A study published in April 2025 provides new insight into one of the mysterious historical climate change periods known as LALIA (the Late Antique Ice Age). This period is known to last from 536 to 660 AD. The trio of scientists, namely, Christopher Spencer, Ross Mitchell and Thomas Gernon, published in a journal describing the analysis of misplaced Greenland rocks found lodged in the cliffs of Iceland, offering direct evidence of iceberg activity connected to this period of an ice age.

Discovery of the LALIA

The study was published in the journal Geology. As per Phys.org, the earlier research has depicted that the Earth’s northern hemisphere had undergone a chilly spell beginning around 540 AD because of the eruption of huge volcanoes, which led to the rise in debris in the atmosphere, leading to the darkening of the skies. A few historians speculated that the sudden cold weather led the Goths to attack the Romans in Europe, as they moved toward the south, warmer regions led to the fall of the Roman Empire.

Understanding the Misplaced Rocks

The researchers studied some cliffs on the western coast when they noticed that the rocks actually looked out of place. They collected a few rocks to study in the lab. The team crushed the rocks in the lab to study their remnants under a microscope. They pulled the zircon crystals from the centre of these rocks.

In their lab, the team crushed the rocks and looked at their remnants under a microscope, allowing them to pull out zircon crystals from their centres. These crystals can be used as a time capsule. After studying their age and composition, the scientists could trace the original place of these rocks across Greenland. This predicts that these rocks were moved by someone more than 1500 years ago.

The scientists studied the rocks’ age placed at the LALIA, depicting that the rocks were moved after breaking the ice from the large glaciers of Greenland that formed as per the colder scenarios formed during that period.

Scope of the Study

The research stands as a major step forward in understanding the Earth’s climate in the past. These rocks have given clear proof of increased glacial activity at the time of LALIA, indicating the outcomes of modern and future climatic changes.

A Falcon 9 rocket soared into space from Cape Canaveral Space Force Station in Florida on April 21 at 8:48 p.m. EDT (0048 GMT, April 22), carrying multiple payloads on SpaceX’s latest rideshare mission, Bandwagon-3. Among the diverse cargo onboard was Phoenix 1, a European-built reentry capsule developed by the German company Atmos Space Cargo. History will be made here in European aerospace with this launch, as Phoenix 1 becomes the first capsule from Europe intending to return from space and splash down on Earth after just one orbit, barely 1,200 miles offshore of Brazil.

Phoenix 1 Debuts as Europe’s First Private Reentry Capsule on SpaceX Bandwagon-3 Flight

According to Atmos Space Cargo, this mission is the first-ever atmospheric reentry attempt of a European private entity. Phoenix 1 is meant to test out essential technologies, including the company’s inflatable heat shield needed to return high-value cargo from space safely, the company noted. “Our mission is to revolutionise space logistics by enabling groundbreaking advancements in microgravity research, in-orbit manufacturing, defence applications, and life sciences,” says the firm’s website. The successful reentry and splashdown will support future commercial applications across these sectors.

Phoenix 1 shared the ride with several other payloads, including 425Sat-3, operated by South Korea’s Agency for Defence Development, and Tomorrow-S7, a weather satellite from the meteorological technology company Tomorrow Companies Inc. These collaborative launches are part of SpaceX’s growing commitment to enabling diverse and cost-effective access to low Earth orbits via its ridesharing programs. The Bandwagon missions, which began in April 2024 and continued with a second flight in December that year, operate alongside the long-established Transporter series, which has completed 13 missions since 2021.

Phoenix 1 Marks Shift Toward Scalable Reentry Missions in European Space Logistics

While the Transporter program is known for launching a large number of satellites—including a record-breaking 143 on a single flight in January 2021—the Bandwagon series focuses on smaller, more flexible ridesharing configurations. The dispatch of Phoenix 1 on Bandwagon 3 is the latest sign of a trend toward greater mission flexibility to develop and operate bespoke space technologies in support of different kinds of space exploration and logistics, and yet another indication of commercial innovation extending the boundaries of the possible in space.

A successful test flight of Phoenix 1 would have significant ramifications for European space companies, being positioned as proof of the Phoenix program—demonstrating mission-critical capabilities regarding return flights and retrofitting, while being the seed for a scalable reaping capability for research institutions and commercial entities.
