What is the biggest satellite in space?

How many planes are in space?
Since these two planes do not have parallel normal vectors, the planes must intersect, and thus must intersect in a line. Observe that the line of intersection lies in both planes, and thus the direction vector of the line must be perpendicular to each of the respective normal vectors of the two planes.
How satellites improve your life?
Satellite data can be used in many ways: it allows us to analyse weather from space, see changes in climate patterns and estimate sea and ice levels. The data can show elements that affect our environment in ways that would not be possible with observations from the ground alone. …
Why is space so beautiful?
I am also inclined to think that outer space appears beautiful because it humbles the ego of humans. It’s just natural to find it beautiful, with the dark, dark expanse of outer space, dotted with simply trillions and trillions of stars. Then you see a huge army of stars in a particular formation, we call it a galaxy.
How high is the space?
Can an airplane fly without fuel?
The world’s first zero-fuel plane is finally close to flying around the world. For the first time in history, a solar-powered plane is flying around the world — all without a drip of fossil fuel. The plane has the wingspan of a Boeing 747, weighs as much as an SUV, and travels just 43 mph.
How do astronauts help us?
Astronauts work in mission control (the ‘voice’ that communicates with astronauts in orbit), check out procedures and the checklists the crew in space will use, help verify the space station and vehicle software, develop procedures and tools to be used during spacewalks or robotic operations, help scientists in …
What are 3 uses of satellites?
What Are Satellites Used For?
- Television. Satellites send television signals directly to homes, but they also are the backbone of cable and network TV.
- Business & finance.
- Climate & environmental monitoring.
- Land stewardship.
Can a plane fly to space?
The bottom line is that airplanes can’t fly in space because there is no air in space. Airplanes rely on air to produce both lift and propulsion. Since there isn’t any air in space, airplanes must stay within the Earth’s atmosphere.
What is the most beautiful thing in space?
A: “The most beautiful thing in the universe is the human ability to comprehend it. “Our universe is extraordinarily complex, with processes occurring on all scales, from the subatomic world to the universe at large.
What are the dangers of traveling to space?
5 Hazards of Human Spaceflight
- Isolation and confinement.
- Distance from Earth.
- Gravity (or lack thereof)
- Hostile/closed environments.
- Human research essential to space exploration.
How big is a space satellite?
Size varies. Communication satellites can be as big as a small school bus and weigh up to 6 tons, the Federal Communications Commission says. Most weigh a few tons or less. Some that are used briefly are 4 inch cubes and weigh about 2 pounds.
Why do we need satellites?
Why Are Satellites Important? The bird’s-eye view that satellites have allows them to see large areas of Earth at one time. This ability means satellites can collect more data, more quickly, than instruments on the ground. Satellites also can see into space better than telescopes at Earth’s surface.
Why do we fly in space?
Astronauts float around in space because there is no gravity in space. Everyone knows that the farther you get from Earth, the less the gravitational force is. Well, astronauts are so far from the Earth that gravity is so small. Because there is no air in space.
What are the benefits of going to space?
The benefits of space can be categorized as either direct or indirect. The direct benefits of exploration include the generation of scientific knowledge, the diffusion of innovation and creation of markets, the inspiration of people around the world, and agreements forged between the countries engaged in exploration.
Why do I love space so much?
Some people like space because of its beauty, of supernovas, stars, moons, planets, and galaxies. Some people are interested in the answers that space stores for us, untouched environments that we could experiment with.
