4 Activity 1 Introducing Space Exploration - Individual Research This activity fulfills some or all of badge requirements 1 and 2 (Option 1). Since taking their first steps on the planet, mankind has been looking to the skies. Around 1,000 years BC, the Babylonians - the earliest known astronomers - mapped the stars, believing that their fortunes were influenced by the patterns and positions they studied. Since that time, our knowledge of the stars and planets has been advanced by some of history s most prominent scientists, among them Copernicus, Galileo, Newton and Einstein. Visit the Agency s Discover and Learn webpages to prepare yourself for the discussions you re going to have about the fascinating world of space exploration and how far we ve come in the past six decades. DID YOU KNOW? Technology made for space exploration and space travel has also led to inventions on Earth. For example ear thermometers, fire fighters clothing, racing bicycles, computer game controls, scanners in airports, smoke alarms and barcodes were all developed from technology used in space. Activity Cut out the cards and place in chronological order. This will show you how the field of space exploration has progressed over the last 20,000 years. November 1957: Russian dog, Laika, becomes the first creature to orbit the Earth 1668: Sir Isaac Newton builds the first reflecting telescope. This new telescope design overcame the problem of false colour produced by refractor telescopes. Over 300 years later, Newton s invention formed the basis of the Hubble Space Telescope. 1473: Copernicus proposes a theory that replaces the Sun rather than the Earth as the centre of the Universe. 1981: The world s first reusable spacecraft, the space shuttle, makes its first flight. 1924: Edwin Hubble discovered that our Milky Way was not the centre of universe, but rather only one galaxy in among billions. 120 AD: Greco-Egyptian astronomer Ptolemy, compiles a star catalogue and makes careful measurements of the movements of planets. Ptolemy wrongly places Earth at the centre of the Universe. October 1957: The Soviet Union launches the first artificial satellite, Sputnik : The two Voyager probes are launched. These are sent out to explore the four gas giant planets of our outer Solar System, Jupiter, Saturn, Uranus and Neptune. They are now the furthest man-made objects from Earth. 1997: The Cassini-Huygens spacecraft in launched. This mission aims to study Saturn, its rings, its moons and its magnetic field. 1961: The Soviet Union launches cosmonaut Yuri A. Gagarin on a 108-minute flight. Gagarin becomes the first person to successfully orbit the globe. 1965: Russian cosmonaut Alexei Leonov goes on a 12-minute spacewalk. 1962: The UK gets involved in space when it builds six instruments to go up on the first international satellite, Ariel BC: Aristarchus (Greek) stated that the Sun was the centre of the solar system. It was almost 1,800 years later that his theory would be widely accepted. 1975: US and Russian astronauts meet in Earth orbit, shake hands on live TV, and spend two days together. 1510: Nicolaus Copernicus s theories that the Sun is the center of our solar system are banned by the Roman Catholic Church. They had been published after his death. 1630: Galileo Galilei first used a telescope from lenses he made himself. He stated that the Sun was the center of the universe, for this he was persecuted by the Church who believed that God had placed earth at the centre of the universe. 2000: The first crew arrive at the International Space Station. 1990: The Hubble Space Telescope is deployed. 1969: Apollo 11 touches down on the moon, and Neil Armstrong and Edwin Buzz Aldrin, become the first men to walk on the Moon 1988: Professor Stephen Hawking publishes A Brief History of Time, the most influential book about space written in the last 100 years BC: Babylonians study astrology - the belief that people s lives were influenced by the stars - and invent the 12 signs that are still used today. Around the same time, the Greeks name most of the stars and the constellations, and the wandering stars, which we now know were planets, and the Romans named them after their gods: Mercury, Venus, Mars & Jupiter. page 4 Astronautics Badge Activity Pack

