Listen to this audio excerpt from Jen Madsen and Trey Perryman, leads of the Orion Mission Evaluation Room for the Artemis II mission:

0:00 / 0:00

During NASA’s Artemis II mission, Jen Madsen and Trey Perryman will be leading a team monitoring the Orion spacecraft as it carries four astronauts around the Moon. The team works in the Orion Mission Evaluation Room where they will monitor and analyze Orion’s systems and performance in real time to help ensure crew safety and mission success.

As the leaders of the Orion Mission Evaluation Room located inside the Mission Control Center at NASA’s Johnson Space Center in Houston, Madsen and Perryman are responsible for ensuring that the dozens of NASA, Lockheed Martin, ESA (European Space Agency), and Airbus expert engineers that staff the room’s consoles are ready for Artemis II.

Jen and I are responsible for the organization, training, and execution of the entire team. We’ll also play a key role in communicating the findings of the Mission Evaluation Room to our program and agency leadership.

Lead for Orion Mission and Systems Integration

The flight control team operating Orion from mission control’s White Flight Control Room will rely on the Mission Evaluation Room’s crucial findings to help with unexpected spacecraft behaviors that may arise and help analyze Orion’s performance data during the mission.

With crew aboard Orion, Artemis II brings new challenges, new opportunities, and a new space in mission control for the Orion Mission Evaluation Room. More spacecraft systems will be put to the test, requiring more evaluation room expertise and new consoles to monitor systems not previously flown, like life support.

“There’s loads of excitement — for the new capabilities, the mission, and having a new, wonderful space to operate in,” said Perryman.

Besides leading the Mission Evaluation Room, Perryman is also the lead for Orion Mission and Systems Integration, and Madsen is deputy manager for Orion’s Avionics, Power, and Software. Their co-leadership styles complement each other — Perryman leads with energy and team spirit, while Madsen brings a steadiness and structure.

“We balance each other out,” Madsen said. “And that balance is reflected in our team.”

For Perryman, a former flight controller with a background in space shuttle and space station operations, the MER represents the culmination of a career in human spaceflight that’s personal.

“I couldn’t imagine being anywhere else right now,” Perryman said. “My wife and I have four boys, and my boys are very excited about Artemis…that’s meaningful to me. And they like seeing a father who’s really connected to this mission.”

Madsen began her NASA career in engineering, designing and simulating Orion’s guidance, navigation, and control systems early on in the program.

I spent many years doing computer simulations, writing code, doing analysis… we designed, built, and tested Orion. So now it’s amazing to me to get to be a part of the legacy of operating the vehicle.

For both leaders, the Artemis II mission is more than technical. With crew flying aboard the spacecraft, it’s deeply human.

“I do feel an extra sense of importance and mindfulness about what we’re doing in this building,” Perryman said,  “making sure — specifically in the Orion MER — that we understand how the vehicle supports the crew, because it is so important to return them home safely.”

“We all feel like Reid, Victor, Christina, and Jeremy are part of the Orion family,” Madsen said. “When we have discussions about risk, from design all the way through operations, we’re thinking about our friends aboard the spacecraft.”

In this Oct. 20, 2025, photo, tiny ball bearings surround a larger central bearing during the Fluid Particles experiment, conducted inside the Microgravity Science Glovebox (MSG) aboard the International Space Station’s Destiny laboratory module. A bulk container installed in the MSG, filled with viscous fluid and embedded particles, is subjected to oscillating frequencies to observe how the particles cluster and form larger structures in microgravity. Insights from this research may advance fire suppression, lunar dust mitigation, and plant growth in space. On Earth, the findings could inform our understanding of pollen dispersion, algae blooms, plastic pollution, and sea salt transport during storms.

In addition to uncovering potential benefits on Earth, research done aboard the space station helps inform long-duration missions like Artemis and future human expeditions to Mars.

OPERA: Addressing Societal Needs with Satellite Data

Introduction

The Observational Products for End-Users from Remote Sensing Analysis (OPERA) project represents a strategic initiative designed to address critical satellite data needs identified by federal agencies. Established in 2021 by the NASA/Jet Propulsion Laboratory (JPL), OPERA responds to priorities identified by the Satellite Needs Working Group (SNWG), an interagency body convened by the White House Office of Management and Budget (OMB) and Office of Science and Technology Policy (OSTP). SNWG surveys federal agencies every two years to determine their top satellite data needs. This article summarizes OPERA, including its mandate, and then presents a case study demonstrating how the United States Department of Agriculture (USDA) Agricultural Research Service (ARS) is using OPERA to monitor agricultural health in the Midwestern United States.

