Discussion Overview
The discussion revolves around the potential collision risks faced by the New Horizons probe during its flyby of Pluto, particularly in light of Pluto's moons and the presence of smaller, undetected objects in the vicinity. Participants explore the implications of these risks, the probe's trajectory adjustments, and the capabilities of the spacecraft in capturing images of Pluto and its surroundings.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- Some participants express concern about the possibility of the New Horizons probe colliding with unseen objects, suggesting that the presence of multiple moons indicates a higher likelihood of smaller bodies in the area.
- Others argue that the chances of a collision are astronomically low, particularly with larger objects, and emphasize the difficulty in detecting small objects (1mm to 10cm) at such distances.
- A participant highlights that the probability of hitting one of Pluto's moons is about 1 in 10 million, which they consider negligible compared to other risks in space missions.
- There is speculation about the potential impact of a small object on the mission, with one participant noting that even a dime-sized object could be catastrophic at high speeds.
- Questions are raised regarding the timing and feasibility of capturing images of Pluto before the closest approach, with some suggesting that energy limitations may restrict the probe's capabilities.
- Another participant provides information about the probe's current distance from Pluto compared to Hubble's distance, arguing that Hubble's resolution is currently superior.
- Concerns are mentioned about avoiding Lagrangian spots in the Pluto system and the viability of a ring system around Pluto, with speculation on the effects of Pluto's atmosphere on such a system.
Areas of Agreement / Disagreement
Participants express a mix of concerns and technical insights regarding collision risks, with no consensus on the likelihood of such events or the effectiveness of the probe's imaging capabilities prior to its closest approach.
Contextual Notes
Limitations include the uncertainty surrounding the detection of small objects at great distances and the specific energy constraints of the New Horizons probe, which may affect its operational capabilities.
