Questions & Answers

Q: What is the purpose of the Cygnus mission?

The primary goal of the mission is to study hurricanes and gain a better understanding of their intensity and growth. By measuring surface winds using reflected GPS signals, Cygnus will provide valuable information about the dynamic energy within hurricanes.

Q: How does Cygnus differ from other missions studying hurricanes?

Unlike other missions, Cygnus will be able to see through rain using its unique frequency. This ability allows Cygnus to provide data about areas where it's raining, which is crucial for understanding hurricane dynamics.

Q: What is the lifespan of the eight Cygnus satellites?

The baseline mission for the satellites is two years. However, each satellite is built to last five years or more. The decision to continue operational the satellites beyond the baseline mission will be based on their performance and scientific value.

Q: Why was the Pegasus launch vehicle chosen for this mission?

Pegasus was chosen for its low cost and capability to launch smaller payloads like the Cygnus spacecraft. It offers a flexible and cost-effective solution for launching scientific missions.
