40 days and counting. The long wait is almost over!
I wonder whether we will get enough data to test new simulation theories like this one. http://space.newscientist.com/article/mg19...solar-wind.html What do you expect from this first flyby? |

Looks like Ulysses could be troubleshooting for several days. This from the Operations Summary:
15 January EPC 1/TWTA 1 Switch off/on Test 1 - 015.01:18 ERT. Operational test to validate future mode of operations. Failure to re-acquire X-band downlink at the expected time. Commands to switch EPC/TWTA 1 repeated without success. S/C now configured to S-band downlink. 16 January TBD 17 January TBD 18 January PPSP configuration change - GRU ON - 018.hh:mm SCET. It's at http://ulysses-ops.jpl.esa.int/ulsfct/opssumm.html |

Things always seem to work themselves out, don't they? Oh well, at least MESSENGER didn't have a cosmic ray trip 30 minutes or so after C/A.
Do they really need the 70m dish to receive from basically our neighborhood? -------------------- |

I hate to sound mean, but if they were testing some new operations mode that involved turning the transmitter off and on in the middle of the Messenger flyby, they ought to have to wait until the Messenger data is downloaded. This is probably my impatience speaking

At noon today, the highgain download from MESSENGER was to start, but... my spy in the APL Kremlin reports (I got the email at 12:31 PM) that Ulysses (which is north of the sun on it's polar pass) declared an emergency, AND the 70 meter DSN dish that was to be used has a transmitter problem. So NO high gain down load today from Mercury space.
But the housekeeping data from MESSENGER says that the observations were completed and the data is stored. :-) Rob Need more DSN... |
