Prolonged stays in space environments expose human subjects to multiple stressors with different effects and consequences for human physiology and psychological conditions. Some of those effects are well known and
countermeasures developed, other ones are still uncertain and study can’t be considered as sufficient.
Inspiration Mars private initiative currently is proposing to send a two-person crew on a round trip
flyby mission to Mars in 2018. Adding a human component to a Mars flyby exploratory by nature mission
offers unique opportunities for exposure astronauts to the deep space environments. At the same time
physiological limitations for human subjects and life support technology as well as human factors
science aspects of such a mission are not clear yet. This presentation will focus on preliminary
evaluation of the deep space manned missions Human Factors (HF) science aspects and assessment
of potential scientific outcome from this ‘bold endeavor’ - class exploratory missions.

The Politics and Promise of Near-Earth Asteroids
Dr. Mark V. Sykes Ph.D., J.D., CEO and Director, Planetary Science Institute
▼ More Info
Mark V. Sykes is CEO and Director of the Planetary Science Institute,
a non-profit corporation dedicated to the exploration of the solar system
for more than 40 years. Mark began his science career as an undergraduate at
the University of Oregon, studying photometric and polarimetric lightcurves of
eclipsing stellar binaries - particularly the first black-hole system, Cygnus X-1.
As a graduate student at the University of Oregon, he discovered cometary dust trails
using data from the Infrared Astronomical Satellite and engaged in ground-based studies
of asteroids in the thermal infrared. He is a Co-Investigator on the NASA Daw mission to
Vesta and Ceres in the asteroid belt. Sykes chairs the NASA Small Bodies Assessment Group,
which provides science input for the planning and prioritization of the exploration of asteroids
and comets. He is also a member of the Board of Advisors of Planetary Resources, Inc., a for-profit
corporation planning to mine asteroids. He is also involved with PSI's Atsa Suborbital Observatory,
and plans to travel into space to make telescopic observations using the XCOR Lynx as a platform.
Near-Earth objects are viewed primarily as hazards. One is noted for killing the dinosaurs.
This February, another much smaller object exploded over the Siberian city of Chelyabinsk in Russia,
injuring more than 1500 people. The perceived threat drove Congress in 1998 to direct NASA to find 90%
of asteroids having diameters exceeding 1 km. Recognizing the potential damage from another Siberian airburst
over Tunguska in 1908, Congress modified their mandate in 2005 to include
objects down to 140 meters in diameter.
However, asteroids represent more than just threats,
they represent the potential to expand human presence and economy
beyond Earth. The Obama administration has committed to sending a
crewed mission to a near-Earth asteroid by 2025 and
it is planning to propose that Congress allocate $100M in 2014
to begin planning for a mission to return a 5 meter object
to Earth orbit. A non-profit company says it will raise hundreds
of millions in donations to survey NEOs to reduce the hazard
threat. Private companies have started up with the goal of mining
asteroids and turning a profit. Is this the Dawn of a new space age? Or business as usual?

and the mining and minerals industries to discuss issues related to lunar, asteroidal, and planetary resources.
Just as our ancestors for centuries relied on the use of local resources to explore every
corner of our planet, so the utilization of space resources will enable the affordable establishment
of extraterrestrial exploration and operations by minimizing the materials carried from Earth.
The search and use of resources to produce materials, propellants, energy, and basic consumables
for life support on the Moon, asteroids, and other planets may very well become one of the main
drivers for continuing our exploration of space.

Department at Rensselaer Polytechnic Institute in Troy, New York. His prior
affiliations include the Planetary Geoscience Group and Institute for Astronomy
at the University of Hawaii (seven years), the MIT Planetary Astronomy Laboratory
(PhD Student and post-doc), and the Geology / Astronomy Departments at the University of Iowa
(BA & MS). Dr. Gaffey is a Chester Fritz Distinguished Professor at UND, a Leonard
Medal winner from the Meteoritical Society, a recipient of the G. K. Gilbert Prize
from the Geologic Society of America, and recipient of the Thomas J. Clifford Faculty
Achievement Award for Excellence in Research. Asteroid 3545 was named Gaffey in recognition
of his contribution to the field.
The DAWN mission to asteroids (4) Vesta and (1) Ceres was the ninth mission
in NASA’s low cost Discovery Program. The spacecraft was launched in September 2007
and went into orbit around the large main belt asteroid (4) Vesta in July 2011,
staying in orbit until September 2012, before departing for a rendezvous with asteroid
(1) Ceres in mid-2015. During the more than a year in orbit, the DAWN spacecraft imaged
the surface at high resolution and in many colors to map surface units. Additionally
visible and near-infra spectra were obtained of nearly the entire surface to assess
surface mineralogy, and gamma ray spectra were obtained to map elemental composition
of the surface. Although Vesta had been the most intensely investigated asteroid prior
to the DAWN mission, many surprises awaited the science team once data began to be returned.
One major goal of the mission was to test this asteroid as the parent body of the most common
type of igneous meteorites, the HEDs. Confirming such a link would allow the detailed chemical
and chronological data from the HED to be used to outline the geologic history of this largest
igneous body in the asteroid belt.

