New Horizons Status A’Hearn & Kolokolova
Mission Overview • New Horizons launched 19 Jan 2006 • En route to Pluto with Jovian gravity assist • Closest approach to Jupiter 28 Feb 2007 • Speed 21 km/s • Closest approach 32 RJ (3x closer than Cassini) • Pluto flyby July 2015 Management Council
Payload • ALICE - uv spectrograph • RALPH - optical/IR • LEISSA - Linear etalon spectrometer (IR) • MVIC - multispectral visible camera • REX - radio wave occultations • LORRI - long-range imager • SWAP - solar wind analyzer • PEPSSI - energetic particle spectrometer • SDU - dust counter (student built) Management Council
Archiving Status • DMAP signed • ICD - implicit in DMAP • SIS - • Preliminary version reviewed for each instrument • Final version not yet available (but preliminary versions were prettty good) • Data • No sample data available yet • No calibration data available yet • Pipeline • All data to be processed at SOC (at SwRI Boulder) • Peer review of pipeline discussed several times over last year but never held Management Council
Recent Developments • Jim Green announced that there will be a JDAP for New Horizons using FY07 money • SBN held discussions with New Horizons regarding “typical” requirements for data delivery to PDS for DAP eligibility • Kolokolova and Raugh attended SOC + Science Team meeting in November • New Horizons team still neither willing to schedule a pipeline peer review nor willing to provide sample data Management Council
Current Plan for Jovian Data • Data taken and downlinked January 2007 to July 2007 • April delivery of data through closest approach - both raw and calibrated (a change from plan as of two months ago) • All Jovian data will be delivered in August-September, including re-calibration of early data • Noting the huge improvement in their plan, we presume NASA told them they had to deliver in order to get DAP funds Management Council
Data - Format & Volume • ALL data will be in PDS-labelled FITS format • This partly a result of A’Hearn’s attendance at an early science team meeting to urge uniformity across instruments - advantages recognized instantly by science team • Estimated volume at Jupiter • ALICE - 5 Gbits, images • LEISSA - 18 Gbits, cubes • LORRI - 12 Gbits, images • MVIC - 1 Gbit, images • PEPSSI - 10 Gbit, table • REX - 26 Mbits, table • SWAP - 900 Mbits, table • SDC - ?? Management Council
PDS Roles • Until now, all interaction with SOC has been by SBN • Minimizes need for SOC to deal with node-to-node vagaries • ATM interested because data at Jupiter are mostly atmospheric • PPI interested in SWAP and PEPSSI • Radio Science interested in REX • Original plan was to involve other nodes at time of pipeline review - with decision not to have a review, what should be role of other nodes? Don’t want SOC to have to deal with multiple nodes (cf ESA PSA position) Management Council
