The Expedition 72 crew is getting ready for a pair of missions next week to relocate a Dragon spacecraft to a new port then receive a new Dragon cargo delivery. The seven International Space Station residents also continued a host of space biology studies while maintaining the upkeep of the orbital lab on Thursday.

NASA Flight Engineer Nick Hague will command the SpaceX Dragon Freedom spacecraft this weekend taking NASA astronauts Suni Williams and Butch Wilmore and Roscosmos cosmonaut Aleksandr Gorbunov on a short ride to a new port. The quartet will undock from the Harmony module’s forward port at 6:35 a.m. EST on Sunday inside Freedom then relocate to Harmony’s adjacent space-facing port at 7:18 a.m.

The relocation maneuver opens up Harmony’s forward port for the next Dragon cargo mission due to launch at 9:29 p.m. on Monday from Kennedy Space Center in Florida. Dragon, carrying nearly 6,000 pounds of new science experiments and crew supplies, will arrive at the orbital outpost for an automated docking to Harmony’s forward port at 10:15 a.m. on Tuesday. Hague, Williams, and Wilmore joined NASA Flight Engineer Don Pettit and called down to mission controllers on Thursday and discussed the upcoming cargo operations. Hague and Wilmore also will be on duty Tuesday morning monitoring Dragon’s approach and docking.

The NASA quartet along with the three Roscosmos cosmonauts aboard the orbital outpost still kept up their critical research responsibilities informing ways to continuously improve human health of space crews and humans on Earth.

Hague began his day exploring the cardiovascular risk of living in space by attaching electrodes to his chest, scanning his arteries with an ultrasound device, then measuring his blood pressure. Pettit attached filters to a unique incubator located in the Kibo laboratory module that can generate artificial gravity. Afterward, Pettit imaged Hague’s retina, cornea, and optic nerve using standard medical imaging gear found in a doctor’s office.

Expedition 72 Commander Williams removed components from inside the Spectrum biology imaging device that captures fluorescent imagery of biological samples to track space-caused physiological changes. Station Flight Engineer Wilmore opened up BEAM, the Bigelow Expandable Activity Module, and entered the cargo stowage module replacing particle filters and swabbed surfaces to collect potential microbe samples for analysis.

Roscosmos Flight Engineers Alexey Ovchinin and Ivan Vagner continued their weeklong maintenance and inspection tasks in the aft end of the Zvezda service module. The duo also took turns attaching electrodes to themselves recording their heart activity and measuring their blood pressure. Flight Engineer Aleksandr swapped out a lens on a student-controlled Earth observation camera then serviced gas supply valves for the Plasma Kristall-4 space physics investigation.

International SWOT Satellite Spots Planet-Rumbling Greenland Tsunami

International SWOT Satellite Spots Planet-Rumbling Greenland Tsunami

SWOT data visualization
A SWOT data visualization shows water on the northern side of Greenland’s Dickson Fjord at higher levels than on the southern side on Sept. 17, 2023. A huge rockslide into the fjord the previous day led to a tsunami lasting nine days that caused seismic rumbling around the world.
NASA Earth Observatory

Data from space shows water tilting up toward the north side of the Dickson Fjord as it sloshed from south to north and back every 90 seconds for nine days after a 2023 rockslide.

The international Surface Water and Ocean Topography (SWOT) satellite mission, a collaboration between NASA and France’s CNES (Centre National d’Études Spatiales), detected the unique contours of a tsunami that sloshed within the steep walls of a fjord in Greenland in September 2023. Triggered by a massive rockslide, the tsunami generated a seismic rumble that reverberated around the world for nine days. An international research team that included seismologists, geophysicists, and oceanographers recently reported on the event after a year of analyzing data.

The SWOT satellite collected water elevation measurements in Dickson Fjord on Sept. 17, 2023, the day after the initial rockslide and tsunami. The data was compared with measurements made under normal conditions a few weeks prior, on Aug. 6, 2023.

In the data visualization (above), colors toward the red end of the scale indicate higher water levels, and blue colors indicate lower-than-normal levels. The data suggests that water levels at some points along the north side of the fjord were as much as 4 feet (1.2 meters) higher than on the south.

“SWOT happened to fly over at a time when the water had piled up pretty high against the north wall of the fjord,” said Josh Willis, a sea level researcher at NASA’s Jet Propulsion Laboratory in Southern California. “Seeing the shape of the wave — that’s something we could never do before SWOT.”

