LRO stands for Lunar Reconnaissance Orbiter. It is a robotic spacecraft that is orbiting, or flying around, the moon. It is taking pictures and gathering information about the moon’s surface. LRO has six different science instruments, including telescopes, sensors, lasers and detectors. These instruments will gather more information about the moon then we would had…

The Saturn V was a rocket NASA built to send people to the moon. The Saturn V was a type of rocket called a Heavy Lift Vehicle. This means it was very powerful. The Saturn V was the most powerful rocket that had ever flown successfully. The Saturn V was used in the Apollo program…

The Soyuz is a Russian spacecraft. Astronauts and cosmonauts travel to the International Space Station on the Soyuz. The Soyuz launches from the Baikonur Cosmodrome. It is located in Kazakhstan, a country on Russia’s southern border. The Soyuz transports crews to the International Space Station and returns them to Earth after their missions.The crew rides…

Before we start, we have a new member! His name is Raj and he originally wrote this post. Thanks. The International Space Station is a large spacecraft in orbit around Earth. It serves as a home where crews of astronauts and cosmonauts live. The space station also serves as a unique science lavatory. The first…

The Heavy Lift Launch System or I will call the HLLS, is a special rocket which has a job to carry payloads of any size. As everyone may know, rockets are different from one another. Also, HLL’s are the most powerful rockets. For example, the Saturn V rocket which carried men to the moon. Weighing…

The Hubble Space Telescope is a large telescope around Earth’s orbit. On April 24, 1990, it was launched by Space Shuttle Discovery. It orbits around 340 miles from Earths surface. It is 40 ft long and weighs about 2 elephants. Fun Fact: Hubble travels Earth about 5 miles per second and is solar powered Hubble…

NASA’s Parker Solar Probe will be the first object to “touch” the Sun. The probe was launched on August 12, 2018 on the Delta IV. Because the probe will be going so close to the star (approximately 3.8 million miles from the corona), it will need a very strong heat shield. The heat shield is…

The rocket propulsion system is all the parts making up the rocket engine. That includes the pumps, rocket nozzle, fuel, oxidizer, propellants and many more things. The propulsion system is what gives the rocket thrust. Thrust is the force of the rocket to move. Learn more about how a rocket works here.

Before we learn about rockets, we have to know what rocket science is. Rocket Science is the study of rockets and their design. A few jobs you can work with when you have a degree in rocket science is NASA and SpaceX. In these jobs, you have to do many calculations, plan trajectories, make rocket…

Our Solar System and several other systems are contained in the Milky Way (Our Galaxy). The Milky Way gets its name from how it looks from Earth. A band of light of stars. It has around 250 billion stars considering its radius of more than 52,850 light years. At the center of our galaxy, we…
