Adapter/Fairing Availability

♦ Universal Stage Adapter offers opportunity for co-manifested payloads with Orion spacecraft or near-term 8.4-meter lower- height accommodations.

♦ Universal Stage Adapter accommodations available as soon as 2021

♦ 8.4- and 10-meter fairings available in the mid- and late-2020s, respectively.

SLS Payload Attach Fitting (PAF) provides Secondary Payload accommodations

• Block 1B vehicle offers up to seven 12U to 27U payload locations (or their volume equivalent) on the PAF outer face

• Payloads will be “off” from roll-out through Orion separation and payload deployment

• Payload Deployment System Sequencer; payload deployment will begin with pre-loaded sequence following Orion separation and Upper Stage disposal burn

• Payload requirements captured in a Interface Definition and Requirements Document

www.nasa.gov/sls One Launch, Multiple Disciplines

The first SLS launch will carry 13 6U smallsats, representing Sun multiple disciplines and partners. The smallsats will be deployed • CuSP (Southwest from the Orion Stage Adapter. Research Institute)
