We’ve Made Contact with STEREO B!
On Aug. 21, 2016, NASA reestablished contact with the spacecraft,
after communications were lost in October 2014.
STEREO consists of
two nearly identical
spacecraft put into
slightly different orbits
around the sun – one
moving faster than
Earth, one moving
more slowly.
In December 2015, the
lines of communication
to both STEREO
spacecraft—Ahead in
red and Behind in
blue—were far enough
from the sun that
mission operators could
send signals to both
spacecraft. STEREO-A
is in communication
and operating normally,
and mission operators
resumed attempts to
contact STEREO-B.

STEREO B Path Forward
8/22/16
• Need to turn on the Integrated Electronics Module (IEM) in order to get
telemetry down and ascertain the state of the S/C. However, the turn-on of
the IEM/C&DH needs to be managed carefully
1. Not put too much load on the power system, which is likely to be in a fragile/intermittent
state.
• After IEM power up, autonomy would normally start turning components on
2. Not allow the known faulty IMU measurements to be utilized in the Attitude Control
System.
• Strong downlink signal for over 5 hours at multiple DSN stations indicates
the power/attitude situation is not in its worst case condition.
– Function of geometry, which will evolve slowly as STEREO progresses in its heliocentric
orbit and as attitude profile evolves.
• The team has scheduled daily 3 hour contacts on DSN, and will seek
additional 70m time.
It has been 22 months since the initial anomaly. This remarkable
development is a tribute to the engineering team that built the
spacecraft, to the project for their persistence and patience in
possible recovery of the spacecraft, and to the operations team.

Living With A Star
• The Living With a Star (LWS) program emphasizes the
science necessary to understand those aspects of the Sun
and the Earth's space environment that affect life and society.
• Ultimate goal is to provide a predictive understanding of the
system, and specifically of the space weather conditions at Earth
and in the interplanetary medium.
• LWS missions formulated to answer specific science questions
needed to understand the linkages among the interconnected
systems that impact us.
• LWS products impact technology associated with space systems,
communications and navigation, and ground systems such as
power grids.
• The coordinated LWS program includes strategic missions,
targeted research and technology development, a space
environment test bed flight opportunity, and partnerships with
8
other agencies and nations.

ROSES 2017:
• New procedure initiated for development of FSTs
• Mandatory funding in President’s FY17 budget request
“Living with a Star is supported in part with mandatory funding. The
mandatory investment includes $10 million for Living With a Star (LWS)
Science, to accelerate efforts in support of the Administration’s multiagency Space Weather Action Plan. Work will include benchmark
maturation, implementation of FY2016 plans, and continuation of
planning efforts between the agencies. The investment will also
augment Living with a Star Research and Analysis elements that

Living With a Star Target Research and
Technology
The Targeted Research and Technology (TR&T) component of LWS provides
the theory, modeling, and data analysis necessary to enable an integrated,
system-wide picture of Sun-Earth connection science with societal relevance.
Focus Science Topics coordinate large-scale investigations that cross
discipline and technique boundaries leading to an understanding of the
system linking the Sun to the Earth and Solar System.
Strategic Capabilities develop one or more deliverables that address a
significant and specific need for achieving the LWS and NSWP goals;
incorporating the latest scientific results from LWS Focus Science Teams as
well as other research.
LWS Institutes are designed to facilitate a bridge between cutting-edge
heliophysics research and a societally relevant technology area that is
affected by space weather. Working groups will define and scope new
research that will make a critical difference to this technology.

LWS TR&T Background
2003 LWS Science Definition Team Report:
TR&T Program
The Targeted Research and Technology (TR&T) component of LWS provides the theory,
modeling, and data analysis necessary to enable an integrated, system-wide picture of
Sun-Earth connection science with societal relevance.
Science Definition Team (SDT) … formed to design and coordinate a TR&T program
having prioritized goals and objectives that focused on practical societal benefits.
TR&T Steering Committee (TSC), with broad science and application community
representation and with rotating membership, to advise and support NASA Headquarters
in:
• Establishing and continually updating targets and top-level priorities
• Measuring the progress of the program in meeting science goals and objectives
• Providing mechanisms for monitoring how well products that result from the program
29
are transferred into societal benefits.
TR&T Steering Committee Finding
From February 8-9, 2016 Meeting:
“Procedure for Development of Annual TR&T Science

It is vital for the success of the Living with a Star Targeted Research and
Technology (LWS TR&T) program that there be active community
engagement in the development of annual TR&T science topics.
The LWS TR&T Steering Committee (TSC) found that the following procedure
should be followed to solicit and obtain community input for and to then
develop these science topics:
•
•
•
•
Encourage active community input to TR&T science topics
Draft science topics at second TSC meeting
Solicit community comment on draft TR&T science topics
Finalize science topics at third TSC meeting
30
Encourage active community input to TR&T
science topics
•Announce call for community input to science topics through Space Physics
