Opportunity news
9 месяцев Opportunity ходил вокруг кратера, думал с какой стороны лучше, и в итоге вернулся на то место, с которого начал.
Принято решение спускаться именно там.

Наконец. Авось какие окаменелости найдет.

Огромный пылевой шторм надвигается, не факт что Opportunity выживет...

A giant dust storm brewing on Mars could permanently jeopardize the future of the Mars Exploration Rovers mission, officials told SPACE.com today, as the storm now covers nearly the planet's entire southern hemisphere.
The new and potentially bleak outlook is a stark shift from the prognosis earlier this week.
The dusty squall has reduced direct sunlight to Mars' surface by nearly 99 percent, an unprecedented threat for the solar-powered robotic explorers. If the storm keeps up and thickens with even more dust, officials fear the rovers' batteries may empty and silence the robotic explorers forever.
"This is a scary storm," said Mark Lemmon, a planetary scientist at Texas A&M University and member of the rover team. "If it gets any worse, we'll enter into some uncharted territory. There's been a lot of discussion about what we're going to do if (the rovers) don't have enough power to run during the day."
...
"The reality of the situation is that we're limited as to what we can do from the ground by cutting power use," Callas said. "If it continues to worsen and stay that way, it's a survivability issue for Opportunity. If Mars wants to kill the rovers, it can."

Before the dust storms began blocking sunlight last month, Opportunity's solar panels had been producing about 700 watt hours of electricity per day, enough to light a 100-watt bulb for seven hours. When dust in the air reduced the panels' daily output to less than 400 watt hours, the rover team suspended driving and most observations, including use of the robotic arm, cameras and spectrometers to study the site where Opportunity is located.
On Tuesday, July 17, the output from Opportunity's solar panels dropped to 148 watt hours, the lowest point for either rover. On Wednesday, Opportunity's solar-panel output dropped even lower, to 128 watt hours.
"We are taking more aggressive action with both rovers than we needed before," said John Callas, project manager for the twin rovers at NASA’s Jet Propulsion Laboratory, Pasadena, Calif.
By Opportunity's 1,236th Martian day, which ended Tuesday, driving and all science observations had already been suspended. The rover still used more energy than its solar panels could generate on that day, drawing down its battery. "The only thing left to cut were some of the communication sessions," Callas said.
To minimize further the amount of energy Opportunity is using, mission controllers sent commands on Wednesday, July 18, instructing the rover to refrain from communicating with Earth on Thursday and Friday. This is the first time either of the rovers has been told to skip communications for a day or more in order to conserve energy. Engineers calculate that skipping communications sessions should lower daily energy use to less than 130 watt hours.
Ничего себе, было 700 watt hours, стало 128.

Угу. Афанареть. Интересно, как механика при таких бурях еще живет
А она неземная. Космического уровня надежности. Как и электроника
Также как и физика с химией?
Смотря что вы под этим понимаете.
Физические и химически законы, скорее всего, на Марсе все-таки те же
Химический состав атмосферы и грунта, их физические свойства - неземные, ясен пень
Любите людей.

Скажите, это Вас в школе отучили задавать вопросы, отсылая на MSN Search?
Нет. В школе научили прочесть главу из учебника, прежде чем начинать задавать вопросы по этой самой главе.

От модератора:
int21h, здесь, слава Богу, не школа, и вы Иопу не учитель.
Иоп, вы тоже прекращайте перебранку. Хамский тон не приветствуется на форуме.

Here is a great example why sending humans to Mars is plain stupid (at least in the near future).
You can temporarely shut down a robot, but try doing that with humans.
