True or False. Satellites are repaired in space.<br> True<br> False
dalvyx [7]
True
Though initially designed for refueling, NASA plans to expand the capabilities of Restore-L to include other maintenance activities that will extend the life of an orbiting spacecraft. “Restore-L effectively breaks the paradigm of one-and-done spacecraft,” says Satellite Servicing Capabilities Office (SSCO) Associate Director Frank Cepollina in a prepared statement. Once deployed, the robot could act as a gas station in space, providing satellites with much-needed propellant. On the maintenance side, the robot one day may be able to manufacture and assemble components in space and use them to service a satellite. It also may be used to reduce space accidents by removing space junk from orbit.

How earthquake occur or what happen when it came​
miss Akunina [59]

Hello, welcome to Brainly!

Earthquakes are typically prompted when rock underground suddenly breaks alongside a fault. This sudden launch of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing in opposition to each other, they stick a little. They don't simply slide smoothly; the rocks seize on each other. The rocks are nevertheless pushing towards each other, however now not moving. After a while, the rocks spoil because of all the stress that is built up. When the rocks break, the earthquake occurs. During the earthquake and afterward, the plates or blocks of rock start moving, and they proceed to go till they get caught again. The spot underground the place the rock breaks is known as the focal point of the earthquake. The area proper above the center of attention (on pinnacle of the ground) is called the epicenter of the earthquake.
