| 180 | 0.0s | Guest | And it's these questions that EZIE is going after |
| 181 | 3.0s | Host | that is very cool. |
| 182 | 4.6s | Host | So I am curious, how will these three individual |
| 183 | 8.3s | Host | spacecraft operate together to collect measurements? |
| 184 | 13.0s | Guest | Yes. Well, I can help answering that a little bit. |
| 185 | 15.7s | Guest | So we have three, a small CubeSat, |
| 186 | 18.5s | Guest | and you are |
| 187 | 18.9s | Guest | about the size of a suitcase, so they are not that big. |
| 188 | 22.0s | Guest | They are following a science orbit. |
| 189 | 24.8s | Guest | Each orbit, it's about 90 minutes. |
| 190 | 27.3s | Guest | So each spacecraft, |
| 191 | 30.4s | Guest | has 16 orbits in 24 hours. |
| 192 | 33.6s | Guest | And we have three spacecraft. |
| 193 | 35.6s | Guest | So we have 48 times that we can make measurements in a day. |
