"La realizzazione e il lancio nello spazio di satelliti o sonde attraverso missili o navette spaziali sono un esempio di attività industriale di enorme complessità e di lungo periodo. Lo sviluppo di un programma spaziale prevede la realizzazione di vari sistemi costituenti: il segmento spaziale, cioè i lanciatori per l’accesso allo Spazio, i satelliti o le sonde, le infrastrutture spaziali abitate da astronauti oppure robotizzate; e il segmento di terra che consente agli operatori sulla terra di controllare i sistemi nello spazio e di fruire delle applicazioni derivanti dal loro uso.Il settore è di per sé peculiare dato l’ambiente extra-atmosferico ove si troveranno ad operare astronauti o sonde robotizzate, pertanto la manifattura dei sistemi spaziali è una pratica a metà strada tra la scienza esatta e l’artigianato di elevatissima qualità.Le metodologie e i processi realizzativi dei programmi spaziali hanno però avuto il pregio nel passato di costituire, sin dagli anni ’60, un modello di riferimento per altri settori industriali proprio a causa della loro unicità tecnologica e produttiva. E oggi le metodologie di gestione dei programmi spaziali sono standardizzate e consolidate.Gli elementi trattati in questo libro intendono avvicinareil lettore alle specificità gestionali della concezione, del finanziamento e della messa in essere di un programma spaziale, una tra le più complesse attività umane influenzate da fattori storici, scientifici, economici e politici."

"This book shows step-by-step examples of the physical arguments and the resulting calculations obtained using the quick-fire method. Also demonstrate the estimation improvements that can be obtained through the use of more detailed physics-based back-of-the-envelope engineering models. These different methods are used to obtain the solutions to a number of design and performance estimation problems arising from two of the most complex real-world engineering projects : the space shuttle and the hubble space telescope satellite."

"Emigrating beyond earth puts space colonization into the context of human evolution. Rather than focusing on the technologies and strategies needed to colonize space, the authors examine the human and societal reasons for space colonization. They make space colonization seems like a natural step by demonstrating that if will continue the human species' 4 million-year-old legacy of adaptation to difficult new environments. The authors present many examples from the history of human expansion into new environments, including two amazing tales of human colonization, the prehistoric settlement of the upper Arctic around 5,000 years ago and the colonization of the Pacific islands around 3,000 years ago, which show that space exploration is no more about rockets and robots that Arctic exploration was about boating!"

"The book describes the recent trends in space policy and the space sector overall. While maintaining a global scope with a European perspective, it links space policy with other policy areas, highlights major events, and provides insights on the latest data. The Yearbook includes the proceedings of ESPIs 12th Autumn Conference, which discussed the growing importance of Security in Outer Space and the stakes for civilian space programmes in the public and private sectors. Bringing together satellite operators, SMEs, European and American institutions, and think tanks, the Autumn Conference served as platform for fresh insights on security in outer space and the potential of transatlantic relations to address its challenges. The Yearbook also includes executive summaries of ESPI's work in 2017 as well as ESPIs 2017 Executive Briefs, covering topics such as suborbital spaceflight, super heavy lift launch vehicles, collaboration with China, and the delimitation of outer space."

"Salah satu isu lingkungan hidup yang memberikan pengaruh signifikan terhadap semua komponen kehidupan dan sistem kehidupan banyak kalangan saat ini adalah mengenai fenomena perubahan iklim (climate change). Perubahan Iklim tidak hanya berdampak di permukaan bumi saja, namun dampak Perubahan Iklim juga menjadi masalah di lingkungan antariksa, hal ini disebabkan aktifitas manusia seperti pembakaran fosil, kegiatan industri, dan penggunaan lahan secara eksploitatif telah berkontribusi dalam peningkatan konsentrasi karbon dioksida (CO2) dan zat sejenis lainnya seperti methane (CH4), yang pada akhirnya akan berujung pada peningkatan suhu global secara keseluruhan. proses tersebut mengakibatkan peningkatan konsentrasi Karbondioksida (CO2) dan Methana (CH4) di atmosfer bawah (terjadi pemanasan atmosfer bawah) yang menyebabkan pendinginan atmosfer atas yang berdampak menurunkan kerapatan atmosfer atas tempat satelit-satelit LEO berada (Satelit di Orbit menengah bumi). Karena ada indikasi kecenderungan penurunan kerapatan atmosfer atas, maka debris dan satelit-satelit akan semakin lama berada di orbitnya.Tujuan penelitian ini adalah untuk menganalisis Potensi ancaman Sampah Antariksa terhadap Keamanan Nasional dan Peran Kelembagaan LAPAN dalam Mitigasi Ancaman Keamanan Nasional dalam Bidang Keantariksaan terkait dampak dari Perubahan Iklim. Metoda yang digunakan dalam penelitian ini adalah deskriptif, dan hasil dari analisis yang diperoleh adalah Bagi Indonesia, isu sampah antariksa tergolong krusial karena dua alasan, Pertama ukuran negara dan populasi yang besar dan yang kedua perkembangan jumlah/populasi sampah antariksa yang semakin bertambah, salah satunya adalah Praktik RPO sebagai misi rawan, Terkait Panduan Mitigasi sampah antariksa untuk saat ini LAPAN belum membuat panduan tersebut tetapi LAPAN sudah melakukan Mitigasi Benda jatuh antariksa sebagai bagian dari sampah antariksa. LAPAN telah melakukan pengamatan dengan Sistem/program tracking sampah antariksa dengan menggunakan kode pemodelan prediksi dari CELESTRAC. Pemantauan ini dilakukan dengan memanfaatkan data orbit satelit yang saat ini dipublikasikan oleh USSPACECOM. Walaupun demikian ternyata di lapangan dalam melakukan pengamatan dan pemodelan yang bergantung dari data orbit negara lain masih banyak memiliki kekurangan.

One environmental issue that has significant impact on all components of life and the lives of many systems today is the phenomenon of climate change (climate change). Climate change not only impacts on the earth's surface, but the impact of climate change is also an issue in the space environment, this is due to human activities such as burning fossil, industrial activities, and exploitative land use has contributed to the increase in the concentration of carbon dioxide (CO2) and substance other such as methane (CH4), which in turn will lead to an overall increase in global temperatures. The process resulted in an increase in the concentration of carbon dioxide (CO2) and Methane (CH4) in the lower atmosphere (atmospheric warming below) which cause cooling of the upper atmosphere that impact on reducing the density of the upper atmosphere where satellites are LEO (satellites in medium earth orbit). Because there is an indication of the downward trend in the density of the upper atmosphere, the debris and satellites will longer be in orbit.

The purpose of this study was to analyze the potential threat to the National Security Space Trash and Space agency Institutional Role in National Security Threat Mitigation in a field related to the impact of Keantariksaan Climate Change. The method used in this study is descriptive, and the results obtained from the analysis is For Indonesia, the issue of space junk classified crucial for two reasons, first the size of the country and the large population growth and the second number / population growing space debris, one of which Practice RPO is as mission-prone, manual Mitigation Related to the current space debris space agency has not made the guide but did Mitigation space agency already falling object space as part of the space debris. Space agency has made observations with the system / program tracking space debris using predictive modeling code of CELESTRAC. Monitoring is done by utilizing the satellite orbit data is currently published by USSPACECOM However it turns out in the field making observations and modeling that relies on the orbital data of other countries still have many shortcomings."
