    The BepiColombo Mercury Transfer Module (MTM) has returned its first image from space. The view looks along one of the extended solar arrays, which was deployed earlier this morning and confirmed by telemetry. The structure in the bottom left corner is one of the sun sensors on the MTM, with the multi-layered insulation clearly visible.

    The transfer module is equipped with three monitoring cameras, which provide black-and-white snapshots in 1024 x 1024 pixel resolution. The other two cameras will be activated tomorrow and are expected to capture images of the deployed medium- and high-gain antennas onboard the Mercury Planetary Orbiter (MPO).

    The monitoring cameras will be used on various occasions during the cruise phase, notably during the flybys of Earth, Venus and Mercury. While the MPO is equipped with a high-resolution scientific camera, this can only be operated after separating from the MTM upon arrival at Mercury in late 2025 because, like several of the 11 instrument suites, it is located on the side of the spacecraft fixed to the MTM during cruise.

    BepiColombo launched at 01:45 GMT on 20 October on an Ariane 5. BepiColombo is a joint endeavour between ESA and the Japan Aerospace Exploration Agency, JAXA. It is the first European mission to Mercury, the smallest and least explored planet in the inner Solar System, and the first to send two spacecraft to make complementary measurements of the planet and its dynamic environment at the same time.

    ARCHIMEDES: 1000mm ne, spis tech 500-800 max, ja mam doma 400mm a kdyz fotim mesic, je to o neco mensi jen. (fullframe)

    DRAGON: Krom toho dynamického rozsahu a dalších věcí, když porovnám ty poloměry s realitou, odpovídaly by fotce ze vzdálenosti cca 200 000 km od Země. Pokud by to nebyl výřez, byl by to teleobjektiv přes 1000 mm (kinofilm ekviv.).
    Ale obrázek je to jinak hezkej :)

    Tohle je fotka. Nejsou tam vidět hvězdy, protože je to *hodně* stops pod expozicí, kterou potřebuješ na nepřepálenou fotku osvětlené Země a Měsíce a ten je daleko menší, protože... prostě je. Buď máš Měsíc přes celou fotku ale Země je pak skoro rovná, nebo tam zakřivení je vidět ale Měsíc bude mít pár px :-)

    Watch out, America! #HurricaneFlorence is so enormous, we could only capture her with a super wide-angle lens from the @Space_Station, 400 km directly above the eye. Get prepared on the East Coast, this is a no-kidding nightmare coming for you. #Horizons

    TURNPIKE: Pravda, vubec jsem elypsu nevzal v potaz... :-( A ani fakt, ze v pripade pohybu po elypse, jak je naznaceno se meni rychlost dost vyrazne, takze "2.5% c" bude jen max rychlost... :-(

    BLACKHEAD: vypocty mas ozaj chabe, kedze si pravdepodobne ratal s pohybom po kruznici. v skutocnosti obieha s e=0.87, takze S0-02 obieha okolo barycentra vo vzdialenosti 120AU v periapsi a 1730 AU v apoapsi

    TROGLODYT: Dle mych chabych vypoctu z toho vyplyva, ze ta 15-ti leta hvezda tu diru obiha zhruba ve vzdalenosti 2722 AU. Wau :-o

    TROGLODYT: velkou. Tu S02 zrovna ted v periheliu pozorujou pri rychlosti 2.5% c ... (a odpozorovali potvrdili na tom gravitacni redshift!!!
    ...titulek trochu keca, ty hvezdy obihaji malou cernou diru a az celej tenhle cluster obiha tu centralni.
    Ty dve neblizsi hvezdy S02 a S102 maji 11 a 15 let obeznou dobu!!!

    The 'air conditioners' that the Apollo astronauts were seen carrying with them to the transfer van during launch day were Portable Oxygen Ventilators. The POV's pre-oxygenated the astronaut and purged the nitrogen from their body, which was needed during altitude testing/training in the spacecraft as well as for launch to prevent 'the bends.' In addition to providing breathing oxygen, the POV kept the space suit pressurized, dehumidified and cooled as well as helped remove moisture from the body. There were different models of the POV, but they generally lasted approximately 30 minutes and after the astronaut was on his way in the transfer van to the launch pad, he would be connected to a fully charged POV and then eventually connected to the Command Modules suit circuit once inside the spacecraft. There was also an open-loop ventilator that was similar in operation to the POV, except used only for cooling when the helmets & gloves were off.
