Multiple Probe Measurements at Uranus Motivated by Spatial Variability.

Area of Science:

• Planetary Science
• Atmospheric Dynamics
• Planet Formation

Background:

• Uranus's atmospheric spatial variations in thermal structure, composition, and winds are key to understanding its internal processes.
• Understanding these variations is vital for addressing origin questions about Uranus's formation and evolution within the protoplanetary disk.

Purpose of the Study:

• To review current knowledge of spatial variability in Uranus's atmosphere.
• To outline how multiple atmospheric probe missions would enhance understanding of these variations.
• To connect Uranus exploration to lessons learned from multiprobe missions to Jupiter, Saturn, and Neptune.

Main Methods:

• Reviewing existing data on Uranus's atmospheric spatial variability.
• Analyzing the scientific value of multiple probe missions, including miniature secondary probes.
• Examining challenges and uncertainties in mission design, cost, trajectory, instrumentation, power, and timelines.

Main Results:

• Spatial variations in thermal structure indicate atmospheric heat transport mechanisms.
• Compositional variability measurements are essential for determining bulk heavy element abundances.
• Lessons from Jupiter, Saturn, and Neptune highlight the importance of multiprobe exploration for understanding giant planet atmospheres.

Conclusions:

• Multiple atmospheric probes are essential for a comprehensive understanding of Uranus's dynamic processes, composition, and origin.
• Future multiprobe missions, complemented by secondary probes, can overcome current challenges and provide critical data.
• Exploration of Uranus's atmosphere offers insights into the broader context of giant planet formation and evolution.
