> China launches new batch of Yaogan reconnaissance satellites
> HELSINKI — China added to its recent flurry of reconnaissance satellite launches early Sunday, sending three new Yaogan-39 spacecraft into orbit.
> A hypergolic Long March 2D rocket lifted off at 12:13 a.m. Eastern (0413 UTC) Sept. 17, rising into overcast skies above the Xichang Satellite Launch Center in southwest China.
> Four objects from the launch were tracked in roughly circular 495-kilometer-altitude orbits inclined by 35 degrees.
> Yaogan satellites are thought to variously carry optical, synthetic aperture radar (SAR) and other sensors. Some satellites are described generically as being for “electromagnetic environment detection and related technical tests.” This may indicate the satellites are for electronic intelligence gathering.

> L3Harris exploring supplier partnerships for its satellite business
> Space sector president Kelle Wendling: ‘We’re talking to all bus suppliers’
> L3Harris produces satellites in Melbourne, Florida, not far from where Blue Origin is building hardware for its New Glenn rocket.
> “We’re interested in some of their capabilities,” said Wendling, such as a payload ring adapter that Blue Origin designed to carry small satellites to orbit as secondary payloads — similar to the ESPA rings that are used on large rockets today.
