The SubTEC IV rocket, NASA 41.096GT, was launched from Wallops Island on Jun 10.
It carried a new high data rate X-band telemetry system and the 0.4-meter
SMART microsatellite bus.
Apogee was 188 km according to the Wallops Twitter feed. My impression is that SMART separated from the main payload; it is a GSFC/USAF-ORS payload 0.4m in size, but I haven't been able to find the mass.
