(27,168 posts)And I hadnt thought of that but what I did think was that Apollo was never a great name for an expedition in a science-fiction story but Artemis certainly is. I have spent my conscious lifetime reading science fiction going all the way back to Fantasy and Science Fiction and Analog magazines as well as collections of the pulp publications from the 40s and 50s in the early 60s and a garden-variety space story would have a ship called Artemis. Just my two cents

(36,631 posts)NASA Television programming on the Galaxy 13 domestic satellite is moving from transponder 11 to transponder 15. This move is in line with the Federal Communications Commissions initiative to free up C-band bandwidth on domestic satellites in support of future 5G terrestrial communications efforts. As part of that transition, the modulation format will be changed from DVB-S/QPSK to DVB-S2/8PSK effectively reducing the transponders required bandwidth. See more detailed specifications below. Currently, both transponders are active. Distribution of NASA TV programming on transponder 11 will end on Aug. 29, 2022. It is important that all affiliates and end-users begin to transition to the new transponder to prevent the loss of NASA TV programming.
NASA Televisions channels NTV-1 (the Public/Education Channel) and NTV-3 (formerly the Media Channel) are in high definition. NTV-1 provides expanded programming of events of interest to the public and to educational audiences. NTV-3 provides mission coverage, news conferences and video/audio material relevant to local, national, and international news-gathering organizations. NASA's Ultra High Definition (UHD) NTV-4 channel provides various live and previously recorded programing in a 2160p video format.
All NASA Television channels are available on the Galaxy 13 domestic satellite. Specific parameters for each channel are listed below.
News networks, their reporters, and other broadcast media organizations must tune their satellite receivers to the NTV-3 to ensure reception of clean feeds for all mission coverage, news conferences, and other agency distributed news and information. NASA TV is available in continental North America, Alaska, and Hawaii on Galaxy 13. A Digital Video Broadcast (DVB-S2) compliant Integrated Receiver Decoder (IRD) will be needed for reception on transponder 15. Below are parameters for each channel:

(16,332 posts)My son is a NASA engineer at KSC and he didn't find out until Friday that he was one of the lucky ones to get a car pass to attend the launch. He's been on the Artemis program since he started working there. I had all intentions of hopping a flight if I heard he had gotten a pass but it was too short notice.
I'll follow his facebook page this morning just to see his photos. It's starting to look like it may not go. In that case, there will still be time for me to get down there by Friday, the next launch date.
