Following deployment from the Artemis launch adaptor, contact with the spacecraft showed that it successfully stabilized and deployed its solar arrays, but after the initial 57 minute 27 second radio contact, no further contact was established, however the search is still on. Blind commanding will be performed to stabilize the spacecraft should it still be functioning. [5] No contact has been established as of September 25, 2023 and NASA will not fund further attempts at contact.
Objective
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 12:47 am ET, The Orion/ICPS performed a Trans-Lunar Injection and separated.
Shortly thereafter, CuSP was deployed from its launch canister.
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 stopped suddenly 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, and no further contact has yet been 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.
The CuSP team fully investigated an anomalous high IRIS Radio temperature and found it to only be a GSE scaling problem.
Additional contact attempts are planned during the third quarter of 2023.
