•Apollo 11 – the first manned mission to land on the Moon on July 20, 1969

•Americans Neil A. Armstrong (1930–2012), Edwin E. Aldrin Jr. (born in 1930), Michael Collins (born in 1930)
•“One small step for a man, one giant leap for mankind”
Technical estimation
•Command module computer built by Raytheon
•Apollo Guidance Computer (AGC) - simple commands by typing in pairs of nouns and verbs
•USB memory stick today is more powerful than the computers that put man on the moon
Curiosity. Mars mission.
Who's got six wheels, a laser and is now on the Red Planet? Me. I'm Curiosity, aka the Mars Science Laboratory rover.
The rover's goals include:
-investigation of the Martian climate and geology
-assessment of whether the selected field site inside Gale Crater ever has offered environmental conditions favorable for microbial life
-investigation of the role of water
-planetary habitability studies in preparation for future human exploration.
To contribute to these goals MSL has eight main scientific objectives:
1. Determine the nature and inventory of organic carbon compounds
2. Investigate the chemical building blocks of life.
3. Identify features that may represent the effects of biological processes.

Geological and geochemical
4. Investigate the chemical, isotopic, and mineralogical composition of the Martian surface and near-surface geological materials
5. Interpret the processes that have formed and modified rocks and soils
Planetary process
6. Assess long-timescale (i.e. 4-billion-year) Martian atmospheric evolution processes7. Determine present state, distribution, and cycling of water and carbon dioxide
Surface radiation
8. Characterize the broad spectrum of surface radiation
Journey from Earth to Mars
The rover was designed, developed and assembled at JPL in Pasadena (California)
Cost: 2.5 billion $
Assembly of the rocket-stages in “Vertical Integration Facility (VIF)” (distance to launch-pad: 0.5km)
Assembly of the fairing of the payload
•Atlas-booster with main rocket engine (RD-180): 4.150kN thrust
•Solid-booster: 4 x 1.690kN thrust
•Centaur upper-stage with RL-10-engine
•Atlas V 541
–5 diameter of payload fairing (4 or 5)
–4 number of solid-boosters (0 - 4)
–1 number of engines in the upper-stage (1 or 2)
•journey: 570 million km
•8.5-months-journey (254 days)
–Called “7min of terror” (beginning in altitude of 11km: 21,000km/h)
–Dampers (airbags) not possible because of too much weight of the robot (900kg)
–Very complex and dangerous
–Fully automated process because the signal from earth to mars takes 14min
–Destination: “Gale-crater”
Technical facts about Curiosity.
Curiosity Rover
-Mass – 899kg (in which 80kg of scientific instruments)
-2.9m long x 2.7m wide x 2.2m high
Power supplier
Curiosity is powered by a “radioisotope thermoelectric generator”. This is a power supply system which was successfully used in Viking 1 and Viking 2 Mars landers in 1976. It produces electricity from a plutonium-238. Use of this power generator makes Curiosity Rover independent from the solar light.
Heat-rejection system
Temperatures on Mars can vary from – 127°C to 40°C. Because of very sensitive components placed inside the rover it is very important to keep optimal temperature all the time. This is done by using about 60m of tubing into rover body that can both heat, or, if necessary, cool the Curiosity.
Curiosity is communicating with Earth mainly through Mars orbiters . These orbiters later transfer all the data to the Earth. To picture the distance between the Earth and Mars it should be enough to mention that the delay in communication varies from 4 to 22 minutes(depending to current planet’s position) – and data are ‘travelling’ with a speed of light. (300 000km/s)
Mobility system
Curiosity is equipped with six wheels in a rockie-boogie suspension and each wheel is independently actuated and geared. This rover can turn around in one place, ride above the rocks as big as its wheel , ride in the sandy surface of Mars or withstand a tilt of at least 50 degrees in any direction without overturning!
Scientific instruments
Mars Science Laboratory in numbers:
-2 500 000 000$ - estimated cost of the mission
-899kg – the weight of the Curiosity Rover
-687 days – estimated duration of the mission (possible to prolong)
-255 days – duration of the travel from Earth to Mars
-17 – number of cameras used in Curiosity
-10 – number of scientific instruments used in Curiosity
The Future of space exploration
1. The race for space conquest
• Manned lunar program
• Manned mars expedition
•Mars permanent base
•Lunar permanent base
•More than 8 launches in the next 10 years
• Manned lunar program
• Manned mars expedition
• More than 25 launches in the next 10 years.
• Launch of a chinese orbital base
• Manned lunar program
•More than 6 launches in the next 10 years.
• More than 16 launches in the next 10 years
2. The future technologies
<- Solar power satellite
Non rocket space launch ->
<- Solar sails
