Scientists at the University of Houston have found a new understanding of climate and weather on Mars.

The study, which was published in a new paper in AGU Advances and will be featured in AGU’s science magazine EOS, generated the first meridional profile of Mars’ radiant energy budget (REB). REB represents the balance or imbalance between absorbed solar energy and emitted thermal energy across latitudes. An energy surplus can lead to global warming, and a deficit results in global cooling, which helps provide insights to Earth's atmospheric processes too. The profile of Mars’ REB influences weather and climate patterns.

The study was led by Larry Guan, a graduate student in the Department of Physics at UH's College of Natural Sciences and Mathematics under the guidance of his advisors Professor Liming Li from the Department of Physics and Professor Xun Jiang from the Department of Earth and Atmospheric Sciences and other planetary scientists. UH graduate students Ellen Creecy and Xinyue Wang, renowned planetary scientists Germán Martínez, Ph.D. (Houston’s Lunar and Planetary Institute), Anthony Toigo, Ph.D. (Johns Hopkins University) and Mark Richardson, Ph.D. (Aeolis Research), and Prof. Agustín Sánchez-Lavega (Universidad del País, Vasco, Spain) and Prof. Yeon Joo Lee (Institute for Basic Science, South Korea) also assisted in the project.

The profile of Mars’ REB is based on long-term observations from orbiting spacecraft. It offers a detailed comparison of Mars’ REB to that of Earth, which has shown differences in the way each planet receives and radiates energy. Earth shows an energy surplus in the tropics and a deficit in the polar regions, while Mars exhibits opposite behavioral patterns.

The surplus is evident in Mars’ southern hemisphere during spring, which plays a role in driving the planet’s atmospheric circulation and triggering the most prominent feature of weather on the planet, global dust storms. The storms can envelop the entire planet, alter the distribution of energy, and provide a dynamic element that affects Mars’ weather patterns and climate.

The research team is currently examining long-term energy imbalances on Mars and how it influences the planet’s climate.

“The REB difference between the two planets is truly fascinating, so continued monitoring will deepen our understanding of Mars’ climate dynamics,” Li says in a news release.

The global-scale energy imbalance on Earth was recently discovered, and it contributes to global warming at a “magnitude comparable to that caused by increasing greenhouse gases,” according to the study. Mars has an environment that differs due to its thinner atmosphere and lack of anthropogenic effects.

“The work in establishing Mars’ first meridional radiant energy budget profile is noteworthy,” Guan adds. “Understanding Earth’s large-scale climate and atmospheric circulation relies heavily on REB profiles, so having one for Mars allows critical climatological comparisons and lays the groundwork for Martian meteorology.”

European spacecraft developer expands to Houston with U.S. business, new lab

houston hq

European aerospace manufacturer The Exploration Company has established its first U.S. entity and named Space City as its headquarters.

The company announced earlier this month that it has launched TEC Federal to support U.S. government customers and agencies, and to scale The Exploration Company's engineering operations in the country.

Mark Kirasich serves as president of TEC Federal. Kirasich most recently served as the senior director of human spaceflight at Blue Origin after a nearly 40-year career at NASA.

The Exploration Company is developing the reusable Nyx space vehicle. Nyx is designed to take off from any heavy launcher in the world. It will then dock at space stations, retrieve up to 3,000 kilograms of cargo, splash down and return the cargo to Earth. The company aims to make Nyx fully reusable for up to 10 missions, making it a more affordable and sustainable option for aerospace missions.

The Exploration Company completed a successful drop test of the spacecraft in May in the Mojave Desert. The company says Nyx is slated to perform its first flight demonstration in 2028.

In addition to launching the Houston business, The Exploration Company also opened its new Rapid Innovation Lab near Houston's NASA Johnson Space Center on Space Park Drive.

The Rapid Innovation Lab features a full-scale mockup of the future Nyx crew capsule as well as ongoing development and testing of the Nyx cargo capsule, according to the company.

The Exploration Company says the new lab will allow its engineers, designers, and operators to prototype and test crew interfaces. It will also support partnerships with NASA personnel and astronauts.

“Houston gives us direct access to the people and expertise that have built and operated human spaceflight systems for decades. We’re excited to invest and expand around that— engineers, operators, and astronauts working together and moving quickly towards building a crew capsule.” Hélène Huby, founder and CEO of The Exploration Company, said in a blog post.

According to The Houston Chronicle, The Exploration Company has about 30 employees in the Houston area.

The company was founded in 2021 by Huby, a French rocket scientist, and has raised more than $350 million in venture capital. It operates out of Germany, France, Luxembourg, Spain and Italy, with offices in the U.S. and the United Arab Emirates. It is also developing a reusable, high-thrust rocket engine known as Storm.

UH lands $4M NIH grant to study early signs of autoimmune disease

NIH funding

The University of Houston recently received a $4 million National Institutes of Health grant to support a 10-year longitudinal study to identify the earliest biological markers of autoimmune disease.

Led by Chandra Mohan, the Hugh Roy and Lillie Cranz Cullen Endowed Professor of Biomedical Engineering, the study aims to examine what causes Systemic Autoimmune Rheumatic Diseases (SARDs) and to identify targets for future treatments. The study will be carried out in collaboration with Dr. Karen Costenbader at Harvard Medical School, Boston.

SARDs include conditions like rheumatoid arthritis, systemic lupus erythematosus, Sjögren’s syndrome and systemic sclerosis—all are considered chronic diseases currently without a cure. Autoimmune diseases affect over 30 million people globally, according to UH.

SARDs occur when the body’s immune system attacks healthy, non-threatening tissues and organs. According to UH, in these diseases, the body often attacks nuclear antigens, creating anti-nuclear autoantibodies, which can be early detection signs for SARDs in more than 50 percent of patients, Mohan says.

Researchers will study blood samples and environmental exposure over the 10 years to better understand anti-nuclear autoantibodies.

“Collectively, these studies will help identify the genetic, environmental and cellular factors that are operative at the two steps of SARD development, namely the emergence of anti-nuclear autoantibodies and disease onset,” Mohan said in a news release. “ More importantly, these studies will highlight functional molecular pathways and mechanisms that may be operative at each step."

Mohan predicts that looking at SARDs’ shared characteristics, rather than each disease individually, could help identify more treatment methods.

“Individual SARDs have been examined in silos without an attempt to discern shared underlying features at the molecular level,” he added in the release. “Current understanding of the initial (and likely shared) origins of SARDs is only rudimentary but urgently needed to develop means for prevention and treatment.”

Earlier this year, UH also received an $11 million NIH grant to conduct a first-of-its-kind study of early language development in children ages 18 to 24 months. Read more here.
