SOLAR SYSTEM

Detailed explanation-1: -The Short Answer: Spacecraft send information and pictures back to Earth using the Deep Space Network (DSN), a collection of big radio antennas. The antennas also receive details about where the spacecraft are and how they are doing. NASA also uses the DSN to send lists of instructions to the spacecraft.

Detailed explanation-2: -A space probe is an unpiloted, unmanned device sent to explore space and gather scientific information. A space probe is launched from Earth with a set of scientific instruments and tools used to study the atmosphere and composition of space and other planets, moons, or celestial bodies.

Detailed explanation-3: -Spacecrafts must provide their passengers with oxygen to breathe. Spacecrafts carry their own sources of oxygen and nitrogen. These gases are circulated throughout the spacecraft to provide similar air to the one we breathe on Earth. Astronauts must also carry their entire food supply when they travel to space.

Detailed explanation-4: -The space station has an internal pressurized volume equal that of a Boeing 747. More than 50 computers control the systems on the space station. More than 3 million lines of software code on the ground support more than 1.5 million lines of flight software code.

Detailed explanation-5: -Probes are a type of satellite. Instead of orbiting a planet as satellites do, probes travel through space and may carry telescopes and other instruments to study space objects such as planets, moons, asteroids, comets, and the Sun.

Detailed explanation-6: -While wearing the current space suits, astronauts wear a Communications Carrier Assembly (CCA), or “Snoopy Cap”-a fabric hat fitted with microphones in the ear area for listening and boom microphones in front of the mouth for speaking.
