Questions & Answers

Q: What are the key technical challenges in developing a Solar Gravitational Lens mission?

The main challenges are power generation, communication, and ensuring longevity of equipment over a 25-year mission duration.

Q: How will the spacecraft achieve autonomy for operations in the focal region?

The spacecraft will need to operate autonomously as umbilical communication from Earth won't be possible, requiring reliable onboard systems.

Q: How will the spacecraft navigate and maintain alignment with the exoplanet for imaging?

The spacecraft will establish a local reference frame using amplified light from the host star and continuously monitor its position in relation to the optical axis.

Q: How will power generation be maintained over the 25-year mission duration?

The mission includes innovative technologies such as distributed power sources and radiation-hardened batteries to ensure power availability throughout the mission.