5 Activity 2 Write a Mission Report The UK is currently involved in the following space missions: 1. Cassini Huygens A mission to study Saturn, its moons, rings and complex magnetic environment 2. SOHO (Solar and Heliospheric Observatory) This is investigating the sun from its deepest core to its outer atmosphere and has told us lots about the solar wind, a stream of charged particles produced by the sun. 3. Gaia Gaia will provide a 3D map of the one billion stars that make up our galaxy, the Milky Way. 4. Galileo The first highly accurate global positioning system under civilian control. Used for SatNavs, landing aircraft and timing bank transactions. 5. DMC (Disaster Monitoring Constellation) This is a network of satellites that can take detailed images of any part of the Earth to aid relief efforts during natural disasters. For this activity, choose a mission and write a mission report using the template below. You can get more information to help you write your report on the UK Space Agency s Mission webpage: This activity fulfills badge requirement 2 (Option 1) DID YOU KNOW? The Herschel Space Telescope is cooled to C. This is because the Herschel telescope detects a special kind of light coming from galaxies called infra-red. By the time the infra-red light has come all the way from far-off galaxies the infra-red is very weak. The problem is that Herschel produces its own infra-red light and this is so strong it hides the weak infra-red from galaxies so that the telescope can t see it. It s like the galaxy is whispering in infra-red but the telescope is shouting so much infra-red that the telescope can t hear the quiet infra-red from the galaxy. The hotter an object is the more infra-red it produces, which is why people look bright white under infra-red cameras compared to their colder surroundings. To stop Herschel producing so much infra-red light it is cooled down to nearly 273 C. Now the telescope produces hardly any infra-red and it can now hear the whisper of infra-red from galaxies.

7 Activity 3 Build a Model of a Spacecraft This activity fulfills badge requirement 2 (Option 2) Your leader will give you model patterns to choose from so you can make your model spacecraft. But you don t have to stick to those. Why not look at some of the links below and choose your own mission spacecraft to model? Cassini-Huygens, SOHO, GAIA, Ariane rockets and more: James Webb Space Telescope Herschel Space Telescope Hubble Space Telescope Venus Express Model_Instruction.pdf International Space Station Activity 4 UNDERSTAND satellite dishes with two simple experiments Introduction Satellites are objects in orbit around a planet or other celestial body. Man-made satellites are used for several applications including navigation, disaster monitoring, weather forecasting and TV and radio broadcasting. Just over 50 years ago, in 1962, the UK worked with NASA on the first international satellite, Ariel 1, which carried six instruments for measuring the space environment. There are now more than 3,000 satellites in orbit, owned by more than 40 countries worldwide. page 7 Astronautics Badge Activity Pack

8 2. Repeat this with the torch and note which materials allow light waves to pass: a. From inside a plastic container b. From the opposite side of a window c. From inside a cardboard box 3. Now place the radio in the carboard box and wrap the box in tin foil. You can investigate the technology behind satellites with the following experiments: Experiment A How do radio waves compare to light waves? TV and radio broadcasting signals are sent as radio waves. With this activity you can learn about how radio waves compare to light waves in this activity. What happens to the sound now? 4. What conclusions can you make about radio and light waves? Each group will need: a torch a portable radio a clear plastic container glass e.g. a window a cardboard box aluminium foil (to cover the box) 1. Turn on the radio and tune it in to a programme. What happens to the sound when you put the radio: a. Inside a clear plastic container? b. On the opposite side of a window? c. Inside a cardboard box? Experiment B Investigating the shape of satellite dishes Why are most satellite dishes on people s roofs bowl-shaped, instead of flat? Your leader will help you do this experiment to find out. DID YOU KNOW? The Earth s very own satellite, the Moon, is drifting away. Every year the Moon moves about 3.8cm further away from the Earth. This is caused by tidal effects on the Earth. In return the Moon s gravity slows the Earth s spin. Consequently, the earth is slowing in rotation by about seconds per day per century. Scientists do not know how the Moon was created, but the generally accepted theory suggests that a large Mars sized object hit the Earth causing the Moon to splinter off. page 8 Astronautics Badge Activity Pack

