E como habitual, a nave Discovery está de novo atrasada no calendário para ser lançada. Já vão dois adiamentos embora, estes sejam devido a condições do tempo adversas.

Mas os problemas só agora começaram....A imprensa é que não diz nada porque não convém assustar as pessoas...
Geomagnetic storms and space shuttle missions don't mix
Here are the effects of the G4 stoms.
Only G5 ranks higher.
Wonder why they launch these things when they know the sun is acting up...
EFFECTS OF G4 GeoStorming:
Power systems: possible widespread voltage control problems and some protective systems will mistakenly trip out key assets from the grid.
Spacecraft operations: may experience surface charging and tracking problems, corrections may be needed for orientation problems.
Other systems: induced pipeline currents affect preventive measures, HF radio propagation sporadic, satellite navigation degraded for hours, low-frequency radio navigation disrupted, and aurora has been seen as low as Alabama and northern California (typically 45° geomagnetic lat.)
