There's an
unearthly market blooming in the Brazilian jungle.
Aerospace giants Boeing and Lockheed Martin, along with
small-rocket builder Vector, have expressed interest
in launching from an old rocket complex on Brazil's Atlantic coast.
The Alcantara base sits about 140 miles south of the Earth's
equator, making it a prime location for launching satellites, a
$260 billion business. From this spot, certain satellites can be launched
more efficiently than from spaceports in the U.S.
The dormant military base "makes total sense" to
be used "for launching large satellites with big rockets into
geosynchronous orbits," or GEO, Jonathan McDowell, an astrophysicist at
the Harvard-Smithsonian Center, told CNBC.
These GEO satellites, which circle the globe tens of
thousands of miles away, orbit at the equator to provide maximum coverage for
services such as communications or broadband.
Launching from the equator itself, therefore, is
advantageous because it requires less fuel. A launch from a latitude much
farther north — such as NASA's Kennedy Space Center in Florida or Vandenberg
Air Force Base in California — requires rockets sending satellites to GEO to
change direction in flight to reach the equator.
Sometimes called
"bootlegging," that process requires firing a rocket's engines
multiple times to angle into position.
Launching those same satellites from Alcantara would save as
much as 20 percent more fuel compared with a location such as Florida, McDowell estimated.
Similar savings would be seen for launches to equatorial
low-Earth orbit, or LEO, McDowell noted. The case for Boeing and Lockheed
Martin "makes sense," McDowell said, due to the large size of
GEO-bound satellites.
Tapping a new market
Vector, on the other hand, wants to use its small rockets to
tap a new equatorial LEO market by launching dozens of small satellites. The
company's Vector-R rocket, which is nearing its first orbital launch in July,
is about one-sixth the size of the often-watched SpaceX
Falcon 9 rocket. At less than $3 million per launch, Vector
wants to use its rocket to tap into the rapidly-growing microsatellite
industry.
Traditionally, equatorial LEO has been a minuscule portion
of the satellite market. Small satellites are usually destined for orbits
running over the Earth's poles. Reaching those polar orbits means "an
equatorial launch site isn't an advantage," McDowell said.
Vector CEO Jim Cantrell thinks the demand for equatorial LEO
is already here. Last month, Cantrell expressed even more enthusiasm than
Boeing and Lockheed Martin when he told CNBC his company "is very
interested in the opportunity" due to the fuel efficiency advantage.
"From a satellite launch perspective, there are many
who want to launch into equatorial LEO," Cantrell said, in a follow-up
interview. "We have seven customers at present that are looking for this.
And [launching aboard a small rocket] is one of those services no one seems
able to provide, as these customers are definitely not able to find a
rideshare opportunity."
These are "American and European customers" for
Vector, Cantrell said, and include both start-ups and established customers. Of
those looking to launch with Vector, communications satellites "are
probably 75 percent of the demand," while remote sensing and imaging
satellites are the remaining 25 percent, Cantrell said. The Vector-R rocket can
lift about 80 kilograms into equatorial LEO, the rocketeer noted.
The Guiana Space Centre is another launch complex in the
region, located to the north in French Guiana, a French territory. The complex
is positioned around 345 miles north of the equator, providing similar launch
advantages as Alcantara.
Operational for nearly half a century, the Guiana
Space Centre is owned by the European Space Agency and operated by the French
national space agency.
"[The launch complex in] French Guiana has been a
reason why [European rocket company] Arianespace has gotten so much of the
commercial GEO market since it started in the 1980s," McDowell said.
The future for Alcantara
Reopening Alcantara would allow U.S. companies to equal the
playing field against European competitors. But the Brazilian site isn't ready
for rocket launches just yet.
Alcantara has been little used since August 2003,
when a rocket with two satellites onboard exploded on the launchpad, killing 21
people and damaging the launchpad's infrastructure.

Brazil's
defense minister, RAUL JUNGMANN, has
said the complex may be able to support up to five launchpads, but McDowell
expects it will be "at least 5 years" until the first U.S. orbital
launch from Alcantara occurs.
Vector's minimal infrastructure required — its rocket needs
little more than a flat concrete foundation — means it may be able to get up
and running a little more quickly.
"It would take us years to get service in place, so the
soonest I could see us launching from Alcantara is 2020," Cantrell added.
Early talks have been reported to be positive but the
remaining hurdle to a deal with Brazil is the signing of a Technology
Safeguards Agreement with the U.S. to protect sensitive information about any
rockets exported to Brazil.
A political window of opportunity may be at hand, as
Brazilian lawmakers and military officials alike have expressed eagerness to
establish a new TSA, matched in turn by the interest of U.S. companies.
A
non-proliferation agreement with the U.S. may see Brazil become the next
step in
an increasingly valuable space industry.
