The Earth has always been in danger because of the fall of foreign bodies from the sky.The aim of the research was to find the way from possible impacts with foreign bodies.
The scientific articles of Henry Gatsby, Master of Scott College, has been thoroughly analyzed about researches of the fall of foreign bodies on our planet (meteorites and asteroids) and especially the article about impacts of the meteors on the ground occurred in the following years: 1938-1980-1992-1994-1995-2013.The first idea was to project a “space dome” which could protect our planet. But immediately the first problems came out, for example, the fact that the dome would have to be transparent, otherwise it wouldn’t filter sunlight, but the only transparent material which the research group thought was the glass which however would be too fragile to hold the impact with an asteroid or a meteorite. Another problem was the maintenance of the dome which would be constantly in motion with the Earth and its orbit so that it could not collide with our planet. Another hypothesis was to send in the space some satellites that would orbit around the planet which would always keep the space surrounding the Earth under control.

Once found out the risks and the localization of the possible impact, scientists considered the importance of the use of some rockets capable of exploding the asteroid before entering in the atmosphere or, at least, diverting it in order to avoid the impact with our planet. Starting from these two possible solutions for the problem, it was essential to understand the damages the asteroid would cause and the possibility of further damages. In order to understand this possibility some experiments were carried out.

From these scientific values we can note that the biggest is a foreign body the greatest are the damages produced by the impact on the ground.
We wish we could finish this project if there were more funds and a highly qualified staff to face any technical problem.

La Terra è sempre stata in pericolo a causa della caduta di corpi estranei.L’obiettivo della ricerca era trovare il modo di proteggere la Terra da eventuali impatti con corpi estranei.
Sono stati analizzati a fondo gli articoli scientifici riguardanti ricerche sulla la caduta di corpi estranei sul nostro pianeta (meteore e asteroidi) e in particolare l’articolo diHenry Gatsby dello Scott College: riguardante le collisioni tra le meteore e il suolo avvenuti nei seguenti anni: 2013-1995-1994-1992-1980-1938.La prima idea era stata quella di progettare una “cupola spaziale” in grado di proteggere il pianeta. Però subito sono sorti i primi problemi, ad esempio, il fatto che lacupola sarebbe dovuta essere trasparente altrimenti non sarebbe filtrata la luce, ma l’unico materiale trasparente a cui il gruppo di ricerca a pensato era il vetro cheperò sarebbe stato troppo fragile per reggere l’impatto con un asteroide o un meteorite; un altro problema era il mantenimento della cupola che doveva esserecostantemente in movimento con la Terra e il suo mantenimento in orbita doveva essere tale in modo da non farla collidere con il pianeta. Un’altra ipotesi era quella dispedire nello spazio dei satelliti che orbitassero intorno al pianeta in modo da tenere sempre sotto controllo lo spazio circostante la Terra. Una volta spediti nello spazio,i satelliti avrebbero dovuto emettere un segnale d’allarme ad una base sulla terraferma adibita a captare questo segnale in caso di rischio di collisione con il pianeta daparte di un meteorite o un asteroide. Una volta captato l’allarme e accertato il rischi e la localizzazione del possibile impatto, sarebbero dovuti essere lanciati in orbitadei razzi o dei missili in grado di far esplodere l’asteroide prima della sua entrata nell’atmosfera o, per almeno, di deviarlo in modo da evitare l’impatto con il pianeta.Partendo da queste due possibili soluzioni al problema bisognava capire in base a quali parametri l’asteroide avrebbe causato più danni e per capirlo sono stati effettuatidegli esperimenti.
Altezza Diametro Profondità Oggetto
150 cm 5,5 cm 2,5 cm pallina blu
150 cm 10,5 cm 3,0 cm arancia
150 cm 3,0 cm 0,7 cm pallina bianca
150 cm 11,3 cm 2,2 cm mandarino
Da questi valori possiamo notare che maggiori sono le dimensioni del corpo estraneo, maggiori sono i danni provocati dall’impatto con il suolo.
Per portare a termine questo progetto bisognerebbe avere a disposizione un quantitativo notevole di fondi e uno staff di persone altamente qualificate in grado di far fronte a qualsiasi problematica di tipo tecnico.
Organizzazione Esperimento•Far cadere da una determinata altezza degli oggetti di formasferica, o approssimativamente sferica (simulazione di meteoriti),con diversa densità e di diverso volume.•Utilizzare scatole di cartone contenenti della farina (simulazionedella superficie terrestre) per osservare il cratere prodottodall’impatto.•Misurare le dimensioni (larghezza e profondità) del crateregeneratosi dall’impatto utilizzando un righello con sensibilità pariad un millimetro.
