Additional Pluto Flyby Information:

Timing dependent on what happens during downlinks with the Deep Space Network, hence subject to change.
Jimmy Lee from NASA’s Marshall Space Flight Center provided the attached sheet. Below are the details:
- On approach, LORRItakes critical optical navigation images to confirm the spacecraft is on the right course for the flyby. The team can use these data to adjust timing of the observation sequence as late as July 12.
- Final radio transmission prior to closest approach is received at ~11:15pm EDT on July 13.
- During the flyby on July 14, LORRIwill take high-resolution B/W images, Ralph / MVIC will make color maps, and Ralph / LEISA will image the system in the infrared, all of which will help determine the geology and composition of the surface.
- Closest approach to Pluto is at 7:49:57 a.m. EDTon July 14.
- Approximately one hour after closest approach, at 8:51am EDT on July 14, the spacecraft will turn around and, with Pluto between it and the Sun, Alicewill make ultraviolet measurements to determine the composition of the atmosphere.
- When Pluto is between the spacecraft and Earth, REXwill receive transmissions from the Deep Space Network (DSN) to determine the pressure and temperature of the atmosphere.
- The spacecraft will orient toward Earth and make its first transmission after the closest approach at approximately 4:30 pm EDT, which arrives at earth at approximately 9:00 pm EDT.
- Throughout the flyby, SWAPand PEPSSI will characterize the energetic particle environment, and SDC will search for dust in the Pluto system.
