Falcon 9 is a two-stage-to-orbit medium lift launch vehicle designed and manufactured by SpaceX in the United States. It is powered by Merlin engines, also developed by SpaceX, burning liquid oxygen (LOX) and rocket-grade kerosene (RP-1) propellants. Its name is derived from the Millennium Falcon and the nine engines of the rocket’s first stage. The rocket evolved with versions v1. 0 (2010–2013), v1. 1 (2013–2016), v1. 2 “Full Thrust” (2015–2018), and its Block 5 variant, flying since May 2018. Unlike most rockets, which are expendable launch systems, Falcon 9 is partially reusable, with the first stage capable of re-entering the atmosphere and landing back vertically after separating from the second stage. This feat was achieved for the first time on flight 20 with the v1. 2 version in December 2015.
The existence of such powerful roaring winds kicking up violent and powerful dust storms suggests that the underlying sand can be set in motion, too, and that the giant dunes covering Titan's equatorial regions are still active and continually changing.
Phases of the Moon. The moon cycles 13 times a year through phases, each of which influence us just like the pull of the tides. It starts with the New Moon, which carries the energy of new beginnings, this is a great time to focus on stepping into something new. Then the Full Moon, Signifies the time of the completion of a project, and finally returns to the New Moon again. This entire cycle occurs over a period of 28 days, and yes, there is no mistaking it, this is the same as women's menstrual cycles, women tend to be much more connected to the moon than men.
The team of scientists used data gathered by NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission, composed of a duo of twin spacecraft that circled Earth's Moon throughout 2012, each measuring the push and pull of the other as an indicator of lunar gravity.
