Space Projects For Mr. Kelly\'s 4 th Grade Darren McKnight January 2006 NASA JSC Orbital Debris Program Office Web Site assets were utilized widely as a part of this report.

Slide 2

"Space Projects" Program Plan Background In each of the five task territories Five ventures to look over Launch satellites into space Satellite configuration Design a Mission to Mars Reduce orbital trash Reduce danger from articles returning to Earth For Mr. Kelly Only

Slide 3

How to Do Satellites Get Into Orbit? Gravity is continually pulling article\'s toward the focal point of the Earth g Earth Object must be moving sufficiently quick so it circumvents the Earth before it can fall g speed Earth

Slide 4

How to do satellites get into space? Article is in circle when it keeps on circumnavigating the Earth Anything that circles another divine body (e.g. planet, moon, and so forth.) is known as a satellite Earth

Slide 5

How quick is an Earth satellite going? An article that is circling the Earth is going around 7.5 km/s 22,000 mph!!!!! Could go to California and back in around 15 min About 400 times speedier than your auto on the thruway About 40 times quicker than a plane

Slide 6

Rockets used to dispatch satellites into space Rockets are utilized to dispatch satellites into space Get the satellite to a high height first Then turn the satellite opposite to the surface of the Earth Why? Escape thick air first to lessen drag Then get most extreme impact of rocket by swinging opposite to gravity speed g

Slide 7

What sort of satellites are dispatched into space? There are numerous sorts of satellites propelled into space Telescopes: why? Correspondences: why? Navigational: why? Spying: why?

Slide 8

Every satellite is comparative Every satellite has the same fundamental parts that can be contrasted with a human body Structure to hold parts together  ______________ Metal and plastic boxes, plates, and screws Computer to control satellite  ________________ When to move, when to convey, and so forth. Framework to power all the parts ________________ Batteries, sun oriented boards, atomic reactor, and so on. Covering to ensure all the parts  ______________ Foil, material, and so on. Drive framework to move satellite  ______________ Rocket, yo-yo, and so on. Frameworks to convey  _________________ Radar, transmitter, and so forth

Slide 9

Every satellite is comparative Every satellite has the same primary parts that can be contrasted with a human body Structure to hold parts together  Skeleton Metal and plastic boxes, plates, and screws Computer to control satellite  Brain When to move, when to impart, and so on. Framework to power all the parts Heart and lungs Batteries, sun based boards, atomic reactor, and so forth. Covering to secure all the parts  Skin Foil, material, and so on. Impetus framework to move satellite  Arms and legs Rocket, yo-yo, and so forth. Frameworks to impart  Eyes, ears, and mouth Radar, transmitter, and so forth

Slide 10

Spacecraft for people are distinctive Larger  Need more space for people to rest, work, and practice Oxygen framework  need oxygen supply for people to inhale Better assurance  can\'t be excessively hot or excessively frosty More solid  can\'t have anything turn out badly Need windows  people should have the capacity to glance around or they will be exceptionally uncomfortable

Slide 11

Debris in space Natural Debris Asteroids, Comets, Meteoroids, and Micrometeoroids Some go through the close Earth space Most are little – like sand Artificial (man-made) Space Debris (called Orbital Debris) Sputnik 1 dispatched October fourth, 1957 ~ 75 rocket dispatches every year ~30,000 extensive articles made since Sputnik ~10,000 still in circle Only 6% still utilitarian shuttle Remaining items are Orbital Debris

Slide 12

What is orbital flotsam and jetsam? Orbital trash is all space protests that are non-useful and man-made Fragmentation Debris (~1/2) Break-ups of satellites unused fuel, dead batteries, and so on. Creations of crumbling Paint drops, warm covers, and so on. Rocket Bodies (~1/5) Mission-related Debris (~1/5) Refuse from human missions Objects discharged from rocket Deployment and operation Non-Functional Spacecraft (~1/5)

