With the possibility of a faster roll mode, science-driven roll manoeuvres may again be possible. SUMER have requested one along the lines of the 1997 roll manoeuvre (see annex 7).
MDI and SWAN would also benefit very much from a roll. An action was (action 33-2) put on PIs/instrument teams to define requirements for SOCs who will work on final time line.
The roll would most likely be performed between 2 - 7 December.
A repeat of the off-point manoeuvre would be desirable for EIT and MDI, and the suggested time would be April 2002 (after 3-month MDI continuous).
