MESSENGER team is using the CCSDS File Delivery Protocol (CFDP), a highly
specialized protocol designed to overcome space operations communications
challenges, to download data captured during a successful flyby of Earth last
week. <o:p></o:p></span></font></p>
<p class=wwwbodytxt style='margin:0in;margin-bottom:.0001pt;text-indent:.5in'><font
size=2 color=black face=Arial><span style='font-size:10.0pt'>A team of international
space data communications experts, collaborating through the Consultative
Committee for Space Data Systems (CCSDS), developed CFDP to reliably and
efficiently downlink files from a spacecraft even in the strenuous environment
of deep space. Since the MESSENGER spacecraft’s launch a year ago, it
has successfully used CFDP to enable mission communications and will use it
throughout its 7.9-billion kilometer journey to Mercury. <o:p></o:p></span></font></p>
<p class=wwwbodytxt style='margin:0in;margin-bottom:.0001pt;text-indent:.5in'><font
size=2 color=black face=Arial><span style='font-size:10.0pt'>In using CFDP, MESSENGER
communications represents a change in the standard method of storing science
and housekeeping data on spacecraft built by the Johns Hopkins University
Applied Physics Laboratory (JHU/APL). MESSENGER is also the first <st1:country-region
w:st="on"><st1:place w:st="on">U.S.</st1:place></st1:country-region> space
flight mission to use CFDP in mission operations.<o:p></o:p></span></font></p>
<p class=MsoNormal style='text-indent:.5in'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'>Prior to MESSENGER, JHU/APL missions
used a raw storage model of storing data, but new mission and operational requirements
meant that MESSENGER would have to incorporate a file system of data storage into
its spacecraft software architecture. A reliable method of downlinking files
to the ground had to be found and CFDP was chosen by mission planners to do the
job. <o:p></o:p></span></font></p>
<p class=MsoNormal style='text-indent:.5in'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'>CFDP is included in the MESSENGER software
architecture through a reuse of a NASA Jet Propulsion Lab (NASA JPL)
implementation on the ground and a JHU/APL “CFDP-lite”
implementation on the flight side. The NASA JPL implementation is also
used on NASA’s highly successful Deep Impact mission.<o:p></o:p></span></font></p>
<p class=MsoNormal style='text-indent:.5in'><strong><b><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial;font-weight:normal'>“JHU/APL
engineers integrated CFDP software developed by NASA JPL into the MESSENGER
mission's ground system, which communicates with a CFDP flight software implementation
developed by JHU/APL on the spacecraft,” said Christopher Krupiarz, </span></font></b></strong><font
size=2 face=Arial><span style='font-size:10.0pt;font-family:Arial'>senior
professional staff member, JHU/APL Space Department Embedded Systems Group in
Laurel, Maryland (USA). <strong><b><font face=Arial><span
style='font-family:Arial;font-weight:normal'>“Being able to use an international
standard like CFDP was a key factor in getting two systems developed by two
different organizations to work for one Mercury bound spacecraft.”<o:p></o:p></span></font></b></strong></span></font></p>
<p class=MsoNormal style='text-indent:.5in'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'>CFDP is designed to function
reliably despite the long data propagation delays and frequent, lengthy
interruptions in connectivity found in deep space. It uses powerful
forward error correction coding that minimizes data loss in communication
across deep space, and also supports optional “acknowledged” modes
of operation in which data loss is automatically detected and a retransmission
of the lost data is automatically requested. <o:p></o:p></span></font></p>
<p class=MsoNormal style='text-indent:.5in'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'>Some of the world’s leading
space communications experts working within CCSDS collaborated at bi-annual
working group sessions (similar to those scheduled to take place next month in
Atlanta, Georgia) to first standardize CFDP. They defined the protocol
according to space file transfer requirements articulated by CCSDS
participating space agencies, including NASA, the European Space Agency (ESA), the
British National Space Centre (BNSC), the <font color=black><span
style='color:black'>Centre</span> National d'Etudes Spatiales</font> (CNES) and
the Japan Aerospace Exploration Agency (JAXA). The protocol’s ability to
maintain a high level of data transfer reliability even across interplanetary
distances makes it critical to successful communications on deep space missions
like the MESSENGER mission to Mercury and is expected to have a high level of
applicability to future Lunar exploration missions.<o:p></o:p></span></font></p>
<p class=MsoNormal style='text-indent:.5in'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'>CFDP also benefits space flight
missions in another important way: cost savings. <o:p></o:p></span></font></p>
<p class=MsoNormal style='text-indent:.5in'><font size=2 face=Arial><span
style='font-size:10.0pt;font-family:Arial'>CFDP allows an instrument to record
an observation in a file and transmit the file to Earth without having to
consider whether or not physical transmission is possible at that time.
Sequestering outbound data management and transmission planning functions
within CFDP can simplify flight and ground software, which reduces mission
costs - an important benefit to lower cost missions like MESSENGER. <o:p></o:p></span></font></p>
<p class=MsoNormal style='text-indent:.5in;text-autospace:none'><font size=2
color=black face=Arial><span style='font-size:10.0pt;font-family:Arial;
color:black'>CCSDS will continue to foster global scale technical cooperation to
develop recommendations for space communication like CFDP that increase
interoperability, as well as reduce risk and mission operation costs.
Currently, the organization is investigating extending the use of CFDP in
emerging delay-tolerant networking technology to Interplanetary Internet
operations, and specifically to the use of CFDP in complex mission
configurations, which should further enhance the usefulness and value of CFDP to
space exploration missions in the future.<o:p></o:p></span></font></p>
<p class=MsoNormal style='text-indent:.5in;text-autospace:none'><font size=2

CCSDS working group chair and lead CFDP system engineer at NASA JPL in

fabric that can support deep space science and exploration the way the Internet
