## New Horizons

- Pluto flyby mission with Jupiter gravity boost
- Jupiter Flyby - Jan-April 2007
- 32 datasets from 8 instruments + SPICE, ~100 GB
- No data from some instruments with no science at Jupiter
- Painful peer review, extensive lien correction (big effort by NH archive team), corrected delivery posted for JDAP (big increase in web hits at SBN)
- Fixing minor details for final archive, ver 1.0
- Expect delivery of ver 2.0 (better calibrations) in summer 2008, peer review in fall?
- Future events
- JDAP Products
- Pluto in 2015

## Rosetta

- Lander/Orbiter mission to Comet C-G
- Ground-rules
- ESA-NASA MOU requires full archive in PDS (predates existence of PSA)
- ESA Project Scientist does NOT want to change MOU to archive only in PSA
- Status
- Data from 2 Earth flybys, Mars flyby, remote observations of Deep Impact and C/Machholz
- All peer reviewed (PSA still learning to run peer reviews)
- US Instruments
- ALICE - 12 datasets, 2.3 GB; liens resolved, on-line
- MIRO - 7 datasets, 3.1 GB; Reviewing new data from Mars and DI events since PSA reviewer had problems reading data; data may not be compatible with standard tools
- IES - 4 datasets, 0.7 GB; lien resolution nearly complete

## Rosetta (cont.)

- Status (cont.)
- Non-US instruments - 10 total
- Validation with PDS tools has shown incompatibilities with PSA in many details - most have no effect on scientific usability but problems inhibit ingestion
- Some instruments, notably VIRTIS, have data that can only be read with their own software - ok by PSA but not by SBN
- SBN negotiating with PSA on incompatibilities and on release schedule
- Future Events
- Flyby asteroid Steins  6 Sep 2008
- Flyby asteroid Lutetia  10 July 2010
- Acquire P/Churyumov-Gerasimenko  May 2014
- End of mission  Dec 2015?

## EPOXI

- Combination of EPOCh (observations of extrasolar planets) and DIXI (flyby of a second comet) with DI flyby spacecraft
- Status
- Target changed (in Nov 2007) from P/Boethin encounter in Dec 2008 to P/Hartley 2 encounter in Oct 2010
- EPOCH observations currently underway
- Various problems in telecom system have interrupted EPOCh observations and may require observations beyond scheduled end in June 2008
- Pipeline upgrade nearly complete to deliver PDS-labelled products
- Expected archive after EPOCh
- 80 GB raw from cruise + EPOCh
- 120 GB calibrated from EPOCh
- EPOCh data also delivered to MAST

## EPOXI (cont.)

- Future Events
- Encounter with P/Hartley 2   11 Oct 2010

- PDS MC Mtg

## Stardust NExT

- Flyby of Comet Tempel 1 to study effects of DI and of evolution
- Status
- DMAP in negotiation between SDC and SBN but close to final signature
- S/C conditions nominal
- Future Events
- Flyby of Tempel 1   14 Feb 2011

- PDS MC Mtg

- 3 Apr 2008

## Dawn

- Orbiter of Ceres (largest asteroid) and Vesta (highly evolved, large asteroid)
- Status
- SISs in preparation - disagreements on data delivery, both schedule and format, between SDC and non-US instrument teams
- Note policeman issue on last slide
- Future Events
- Mars flyby  2009
- Vesta orbit  2011
- Ceres orbit  2014

- PDS MC Mtg

## Hayabusa

- Asteroid orbiter/lander and sample return
- Ground-rules
- Archive responsibility with US science team members
- All data to PDS since no Japanese archive in place
- Status
- Japanese have made imaging data public in non-PDS compliant form
- SBN taking over much of the activity expected from US science team (but Paul Abell helping a lot)
- Note policeman issue on last slide
- Peer review scheduled for June 2008
- Amica
- Lidar
- Shape Model (Gaskell)

- PDS MC Mtg

## Hayabusa (cont.)

- Status (cont)
- Data not ready for review
- NIRS - lacking pointing information
- Radio Science - Yeomans unable to obtain data from team
- XRS - no supporting documentation to interpret data; marginal quality, may not be archived
- SPICE - kernels on JAXA site; NAIF has no plans to archive
- Future Events
- Sample return to Australia
- Don’t know if they have a sample or not due to s/c cpu problems

## Cassini

- SBN responsible only for dust instruments
- Data being delivered quarterly from HRD and CDA

- PDS MC Mtg

- 3 Apr 2008

## Future Missions

- New Frontiers
- From original decadal survey, might expect CSSR
- If scope expanded, might expect an NEO sample return
- Discovery
- Comets and asteroids are the easy targets (after the moon) for Discovery-class missions and offer good science
- Expect > 1/2 of future Discovery missions to be comets or asteroids

## Restoration and DAP

- Deep Impact
- Thermal maps to be re-reviewed in June due to large work put into addressing requests of reviewers
- Still archiving ground-based data from various sites
- Expect several products from DAP this year
- Stardust
- Reformatting products for use by astronomical community
- Calibration of NAVCAM is wrong!
- SBN plans to recalibrate (not in scope of PDS, but Stardust project no longer exists)
- SOHO
- Archiving all cometary data with improved photometric reduction (thesis project funded under Planetary Atmospheres program)
- Other
- IHW Vega data being restudied at request of Russians
- Galileo and Ulysses dust data being worked on

## Telescopic and Lab Data

- Support data from missions (DI, NExT, DIXI, Dawn)
- Ground-based surveys
- What to do about PanStarrs???
- Lab spectral data relevant to asteroids and comets
- Returned samples
- Little progress in negotiating with curation facility at JSC

- PDS MC Mtg

## Software Tools

- OLAF (On-Line Archiving Facility)
- Used to archive ~80 datasets since 2003
- Most datasets in asteroid/dust subnode are prepared through OLAF
- SBN IDL
- Now a joint effort with PSA (under CVS managed at SBN)
- New data products are a challenge (e.g. VIRTIS cubes)
- SBN Cross-ID tool
- Requires approx bi-monthly updates
- Needs to be ported to new machine and O/S
- Ferret
- A search tool combining previously independent efforts for comets and asteroids
- Much more development needed
- Mirror site
- Currently developing automatic mirroring (really a backup) on a single site
- Will then use UM and PSI to mirror each other

## Minor Planet Center

- ROSES 2008 calls for proposals to operate MPC, preferably as a part of SBN
- SBN originally opposed bringing MPC into SBN because operation is so different
- Budget for MPC will come from NEO program according to NEO program exec
- Burden on SBN TBD
- Don’t know who will win proposal
- Will require negotiation on what to archive and how often
- What is role of SBN for the many non-archival products?

## Big Issues

- 6-month delivery period for most missions is very tight for many instruments to calibrate properly
- Good-cop bad-cop scenario says PDS should be the good cop and NASA should be the bad cop
- Can’t deal properly with DAP products (or even mission products for that matter) unless we know from NASA what has been promised.  PDS does not have access to the proposal material
