By April 2011, the capabilities and performance of the Falcon 9 vehicle were better understood, SpaceX having completed two successful demonstration missions to LEO, one of which included reignition of the second-stage engine. At a press conference at the National Press Club in Washington, DC. on April 5, 2011, Musk stated that Falcon Heavy would “carry more payload to orbit or escape velocity than any vehicle in history, apart from the Saturn V Moon rocket . . . and Soviet Energia rocket”. In the same year, with the expected increase in demand for both variants, SpaceX announced plans to expand manufacturing capacity “as we build towards the capability of producing a Falcon 9 first stage or Falcon Heavy side booster every week and an upper stage every two weeks”.
These icy moon-worlds are the next important step in the scientific quest for the Holy Grail of life beyond our own planet. It is a strange era in human history. Astronomers have collected large amounts of data revealing bewitching clues that habitable ocean moon-worlds may be out there, within the family of our very own Star. Humanity is poised at the beginning of a new era. Sophisticated new technology might very soon answer the profound, and very ancient question, "Are we alone?"
We live in a Cosmic "shooting gallery". Objects inhabiting our Solar System have been profusely and mercilessly blasted by showering asteroids and comets for billions and billions of years. However, planets and large moons have their way of smoothing away the scars--their strong gravity pulls them into a nice ball-like spherical shape. Furthermore, some of these larger spheres possess sufficient internal heat to cause flows of fiery lava and other volcanic features that can fill in the scars of impact craters. A few such large bodies are blasted by strong winds and pouring rains, which also erode away the pockmarks left on their surfaces by showering impactors.
Jupiter is the fifth planet from our Star, the Sun, and it is more than twice as massive as all of the seven other major planets combined! Its immense mass weighs-in at an incredible 318 times that of the Earth.
