Earth orbit.

  1. A 100-kg astronaut (including the space suit) is stranded in space with only a large bag (50
    kg) of asteroid rocks (0.5 kg each). To get back to the exploration vehicle, she’ll have to
    throw the rocks in one direction to move in the other. If she can throw 1 rock per second
    at a velocity of 30 m/s, what is the specific impulse of her makeshift rocket? What is her
    thrust? What total ΔV can she generate?
  2. A remote-sensing spacecraft needs to correct its orbital velocity by 10 m/s. If the effective
    exhaust velocity of the orbital-maneuvering thruster is 1000 m/s, and the spacecraft’s
    initial mass including propellant is 1000 kg, how much propellant will the maneuver
    require?
  3. Rocket scientists are testing a new three-stage rocket for delivering small payloads to lowEarth orbit. It has these characteristics:
    • Ispstage 1 = 300 s
    • Ispstage 2 = 350 s
    • Ispstage 3 = 400 s
    • Payload mass = 1500 kg
    • Structure mass stage 1 = 10,000 kg
    • Structure mass stages 2 and 3 = 7500 kg each
    • Propellant mass stage 1 = 50,000 kg
    • Propellant mass stage 2 = 40,000 kg
    • Propellant mass stage 3 = 35,000 kg
    Find the total ∆V of the launch vehicle.
  4. What are three challenges associated with implementing design for manufacturing
    throughout a satellite’s life cycle and how might we overcome these challenges?
  5. Your SuperSat payload has a critical sensor that needs to operate in order to gather payload
    data. Each sensor has a reliability of 95%. Determine the overall reliability of your
    system for the following options:
    a. Single system (one backup part)
    b. Parallel (same design)
    c. Diverse design
    Which would you implement, assuming you had enough funding for three identical sensors?

Provide an overview of the stages of interviewing, including Exploration, Action, and Termination.
Explain the key skills to be employed at each of the three stages, their importance within the context of the consulting relationship, and related considerations such as the timing of the interview.

Describe your experience, for each skill you identified, by using or observing the skill in this course, including the emotions it triggered in you or obstacles that you had to overcome. Integrate these as real-world examples to share with the intended audience of your guide.
Consider how having diverse clients from different cultural backgrounds might affect your use of each of the skills you have identified (if at all). Specifically, compare and contrast how these skills would be applied to clients from two different cultural backgrounds.

Present a self-analysis in which you reflect on the skills you seem to have mastered fairly well and which you may need to work on. What are your strengths and areas for improvement, based on your experiences in this course? What values and dispositions do you possess that will undoubtedly serve you well while interviewing and are there any that might impede the process?
Summarize what you have gained from this course, and then explain how it may affect your future professional and personal relationships.

Government Agencies and Elected Officials

/in /by

1) Name, political party, years as president.

2) What was happening in history during this president’s term(s) that they had to deal with?

3) What was this president known for? Or what were the controversies or interesting stories about this president?

4) Did you know any of this before you did the research? Did anything surprise you?

5) What are your personal impressions of this president? Do you think you would have voted for them?

6) Where did you find this information? Provide your various sources.

If you choose a bureaucratic agency to profile, answer the following questions.

Go to USA.gov and look for a large federal agency. Click on Government Agencies and Elected Officials, then click on A-Z Index of US Government Department and Agencies.

1) Name of Agency, if a sub-agency provide the name of the larger agency (for example, the Bureau of Land Management is part of the Department of the Interior).

2) Provide the official website of the agency.

3) Who is the head of the agency? What is their name and title?

4) What is the mission statement (main purpose) of the agency. Look around the website and provide a review of how easy or difficult it is to navigate. Can you easily find what they do, or who to contact, or whether they are hiring?

5) In your own words, explain to the class what this agency is and what they do.

6) What did you find interesting, or what did you find out about this agency that you didn’t know about before?

Europe (Germany) in the early 20th century

/in /by

European artists working in the early 20th century drew inspiration from later 19th-century experiments with content, form, and color to create dynamic commentaries on the unique (and often
‘disruptive’) circumstances in which they lived. In consideration of the given image, please compose an interpretation* that includes the following points:

  • This painting reflects ‘expressionistic’ intentions (communicating emotions over objective reality). How does the image manifest a sense of ‘depression’ or ‘anxiety?’ Consider the mood(s) displayed by the characters, but also the artist’s distinctive style (treatment of form and space).
  • This painting was created in Germany in 1920. How do you interpret this subject matter in relation to its specific context? What does the artist communicate here about the ‘state of family and society’ in Europe during the modern era?