In a paper published recently in Science, researchers traced a seismic signal back to a tsunami that began when more than 880 million cubic feet of rock and ice (25 million cubic meters) fell into Dickson Fjord. Part of a network of channels on Greenland’s eastern coast, the fjord is about 1,772 feet (540 meters) deep and 1.7 miles (2.7 kilometers) wide, with walls taller than 6,000 feet (1,830 meters).

Far from the open ocean, in a confined space, the energy of the tsunami’s motion had limited opportunity to dissipate, so the wave moved back and forth about every 90 seconds for nine days. It caused tremors recorded on seismic instruments thousands of miles away.

From about 560 miles (900 kilometers) above, SWOT uses its sophisticated Ka-band Radar Interferometer (KaRIn) instrument to measure the height of nearly all water on Earth’s surface, including the ocean and freshwater lakes, reservoirs, and rivers.

“This observation also shows SWOT’s ability to monitor hazards, potentially helping in disaster preparedness and risk reduction,” said SWOT program scientist Nadya Vinogradova Shiffer at NASA Headquarters in Washington.

It can also see into fjords, as it turns out.

“The KaRIn radar’s resolution was fine enough to make observations between the relatively narrow walls of the fjord,” said Lee-Lueng Fu, the SWOT project scientist. “The footprint of the conventional altimeters used to measure ocean height is too large to resolve such a small body of water.”

More About SWOT

Launched in December 2022 from Vandenberg Space Force Base in California, SWOT is now in its operations phase, collecting data that will be used for research and other purposes.

The SWOT satellite was jointly developed by NASA and CNES, with contributions from the Canadian Space Agency (CSA) and the UK Space Agency. NASA’s Jet Propulsion Laboratory, managed for the agency by Caltech in Pasadena, California, leads the U.S. component of the project. For the flight system payload, NASA provided the KaRIn instrument, a GPS science receiver, a laser retroreflector, a two-beam microwave radiometer, and NASA instrument operations. CNES provided the Doppler Orbitography and Radioposition Integrated by Satellite (DORIS) system, the dual frequency Poseidon altimeter (developed by Thales Alenia Space), the KaRIn radio-frequency subsystem (together with Thales Alenia Space and with support from the UK Space Agency), the satellite platform, and ground operations. CSA provided the KaRIn high-power transmitter assembly. NASA provided the launch vehicle and the agency’s Launch Services Program, based at Kennedy Space Center in Florida, managed the associated launch services.

We Are All Made of Cells: Space and the Immune System

We Are All Made of Cells: Space and the Immune System

Bone cells
NASA

Malcolm O’Malley and his mom sat nervously in the doctor’s office awaiting the results of his bloodwork. This was no ordinary check-up. In fact, this appointment was more urgent and important than the SATs the seventeen-year-old, college hopeful had spent months preparing for and was now missing in order to understand his symptoms. 

But when the doctor shared the results – he had off-the-charts levels of antibodies making him deathly allergic to shellfish – O’Malley realized he had more questions than answers. Like: Why is my immune system doing this? How is it working? Why is it reacting so severely and so suddenly (he’d enjoyed shrimp less than a year ago)? And why does the only treatment – an injection of epinephrine – have nothing to do with the immune system, when allergies appear to be an immune system problem? Years later, O’Malley would look to answer some of these questions while interning in the Space Biosciences Research Branch at NASA’s Ames Research Center in California’s Silicon Valley.

“Anaphylaxis is super deadly and the only treatment for it is epinephrine; and I remember thinking, ‘how is this the best we have?’ because epinephrine does not actually treat the immune system at all – it’s just adrenaline,” said O’Malley, who recently returned to his studies as a Ph.D. student of Biomedical Engineering at the University of Virginia (UVA) in Charlottesville. “And there’s a thousand side effects, like heart attacks and stroke – I remember thinking ‘these are worse than the allergy!’”

O’Malley’s curiosity and desire to better understand the mechanisms and connections between what triggers different immune system reactions combined with his interest in integrating datasets into biological insights inspired him to shift his major from computer science to biomedical engineering as an undergraduate student. With his recent allergy diagnosis and a lifelong connection to his aunt who worked at the UVA Heart and Vascular Center, O’Malley began to build a bridge between the immune system and heart health. By the time he was a senior in college, he had joined the Cardiac Systems Biology Lab, and had chosen to focus his capstone project on better understanding the role of neutrophils, a specific type of immune cell making up 50 to 70% of the immune system, that are involved in cardiac inflammation in high blood pressure and after heart attacks.

