NASA announced Wednesday a mission to explore the history and evolution of the universe, PRIMA (PRobe far-Infrared Mission for Astrophysics), is advancing to the next phase of development. This space telescope is the first in a new class of NASA astrophysics missions, called Probe Explorers, within the agency’s longstanding Explorers Program.

“The PRIMA mission is humanity’s next window into the deep universe. It will unveil the obscure across cosmic time to better understand the formation of planets, stars, black holes, and even how water on Earth came to be,” said Nicky Fox, associate administrator, Science Mission Directorate, NASA Headquarters in Washington.

NASA selected PRIMA to move into Phase B, the stage of development that advances the preliminary design and technology development for the mission. The mission is subject to a confirmation review, based on technical, programmatic, and cost performance, to determine its readiness to begin implementation in Phase C. If confirmed, PRIMA’s project cost is capped at $1.2 billion, not including launch and other non-project costs. The observatory will be targeted to launch in 2033, for a planned five-year mission.

With a 5.9-foot telescope, PRIMA will conduct deep, sensitive surveys of the universe in far-infrared light, helping bridge the gap between existing infrared observatories, such as NASA’s James Webb Space Telescope, and radio telescopes. By studying radiant energy that only emerges in the far-infrared, PRIMA will address a wide range of questions about the universe. This includes the origins of planets outside our solar system, how galaxies and their black holes have grown and evolved over cosmic history, and how dust and heavy elements have built up in the universe over time – all helping paint a better picture of why the universe looks the way it does today.

“A single mission alone can’t probe all the universe’s mysteries. But by extending the survey capabilities of our fleet into far-infrared wavelengths with PRIMA, we’re enabling an incredibly comprehensive look at the cosmos,” said Shawn Domagal-Goldman, director, Astrophysics Division, NASA Headquarters. “With our Webb and Roman space telescopes, we set a cadence of launching premiere-class missions in both halves of the decade. We’re going to keep that up and kick off the next decade with PRIMA, as part of a pipeline that will consistently have missions of this caliber ready to go.”

The National Academies of Sciences, Engineering, and Medicine’s 2020 Decadal Survey, Pathways to Discovery in Astronomy and Astrophysics for the 2020s, recommended NASA establish this new Probe Explorers mission class. NASA selected PRIMA for development after detailed evaluation of concept studies for Probe Explorer missions, based on their scientific merit in alignment with the Decadal Survey’s recommendations, feasibility of their development plans on cost and schedule, and use of technologies that could support the development of future large missions.

NASA’s Jet Propulsion Laboratory in Southern California will manage the PRIMA mission. Other partners include NASA’s Goddard Space Flight Center in Greenbelt, Maryland and NASA’s Marshall Space Flight Center in Huntsville, Alabama. The PRIMA mission also will have contributions from international partners: CNES (Centre National D’Etudes Spatiales), ASI (Agenzia Spaziale Italiana), DLR (Deutsches Zentrum für Luft- und Raumfahrt), CSA (Canadian Space Agency), KASI (Korea Astronomy and Space Science Institute), JAXA (Japan Aerospace Exploration Agency), and the UK Space Agency.

The Explorers Program is the oldest continuous NASA program designed to provide frequent, low-cost access to space using principal investigator-led space science investigations relevant to the Science Mission Directorate’s astrophysics and heliophysics programs. Since the Explorer 1 launch in 1958, which discovered Earth’s radiation belts, the Explorers Program has launched more than 100 missions, including the Uhuru and Cosmic Background Explorer missions that led to Nobel prizes for their investigators.

The Explorers Program is managed by NASA Goddard for the Science Mission Directorate, which conducts a wide variety of research and scientific exploration programs for Earth studies, space weather, the solar system, and the universe.

Agricultural emissions represent an important and understudied part of Earth’s land and atmosphere systems. The FarmFlux mission will deploy more than a dozen sensors to measure ozone, methane, ammonia, particulates, and other pollutants rising from agricultural lands and animal farms and the interaction with the Earth’s atmosphere. The mission is jointly led by NASA’s Goddard Space Flight Center in Greenbelt, Maryland; Colorado State University; and Boston University. 

The Colorado deployment is the first series of flights for the FarmFlux mission. Additional low-altitude research flights are scheduled over farmland in Amarillo, Texas, from late October to early November. For the March to July 2027 growing season, research flights with a NASA P-3 Orion aircraft are scheduled in the Midwest and California’s Central Valley with a focus on croplands.

NASA’s Hubble Telescope Reaches Milestone, Looks for Elusive Supernova

Several galaxies shine against black space, with a large cluster near center-left.
An image from NASA’s Hubble Space Telescope of galaxy cluster MACS J0417 is part of repeated observations to monitor for the reappearance of supernova Athena, which can help astronomers measure the expansion rate of the universe.

