### Ulysses Science Working Team Meeting No. 51, ESTEC, Noordwijk, 22-23 April 2004

### Co-Chairmen: R.G. Marsden / E.J. Smith

Agenda: See Attachment 1

Participants: See Appendix A

Action Items SWT-51 See Appendix B

Action Items SWT-50 See Appendix C

#### Introduction and Welcome

[R. Marsden]{.underline} opened the meeting at 09:30 hrs on Thursday 22
April. The Minutes of SWT-50 were approved with no additions or
corrections. Action Items assigned at SWT-50 (Appendix C) were reviewed.
The first (E. Massey to provide DSN Right Ascension plots to PIs) was
closed, and the second (concerning GRB "on" time during the Swift
payload checkout) was covered as part of the SWT-51 agenda item on
Science Priorities. The agenda for SWT-51 (Attachment 1) was reviewed
and adopted without additions.

#### 

#### NASA Project Manager's Report

[E. Massey]{.underline} presented the status report from the JPL project
office (Attachment 2). Concerning the availability of DSN coverage for
Ulysses during the period 2004-2006, Massey noted that competition will
increase in 2005/2006 as a result of Ulysses moving into a more crowded
area of the sky (see RA charts in Attachment 2). Reporting on the status
of IMP-8, Massey noted that all the supported instruments are operating
nominally, and that data reduction at Kansas is up to date. Highlights
from GALEX, the Spitzer Space telescope (SIRTF), Stardust, Cassini, and
the Mars Exploration Rovers were presented. Upcoming events include the
Ulysses ecliptic crossing on 14 July, and the Genesis sample return on 8
September.

#### NASA Outreach Activities

[A. Angrum]{.underline} presented an overview of Ulysses-related
outreach activities at JPL (Attachment 3). The Ulysses web pages at JPL
have been given a new look and feel, and a dedicated Jupiter Distant
Encounter page has been added. Recent Ulysses web stories included the
"Cold Peril" story initiated by the S/C Operations Team and written by
Tony Phillips, and the ESA SciTech stories written by R. Marsden. New
outreach products include a new Ulysses poster focusing on the Maunder
Minimum and including biographies of selected Ulysses team members, and
Ulysses bookmark.

[S. Suess]{.underline} reported on Ulysses outreach activities at MSFC
(Attachment 4). He urged the SWT to work together with himself and Tony
Phillips to produce more Ulysses-related stories for the
science.nasa.gov website, and asked that future ESA web releases be done
in coordination. Suess also reminded the SWT about the upcoming JDE
session at the Spring AGU meeting in Montreal, and noted that he would
be giving a Ulysses presentation at a Venus transit event in Huntsville.

#### ESA Mission Manager's Report

[R. Marsden]{.underline} presented the status of the ESA project
(Attachment 5). The major news was the approval by the Science Programme
Committee (SPC) of the funding request to continue spacecraft operations
until the end of March 2008, and to support data archiving until
December 2009. Marsden also noted that he had started the process on the
ESA side to obtain an extension of the Memorandum of Understanding
between ESA and NASA. The present MOU terminates in December 2004. Two
successful launches had occurred since the last SWT: Double Star on 29
December 2003, and Rosetta on 2 March 2004. Marsden gave a short status
report on the Solar Orbiter mission assessment activities.

#### Ulysses Book Proposal

[R. Marsden]{.underline} informed the SWT that an invitation had been
received from Springer-Praxis (the publisher of the book "The
Heliosphere Near Solar Minimum") to write a follow-up volume focusing on
the results from the Ulysses Solar Maximum mission (Attachment 6). A
discussion followed in which the SWT was asked for its opinion on the
proposal. There was general interest in the production of a second
Ulysses book, although opinions differed regarding the focus that the
book should have. Rather than a book specifically on the Ulysses
findings at solar maximum, it was felt that a volume with the
heliosphere in a broader context would be preferable. An **Action Item**
(AI-1) was assigned to the PI teams to provide written input on the book
proposal to the Project Scientists and to A. Balogh (to whom the Praxis
invitation was addressed).

