Norway's
Space Adventures
By RedOrbit
Space exploration
is more than daring astronauts and thrilling
astronomy. It has practical applications that
are becoming increasingly apparent. Norway is
a small but important space nation that envisions
playing a larger role in this exploration than
do most countries. NORWAY HAS A LONG TRADITION
AS A SPACE NATION, IN no small measure due to
its northern position on the globe. Kristian
Birkeland's famous Terrella experiment in 1896
in which he created synthetic northern lights
can be seen as the start of modern space activities.
He understood that it was the sun that caused
the aurora borealis (as well as its southern-hemisphere
counterpart, the aurora australis) and that
particles from the sun interact with earth's
magnetic field and atmosphere. Thus the aurora
and solar research led to the establishment
of the rocket range on the north Norwegian island
of Andoya, where the first Norwegian research
rocket was launched in 1962. Researchers from
a number of countries now utilize this rocket
range in their studies of the northern lights
and the earth's atmosphere and the facility
is NASA's most important launch facility for
sounding rockets outside the U.S.
A research environment blossomed
early in Norway and today Norway has one of
the strongest solar research groups in the world.
The solar observatory at Harestua, north of
Oslo, was opened in 1957, but today observations
of the sun are carried out from large international
observatories as well as from satellites. Norwegian
scientists participated in the solar telescope
HRTS (High Resolution Telescope and Spectrograph)
that flew on the space shuttle Challenger in
1985. More recently they played a central role
in the successful SOHO mission-a large satellite-based
solar observatory including 12 different telescopes
and instruments launched in 1995. This was a
collaboration between the European Space Agency
and NASA in which Norwegian industry provided
equipment and services to the tune of 80 million
Norwegian kroner. For six years, a Norwegian
[the author] served as deputy project leader
of this mission. Also, Norway is currently involved
in the Japanese solar satellite Hinode by the
downlink of data at the Svalbard archipelago
and at a European data center at the University
of Oslo.
One of the most daring space projects
in history was the successful landing of the
Huygens space probe on Saturn's mysterious moon
Titan and transmission of the first pictures
from Titan's surface. Huygens was mounted on
the mother sonde Cassini, which is still circling
Saturn. Norway's Kongsberg Defense & Aerospace
(KDA) delivered the test equipment used during
development and integration of Huygens. Moreover,
the Norwegian Defense Research Establishment
(NDRE) was responsible for one of the instruments
aboard Cassini-as well as for instrumentation
for ESA's future Mars project, ExoMars.
NASA's satellite SWIFT has been
built in order to study gamma burst-the most
violent explosions in the universe. The x-ray
camera aboard SWIFT was developed in cooperation
with Gamma Medica-IDEAS outside Oslo. Technology
from this camera is also being used in breast
cancer scanning and can discern smaller tumors
than normal mammographie methods. The same principle
is being applied in airport security controls.
Gamma Medica-IDEAS and the University of Bergen
are working on an even newer x-ray camera, ASIM
(Atmosphere-Space Interaction Camera), to be
placed beneath the International Space Station
(ISS) to study the mysterious lightning phenomena
in the earth's atmosphere called "Sprites"
and "Elves." This camera will also
permit physicians to make even better mammograms,
and thereby enable them to detect tumors at
an early stage. A nice example of how development
of sensitive space electronics will give spin-offs
for our society down on Earth.
The research and technology group
SINTEF in Trondheim has developed the Multi-Component
Trace Gas Monitor (ANITA) to monitor air quality
on the International Space Station. The instrument
was launched last summer on the space shuttle
to detect whether the air might contain gases
potentially injurious to the astronauts.
The international space station
also contains a mini-greenhouse with a number
of plant-cultivation chambers developed by Prototech
in Bergen in collaboration with the Plant Biocenter
at the Norwegian University of Technology and
Sciences (NTNU) in Trondheim. They cost 500,000
kroner apiece and can safely be said to be Norway's
most expensive flowerpots. All experiments in
this mini-greenhouse (European Modular Cultivation
System) are controlled and operated from the
Norwegian User Support and Operation Center
at the Plant Biocenter. Everything-water, nutrients,
light, temperature-is controlled by commands
from this center. If humans are going to be
able to travel into space, they must be able
to produce their own food. Therefore it is necessary
to learn how plants thrive in the absence of
gravity.
