Explaining The Universe on Instagram: "Spacecraft can use the gravity of planets or moons to change their velocity and direction through a technique called a gravity assist or gravitational slingshot. This method takes advantage of the motion and gravitational pull of a celestial body to boost or alter a spacecraft’s path without using extra fuel. When a spacecraft flies close to a planet or moon, it is pulled by the body’s gravity, gaining speed as it falls toward it and losing speed as it move

Explaining The Universe on Instagram: "About 4.5 billion years ago, during the chaotic early days of the solar system, a Mars-sized protoplanet named Theia is believed to have collided with the young Earth. This catastrophic impact released unimaginable energy, melting both worlds and blasting huge amounts of debris into space. The collision destroyed the early Earth’s original surface, reshaping the planet and forming a new, molten world. Much of Theia’s material merged with Earth’s core and ma

Our Third Dimension | Space Science Universe on Instagram: "Which planet represents you?😄😵‍💫 Info: Mercury’s axis tilt is almost zero at 0.01°, and it rotates once every 58.7 Earth days at about 10 km/h. Venus rotates backwards compared to most planets, with a tilt of 177° and a slow rotation taking 243 Earth days. Earth spins once every 23 hours and 56 minutes with a tilt of 23.44°, rotating around 1,574 km/h. Mars has a 25.19° tilt and rotates in 24 hours and 37 minutes at 866 km/h. Jupiter