#### Missions Operations Manager's Report

[P. Beech]{.underline} presented the MOM report (Attachment 7), noting
that operations had been running smoothly and that data recovery targets
had been maintained and even exceeded during the reporting period.
Ground segment performance had been excellent. Data recovery during the
Jupiter Distant Encounter campaign (nominal 24 hr/day real-time
coverage, with DSU switched off) had met expectations. Staffing of the
Ops team will undergo changes before the next SWT, with the departure of
A. McGarry at the end of August. His expertise will be missed.
Recruitment of a replacement spacecraft engineer is in progress.
Commenting on the SPC approval to continue operations until 2008, Beech
noted that a cost effective budget, together with the thorough extension
study performed by the Ops team, had been important factors in obtaining
a favourable decision.

#### Spacecraft Operations Report

[N. Angold]{.underline}, [M. Hodges]{.underline}, and [F.
Castro]{.underline} presented the Spacecraft Operations Report
(Attachment 8A).

[M. Hodges]{.underline} summarized recent operations, including the
attempts to operate the GRB experiment without its heater. Actual
operations had differed from the plan presented at the last SWT because
less power was available than anticipated during the JDE.

[N. Angold]{.underline} discussed the two Anomaly Reports that had been
raised in the reporting period. ULY060 (GAS heater 1+2 out-of-limits)
was the result of a command error, and ULY061 referred to the anomalous
behaviour of GRB following the heater switch-off. The latter is still
under investigation. Concerning an earlier anomaly (ULY058, EPC
Switch-over 2), Angold noted that the Ops team planned to disable the
EPC switch-over logic in order to remove uncertainties about the
spacecraft configuration, since TWTA2 is assumed to have failed.

Looking ahead, Angold reminded the SWT that the 9^th^ Conjunction will
occur on 7 September, with the SPE angle decreasing to 0.4º. Problems
with the comms link are to be expected. Starting on 1 October, the DSN
tracking will be reduced in accordance with the 2003 Senior Review
proposal plan (i.e., from 70 hrs per 7 days to 70 hrs per 14 days on
average). Additional coverage will be included as and when available,
however.

[F. Castro]{.underline} presented an overview of the S/C power and
thermal situation, including RTG status and predictions. **In
recognition of his long-standing interest in the RTG power output (going
above and beyond the call of duty), Lou Lanzerotti was presented with a
special RTG Power Profile certificate**. Regarding future payload
operations, Castro noted that very useful experience had been gained in
operating the spacecraft with low margins for Internal Power Dumper
(IPD) power and Reaction Control Equipment (RCE) temperatures. No
serious problems had occurred, resulting in the Ops team feeling
somewhat more "comfortable" about operating under these conditions.
Science payload operations remain tightly constrained; however, a small
amount of flexibility may be possible for short periods.

[B. Brymer]{.underline} reviewed the ground segment performance
(Attachment 8B). As noted in the Mission Operations Manager's report,
the ground segment performance was better than expected during the JDE.
Brymer presented the strategy for DSN coverage for the period October
2004 to November 2006 (reduced coverage). The following scheduling
guideline is to be adopted: gaps in coverage of up to a maximum of 19
hours will be acceptable. Commenting on the available data rates, [G.
Gloeckler]{.underline} stressed that the SWICS science return benefits
greatly from 1024 bps data.

**[NASA HQ Report]{.underline}**

[C. Holmes]{.underline} presented the NASA HQ report (Attachment 9).
Commenting on the possibility to get more DSN coverage than the nominal
35 hours per week during the "slow latitude scan", Holmes noted that DSN
usage is not paid directly out of the JPL project budget. Therefore,
there is no direct cost penalty if Ulysses is able to get more antenna
time, and if suitable slots become available, they should be utilised.
Regarding the difficult budgetary situation now facing the NASA
Sun-Earth Connection programme, Holmes reported that current planning
calls for 4 launches in 2006, with 6 missions in their prime phase in
FY07. In the wake of the new "Exploration Initiative", the SEC MO&DA
budget has effectively been frozen at the FY2004 level, leading to a
reduction of 33% by FY09. If this situation persists, it will be
necessary to terminate currently operating missions by applying a
priority scheme. Current planning is based on the ranking from the 2003
Senior Review, worked from the bottom up. Holmes stressed that there are
about 15-18 months to revise the ranking for the allocations and to seek
new funding.

