What happens if a spacecraft encounters problems in the vacuum of space? While space travel can be very dangerous, there are plenty of fail-safes. NASA, in fact, is carrying out tests to make sure the Orion spacecraft is ready to safely carry crew on an alternate mission profile in the unlikely event that problems occur.
Recent and upcoming deployments of satellite laser communication systems are bringing Internet-like speeds for data transmission in space. The result could be a revolution in communication, both on Earth and across the solar system. Laser communications through optical fibers move tens of terabits of data every second between cities and across oceans. But for the
