Why will today's lunar flyby only beam back low-resolution video?
Without negating the history of the moment, when on Monday (April 6) the fresh eyes of four astronauts catch sight of the up-close moon, it will take a bit longer before the rest of us on Earth are able to see what the Artemis II crew saw at the same clarity.

"
US spy satellites built by SpaceX send signals in the “wrong direction”
"
"It seems US didn’t coordinate Starshield’s unusual spectrum use with other countries."

"
Geheime SpaceX-Satelliten funken auf verbotenen Frequenzen
"
"Ein Netzwerk streng geheimer Satelliten des US-Raumfahrtunternehmens SpaceX sorgt derzeit fĂĽr Unruhe unter Experten. Denn sie senden Signale auf Frequenzen, die sie in dieser Form eigentlich gar nicht nutzen dĂĽrfen."

"Use of those frequencies to #downlink data runs counter to standards set by the International Telecommunication Union, a United Nations agency that seeks to coordinate the use of radio #spectrum globally. #Starshield's unusual transmissions have the potential to interfere with other scientific & commercial satellites, warns Scott Tilley, an amateur #satellite tracker in Canada who first spotted the #signals."

“Earth’s perihelion happens close to the New Year every year. Earth's orbit around the Sun isn't perfectly circular, so we get closer to and farther from the Sun depending on where we are in that orbit. In 2024, perihelion — our closest point to the Sun — will be on Jan. 2-3” - The Downlink #Downlink #PlanetarySociety
“In 3.5 years, The Planetary Society’s LightSail 2 completed 18,000 orbits of the Earth and journeyed about 8 million kilometers (5 million miles) in total.” - The Downlink #PlanetarySociety #Downlink
