Launch Services: The Science of SIRTF
Question Board

Blake from Hollywood, California
What kind of things can scientists learn from the infrared that they can't learn from other telescopes like the Chandra or Compton observatories?
Peter from Basel, Switzerland
Can SIRTF take photos of other planets like Mars, same as the Hubble Space Telescope?
Andy from Grangemouth, U.
They are saying that an Earth trailing orbit has never been used before, why now are they deciding to use it?
Ben from Brooklyn, New York
Why was an Earth trailing solar orbit chosen for SIRTF? (as opposed to an Earth orbit, or one that orbits the Sun away from Earth). Thank you, Ben
Hal from Boulder, Colorado
At what temperature will the mirrors operate and why are they at that temperature?
Rich O. from Elk Grove, Illinois
The images that SIRTF will be taking, how will they compare to Hubble? Will there be a comparison photo made of and object from Hubble and SIRTF so we can see the difference?
Brian from Elk City Town
What is the great thing of SIRTF that makes the great pictures that we can see for the science and for the beautiful of space and the universe?
Marcus from Toronto, Canada
As SIRTF looks for extra-solar planets, will it find hot Jupiters or terrestrial rocky planets?
Jeff from London
Is the asteroid that was announced last summer still on a direct hit with Earth? If yes when?
Elaine from Tampa
What do you think the most important part of this mission will end up being? What new discoveries can we hope to gain from this mission?
Juan Rodriguez from Gijon, Spain
What is the resolution of SIRTF pictures? Will we see the same detail, in infrared, as in the Hubble pictures? Thanks.
Juan Rodriguez from Gijon, Spain
Can SIRTF be useful to study the distribution of interplanetary dust in our solar system?
Juan Rodriguez from Gijon, Spain
Are you going to use SIRTF to study Kuiper Belt objects? What kind of information will you obtain if so? Thanks!
Juan Rodriguez from Gijon, Spain
Is there any specific plan to search for faint objects near our solar system (brown dwarfs, very low mass stars)?
Geoffrey from Kiowa
How will an Earth trailing orbit help SIRTF?
Tyler from St. Joseph
I am 11. If Mars, Venus, and Earth lined up would Mars and Venus have the slightest gravitational pull on Earth both ways? Please answer! This is very important!
Wes from Angus, Georgia
Hello I'm here to ask a question about a future NASA program that I watched on a video! Supposedly in 2023 NASA is supposed to launch a group of satellites that once in orbit will fly in laser guided formation around a larger telescope! After all this is complete it is supposed to let NASA look directly at a planet in another system inside of looking for the shimmer of a star to know if its there? How is that project going and are there any new updates about it? thanks Wes Hopkins
Jennifer from Edmonton, Canada
Will SIRTF be used to study black holes? If so, do you think SIRTF will give us a better understanding of black holes, how they work, and how they affect the universe?
Jennifer from Edmonton, Canada
Will SIRTF be sending images back to Earth, and/or computer data files with numbers and coordinates? Infrared light is invisible to the human eye, so how would the information be represented in images interpreted by astronomers and scientists?
Jennifer from Edmonton, Canada
How can interplanetary (sometimes called zodiacal) dust emit infrared radiation?
Jennifer from Edmonton, Canada
How will SIRTF be able to tell the difference between a piece of space dust only a few meters away and a faint star some hundreds of light years away? Will SIRTF have any way of judging the distance of the objects it will study?
