N1 - Funding Information:
The Investigation Team is conducting light-curve observations, using both guaranteed telescope access supported by the DART project and the standard competitive proposal process, to ensure meeting the DART-1 and DART-2 requirements.
Funding Information:
This work was supported in part by the DART mission, NASA Contract No. NNN06AA01C to JHU/APL. A portion of this work was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration (80NM0018D0004). The LICIACube team acknowledges financial support from Agenzia Spaziale Italiana (ASI contract No. 2019-31-HH.0 CUP F84I190012600). P.M. acknowledges funding support from CNES and the European Union?s Horizon 2020 research and innovation program under grant agreement No. 870377 (project NEO-MAPP). The work by P.P. and P.S. was supported by the Grant Agency of the Czech Republic, grant 20-04431S. Thanks to the reviewers of this manuscript, both the one who remained anonymous and the one who became Paul Abell. Thanks to J? Grier for helping the lead author navigate a pandemic and making some excellent suggestions concerning manuscript issues. We acknowledge the wider contributions of the DART Investigation Team as a whole to the DART Project both up to this point and looking forward. We particularly thank the DART mission systems engineer, Dr. Elena Adams, and all of the team?s engineers, who have worked diligently through a pandemic in order to bring DART to the launch pad.

N2 - The Double Asteroid Redirection Test (DART) is a Planetary Defense mission, designed to demonstrate the kinetic impactor technique on (65803) Didymos I Dimorphos, the secondary of the (65803) Didymos system. DART has four level 1 requirements to meet in order to declare mission success: (1) impact Dimorphos between 2022 September 25 and October 2, (2) cause at least a 73 s change in its binary orbit period via the impact, (3) measure the change in binary period to an uncertainty of 7.3 s or less, and (4) measure the momentum transfer efficiency (β) of the impact and characterize the resulting effects of the impact. The data necessary to achieve these requirements will be obtained and analyzed by the DART Investigation Team. We discuss the rationales for the data to be gathered, the analyses to be undertaken, and how mission success will be achieved.
