Central Texas Chapter

On 19 April, the IEEE Central Texas Chapter hosted a lunchtime presentation by Dr. Mark Tapley of Southwest Research Institute.

Dr. Tapley’s presentation was entitled “Deep Space Communications from Earth to New Horizons Spacecraft.” It was an interesting talk on the technical difficulties of deep space communications from Earth to the New Horizons Spacecraft during its flyby of Pluto in 2015 and Ultima Thule (2014 MU 69) in 2019. Because of the extreme distance of the spacecraft from the Earth (over 43 AU or 4 billion miles), there is a 300 dB loss in signal strength that limits the data transmission rate to 2 kilobits per second.

Dr. Tapley is an Institute Engineer in the Space Science and Engineering Division of Southwest Research Institute. He serves as the Deputy Payload Systems Engineer for the New Horizons mission.