Slide 13

Orbital flotsam and jetsam qualities French Cerise space apparatus struck by part from Ariane rocket body blast in 1996 ~ 11,000 items more noteworthy than 10 cm in measurement These articles are followed by the United States Space Surveillance Network utilizing radar and optical frameworks ~9,000 recorded items in both lower Earth circle (LEO) and geosynchronous (GEO) circles Will bring about cataclysmic harm upon effect ~100,000 objects somewhere around 1 and 10 cm Most are not followed objects since they are excessively troublesome, making it impossible to see with ground-based telescopes and radars Cannot be protected against nor moved around trash this size Many a large number of articles littler than 1cm Are not followed for same reasons as above - they are too little Many of these garbage can even now cause critical harm to rocket Crater on Shuttle window from remainders of a strong rocket terminating (i.e. sediment) that obliged window to be supplanted - $50k!!!

Slide 14

Orbital flotsam and jetsam does not leave… How long orbital trash stays in circle relies on the elevation of the circle a couple days if height is under 200 km a couple of years if height is between 200-600 km decades if height is between 600-800 km hundreds of years if height is more noteworthy than 800 km "always" if elevation is 36000 km or more prominent "Orbital lifetime" additionally relies on upon the qualities of the garbage and even the sun oriented movement Why?

Slide 15

Controlling Orbital Debris NASA Safety Standard 1740.14 NASA has received a strategy to control the era of orbital garbage All NASA flight ventures are currently required to give flotsam and jetsam appraisals as an ordinary part of the undertaking advancement. U.S. Government Orbital Debris Mitigation Standard Practices In 1997, the working gathering made an arrangement of U.S. Government Orbital Debris Mitigation Standard Practices . Taking into account a NASA wellbeing standard of methods for constraining flotsam and jetsam , the Standard Practices are proposed for government-worked or - secured space frameworks, including satellites and in addition dispatch vehicles . The interagency bunch has imparted the rules to the aeronautic trade to empower deliberate consistence .

Slide 16

What goes up must descend! Around 1 vast (greater than a softball) object returns to Earth from circle (deorbits) every day Most wreck in the air yet a couple tumble to the Earth One individual known not struck by flotsam and jetsam, however not hurt Probability is 1 in a trillion (1/1,000,000,000) of damage from orbital trash Risk because of lightning strike is 1 in a million (1/1,000,000) every year in the US Have you ever been struck by lightning? January 1997, Texas USA 500-pound stainless steel fuel tank, part of a Delta II upper stage rocket April 2000, Cape Town South Africa Pressurization circle

Slide 17

Potential Projects 1. Dispatch satellites into space 2. Satellite outline 3. Outline a Mission to Mars 4. Decrease orbital garbage 5. Lessen risk from articles returning to Earth

Slide 18

1. Dispatch satellites into space Problem : It is costly to dispatch satellites into space. As you have learned you should get a satellite going quick at a high height for it to "achieve circle". Challenge : Design another approach to dispatch satellites into space from the parking area of GBW.

Slide 19

2. Satellite configuration Problem : Satellites must be sufficiently extreme to be dispatched into space however have the greater part of the real parts as you found out about before: structure, PC, power, assurance, impetus, and correspondences. Challenge : Design a satellite whose employment it is to listen for signs originating from space and send this data back to Mr. Kelly\'s trailer at GBW.

Slide 20

3. Outline a Mission to Mars Problem : Americans have sent space travelers to the Moon yet now President Bush has said we will send people to Mars. Challenge : Design a shuttle to send Mr. Kelly, Ms. McNeilly, and Ms. Cleveland to Mars. Benefit a vocation, we need them back!

Slide 21

4. Diminish orbital flotsam and jetsam Problem : You have discovered that there is a great deal of won\'t (old satellites and parts) circling the Earth and representing a risk to working satellites. Challenge : Propose one or more approaches to keep the proceeded with expansion in orbital flotsam and jetsam and to expel orbital garbage that is as of now in space.

Slide 22

5. Decrease risk from articles returning to Earth Problem : Thousands and a huge number of pounds of metal satellites get dispatched into space each year and disposed of when finished with their main goal. In the end this material will fall back to Earth. Challenge : Propose new ways to deal with guarantee that the items that arrival to Earth don\'t hurt anyone on Earth.
