How wide is the sun? How much does it weigh? How far is it from earth?Sun:The source of the light on earth is the sun. Sun is one of the stars made up of hydrogen and helium molecules. The nuclear fusion reaction between hydrogen and helium releases an enormous amount...
Since you only weigh 100 pounds in your spacesuit, you can see that the weight of your "fuel" dwarfs the weight of the payload (you). In fact, the fuel weights 36 times more than the payload. And that is very common. That is why you have to have a huge rocket to get a tiny ...
Propulsion would then be provided by the air-breathing rocket vehicle, which will inhale oxygen for about half of the flight to burn fuel. The advantage of this is it won't have to store as much oxygen on board the spacecraft as past spacecraft have, thus reducing launch costs. Once ...
and when a fully-loaded semi roars down the highway, you can feel the rumble from hundreds of yards away. With the exception of some custom, specially-made vehicles likeSpaceX’s rocket transport, semi-trucks are often the largest vehicles on the road. But while many of us have a good ...
That’s why SpaceX has a long term plan to build a rocket that will make Falcon 9 look like a hot dog— The Mars Colonial Transporter. The MCT rocket will be a giant, powered by a much more powerful SpaceX engine, called the Raptor, that’s currently in the works—and its spacecra...
How Much Moonshine Does This Recipe Yield? The yield of moonshine from a 5-gallon recipe using 8.5 lbs. of flaked corn maize, 1.5 lbs. of crushed malted barley, bread yeast, and optional sugar can vary significantly due to several factors. These include the efficiency of fermentation, which...
As mentioned in the introduction, 1 G is equal to the force of Earth's gravity and determines how much we weigh. One G of acceleration is equal to 32 feet/second2 (9.8 m/s2). This means that if you drop something off of a cliff, it will fall at a rate of 32 feet/second2. ...
This is why small rockets are prone to flipping, but a similar shape with a much larger rocket allows you to nearly ignore aerodynamics when taking off. Another consequence of this is that big rockets are much harder to turn than small ones. Small probes that only weigh a few tons can ...
Astronomers call this giant black holeSagittarius A*(Sgr A* for short), which is located about 26,000 light-years away from Earth in the center of our galaxy. Black holeshave two fundamental properties: their mass (how much they weigh) and their spin (how quickly they rotate). Determining...
At launch, they include a 550-pound (250-kg) solid rocket booster and weigh 3,200 pounds (1450 kg). The booster falls away once it has burned its fuel. The wings, tail fins and air inlet unfold, and the turbofan engine takes over. This engine weighs just 145 pounds (65 kg) and ...
