Artemis II and why repeated missions are essential to lunar success

Getting to the moon wasn’t a one-and-done kind of effort. It took repeated missions, each one teaching scientists and engineers something new, and each one making the next attempt a little smarter and a lot safer. That’s a big reason lunar success eventually became possible: people kept going back, gathering more data, fixing problems, and building confidence step by step.


With all eyes on the Artemis II mission's final hours, University of Delaware space professor Bennett Maruca can talk all things space exploration and the race to the moon. 


Have you ever wondered why Apollo 11 was named Apollo 11? It's because Apollo 1-10 were already taken! And mostly were fact-finding missions, with many barely leaving the ground, says Maruca. 


Space program launches can cost billions of dollars. In order to ensure that they are successful, trial runs need to take place. Space travel leaves very little room for guesswork, and even small mistakes can have serious consequences. By launching multiple missions, experts could spot weaknesses, improve hardware, and make sure astronauts were better protected before taking on even bigger risks. In a way, each mission was like a rehearsal that made the final performances much more reliable.

Experts on earthquake response, community recovery and building safety

The shaking from a major earthquake may be over in minutes, but its consequences will last for years. University of Delaware experts can address emergency response, distributing aid, assessing damaged buildings, helping vulnerable communities and planning for long-term recovery. Their expertise is particularly relevant as communities across Latin America respond to major earthquakes, including the deadly magnitude 7.4 earthquake in Colombia. Tricia Wachtendorf, co-director of UD’s Disaster Research Center, offers expertise on how governments, nonprofits, emergency responders and community groups coordinate following a major disaster. Her research examines the role of spontaneous or “emergent” groups, humanitarian aid and donations, and how communities and organizations respond in the aftermath of disasters. Jennifer Trivedi, associate professor of anthropology and Disaster Research Center faculty member, specializes in disaster vulnerability and why some communities are more severely affected than others. She also addresses the long-term recovery needs and planning that emerge after the immediate crisis. Michael Chajes, professor of civil and environmental engineering, provides expertise on the structural damage caused by earthquakes, why some buildings collapse while others withstand the shaking and how engineers assess damaged structures and improve earthquake resilience.

Mapping the ancient world with underwater robotics

As audiences flock to theaters for Christopher Nolan's The Odyssey, University of Delaware professor Art Trembanis is leading a real-life expedition to uncover one of ancient Greece's most important maritime landscapes. Trembanis, a professor in UD's School of Marine Science and Policy and an expert in seafloor mapping, marine robotics and underwater sensing technologies, recently led a team of students and researchers to the ancient harbor of Kenchreai, where they deployed autonomous underwater vehicles, advanced sonar systems and other cutting-edge mapping technologies to document a harbor that has remained hidden beneath the Mediterranean Sea for centuries. The expedition collected geospatial data that will allow researchers to reconstruct the ancient port in remarkable detail and ultimately create a "digital twin" of the site. The virtual model will enable archaeologists, engineers, students and the public to explore the harbor as if the water had been removed, preserving an invaluable piece of cultural heritage while advancing the use of marine technology in archaeology. Trembanis can discuss: Marine robotics and autonomous underwater vehicles Seafloor mapping and underwater imaging technologies The use of digital twins and 3D modeling to study underwater environments Advances in marine geospatial technology and ocean exploration Underwater archaeology and documenting submerged cultural heritage How engineering and marine science are transforming the study of oceans and ancient landscapes The role of emerging technologies in scientific discovery and education To arrange an interview with Trembanis, click on his profile or email mediarelations@udel.edu.

How Wildfires Impact Vulnerable Communities, Pets and Public Health Systems

Wildfires burning across the world, now in parts of France and Spain, are forcing hundreds of thousands of people to evacuate. University of Delaware experts are available to discuss wildfire evacuations, vulnerable communities, animal rescue and the health effects of wildfire smoke exposure. Those experts, from UD’s Disaster Research Center, include: Sarah DeYoung Professor of sociology and criminal justice: • How people are forced to make split-second decisions involving horses, livestock and companion animals during fast-moving wildfires. • Why some owners must turn animals loose when evacuation time is limited. • Lessons from past disasters and animal rescue research. Jennifer Trivedi Assistant professor of anthropology: • The unique challenges faced by vulnerable populations during wildfires. • Complications surrounding evacuation decision-making and evacuation needs. • Long-term recovery following catastrophic disasters. Jennifer Horney Chair of UD’s Department of Epidemiology: • Health risks associated with wildfire smoke exposure, including respiratory infections. • How wildfire smoke and airborne pollutants affect population health. • The strain major wildfires can place on public health and health care systems.
