WASHINGTON, United States — The era of space tourism
is set to soar, with highly symbolic flights by rivals Virgin Galactic and Blue
Origin scheduled just days apart.

Virgin Galactic — founded by flamboyant British billionaire
Richard Branson — is planning for a July 11 space flight. Blue Origin — started
by Jeff Bezos of Amazon fame — is set to blast off on July 20.
The two companies will serve the nascent market for
suborbital flights lasting just a few minutes, long enough for passengers to
experience weightlessness and view the contour of the planet.
But that's where their similarity ends.
Branson, who heads the Virgin Group conglomerate that
includes everything from entertainment to financial services to telecoms,
founded Virgin Galactic in 2004. The 70-year-old's previous daredevil exploits
include crossing the Pacific in a hot-air balloon and navigating the English
Channel in an amphibious vehicle.
is 57 years old and the world's richest man. A
science fiction fan, he founded Blue Origin in 2000 and recently stepped down
as Amazon CEO to focus on space projects and other endeavors.
Different spacecraft

The spacecraft developed by the two companies could not be
more different.
Virgin Galactic's spacecraft is not a classic rocket. It's
attached to the belly of a large carrier airplane that takes off from a runway.
After an hour it reaches an altitude high enough to release
the smaller
spacecraft, the VSS Unity, that in turn fires its engines and
reaches suborbital space — where passengers float weightlessly for a few
minutes — then glides back to earth.
The spacecraft can accommodate two pilots and up to six
passengers. The cabin has 12 large windows and 16 cameras.
Blue Origin in contrast is more of a classic rocket
experience, with a vertical blast-off that accelerates to more than Mach 3, or
three times the force of Earth's gravity.
Once it reaches the proper altitude, a capsule separates
from the booster and then spends four minutes at an altitude exceeding 100
kilometers, during which time those on board experience weightlessness and can
observe the curvature of Earth.
The booster lands autonomously on a pad two miles from the
launch site, and the capsule floats back to the surface with three large
parachutes that slow it down to about a mile per hour when it lands.
The capsule has six seats and six large windows.
Commercial ambitions

Virgin Galactic plans to start regular commercial operations
in early 2022, and is aiming to carry out 400 flights per year from Spaceport
America, its base in New Mexico.
Some 600 tickets have already been sold, including to
Hollywood celebrities, for prices ranging between $200,000 and $250,000.
Tickets are expected to be even more expensive when they go on sale to the
public.
Blue Origin has yet to announce ticket prices or a date for
the start of commercial operations. But a seat for the July 20 flight was sold
an auction — and the mysterious winner paid $28 million.
