Olympus Mons

• Dalam studi yang dilakukan oleh misi Mariner 9 NASA, gunung berapi tersebut mengungkapkan lingkaran cahaya yang memanjang ratusan kilometer di dasarnya;
• Gambar-gambar baru membawa rincian Lycus Sulci, formasi yang ada di batas halo;
• Lingkaran cahaya ini menunjukkan runtuhnya sisi bawah gunung berapi 100 juta tahun lalu;
• Aliran lava besar turun melalui Olympus Mons dan menyebabkan bebatuan jatuh ke bagian bawahnya, yang berisi es dan air;
• Lava panas itu melelehkan es, sehingga menjadi tidak stabil;
• Tepian gunung berapi yang berbatu-batu pecah, sebagian tergelincir;
• Keruntuhan terjadi dengan batu-batu besar yang tersebar di dataran terdekat;
• Longsor tersebut menyebabkan perubahan relief Mars, karena bagian daratannya menyebar, terkompresi dan terpisah;
• Saya senang menunjukkan kepada Anda foto-foto baru Lycus Sulci.

Peristiwa serupa bisa kita lihat di Bumi, seperti di pulau vulkanik Hawaii dan Kepulauan Canary.

Penelitian baru menemukan bahwa kolonisasi awal Mars bisa dimulai hanya dengan 22 orang, jumlah yang jauh lebih kecil dari perkiraan penelitian sebelumnya. Lebih lanjut, para peneliti juga menyarankan tipe kepribadian yang memungkinkan koloni tersebut bertahan dalam jangka panjang.
