Another Mars mission comes to a close

NASA officially brought the Phoenix mission to a close, as the U.S. space agency will cease operations and officially declare an end to the mission five months after it explored Mars.

The $428 million mission was originally scheduled for a three-month mission, but NASA was able to give it two extensions before the harsh Martian environment finally claimed it.  It has helped collect data on the northern arctic Martian plains, while helping collect valuable data that can be used for future missions.

"At this time, we're pretty convinced that the vehicle is no longer available for us to use," said Barry Goldstein, Phoenix project manager.  "We're actually ceasing operations, declaring an end to mission operations at this point."

Phoenix helped researchers learn some Martian soil is alkaline, and also helped confirm that ice may have melted on the Martian surface in the past.

The lander went quiet and has run out of sunlight necessary to power its batteries, while the temperature on Mars continues to drop.  Not completely unexpected, researchers still hoped they would be able to get another week or two of weather research out of the lander.

Engineers will have two satellites orbiting the Red Planet just in case the spacecraft responds, but NASA isn't optimistic they'll hear anything.  Even though the mission is over, researchers look forward to analyzing the large amount of data Phoenix helped collect during its mission.

"Phoenix has given us some surprises, and I'm confident we will be pulling more gems from this trove of data for years to come," said Peter Smith, Phoenix Principal Investigator working at the University of Arizona.

The last communication from Phoenix was received last Sunday.

No, they DO have two satellites orbiting Mars that will be listening in case the spacecraft responds.

Do you think spaceflight is so cheap now that we'll just toss out two new satellites today to listen in hope that a dead lander might re-awaken? Or do you just not bother to read the articles before posting them?

While his sentence may have been vague, it doesn't have to mean what you think it means. The sentence, 'Engineers will send two satellites....' would mean what you're saying his sentence means. But his sentence only states that at some future point there will be two satellites orbiting Mars, with no declaration about their current location.

In other words, the truth is both that engineers will have two satellites orbiting Mars (assuming no technical difficulties in converting between metric and imperial measurements again....), and 'they DO have two satellites orbiting Mars'.

Saying that "event X will happen" is contrary to saying "event x is happening". To make both statements correct at the same time, you must say "event x is happening and will continue to happen (or will happen again)".

Actually, now that I think about it, the sentence "Engineers will continue to have two satellites orbiting the Red Planet just in case the spacecraft responds" would have made sense.

While I agree it's a bit misleading, I believe he meant to say something along the lines of:

"Engineers have will have two satellites orbiting the Red Planet, listening, just in case the spacecraft responds"

or I could be completely wrong and that in the future, two satellites will be in the vicinity of Mars and be able to listen for a signal.

WTB jerks that understand the present perfect tense.

Yeah Surak, you need to chill. The quote is written based on Time of Event. It means, as it means to all the rest of us that read SOMETHING on a regular basis...

"by the time the spacecraft is on the sun side of the planet in a position to send a signal, two satellites will be present to pick up any readings"

Who cares if the article says that they will be or ARE there, if we already know that they are there?

It doesn't say that we will be sending satellites there in time to pick up the signal.


"We are going to continue to work with them to make sure they understand the reality of the Internet.  A lot of these people don't have Ph.Ds, and they don't have a degree in computer science." -- RIM co-CEO Michael Lazaridis
