The spacecraft is roughly 2.5 meters across and its mass is 465 kg including propellant. Design features include 64 Gbits of redundant solid-state data storage, a 290 m/s propulsion budget, and the capability to transmit data from 32 AU at almost 1 kilobit/second. urn:nasa:pds:context:instrument_host:spacecraft.nh is_instrument_host Radio Science Experiment Instrument REX requires the coordinated use of Earth-based transmitters and the New Horizons receiver. The Earth-based 'Ground Element' is made up of the Deep Space Network (DSN) hardware and operations facilities that support the New Horizons (NH) mission. The 'Flight Element' includes the 2.1 m spacecraft high-gain antenna (HGA) and the NH radio receiver that has a REX-specific signal processing board, which sends its output to spacecraft data storage. urn:nasa:pds:context:instrument:nh.rex is_instrument urn:nasa:pds:context:resource:resource.nh_rex_online has_resource urn:nasa:pds:nh_documents:mission bundle_to_document Document collection for the New Horizons mission. urn:nasa:pds:nh_documents:rex bundle_to_document Document collection for the REX experiment.
