ESA’s first human spaceflight mission lifted off 40 years ago today. Accompanied by the first ESA astronaut, Ulf Merbold, the Spacelab module took flight inside the Space Shuttle’s cargo bay, turning NASA’s ‘space truck’ into a mini-space station for scientific research. Europe continues to be highly active in the crewed module business to this day.

In 2003, an unidentified flying object, comparable in size to a football field, reportedly hovered over Vandenberg Air Force Base, as disclosed during a House Oversight Committee's national security subcommittee hearing on UFOs. The hearing, held on Wednesday, delved into UFOs, now termed "unidentified anomalous phenomena" by the U.S. government.
The proceedings included whistleblower accounts that shed light on purported government UFO programs spanning multiple decades, according to retired major David Grusch. Former Navy fighter jet pilot Ryan Graves, founder of the non-profit Americans for Safe Aerospace, presented testimony regarding the alleged UFO sighting at Vandenberg.
During questioning by Representative Anna Paulina Luna, Graves recounted the 2003 incident: "In the 2003 timeframe, a sizable group of Boeing contractors near a launch facility at Vandenberg observed a large, 100-yard-sided red square approaching from the ocean. It hovered at low altitude over the launch facility for about 45 seconds before rapidly darting off over the mountains around 8:45 a.m."
Graves further described a subsequent event 24 hours later, involving additional sightings on the base, with some objects displaying aggressive behavior toward security guards. The information, according to Graves, came from a witness who approached him at Americans for Safe Aerospace, and this witness possessed documented police blotter and records from the 2003 incidents.
Testimonies from former Major Grusch and ex-U.S. intelligence officer David Fravor were also part of the hearing, although they refrained from answering certain questions. Representative Tim Burchett emphasized the importance of government transparency in addressing the issue, clarifying that the aim was to uncover facts without sensationalizing the subject.

Tundra wetlands are shown in late spring at the Yukon Delta National Wildlife Refuge in Alaska. Scientists are studying how fire and ice drive methane emissions in the Yukon-Kuskokwim Delta, within which the refuge is located.U.S. Fish and Wildlife Service Methane ‘hot spots’ in the Yukon-Kuskokwim Delta are more likely to be found where recent wildfires burned into the tundra, altering carbon emissions from the land.
In Alaska’s largest river delta, tundra that has been scorched by wildfire is emitting more methane than the rest of the landscape long after the flames died, scientists have found. The potent greenhouse gas can originate from decomposing carbon stored in permafrost for thousands of years. Its release could accelerate climate warming and lead to more frequent wildfires in the tundra, where blazes have been historically rare.
The new study was conducted by a team of scientists working as part of NASA’s Arctic-Boreal Vulnerability Experiment (ABoVE), a large-scale study of environmental change in Alaska and Western Canada. Researchers found that methane hot spots were roughly 29% more likely to occur in tundra that had been scorched by wildfire in the past 50 years compared to unburned areas. The correlation nearly tripled in areas where a fire burned to the edge of a lake, stream, or other standing-water body. The highest ratio of hot spots occurred in recently burned wetlands.
The researchers first observed the methane hot spots using NASA’s next-generation Airborne Visible/Infrared Imaging Spectrometer (AVIRIS-NG) in 2017. Mounted on the belly of a research plane, the instrument has an optical sensor that records the interaction of sunlight with molecules near the land surface and in the air, and it has been used to measure and monitor hazards ranging from oil spills to crop disease.
Methane bubbles pop on the surface of an Alaskan lake being studied by scientists with NASA’s Arctic-Boreal Vulnerability Experiment. A potent greenhouse gas, methane is released in bubble seeps when microbes consume carbon released from thawing permafrost.NASA/Kate Ramsayer Roughly 2 million hot spots – defined as areas showing an excess of 3,000 parts per million of methane between the aircraft and the ground – were detected across some 11,583 square miles (30,000 square kilometers) of the Arctic landscape. Regionally, the number of hot spot detections in the Yukon-Kuskokwim Delta were anomalously high in 2018 surveys, but scientists didn’t know what was driving their formation.
Ice and Fire
To help fill this gap, Elizabeth Yoseph, an intern at the time with the ABoVE campaign, focused on a methane-active region located in a wet and peaty area of the massive delta. Yoseph and the team used the AVIRIS-NG data to pinpoint hot spots across more than 687 square miles (1,780 square kilometers), then overlaid their findings on historical wildfire maps.
“What we uncovered is a very clear and strong relationship between fire history and the distribution of methane hot spots,” said Yoseph, lead author of the new study.
The connection arises from what happens when fire burns into the carbon-rich frozen soil, or permafrost, that underlies the tundra. Permafrost sequesters carbon from the atmosphere and can store it for tens of thousands of years. But when it thaws and breaks down in wet areas, flourishing microbes feed on and convert that old carbon to methane gas. The saturated soils around lakes and wetlands are especially rich stocks of carbon because they contain large amounts of dead vegetation and animal matter.

Rare but Increasing Risk
Because of the cool marshes, low shrubs, and grasses, tundra wildfires are relatively rare compared to those in other environments, such as evergreen-filled forests. However, by some projections the fire risk in the Yukon-Kuskokwim Delta could quadruple by the end of the century due to warming conditions and increased lightning storms – the leading cause of tundra fires. Two of the largest tundra fires on record in Alaska occurred in 2022, burning more than 380 square miles (100,000 hectares) of primarily tundra landscapes.
More research is needed to understand how a future of increasing blazes at high latitudes could impact the global climate. Arctic permafrost holds an estimated 1,700 billion metric tons of carbon – roughly 51 times the amount of carbon the world released as fossil fuel emissions in 2019.
All that stored carbon also means that the carbon intensity of fire emissions from burning tundra is extremely high, said co-author Elizabeth Hoy, a fire researcher at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Tundra fires occur in areas that are remote and difficult to get to, and often can be understudied,” she noted. “Using satellites and airborne remote sensing is a really powerful way to better understand these phenomena.”
The scientists hope to continue exploring methane hot spots occurring throughout Alaska. Ground-based investigation is needed to better understand the links between fire, ice, and greenhouse gas emissions at the doorstep of the Arctic.
The study was published in the journal Environmental Research Letters.
