The Lunar Reconnaissance Orbiter
camera provides a glimpse into

2
00:00:04.004 --> 00:00:08.141
our Moon's volcanically active
past. This is Rima Prinz - a

3
00:00:08.141 --> 00:00:11.078
long channel where lava once
flowed from the Vera volcanic

4
00:00:11.078 --> 00:00:14.581
depression. Within Vera,
eruptions of fiery lava

5
00:00:14.581 --> 00:00:17.918
fountains formed a lake of lava
three hundred meters deep and

6
00:00:17.918 --> 00:00:20.787
carved a lava channel a hundred
times deeper and ten times

7
00:00:20.787 --> 00:00:24.258
longer than ones on Earth. This
region shows that eruptions on

8
00:00:24.258 --> 00:00:29.029
the Moon were sometimes larger
than what we see on Earth today.
