NASA Near-Earth Object Program
Name	NASA Near-Earth Object Program
Organization	NASA
Location	Jet Propulsion Laboratory

NASA Near-Earth Object Program is a critical component of NASA's Planetary Defense efforts, working closely with the Federal Emergency Management Agency (FEMA), National Oceanic and Atmospheric Administration (NOAA), and the United States Air Force (USAF) to detect and track Near-Earth Objects (NEOs) such as Asteroids and Comets. The program collaborates with international partners like the European Space Agency (ESA), Canadian Space Agency (CSA), and the Japan Aerospace Exploration Agency (JAXA) to share resources and expertise. By leveraging the capabilities of Telescopes like the Pan-STARRS and Catalina Sky Survey, the program aims to identify potential threats to Earth and develop strategies for Deflection and Disruption.

Introduction

The NASA Near-Earth Object Program is a vital initiative that focuses on the detection, tracking, and characterization of Near-Earth Objects (NEOs) that could potentially impact Earth. The program works in conjunction with the Minor Planet Center (MPC), International Astronomical Union (IAU), and the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS) to ensure a coordinated global response to the Asteroid Impact Hazard. By utilizing advanced Radar Astronomy and Infrared Astronomy techniques, the program is able to accurately predict the orbits of NEOs and assess their potential threat to Human Spaceflight and Satellite operations. The program also collaborates with the National Science Foundation (NSF), National Institutes of Standards and Technology (NIST), and the University of Hawaii to advance our understanding of NEOs and develop new technologies for their detection and tracking.

History

The NASA Near-Earth Object Program was established in 1998, following a United States Congress directive to NASA to identify and track NEOs that could pose a threat to Earth. The program has since worked closely with the National Aeronautics and Space Administration Authorization Act of 2005, the George E. Brown, Jr. Near-Earth Object Survey Act, and the Planetary Science Decadal Survey to develop a comprehensive strategy for detecting and tracking NEOs. The program has also collaborated with the European Space Agency (ESA) on the Space Situational Awareness (SSA) program and with the Japan Aerospace Exploration Agency (JAXA) on the Hayabusa2 mission to advance our understanding of NEOs and develop new technologies for their detection and tracking. Key milestones in the program's history include the discovery of Asteroid 101955 Bennu by the University of Arizona and the Lincoln Near-Earth Asteroid Research (LINEAR) project, as well as the successful landing of the OSIRIS-REx spacecraft on Asteroid 101955 Bennu.

Objectives and Responsibilities

The primary objectives of the NASA Near-Earth Object Program are to detect, track, and characterize NEOs that could potentially impact Earth, and to develop strategies for their deflection and disruption. The program is responsible for coordinating with international partners like the European Space Agency (ESA), Canadian Space Agency (CSA), and the Japan Aerospace Exploration Agency (JAXA) to share resources and expertise. The program also works closely with the Federal Emergency Management Agency (FEMA), National Oceanic and Atmospheric Administration (NOAA), and the United States Air Force (USAF) to develop response plans in the event of a predicted impact. By leveraging the capabilities of Telescopes like the Pan-STARRS and Catalina Sky Survey, the program aims to identify potential threats to Earth and develop strategies for their mitigation. The program also collaborates with the National Science Foundation (NSF), National Institutes of Standards and Technology (NIST), and the University of Hawaii to advance our understanding of NEOs and develop new technologies for their detection and tracking.

Detection and Tracking

The NASA Near-Earth Object Program utilizes a range of detection and tracking techniques, including Asteroid Surveys like the Catalina Sky Survey and the Pan-STARRS survey, as well as Radar Astronomy and Infrared Astronomy techniques. The program works closely with the Minor Planet Center (MPC) and the International Astronomical Union (IAU) to ensure accurate and timely tracking of NEOs. By leveraging the capabilities of Telescopes like the Hubble Space Telescope and the Spitzer Space Telescope, the program is able to accurately predict the orbits of NEOs and assess their potential threat to Earth. The program also collaborates with the European Space Agency (ESA) on the Space Situational Awareness (SSA) program and with the Japan Aerospace Exploration Agency (JAXA) on the Hayabusa2 mission to advance our understanding of NEOs and develop new technologies for their detection and tracking.

Deflection and Disruption Methods

The NASA Near-Earth Object Program is exploring a range of deflection and disruption methods, including Kinetic Impactors like the DART mission, Gravity Tractors like the Keck Observatory, and Solar Sails like the Planetary Society's LightSail 2 mission. The program is also investigating the use of Nuclear Explosives and Laser Ablation techniques to deflect or disrupt NEOs. By collaborating with international partners like the European Space Agency (ESA), Canadian Space Agency (CSA), and the Japan Aerospace Exploration Agency (JAXA), the program aims to develop a comprehensive strategy for deflecting or disrupting NEOs that could pose a threat to Earth. The program also works closely with the Federal Emergency Management Agency (FEMA), National Oceanic and Atmospheric Administration (NOAA), and the United States Air Force (USAF) to develop response plans in the event of a predicted impact.

Notable Discoveries

The NASA Near-Earth Object Program has made several notable discoveries, including the detection of Asteroid 101955 Bennu by the University of Arizona and the Lincoln Near-Earth Asteroid Research (LINEAR) project. The program has also collaborated with the European Space Agency (ESA) on the Rosetta mission to Comet 67P/Churyumov-Gerasimenko and with the Japan Aerospace Exploration Agency (JAXA) on the Hayabusa2 mission to Asteroid 162173 Ryugu. Other notable discoveries include the detection of Asteroid 2011 AG5 by the Catalina Sky Survey and the discovery of Comet C/2013 A1 (Siding Spring) by the Siding Spring Observatory. The program continues to work closely with international partners and the Astronomical Community to advance our understanding of NEOs and develop new technologies for their detection and tracking. The program also collaborates with the National Science Foundation (NSF), National Institutes of Standards and Technology (NIST), and the University of Hawaii to advance our understanding of NEOs and develop new technologies for their detection and tracking.
