| Jutro słuchacie? 24 maja komunikat od pozaziemskiej cywilizacji |
| Europejska sonda kosmiczna krążąca wokół Marsa nada symulowany komunikat od pozaziemskiej cywilizacji. Każdy może wziąć udział w próbie zdekodowania go i odczytania informacji. Globalny projekt nosi nazwę A Sign in Space. https://www.urania.edu.pl/wiadomosci/sonda-kosmiczna-zasymuluje-sygnal-od-pozaziemskiej-cywilizacji https://asignin.space/ https://www.seti.org/press-release/first-contact-global-team-simulates-message-extraterrestrial-intelligence-earth znaczy interpretujecie sygnał? Sygnał z Trace Gas Orbiter (TGO) Wikpedia ujawnia: Communication 2.2 m (7 ft 3 in) X band high-gain antenna with a two-axis pointing mechanism and 65 W RF travelling-wave tube amplifier to communicate with Earth Two Electra UHF band transceivers with a single helical antenna to communicate with spacecraft at Mars I o ile dobrze szukam The C/TT-510 Electra-lite Transceiver is flexible enough in its design to accommodate many mission scenarios where data links are required between two spacecraft. The unit can be configured in the factory for full-duplex or half-duplex operation. A unit configured for full-duplex operation with coherent transponding offers navigation capabilities like two-way Doppler ranging as well as the capability to be upgraded with future ranging algorithms. The bands are in-flight tunable in 56 kHz steps over 390-to-405 MHz for transmit and 435-to-450 MHz for receive. This is the reduced mass version of the C/TT-508 Electra Transceiver. This transceiver is ideal for lander missions with stringent mass and energy constraints. Electra-Lite maintains the core functionality, performance and reprogrammability of the standard Electra. |
