Marie Ivanco, an aerospace engineer and decision science expert, explains how she tackles the challenges of designing new science mission architectures in a way that meets objectives from interested parties around the world. Credits: NASA Jet Propulsion Laboratory.
As the number of satellites in orbit grows, NASA needs to understand how they might collaborate to help answer big questions about space science. Aerospace engineer Ben Merrel talks about his work exploring the reliability and effectiveness of satellite constellations.
Chase Lynch is focused on helping to create crew timelines, particularly when it comes to maintaining the systems that make off-world living possible. Find out where he discovered a treasure-trove of maintenance data to help inform his work.
Several United States government agencies utilize space to achieve their organizational goals, but how do these different organizations achieve mutual cooperation in space? We discuss this and more with SMAB analyst Gregory Benjamin. Credits: NASA.
What does it take to send astronauts to and from Mars? We discuss the challenges of designing a crewed Mars mission with SMAB engineer Patrick Chai, the lead of NASA Langley Research Center’s Mars Architecture Team. Credits: NASA/Advanced Concepts Laboratory.
Astronauts will be staying for longer periods of time on the Moon. Melanie Grande has imagined a sustainable way to keep them safe while they're living and working there.
What’s the right orbit for a satellite to provide the best science possible? We talk with SMAB engineer Vianni Ricano Cadenas about her work aiding the NASA Earth Science Division. Credits: NASA Jet Propulsion Lab
Tim Lewis is both a strategic and systems thinker. He doesn’t make decisions about engineering or science, but he is responsible for building a consensus that enables those decisions to be made.

Branch Core Capabilities

Space Concepts, Analysis, & Assessments

Campaigns

We evaluate integrated sequences of missions over extended periods of time against technical and programmatic objectives.

We generate comprehensive risk assessments on space system supportability and affordability.

Integrated Architectures

We develop integrated architectures that blend system and mission concepts to achieve long-term exploration, science, and technology development goals.

Missions

We design and assess end-to-end space missions using in-house and commercial off-the-shelf tools.

We provide high fidelity mission simulation and visualization for space missions to enable detailed technical analysis and public engagement.

Vehicles

We support in-depth, multi-discipline design and analysis of concepts and vehicles from pre-formulation through operations.

Decision Analysis

We apply decision analysis methods to inform NASA decision makers for activities such as portfolio characterization and prioritization, trade space exploration and down-selection of design options, and cost-benefit analysis.

We develop independent decision models to enable traceable data-driven decisions.
