What is orientation of a needle shaped spacecraft?

Click For Summary
SUMMARY

The discussion centers on the orientation of a needle-shaped spacecraft as it approaches a neutron star with a radius of 10 km and a mass 1.5 times that of the Sun. It concludes that the spacecraft's most likely orientation at its closest approach of 20 km from the center of the star is radial towards the star due to tidal forces, which create a significant difference in gravitational acceleration between the tip and tail of the spacecraft. The conversation emphasizes that the tidally locked state is the most probable configuration for gravitational systems, particularly during close encounters with massive celestial bodies.

PREREQUISITES
  • Understanding of tidal forces and their effects on spacecraft orientation
  • Familiarity with gravitational potential energy concepts
  • Knowledge of the characteristics of neutron stars
  • Basic principles of orbital mechanics and angular momentum
NEXT STEPS
  • Research the effects of tidal forces on spacecraft during close approaches to massive objects
  • Study the concept of tidally locked states in gravitational systems
  • Explore the gravitational dynamics of neutron stars and their influence on nearby objects
  • Learn about the mathematical modeling of gravitational interactions in orbital mechanics
USEFUL FOR

Astronomers, astrophysicists, aerospace engineers, and anyone interested in the dynamics of spacecraft navigation near massive celestial bodies.

I just wish that the problem was stated more clearly

Yes, that was also my first thought.

but rather a direct hit with the spacecraft headed toward the COM of the star.

In this case I would expect the word "impact" instead of "closes approach". But you are right, this is a possible interpretation.
