Este post será uma actualização de um outro que coloquei em finais de Outubro, Ucrânia No Espaço: O Fim?, e que fala acerca dos problemas e dependências de projectos do sector espacial americano.
Na altura, conforme indiquei, o foguete que explodiu tinha um estágio de fabrico ucraniano e foi esse que deu problemas. O embaraçoso foi descobrir a dependência em recentes foguetes americanos de componentes do tempo da URSS.
Depois deste embaraço, a quem os americanos recorreram para solucionar o problema? Por mais incrível que pareça, e será algo que não será muito badalado concerteza por aí. Foram ter com os russos. Os tais que estão debaixo de duras sanções ocidentais, sanções em tudo, excepto em algumas coisas...
Antares Upgrade Will Use RD-181s In Direct Buy From Energomash
Orbital Sciences Corp. will buy directly from Russia’s NPO Energomash a new rocket engine with a long heritage, to replace the surplus Russian powerplants tentatively implicated in the Oct. 28 failure of an Antares launch vehicle with a load of cargo for the International Space Station (ISS).
Designated the RD-181, the new engine will be used on Antares in shipsets of two to accommodate as closely as possible the two-engine configuration built around the AJ-26 engines supplied by Aerojet Rocketdyne, Orbital Sciences managers said Dec. 16...
...Congressional concern about Russian aggression in the Crimean peninsula led to a ban in the new National Defense Authorization Act (NDAA) on using RD-180s purchased after Russia occupied the Ukrainian territory on Feb. 1. Grabe said that legislation will not affect the deal to buy RD-181s from Energomash.
“We’ve coordinated with all relevant congressional committee staffs to keep them informed of our decision,” Grabe said. ...
Um pormenor importante aqui, a Orbital Sciences Corp., comprou os motores russos RD-181, e os que foram sancionados foram os RD-180, e porque este modelo foi referido? por algo muito curioso, os satélites MILITARES americanos são colocados no espaço por foguetões que usam os motores RD-180 russos e isto é algo que os preocupam, esta enorme dependência de material russo, em várias áreas do sector espacial americano.
Após sanções, a Rússia continua a enviar os motores para os EUA, para estes poderem colocar os seus satélites militares no espaço, conforme atesta este artigo:
Russian RD-180 rocket engines delivered to ULA
Dodging tit-for-tat sanctions that have paralyzed trade between the United States and Russia, a cargo plane landed in Alabama on Wednesday with two Russian-made RD-180 engines destined to power U.S. government spacecraft into orbit aboard Atlas 5 rockets.
The engines flew from Moscow to Huntsville, Ala., aboard a Russian Antonov An-124 transport plane. Workers planned to unload the engines for a road trip to United Launch Alliance's rocket factory in nearby Decatur, Ala.
The shipment marked the first time RD-180 engines were delivered to the United States since a senior Russian government official threatened to cut off the supply of engines for launches for the U.S. military, the primary customer for United Launch Alliance's Atlas 5 rocket.
