The TRMM satellite orbited Earth between 35 degrees north latitude and 35 degrees south latitude, so the original LIS could observe only the planet’s tropical regions. The space station, however, has a higher orbital inclination and therefore provides a vantage point that will allow the LIS to observe areas closer to the poles in the Northern and Southern hemispheres, NASA officials said. Now, the LIS will be able to sample lightning in a broader area from 56 degrees North and 56 degrees South.

The LIS is riding in the trunk of the Dragon cargo craft alongside the SAGE III device. The station’s robotic arms will take the two instruments from the Dragon and will mount them to outside of the International Space Station.
