The Jet Propulsion Laboratory has implemented the Radiometer Atmospheric CubeSat Experiment (RACE) as an opportunity for early career hires to develop their technical, leadership, and flight project skills through the Phaeton Program.
The primary scientific expedition of RACE is to measure the liquid water path and precipitable water vapor that is pertinent to the water cycle and Earth energy budget. The RACE payload is a microwave radiometer that primarily observes the 183 GHz water vapor line.
RACE will advance the technology readiness level (TRL) of the receiver subsystem from TRL 4 to TRL 6 and the CubeSat radiometer system from TRL 4 to TRL 7. The radiometer is designed to fit within a 1.5 U volume (10x10x15 cm3) such that any CubeSat platform with a larger volume (2U, 3U, or 6U) can be used. CubeSats are usually secondary payloads to missions but are considerably cheaper to launch, which allows for technology risk reduction and fulfills NASA's CubeSat Launch Initiative (CSLI). A radiometer within the CubeSat platform has the potential to revolutionize systems by moving from the traditional large scale missions (which often have significant technical risks and costs) to distributed smaller missions.
RACE will assist in developing and demonstrating critical technologies that will improve NASA's exploration, science, and discovery mission objectives (NASA Science Mission Directorate).
To advance the technology of the 35 nm indium phosphide (InP) receiver subsystem of the radiometer instrument.
To enhance the hands-on training for the RACE project team members within the Phaeton Program platform.
To reduce the risk for future users of the technology explored through RACE.
To advance the technology of the water vapor radiometer CubeSat system.
To explore possibilities for smaller missions with distributed risks.
Water vapor is important on a global scale as it helps us understand the water cycle, which is turn is a crucial component of the Earth's energy balancing system. Understanding and monitoring of water vapor will help in the understanding of both weather and climate processes (both near and long term impacts). Specifically, 183 GHz is useful as a water vapor line as we are able to profile different layers of the atmosphere with multiple channels, this allow us to investigate the flow between regions, both vertically and horizontally. The higher frequency also allows for smaller components, especially with regards to the antenna aperture which affords smaller footprints/pixels on the ground, which is crucial as water vapor features tend to vary on small spatial scales. The technology proposed is cutting edge which will improve the performance of future instruments developed. Further, utilizing CubeSats allows for cheaper missions, which is increasingly important with limited science budgets.
The key to the instrument development is the low noise amplifier (LNA) in the receiver. The LNA utilizes the 35 nm Indium Phosphide (InP) High Electron Mobility Transistors (HEMT) process developed by Northrop Grumman Aerospace Systems (NGAS). JPL is a leader in developing low power and low noise figure 183 GHz receivers stemming from substantial NASA Earth Science Technology (ESTO) investments.
CubeSats cube-shaped nanosatellites built on 10x10x10 cm units, termed 1U. RACE will be a 3U CubeSat, that is 30x10x10 cm. The concept of CubeSats originated in academia to provide a means for university students to perform space science and exploration at low cost. After numerous successful launches and demonstrations of CubeSats, interest in these low risk, low cost, and quick turnaround missions has increased at JPL and NASA.
The Texas Spacecraft Laboratory (TSL) at the University of Texas at Austin is designing, building, and testing and the CubeSat for the RACE mission. The RACE radiometer is designed to fit within a 1.5 U volume (10cm x 10cm x 15cm). TSL was the winner of the University Nanosatellite Program 7 in the CubeSat class.
