Orbit Determination and Nongravitational Effect Characterization for Emirates Mission Targets (10253) Westerwald and (13294) Rockox

Detecting the Yarkovsky effect on kilometer-scale main-belt asteroids remains challenging, yet it directly affects impact-hazard assessment and spacecraft navigation. Ahead of the Emirates Mission to the Asteroid Belt (EMA) flybys of (10253) Westerwald (2030) and (13294) Rockox (2031), we determine precise orbits for b...

Improved ephemerides for major targets of the Emirates Mission to the asteroid belt from multi-source astrometry

Precise orbit determination of main-belt asteroids is essential for deep-space mission design, navigation, and target characterization. This study presents a refined orbit-determination analysis for 623 Chimaera and 269 Justitia, the two largest targets of the Emirates Mission to the Asteroid Belt (EMA). The dynamical...
