NASA Selects UB Scientists for a Revolutionary Satellite Mission
A team of scientists from the University of Buffalo (UB) is about to embark on an extraordinary journey to explore our planet's frozen frontiers. NASA has chosen UB's Sophie Nowicki and Beata Csatho to join an international mission that will revolutionize how we study Earth's ice sheets and ecosystems.
The mission, known as the Earth Dynamics Geodetic Explorer (EDGE), is set to launch no earlier than 2030, with a budget of up to $355 million. EDGE is one of two selected projects from NASA's Earth System Explorers (ESE) program, which aims to address critical scientific and national priorities.
But here's the game-changer: EDGE will be the world's first global satellite imaging laser altimeter system. This cutting-edge technology shoots laser pulses at Earth's surface and measures the time it takes for them to bounce back, creating high-resolution 3D images of forests, glaciers, ice sheets, and sea ice.
"We need to delve deeper into the mysteries of ice sheets to predict sea-level rise more accurately," says Professor Csatho. "EDGE will provide the precision and detail needed to study these critical processes." The mission will focus on the rapidly changing regions at the edges of ice sheets, where many unknowns remain.
Building on the success of NASA's ICESat-2 and GEDI missions, EDGE takes laser altimetry to the next level. It will map the planet using five 120-meter-wide strips, providing an unprecedented level of detail. This high-resolution data will enable scientists to monitor changes in ice sheets and contribute to numerical models, with the potential for AI integration.
Nowicki and Csatho are no strangers to NASA missions, having participated in previous satellite altimeter projects. On EDGE, they will play pivotal roles in land ice product development and cryosphere applications, respectively, ensuring the data benefits communities worldwide.
"From assessing coastal flood risks to ensuring water quality, the applications of EDGE data are vast," Nowicki explains. "Our goal is to empower communities with actionable insights to build a more resilient future."
The EDGE spacecraft, a Lanteris 500 series, will be led by Professor Helen Amanda Fricker from UC San Diego, with a diverse team of deputy investigators and scientists from various institutions. This collaboration is a testament to the global effort required to tackle Earth's most pressing challenges.
And this is where it gets intriguing: Could EDGE's data reveal hidden patterns in Earth's climate systems, leading to groundbreaking discoveries? The mission promises to unlock new insights, but what implications might these findings have for our understanding of the planet's future?
