While it doesn't emit, absorb, or reflect light, we know dark matter exists because of the way its gravity affects visible matter. Galaxies rotate faster than they should based on the mass we can see, and large-
If a satellite has a mass on earth of 50 kg, what is its mass on a planet where the gravitational constant is 1/10 its value on Earth and the planet is 1 million km from Earth? A 1.0kg mass weighs 9.8n on Earth's surface, and the radius of the Earth is roughly 6.4x10^6m. W...
In previous missions sending payloads into the Earth's orbit, a rocket is required to achieve a separation velocity equal to the first cosmic velocity, or approximately 7.9 kilometers per second. However, this mission requires a separation speed exceeding 11.2 kilometers per second, known as the...
The upshot of building a bigger rocket is pretty straightforward: heavier payloads and greater range. When it's done, Starship might be able to wrestle up to 250 tons intolow-Earth orbitin an expendable configuration or 150 tons with Super Heavy recovery. SpaceX is also working on orbital ...

your center of mass is pulling back at the Earth. But the more massive body barely feels the tug from you, while with your much smaller mass, you find yourself firmly rooted thanks to that same force. Yet Newton's laws assume that gravity is an innate force of an object that can act...

The discovery of a Permian-Triassic boundary section in northeastern Utah provided an opportunity to study the chemistry and geology associated with this event that led to one of the greatest mass extinctions on the planet. From 83% to 97% of the species living on the planet went extinct ...
