While bogged down at Troy, Spirit looked westward on the evening of sol 2,002 to watch the Sun set. Before it reached the horizon, the Sun vanished into dust kicked up in a regional dust storm.

The amount of electricity generated by the solar panels on Spirit has been declining for the past several Martian days, or sols, as a regional dust storm moved southward and blocked some of the sunshine at Spirit's location. The team operating the rover has responsively trimmed Spirit's daily activities and is keeping an eye on weather reports from observations by NASA's Mars Reconnaissance Orbiter.
Spirit's solar panels generated 392 watt-hours during the mission's Sol 2006 (Aug. 24, 2009), down from 744 watt-hours five sols earlier, but still generous compared with the 240 watt-hours per sol that was typical before a series of panel-cleaning events about four months ago.
"We expect that power will improve again as this storm passes, but we will continue to watch this vigilantly," said JPL's John Callas, project manager for Spirit and its twin, Opportunity. "Spirit remains power positive with healthy energy margins and charged batteries. The weather prediction from the Mars Color Imager team is that the storm is abating, but skies will remain dusty over Spirit for the next few sols."
Recent images from the Mars Color Imager camera on Mars Reconnaissance Orbiter showed this regional storm becoming less extensive Monday even as it shifted southward so that its southern edge covered the Gusev Crater area where Spirit is working. Malin Space Science Systems in San Diego, which operates that camera, provides frequent weather updates to the rover team. Weekly reports are posted at http://www.msss.com/msss_images/latest_weather.html .
Meanwhile, in JPL's In-Situ Instrument Laboratory, the rover team is continuing testing of strategies for getting Spirit out of a patch of soft soil where it is embedded on Mars. On Sol 2005 (Aug. 23, 2009) Spirit used its panoramic camera to examine the nature of how soil at the site has stuck to the rover's middle wheels. The team has also used Spirit's rock abrasion tool as a penetrometer to measure physical properties of the soil around Spirit by pressing into the soil with three different levels of force. The team is aiming to start sending drive commands to Spirit in September.

Это просто - я вас научу. Выходите ночью (желательно сухой и холодной) на улицу (лучше раздетым), закрываете глаза и стоите так несколько часов, повторяя про себя: "Марс, Марс, Марс, Марс..."
К утру поверите

А вот вам не надо вставлять палки в колесы прогресса. Этими людьми нужно восхищаться - это ж какое бабло народ в песочнице моет!
А ну как они выяснят, что спасение только в буксировке?! Подтянут второй марсоход, кинут конец...
Талант не пропьешь... Песня!
Да кабы у наших фантазии было побольше, наши Луноходы до сих пор бы ездили, доводя амеров до зеленой злости!

требуем повышения зарплаты CALTECHовцам и JPLовцам!!!
сразу после проверки аполлоновских камней...  :wink:

Любопытная статья. 16 июля MRO произвел фотосьемку застрявшего марсохода, и его местоположение оказалось немного в другом месте, чем ранее предполагалась на основе его собственных снимков.

Tests of possible maneuvers for use by NASA's rover Spirit on Mars include use of this lightweight test rover at NASA's Jet Propulsion Laboratory, Pasadena, Calif.

Tests on Earth simulating Spirit's predicament on Mars have reinforced understanding that getting Spirit to rove again will be very difficult.

To supplement the tests at NASA's Jet Propulsion Laboratory in Pasadena, Calif., the rover team is refining a detailed computer model of rover mobility, calibrated with results from testing and measurements from Mars.

"The computer modeling will allow us to connect the results from tests performed in Earth gravity with what to expect from the rover in Mars gravity," said JPL's John Callas, project manager for Spirit and its twin, Opportunity.

Spirit became embedded in soft soil at a site called "Troy" in early May, more than five years into a mission on Mars that was originally scheduled to last for three months. The rover team suspended further driving attempts with Spirit while evaluating possibilities from tests performed at JPL simulating the Troy situation.

An additional round of testing was added to the September schedule to gain more detailed assessment of how to move Spirit while avoiding putting the rover's center of gravity directly over a rock that is touching or nearly touching the rover's underbelly. Other added tests are using a lighter-weight test rover than the one used for most of the testing this summer. A complete "dress rehearsal" test of the extrication strategy judged to hold the best chance of success is planned in the test setup at JPL before the team commands Spirit to begin driving. That test and subsequent review of its results are expected to take several weeks. Moves by Spirit will not begin before October, according to current plans.

"We are proceeding very cautiously and exploring all reasonable options," Callas said. "There is a very real possibility that Spirit may not be able to get out, and we want to give Spirit the very best chance."

A dust storm that had reduced the electrical output from Spirit's solar panels by nearly half during late August still has some lingering effects on the skies above Spirit.

до ребят уже дошло, что в марсианском тальке роверы передвигаться не смогут?  или ещё нет? :wink:

эт вам не Аризона...

По слухам, начало операции по вытаскиванию Спирита назначено на 9 ноября

[Космос-3794]

NASA's Mars Exploration Rover Spirit провел более шести месяцев не проявляя симптомов амнезии, которые до этого четыре раза регистрировались в начале года. В каждом таком случае, роверу не удавалось сохранить данные дневной активности в энергонезависимой "flash"-памяти, которая позволяет сохранить данные во время энергосберегающего  периода "спячки". Повторное возникновение этих симптомов в последние дни может отложить старт планируемой операции по вызволению  ровера из песчаной западни.
Данные переданные Спиритом с 24 по 27 октября показывают что flash-память не использовалась. Ровер имеет также альтернативную память (RAM) данные в  которой могут сохраняться если сессия связи проводится до периода "спячки". Спирит остается на связи с Землей, поддерживая достаточную мощность питания и   температуру.
Мы не знаем что является причиной этих приступов "амнезии", говорит John Callas менеджер проекта MER.
На этой неделе независимая комиссия экспертов изучала результаты испытаний и предложения команды по вызволению Спирита из западни в местечке "Troy".
