Project News

2015 Heliophysics Senior Review released on June 30

The 2015 Heliophysics Senior Review panel undertook a review of 15 missions currently in operation in April 2015. From the proposals submitted by the projects, the panel was charged to make their assessments and evaluate each of the operating missions. 

In the overall mission ranking Van Allen Probes received the highest grade along with IBEX and IRIS.

The panel noted no weaknesses in the Van Allen Probes Mission proposal The opening paragraph of the Overall Assessment reads:

“The panel noted the great impact and exceptional scientific returns derived from the Van Allen Probes mission in its prime mission phase. The panel further noted the compelling science proposed for the extended mission phase, which both builds on the extensive scientific discoveries from the prime mission and which utilize new and optimized orbital configurations including new data and burst modes and benefit from increased data rates to the ground. Together with existing and new assets in the HSO, as well as through coordinated operations with a number of upcoming cube satellites and the Japanese ERG mission the panel finds the proposal compelling and expects a significant ongoing level of high impact science returns from the mission."

Orbit Adjustment Maneuver

One of the major components of the Van Allen Probes Extended Mission proposal, noted in the Senior Review, is the orbit adjustment maneuver that increases the separation between the the apogees of Probe A and Probe B. The maneuver will increase the spacecraft lapping rate by about a factor of 2 and speed up the separation of the lines of apsides, which will also result in more frequent radial conjunctions. These orbit modifications are key for addressing the prioritized science goals of the Extended mission.

The PIs of the Instrument teams had a teleconference on June 30 to discuss different scenarios of the apogee maneuver suggested by the Project Science team. The PIs reached a consensus to go forward with option 2, i.e., to adjust the apogees of both spacecraft by 70 km. This option enables substantial orbit modification with minimal impact on the mission lifetime. The spacecraft team began designing the maneuver. It will be implemented in early September. 

The proposal for a JGR Special Issue “Big Storms of the Van Allen Probes Mission” submitted to M. Liemohn with a tentative deadline of December 1, 2015

Session and Discussion Questions1) Does the presence of NL waves affect the conclusion that QL acceleration suffices? 2) What are the detailed structures and effectiveness of the microphysical processes that act to energize radiation belt particles in the inner magnetosphere? 3) For shock-stimulated acceleration events, what is the relative acceleration by ULF waves extending over hours as compared to that caused more coherently by the initial shock impulse?

4) Which of the following contribute the most to magnetopause losses: MP motion, ULF waves, shell splitting, orbit bifurcation, or ring current inflation? 5) What is the relative importance of the mechanisms that cause precipitation? 6) How important are NL wave interactions in precipitation loss? 7) What is the relative importance of precipitation and MP losses for varying solar cycle conditions?

8) How do mesoscale injections and global processes transport particles into the ring current, slot, and inner zones? 9) What are the spatial, temporal, energy distributions produced by different transport/injection mechanisms? 10) How do electron and ion injections into the inner magnetosphere affect or modify the global distribution of geoeffective magnetospheric waves? 11) What mechanisms operate at the injection front to convert flow energy into kinetic NL electric field structures?
