Mempersiapkan Penjelajahan Ke Luar Angkasa, Dari Bumi

Untuk melakukan penjelajahan di bumi, faktor-faktor seperti arah, posisi, dan cuaca merupakan faktor yang penting saat mempersiapkan perjalanan. Dengan menggunakan sistem navigasi dan peta, serta ramalan cuaca yang akurat hingga 2 derajat per harinya[1], kita dapat mempersiapkan rute perjalanan kita untuk mendatangi lokasi yang kita inginkan di permukaan bumi, dalam kondisi perjalanan yang terbaik. Di bumi saja, kita terbiasa untuk mempersiapkan perjalanan kita, untuk melakukan penjelajahan ke luar angkasa, di tata surya kita, bahkan di alam semesta, dunia yang misterius dan jauh berbeda kondisinya dengan bumi kita, tentu jauh lebih banyak data dan persiapan yang dibutuhkan.
