A School of Mud Volcano Islands in Azerbaijan

Today’s story is the answer to the April 2026 puzzler.  

With its abundance of naturally occurring gas seeps and fires, Azerbaijan has long been called “the land of fire.” Yet burning mountains are just one of the geologic wonders found in the small Eurasian country on the Caspian Sea.

Azerbaijan is also home to at least 220 mud volcanoes, according to data from the Azerbaijani government, though some researchers put the total number closer to 350. That is thought to be one of the highest concentrations of mud volcanoes on Earth.

Mud volcanoes—as well as gas seeps—are found within sedimentary basins where geologic conditions have allowed hydrocarbons to accumulate. Such basins typically have fluids and gases, such as oil and methane, trapped beneath sedimentary rocks and under high pressure. Instead of erupting molten lava, mud volcanoes typically eject cold slurries of mud, water, methane, and other gases. Oil and gas form from the remains of marine organisms, such as phytoplankton and algae, which settle on the ocean floor and are later transformed by pressure and heat.

Many of Azerbaijan’s mud volcanoes are clustered near the cities of Baku and Qobustan on the Absheron Peninsula, an area where structural folds and faults in the landscape have created cracks that allow methane-rich mud to move up toward the surface. On land, mud volcanoes typically form conical structures anywhere from 20 to 400 meters (70 to 1,300 feet) tall and 100 to 4,500 meters in diameter.

There are also at least 140 underwater mud volcanoes in the South Caspian Sea along Azerbaijan’s coast, including eight islands in the Baku archipelago. The satellite image above shows one of them, the tadpole-shaped Xərə Zirə Adası (also known in Russian as Ostrov Bulla), which had violent eruptions in 1961 and 1995 and still has two “weakly active” mud volcano vents, said Adelaide University geologist Mark Tingay. The neighboring island to the northwest, Duvannı (Ostrov Duvannyy), is visible in the wide view below. It erupted in 2006 and still has active vents on its northern side.

“The islands’ ‘tails’ are most likely caused by currents eroding their weak mud deposits,” Tingay said. “They look like spits of eroded and redeposited sediment that formed on the lee of the island, where current and wave action have the least effect.”

There are two more tadpole-shaped islands to the south, with sediment “tails” also oriented to the southwest. One of these—Səngi Muğan Adası (Ostrov Svinoy)—is known for producing particularly violent eruptions, most recently in 2002 and 2008, Tingay said. One of its most notorious events occurred in 1932 when, without warning, it released a 150-meter-tall fireball in an eruption that caused 13 injuries and almost destroyed the island’s lighthouse, he added. 

Though mud volcanoes are interesting to geologists and often indicators of underground fossil fuels, they can be unpredictable and pose risks. “They have the potential for ‘paroxysmal eruptions’—short but extremely violent eruptions,” Tingay said. “They sometimes fuel huge fireballs and have created whole new islands in the space of a few minutes.”

NASA on Track for Future Missions with Initial Artemis II Assessments

2026-04-20 22:10

Following NASA’s Artemis II mission successfully splashing down on Earth, engineers started diving into detailed analysis of data to assess how key systems and subsystems on the Orion spacecraft, SLS (Space Launch System) rocket, and systems at the launch pad at the agency’s Kennedy Space Center in Florida performed. The Artemis II test flight successfully began a new era of exploration, laying the groundwork for the third Artemis mission next year, lunar surface missions, a Moon base, and future missions to Mars.

Orion spacecraft

After its 694,481-mile journey around the Moon and back, the agency’s Orion spacecraft successfully reentered Earth’s atmosphere and splashed down off the coast of San Diego on April 10. The crew and spacecraft were safeguarded by Orion’s thermal protection system as they traveled nearly 35 times the speed of sound during reentry. Initial inspections of the system found it performed as expected, with no unusual conditions identified. Diver imagery of the spacecraft’s heat shield initially taken after splashdown and further inspections on the recovery ship found the char loss behavior observed on Artemis I was significantly reduced, both in terms of quantity and size. Performance also was consistent with arc jet facility ground testing performed after Artemis I.

Airborne imagery of Orion’s crew module also was obtained during re-entry and will be reviewed in the coming weeks. This imagery will provide insight into the timing of when minimal char loss occurred as well as other heat shield data.

Murtha, on Saturday, April 11, 2026, in the Pacific Ocean off the coast of California.

The crew module is expected to return to NASA Kennedy this month for additional examination of the heat shield during Orion de-servicing in the Multi-Payload Processing Facility. Teams will conduct detailed inspections, retrieve post-flight data, remove reusable components such as avionics, and eliminate remaining hazards such as excess fuel and coolant.

Over the summer, the heat shield will be transported to NASA’s Marshall Space Flight Center in Huntsville, Alabama, for sample extraction and internal x-ray scans to provide further insight into the system and material behavior.

The ceramic tiles on the upper conical backshell of the crew module also performed as expected. Reflective thermal tape, which is expected to burn off upon re-entry, is still present in numerous locations. This reflective tape is used to help control vehicle temperatures while in space and serves no function for thermal protection upon re-entry.


Orion splashed down with precision, just 2.9 miles from the targeted landing site. Initial assessments showed entry interface velocity was within one mile-per-hour of predictions.