9 Activity 5 Keep Satellites in Orbit This activity fulfills some or all of badge requirements 3c When two objects are in proximity to one another, an attractive force acts to pull them towards one another. This force is gravity. Imagine these two objects as the Earth and a satellite orbiting the Earth. The closer the satellite is to Earth, the greater the attraction due to gravity. This attraction causes the satellite to fall towards Earth. The speed of each satellite is adjusted so that it falls to Earth at the same rate as the curve of the Earth falls away from the satellite. The satellite is constantly falling but it never hits the ground, because the ground curves away from it. Swimming cap Button Screw eyelet Chipboard/MDF Rubber circles Small screw You can make a simple demonstration of orbits by creating a Gravity Well: Strong thread Equipment needed: Large flower pot with drainage holes on the lower side (approx. 30 cm diameter). Remove the bottom of the flower pot before the demonstration using a Stanley knife. Make sure the top rim of the pot is smooth. Swimming cap One piece of chipboard or MDF 30 cm squared Two circular pieces of rubber 1cm diameter (such as from an old tyre, or from a rubber sheet) One needle with a large eye e.g. tapestry needle One small screw One screw eyelet Strong thread e.g. fishing line or nylon sail string Rubber glue e.g. an epoxy resin Small button Several marbles of different sizes Instructions: 1. Glue one rubber circle to the centre top of the swimming cap and the other rubber circle directly opposite on the underside of the cap. Allow to dry. 2. Stretch the swimming cap across the top of the flower pot and over the rim. Centre the rubber circles. 3. Using the needle, thread the strong thread through the rubber circles. Tie a button to the end of the thread on the side closest to the top of the flower pot, to stop the thread going all the way through the swimming cap. 4. Screw the eyelet in the centre of the chipboard and the small screw just inside one corner of the board on the same side. 5. Pull the thread down through the eyelet, then through a drainage hole on the flower pot, before finally tying the string securely to the small screw to stop it unravelling. This should have pulled the swimming cap down to create a gravity well. 6. Spin a marble around the gravity well. The gravity well simulates the gravity field of the Earth. The marble represents a satellite. If the satellite, or marble, is travelling fast enough it can orbit around the centre of the gravity well. This centre represents the Earth. 7. Observe what happens as the marbles loses energy and its orbit distance decreases. They should see the speed of the marble increase. The force of gravity gets stronger with decreasing distance between the two objects. Therefore, a satellite orbiting closer to the Earth must travel faster to stay in orbit than a satellite in a higher orbit. 8. Investigate the interaction of two gravity fields, such as between planets in our Solar System. Each marble makes its own depression on the gravity well and hence has its own gravitational field. By spinning two marbles in the gravity well, Scouts should see that the orbits of each marble are affected by the other marble. 9. The dependence of gravity on mass can be demonstrated by lowering the depth of the gravity well. This illustrates a heavier planet than Earth. page 9 Astronautics Badge Activity Pack

10 Activity 6 build a model of the solar system This activity fulfills some or all of badge requirement 4 (Option B) Introduction Our Solar System contains the Sun, its eight orbiting planets and other celestial bodies that are under the Sun s gravitational pull, such as comets and asteroids. Mercury, Venus, Earth and Mars are the four terrestrial planets, with rocky, solid surfaces. Jupiter, Saturn, Uranus and Neptune are the gas giants. Comets originate from the Oort Cloud and Kupier Belt, beyond Neptune, while most asteroids orbit in the region between Mars and Jupiter. Solar System Credit: Nasa 1. Planet sizes in our Solar System Your leader is going to show you the relative size of the planets in our Solar System, using fruit. Guess which fruits you think represent each planet. Mercury -... Venus -... Earth -... Mars -... Jupiter -... Saturn -... Uranus -... Neptune -... If you were going to make a scale model including the sun, you would have to find a fruit to represent it that was a million times bigger than the fruit representing Earth. 2. Distances in our Solar System Your second interactive Solar System demonstrates the immense distances between features in space. Your leader will help set this up, but you could look online to find out the actual distances of the planets from the Sun in km or miles. Planet Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Distance from sun DID YOU KNOW? There are 160 moons in our Solar System. Jupiter alone has 63, while Saturn has 52. The main four moons of Jupiter are called the Galilean Moons, as they were the four moons seen by the astronomer Galileo. These moons are Ganymede, Callisto, Europa, and Io. Europa is the smoothest celestial object in our Solar System like a giant marble. It has water trapped under ice on its surface and may contain life. Finally, Io looks a bit like a pizza because of lots of volcanoes on it surface spewing out lava. page 10 Astronautics Badge Activity Pack

11 Activity 7 Become a Mars scientist Introduction One day Mars scientists hope that real samples of Martian soil will be brought back to Earth. At the moment ESA scientists and engineers are working on the ExoMars mission to put a European rover on Mars. This rover will study the geology of Mars and look for signs of past or current lifeforms. You can have a go at detecting life (microorganisms) in soil samples from Earth with the following activity. Remember: That microorganisms are living organisms too small to be seen. That some microorganisms produce carbon dioxide if suitable nutrients are provided. Write up your own experiment below: DID YOU KNOW? The red color of Mars is due to oxidized (rusted) iron in its soil. Mars s volcano Olympus Mons is the biggest in the solar system. It is three times higher than our Mount Everest. Artist s impression of the ExoMars Rover drilling for rock samples. Credit: ESA - D. Ducros Introduction (Purpose of the experiment).. Method (How you went about it make notes as you do the experiment to help you) Conclusion (What you discovered about each of the soil samples) Mars Express exploring the red planet Credit: ESA - D.

