You're welcome.

I'm blown away by the Pluto images right now and I can't wait for the upcoming pictures & data.

wait! they spent how much on this thing? and it can`t walk and chew gum at the same time?
doesn`t sending data use completely different hardware than collecting and saving data?

Did you read any of the thread? It has a fixed antenna for transmitting data back to Earth, and while it is taking photos ang gathering data, that antenna will not be pointed towards Earth....

Sorry, I can't 'remember' that BS because I never knew it. Take these conspiracy fantasies over to the UFOs and Aliens group.

When the little spacecraft has only enough power to light two 100watt light bulbs, you make compromises. One big one being no power left to have a motor to rotate the large gain antenna.

Simple spacecraft engineering and physics actually.

Embrace simplicity.

OK here it is in plain English NASA was created and is run by department of defense.

I am not buying any of it......there's no actual real time available for an important anything these days.....

Interesting. You are aware there is no such thing as "real-time" when you are over 5 light-hours away. That means that when a photo is taken and transmitted from New Horizons, we will not get it for 5 hours. That is not even close to real time due to a thing called physics and the absoluteness of the speed of light by the radio signal.

New Horizons has again communicated with Earth. It successfully passed by Pluto, and through its system of moons. Starting tomorrow, Wednesday, it will begin transmitting close up images and other scientific results back to us. It's estimated that it will take about 16 months to send the accumulated data, in full. Link to a news article with further details, below:

This is a dumb comment. The straight answer is that New Horizons was too busy being pointed at Pluto while it was gathering scientific data. Because it was pointed at Pluto, it was not able to transmit data back to Earth.

Besides, the bandwidth is very small. Even if it was able to transmit data back to earth while it was also collection data, the data collection rate far exceeds the transmission rate, so it would have been a while anyway waiting to get that specific data.

In fact, Pluto too so many pictures today (thousands, someone at Mission Ops said) and the bandwidth of the transmission back to Earth is so narrow, that it will take almost a year for the spacecraft to transmit all of the today's images and data collected today.

Ever have someone jabbering at you, while you are trying to concentrate?
that's pretty much why.

Tell it what to do, then let it do it.
Plus, I'm pretty sure the craft needs to be re-oriented to transmit. Which would cause it to lose valuable data collection time. They get ONE shot at this.

The New Horizons spacecraft can not collect data and transmitte it at the same time. It has to store the data and transmitte it later. At 1 Kb/s data transmission rate it takes 42 minutes just to send 2.5 Megabits of data. And it takes the signal 5 hours to get here.

That is what happens you are that far out with just a 12 watt transmitter.

As I mentioned above, I heard one of the mission specialist say that considering the MASSIVE amount of data and images collected today, it may take almost a year to be able to transmit all of the information collected today back to Earth.

No the dumb answer is the US government is corrupt yet NASA is this shining example of honesty, even thought it is part of the DOD.

I was going to say the wreckage of the Paladin, but not everyone would get that reference.

This sounds like a really poor design.

"Let's have our antenna point the same direction as the camera! Because...well...we want to transmit to what we're taking pictures of!"

"Bob, we're not taking pictures of Earth though, and we want to be able to talk to Earth..."

"So?! Just turn the whole darn thing around! It can't use that much fuel at those speeds!"

Uh, yeah. Maybe there's more to it, but as I said...it sounds like a really poor design.

Well, lets also consider that it's RTG (radio isotope generator) only generated 245 watts at launch, and that number decreases over time. That's not a lot of power to work with.

I'm actually kind of disappointed, we're essentially sending a paper airplane to Pluto. I know it costs a lot to get stuff off the Earth, but that's the biggest probe we could send? We couldn't send it up in pieces and have the ISS crew bolt them together, fire it off and get speed from slingshotting around Jupiter or something?

It sounds like a really clever design if you want to save money, weight, time required to build it, and reduce the risk of failure due to multiple motorised components. Can you please think first before you automatically assume the worst?

16 months? Geez... Each photo is going to be like the end of a GOT episode 'ahhhhh, what was that I wanna see more'... while we patiently wait.
