Nasahtaako?

Kaikki _tietenkin seuraavat_ tuota avaruusaseman liikkeitä.:D Observatoriot kyllä tekevät pitkäjänteistä työtä, joka on suunniteltu ennakolta hyvinkin tarkkaan. Tarkkailevat huomattavasti kaukaisempia kohteita missä avaruusasema lentää.

Joo, multa karkasi munkki kesken avaruuskävelyn tsajutauon. Terv. Keijo Kosmonautti.

Hyvin syväluotaava tutkimus. Yhdyn päällikköön.

Kohde on joko horisontissa, tai linssiheijastus. Linssiheijastus kumoutuu, sillä kamera ei ole aluksen sisällä, ja siihen samaan kameraan ei kohdistu muissakaan livelähetyksissä heijastuksia aluksesta. Lähetyksen katkaisemine joko liittyy objektiin tai sitten ei liity. Olisko viides kerta tänä vuonna?

Miksi lähetys katkaistiin roskan takia.

Miksi lähetys katkaistiin roskan takia.

"This video is only available when the space station is in contact with the ground. During "loss of signal" periods, viewers will see a blue screen. Since the station orbits the Earth once every 90 minutes, it experiences a sunrise or a sunset about every 45 minutes. When the station is in darkness, external camera video may appear black, but can sometimes provide spectacular views of lightning or city lights below."

Nykytekniikalla pimentoja ei olisi, ellei niitä olisi keksitty piilottelemaan ikäviä näkymiä. Kyse on kuitenkin maailman teknologian huippunäytteestä, ja sellainenko sitten pimenee jatkuvasti.
Samoin oli jo kuulentojen ja sukkulalentojen aikaan.
"We have a boogey here" kun kuului radiosta niin lähetys yllättäen katkesi. Radioamatöörit on muutaman toiselle kanavalle siirtyneen keskustelun tallentaneet. Siellä puhutaan ihan reippaasti kuinka alukset seuraa ja Apollo 11 laskeutumispaikan vieressä oli valtava ufoalus parkissa. Siksi Armstrong ja kumppanit olivat niin järkyttyneitä palattuaan. Pitivät sisällään ihmiskunnan suurinta salaisuutta.

"The reason for the loss of signal (LOS) is because the ground station that receives the downlink from the tracking and data relay satellites (TDRS) is located in southern New Mexico near Las Cruses. Since the satellites must have a line of sight view to the ground site they can only be so far apart. The primary TDRS satellites used by the shuttle are located at -174 degrees West and -41 degrees West. These are about as far apart as they can be and still see the ground site. The shuttle must have a line of sight view of the TDRS as well. There is a small area over the world where the shuttle can't see the satellites. That is the LOS or zone of exclusion (ZOE).

There are several other TDRS satellites in orbit. Some of them are very old as far as satellites go and have lost some of their capabilities. The shuttle has 4 satellites available to it including the two that it primarily uses. For the shuttle to use these other satellites a command must be sent to the shuttle to tell it which two satellites to use. We do this to support the deorbit burns and any very critical time frames like the MIR dock and undock times on STS 86.

The South Atlantic Anomaly (SAA) does not have any affect on the TDRS links to the shuttle or the ground. The main impact of the SAA is on the laptop computers and the TV cameras on the shuttle. If you look real close during a night time downlink of the payload bay cameras you will see a streak of colored light. That is a proton hit on some of the camera image elements. Over time the pixels (image elements) can be damaged by the SAA. You can see that as spots on the picture. The laptops that fly on the shuttle are just like the kind that you can buy in the store. They can be affected by the same thing that affects the cameras. The impact is that the computers will stop working because the proton has hit the memory of the computer. All the crew has to do is power off then on to fix the computer."

Niin niin, mutta miksi lähetys katkaistiin roskan takia.

Niin niin, mutta miksi miksi miksi miksi.

Miksi ufouskovaiset ei meuhkaa silloin kun lähetys katkaistaan eikä ISS-videossa näy minkäänlaista roskaa tai heijastusta?
Silloinhan se NASAn salaaman täytyy olla TODELLA SALAISTA!

Sammutellaan jotta saadaan syy sammutella sitten kun tarvii sammutella syystä. Vanha kikka.
