Mission brief

What is happening

SpaceX is launching CHORUS on a Falcon 9 Block 5 from Unknown Pad at Cape Canaveral SFS, FL, USA. It is an Earth observation mission heading to Low Earth Orbit.

Why it matters

Earth observation satellites feed weather forecasting, climate records and disaster response, so their data outlives the launch by decades.

Destination: Low Earth Orbit
Payload: CHORUS
Mission type: Earth Science
Rocket: Falcon 9 Block 5
Provider: SpaceX
Launch site: Unknown Pad

CHORUS is MDA's next generation Earth observation constellation, consisting of 2 radar satellites (C-band SAR and X-band SAR), in a 53.5 degree 600 km altitude LEO, with the X-band trailing the C-band by 60 minutes. A collaborative multi-sensor constellation, CHORUS will bring together diverse and unique imagery and data sources and provide a new level of near real-time insight and innovative Earth observation services. Operating in a unique mid-inclination orbit, CHORUS will be able to image day or night, regardless of weather conditions, with daily access of up to 95% of the coverage area. From an industry-leading 700km-wide imaging swath down to sub-metre high resolution, CHORUS will provide the most extensive and unrivalled Earth observation radar imaging capacity available on the market in a single mission.