Taking the SR2003 ranking at face value, however, Ulysses would have to
be terminated in FY06, since there is no allocation for FY07. Other
missions facing premature termination (April 2006) include Voyager,
TIMED, TRACE, and Geotail. The Cluster extension future is also in
doubt. SOHO (scheduled for turnoff in September 2008), IMAGE, ACE, and
RHESSI are unaffected.

Holmes assured the SWT that the SEC strategy will be to recover the
necessary funds, even on a year-by-year basis. Guidance on
prioritization is clearly needed, and so a Senior Review will be held
next year. The FY06 budget is now under preparation, implying that we
have 6-12 months to influence the process and halt the termination of
Ulysses. [L. Lanzerotti]{.underline} urged NASA to be aggressive in
achieving this goal. Under the present circumstances, the planned

review of the Nutation Operations strategy will be postponed.

####  

#### Senior Review 2005

(This item also included a discussion of the time/place of SWT-52. See
also Future Meetings)

[E. Smith]{.underline} led a discussion on the preparations for the 2005
Senior Review (in particular, the proposal), and the impact on the
planned workshop/SWT meeting in the US in the Fall. It was noted that
the 2^nd^ week of October has been earmarked for ACE and Voyager
meetings, and that the ACE teams do not favor a workshop at this time.
They want to give priority to the Senior Review and their proposal.

[C. Holmes]{.underline} informed the SWT that the draft SR2005
guidelines will be available on 1 October, in time for consideration at
the meetings in October. The scope of the Ulysses proposal was
discussed, including the suggestion by [D. McComas]{.underline} to merge
the Voyager and Ulysses proposals. Would a single 3-D and Outer
Heliosphere mission proposal be better, given that the two missions
share a program office?

[C. Holmes]{.underline} commented that NASA HQ policy is to accept all
or part of a proposal. He stressed that underlying principle should be:
Does a combined proposal suggest better science? If so, then go for it.
The international nature of Ulysses introduces a complication, however.
No consensus was reached re. a possible merged proposal. [S.
Suess]{.underline} requested an early start, regardless of the format of
the proposal.

Concerning the proposed workshop, it is clear that the senior review is
muddying the waters. The majority of the SWT felt we should not have a
workshop *just for Ulysses*. The consensus was **not to hold a workshop,
just an SWT**. The plan will be to meet in the same timeframe as ACE and
Voyager, in the JPL/Pasadena area (see Future Meetings for information
added after the meeting).

#### Science Priorities 2004-2008

[R. Marsden]{.underline} introduced a discussion on the science
priorities for the remainder of the mission (Attachment 10). The
rationale for the discussion is to provide input to the S/C Ops team in
order to prepare a payload power-sharing plan for October 2004 -- March
2008. Marsden reminded the SWT of the key mission milestones during the
period, in particular the period for which the Cold Case Heater must be
on. Marsden also noted that the approval for mission extension by both
ESA and NASA was based on the key objectives described in the respective
proposals. The were:

-   Hale Cycle effects on charged particle propagation, including cosmic
    rays and dust

-   Heliosphere-LISM interface

-   Multi-S/C observations with, e.g., STEREO.

He suggested that these, together with the technical constraints
(thermal, power) should be taken as the starting point for prioritizing
payload operations. The Core Payload as currently defined in the S/C
Operations Plan 2004-2008 comprises mag, swoops-i, swics, hi-scale, and
cospin. The Discretionary Payload therefore comprises swoops-e, grb,
dust, epac/gas, and urap. From both a technical and a scientific point
of view, changes to the Core Payload complement are effectively ruled
out (e.g., COSPIN provides essential thermal input to the --X wing, and
individual sensors can not be switched off. Even in the event of sensor
malfunction, COSPIN would have to remain on). It was also noted that
while it does contribute to the key science objectives (Hale Cycle
effects), DUST is not part of the Core Payload. Referring to the PI
Questionnaire circulated by the S/C Ops team in 2002, Marsden reminded
the SWT of the priorities stated at that time. For example, DUST and GRB
emphasized the "slow latitude scan", and joint observations with stereo
have high priority for URAP.

