Help with these questions.
1. Describe a disadvantage of using a telescope positioned in space.
2. What advantage is there to doing laboratory experiments on the International Space Station rather than doing the same experiments on Earth?
3. Explain why it is unlikely that erraforming of Mars will occur in your lifetime.
Can someone please help me with these 3 questions?
Thanks.
1. They are more expensive than ground based telescopes and either a lot more difficult or simply impossible to repair or update. Also, they are vulnerable to various forms of damaging radiation and meteors. (I suppose the ground equivalent would be earthquakes and forest fires.) Other than that, no real disadvantages. Being outside the atmosphere they see more clearly. Many cannot be pointed near the Sun, but a lot of ground telescopes can't be used on the Sun either.
Motion is no more a problem than is the fact the Earth is moving a problem for ground based telescopes.
2. Microgravity allows near perfect crystal formation and through Einstein's Equivalence Principle, we are able to conduct complex research that might otherwise be influenced by gravity.
Microgravity provides an opportunity for experimentation in a whole new quiescent environment:
* no thermally-induced convection
* no sedimentation/stratification
* no hydrostatic pressure
* reduced contact with vessel walls
3. ... I don't know.
3. This is not my area of expertise, but how can we terraform Mars, if we are have a hard time terraforming Earth? We are fouling our own ecology.
I hope this helps. Thanks for asking.
Of course! I'm here to help you with your questions. Let's go through each question, and I'll explain how you can find the answers.
1. Describe a disadvantage of using a telescope positioned in space:
To find a disadvantage of using a telescope in space, you can start by considering some factors such as cost, maintenance, and limitations compared to ground-based telescopes. You can search for articles or research papers that discuss the pros and cons of space telescopes, such as the Hubble Space Telescope. By reading these sources, you'll be able to gather information about the disadvantages of space telescopes and describe them in your own words.
2. What advantage is there to doing laboratory experiments on the International Space Station rather than doing the same experiments on Earth?
To understand the advantages of conducting laboratory experiments on the International Space Station (ISS), you can explore NASA's official website or other reputable sources that discuss the research conducted on the ISS. Look for articles, videos, or interviews that highlight the unique conditions in space and how they affect scientific experiments. Pay attention to aspects like microgravity, vacuum, and radiation exposure. By analyzing this information, you can explain the advantages of conducting experiments on the ISS compared to Earth-based laboratories.
3. Explain why it is unlikely that terraforming of Mars will occur in your lifetime:
To address the unlikelihood of terraforming Mars in your lifetime, you'll need to consider both the technical and logistical challenges involved. You can start by researching scientific studies, space agencies' plans, and expert opinions on Mars colonization and terraforming. Look for sources that discuss the various obstacles, such as the lack of a breathable atmosphere, the absence of water in liquid form, and the overall complexity of drastically modifying an entire planet. Based on your findings, you'll be able to explain why terraforming Mars is considered highly improbable in the near future.
Remember, using reliable sources such as scientific journals, official websites, or reputable news outlets will help ensure accurate and trustworthy information.
