Excellent news: NASA May Launch Donated Spy Satellite Telescope to Mars. by Mike Wall, SPACE.com Senior WriterDate: 15 May 2013 Time: 04:30 AM ET [quote] The NRO's gift to NASA of unused spy satellites could enable a new project termed MOST, or Mars-Orbiting Space Telescope. ... As it's currently envisioned, MOST would have three main science instruments — an imaging spectral mapper, a high-resolution imager and an ultraviolet spectrometer — allowing it to make a broad range of detailed observations. The mapper would have a spatial resolution of 0.7 feet (0.21 m) per pixel at an orbiting altitude of 250 miles (400 kilometers), McEwen said. That's about 100 times better than the resolution achieved by a similar instrument aboard NASA's Mars Reconnaissance Orbiter (MRO), which has been circling the Red Planet since 2006. Hey, why not? As a spy satellite it was originally intended to look down on the ground on Earth, now it can still look down on the ground, on Mars this time. Launching so much long-term satellite equipment on the various Solar System bodies, like Mars, Jupiter, Saturn, Mercury, etc. are really putting our flag down on our ownership of this entire Solar System, not just Earth. Looking beyond Mars MOST would also be built to look up and out, beyond the Red Planet and its two tiny moons. The telescope's UV spectrometer is envisioned to be similar to that of the Hubble Space Telescope. But MOST likely wouldn't be able to study extremely distant objects as well as the famous HST, because installing a Hubble-like guidance and navigation system that allows a prolonged lock on such faint targets would raise the price tag significantly, McEwen said. Instead, MOST may be optimized to view planets and moons in the outer solar system. Yeah, who needs it? We're going to have JWST pretty soon too look at the long-distance objects anyways, this way you can concentrate JWST's resources on stuff outside the solar system, and this thing can look at stuff inside it.

It would be like sending a KH-11 or Hubble to Mars and would make MRO (a pretty big orbiter) look tiny. What kind of rocket are we going to send this to Mars on, SLS? How are we going to get back that much bandwidth of KH-11/Hubble class images from Mars? And wait until Henry Spencer and the CSA hear that NASA is trying to steal the "MOST" name... A more basic Earth-orbiting telescope is a far better use for this hardware. Brian |

Geez i suggested sending one of these to mars and was laughed at........ You were laughed at because you said such egregiously stupid things in conjunction with that 'suggestion'. My track record stands on its accuracy. could a shuttle get stuck at statiion,,,,,,,, laughter, then columbia, then nasa plans for a shuttle stuck at station hey there have been too many fying catches, too much schedule pressure, were going to a lose a shuttle... then columbia dies, cause? too much schedule pressure hey send a leftover spy sat to mars.LAUGHTER. Now they are taling of doing just that hey chemical propulsion for manned mars mission wouldnt work. Now bolden says the same. need I go on?????????? Meanwhile fred j cueless throws insults and offers nothing but useless noise |

Just take it easy Mr. No ownership of anything. It is not enough to send a satellite somewhere to OWN a celestial body like Mars! Anyway, other nations have sent satellites to other planets (the russians for instance would own Venus since they landed in there long time ago) The U.S. owns a small portion of the earth delimited by their frontiers, like all other countries on earth. They do not even own north america, since canadian and mexicans also own part of it. :-) Just take it easy. |

This is your perpetual problem, Bobbert. *You say something surrounded with idiotic ideas, people call you a moron, and later you only remember the one tiny similarity between what you said and what is happening. so do some research and prove it, search the archives provide links and post exactly I said that was idiotic...... my idea was to repurpose at least one of these spy sats for use in mars orbit. i was laughed at. your making the claim no prove it! |

The scope is light (two tonnes or so); I think the plan is to send it up on a Delta 4 with a solar-electric propulsion system on the spacecraft, and creep up slowly on Mars. Tom |

There is still however the minor issue of the maximum, practical, achievable bandwidth of a data link between Earth and Mars which is far less than that of Earth to Earth orbit. -- Jim Pennino |