The draft power sharing plan shows swoops-e and epac/gas off from 1
October 2004 to 1 Jun 2007, with DUST on until the end. Marsden voiced
the concern that this was too constraining from a science point of view,
and that greater flexibility should be introduced if at all possible.
This view was shared by the SWT.

[D. McComas]{.underline}, while recognizing that hard choices will have
to be made, stressed the importance of SWOOPS-E electron data in
identifying CMEs, for example. Switching the instrument off for 2 years
was highly undesirable. [H. Krueger]{.underline} presented the case for
DUST measurements, stating that dust streams from Jupiter had been
observed once again and were expected to be seen for the next year.
Interstellar particles will then be visible again. At least 0.5 years
will be needed to gather good statistics on IS dust. [J.
Geiss]{.underline} supported this case, noting that Ulysses findings
related to the LISM/heliosphere interaction are of interest to people
outside the mission. [M. Witte]{.underline} (GAS) stressed the
importance of neutral He measurements during the 3^rd^ FLS.

From an operational point of view, time-sharing intervals shorter than 1
month are not desirable, since some instruments take 3-4 days to turn
on.

In order to help the Project Scientists and Ops team make progress in
coming to a fair and scientifically sound power-sharing plan, an
**Action Item** (AI-2) was placed on PIs to review their input to the
2002 PI Questionnaire, and to provide updates to the Project Scientists.

**[JDE Press Release]{.underline}**

[E. Smith]{.underline} led a discussion on the desirability of preparing
a Press Release on the results from the JDE campaign. The consensus of
the SWT was that more time is needed to look at the data. As an
alternative to (or in addition to) a press release, a majority of the
SWT felt that a series of short papers would be appropriate. In order to
investigate this with relevant journals (e.g. GRL, Planetary & Space
Science), an **Action Item** (AI-3) was assigned to the PIs to provide
the Project Scientists with a list tentative titles from their
investigation. By way of supporting information for the analysis of the
JDE period, Smith informed the SWT that here is an event list on the JPL
project web site that includes forward and reverse shocks. Major solar
wind structures (co-rotating rarefaction regions, HCS, CMEs, CIRs) are
also tentatively identified. Smith also pointed out that, during
interval of JDE, Ulysses was on approximately the same radius as
Cassini. The latitude difference is decreasing and longitude difference
decreases slowly to the end of 2005.

#### 

#### Archiving Activities at ESA and NSSDC

[C. Tranquille]{.underline} reported on data archiving at ESA and NSSDC
(Attachment 11). On the ESA side, it is still the plan to migrate the
UDS from the current VMS system to a PC or SUN environment. The
graphical user interface will use the CDAWeb environment. Concerning the
involvement of Ulysses in SPASE (Space Physics Archive Search &
Exchange), which is a CNES-NSSDC collaboration also involving PDS, SwRI,
RAL, etc.), Tranquille reported that there is presently no formal
connection to the UDS or NSSDC Ulysses Archives. It is the intention,
however, to bring Ulysses into the activity in the future, possibly via
the Cluster Active Archive.

[E. Smith]{.underline} informed the SWT that high resolution VHM/FGM
data has now been supplied to NSSDC. There is an interference problem in
the data that had been discussed earlier, but was worth bringing to
people's attention again. The interference takes the form of descending
and/or ascending tones that can have periods up to \~tens of seconds,
and are similar to ion-waves that are sometimes studied. Real waves are
polarized, however, while the interference is not. It is necessary to
transform the data into the S/C frame to see this.

#### Principal Investigator Reports

[G. Gloeckler]{.underline} reported for SWICS (Attachment 12A).
Instrument performance is nominal, although the known DSR/FSR anomaly
related to the very low temperature reduces the quantity of good PHA
data.

[L. Lanzerotti]{.underline} reported for HI-SCALE (Attachment 12B).
Instrument operation is nominal. A HI-SCALE team meeting was held on 31
Mar--2 Apr 2004 at APL. Concerning data archiving, Lanzerotti posed a
question of relevance to all the energetic particle experiments: How
should we deal with PHA data for archiving? It is not obvious how this
should be done. (R. Marsden comment -- Topic for a splinter meeting at
the next SWT?)

