NASA announces the Common Instrument Interface (CII) Project Workshop 1, scheduled for April 21, 2011, in Greenbelt, MD.

The workshop is sponsored by the Earth System Science Pathfinder (ESSP) Program, a space flight program in the Earth Science Division of NASA’s Science Mission Directorate (SMD). The ESSP Program includes a series of relatively low-to-moderate cost, competitively selected, Principal Investigator-led mission and instrument investigations that are built, tested, and launched in a short time interval in order to accommodate new and emergent scientific priorities.

The 2007 Decadal Survey for Earth Science identified the Earth Venture (EV) class of space investigations which could include stand-alone missions that use simple, small instruments, spacecraft, and launch vehicles; more complex instruments of opportunity flown on partner spacecraft and launch vehicles; or complex sets of instruments flown on suitable sub-orbital platforms to address focused sets of scientific questions. Earth Venture investigations focus on establishing new research avenues or on demonstrating key application-oriented measurements. Earth Venture’s key to success is maintaining a steady stream of opportunities for community participation in the development of innovative ideas, which requires that strict schedule and cost guidelines be enforced for the program participants.

One of the categories of Earth venture investigations, EV Instrument investigations (EV-I), comprise instruments of opportunity flown on partner spacecraft and launch vehicles. The first announcement of opportunity for EV-I investigations is planned for later in 2011.

The Common Instrument Interface (CII) Project will define a set of standard interfaces for EV-I and other Mission of Opportunity instruments that can be flown on a variety of platforms (commercial, military, scientific) that have excess volume, mass, and power to accommodate the instrument.

This one-day workshop provides an open forum for spacecraft developers, Earth science researchers, instrument developers, and the CII Team to discuss interface capabilities and instrument needs. This workshop will shape the CII guidelines that define the instrument interfaces. Specific objectives of the workshop are:

* Providing an overview of the CII project and it anticipated products;
* Discussing the trade space of various parameters (mass, power, data etc.) applicable to common Earth Venture and other Earth science instruments and obtaining the feedback from science and technology leaders;
* Reviewing the data and power specifications developed by the CII Working Group;
* Initiating a discussion of the mechanical, thermal, and environmental specifications; and
* Establishing the process of conducting regular communications and potential future workshops.
Final plans for the workshop, including the workshop date, location, and participant capacity, will be posted on the ESSP Homepage at