Recent military operations in Afghanistan, Iraq, and Kosovo indicate
space capabilities have become a foundational enabler of most U.S. military actions and
an increasingly important component of U.S. national security. Worldwide, there is growing
recognition and focus on the broad and ubiquitous contributions space capabilities make to
global prosperity and security. The 2001 Space Commission Report found that because U.S. military
and economic security has become so dependent on space capabilities, the nation could face a
“space Pearl Harbor.” The U.S. National Space Policy released in October 2006 stated: “In this
new century, those who effectively utilize space will enjoy added prosperity and security and will hold
a substantial advantage over those who do not. Freedom of action in space is as important to the United
States as air power and sea power.” And the National Space Policy of the United States of America
released in June 2010 indicates: “Space systems allow people and governments around the world to
see with clarity, communicate with certainty, navigate with accuracy, and operate with assurance.

Dr. Wendell Mendell is a Planetary Scientist serving as Assistant Administrator
for Exploration in the Directorate for Astromaterials Research & Exploration Science of
the NASA Johnson Space Center, where he has been employed since 1963. He is married and has
four children. Dr. Mendell has a B.S. in physics from CalTech; a M.S. in physics from UCLA;
and a M.S. in Space Science and a Ph.D. in Space Physics and Astronomy from Rice University.
His scientific research focus is remote sensing of planetary surfaces, particularly specializing
in thermal emission radiometry and spectroscopy of the Moon. Since 1982, his activities in NASA
have focused on planning and advocacy of human exploration of the solar system, especially on the
establishment of a permanent human base on the Moon. His interests lay as much with policy issues
as with technical solutions. He is most well known as the editor of the volume, Lunar Bases and Space
Activities of the 21st Century; and he received the 1988 Space Pioneer Award for Science and Engineering
from the National Space Society for this work. Dr. Mendell is currently detailed to the Constellation Systems
Program Office as Chief, Office for Lunar & Planetary Exploration,. He acts as a liaison between the scientific
community and the Program responsible for implementing the Vision for Space Exploration.
He is an Associate Faculty of the International Space University. At the ISU, he has led
Design Projects for an International Lunar Base (1988), International Mars Mission (1991), International Lunar
Farside Observatory and Science Station (1993), Vision 20/20 [a sampling of the future as
seen by young space professionals] (1995), and Space Tourism: From Dream to Reality (2000).
He belongs to several professional scientific and engineering societies. He is most active in
the International Academy of Astronautics, where he is currently serving on Academic Commission III;
and in the AIAA, where he has chaired the Space
Science and Astronomy Technical Committee and sits on the International Activities Committee.
He served on (and chaired) the Executive Committee of the Aerospace Division of
the American Society of Civil Engineers. He has been editor for nine technical
volumes and has published over 40 articles in professional journals and conference
proceedings. He is also author of numerous abstracts and short papers presented at technical conferences.
On February 1, 2010, the federal budget for Fiscal Year 2011
was released. NASA received an increase, unlike almost any other federal agency.
At the same time, the budget revealed that the Constellation Program would be cancelled
and that NASA would look to private sector providers for transportation of cargo, and
eventually crew members, to the International Space Station. The Constellation Program
had included a human return to the Moon by the year 2020, and the program plans called
for a permanent surface facility capable of supporting human explorers.
In the FY2011 announcement, the prescription of a lunar objective was
replaced by a concept called “flexible path” that was
advertised to open possibilities of other types of human missions beyond low
Earth orbit.The policy direction has polarized the U.S. space community, where the
reactions have been swift and polemical. The new policy has been described both
as the death knell of human space exploration and as the only hope to save human
space exploration. Some members of Congress have threatened legal action based on
the current law regarding appropriation of funds to NASA, which states that Constellation
cannot be cancelled without prior consultation with Congress. As might be expected,
some of the reaction is directly related to losses or gains of jobs in districts
associated with NASA facilities. However, various statements show high emotional
content, suggesting that personal belief systems have been challenged. Meanwhile,
many details of the new policy are not yet clear; and some aspects seem to be shifting
in response to political reaction. The final direction for NASA will not be known
until the FY2011 budget has been passed by Congress and signed by the President.
I will draw upon my 28 years’ of studying, writing, and speaking on the topic of
future human exploration beyond low Earth orbit to discuss the various issues at
stake and the historical context for the debate. My own work has had a central
theme of lunar exploration and development,
but I have also come to believe that human exploration will never be more than a
political sideshow until a significant economic sector can be created in space
off of the Earth. Disclaimer: The views presented will be my own and in no way
reflect official policies of the NASA.

