In a far-reaching reorientation of its programs, the US National
Aeronautic and Space Administration (NASA) budget has effectively
capped science spending for the five-year period from 2007 to
2011. Programs designed to investigate more fundamental scientific
questions about the character of the solar system and the universe
are being sacrificed to enable NASA to carry out President George
Bushs grandiose scheme to establish a permanent settlement
on the moon in preparation for a manned mission to Mars.
NASAs announcement in February was part of Bushs
budget cuts to federal science spending by 1 percent to $59.8
billion. The changes to NASAs program are mirrored in the
overall science budget, which is focussed more narrowly on projects
with commercial payoffs or to strengthen the US military. Bushs
American Competitive Initiative, which is aimed at
bolstering US corporate interests at the expense of their rivals,
will consume $5.9 billion. Presidential science adviser John Marburger
bluntly declared: The point is, were prioritising.
Several NASA programs have been delayed, including:
* The Global Precipitation Measurement (GPM) mission would
have launched a satellite to accurately measure all forms of precipitation
on Earth. The study was aimed at developing a more accurate scientific
understanding of earths weather system and its response
to natural and human-induced changes. The satellite was due for
launch in 2010 and will now be delayed by 30 months.
* The Space Interferometry Mission PlanetQuest (SIM) planned
for launch in 2015, which has now been delayed by three years.
SIM is designed to more accurately map the positions and distances
of stars throughout the galaxy and to probe nearby stars for Earth-sized
planets with the possibility of life. The aim is to make a more
accurate estimation of the size and age of the universe.
* Other projects such as the Orbiting Carbon Observatory, the
Landsat Data Continuity Mission, the Space Interferometry Mission
and the Wide-Field Infrared Explorer (WISE) have been delayed
for one to three years but their future is uncertain.
Many other NASA projects have been deferred indefinitely or
scrapped altogether, including:
* The Terrestrial Planet Finder (TPF) mission was to launch
two space telescopes designed to explore the formation of planets
in stellar dust clouds.
* A mission to Europa, one of Jupiters moons thought
to possibly contain liquid water and life, has also been axed.
The cancellation of the project is a huge blow to the science
of astrobiologythe search for extra terrestrial life. NASAs
budget for projects in this field has been slashed by 50 percent.
Reta Beebe, an astronomer at New Mexico State University, commented:
The proposed budget transforms an existing, vibrant program
into a stagnant holding pattern ... the damage is immediate and
increasingly irreversible.
Four locations in the solar system are believed to have the
potential to harbour primitive life forms: Mars, Jupiters
moon Europa, Saturns moon Titan and Saturns moon Enceladus,
where scientists have just discovered a plume of water. Most of
these discoveries have resulted from previous NASA probes. Any
follow up will be impossible under the current funding regime.
* The Laser Interferometry Space Antenna (LISA) was to search
for gravity waves as predicted by Einsteins theory of General
Relativity. Gravity waves could potentially be used to map the
warped space-time around black holes and to further our understanding
of the nature of space, time and gravity.
* The Constellation-X Observatory was to have been a array
of orbiting X-ray satellites linked together to act as one giant
X-ray telescope. The observatory was to investigate black holes,
galaxy formation and the evolution of the universe scales as well
as more perplexing phenomena such as dark matter and dark energy.
* The Mars Sample Return was intended to pick up rock samples
from Mars and return them to Earth for analysis.
* The NuSTAR project was a high-energy X-ray telescope intended
to survey the sky in a section of the electromagnetic spectrum
never before explored. It had the potential to find previously
unobserved objects.
* The Stratospheric Observatory for Infrared Astronomy (SOFIA)
was a joint project with the German Aerospace Centre (DRL). The
plan was to fly a 2.5 metre reflecting telescope to observe infrared
radiation at a height of 12 kilometres, above any interfering
atmospheric moisture. SOFIA was aimed at determining the composition
of planetary atmospheres and surfaces; investigating the structure,
evolution and composition of comets; determining the physics and
chemistry of the interstellar medium; and exploring the formation
of stars and other stellar objects.
