The lunar 🌙 base would be established through three phases, each of these three phases would cost on the order of $10 billion. The first of these, running through 📆 2028, is estimated to comprise 21 landings, putting a total of 4 metric tons of payload on the #Moon. Phase two, running from 2029 to 2032, is projected to entail 27 landings with a total mass of 60 metric tons. The final phase, from 2032 to 2036, will establish #habitats for long-term human 🧑‍🚀 presence

How is the Moon 🌙 1% of Earth’s 🌏 mass, but its #gravity is 17% of Earth’s ? https://www.astronomy.com/science/how-are-mass-and-gravity-correlated/

The moon's density is 3.34 grams per cubic centimeter (3.34 g/cm3). That is about 60% 📊 of Earth's density https://www.space.com/18135-how-big-is-the-moon.html

How is the Moon 1% of Earth’s mass, but its gravity is 17% of Earth’s?

When it comes to surface gravity, mass does matter, but so, too, does size. This means the Moon can punch above its mass.
