The other muscles that help you execute the decline bench press exercise are the clavicular head of your pectorals, anterior deltoids, triceps and biceps.
How fast does the Space Station travel? The International Space Station travels in orbit around Earth at a speed of roughly 17,150 miles per hour (that's about 5 miles per second!). This means that the Space Station orbits Earth (and sees a sunrise) once every 92 minutes! You can see the ISS' location and speed at this link which also has a real-time video feed from cameras attached to the outside of the station. Cool Cosmos is an IPAC website.
I will discuss both separately. The space shuttle does have a maximum speed of 17,500 mph, but that speed is relative to the Earth. If you think about the space shuttle's velocity relative to the Sun, then the answer is the sum of Earth's velocity plus that of the shuttle. This means that the shuttle is moving at 67,000 + 17,500 mph (84,500 mph). So the space shuttle actually does move faster than the Earth. However, the shuttle speed is actually irrelevant to your question, because the shuttle never truly leaves Earth's gravity.
