OSIRIS-REx Spacecraft
Host
The sub-systems that comprise the OSIRIS-REx spacecraft are the telecommunications subsystem; the power sub-system; the propulsion sub-system; and the guidance, navigation, control (GNC) sub-system. These sub-systems work together to communicate with the Earth, deliver the spacecraft to the target asteroid, and navigate around the asteroid. The spacecraft hosts a navigation camera system (TAGCAMS), a science camera system (OCAMS), a visible and infrared spectrometer (OVIRS), a thermal emission spectrometer (OTES), and a laser altimeter (OLA). The collection, retrieval, storage and return of the asteroid sample is conducted using the Touch-And-Go Sample Acquisition System (TAGSAM), and the Sample Return Capsule (SRC). The combined spacecraft sub-systems and the hosted complement of instrumentation allows the OSIRIS-REx mission to gather data, collect a sample, and safely return the sample to Earth.

OSIRIS-REx Radio Science (Telecom) Subsystem
Instrument
The spacecraft element of the OSIRIS-REx radio science instrument was the
onboard telecommunications subsystem. It included a pair of cross-strapped redundant
General Dynamics Small Deep Space Transponder Group Buy III X/X transponders, two cross-strapped 100-watt traveling wave tube
amplifiers, and four antennas. Cross-strapping protected the mission against single point failures in the telecom subsystem.

NASA Deep Space Network Radio Science
Instrument
Radio science and radio tracking instrumentation at the NASA Deep Space Network (DSN)
utilize capabilities of the DSN in combination with telecommunications equipment
on board spacecraft to make measurements that can be used to study gravity fields,
relativistic effects, and the properties of plasmas, and planetary surfaces, atmospheres,
ionospheres, and rings throughout the solar system. The DSN also sends commands to
spacecraft and receives telemetry from them. This equipment may also be used for
reception only, such as for radio astronomy observations of natural sources and
for very long baseline interferometry. With few exceptions, this instrumentation
is available for connection to any DSN antenna. Performance then depends on antenna size,
wavelength, transmitter and low-noise amplifier selected, and local observing conditions.
The instrumentation has evolved over time since the DSN was established in the 1960s.