OPERA Mandate and Approach

The core mandate for the OPERA project lies in its commitment to delivering data products in formats that are immediately usable and analysis-ready. Rather than providing raw satellite data that requires extensive processing expertise, OPERA transforms complex satellite observations into standardized, accessible products that federal agencies can quickly integrate into their existing workflows to support national security, environmental monitoring, disaster response, and infrastructure management. This approach eliminates the technical barriers that often prevent agencies from effectively using satellite data, allowing them to focus on their mission-critical applications rather than data processing challenges.

To achieve this goal at the scale required by federal agencies, OPERA has developed a sophisticated cloud-based production system capable of generating data products efficiently and consistently to meet the dynamic needs of federal users. As of 2025, OPERA has successfully released dynamic surface water extent, surface disturbance, and surface displacement data through various NASA Distributed Active Archive Centers (DAACs). The vertical land motion product will be OPERA’s next offering beginning in 2028 – see Figure 1.

OPERA Mission

OPERA delivers high-quality, ready-to-use satellite-derived information to enable federal agencies to better monitor environmental changes, respond to natural disasters, assess infrastructure risks, and make data-driven decisions. To illustrate this goal, OPERA’s 5th Annual Stakeholder Engagement Workshop detailed real-world applications of this approach on Sept. 11, 2025.

Case Study: Harnessing OPERA Data to Map Crop Health in Midwest United States

When water lingers on farmland, the consequences often ripple outward, resulting in crop losses, changes in soil health, and shifting carbon storage. In the rolling landscape of central Iowa’s South Fork watershed, these challenges are a daily reality for farmers, researchers, and crop insurance companies. To address these concerns, scientists at the U.S. Department of Agriculture–Agriculture Research Service’s (USDA–ARS) National Laboratory for Agriculture and the Environment (NLAE) are partnering with NASA’s OPERA project.

Using OPERA’s Dynamic Surface Water Extent (DSWx) and Surface Disturbance (DIST) product suites, USDA–NLAE researchers began the process of identifying depressions where water consistently ponds across fields – see Figure 2.

These sites are often more than nuisance puddles; they signal areas of reduced yield, risk for crop mortality, and hotspots for carbon and nutrient accumulation. By combining OPERA’s cloud-free, high-resolution mosaics with field-based measurements from USDA and university partners, the joint OPERA-NLAE team is producing actionable maps that pinpoint waterlogged zones – see Figure 3. Farmers can use these maps to improve soil health and guide land-management decisions.

OPERA Figure 3
Figure 3. The map depicts a field south of Iowa Falls in Hardin County, IA. The pixels are color-coded to indicate the number of times a region is inundated with water from May through October 2024. Larger numbers are associated with deeper depressions and with perennial lakes and rivers, including the Iowa River flowing west to east in the northern part of the image.

The OPERA products also support broader watershed management. Analyses of river migration, oxbow lake formation, and storm damage from powerful Midwestern derecho events show how OPERA data extend beyond field plots to larger areas. By detecting both persistent inundation and shifts in vegetation health, DSWx and DIST together provide synergistic information identifying areas where improved tile drainage may result in better crop health and increased yields. This approach can also be used to mitigate topsoil erosion and nutrient transport to control the development of harmful algal blooms and the occurrence of anoxic zones with implications far beyond the Mississippi Delta.

Conclusion

The use of OPERA data by USDA–ARS to map and monitor crop health in the Midwest United States highlights how this vital data product bridges the gap between Earth science and agricultural resilience. The outcome of this collaboration underscores OPERA’s mission – translating cutting-edge satellite observations into usable tools that support farmers, improve soil and water conservation, and strengthen the resilience of U.S. agriculture. This collaboration signifies the mandate of OPERA as an SNWG solution provider to fulfill the observation needs of federal users. All OPERA’s data products are freely available to the public from various NASA DAACs and are discoverable from the NASA Earthdata Search platform. The team welcomes direct engagement with individual federal, state, academic, and commercial stakeholders and can be reached via opera.sep@jpl.nasa.gov.
