What are the disadvantages of ground-based telescopes?
Despite the convenience of ground telescopes, they do feature a few drawbacks that space telescopes don’t have.
- Lower Cost. Ground-based telescopes cost about 10 to 20 times less than a comparable space telescope.
- Maintenance Issues.
- Site Requirements.
- Image Quality.
- Deficient Data.
Why do we bother making space based telescopes?
The main reason we put telescopes into space is to get around the Earth’s atmosphere so that we can get a clearer view of the planets, stars, and galaxies that we are studying. Our atmosphere acts like a protective blanket letting only some light through while blocking others.
Are spacex satellites still visible?
Elon Musk’s space firm has currently more than 1,500 satellites in orbit and aims to get up to 42,000 up there by mid-2027. Most recently, Starlink satellites have been spotted over the UK, Ireland, and states in the US, including Arizona and California.
How do ground-based telescopes work?
When ground-based telescopes view stars, the light they collect must weave its way through layers of air. When those layers are turbulent, the light gets blurred, so images from observatories with large mirrors turn out no better than those from your backyard telescope. Adaptive optics corrects the problem.
What are the disadvantages of a telescope?
The disadvantages are mainly to do with the hassle of operating in space. It’s much more expensive, so you can’t have such a large telescope. If things go wrong it’s much harder to repair them. You can’t update the instruments so often so they quickly become out of date.
Which of the following is a problem with ground based telescopes?
Ground-based telescopes can’t do the same, because the Earth’s atmosphere absorbs a lot of the infrared and ultraviolet light that passes through it. Other space telescopes cannot be serviced this way.
What can telescopes in space see that we Cannot spot on Earth?
Space-Based Telescopes They’re also able to detect frequencies and wavelengths across the entire electromagnetic spectrum. Ground-based telescopes can’t do the same, because the Earth’s atmosphere absorbs a lot of the infrared and ultraviolet light that passes through it.
What is the major advantage of an orbiting telescope?
Space telescopes have the advantage of being above the blurring effects of the Earth’s atmosphere. In addition, there are many wavelengths from the electromagnetic spectrum that do not reach Earth because they are absorbed or reflected by the Earth’s atmosphere.
Is Starlink visible every night?
He said satellites can be seen during twilight, early evening and really late at night right before morning twilight when satellites in low orbits can be seen. When asked if Musk’s satellites would pique kids’ curiosity about astronomy, he said it may.
What are 5 disadvantages of a refracting telescope?
Disadvantages:
- Very high initial cost relative to reflector.
- A certain amount of secondary spectrum (chromatic aberration) unavoidable (reflector completely free of this) The colours cannot focus at one point.
- Long focal ratios can mean that the instrument is cumbersome.
What are 2 problems with refracting telescopes?
The two problems with refracting telescopes are a chromatic aberration and spherical aberration.
What makes a good telescope for land viewing?
Keep in mind that, compared to mirror-based telescopes, land viewing models mostly use lenses/refractors to present clear images. Whether you want a telescope that will allow you to zoom in on wildlife or for some other telephoto idea, you will need to take a couple of factors into consideration.

Why are space telescopes more expensive than ground based telescopes?
Ground-based telescopes can’t do the same, because the Earth’s atmosphere absorbs a lot of the infrared and ultraviolet light that passes through it. Nevertheless, space-based telescopes are expensive to build and difficult to maintain.
