Attitude Manoeuvres:

q      Wednesday, 15.January 2003 between 10:00 (160) and 18:00 UT (177) with a back-up on Friday, 17.January 2003 between 13:00 (144) and 19:00 UT (162).

q      The subsequent orbit correction manoeuvre could be carried out on Friday, 24.January 2003 around 03:30 UT.

17/19 November 2002 131

Leonid Meteor Shower:

The predictions are for a double peaked storm on 19 November:
q      around 0400 UTC, when the Earth intercepts dust ejected from the source comet in 1767
q      around 1000 UTC, when the Earth intercepts dust ejected from the source comet in 1866

These peaks are close to the outbound magnetopause on orbit 369.

There is a third possible encounter on 17 November at 19:30, 11 hours after apogee of orbit 368. At this time the Earth will pass the dust ejected from the source comet in 1966.

Constellation change manoeuvres (June-July 2002):

q      Detailed timing of the manoeuvres on the 27 May 2002 (excluding uncertainties): manoeuvres_2002_06.htm

Uncertainties are:

  • the manoeuvre start times may be shifted by 15 min
  • duration may be extended by 5 min

q      Baseline on the 29 January 2002 and type of manoeuvres2: cma_ns2_cu3.pdf

q      Please see also http://jsoc1.bnsc.rl.ac.uk/pub/msp/  for the planning during the manoeuvres.

Re-allocation of the EDI Science TM to PEACE on SC4.

q      Baseline on the 28 February 2002: The operations will start, in week 11, at 2002-03-12T06:52:12Z and last for 009:12:03.

However, this schedule assumes that the new up-linker software will work. If everything goes according to plan then the new up-linkers will be installed on all relevant computers in week 10.
