Following deployment from the Artemis launch adaptor, contact with the spacecraft showed that it successfully stabilized and deployed its solar arrays, but contact was long after about an hour.[5]
Measuring space weather that can create a wide variety of effects at Earth, from interfering with radio communications to tripping up satellite electronics to creating electric currents in power grids, is of importance. To create a network of space weather stations would require many instruments scattered throughout space millions of miles apart, but the cost of such a system is prohibitive.[2] Though the CubeSats can only carry a few instruments, they are relatively inexpensive to launch because of their small mass and standardized design. Thus, CuSP also was intended as a test for creating a network of space science stations.[2]
Miniaturized Electron and Proton Telescope (MERiT), is built by the NASA's Goddard Space Flight Center and will return counts of high-energy solar energetic particles.
Vector Helium Magnetometer (VHM), being built by NASA's Jet Propulsion Laboratory, will measure the strength and direction of magnetic fields.
After a successful launch of the SLS at 1:47 am EST on November 16 2022, The Orion/ICPS performed a Trans-Lunar Injection and separated.
Shortly thereafter, CuSP was deployed from its launch canister in the ICPS.
Twenty-three minutes after deployment, DSN received Open Loop Receiver (OLR) telemetry from CuSP indicated it had booted up, detumbled, deployed solar arrays, and assumed a SAFE, Sun-pointing, orientation.
It was operating perfectly until...
OLR monitoring of the radio signal indicated that the transmitter carrier signal vanished after transmitting for 1 hour and 15 minutes.
No cause has been determined for this end of transmission.
Multiple attempts to receive additional signals from the spacecraft failed through the end of 2022. No contact was made.
The CuSP team fully investigated a sudden battery temperature increase and found it was a telemetry failure. This was verified by comparing redundant indications of several parameters. The redundant indications did not show the suspected excursion. This failure was proven to be the failure of a temperature monitor which saturated the ADC inputs of several signals, but not their redundant monitors fed to an independent ADC.
The CuSP team fully investigated an anomalous high IRIS Radio temperature. JPL IRIS engineers traced it to a failure to update a scaling equation in the SMOC EGSE. Once the updated equation was applied, the temperature fell in line with all others.
Plans were to make another attempt during an expected focal convergence, however, no further contact attempts were made to contact the spacecraft.
Official End Of Mission was declared December 2023.