12 Activity 8 Make an Impact! You ve heard about meteorites and other space matter that has crashed into the Earth and caused huge craters (check out Barringer Crater in Arizona, US, and Busumtwi, in Ghana). But how big did those meteorites have to be to make such huge impressions on Earth? See for yourselves with this mock meteorite exercise that you can do in your own HQ. Write down and compare your results with other groups. Meteorite Height Diameter of crater Sketch of crater shape eg rubber ball DID YOU KNOW? The Leonid meteor shower happens at intervals of approximately 33 years, though the next one is predicted to occur in years after the previous one. It causes meteors to shower the earth at a rate of thousands per minute, and creates the overall effect of lighting up the sky The Hadley Crater on Mars Credit: ESA page 12 Astronautics Badge Activity Pack

13 Activity 9 mission x: train like an astronaut Astronauts need to be extremely fit, agile, dexterous and possess advanced communication skills. We should all aspire to be as fit and healthy as astronauts. Your leader is going to set up an experiment for you to see how astronauts have to face the mental challenges they will have to face in space. Record how you and your partner/team do with the tasks your leader gives you. In brackets after the time recorded, get another group or pair to judge how well you completed the task by giving you a mark out of 10, 1 for not very well, 10 for excellent. Task Eg Spoon equal amounts of sand into four jars Time completed barehanded (first attempt) Time taken with gloves (first attempt) Time taken with gloves (second attempt) Time taken with gloves (third attempt) 10 secs 20 secs 17 secs 15 secs 14 secs Time taken with gloves (fourth attempt) Life on Board Your Spacecraft Being in orbit is a special sort of freefall - so you and everything around you is weightless. But there are also many other things you may not be aware of that astronauts have to consider before they take off. Nearly every astronaut will experience space sickness, which could mean headaches, nausea and confusion. Weightlessness means there s less pressure on the spine, and every astronaut will grow about two inches. The design of the spacesuit actually takes this into account. Snorers on Earth sleep quietly in space, it s been found but less well. The International Space Station takes 90 minutes to orbit the Earth. This means astronauts experience 16 sunsets and sunrises every 24 hours. If an astronaut suddenly finds himself without a spacesuit on, they won t explode, which is what most people think instead the lack of oxygen will kill them, although they have about two minutes before this happens. Before that the astronaut may experience moisture from the nose and mouth boiling away, slight sunburn, a painless swelling of the skin and underlying tissues and the bends. Going to the loo isn t easy. Astronauts have to place themselves, and are often strapped, exactly in the centre of the space commode to do their business, which is then sucked out. Astronauts use adult nappies for space walks, launch and landing. page 13 Astronautics Badge Activity Pack

14 DID YOU KNOW? Astronauts undergo lots of scuba diving as part of their training. Scuba diving is as close as it gets to experiencing weightlessness on Earth for long periods of time. Astronauts can also train for weightlessness by going on parabolic flights. These flights involve a modified plane following the flight path of a parabola and create periods where the passengers are in free fall. Activity 10 Build a rocket! This activity fulfills some or all of badge requirements 3 and 4 (Option A) Before you build one do you know how a rocket is constructed? Match the terms listed below to the rocket diagram labels A G. Nose cone Fuel A Nose Nose cone cone Guidance B Guidance Payload Payload Fuel CFuel Fin Propellant injection pump Nozzle Guidance system Oxidant Propellent injection injection D pump pump Oxidant Oxidant E Propulsion System Propulsion System DID YOU KNOW? The first rockets were made 1,000 years ago in China. Robert Goddard launched the very first liquid-fuelled rocket in Fin Fin G Nozzle Nozzle Fin F Fin page 14 Astronautics Badge Activity Pack
