Hi When and where first SDO images will be available? Thanks When ? The "Official" line is 60 Days. 59 now But Goddard still has a number of tasks to perform before SDO is ready for "First Light". Where ? No word on that yet but one would suspect the SDO Website sdo.gsfc.nasa.gov (BTW their server went down last night so the website could be down for the weekend) |

Hi I wondered if someone has an idea of what the images sent from SDO will look like compared to SOHO? How big an improvement will there be? I could search on google for it but I'm lazy right now  Can someone care to share how big an improvement SDO will be over its predecessors perhaps by providing a comparative between them? Thanks The cameras on AIA are 4K x 4K which comes out to 16 Mega Pixels. Which is 4 times better than HDTV. I don't know what the resolution on SOHO is but it probably was the best technology available in 1990 when SOHO was designed and built. But just as important they will operate differently because they are in different orbits. SOHO is in a Heliocentric Orbit so it has to buffer it's data and wait for a DSN Station to become available.. SDO will be in geostationary orbit and will beam it's images down directly to a dedicated ground station in real time. This also will also improve the quality of the images returned because Data Compression used on SOHO will not be necessary. AIA will beam down a new image every 10 Seconds SOHO' s rate is one every 3 minutes. That is for one instrument. Want more ? That's excellent! Thank you for the information, I had no clue it would be such an improvement over SOHO! |

It could be weather related or maybe they are preparing for a Post Launch Roll-out of a new website. We can only hope. Bob |

It kinda looked like the CBS seeing eye logo to me. |

There are a couple videos of the shock wave from the Atlas V Rocket that boosted SDO taking out that Sundog. It certainly is cool.
BTW SDO's GSFC Webpage is reporting that it has completed it's first of nine propulsion system burns to circularize it's orbit.

Well the second burn didn't go so well. It was aborted after 30 seconds. Controllers don't believe there is a problem with the Satellite. The computer dumped the burn when a high momentum value was detected. Inititial assessment points to a flight parameter that was set too low on board SDO's computer. After evaluation controllers GSFC was scheduled to perform another burn Sunday Night. Nothing has been reported as of Noon Monday.

Relax George A report just released states that Sunday Night's burn was completed successfully using the Satellite's manuevering engines. The perigee was raised 900 miles. Goddard suspects the problem lies with the initial thrust of the main engine causing the fuel to slosh. They are working on devising a solution. The satellite is operating fine. All of the instruments are powered although their doors are closed and the manuevering system rolls the craft between sun pointing and boost attitudes when called upon just fine. |

GOES P will be launched a week from Tuesday. It will be the last in the GOES N Series and will be carrying a suite of Solar X Ray Sensors, a Solar X Ray Imager plus Solar UUV monitoring equipment. www.nasa.gov/mission_pages/GOES-P/main/index.html |

Oh that reminds me of a good joke I'll put down in the catch all section. |
