Stupni zavěšenému na jeřábu byly udělovány impulsy a pomocí senzorů byla sledována strukturální frekvenční odezva. Během zkoušky byly měřeny a zaznamenávány modální parametry odezvy konstrukce, jako frekvence, poměrný útlum a reziduum. Výsledkem zkoušky bude matematický popis dynamického chování konstrukce, tedy modálního modelu měřeného systému. Data o rezonanci stupně budou využita v navigačním softwaru rakety.
Prostě technik praštil kladivem do výtažného pavouku přišroubovanému k visícímu stupni. Později praštil i na jiných místech stupně.

Rozhodně se neoznačuju za znalce umění, takže to berte s rezervou, ale osobně považuju tenhle klip za pěknou práci - střih pěkně ladí s hudbou a kameraman si dal taky záležet.
Since the SLS Program was established 8 years ago, NASA and its supporting contractors have been
designing, building, and testing elements of its new heavy-lift rocket to support the Agency’s lunar and
Mars ambitions, including landing astronauts on the Moon’s south pole by 2024. Although many of the
significant technical challenges the Program has faced over the years, such as getting Michoud up and
running efficiently, propulsion insulation issues with the Boosters, and ECU for the RS-25 Adaptation
have been corrected, collectively, they have contributed to the Program’s significant cost increases and
schedule delays.
NASA’s continued struggle with managing SLS Program costs and schedule has the potential to impact
the Agency’s ambitious goals for the Artemis program. Furthermore, the SLS Program exceeded its ABC
by at least 33 percent at the end of FY 2019, over a year before the November 2020 scheduled launch
date for Artemis I, and consequently the Program will need to be rebaselined. Because the original
baseline only focused on Artemis I costs, almost $6 billion in SLS spending through FY 2020 is not
reflected in the Agency’s cost commitment. While we acknowledge that NASA does track total SLS
Program costs through its annual budget process, without transparent and accurate reporting on its cost
commitments it will be difficult for the Agency, Congress, and external stakeholders to make informed
decisions about the future of the human space flight program.
Technical and management problems have affected the building of SLS Core and Upper stages,
adaptation of the RS-25 Engines, and the building of the Boosters to meet SLS requirements. Looking
forward, the SLS Program faces the critical Green Run test of Core Stage 1, integration of all the SLS
elements, and integration of the SLS with the Orion capsule and service module. Since each of these are
first-time events, further delays in the current Artemis I launch date of November 2020 are likely.

Prosím, prosím:
Laiku, nemohl bys to alespoň shrnout v češtině nebo slovenštině?