[K. Hurley]{.underline} reported for GRB (Attachment 12C). The
instrument was in good health until November 2003, with no anomalies. An
end-to-end timing test was successfully performed in November. The GRB
heater switch-off was completed without problems. The temperature on the
boom dropped to \~-60C, and discriminator-based data were good up until
turn-off on 18 November (although some sensitivity was lost). The
instrument was switched on again on 26 January. Performance was nominal
at first, but then power converter failed to start at low temperature,
leading to anomalous behaviour (ref. Anomaly Report ULY061). This is
still under study. As noted at the last SWT, Hurley would like to have
GRB on between September and December 2004 to support SWIFT. He would
also like to have GRB on for extended periods between 2004 and 2007, S/C
health permitting. This last period is important because Ulysses is far
from the Sun.

[D. McComas]{.underline} reported for SWOOPS (Attachment 12D).
Instrument performance is nominal. The October/November solar events
produced solar wind transients of \>900 km/s at Ulysses at 5 AU, with
lots of high alpha abundance.

[A. Balogh]{.underline} reported for VHM/FGM (MAG) (Attachment 12E).
Instrument operation is nominal. Funding at Imperial College is minimal
for Ulysses, so that data reduction is limited to the basic
requirements.

[M. Witte]{.underline} reported for GAS (Attachment 12F). Instrument
performance is nominal, and survived the erroneous mode change (ref.
Anomaly Report ULY060) with no ill effects. No detections of Jovian
neutrals were made, but the expected intensities were only \~2x above
background.

[N. Krupp]{.underline} reported for EPAC (Attachment 12G). Instrument
performance is nominal. Weak evidence for Jovian electrons was seen
after 4 February.

[H. Krüger]{.underline} reported for DUST (Attachment 12H). The DUST
instrument is in good health. Krüger has moved from Heidelberg (MPK) to
Lindau (MPAe), but will remain PI. Eleven Jovian dust streams have been
detected so far, the most distant at 3.3 AU from Jupiter. The impact
direction is apparently correlated with the IMF, and there is (very
roughly) \~25 day periodicity. This has not yet been related to anything
in the solar wind.

[B. McKibben]{.underline} reported for COSPIN (Attachment 12I). All
parts of the COSPIN instrument are working nominally. Electron jets from
Jupiter have been detected, and are confined to narrow flux tubes. If
they represent magnetic connections, the field lines are strongly
deflected.

[R. MacDowall]{.underline} reported for URAP (Attachment 12J).
Consistent with the payload switching plan, URAP is currently off. Both
instruments functioned nominally in March-April. Very little solar
activity was seen between November 2003 and March 2004. Jovian radio
emission is seen each day, however. Interesting 'new' emissions and
recurring patterns are being analyzed.

Earlier in the meeting, MacDowall informed the SWT of the death \~6
weeks ago of Bob Stone, the original PI of URAP. Dr. Stone was buried in
Arlington National Cemetery.

#### 

#### Future Meetings

[R. Marsden]{.underline} reviewed the sessions of interest and/or
relevance to Ulysses at the upcoming COSPAR meeting in Paris, France
(Attachment 13A). [P. Wenzel]{.underline} informed the SWT that posters
at COSPAR will be on display for 3 days.

[T. Zurbuchen]{.underline} described the plans for Solar Wind 11
(Attachment 13B). The meeting, which will be joint with SOHO 16) will be
held in Whistler, Canada, in June 2005. The intention is to have a very
international meeting, and to encompass all of the solar and heliosphere
communities. Sessions will cover developments in the past 4-5 years, and
expectations for the next 4-5 years.

#### 

**[Date of SWT-52]{.underline}: Following the meeting, it has been
decided to hold SWT-52 and related meetings between 5 and 8 October, at
a TBD location in Southern California. A meeting to discuss the 2005
Senior Review preparations will be held on 5 October (Tuesday). The JWG
will meet the morning of 6 October (Wednesday), which will also be
available for team meetings. SWT-52 will start after lunch on 6 October,
continuing all day Thursday (7 October), and finishing at lunchtime on 8
October (Friday).**
