Rachete balistice Resboiul Stelelor

Satan ne-ar putea scapa de meteoriti

SS-18 Satan – R-36M2 Voyevoda ICBM

Rusia ar putea folosi rachete balistice intercontinentale tip SS-18 Satan, datand din era sovietica, pentru distrugerea corpurilor ceresti care ameninta planeta – a declarat zilele trecute un cercetator rus.

Declaratia vine la patru luni dupa ce un meteorit a lovit Rusia in regiunea Ural.

“Carrier rockets created on the basis of intercontinental ballistic missiles like Voyevoda [the Soviet name of Satan missiles], which use standard liquid fuel based on hydrazine, are well-suited for fighting suddenly discovered small [space] objects,”

A declarat Sabit Saitgarayev, cercetator in cadrul State Rocket Design Center din Miass, regiunea Chelyabinsk.

“They [missiles] can stay in the condition of their readiness for launch for ten and more years, after some reequipping,”

A mai spus cercetatorul, precizand mai apoi:

Cryogenic fuel used in Russian heavy space rockets Soyuz and Angara cannot be kept for long and is supplied directly before the launch. Several days are required for preparing these rockets for launch, which makes them unsuitable for destroying small space objects that can be discovered several hours before their collision with the Earth.

Pana aici, treaba e buna. Rusii ar putea astfel mentine la indemana un arsenal de rachete anti-meteorit… dar, cu precizia cum stam?

Acelasi Saitgarayev spune:

Satan missiles can be used for destroying small space objects with a diameter of up to 100 meters threatening the Earth, if the missile is equipped with the third stage. If reequipped with a booster, the missile will be able to destroy space objects five-six hours before their collision with the Earth.

Cat despre factorul timp, rusul aproximeaza:

The Satan missile can take off 10-20 minutes after an order for launch, the scientist said. If two hours are needed for the missile to reach the target, another two hours are required to specify the space object’s trajectory and one hour to coordinate the missile launch with the heads of other countries.

Nu-i rau deloc, este?

Si acum, sa ne reamintim bilantul: pe 15 Februarie, o unda de soc a lasat fara geamuri mii de cladiri in zona orasului Chelyabinsk – provocand desigur si alte stricaciuni, intre care 1200 raniti, dintre care 52 spitalizati.

Conform estimarilor NASA, meteoritul a avut circa 15 metri in diametru la momentul intrarii in atmosfera.

  • Am citit si articolul din RIA Novosti si totusi ceva nu e in regula. Un meteorit de “mici dimensiuni” avand diamtrul de 100 metri, ar avea o masa de 2 MILIOANE TONE ! Nici Scaraoschi in persoana nu i-ar veni de hac 🙂
    Meteoritul de la Celiabinsk a fost estimat ca avand un diametru intre 17 si 20 de metri. La un diametru de 18 metri si o densitate de 3.4 g/cm3 [1], rezulta o masa de 10400 tone, ce corespunde cu estimarea NASA.
    Conform [1] un asemenea meteorit va avea o viteza minima de 70% din viteza lui cosmica, scadere determinata de frecarea cu aerul. In cazul de fata, viteza initiala a fost estimata la 18.6 Km/s, deci va avea o viteza minima de 13 Km/s. Nu exista o racheta care sa poata lovi (deturna de la traiectorie) un asemenea bolid.
    Si atunci de unde un asemenea anunt ? Greseala gazetareasca de interpretare ?

    • Da asa este. Dar daca viteza cosmica initiala e mica,(nu toate obiectele cosmice au aceeasi viteza) atunci si impulsul e mai mic. O detonare linga asteroid (inainte sa intre in atmosfera) poate ca l-ar devia si i-ar schimba directia. Dar detonarile nucleare sunt interzise in cosmos prin tratat. Poate se fac presiuni pentru a elimina consecintele acestui tratat?
