The first Sherpa-FX will carry 14 spacecraft on <strong>SpaceX<\/strong>\u2019s SXRS-3 mission set for December.&nbsp;<\/p>\n<p>The basic model, a hexagonal Sherpa-FX, has multiple ports that multiple smallsats can attach to. In action, the Sherpa-FX separates from a launch vehicle, and satellite separations are then initiated by onboard avionics. It can execute multiple deployments and provides independent deployment telemetry. This vehicle can deliver satellites to altitude changes or phases of specific orbits, and minor inclination changes.&nbsp;<\/p>\n<p>Beyond the Sherpa-FX, Spaceflight on Thursday announced two Sherpa variations with their own propulsion systems coming in 2021. The Sherpa-LTC\u2019s has a high thrust, bi-propellant, green propulsion subsystem from <b>Benchmark Space Systems<\/b>, and can provide rapid orbital transfer.&nbsp;<\/p>\n<p>And the Sherpa-LTE incorporates an Apollo Constellation Engine (ACE), a low thrust, high efficiency, radiation hardened Hall thruster propulsion system developed by <b>Apollo Fusion, Inc.<\/b> The Sherpa-LTE can deliver customers to Geostationary (GEO), Cislunar, or Earth-escape orbits which Spaceflight said provides a low-cost alternative to purchasing a full direct-inject launch vehicle.&nbsp;<\/p>\n<p>All three are compatible with various launch vehicles from the Falcon 9 to a PSLV, including vehicles in development from <b>Firefly Aerospace<\/b>, <b>Relativity Space<\/b>, <b>ABL Space Systems<\/b>, and <b>Virgin Orbit<\/b>. The orbital transfer vehicles are designed to give satellites the flexibility to move between launches to deal with delays, with minimal impact to the launch provider.&nbsp;<\/p>\n<p>\u201cThis is extending our value proposition of flexibility both for the launch vehicle and for the satellite customers. Our satellite customers can go on any of these ports and go between missions if their satellites are delayed,\u201d Jeff Roberts, senior director of Mission Management explained to <i>Via Satellite<\/i>. \u201cFor the launch vehicle, a Sherpa is a Sherpa. It doesn\u2019t matter what\u2019s on it. It\u2019s a very minimal impact to the launch providers.\u201d&nbsp;<\/p>\n<p>This is the next-generation and a complete redesign of the two original Sherpa vehicles that flew on the SSO-A SmallSat Express mission in December 2018.&nbsp;<\/p>\n<p>Roberts said the company decided to develop the next-generation series to help customers take advantage of SpaceX\u2019s rideshare pricing, announced last year. Spaceflight wanted to allow as many smallsat customers as possible to share one port. If Sherpa were fully loaded with only cubesat deployers on board, for example, it could handle 32 3U cubesats.&nbsp;<\/p>\n<p>The orbital transfer vehicle line is a response to the evolving needs of smallsat customers. Rideshare isn\u2019t good enough for some anymore, he said.&nbsp;&nbsp;<\/p>\n<p>\u201cWe still have our standard rideshare capabilities with numerous launch providers, and we\u2019ll continue to offer those services. For customers that want to optimize use on a single port on SpaceX rideshare, or they need to get to a different orbit than what SpaceX offers, or there\u2019s multiple customers that need different orbits, that would be the value proposition of the Sherpa.\u201d&nbsp;<\/p>\n<p>He gave the example of Starlink missions to mid-inclination. \u201cThe altitude is so low, most customers can\u2019t find it useful. But with Sherpa and putting them on top, now we can boost up to an operational altitude for our customers, since most of our customers\u2019 small satellites don\u2019t have a lot of internal propulsion.\u201d <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Spaceflight is rolling out its next-generation orbital transfer vehicles called the Sherpa series \u2014 a \u201clast mile\u201d delivery service for smallsats on rideshare missions.
