Now, the firm is ready to put one of these "flight proven" vehicles on the launch pad again.
Re-using stages is part of SpaceX's strategy to lower the cost of access to space.

Stopwatch with High Measuring Ability

Scientists at NASA have developed a stopwatch timer that can measure within a fraction of a billionth of a second. This is an advance that can help record precise height measurements of sea ice, glaciers, forests and the rest of the Earth's surfaces.
Engineers at NASA's Goddard Space Flight Centre built the timer for the Ice, Cloud and land Elevation Satellite-2 (ICESat-2) scheduled to launch in 2018, which will use six green laser beams to measure height.