After splashdown, several Orion components were removed in San Diego for post flight analysis and future reuse prior to the spacecraft’s return to Kennedy. These items included seats, video processing units, crew module camera controllers, stowage containers and bags, and Orion Crew Survival System suit umbilicals.


The team currently is assessing the hardware and gathering data to support the post flight investigation of the urine vent line issue during the Artemis II mission. Teams will work to identify root cause and initiate corrective action for Artemis III.

America’s Moon rocket

The SLS rocket that launched the Artemis II mission also performed well, meeting its mission objectives for the test flight. While engineers continue studying the data, an early assessment indicates the rocket accurately placed Orion where it needed to be in space. At main engine cutoff, when the core stage’s RS-25 liquid engines shutdown, the spacecraft was traveling at over 18,000 miles per hour, achieving its insertion velocity for orbit, and executing a precise bullseye for its intended location.

Exploration Ground Systems

Engineers conducted a detailed post-launch pad and mobile launcher assessment, following the launch of the Artemis II crew and rocket. Application of lessons learned from Artemis I to harden and reinforce ground support equipment at the pad proved successful as the mobile launcher and launch pad sustained minimal damage in the wake of the powerful booster ignition. 

In addition to performing washdowns of the mobile launcher and pad ground systems immediately following launch, some components were made more rigid, like elevator doors, while others were made more compliant, such as gaseous distribution panels in the base of the mobile launcher, modified to flex with the blast effects. Other components were protected with blast-resistant walls or covers. These allowed the pneumatics system, which involves air and gas, to remain operational postlaunch and the critical cooling and washdown water flows to proceed.

Teams returned NASA’s mobile launcher that supported the integration and launch of the Artemis II rocket to NASA Kennedy’s Vehicle Assembly Building to undergo repairs and prepare for support of future Artemis missions.

The agency’s recovery teams, alongside their military partners, successfully conducted recovery operations after the safe splashdown of the crew inside their spacecraft. Navy divers retrieved each crew member and brought them aboard USS John P. Murtha before helping to recover the Orion spacecraft and return to Naval Base San Diego.

Using data from the first crewed mission under the Artemis program, NASA continues preparing the hardware and teams to launch and fly the Artemis III mission in 2027 ahead of subsequent missions to the Moon’s surface beginning in 2028.

NASA Rolls Out Artemis III Moon Rocket Core Stage

2026-04-20 20:31

Following the recent successful test flight of NASA’s Artemis II mission around the Moon, NASA rolled out the core stage, or the largest section, of the agency’s SLS (Space Launch System) rocket that will launch the crewed Artemis III mission in 2027. The stage departed from the agency’s Michoud Assembly Facility in New Orleans on Monday for shipment to NASA’s Kennedy Space Center in Florida, marking key progress on the path to the agency’s first crewed lunar landing mission to the Moon under the Artemis program in two years.

Using highly specialized transporters, engineers maneuvered the top four-fifths of the SLS core stage, the section containing the liquid hydrogen tank, liquid oxygen tank, intertank, and forward skirt, from inside NASA Michoud to the agency’s Pegasus barge for delivery to NASA Kennedy. After arrival, teams will complete the stage outfitting and vertical integration, and the agency’s Exploration Ground Systems Program will stack the rocket’s components in preparation for launch.

“Seeing this SLS rocket hardware roll out is a powerful reminder of our progress toward returning humans to the lunar surface,” said Lori Glaze, acting associate administrator, Exploration Systems Development Mission Directorate at NASA Headquarters in Washington. “This is the backbone of Artemis III. As it heads to Florida for final integration, we are one step closer to testing the critical capabilities needed to land Americans on the Moon, and ultimately, paving the way for our first crewed missions to Mars.”

At 212 feet tall, the completed core stage will consist of the top four fifths of the rocket combined with its engine section. The top four-fifths include the two propellant tanks that collectively hold more than 733,000 gallons of super-chilled liquid propellant to fuel four RS-25 engines. During launch and flight, the fully integrated stage will operate for more than eight minutes, producing more than 2 million pounds of thrust to propel astronauts inside NASA’s Orion spacecraft into orbit.

Building, assembling, and transporting the core stage is a collaborative process for two of NASA’s prime contractors, Boeing and L3Harris Technologies. Boeing is responsible for the overall design and assembly of the core stage, and L3Harris manufactures the rocket’s RS-25 engines. Recent announcements by NASA Administrator Jared Isaacman enabled the agency to standardize the SLS configuration, streamline operations, and optimize production to accelerate the Artemis program.

Next year’s Artemis III mission will launch astronauts to Earth’s orbit aboard the Orion spacecraft on top of SLS to test rendezvous and docking capabilities between Orion and commercial spacecraft needed to land Artemis IV astronauts on the Moon in 2028. NASA’s SLS is the only rocket capable of sending Orion, astronauts, and supplies to the Moon in a single launch.

As part of the Golden Age of innovation and exploration, NASA will send Artemis astronauts on increasingly difficult missions to explore more of the Moon for scientific discovery, economic benefits, establish an enduring human presence on the lunar surface, and to build on our foundation for the first crewed missions to Mars.
