At this extreme altitude gas molecules are widely separated. Above 60 miles (100 km) from Earth's surface the chemical composition of air becomes strongly dependent on altitude and the atmosphere becomes enriched with lighter gases (atomic oxygen, helium and hydrogen).
Here's a write-up on the topic: 'A Day When Everything Went Wrong'.
Explanation:
I woke up that morning, wondering why my alarm hadn't gone off. Just as I was lying in bed, my room looked brighter than usual - I glanced at the watch on my bedside table and it showed 8:30 am, a whole 90 minutes later than when I generally wake up! That meant I had barely 20 minutes to get ready and reach class.
Being late meant quickly washing my face and no breakfast. Once I reached class (hungry, disheveled and ten minutes late), the professor refused to let me in. That was like the icing on the cake. I sat morosely on the steps outside the classroom, waiting for the bell to signal the beginning of the next period, which was the chemistry lab (my favourite). Lo and behold, I opened my bag only to realize I had forgotten to pack my lab coat for the day! That would mean I would be denied entry to the lab too.
I trudged back home, feeling awful. Just as I was about to enter my gate, I tripped on an uneven stone lying on the pavement - and fell flat on my face. That was literally the last straw. Bleeding a little on my forehead, I entered my room and slammed the door, grumbling about the extremely horrid day that I had had and wondering what else was lying in store for me.