NASA’s Hubble Space Telescope captured this image of massive galaxy cluster MACS J0417 (left of center) on Sept. 19, 2026. This galaxy cluster acts as a gravitational lens, bending and magnifying light from objects far behind it. Supernova Athena, discovered by NASA’s James Webb Space Telescope in 2025, is predicted to reappear between now and early March 2027. Measuring the timing of Athena’s reappearances can help researchers map the mass of MACS J0417, which acts as a magnifying, foreground lens for distant objects, and refine our understanding of the expansion rate of the universe.

Hubble also completed its 200,000th orbit around Earth on Sept. 19, marking another new milestone for an observatory that continues to transform our understanding of the universe.

Arid shrublands in Western Australia were bursting with life in late austral winter 2026, when a profusion of wildflowers brought vivid colors to the rusty ochre landscape. After several wetter-than-normal months earlier in the year, dormant seeds in the soil awoke to produce carpets of blooms. Local experts think the display could be the best the area has seen in nearly two decades.

The images above, captured with the OLI (Operational Land Imager) on the NASA-USGS Landsat 8 satellite, compare the more verdant landscape of late August 2026 (right) with a similar time in 2025 (left), when it was drier. This area is located about 600 kilometers (370 miles) north of Perth in the Murchison region, one of Western Australia’s main areas for grazing sheep and cattle. The local vegetation includes grasses, saltbush, and the slow-growing evergreen mulga tree.

Every so often, a variety of wildflowers makes an appearance, too. In 2026, rainfall totals were above average in June and very much above average in August due to several cold fronts moving through the area, according to Australia’s Bureau of Meteorology. The rains helped rouse a diverse mix of flowers to bloom across the outback, including on a radio astronomy site managed by the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia’s national science agency. The flower show included some threatened species, which the observatory has helped monitor on its formerly pastoral land.

Though the spectacle underfoot might have momentarily stolen the show, Inyarrimanha Ilgari Bundara, the CSIRO Murchison Radio-astronomy Observatory, is primarily focused on what’s overhead and the exploration of deep space. At the Murchison site, CSIRO operates several antenna arrays that observe and catalog objects in the southern sky. The remote facility is situated within a “radio quiet” zone, where terrestrial communications and electronic devices are controlled to limit electromagnetic interference with the instruments.

Other telescopes in CSIRO’s purview in Australia have played crucial roles in NASA missions from the agency’s early years to today. The Murriyang radio telescope in Parkes, New South Wales, tracked Mariner 2—the first successful planetary science mission—in 1962 and was an important receiving station for the Apollo 11 mission to the Moon in 1969. CSIRO also manages and operates the Canberra Deep Space Communication Complex, one of three facilities in NASA’s global Deep Space Network that supports interplanetary spacecraft missions and collects radar and radio astronomy observations. Both supported the Artemis II mission in April 2026.

Curiosity Blog, Sols 5010-5015: Checking out the Bands

A grayscale image of the Martian surface taken by the Curiosity rover. The immediate foreground features a dense field of jagged, light-colored, thinly-layered rock fragments resting on a bed of darker sand or dust. The barren terrain gently slopes upward toward the horizon, where a cluster of dark, rugged hills and a larger, rounded mountain peak on the far right stand out against a smooth, featureless sky.
NASA’s Mars rover Curiosity acquired this image, showing the path ahead. The subtle banding can be picked out here in tonal differences. Curiosity captured the image using its Right Navigation Camera on Sept. 14, 2026 — Sol 5014, or Martian day 5,014 of the Mars Science Laboratory mission — at 02:05:20 UTC.

Earth planning date: Friday, Sept. 11, 2026

This week we had two planning days (Tuesday and Friday), as Monday was Labor Day in North America, where many of the Curiosity team are based. Labor Day (the first Monday in September) marks the end of summer holidays and thrills, and the return to more typical routines and back to school.

The MSL team has marked several important milestones within the past few weeks — marking our 14th “Landiversary” on Aug. 6 and surpassing the 1-kilometer elevation mark and our 5000th sol (Martian day) in early September. Our next big date is not until Nov. 26, the 15th anniversary of launch, and so it feels like Curiosity is also back to a more routine schedule at this point.

We are moving up the valley known informally as “Valle Grande.” In recent weeks, we climbed up over what we interpreted as an “erosional supersurface” (which marks a gap in the usual rock record) and are now traversing through a subtly banded area. Bands are 25-200 meters (about 80-650 feet) in diameter, with morphological changes, such as bands with more sand and less rocky outcrops (which often appear darker from a distance because there is more sand) and others where outcrops seem more continuous that allow us to mark out rough contacts between them.  