“The immune system is involved in everything,” O’Malley says. “Anytime there’s an injury – a paper cut, a heart attack, you’re sick – the immune system is going to be the first to respond; and neutrophils are the first responders.”

O’Malley’s work to determine what regulates the immune system’s interrelated responses – like how one cell could affect other cells or immune processes downstream – provided a unique opportunity for him to support multiple interdisciplinary NASA biological and physical sciences research projects during his 10-week internship at NASA Ames over the summer of 2024. O’Malley applied machine learning techniques to the large datasets the researchers were using from experiments and specimens collected over many years to help identify possible causes of inflammation seen in the heart, brain, and blood, as well as changes seen in bones, metabolism, the immune system, and more when humans or other model organisms are exposed to decreased gravity, social isolation, and increased radiation. These areas are of keen interest to NASA due to the risks to human health inherent in space exploration and the agency’s plans to send humans on long-duration missions to the Moon, Mars, and beyond.

“It’s exciting that we just never know what’s going to happen, how the immune system is going to react until it’s already been activated or challenged in some way,” said O’Malley. “I’m particularly interested in the adaptive immune system because it’s always evolving to meet new challenges; whether it’s a pandemic-level virus, bacteria or something on a mission to Mars, our bodies are going to have some kind of adaptive immune response.”

During his NASA internship, O’Malley applied a statistical analysis techniques to plot and make more sense of the massive amounts of life sciences data. From there, researchers could find out which proteins, out of hundreds, or attributes – like differences in sex – are related to which behaviors or outcomes. For example, through O’Malley’s analysis, researchers were able to better pinpoint the proteins involved in inflammation of the brain that may play a protective role in spatial memory and motor control during and after exposure to radiation – and how we might be able to prevent or mitigate those impacts during future space missions and even here on Earth.

“I had this moment where I realized that since my internship supports NASA’s Human Research Program that means the work I’m doing directly applies to Artemis, which is sending the first woman and person of color to the Moon,” reflected O’Malley. “As someone who’s both black and white, representation is important to me. It’s inspiring to think there will be people like me on the Moon – and that I’m playing a role in making this happen.”

When O’Malley wasn’t exploring the mysteries of the immune system for the benefit of all at NASA Ames, he taught himself how to ride a bike and started to surf in the nearby waters of the Pacific Ocean. O’Malley considers Palmyra, Virginia, his hometown and he enjoys playing sports – especially volleyball, water polo, and tennis – reading science fiction and giving guest lectures to local high school students hoping to spark their curiosity. 

O’Malley’s vision for the future of biomedical engineering reflects his passion for innovation. “I believe that by harnessing the unique immune properties of other species, we can achieve groundbreaking advancements in limb regeneration, revolutionize cancer therapy, and develop potent antimicrobials that are considered science fiction today,” he said.

Witch Nebula Casts Starry Spell

NASA/JPL-Caltech

This 2013 image taken by NASA’s Wide-Field Infrared Survey Explorer, or WISE, captures a nebula that looks like a witch screaming. Perhaps that imagined scream is a creation spell, for the Witch Hat nebula’s billowy clouds are a star nursery. We can see these clouds thanks to massive stars lighting them up; dust in the cloud is being hit with starlight, causing it to glow with infrared light, which was picked up by WISE’s detectors.

WISE launched to near-Earth orbit on Dec. 14, 2009, and surveyed the full sky in four infrared wavelength bands until the frozen hydrogen cooling the telescope was depleted in September 2010. The spacecraft was placed into hibernation in February 2011, having completed its primary astrophysics mission.

In late 2013, the spacecraft was resurrected – no incantation needed – when NASA’s Planetary Science Division gave it a new mission and a new name: NEOWISE. The spacecraft began helping NASA identify and describe near-Earth objects (NEOs). NEOs are comets and asteroids that have been nudged into orbits that allow them to enter Earth’s neighborhood. NEOWISE was decommissioned Aug. 8, 2024, and placed into hibernation for the last time, ending its career as an active asteroid hunter.