Svalbard is one of the places on
earth where the environment most resembles conditions
on Mars. The area around Bockfjorden is unusually
volcanic, with warm springs, ice and permafrost.
The geology resembles conditions as they could
have been on Mars in its childhood four billion
years ago. The Norwegian project AMASE (Arctic
Mars Analog Svalbard Expedition) offers NASA
and ESA unique possibilities for testing their
future Mars rovers and instruments before they
are sent to Mars. Even space apparel has been
tested in Svalbard.
Norwegian space activities had
a turnover of close to six billion kroner in
2007. This makes space a bigger industry than
forestry in Norway. Many people equate space
industry with the manufacture of parts for satellites
and rockets, but the largest part of the space
sector, generating two thirds of the sector's
annual turnover, is telecommunication (transmission
of television, telephone, pictures, and data
via satellite).
Norway was one of the first countries
to utilize satellite communication. The motivation
was the need for communication with our vast
merchant marine, offshore operations, and settlements
on Svalbard. Also, one of the first space-based
services in Norway was use of satellites to
localize distress signals from shipwrecks. Telenor
is one of the leading providers of satellite
communications. Norwegian industry also helped
lead the way with satellite phones and, in 2006,
developed the world's first broadband satellite
phone. These are frequently used by international
journalists reporting back from remote places
without cell phone coverage such as disaster
areas and war zones.
Norspace in the town of Horten
has found an industrial niche by building filters
that distinguish signals from noise in satellites
and Prototech is building the gilded boxes that
contain the electronics. So most communication
satellites launched today contain 100 kilograms
of Norwegian electronics and even China purchases
advanced electronics for their satellites in
Norway.
When the ESA launches its 59-meter-tall
Ariane 5 rockets near the equator in French
Guiana the two large side-mounted solid rocket
boosters are held in place by lock-and-release
mechanisms from Kongsberg Defense and Aerospace
(KDA) and with accessories from Prototech. The
large bolts cost 100 million kroner to develop
and can't be made in an ordinary metal shop.
Two minutes after firing the rockets have exhausted
their fuel. Small explosive charges in the bolts
crack them with surgical precision in the course
of five- thousandths of a second. The rockets
are thereby pushed away from the main rocket
by little rocket jets developed by NAMMO in
Kongsberg.
Several of ESA's research satellites
have components from Norwegian industry, and
Norwegian mechanisms for steering solar- cell
panels or antennas are now in orbit around Venus
and Mars. A Norwegian detector is flying on
the ESA/NASA built Cassini-Huygens mission that
is orbiting Saturn.
TODAY THE UTILIZATION OF SPACE
IS INTERWOVEN IN OUR society. Satellite services
are used every day by almost every one of us,
either directly or indirectly. Without the services
provided by space exploitation our communication-hungry
and technology-based society would not be able
to function. This is true of television, data-
and telecommunication, rescue operations and
navigation to weather forecasting and environmental
surveillance.
In spite of a relatively sparse
population of only 4.7 million, Norway is Europe's
second-largest country in area-that is, if you
include its economic ocean areas and far-flung
islands. Within this area are huge amounts of
valuable resources such as oil, gas and fish.
This large an area and relatively few people
present us with geographic and climatic challenges
that can only be satisfactorily solved with
extensive use of satellites. These can monitor
climate, ice conditions, vessel traffic and
oil spills. Satellites also distribute TV broadcasts,
phone conversations and data transfer.
Furthermore, satellites provide
ships, automobiles and people with positions
so that we can navigate safely. Just a few years
ago it was a sensation when taxis installed
GPS equipment. Today, this technology is standard
in most cars. Cell phones with GPS receivers
are already on the market. On Svalbard, Norway
has the world's biggest station for weather
satellites in polar orbits. The satellite station
is operated by Kongsberg Satellite Services,
and it also has antennae in Tromso, Grimstad
and at Troll Station in Antarctica. This makes
them the world leader in retrieval of satellite
data from polar-orbiting satellites. Their biggest
customer is NASA and NOAA and a large part of
the data for the U.S. weather services are coming
down via Svalbard. So next time you see the
weather presenter on TV showing some spectacular
imagery of a hurricane from space there is a
large chance this image travelled from space
via Svalbard and Norway before being transmitted
to the U.S.
