Ugh, I can't find it! I just need a simple definition of what it is. Thanks.
I think you may well be referring to the technique of several radio telescopes some distance apart being used in such a way to act as a single huge antenna. The Very Large Array in New Mexico is an example of this.
Telescope Space Are there any man made objects on the moon viewable from the Hubble space telescope ?
It seems like we should be able to see the moon lander etc from the space telescope.
No the Hubble Telescope doesn't have the resolution but NASA has returned high-def pictures of all 5 Apollo landing sites. You can see man made structures plus astronaut foot paths. See below.
How big would a space telescope need to be in order to take images of earth sizes planet at ....?
least 30 year lights away? In comparison, how many times bigger would that be when comparing it to the Hubble space telescope?
At 30 LY (= 2.840 X 10^14 km), Earth's disc of dia. 12750 km appears at a angle(Radian) measure
4.49 X 10^-11 Radian
= (4.49 X 10^-11) X (180 / TT) = 2.572 X 10^-9 degrees = (9".26 X 10^-6)arc.
People want the aperture (of the telescope) in inches, so
Aperture (dia.of Objective lens) = 4.5 / (9".26 X 10^-6)
= 485954.4 inches
= 40496.20 feet
= 7.67 miles.
Anything more than this diameter only, will resolve the Earth's disc.
Astronaut Bio: Story Musgrave 8/97
Dear Geoff G,
Apparently you neglected to read the following details attached to my question:
"STS-61 was the first Hubble Space Telescope (HST) servicing and repair mission. Following a night launch from Kennedy Space Center on December 2, 1993, the Endeavour rendezvoused with and captured the HST. During this 11-day flight, the HST was restored to its full capabilities through the work of two pairs of astronauts during a record 5 spacewalks. Dr. Musgrave performed 3 of these spacewalks."
The repairs did not increase HST's ability for distance, just eliminated a problem in focus.
HST has photographed protogalaxies believed to be 13 billion lightyears from us.
Telescope Repair The space shuttle is in a 250 km-high circular orbit?
The space shuttle is in a 250 km-high circular orbit. It needs to reach a 580 km-high circular orbit to catch the Hubble Space Telescope for repairs. The shuttle's mass is 8.00×10^4 kg. How much energy is required to boost it to the new orbit?
first- convert km to m
second- use the equation E = GMm/2 *(1/ri)-(1/rf)
should look something like this
((6.67*10^-11)*(5.98*10^24)*
(8*10^4)/2) *
(1/(250000+6.37*10^6)-
1/(580000+6.37*10^6))
when i plugged it into my calculator, i got 1.144*10^11J (yes, it should be positive)
I am interested in building and repairing satalites and telescopes. What degree should I go after?
Tell me please!
You just answered a question with a question. It is best if you remain silent if you don't know the answer.
I think they hire a slew of diferent people, I know building a robot of any kind would require an engineer. And a space robot would benefit from phyicists cosmologists rocket scientists....
keep in mind the following source is trying to sell something and may not be reliable but here is what diplomaguide says about the subject:
Bachelor's degree programs in Satellite Engineering have not yet become common. Prospective satellite engineers should consider studying Mechanical Engineering, Electrical Engineering, Computer Engineering, Mathematics or Computer Science. Many advanced positions will require a master's degree in addition to an undergraduate degree.
