Experience Earth in Real-Time! Tune into Mashable’s Live Stream from Space.

Sure! Here’s a revised version of the content with the specified changes:

Behold, Earth. The live stream you see above is beamed down from the International Space Station, which orbits some 250 miles above our planet. It's filmed by the Earth and space live streaming company Sen, whose high-definition camera system, SpaceTV-1, peers down at sprawling forests, oceans, metropolises, and beyond. "You see a beautiful planet and a borderless world," said Sen's founder and CEO, Charles Black. Anyone with internet access can watch it. "It's about democratizing space," Black added.

The video from Sen averages about 20 hours of live footage every day, with just a few seconds of latency as the signal travels to Earth's surface via NASA's Tracking and Data Relay Satellite System. This signal is then distributed to viewers around the globe. Spread out over 24 hours, there are routine loss of signal periods, which can last from fewer than two minutes to about 20 minutes, during which Sen will replay recently live streamed footage. Signal losses in orbit occur for various reasons, such as when NASA switches satellite relays during downlinking or when the signal is blocked by the station's sprawling solar arrays. 
"You never know what you might see." - Charles Black

Tuning in, you'll regularly encounter new sights. The space station orbits Earth about 16 times a day, and during each orbit, the floating laboratory shifts slightly to the west. "Whenever you log on, you can see something different," Black said. "You never know what you might see." When the station is orbiting above the nightside of Earth, a message on the bottom of the screen will read "Sunrise in X minutes." The messaging also indicates the location of the view, such as "Tanzania."

We've certainly come a long way since U.S. researchers captured the first view of Earth from space in 1946. It was grainy but poignant. Some 14 years later, a new era in Earth observation began when the U.S. weather satellite TIROS-1 beamed back over 19,000 orbital images in 1960. Now, you can watch high-definition live footage directly from your device.
