Jet Propulsion Laboratory (JPL), NASA

What JPL Does

JPL's primary function is to conceive, design, build, and operate robotic missions that explore our solar system and the universe. This end-to-end responsibility covers the entire lifecycle of a mission, from its initial scientific conception to the analysis of the data returned from distant worlds. The laboratory's expertise spans several key areas:

• Robotic Space Exploration: JPL is synonymous with robotic exploration. It has sent spacecraft to every planet in our solar system and into interstellar space. This includes iconic missions to Mars, such as the Curiosity and Perseverance rovers, and the Ingenuity helicopter, which demonstrated the first powered, controlled flight on another planet. Missions like the Voyager probes, now in interstellar space, and the Galileo and Juno missions to Jupiter, have revolutionized our understanding of the outer solar system.

• Earth Science: While renowned for its deep-space missions, JPL also plays a crucial role in studying our home planet. It develops and operates a fleet of Earth-observing satellites and instruments that monitor our climate, weather patterns, oceans, and landmasses. This data is vital for understanding climate change, managing natural resources, and responding to natural disasters.

• Astrophysics and Astronomy: JPL develops technologies and instruments for space-based observatories that peer into the cosmos. It has contributed significantly to projects like the Hubble Space Telescope and the Spitzer Space Telescope. These missions aim to answer fundamental questions about the origins of the universe, the nature of dark energy and dark matter, and the search for exoplanets.

• Technology Development and Innovation: Underpinning all of JPL's missions is a relentless drive for technological innovation. The laboratory is a hotbed of research and development in areas such as robotics, artificial intelligence, advanced propulsion systems, and miniaturized spacecraft components. Many of these innovations have applications beyond space exploration, benefiting society in various ways.

Products and Services

JPL's "products" are the tangible hardware and software it creates, while its "services" encompass the expertise and capabilities it provides to NASA and the scientific community.

Products

• Spacecraft and Rovers: JPL's most famous products are the robotic explorers it builds. These are highly complex and customized machines designed to operate in extreme environments. Examples range from large, sophisticated orbiters and landers to agile rovers and compact CubeSats. Each spacecraft is a unique creation, tailored to the specific scientific goals of its mission.

• Scientific Instruments: JPL designs and fabricates a wide array of advanced scientific instruments for its own missions and for those of other space agencies. These instruments include high-resolution cameras, spectrometers to analyze chemical compositions, radar systems to map surfaces, and sensors to measure atmospheric conditions. These instruments are the eyes, ears, and hands of the spacecraft, enabling them to collect invaluable scientific data.

• Software and AI: A significant part of any JPL mission is the sophisticated software that controls the spacecraft and analyzes the data it returns. This includes autonomous navigation systems that allow rovers to traverse hazardous terrain on their own and artificial intelligence algorithms that can identify scientifically interesting features in images and data.

• Technology Spinoffs: Technologies developed for space exploration often find applications here on Earth. JPL has a long history of "spinoffs" that have entered the commercial market. A notable example is the development of the active pixel sensor, a technology that is now at the heart of most digital cameras, including those in smartphones.

Services

• Mission Design and Management: JPL offers unparalleled expertise in the design, development, and management of complex space missions. This service covers all phases of a project, from initial concept studies and feasibility assessments to the day-to-day operations of the spacecraft. This includes a rigorous process of systems engineering, risk management, and quality assurance to ensure mission success.

• The Deep Space Network (DSN): Operated by JPL for NASA, the Deep Space Network is a global system of large radio antennas that provides the crucial two-way communication link for interplanetary spacecraft. The DSN allows mission controllers to send commands to spacecraft and receive the scientific data they collect. This network is a critical asset not just for NASA missions but also for those of international partners.

• Navigation and Trajectory Analysis: Getting a spacecraft to a distant planet requires incredibly precise navigation. JPL's navigation teams are world leaders in calculating and maintaining the trajectories of spacecraft, ensuring they arrive at their destinations millions of miles away with pinpoint accuracy.

• Scientific Data Analysis and Archiving: Once data is returned from a mission, JPL scientists and engineers play a key role in processing, analyzing, and interpreting it. The laboratory also manages the Planetary Data System (PDS), which archives and distributes the vast amounts of data collected by NASA's planetary missions, making it accessible to researchers worldwide.
