The Double Asteroid Redirection Test (DART) spacecraft successfully performed the first test of a kinetic impactor for asteroid deflection by impacting Dimorphos, the secondary of near-Earth binary asteroid (65803) Didymos, and changing the orbital period of Dimorphos. A change in orbital period of approximately 7 min was expected if the incident momentum from the DART spacecraft was directly transferred to the asteroid target in a perfectly inelastic collision, but studies of the probable impact conditions and asteroid properties indicated that a considerable momentum enhancement (β) was possible. In the years before impact, we used lightcurve observations to accurately determine the pre-impact orbit parameters of Dimorphos with respect to Didymos.
View Article and Find Full Text PDFWe present lists of asteroid photometry opportunities for objects reaching a favorable apparition and have no or poorly-defined lightcurve parameters. Additional data on these objects will help with shape and spin axis modeling via lightcurve inversion. We also include lists of objects that will or might be radar targets.

View Article and Find Full Text PDFArticle Synopsis
- This text discusses opportunities for capturing photometric data on asteroids that are currently favorable for observation and lack clear lightcurve information.
- The aim is to improve our understanding of the shape and rotation of these asteroids through lightcurve inversion techniques.
- It also highlights specific asteroids that are set for radar observations, suggesting that lightcurves can complement radar data to refine rotations and pole positions.

- The text discusses opportunities for asteroid photometry on objects with unclear lightcurve parameters, aiming to improve shape and spin axis modeling.
- It highlights the importance of collecting additional data to refine these measurements through lightcurve inversion techniques.
- The document also mentions radar observation targets, indicating that lightcurves can help resolve uncertainties in rotation periods that radar data alone may not clarify.
