TARANIS PHASE B : HOT SPOTS
1. XGRE development
2. Mechanical accommodation
3. Orbit parameters
4. Launch opportunities

TARANIS PHASE B HOT SPOTS : XGRE development
■ The development of the X and Gamma Ray Experiment (XGRE) is not yet
granted
■ XGRE (with a cooperation of the DNSC) was supported by LANL and since last Sept.
by JHU/APL with the hope of NASA funds
■ But NASA did not select XGRE through the SMEX MO selection (announcement
NASA HQ, June 2008 - Friday 20th)
■ XGRE instrument is an essential part of the TARANIS payload
■ A new organization must be found for XGRE

TARANIS PHASE B HOT SPOTS : Mechanical accommodation
1. A large set of scientific instruments with different FOV
requirements
2. Several alignments constraints between instruments
3. Several deployment devices required
4. Thermal constraints
5. Integration constraints
6. Launcher constraints

TARANIS PHASE B HOT SPOTS : Launcher constraints
■ CNES mission has to respect the European Launcher Policy
(Dec.06)
■ European launcher operators first
■ Launchers taken into account : AR5, SOYOUZ, VEGA
■ Back-up solutions : DNEPR, ROCKOT
Up to now, for MYRIADE missions,
SOYOUZ (launched from Kourou) as piggy-back is the nominal solution

Next steps
■ Modifications to the accommodation baseline
■ Negotiation with Arianespace
■ Adaptation of the instrument requirements (FOV, alignments, …)
■ Ultimate step : de-scoping negotiations with PIs

TARANIS PHASE B HOT SPOTS : Orbit parameters
Orbit parameters requirements :
Quasi polar orbit, altitude between 650 and 750 km,
quasi SSO (Sun Synchronous Orbit), local time drift [22h00,2h00]
■ As far as TARANIS satellite is not the main payload of the launcher,
high probability to be launched on a pure SSO without local time drift
■ We have to respect the
European Code of Conduct for Space Debris Mitigation
→ re-entry rules before 25 years
■ Propulsive capacity of the satellite will be mainly devoted (95%) to injection corrections and re-entry
operations : nearly nothing left to modify the local time or the drift

TARANIS PHASE B HOT SPOTS : Orbit parameters
Orbit parameters question
Highly linked to the launch opportunities and the capacity of
re-ignition of the last stage of the launcher
At the scientific level, necessity to refine or adjust the orbit
requirements : local time range.
→ Definition of which hours are forbidden, acceptable, optimal

CONCLUSION
■ TARANIS mission is very well supported by the scientific community
■ The CNES CPS strongly support the TARANIS mission
■ Good scientific and technical international cooperation
■ Technical matters has still to be solved (accommodation)
■ But, we have to find a way for XGRE instrument
→ Impact on the planning to be evaluated at the Project Level