▼ More Info
Robert Zubrin, formerly a Staff Engineer at Lockheed Martin Astronautics in Denver
is now president of his own company, Pioneer Astronautics. He holds Masters degrees in
Aeronautics and Astronautics and a doctorate in Nuclear Engineering.
He is the inventor of several unique concepts for space propulsion and exploration,
the author of over 200 published technical and non-technical papers in the field, as
well the non-fiction books 'The Case for Mars: The Plan to Settle the Red Planet and
Why We Must' (Simon and Schuster 1996), 'Entering Space' (Tarcher Putnam 1999), and
'Mars on Earth' (Tarcher Penguin 2003). He is also the author of the novels
'The Holy Land' (Polaris Books, 2003) and 'First Landing' (Ace 2001), and most
recently, the science-humor immigrant guidebook, 'How to Live on Mars' (Three Rivers Press, 2008).
He is a Fellow of the British Interplanetary Society and former Chairman of the Executive
Committee of the National Space Society. Most recently, he founded the Mars Society;
an international organization dedicated to furthering the exploration and settlement
of Mars by both public and private means. In that capacity, he personally led the
construction and operation of a human Mars exploration training station on Devon Island,
an uninhabited island in the Canadian Arctic 900 miles form the North Pole. Prior to
his work in astronautics, Dr. Zubrin was employed in areas of thermonuclear fusion research, nuclear
engineering, radiation protection, and as a high school science teacher.
In July 1989, on the 20th anniversary of the Apollo Moon landing,
the first President Bush called for America to renew its pioneering push into
space with the establishment of a permanent Lunar base and a series of human
missions to Mars. While many have said that such an endeavor would be excessively
costly and take many decades, a small team at Martin Marietta drew up a daring plan
that could sharply cut costs and send a group of American astronauts to the Red
Planet within ten years. The plan, known as "Mars Direct", has attracted
international attention and broad controversy, including coverage in such publications
as Newsweek, Fortune, The Economist, Air and Space Smithsonian, the New York Times,
the London Times, the Boston Globe and Izvestia. It has also been covered by the
Discovery Channel, PBS, ABC, NBC, CBS, National Public Radio, and the BBC.
Its principal author, Robert Zubrin, has presented it to such fora as the
International Astronautical Federation congress in Germany, and the blue ribbon
"Synthesis Group" headed by former Apollo astronaut General Thomas Stafford,
the Augustine Committee, as well as to various government officials, including
House Speaker Newt Gingrich, former NASA Administrators Dan Goldin and Mike
Now, with nation debating how to proceed with human space exploration,
the “Mars Direct” plan is more relevant than ever: Can Americans
reach the Red Planet in our time?

The first human mission to Mars will likely be humanity’s greatest
undertaking in space exploration in the 21st century. As with all expeditions,
its success will depend on planning. The first steps towards a human journey to
the Red Planet are already underway, as we explore extreme environments on Earth
and prepare for new journeys to the Moon, near-Earth asteroids, and the moons of Mars,
Phobos and Deimos. Dr Pascal Lee will discuss progress being made around the world,
from the Arctic to Antarctica, to achieve these milestones. He will examine in turn
the what, why, when, who, and how of a human mission to Mars. Specific lessons learned
from the NASA Haughton-Mars Project will be discussed.

