What does the technique of interferometry allow group of answer choices?
What does the technique of interferometry allow? A) It allows two or more telescopes to obtain a total light-collecting area much larger than the total light-collecting area of the individual telescopes.
What is the primary advantage of the Hubble Space Telescope over ground-based telescopes?
Space-based telescopes like Hubble get a much clearer view of the universe than most of their ground-based counterparts. They’re also able to detect frequencies and wavelengths across the entire electromagnetic spectrum.
What is the major advantage of an orbiting telescope?
It is because the images taken by a telescope from the earth’s surface gets affected because of the atmospheric layers and its composition. So it is difficult to obtain a clear image of the distant objects. But this becomes a major advantage of using an orbiting telescope because it provides clear and distinct images.
What are the disadvantages of a telescope?
- 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 is the most important factor to consider when purchasing a telescope?
The most important characteristic of a telescope is its aperture — the diameter of its light-gathering lens or mirror, often called the objective. Look for the telescope’s specifications near its focuser, at the front of the tube, or on the box.
Which technology is NASA developing that will help astronauts reach Mars?
Answer. The Mars 2020 rover mission has major new technologies that improve entry, descent, and landing: Range Trigger, Terrain-Relative Navigation, MEDLI2, and its EDL cameras and microphone.
Which object does NASA plan to design and use to land for astronauts to Mars?
Orion will carry astronauts into deep space, and then return them home safely to Earth. This spacecraft will take a crew to the Gateway in lunar orbit. The Gateway is a new spaceship that will serve as a place for astronauts to prepare before missions to the surface of the Moon and, ultimately, Mars.
What do astronauts carry with them?
Information about the items that astronauts take with them is usually kept very private, but typical PPK items include family photos, organizational flags, t-shirts, ball-caps, books, religious texts, and personal mementos.
Which is capable of housing astronauts?
A space station is capable of housing astronauts while they are conducting research. The space station is equipped with all the necessary tools and gadgets which help the astronauts to perform the research. It also has various communications devices to keep them connected with the local research bodies.
What rocket will take us to Mars?
About Orion Orion will serve as the exploration vehicle that will carry the crew to space, provide emergency abort capability, sustain the crew during the space travel, and provide safe re-entry from deep space return velocities. Orion will launch on NASA’s new heavy-lift rocket, the Space Launch System.
