    Now that NASA’s James Webb Space Telescope has been assembled into its final form, testing teams seized the unique opportunity to perform a critical software and electrical analysis on the entire observatory as a single, fully connected vehicle.

    Known as a Comprehensive Systems Test or CST, this was the first full systems evaluation that has ever been run on the assembled observatory, and one of the final first-time activities the team will perform. Similar performance evaluations have been completed in Webb’s history, using simulations and surrogates to infer data about pieces of the spacecraft that had not yet been assembled. Now that Webb is fully built, simulations and simulators are no longer needed, and engineers can confidently assess both its software and electronic performance.

    V Moskvě byl zadržen poradce šéfa ruské kosmické agentury Roskosmos, bývalý novinář Ivan Safronov. Je podezřelý z vlastizrady. (Roskosmos)

    Podle https://www.swissinfo.ch/...of-russian-space-agency-detained-on-treason-charges---roscosmos/45885766 ale It said the detention of Ivan Safronov, a former journalist specialising in military affairs, was not linked to his work with the space agency where he has worked as an advisor to General Director Dmitry Rogozin.

    Scott Manley to pitvá na svém twitteru celý den. Baterie (3ks celkem na 2nd stage) dávají 100kW do turbopumpy. Zmáknout swap (přechod na 3., odhození vyobrazeného páru) bez poklesu výkonu bude dost klíčové tajemství Rocket Labu.
    Jedna věc je řízeně přiškrtit výkon, druhá když to zasambuje samo. Proto mě hned zajímalo, co se děje v komoře.

    KULA: tak i podle drbu nastava staging baterii az po 6. minute, tedy problem nastal kdyz jeste stale pouzivali stare baterie

    KULA: prepnou napajeni na posledni baterii. Zkontroluji, ze uz zadny proud z tech dvou, do ted pouzivanych, baterrii neproudi. Provedou odpojeni a odhodi je.
    Je to sice unikum rakety Elektron, ale to mne prijde, ze je pravdepodobnejsi, ze selhala navigace, resp. regulace tahu, to jsou o mnoho konplexnejsi systemy. Vsak uvidime.
