat, Alaska, about 90 kilometers (56 miles) south of the epicenter, is a common staging point for people exploring the area.

NISAR observations are expected to provide imagery to support future natural disaster response efforts.

Curiosity Blog, Sols 4812-4819: Back Into the Hollows

A grayscale landscape photo from the Martian surface shows a dark gray band of sandy terrain in the foreground, filling the bottom quarter of the frame, topped by a jagged, rocky ridge along its right half. Beyond that is a more distant area in very light gray, creating a horizon line from the lower third of the left side of the image, upward toward the center-right edge. This area and the sky above is very hazy, as if clouded by a dust storm.
NASA’s Mars rover Curiosity acquired this Navcam image looking out towards the northern rim of Gale Crater. Compared to just a few months ago, the view is much hazier, reflecting the higher amount of atmospheric dust that is typical of this time of year. Curiosity captured the image using its Left Navigation Camera on Feb.19 — Sol 4813, or Martian day 4,813 of the Mars Science Laboratory mission — at 12:15:50 UTC.

Earth planning date: Friday, Feb. 20, 2026

This has been a pretty routine week for Curiosity. As was mentioned last week, we’re now in the final phase of the boxwork exploration campaign. We’re currently making our way toward the eastern contact of the boxwork formation with the surrounding geology, which we plan to drive along before turning our attention to the southern contact. That will likely be our last opportunity to directly interrogate the boxwork area before we continue our adventure up the slopes of Mount Sharp.

Along the way, we’ve been performing our usual investigations of the geology that we encounter at our parking locations. As always, this includes contact science on bedrock targets close to the rover, ChemCam LIBS observations of targets slightly further afield, and a number of ChemCam RMI and Mastcam mosaics. These mosaics include observations deeper into the “Tapiche” hollow where we’re parked and the “Los Flamencos” ridge to its south, which we plan on investigating closer in the coming week.

Mars continues to move deeper into its dusty season, so the environmental science group filled this week’s plan with a typical assortment of atmospheric monitoring activities to track dust devils and the amount of dust in the atmosphere, as well as several Navcam cloud movies. So far this dusty season the atmosphere over Gale Crater appears to be behaving much like it does most years, with no signs of imminent dust storms. It’s now been almost eight years (four Mars years) since the last time that a global dust storm swept across the planet, so we’re keeping a close eye on the possibility of another one occurring this year.
