Maxar Technologies’ DigitalGlobe Selects SpaceX to Launch its Next-generation WorldView Legion Satellites

The initial block of the multi-satellite WorldView Legion constellation will be launched by two flight-proven Falcon 9 rockets in 2021.

If this is like many other recently designed constellations it could be one launch each from Florida and California?

[SSL 2017-07-06] SSL To Provide Next-Generation Imaging Satellite Constellation to DigitalGlobe
Quote
PALO ALTO, Calif. – MacDonald, Dettwiler and Associates Ltd. (“MDA” or the “Company”) (TSX:MDA), a global communications and information company, today announced that its subsidiary Space Systems Loral (SSL) was selected to provide a next-generation satellite constellation for high-resolution Earth imaging to DigitalGlobe, the global leader in Earth imagery and information about our changing planet. Called WorldView Legion, the Low Earth Orbit (LEO) satellites will more than double DigitalGlobe’s high-resolution capacity in important regions. The contract is valued at several hundred million U.S. dollars..

[Raytheon] DigitalGlobe selects Raytheon as satellite imaging payload provider for WorldView Legion constellation
Quote
EL SEGUNDO, Calif., Oct. 10, 2017 /PRNewswire/ -- Raytheon Company (NYSE: RTN) was recently selected by DigitalGlobe, Inc. as the next-generation WorldView Legion satellite imaging constellation payload provider. Under the contract, Raytheon will deliver the telescopes, detectors and combined electronics to Space Systems Loral, the WorldView Legion space vehicle integrator.

Raytheon's new payload doubles DigitalGlobe's capacity to capture multispectral and 30 cm imagery, while tripling to quadrupling the company's capacity to image high-demand areas. Once the WorldView Legion constellation is on orbit, DigitalGlobe's combined constellation will be able to image the most rapidly changing areas on Earth every 20 to 30 minutes, from sunup to sundown. WorldView Legion will begin launching in 2020.

AncientU missed the best part! ;D Should come as no surprise in the 2020 time frame, but still great to hear.

"SpaceX is proud to partner with DigitalGlobe to launch the WorldView Legion constellation," said Gwynne Shotwell, President and COO of SpaceX. "We appreciate DigitalGlobe selecting two flight-proven Falcon 9’s to reliably deliver their satellites to orbit.”

Does anyone has info, how many WorldView-Legion satellites are on one Falcon-9 launch?

40 revisits in 24 hours for certain locations would fit well with 6 satellites in an average SSO, I think. Based on the phrasing of the PR and the lowish orbit, I'd bet on 3 satellites per launch. Probably wrong :D

They're not all in SSO, and the revisit rate is for their combined constellation, not just Legion.

[Spaceflight Now] DigitalGlobe books two launches with SpaceX for Earth-imaging fleet

Turner Brinton, a DigitalGlobe spokesperson, said the WorldView Legion satellites will be the primary payloads on each of the Falcon 9 flights in 2021. But he said the company is open to making the rocket’s excess lift capability available for rideshares, or secondary satellites.
