However, the United States and some other countries have resisted a formal, international delimitation of space, stating that it’s not necessary and that “no legal or practical problems have arisen in the absence of such a definition.” Others argue that maintaining a distinct boundary will be crucial, given an increase in the number of national space programs and in private spaceflight endeavors that are boosting the amount of suborbital traffic. “Once you agree on a boundary of space, you agree on a boundary where space law applies.” “Where does a country’s air space stop and space begin?” asks Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics. The laws governing air space and outer space are different flying a satellite 55 miles above China is just fine if space begins at 50 miles up, but define the edge at 60 miles, and you might find your satellite being treated as an act of military aggression. International treaties define “space” as being free for exploration and use by all, but the same is not true of the sovereign airspace above nations. Does it really matter where space starts? Here, we take a look at the ways space is currently defined, the confusion surrounding the demarcation, and what the future might bring. Is that a problem? “No, I think it’s great!” says NASA astronaut Mike Massimino, who helped repair the Hubble Space Telescope. As of right now, they will, according to U.S. Now, with Virgin Galactic seemingly on the cusp of launching paying passengers onto suborbital trajectories, many people are wondering whether those lucky space tourists will earn their astronaut wings. That might sound trivial, but defining that boundary could matter for a variety of reasons-including, but not limited to, which high-flying humans get to be designated as astronauts. It’s up, right? Simple.Įxcept, no one really knows where “air space” ends and “outer space” begins. You can expand upon them, or add your own twist.Ask someone where outer space is, and they’ll probably point at the sky. You can use them, but you don't have to use them. *Note: These craft ideas are just suggestions. Discuss how the planets rotate (spin) and revolve (move in a circle) around the sun. If enough students in your group, act out how the solar system works by assigning planets to each child, as well as someone to be the sun (or choose an object to be in the middle). Attach a craft stick or make 2 holes on either side of the plate and tie yarn so that the "helmet" can be worn.īrainstorm a new sentence to help remember the order of the planets. Students may need help making a hole in the plate. Use a paper plate to make an astronaut helmet by cutting out the center of the plate. Then use a black crayon to color lightly over the whole paper. Draw lines connecting the stars using a light colored crayon.ĭraw space objects on a white piece of paper or paper plate using crayons (press down hard). Use star stickers or draw stars on a black or dark blue piece of paper in the shape of a constellation and add a label. What shape is the sun? If the sun is a star, what shape do you think all stars are? (round or pointed) Solar system - the collection of eight planets and their moons in orbit around the sun, together with smaller bodies in the form of asteroids, meteoroids, and comets.ĭiscussion topics for during/after reading: Telescope - an optical instrument designed to make distant objects appear nearer, containing an arrangement of lenses, or of curved mirrors and lenses, by which rays of light are collected and focused and the resulting image magnified. Reflect - (of a surface or body) throw back (heat, light, or sound) without absorbing it: Satellite (as in a moon) - a celestial body orbiting the earth or another planet.Ĭonstellation - a group of stars forming a recognizable pattern that is traditionally named after its apparent form or identified with a mythological figure. If you could travel into space, what would you want to see or where would you go? What are some things that are in the solar system? Pluto was demoted from planet status some years ago, so there are only 8 planets in our solar system. It’s a reading adventure that’s out of this world! Grade Level: 1st (GLCs: Click here for grade level guidelines.)Īu revoir, Pluto! In this newly revised, bestselling backlist title, beginning readers and budding astronomers are launched on a wild trip to visit the now eight planets in our solar system (per the International Astronomical Union’s 2006 decision to downgrade Pluto from a planet to a dwarf planet), along with the Cat in the Hat, Thing One, Thing Two, Dick, and Sally.
