As tecnologias mais estratégicas de uma nação são as chamadas tecnologias duais. Estas tecnologias podem ser usadas para fins civis e militares. A Astronáutica é essencialmente uma tecnologia dual, nascida durante a guerra fria. Um foguete pode botar um satélite em órbita, mas, com mínimas mudanças estruturais, pode pôr uma ogiva nuclear no centro do território de qualquer país. Por isso, a transferência deste tipo de tecnologia é tão restrita. Tudo que se relaciona ao espaço é caro, arriscado e sigiloso.
Outro aspecto interessante da Astronáutica é o seu caráter interdisciplinar. Para pôr um satélite em órbita, não basta conhecer as leis da mecânica newtoniana. Um foguete é um prodígio de engenharia, onde ligas metálicas leves e resistentes envolvem substâncias químicas instáveis, explosivas e, às vezes, corrosivas. Se o voo é tripulado, a logística é ainda mais complexa, já que seres humanos estão envolvidos. Levar astronautas ao espaço implica levar, também, todo um ambiente propício à vida: ar, água e alimento. Isso somente para falar no bem-estar físico dos astronautas. Cuidar da saúde mental dos astronautas também é um desafio e tanto.
Por tudo isso, eu adoro ensinar Astronáutica aqui no Planetário. Neste mês eu enfrento de novo o agradável desafio de falar sobre as barreiras espaciais superadas pela humanidade. Mas não reclamo. É muito estimulante lidar com tantos temas fascinantes. Como diria Buzz Lightyear, meu personagem preferido de Toy Story: “Ao infinito… e além”.
I hurried into the local department store to grab1 some last minute Chirsmas gifts. I looked 70-697 test at all the people 300-101 Dump and grumbled2 to myself. I Examprepwell would be in here forever and I just had so much to do. Chirsmas was beginning 70-697 test to become such a drag. I kinda wished 300-070 exam dumps that I could just Learningpdf sleep through 70-697 test Chirsmas. But I hurried the best I could through all the people to the toy department. Learningpdf Once again I kind of mumbled3 to myself at the prices of all these toys, and wondered 300-101 Dump if the grandkids would even play whit4 them. I found myself in the doll aisle5. Out of the corner of my eye I saw a little boy about 5 holding a lovely doll.He 300-101 Dump kept touching6 her hair and he held her so gently. I could 70-697 test not Examprepwell seem to help myself. I just kept loking over at the little boy and wondered 300-070 exam dumps who the doll was for. I Examprepwell watched him turn to a woman and he called his aunt by name and said, “Are you sure I don’t have enough money?” She replied a bit impatiently, “You know that you don’t 300-101 Dump have enough money for Examprepwell Learningpdf it.” The aunt told the little boy not to go anywhere that she had 300-070 exam dumps to go and get some other things and would be back in a few minutes. 300-070 exam dumps And then she left Examprepwell the Learningpdf aisle. The boy continued to hold the doll. After a 300-070 exam dumps bit I 300-070 exam dumps asked 300-070 exam dumps the boy 300-101 Dump who the doll was 70-697 test for. He said, “It is the doll my sister 300-070 exam dumps wanted so badly for Chirsmas. 300-101 Dump She Learningpdf 300-070 exam dumps just knew that Santa would bring it. “I told him that maybe Santa was going 300-101 Dump Examprepwell to bring it . He said, “No, Santa can’t go Learningpdf Learningpdf where my sister is…. I have to give the doll to my 300-070 exam dumps Mama to take to Examprepwell her. “I Learningpdf asked him where his siter was. He looked at Learningpdf 300-101 Dump me with the saddest eyes and said, “She was Examprepwell gone to be with Jesus.
My Daddy says that Mamma is going to have to go 300-101 Dump be with her.” My heart Learningpdf nearly stopped beating. Then the boy looked at me again and said, “I told my Daddy to tell Learningpdf my Learningpdf Mama not to go 70-697 test yet. I told him to tell her to wait till I got back from the store.” Then he asked me if i wanted to see his picture. I told him I’d love to. He pulled out some picture he’d had taken at the front of the store. He said, “I want Examprepwell my Mama to take this with her so the dosen’t ever forget me. I love my Mama so very 70-697 test much and I wish she dind not have to leave 70-697 test me.But Daddy says she will need to be with 70-697 test my sister.” I saw that the little boy had lowered his head and had grown 70-697 test so qiuet. While 70-697 test 300-070 exam dumps he was not looking I reached into my purse and pilled out a handful of 300-101 Dump bills. I asked the Examprepwell little boy, “Shall we count that miney one Learningpdf more time?” He grew excited and said, “Yes,I just know Examprepwell it has to be 70-697 test Examprepwell enough.” So I slipped my money in with his and we began 70-697 test to count it . Of course it 300-070 exam dumps was plenty for 70-697 test the doll. He softly 300-070 exam dumps said, “Thank you Jesus for giving 300-101 Dump me enough money.” Then 300-101 Dump the boy said, “I just asked Jesus to give me enough money to buy this doll so Mama can take it with her to give my sister. And 300-070 exam dumps he 300-101 Dump heard my prayer. I Examprepwell wanted to ask him give for enough to buy my Mama a white rose, but I didn’t ask him, but he gave me Examprepwell enough to buy the doll and a rose for my Mama. She loves Learningpdf white rose so much. “In Learningpdf a few minutes the aunt came back and I wheeled my cart Learningpdf away. I could not keep from thinking about the little boy as I finished my shoppong in a ttally different spirit than when Examprepwell 300-070 exam dumps I had 70-697 test started. And I kept remembering a story I had seen in the newspaper several days earlier about a drunk driver hitting a car and killing7 300-070 exam dumps a little girl and the Mother was in serious condition. The family was deciding on whether to remove the life support. Now surely this little boy did not belong with that story.Two days later I read in the paper where the family had disconnected the life support and the young woman had died. I could not 70-697 test forget the little boy and just kept wondering if the two were somehow connected. Later that day, I could not help myself and I went out and bought 300-101 Dump aome white roses and took them to the funeral home where 300-101 Dump the yough woman was .And there she was holding a lovely white rose, the 300-101 Dump beautiful doll, and the picture Examprepwell of the little boy in the store. I left there in tears, thier life changed forever. The love that little boy had for his little sisiter and his mother was overwhel. And in a split8 second a drunk driver had ripped9 the life of that little boy to pieces.
