SpaceX says Super Heavy is necessary to get the spacecraft out of Earth's gravity well with enough fuel to get where it's going. Starship can then travel to its destination (like Mars) and then launch itself back into space without Super Heavy, thanks to the lower gravity. Starship is ...

We can only settle the Moon or Mars if they have enough gravity for good long-term human health. And we don’t know if lunar or Martian gravity are enough! Astronauts lost that contest decades ago. And since then, robotic spacecraft have continued to evolve far faster than humans. Artific...
Type of transition used to edit two shots into one. Types of morphing. Morphing is mostly known as a visual effects technique in the film industry. It’s also used in other mediums such asanimationand 3D modelling. There are different approaches to morphing. ...
After riding in our spacecraft, we are arriving on Mars. What do you think we will see on Mars? Do you think we will find little green men? 1 Will there be any life at all on Mars?Mars is the only planet whose surface can be seen clearly from the Earth. It looks red because ...
There are two kinds of satellites: natural (such as the moon orbiting the Earth) or artificial (such as the International Space Station orbiting the Earth). There are dozens upon dozens of natural satellites in the solar system, with almost every planet having at least one moon. Saturn, for...

There are a few different types of digital twins. First, there’s a product twin, which is a representation of a product. This digital twin can include products at various stages of the life cycle, from initial concept design and engineering through full functionality—meaning you get live, ...
Spacecraft Does not require life support if unmanned. The spacecraft orbiting Jupiter is automated and operates remotely. 2 Spaceship Represents a subset of spacecraft. Spaceships are a crucial part of our expanding capabilities in manned spaceflight. 3 Spacecraft A spacecraft is a vehicle or mach...
