ISS Science for Everyone

Science Objectives for Everyone
Operating space hardware still requires a complicated set of computer software, which operations teams on the ground maintain. The Flight Demonstration of Telescience Resource Kit (Telescience Resource Kit [TReK]) is a software package that simplifies the software running on the International Space Station (ISS), benefiting users on Earth. Eventually, TReK software will allow scientists, engineers and students who conduct experiments in space to connect to their experiments through regular Internet connection protocols using the new and improved onboard Ethernet communications recently added to ISS.

Experiment Description

Research Overview

  • The Flight Demonstration of Telescience Resource Kit (Telescience Resource Kit [TReK]) software is a generic flight software to be provided as a standard capability to future payloads.
  • TReK runs on an ISS provided T61p laptop for its on-orbit demonstration.
  • On-orbit tests are performed to collect benchmark metrics for Ku Forward protocols.
  • Interface to the Network Attach Storage device as the pathfinder payload.
  • Operate for periods during Inc. 48.  Both weeks focus on collecting IP Protocol metrics.

Description
The Flight Demonstration of Telescience Resource Kit (Telescience Resource Kit [TReK]) software is one of the Huntsville Operations Support Center (HOSC) remote operations solutions originally developed to simplify ground software development by hiding complexities of ground interfaces (Payload to Generic User Interface Definition Document) and to provide a low-cost ground operations solution (Windows PC) that is easy to install/configure/run at remote sites. TReK is comprised of a suite of software applications and libraries that provide generic data system capabilities and access to HOSC services. TReK enhancements are underway in to provide a simple solution for payloads to interface with new and improved onboard Ethernet communications. Ku-IP Services is a new capability that essentially “puts the payload on the internet”. Payload developers use standard internet protocols to interface with their payload. Delay Tolerant Networking (DTN) is implemented as well; payload developers have the power to automate end-to-end operations. This increases science return and decrease operations costs. The TReK software not only provides Ku-IP and DTN capabilities, but also simplifies access to these capabilities. TReK is available on Windows 7 and Red Hat Enterprise Linux 6.x. The TReK software is available for use on-board and on the ground to perform common functions needed by most payloads. For example, this includes sending and receiving data, packaging and un-packaging data values, transferring files, managing a DTN node, etc. For its flight demonstration, the TReK software is loaded onto an ISS provided T61p laptop and operates for approximately two weeks with data transfer to collect benchmark metrics.

Applications

Space Applications
The ISS uses high-speed Ethernet communications to talk to the ground and to experimental payloads on board. The Telescience Resource Kit provides support for connecting payloads to the Ethernet, which allows people on the ground to use standard Internet protocols to operate equipment in space. The investigation also implements Delay Tolerant Networking, which enables brief delays in data transmission without interrupting or ending the connection. This increases the amount of data managers can download, benefiting research and lowering costs.

Earth Applications
People who send experiments into space have to use complicated space station hardware and software to communicate with their equipment and get results. Future payload developers will have a much easier interface with the Telescience Resource Kit software, which allows users to communicate with the space station using regular Internet protocols. The TReK software also improves the methods used to transfer data to the ground. Results from the investigation are applicable to ground data-transfer problems, such as power outages or service interruptions that disrupt communications.

Operations

Operational Requirements and Protocols

The TReK software is a generic flight software capability to be provided as a standard service to future payloads.
 
TReK requires ISS provided T61p laptop.  The on-orbit demonstration collects benchmark metrics, and is used in the future to provide live demonstrations during ISS Payload Conferences.  Benchmark metrics and demonstrations address the protocols for Ku IP Services section.
 
On-orbit tests collect benchmark metrics for Ku IP protocols.  Two Sessions – each 1 week in duration; ground operations conducted from 8 am to 5 pm central time daily during standard work week. Session 1 and Session 2 are to be separated by  in order to allow for benchmark data analysis.
 
 

The Telescience Resource Kit flight software is loaded on an ISS provided T61p computer and interfaces with the onboard Ethernet Local Area Network. The crew sets up the computer and uses the new ISS Payload Network Address Storage PXE Boot capability to load the software. The benchmark testing is performed by the Payload Developer during scheduled command windows.
