  10. One Minute Reports: (8-28-12) • Do we pick our teams and what size are they? • Confused about what we do on team days? • Would I go to Mars if I had the chance? • When is the first assignment due and how do I get them? • What specific item will we cover the most in this class? • How do we make the final project? • Can I send mac files instead of microsoft files? • How do we go about creating our satellite? • Where did Hanz come from? • How much workload will we have?

  11. One Minute Reports: (8-28-12) • Can we do our volunteering through other clubs (Engineering Without Boarders) or Space Grant • Any projects aside from BalloonSat? • Will there be any field trips? • Just space or any aeronautics? • How do you pronounce Koehler and what do we call you? • To what extent do we need to know about satellites? • Will we really learn what some of those equations are?

  12. One Minute Reports: (8-30-12) • Do you think there is life in the saltwater of the moons of Jupiter and Saturn? • What did Jim for these missions? • Are there still any manned missions into space?Has NASA been permanently shut down? • How much does this all cost? • What are the most important missions we might work on when we enter the industry? • Is Pluto a planet or not? • Why will it take Curoisty 2 years to climb Mt. Sharp? • Do we ever miss the timing on intercepting a planet?

  13. One Minute Reports: (8-30-12) • Is there a worry that spacecraft may affect the orbits or the smaller bodies? • Is it possible to build a colony on the moon? • How do satellites get through the asteroid belt? • Why did they change the way they landed Curoisity? • Have they ever found a worm hole thing? • How do spaceships and satellites return to Earth? • Why are we going back to the Apollo style system? • What kind of people is NASA looking for for the next manned missions?

  14. One Minute Reports: (8-30-12) • How do you make sure the satellites get into Mars orbit not just slam into the planet? • How do they deal with the 14 minute delay on Mars Missions? • Why was there no updated pictures of Uranus and Neptune? • I’d like to see the rest of the videos.

  16. Spacecraft Overview Part I Class #3 Colorado Space Grant Consortium

  17. Updates Since We Last Met (November 4, 2009) Background image taken at 100,000 feet by a student BalloonSat

  18. Spacecraft Subsystems: Project Management Systems Engineering Comm Power Structures Thermal ADCS C&DH Ground Ops MOPS Education Web Science Software Teamwork

  19. Spacecraft Subsystems: Project Management Systems Engineering Comm Power Structures Thermal ADCS C&DH Ground Ops MOPS Education Web Science Software Systems You will have on your BalloonSat

  20. Solar Dynamics Observatory (SDO) Launched Feb 11, 2010 SDO is a sun-pointing semi-autonomous spacecraft that will allow nearly continuous observations of the Sun with a continuous science data downlink rate of 130 Megabits per second (Mbps). The spacecraft is 4.5 meters high and over 2 meters on each side, weighing a total of 3100 kg (fuel included). SDO's inclined geosynchronous orbit was chosen to allow continuous observations of the Sun and enable its exceptionally high data rate through the use of a single dedicated ground station. Sun in ultraviolet

  21. Mars Odyssey • Major Instruments: • Thermal Emission Imaging System (THEMIS) • Gamma Ray Spectrometer (GRS) • Mars Radiation Environment Experiment (MARIE) Launched: April 7, 2001 MOI: October 24, 2001 Controlled from Denver, CO Image credit: NASA/JPL-Caltech Odyssey Photos - Melas

  22. Size: Golf Cart Size / 400 pounds Landing sites on opposite sides of Mars. The mission was planned to last for 90 days each. The rovers were designed to travel up to 350 feet each Martian day, or sol (approximately 24 hours, 37 minutes). Image credit: NASA/JPL-Caltech video

  23. Say I Wanted You... To take pictures from space with this… • How would you do it?

  24. How… • Take a picture? • Power the camera? • Record the images? • Get the image? • Save the image? • Take an image of what? • Frequency of pictures? • Get pictures from space? • Point the camera? • I know it will work? • Keep it cool? • Cost? • C&DH/Software • EPS • C&DH/Software • COMM • C&DH/Software • Orbit/ADCS • Orbit • Launch vehicle • Structures/Mechanisms • Integration/Test • Thermal • Management The answers to these questions make up most spacecraft systems

  25. Questions Your Team Should Ask? • What does he want to take pictures of, how often, and when? • - What type of orbit would it need to be in? • How long would it take to get it to orbit? • How long would it have to work? • How do you know it will work when it gets there? • How much would it cost and how much would it weigh? • What would you have to worry about? • What would you need?

  26. What Do You Need? • Launch Vehicle • Temperature Control System • Communication System • Command and Data System • Structure and Mechanisms • Power System • Attitude System • Software • Propulsion System • Schedule • Budget • Plan • Testing • Reliability • Operators • People, People, People • Organization • Cash

  27. What To Worry About? • Radiation • Temperature Extremes • Vacuum of Space • Atmospheric Drag • Cleanliness • Launch Loads • Shock • Power • Mission Life • Autonomy • Cash • Pointing • Schedule • Weight

  28. The Process: (Chris’s Process) • 1. Mission – Thus the Mission Requirements (#7) • 2. Orbit Selection • 3. Launch Vehicle • 4. Everything else • - Structures, Interfaces, and Mechanisms • - Power & Thermal • - C&DH/Software • - Communications • - ADCS • - MOPS • - Other

  29. Remember Me?

  30. Orbit Selection: (#19 & #20) • Do you want to take picture of Boulder every day? • At the same time? • As many times as possible per day? • Pick orbit right up front • Different Types of Orbits • Polar Orbits • LEO • GEO • Different altitudes and inclinations • Sun Synchronous Orbits • - STK (Satellite Tool Kit)

  31. Launch Vehicle: (#15) • Then pick launch vehicle based on your orbit needs • Weight needs • Cost needs • Certain launch vehicles can’t go to all orbits

  32. Structure: (#25) • Your launch vehicle helps direct your structure design • Volume, CG, and weight constraints • Launch loads and shock issues associated with LV • Interface constraints • Vibration constraints

  33. Structure:

  34. Structure:

  35. Structure:

  36. Structure:

  37. Structure:

  38. Structure:

  39. Structure: • The whole purpose of the structure is to support the payload • Then the other systems • Composites • Honeycomb • Aluminum • Plate • Isogrid • Titanium • Stainless Steel

  40. Structure: • Design vs. Implementation

  41. Mechanisms: • In addition to structure you have mechanisms • People are afraid of mechanisms • Two types, deployment and payload support • They usually are single point failures • Hard to test on ground as they are used in space • Mast example (Special Programs, Balloon) • KC-135 Boom Video
