Virgin Galactic sells 100 more space tickets after flying Richard Branson last summer
The current price of the fare is $450,000 per seat.

The current price of the fare is $450,000 per seat, well above the $200,000-$250,000 paid by some 600 customers from 2005 to 2014.
In total, the company has now sold 700 tickets, a spokesperson told AFP.
"We are entering our fleet enhancement period with a clear roadmap for increasing the durability, reliability and predictability of our vehicles in preparation for commercial service next year," said CEO Michael Colglazier in a statement.
"Demand for space travel is strong, and we've been selling seats ahead of the pace we had planned."
Established in 2004, Virgin Galactic is seeking to cash in on the success of a high profile test mission in July, which saw Branson beat by a matter of days Blue Origin owner Jeff Bezos in their billionaire space race.
But since then, the company, which flies out of Spaceport America in the New Mexico desert, has faced setbacks.

In October, Virgin said it was postponing by several months a mission with members of the Italian Air Force, after lab testing revealed certain materials used in its vehicles might have fallen below required strength margins, necessitating further analysis.
The company is currently in the process of enhancing its vehicles.
As a publicly traded company, Virgin Galactic is also required to be more transparent about its finances.