* The Hydrosphere State (Hydros) mission has been cancelled.
It was designed to provide the first global view of the Earths
changing soil moisture and the cycle of land surface freeze and
thaw in cold climates. The aim was to understand more precisely
the Earths carbon, water and energy cycles.
* The Joint Dark Energy Mission (JDEM) was to place an observatory
in space designed to detect dark matter. Some scientists believe
that 70 percent of the universe is made up of dark matter and
that its presence could explain why the universe is expanding
at an accelerating rate.
One of the most insidious cutbacks is to funding
of data analysis by students who work through the mountains of
data accumulated by every space mission. Professor of planetary
astronomy at the California Institute of Technology Michael Brown
explained: The fact that theyre cutting the research
budget means that Im not going to be able to fund students...
Were out there flying around Saturn, collected data at some
incredible rate and most of it goes and sits in an archive.
Some projects have been decades in the making and involve extensive
international collaboration. NuSTAR was being carried out in collaboration
with the Danish National Space Centre and the Constellation-X
Observatory was planned with the Brera Astronomical observatory
in Italy.
Funds are being diverted to bolster the Moon exploration program,
which will grow by 30 percent to $3.98 billion in 2007. There
is also an additional $2.6 billion for the International Space
Station (ISS). The plan is for a new generation of space vehicles
to ferry scientists and astronauts back and forth from the International
Space Station and replace the present aging and disaster-prone
space shuttles.
Bush aims to establish a permanent manned lunar presence by
the year 2020 to prepare for the future exploration and colonisation
of Mars. In his announcement in January 2004, he cited the spirit
of discovery and compared the US exploration of space with
earlier American explorers. Bushs intention was to evoke
John F. Kennedys vision for the Apollo missions in the 1960s
to given the impression his administration was embarking on a
grand scientific quest in outer space.
In fact, the proposed missions are closely linked to military
objectives and will be run in close conjunction with the Pentagon.
In March 2005 Bush appointed Michael Griffin as NASAs administrator.
Griffin joined the Reagan administrations Strategic Defense
Initiative Organisation or Star Wars program in 1986
as the deputy for technology and led the efforts to develop a
missile defence shield. Defence Secretary Donald Rumsfeld is known
for his advocacy of American superiority in space warfare.
The NASA cuts produced a furore among scientists in the US
and internationally. Executive Director of the Planetary Society,
Louis Friedman commented in February: Space science was
not just cut; it was eviscerated. Planetary exploration was savagely
pruned. The budget would delay or cancel several long-awaited
missions and proposed major decreases in scientific research.
The society has launched a Take Action Alert to mobilise
scientists against the measures.
An editorial in Nature entitled NASA in reverse
stated: NASA is undergoing a historic shift in direction
without consulting scientists or paying attention to their advice.
Projects with great appeal to scientists and to the publicincluding
the search for planets around other stars and the study of dark
energyare being abandoned so that NASA can return astronauts
to the moon half a century after the Apollo landings.
Associate Administrator for Science Mary Cleave justified the
cutbacks in a statement on March 13, saying: We all plan
and conduct our scientific explorations in a constrained Federal
budget environment made more so by recent events on the national
and international stage largely beyond the realm of science.
Her guarded reference to US occupations in Iraq and Afghanistan
underscores the priorities of the Bush administration, which will
have spent $500 billion on these criminal enterprises by the end
of 2006.
At a briefing for space scientists at NASA headquarters on
March 14, Cleave declared: Were going to have to do
some surgery, so to speak. Curator at the Museum of Natural
History in Washington, D.C. Glenn MacPherson, responded: There
has been no consultation with the science community. The science
cuts hurt everyone in this room. The Space.com website
commented on the meeting that the fury... was not kept within
US borders. Scientists from Europe also cautioned that the NASA
budget is damaging international cooperation.
The elimination of programs that have taken decades to establish
is a massive setback to scientific research, particularly into
fundamental questions of physics and cosmology. The disbanding
of teams of scientists, engineers and technicians will result
in the loss of accumulated experience and expertise as well as
significantly narrow the opportunities from training a new generation.