Extravehicular Activities for Mars Exploration
Mr. Pablo de León Research Associate, Department of Space Studies, UND
Extravehicular activity is one of the most critical areas for planetary exploration.
On Mars, due to gravity conditions, dust contamination and a specific thermal scenario,
a special kind of suit is required to protect the astronauts. Since 2005 the Department
of Space Studies at UND has been researching in the area of planetary space suit systems
and developed the NDX-1 a Mars suit demonstrator which was tested on Earth under analog
conditions. As a result of these studies new developments are taking place and a series
of design improvements have been done to prepare a suit that can cope with the Mars conditions.
Since a space suit is just part of the extravehicular system, an integrated design of the
mission contemplating all different aspects of the tasks to accomplish, is required.
A new NASA grant is allowing the Department of Space Studies to develop a complete
minimal mission scenario including inflatable habitat, airlocks, rovers and space suit,
to attempt to address all the different problems related to a human mission to Mars.
A mission to Mars and return to Earth will take more than two years, possibly
a lot more. The travelers will be exposed to microgravity, radiation, and sensory deprivation,
and other space phenomena in amounts which have never been experienced or tested before.
For example, the longest stay in space microgravity on board the Russian space station Mir
performed by Russian cosmonaut-physician Valery Polyakov was 438 Earth days.
will address questions such how can astronauts survive this long duration trip in hostile
environments of space? How can they maintain their health for an acceptable level of performance?
What are those natural mechanisms which help people to survive in extreme environments?
Rygalov also will discuss available techniques and current research trends in human factors in space.
The status of NASA’s Constellation program has been in question since it was first proposed in 2004.
In the last year or two, its status had become even more questionable. The recent US budget included
the new NASA budget. The NASA Administrator, Chuck Bolden Said on February 1, 2010: “So this budget
cancels the Constellation Program.”
David Whalen (background), Michael Gaffey (budget analysis),
and James Casler (Business and Management) of the Space Studies Department at UND will discuss this
shocking—but not surprising—announcement and its implications. This will be followed by Q&A and general
discussion. All are welcome to attend.

The Planet Mars
Dr. Mike Gaffey Chester Fritz Distinguished Professor, Department of Space Studies, UND
The planet Mars has been long identified as a target for human
space missions and possible human settlements. Since the 1986 discovery of possible
– but very controversial – microbial fossils in the Martian meteorite ALH 84001,
a fleet of unmanned spacecraft from several nations have visited the Red Planet.
Although many questions remain to be resolved, we now know a great deal more about
Mars than we did in 1989 when NASA, at the request of the President, outlined a
scenario for a manned Mars mission. In this presentation we will outline the present
state of knowledge concerning the nature and history of the planet Mars, with a
special focus on aspects which would impact planning for a manned Mars mission
and future human settlements.
Developing space resources or a space business venture requires capital.
Lots of it. Especially early on in the life cycle of a new business. While there
are some differences in a space business as compared to a terrestrial business,
there are many more similarities than one might believe. In fact, business rules
are pretty much business rules be it a space business of some type or a terrestrial
business in an established industry. While business planning and due diligence are
common, even routine in evaluating and managing terrestrial businesses, this is not
so in some areas of space, particularly with the NewSpace industry. What makes NewSpace
different? Why is it so hard to do real due diligence regarding all aspects of the
business, not just for management or potential markets, but also technical and
engineering due diligence regarding the end product of the company in question.
Why does the wish list mentality prevail and why are those applying real standards
to claims, rhetoric, and Power Points often attacked and accused of not being with
These and other issues such as assumptions making and commonly
used foolish terminology and rhetoric will be discussed in this presentation.
SpaceX is revolutionizing access to space by developing a family of launch
vehicles and spacecraft intended to increase the reliability and reduce the cost of
both manned and unmanned space transportation. This presentation will highlight
the details of the Falcon 1 (F1), Falcon 9 (F9) and Dragon programs that SpaceX
is currently undertaking.
On September 28, 2008, the Falcon 1, designed and manufactured from the
ground up by SpaceX, became the first privately developed liquid fuel rocket to
orbit the Earth. Details of the F1 vehicle will be presented along with video from
the first flight.
As a winner of the NASA Commercial Orbital Transportation Services competition
(COTS), SpaceX is in a position to help fill the gap in American spaceflight
to the International Space Station (ISS) when the Space Shuttle retires in 2010.
The Falcon 9 Launch Vehicle is the platform that will be used to provide access to
the ISS. Details of the design, manufacture and testing of the F9 vehicle will be
presented along with a video of the nine-engine, full duration test performed in our
McGregor, TX test site.
The Dragon spacecraft is made up of a capsule and trunk used for Earth to
LEO transport of cargo and/or crew members. Details of the design, manufacture
and testing of the Dragon capsule will be presented along with samples of PICAX
(a SpaceX developed heat shield material).
In his two talks beginning at 4.00 PM, Dr. Narain will first
trace the history of India's remote sensing program and then
follow it up with a presentation on India's recent unmanned
moon mission. India's space program has made significant
progress over the years in launch vehicle development, pay
loads for communication and remote sensing, and recently
joined an exclusive club of few countries that have capabilities
to orbit and study the moon. Much of this has been
achieved by the various centers of the Indian Space
Research Organization and technology transfer to the private
industries. The talks will cover how India's space program
has resulted in societal benefits through management
of natural resources, tele-education and tele-medicine.