The terrain this week was characterized by sparse outcrops with a rough texture, often nodular, surrounded by lots of sand and coarse pebbly sand. On Tuesday APXS and MAHLI investigated brushed nodular bedrock at “Cerro Armazones” and “Monte Melimoyu.” ChemCam acquired LIBS on a knot of dark-toned nodules at “Tuta Huallpas” and the dark-toned float rock “Acllahuasi.”

On Friday, after a drive of about 60 meters (nearly 200 feet), we found ourselves with mostly sand close to the rover and just one small rough-textured outcrop close enough for contact science and LIBS. Fortunately, the block was extremely interesting, with abundant small flakes and chips incorporated and laminated areas that are a bit smoother. We will investigate the rougher textures with MAHLI (“Yungay” and “Chiu Chiu”), APXS (Chiu Chiu) and ChemCam LIBS (“Puya Raimondii”) and a smoother area with LIBS (“Liolaemus Tacnae”).

Across both plans, the ChemCam long-distance imager and camera teams were hard at work. In addition to near-field images, which focus on areas close to the rover, both Mastcam and ChemCam acquired several larger mosaics on the buttes on either side of us (“Mishe Mokwa” and “Cordillera”) and looking back to the small butte “La Linea.” Mastcam also took some mosaics documenting the “Chocolatal” scuff, which we analyzed last week, and a larger mosaic of the “Sullivan Field” sand field where Chocolatal is located. Sullivan Field contains sand ripples, mega ripples, and transverse aeolian ridges, and was named by the team in honor of the late Robert Sullivan, a world expert on Martian sands and cherished member of the Curiosity science team.

In parallel to all the geology activities, the environmental team planned their usual full schedule of monitoring activities, such as dust-devil movies, suprahorizon movies looking at the crater rim, and tau images, which look at dust in the atmosphere.

Navcam and Mastcam acquired images of the path ahead in our drive direction. The subtle bands can just about be picked out here, by looking at tonal differences. It will be very interesting to see how these look and vary from each other when we get close enough to each one.

Risks of Decompression Sickness and Venous Thromboembolism during Spaceflight and Patent Foramen Ovale Implications

The purpose of this working group was to assemble a panel of experts to review the most recent data related to extravehicular activity (EVA) prebreathe testing and decompression sickness (DCS) events, venous thromboembolism (VTE) in-flight occurrences, and patent foramen ovale (PFO) implication as they relate to NASA’s Artemis (lunar and beyond) missions. The recommendations from this working group are built upon and integrate the outcomes of the September 2024 Assessment of Patent Foramen Ovale (PFO) as Related to Decompression Sickness (DCS) in the Spaceflight Environment and During Ground Testing (NASA/SP-20240010473), the April 2026 NASA Risk of Venous Thromboembolism in Spaceflight Working Group (NASA/SP- 20260005258/REV1), and the updated DCS prevention standard reviewed by the DCS panel in NASA-STD-3001 Volume 2 Human Factors, Habitability, and Environmental Health (NASA-STD-3001 Vol 2 Rev F), with a specific focus on risk mitigation interventions such as PFO closure.

Recommendations

The following is a summary of the working group’s recommendations:

  1. Ground-based studies should no longer remove subjects from research solely due to the presence of LVGE. Protocols should balance subject safety with population representativeness, and subjects must be fully informed of their LVGE status and any associated risks.
  2. The consensus was that the presence of a PFO is not considered a major risk factor for VTE formation, nor for complications from an embolism traveling from an initial formation site in the left internal jugular or cerebrum at normoxic or proposed hypoxic space habitats. No changes to astronaut selection criteria regarding PFOs are recommended with respect to VTE.
  3. The consensus of the group is that there is no definitive link between bubble grades and the risk of DCS at altitude for prebreathe protocols involving partial gravity and ambulation.
  4. The panel concluded that while minimizing bubbles is desirable, the predictive value of bubble scores for DCS remains uncertain, especially for lunar surface operations.
  5. It was determined that a “small” PFO (Grade 1 or 2) does not pose a significant risk. There were mixed opinions on whether closing or screening out crew members with a “large” PFO (Grade 3 or above) significantly reduces the risk of a venous gas embolism (VGE) passing to the arterial side and causing a significant mission health event. The group did not recommend universal screening or exclusion of astronauts with large PFOs but emphasized the importance of risk mitigation through protocol design and ongoing data collection. If crews are assessed, they should be informed of their status and offered closure for a large PFO.
  6. The panel concluded that clear clinical guidance is required regarding medication use for all crewmembers prior to Extravehicular Activities (EVAs). Specifically, protocols must address the use of aspirin for Decompression Sickness (DCS) prevention and pain relief. Additionally, guidance is needed for the pre and post-EVA use of analgesics (acetaminophen, ibuprofen, naproxen, celecoxib), as these medications have the potential to mask DCS symptoms.
