Re: Mars Telecommunications Orbiter (MTO) - laser communication

We have actually brushed onto the MTO before with a topic of laser comunication and some references to it in as a next generation.

Lockheed milks Mars Space company expects to build another orbiter

Lockheed Martin Space Systems is expected to land a NASA contract to design and build the $500 million Mars Telecommunications Orbiter, which the space agency said will pioneer the use of lasers for planet-to-planet communication.

Known as MTO, the spacecraft is scheduled for launch in 2009 on a 10-year mission.

Lots of details.

Just wondering if it will make all 10 years of use before cancellation because nasa will need the money for the CEV to moon missions by that time?

GPS and  Internet for Mars.

Paving the way for efficient exploration.
I see it as a commitment to do considerably more on Mars.

Re: Mars Telecommunications Orbiter (MTO) - laser communication

:cry:  Sad to bring you guys this news
but they've been cost cutting with the Voyagers and now they have knocked down another mission



http://rockymountainnews.com/drmn/state … 68,00.html

Negotiations between the aerospace company and NASA had been expected to lead to the award of a design-and-build contract for the Mars Telecommunications Orbiter.
But the mission was canceled
"It's obviously a painful decision," Dantzler said Thursday. "We canceled MTO because we simply don't have the money in the future budget to support it."
Dantzler said the decision is final.





what's the problem with them ? :x

Re: Mars Telecommunications Orbiter (MTO) - laser communication

It all seems so ass-backwards...

Like they don't plan with long-term goals etc...
Or they keep Mars on th backburner, first Luna, then Mars, we'll get there when we're ready... ?


ExoMars' launcher's 2nd stage is probably en route to Mars. Unsterilised... yikes

Sound long term planning? From an agency of the United States government?

Now that's just crazy talk.  wink

Re: Mars Telecommunications Orbiter (MTO) - laser communication

Sounds like a little $500 million is more important than setting up the communications path for the next generation rovers which was a single unit in 2011 but which might not even turn into that at this rate.

Re: Mars Telecommunications Orbiter (MTO) - laser communication

First there was trouble with Hubble, Constellation, and JIMO and there seems to be a trimmed its request for future work on Project Constellation, which is intended to develop a Crew Exploration Vehicle - a CEV to the Moon and there was no funding for the Jupiter Icy Moons Orbiter (JIMO) mission for the budget effectively killing the program ?

Then we saw that they will try and Kill one of the most fantastic missions, the Voyager 1&2 program may be canceled. With Voyager we have possibly the only exploration of the outer heliosphere in our lifetimes then NASA officials told seven mission managers (Voyager, Ulysses, Polar, Wind, Geotail, FAST (Fast Auroral SnapshoT) and TRACE (Transition Region and Coronal Explorer) that there is now no money to keep their projects operating

Now the Red Planet is getting chopped down the Mars Telecommunications Orbiter could be axed and there have been reports on the newmars forum that it is cancelled. Placed at a much higher orbit than a satellite designed primarily for science and remote sensing is good, a dedicated relay satellite would be eclipsed for only a very small percentage of its orbit by Mars itself. This craft would be able to 'see' both the Sun and the Earth for effectively twice as long as a satellite in a low Mars orbit and it would double the time it can send data home to Earth and doubles the time its solar panels can soak up solar energy, giving it twice as much power to play with SMART-1 did carry out some trials in laser communications, demonstrating that a laser could track a spacecraft at lunar distances and communicate with it uses its Tereriffe laser facility to communicate with satellites in GEO and Europe is in a leading position in the domain of optical communications..
http://sci.esa.int/science-e/www/object … longid=862
Griffin begins to cut core missions of the Mars Program and reportedly wants to delay the Mars Science Laboratory (big nuclear powered rover) by two to four years. With No MSL and no MTO in 2009 that leaves the window completely empty for a NASA spacecraft. At a much higher  would also mean that any surface science packages or future-Rover on Mars would be able to see the orbiter for about half of its orbit, allowing potential data relay for about 50% of each day as opposed to 8 minutes for an orbiter in a MO type orbit or for even shorter in the planned lower MRO orbit. NASA cancels Mars telecom orbiter mission the Mars Telecommunication Orbiter is cancelled  all the money spent to date on the MTO is 100% wasted now . So NASA has cancelled plans to build a communications satellite that would orbit Mars and serve as a relay for future missions, a Denver newspaper reported that NASA scrubs Red Planet craft to save green.

Re: Mars Telecommunications Orbiter (MTO) - laser communication

While this is not the MTO of Nasa it is however about using laser beams to do high speed comunications.
There have been several release over the past few days with regards to a Dnepr Launch Vehicle sending "KIRARI" Optical Inter-orbit Communications Engineering Test Satellite (OICETS) into orbit. It appears that all is well and that they are in the testing setup phase.
Holding Mechanism Release of Laser Utilizing Communications Equipment (LUCE) on the Optical Inter-orbit Communications Engineering Test Satellite, Kirari, (OICETS) And Kirari and Reimei (INDEX) Entering Initial Functional Verification Phase

Now if Nasa is smart they will pay for the data on this and then make the appropiated decision to refund the MTO in the future based on this testing of technology.

Re: Mars Telecommunications Orbiter (MTO) - laser communication

Well, what can I tell you people?

You should be careful what you ask for when you said NASA needs to be reformed and the NASA budget needs to be reworked and re-prioritized as to what NASA spend there money on.

You might actually get what you were wishing for, but after you get it, it might not be what you wanted.

Such is life.

Larry,

If they don't need the bandwidth and NASA budget is stretched very thin it seems like a good fiscal choice to delay the MTO.

Re: Mars Telecommunications Orbiter (MTO) - laser communication

Back a while ago when the first round of project axe for missions that did not fit the immediate need for the vision there were a number cut including the MTO.

under the house committee document mentioned in the human folder.

24. With the cancellation of the Mars Telecommunications Orbiter, the conferees are concerned about how the requirements that led to the need for this mission will be met, especially optical communications. NASA is directed to provide a report no later than March 1, 2006, on these requirements, how it intends to meet these requirements and what the impact on the overall Mars exploration programmatic risk will be.

So in order for nasa to get its 2006 budget dollars they are going to need to explain why it was cancelled since they are the one that said that they would need it in the future.

Re: Mars Telecommunications Orbiter (MTO) - laser communication

Article not about MTO but is about laser communications.

Laser beams message between satellites

Two satellites have become the first to exchange information from different orbits using a laser . The feat may lead to super-fast data-relay systems between spacecraft.

One, a Japanese mission called Kirari (Optical Inter-orbit Communications Engineering Test Satellite), flies at an altitude of 610 kilometres, in low-Earth orbit. The other, a European satellite called ARTEMIS (Advanced Relay and Technology Mission), soars 36,000 kilometres above Earth in geostationary orbit.

Not quite the same as would be used for a mars to Earth repeater but without more testing of design we will never know if could make the distance and aiming acuracy that will be needed.

Re: Mars Telecommunications Orbiter (MTO) - laser communication

This is probably one reason for why the MTO has been cancelled at this point and hopefully it will be revived in time for manned missions to mars.

Longest laser link bridges the gulf of space

A laser communication link has been made across a record 24 million kilometres (15 million miles), between the Messenger spacecraft and instruments on Earth.

The craft and the ground station transmitted pulses back and forth to each other, and although no actual information was transmitted, the experiment shows the potential for interplanetary laser links.