Why Go to the Moon? The Many Faces of Lunar Policy. What is it about
the Moon that captures the fancy of Humankind? A silvery disk hanging in the night sky,
it conjures up images of romance and magic. It has been counted upon to foreshadow
important events, both of good an ill, and its phases for eons served humanity as
its most accurate measure of time. This paper discusses the Moon as a target for
Human exploration and eventual settlement. This paper will explore the more than
50-year efforts to reach the Moon, succeeding with space probes and humans in
Project Apollo in the 1960s and early 1970s. It will then discuss the rationales
for spaceflight suggesting that human space exploration is one of the least
compelling of all that might be offered. The paper will then discuss efforts
to make the Moon a second home, including post-Apollo planning, the Space
Exploration Initiative, and problems and opportunities in the 2004 Vision for Space Exploration.
T Tauri stars are low mass, pre-main sequence stars, many of which are still surrounded
by active accretion disks where it is believed planet formation is currently under way. Stellar
magnetic fields including a strong dipole component on these newly formed stars are believed
to play a critical role in the early evolution of the young star plus disk system. It is
currently believed that the stellar magnetic field truncates the accretion disk several
stellar radii above the star. This action forces accreting material to flow along the
field lines and accrete onto the star at high stellar latitudes. It is also thought that
the stellar rotation rate becomes locked to the Keplerian velocity at the radius where
the disk is truncated. I will review recent efforts to measure the magnetic field
properties of T Tauri stars, focussing on how the observations compare with the
theoretical expectations. A picture is emerging indicating that quite strong fields
do indeed cover the majority of the surface on young stars; however, the dipole
component of the field appears to be alarmingly small. I will also briefly discuss
recent work on the origins of magnetic fields in fully convective stars such as T Tauri stars.
Saturn's moon Titan is larger than the planet Mercury and has a dense atmosphere like a planet.
Until Cassini and its atmosphere-piercing radar got to Saturn little was known of Titan. Now with ~30%
of the surface revealed Titan is seen to have a very young surface, with deserts of dunes, rivers,
and hundreds of lakes and a few large seas of liquid methane/ethane. We can infer that Titan is
dynamically active, possibly with erupting volcanoes, blowing sediments, rainfall and rising
and falling lake levels. In the debate about what is a planet, Titan would be considered a
planet in all ways - except that it orbits another one.

Shedding Light on Dark Energy
Dr. Wayne Barkhouse Assistant Professor for the University of North Dakota (UND) Department of Physics
One decade ago, the astrophysics community was shaken to its core with
the announcement that the expansion rate of the Universe was speeding up
rather than slowing down due to gravity. This discovery - corroborated
at the time by two independent teams searching for supernovae -indicates
that the Universe is filled with a mysterious negative pressure or
"Dark Energy". For the past 10 years, theorists have invoked numerous
mechanisms to help explain this force, including Einstein's cosmological
constant, extra dimensions, quintessence, and even hypothesizing the
breakdown of General Relativity on cosmological scales.
To acquire a deeper understanding of dark energy, the Dark Energy Task
Force (jointly commissioned by NASA, DOE, and NSF) has recommended that
an aggressive program be established to fully characterize dark energy.
A part of this process includes support for a new large-area,
ground-based optical survey to chart the position and brightness of
several hundred million galaxies out to a redshift of order unity. The
leading contender that will satisfy these requirements is the Dark
Energy Survey (DES).
The DES is a 5000 square degree photometric survey that will image the
South Galactic Cap in multiple filters (griz), using a new 3 sq. deg.
CCD camera mounted to the Blanco 4-meter telescope in Chile. The nature
of dark energy will be probed utilizing four independent but
complementary techniques: the redshift distribution of galaxy clusters,
weak gravitational lensing by large-scale structure, the angular
correlation of galaxies as imprinted in the baryon acoustic
oscillations, and supernova distances. As a member of the DES, I will
explain how these techniques will allow us to unravel the mystery of

