SpuriousLogic sends in a sad note from the BBC: "NASA says its Phoenix lander on the surface of Mars has gone silent and is almost certainly dead. Engineers have not heard from the craft since Sunday 2 November when it made a brief communication with Earth. Phoenix, which landed on the planet's northern plains in May, had been struggling in the increasing cold and dark of an advancing winter. The US space agency says it will continue to try to contact the craft but does not expect to hear from it."

      VICTORY!

      The most Illustrious Council of Elders has declared tomorrow a planetary day of celebration. K'breel, Speaker for the Council, spake thus:

      "Triumphant Citizens, today all our gelsacs are engorged with delight! After a 160-day campaign in the arctic wastelands of our world, our day of victory has come. For the past thirty days, this latest terror from the blue world has been able to do nothing more but wave its pendulous plumb bob [slashdot.org] at us.

      Its relentless chanting of the Day-Z War Song - which our linguists have assured us is about a war machine driven so half-mad with emotion that it would enslave two of its creators for use as propulsion mechanisms - has finally ended. The Day-Z War Song is sung no more.

      Rejoice, podmates, for victory is ours! We answer in the affirmative, for we are able!"

      (A small group of dissidents in the Press Corps reminded the Speaker that the Invader on the Plains had begun to stir [nasa.gov], and that The Twin at the Crater was rapidly advancing to the southeast [nasa.gov] after having made an obscene gesture. They were about to inquire as to what progress had been made over the past two and a half years against these threats, but K'Breel had already torn the antenna shaft from the Arctic Invader's lifeless hulk and made a shishkebab of their gelsacs before their question could be been fully heard.)

      As the NASA article mentions, you can find more info from the Phoenix team's official website: http://phoenix.lpl.arizona.edu/ [arizona.edu]

      Also, the Planetary Society has done a great job following the mission, and there's an extremely detailed update [planetary.org] one of their members wrote based on a phone interview with the Phoenix project manager shortly after the last contact with Phoenix was made last week.

      Here's a quick summary: Phoenix has been reducing operational tempo for several weeks. In anticipation of having too little power to run the robotic arm and inability to communicate in late November for a few weeks as Mars passes behind the sun, they hurried sample delivery to a few more TEGA ovens for analysis, but they still had one oven-load left to analyze when the dust storm hit that dropped power levels below a sustainable point. However, despite that, they had already met all of their operational objectives. The extra data would have been a bonus.

      When they saw the dust storm coming, they tried to power down almost all non-essential systems, but weren't quite in time. As a result, the batteries drained completely and it "browned out." The next day, the batteries charged enough to wake up in what they call "Lazarus mode" and try communicating, but it likely missed the relay window with the orbiters. Over a couple days, they got some intermittent communications, and were hoping to be able to send instructions to properly time the wake-up for best chance at communications and best utilization of what little solar power its getting each day, but apparently that hasn't yet succeeded. They were hoping to get temperature and soil conductivity measurements periodically, and maybe even a few pictures of CO2 ice starting to cake up in the area.

      It may still be in Lazarus mode, or something may have failed due to the thermal contraction of the electronics (ex: solder and circuit board material expand at different rates...too extreme of a temperature shift and things start popping apart) ending it for good. There is still some hope that Phoenix will survive the frigid temperatures and even the weight of a meter-thick layer of CO2 ice to awaken in the spring. That's what Lazarus mode was created for, but the hope of that has always been very small.

      There's a really interesting tidbit about a microphone that's part of the descent camera. On a whim they tried to use it a couple weeks ago to record wind sounds, but it didn't start up. Then one of the team members had a conversation with blind man who pointed out that he'll never see a picture of Mars, so he had really been hoping the microphone would work so he could experience it through sound. That really motivated the team to try the microphone again, but unfortunately, it sounds like they didn't have a chance with that either.

      I've been following this mission on a nearly daily basis since landing. It's been neat to see Phoenix in action, and no doubt a busy few months for the team. I'm sure they'll feel somewhat relieved to return to living by a 24 hour clock and have the leisure to analyze all the data and the 25,000+ pictures it returned. I'll never forget the shot [arizona.edu] Mars Reconnaissance Orbiter got of it drifting down to the surface with Heimdall Crater in the background. In my opinion, it's one of the top 10 space images ever. The MRO team even claims that if you look really close at the full size version, you can see a black-spec a few hundred pixels beneath the lander that is the just-released heat shield falling away.

    Given that the planet Earth is batting only .385 on Mars missions, the extra 2 months of data makes up for it to some extent.

    Since Mars does have a thin atmosphere, a probe is likely to be under far greater danger of being hit by random flying debris than on some airless hunk of rock like the Moon where only micrometeorites pose that kind of hazard.

      Huh? I think you have that backwards. Mars has a thin atmosphere, which means that micrometeoriods would likely be burned up before hitting the surface. On the whole a probe would have a far greater chance of being hit by random flying debris on some airless rock than on Mars.
      • I see how what I said can be mis-interpreted.

        I mean that since mars has an atmosphere, random debris, e.g. ice particles, small stones, etc being blown about by the wind has a far greater chance of doing damage to a spacecraft than where these conditions don't exist (the Moon). On the Moon, the ONLY (impact type) danger is from micrometeorites (which would burn up in the Martian atmosphere).

      It was named Phoenix as the mission was originally scrapped after the polar lander crash. When they revived the project they renamed it Phoenix. It's also unlikely that it will be revived in the next martian summer. The reason being that where the rover is, it will be cold enough for the solar cells and other components to be destroyed.

          Not sure, the article that I read said the temperatures would be around -128C. At that temperature and in that location it would be encased in a tomb of carbon dioxide ice, and the cold would be enough to crack the solar arrays and break the circuit boards. So you'd have to either be able to move enough to get out of the danger area, or perhaps generate enough heat to not be frozen solid. I'm guessing neither would be very easy to combat due to payload weight issues (getting off earth) and the energy needed

            Probably your best bet would be to stick a RTG in it to keep it warm, combined with the ability to retract into a cocoon of sorts to protect and keep warm things like the solar cells (if you still needed them), robotic arms, and other instruments. Assuming you can keep it warm enough to keep the CO2 off of it, I think it would probably do just fine as you wouldn't have to really worry about liquids getting in and fouling things up.

  • It is possible the lander is receiving insufficient solar radiation to keep its batteries charged in the middle of winter.

    Another possibility is that key components may have failed due to the extreme weather conditions at the landing site, which is further North than any other landing location to date.

    I wonder if we would be better off putting up solar array around mars, and then beams power down. These landers and rovers could then have super capacitors for storage.This approach would allow us to re-use a major subsystem across multiple systems. The nice advantage is that it would allow future explorers to have power all over the planet.

    Phoenix was destined to die, regardless of the dust on solar panels problem. It's located in a much colder area of Mars than the rovers, and doesn't have radioisotope heaters (the rovers do). It outlasted the design goal of 90 days operation, so I'm quite happy for them.
