Motivation! Development of the CubeSat standard has enabled a vibrant new ecosystem
of nanosatellite development and missions ! Predicated on “ride along” opportunities ! Very low cost to orbit ! Greater tolerance for risk ! Simple integration with launch vehicle
! Started with universities, now adopted by global community including government, industry, and private individuals
! Commercial supply chain has developed & matured ! Many components available off the shelf ! Further enables cost reduction, speeds development time
How can we replicate and leverage the CubeSat standard for airborne payloads?

XCube, CubeSat, what is the difference ?
XCubes are U-Class experiments (they use the same form factor as CubeSats) They are designed to fly inside a Host vehicle (Aircraft, Balloon, Rocket, Spacecraft)
XCubes can be independent, but typically would use the power supply and communication system provided by the Host

InnovationUnique advantages include:
• Modular – Easy to manufacture using rapid prototyping equipment.
• Will make collaboration much simpler by providing a standard for experiments based on the well-established Cubesat form factor and interface.
• It will also help researchers by providing cost effective access to NASA flying vehicles.
• The use of Cubesat form factor and the use of rapid prototyping to design Pods and payloads, compatible with widely available commercial CubeSat boards

XCube advantages
! Based on CubeSat: Well-known standard with large, supportive community
! Experimenters can take advantage of CubeSat COTS components to reduce development time and cost
! Allows experimenters to develop payload in the lab, with easy integration for flight
! Provides easy, standardized access to broad range of flight environments (low to high, slow to fast, short to long)
! Same path leads to orbit