Melchor J. Antuñano, M.D., M.S. has been the Director of
the Federal Aviation Administration (FAA) Civil Aerospace Medical Institute (CAMI)
since January 14, 2001. CAMI is located at the Mike Monroney Aeronautical Center
(MMAC) in Oklahoma City. Dr. Antuñano provides executive
direction and is responsible for the administrative oversight of FAA Office
of Aerospace Medicine's programs in Medical Certification, Medical Education,
Medical Research, Human Factors Research, and Occupational Health Services,
that are critical and integral elements of the Office of Aviation Safety (AVS).
He is the focal point in leading the activities of a professional, technical,
and clerical team engaged in the policy development, planning, evaluating,
and administering of: 1) a program to fulfill the medical certification needs
of approximately 620,000 holders of U.S. pilot certificates, 2) a program for
the selection, designation, training, and management of about 5,000 Aviation
Medical Examiners (AMEs) appointed to conduct physical examinations and issue
FAA medical certificates to pilot certificate holders throughout the U.S.
and in 93 countries worldwide, 3) medical education programs in aviation physiology,
global survival, and aviation human factors for FAA flight crews and civil
aviation pilots, 4) medical publications and other didactic materials used to
disseminate medical information to promote aerospace safety, 5) a highly
specialized library system in support of a broad range of aerospace medical and
safety reference/research programs, 6) an integrated program of field and
laboratory performance research in organizational and human factors aspects of
aerospace work environments, 7) an applied research program to identify
human tolerances, capabilities and failure modes (physiological, psychological,

incidents and accidents, 8) an occupational medicine program to improve the
safety of FAA employees, and 9) a medical clinic that provides health
services to employees and students at the MMAC.
This presentation will discuss a number of physiological,operational,
and environmental risk factors (actual and potential) for the occupants of
commercial space vehicles. Actual risks include exposure to: 1)
High acceleration of flight profiles, 2) Decreased barometric pressure,
3) Microgravity, 4) Solar and galactic cosmic radiation, 4) Noise and vibration.
Of particular concern are the effects of exposure (short-term and long-term)
to microgravity on the cardiovascular, neurological, endocrinological, muscleskeletal,
and gastro-intestinal systems, among healthy and diseased passengers.
Furthermore, U.S. and Russian experience regarding space physiology and
medicine involve short-term and long-term space flights but does not address
the effects of: 1) Frequent repetitive exposure (several times a week) to
flight profiles involving: normal gravity (pre-flight) - acceleration (launch/take off)
- microgravity (space) - deceleration (return) - normal gravity (post-flight),
2) Frequent repetitive exposure to solar and cosmic radiation, and 3)
Exposure to microgravity among individuals who have medical pathology.
Other potential risk factors include unexpected exposure to: temperature
extremes, in-flight cabin fire, cabin air contaminates, electricity,
non-ionizing radiation, mechanical hazards, impact forces during crash
landings, post-crash fire, emergency evacuation, and post-evacuation survival.

Potential benefits of international space cooperation include access to unique
capabilities or expertise, increased mission flight opportunities, access
to program-critical locations outside of the United States, cost-sharing,
and building or reinforcing positive international relations among nations.
To date, NASA has concluded thousands of agreements with over 100 nations
and international organizations. In January 2004, President Bush announced
the new Vision for Space Exploration, and NASA was directed to pursue
opportunities for international participation in support of the U.S. Government's
new goals for human exploration of the Moon, Mars and beyond. As NASA implements
the Vision, the Agency is promoting new international space cooperation with
its foreign space partners in areas of mutual interest, through a variety of
bilateral and multilateral mechanisms. At the same time, NASA will continue

This presentation illustrates the outstanding achievements of the USSR,
and later Russia, in the study and exploration of space during the past century,
including the flight of the first artificial Earth satellite and orbital station
MIR. It outlines man's eternal dreams of fathoming the mysteries of the Universe
and the process whereby leading Soviet scientists developed and brought to fulfillment
the theoretical and practical principles of cosmonautics. Most of the presentation
describes and illustrates the various stages of preparation and training for
cosmonauts and the carrying out of manned space flights of different durations,
starting from the first in history, accomplished by Yuri Gagarin and finishing by International Programs at ISS.
At the same time that the U.S. and the Soviet Union started their space programs,
several countries in South America were also willing to enter the space race to a lesser degree.
