PUNCH consists of four satellites orbiting each other in a constellation.
The suitcase-sized instruments together comprise one, 8,000-mile-wide (12,900-kilometer-wide) space weather detector.
After spending a few weeks getting their gear sorted, all four satellites have now opened their imaging doors.

Were excited to finish on-orbit commissioning and get these cameras working together.
But thats not all, folks.
PUNCHs rocket engines are the size of shot glasses and water-powered.
That safety and stability are worth it even though the thrusters are more complex than conventional hydrazine rockets.
This is merely the preamble to PUNCHs big show.
The spacecrafts are currently undergoing a 90-day commissioning period, and the science mission wont begin until June.
PUNCH will help researchers stay prepared for solar windand solar stormsthat blow energetic particles at our planet.
