The #MarsHelicopter is gearing up for Flight 12. It’ll take place no earlier than Aug. 16, and will scout the intriguing “South Séítah” region. It'll aid @NASAPersevere scientists in determining which geologic features may be worthy of further scrutiny. https://t.co/9U7jRYpWBC https://t.co/FLYJWbEyEQ

Question about moon behavior on my fictional planet
So I'm writing a fantasy novel based on a fictional planet. This planet has two moons, and they play an important role in the story. One of the two moons acts similar to our Earth's moon (same rotation, same translation, same phases, etc). The second moon is kinda special: this moon orbitates very fast and does it in the opposite direction the planet rotates. This makes the moon behave in a way that it rises, crosses the sky, and sets within a span of 30 minutes; then stays hidden for 3 hours and then it rises again. So my question is: during those 30 minutes while the moon is crossing the sky, would it gradually change its phase? For example, would it rise while on waxing crescent and set on waxing gibbous? Thank you!

Methane is a potent greenhouse gas that can come from a variety of sources on our planet. @NASAEarth scientists study the global methane budget to better understand the primary sources of methane emissions and how they contribute to climate change: https://t.co/VWdVSdiWok https://t.co/ENVSVhsEFo