NORWAY LED THE WAY IN UTILIZING
RADAR SATELLITES TO detect oil spills from ships
and oil installations. Radar satellites can
"see" at night and through cloud cover,
making it possible to immediately see clandestine
and illegal release of oil so that the coast
guard can be alerted. Radar satellites can also
be used to monitor ship traffic far off at sea.
In a few years Norway will start operating its
own satellite for keeping track of all ship
traffic in its economic ocean areas. At present
coastal radio stations can only detect identification
signals from ships closer than about 40 nautical
miles off shore.
Satellites also monitor natural
phenomena such as volcanic eruptions, earthquakes,
ocean currents and extreme wave action. Pictures
from space can be extremely important when rescue
operations have to be initiated after a powerful
earthquake, especially if the catastrophe occurs
in a remote location. Space pictures can also
help to map algal blooms at sea-information
useful to fishing fleets and fishing farmers.
We are all used to receiving detailed and rapidly
updated weather reports via the Internet and
cell phones, something that would be impossible
without satellites.
Climate changes and the environment
are currently of top international concern.
Satellites will become increasingly important
for the surveillance of the Earth's environment
since they will be able to furnish uniform information
of large areas. Satellites measure changes in
polar ice extent and the amount of ozone and
other gases in the Earth's atmosphere. They
measure changes in sea level, the amount of
water vapor in the atmosphere, cloud accumulation
and changes in vegetation. Last but not least,
it is important to keep an eye on changes in
solar activity where the amount of radiation
of light and particles toward Earth vary over
time. Historically, the sun has caused many
climate changes on Earth and much points to
it also having contributed to climate changes
during the last 150 years. If we want to know
how much humans contribute to climate change
it is critical to first determine the natural
forces from the sun.
Because Norway is located so far
north it has the possibility to utilize space
better than most other countries. Polar orbiting
satellites are the ones collecting the most
detailed information about the Earth. This means
that the Norwegian territory will be observed
much more frequently than most other countries.
The geographic advantages of Norway's northern
latitude for space activities is important,
both to meet national needs and to provide services
for international clients.
An ambitious vision of the Norwegian
Space Center is that by 2015, Norway will be
the country that benefits most from space. This
means that services from space will become increasingly
important for all Norwegians, even if they are
not aware of it yet. Not before GPS fails, the
TV screen goes blank during the Super Bowl,
or your bank machine loses contact with the
satellite that synchronizes your code, or the
weather satellite no longer spots the storm
coming from the sea, will we notice how vital
a role space plays in our everyday lives.
One more thing. Most people associate
space exploration with the sciences. In the
future, however, it will concern lawyers, economists,
journalists, environmentalists and foreign-aid
workers to the same extent.
Large solid boosters on the 59-meter-tall
Ariane rocket are held in place by lock-and-release
mechanisms made in Norway.
Svalbard is one of the places on
earth where the environment most resembles conditions
on Mars . . . four billion years ago.
The solar observatory SOHO (Solar
and Heliospheric Observatory) was launched in
1995 to study the atmosphere, surface and interior
of the sun, an effort supported with equipment
and services by Norway to the tune of 80 million
Norwegian kroner.
Norway is currently involved in
the Japanese solar satellite Hinode by downlinking
data 15 times every 24 hours at the Svalbard
archipelago and at a European data center at
the University of Oslo.
European Space Agency (ESA)
The European Space Agency is Europe's
gateway to space. Its objective is to shape
the development of Europe's space competence
and to ensure that investment in space will
continue to benefit the people of Europe.
By coordinating and pooling the
economic and intellectual resources of its 17
member countries, the ESA can undertake and
carry out programs and activities that far exceed
those of any individual nation.
ESA's 17 members are: Austria,
Belgium, Denmark, Finland, France, Germany,
Great Britain, Greece, Ireland, Italy, Luxembourg,
Netherlands, Norway, Portugal, Spain, Sweden
and Switzerland.
Norwegian industry helped lead
the way with satellite phones and developed
the world's first broadband satellite phone.
The Norwegian User Support and
Operation Center, located in Trondheim, is used
to operate and monitor plant-cultivation chambers
in the International Space Station.
Satellites also measure natural
phenomena such as volcanic eruptions, earthquakes,
ocean currents and extreme wave action.

with synthetic northern lights can be seen as
the start of modern space activities.
