Ode. Sad još 29 dana do sledeće kritične tačke...

[burekdzija]

Preziveo je lansiranje, sad korak po korak.

 

Koliko sam video, bice jos dosta kriticnih tacaka i na putu jer ce se postepeno razmotavati dok ne stigne.

 

A i ako se sjebe nesto, poslace satl u L2 da opravi. Not.

Odlična im ova stranica:

Danas gledao lansiranje sa bratom. On je inzenjer vazduhoplovstva i iako nikad nije radio posao za koji se skolovao, dok je studirao imao je jedan rad na motoru Ariane 5 (Vulcain). Zamalo suzu nije ispustio. 

 

Nadam se da ce sledeci kriticni momenti dobro proci.

Nego mene kopka da li su koristili log4j…

 

Edit: povlacim ovu neduhovitost za log4j posto vidim da koriste js (navodno) kao dsl za izdavanje komandi. Bice dakle nan-ova u izobilju.

NASA is taking a break in the deployment of the James Webb Space Telescope after successfully extending booms for the spacecraft’s sunshield.

 

NASA said Jan. 1 it would wait a day before beginning the process of tensioning the five-layer sunshield, getting it into its final form and ensuring the layers are separated from each other. That effort was originally rescheduled for Jan. 2, but NASA later said it was further delaying the start of the tensioning by an additional day to spend time “optimizing Webb’s power systems while learning more about how the observatory behaves in space.” The tensioning process is now scheduled to start no earlier than Jan. 3 and will take at least two days to complete.

 

Spacecraft managers added the pause in the sunshield deployment after working late into the night Dec. 31 to extend two “mid-boom” structures on either side of the spacecraft. Those booms extended the sunshield to its full size. That process started late when sensors indicated that a sunshield cover had not fully rolled up. Controllers decided to go ahead with the deployment of the booms because other data, including from temperature sensors and gyroscopes, were consistent with the removal of the cover.

 

“The team did what we had rehearsed for this kind of situation: stop, assess and move forward methodically with a plan,” said Keith Parrish, JWST observatory manager at the Goddard Space Flight Center, in a Dec. 31 statement. “We still have a long way to go with this whole deployment process.”
