The engineers began disabling the Phoenix devices

Gradually, NASA will turn off most of the devices and heating devices on the Phoenix spacecraft, until only one heater remains to operate one camera and the meteorological station * Update - communication has been lost and restored, the lander is in a safe state

Update - the connection with Phoenix was disconnected and renewed

In the news published this morning from NASA, it appears that at the end of Thursday, October 30, 2008, the communication between the Mars lander Phoenix and Earth, which had been interrupted a few hours earlier, was resumed. The connection that was renewed was not a direct connection with the lander but through the Mars Odyssey spacecraft which was also designed to be used as a relay station for the Mars landers. During the engagement, the engineers ordered the lander to switch to a careful work mode, designed to save energy. Mission engineers are assessing the condition of the lander and the steps needed to return it to full scientific operation.

The spacecraft suffered from a lack of electricity due to the reduction of energy production through the solar collectors caused by the reduction in the number of daylight hours and dust storms, as well as by extremely cold weather. The engineers were able to send a command to activate a dead battery. However, Phoenix did not respond to the Mars constellation's attempts to contact her on Wednesday night and Thursday morning.

The end of Phoenix is ​​near

The end seems near for the Phoenix Mars lander. On Wednesday of this week, the engineers began to turn off some of the spacecraft's instruments and heating systems. Although they are still convinced that by saving electricity it was possible to continue at least some of the missions, until the sunlight, whose hours are getting shorter with the arrival of autumn in the northern landing zone of Mars, runs out.

But right now, the spacecraft needs more energy to run its heaters in order to survive when the temperature drops. "If we do nothing, it won't take long until the electricity required to operate the spacecraft will be greater than the current required to operate the spacecraft will be greater than what will be available to operate its scientific instruments..." says the manager of the Phoenix program at NASA's JPL, Barry Goldstein . "By turning off some of the heaters and instruments we can extend the life of the lander by a few weeks and still perform some scientific missions.

This week the order was given to turn off one heater, the one that activates the robotic arm and the TEGA device - the famous heaters that contain systems for analyzing the composition of the gases. The meaning is to stop digging and baking the soil samples for the purpose of "perfuming" them. The engineers said that by closing the heater they would save 250 watts per hour. Before turning off the arm and the camera on it, the spacecraft took with this camera the last picture of the "holy cow" - an ice patch that is under the lander.

Over the next few weeks, four additional heaters will be shut down, one at a time, in an effort to conserve energy. The heaters are used for the purpose of keeping the electronic equipment in the field that allows it to survive. With each heater shutdown, some of the devices are expected to stop working. The energy you save is intended to operate the spacecraft's main camera as well as the instruments of the meteorological station until the absolute end of the mission.

Scientists and engineers are preparing for an eclipse in which the Sun will obscure Earth, as seen from Mars, a transit that will begin on November 28 and end on December 13. Mars and the Sun will be at an angle of two degrees from each other as seen from Earth. This eclipse will save the transmissions between the spacecraft and the Earth during this entire period. It will not be possible to send any new commands to Phoenix, but transmissions from Phoenix will be transmitted to Earth by the Mars Odyssey and MRO spacecraft. At this point, the controllers cannot predict whether the fourth heater is sitting before or after the eclipse.

After that, only one heater will remain to protect the remaining devices and the batteries. At this point, Phoenix will be at the mercy of Mars, says JPL's Chris LeWiki, lead mission manager.

The Phoenix team neatly parked the robotic arm in one of the excavations on the Martian soil. The devices mounted on the base of the arm were inserted into the ground and will continue to measure soil temperature and conductivity, along with near-surface moisture. The device does not need heating to operate and should continue to transmit data for several weeks.

During the entire mission, Midam's robotic arm dug and scraped soil from the landing area and brought the samples to the labs inside the spacecraft. "We shut down this workhorse, knowing that it exceeded all our expectations and performed every operation we asked of it," says Ray Arbidson, the robotic arm's principal investigator and a professor at Washington University in St. Louis.

  1. If there is wind, it can be used by a simple Shavet, it's not much, but still something.
    Perhaps there is a significant temperature difference between the ground and the air, this is also a possible potential for exploitation.
    I don't know the numbers, but maybe during the transition between day and night, even if it is very low temperatures, electricity can be generated by a substance that changes its state of aggregation in exactly this range.
    When we move to live there we will find more creative solutions.

  2. Why didn't they create a huge heavenly battery that would create a charge.
    And now really, it's a shame that the power in the spacecraft is mainly based on solar energy.
    Perhaps the soil of Mars or certain features in the atmosphere can be exploited to generate a higher electric current and over a wider time span. Any ideas?

  3. to anti-missile psalms
    You are probably wrong in a big way, and there is even a serious fear of blasphemy on your part, may God bless you.
    You must be asking why?
    Well. You must remember that all the things you call them
    "...talking and wasting money on acts of atonement.."
    are not done except, in honor of the creator of the world, with his permission
    And even the taste of the Holy One, blessed be He, will grow and be sanctified. After all, if the Holy One, blessed be He, did not desire them, then they are healthy and clear and understandable, above and beyond any shadow of doubt, even if it is the light of the light because, not only would they not have been done at all, but they would not even have arisen in the thoughts and imaginations of human beings at all And the Jews, in particular, who are the chosen and chosen among all of God's creatures and creatures, may he be increased and blessed and boasted and glorified and sanctified, blessed is he to the worlds forever and ever, God willing, I breathe.
    Now, when you come and claim and defy, accept the people and the world, in the phrase and in the letters of Kiddush Levane, Mercifully, against the holy deeds and the grace and the mitzvah and the desire and the consolation. The glory, majesty and wisdom of God Almighty's creators and messengers and doers of His commandments and will,
    You are not in your own name, God forbid, in the place of the mighty and terrible Almighty, the Holy One, blessed be He, in His own glory and in Himself, and this is nothing but the most terrible and terrible and abominable and insolent and dangerous blasphemy imaginable. And his end (your end?)…..Who will save us?
    Except if you turn back from all your wicked, contemptible, wrong, slanderous, blaspheming the name of the Holy King of Kings, blessed be He. And then, with the help of God, the Merciful, the Nerd, and the Beneficent. Our father, our kings, our rabbi and our teacher. The leader of heaven and earth, with grace and wisdom and grace and mercy, from then to eternity,
    Maybe, maybe, maybe, maybe, maybe, he will forgive and forgive you.
    Amen and amen. Yes, be pleased with him, the good benefactor, the wise and the merciful. Aman Sala.

  4. Psalms against missiles,

    I liked the nick :-)…

    We can also say:
    Psalms against lice.
    Psalms against Jews/Arabs/Poles/Yemenis.
    Psalms against elephants.
    Psalms against Psalms.
    Psalms against sperm.
    Psalms against rabbis.
    Psalms against secularists.

    In short... Psalms goes well against everything.

    post Scriptum. - Praise be to God, God truly protects us from all our pain/torts/haters/fills our needs/replaces our baby/shifts our gears and electrifies our electricity.

  5. Will it be possible to turn on all the devices that turn off in the future when there will be longer sunny days? Or everything that Maccabi has destroyed?

  6. Once again they talk and waste money on acts of heresy!!
    Only God will protect us and take care of all our needs!!
