Мда...
Вот так и рождаются нездоровые сенсации и мифы.
Завтра очередной гость вообще скажет, что Старый открыл воду на Марсе.

Все не так.
Судя по этой и многим другим картинкам, правы ВСЕ, кто считает, что на на Марсе имеется мощная криолитосфера aka типа наша вечная мерзлота, только намного толще (порядка 1,4-2 км) и содержание воды в ней может быть по-больше.

Вообще Старый быссовестно эксплуатирует фотографии с явными следами таяния вечномерзлотного грунта, выдавая это за таяние пятикилометрового слоя практически чистого льда под тоненькой присыпкой. Он каждый раз радостно кричит "Вот она - вода! Значит там ледник глубиной 5 км!", хотя там всего-навсего растаял подземный лед...

Точность до 100 метров в словах Белла поражает своей обоснованностью!

[Bell]

ГЫ!  :lol:
Очепятка, ессно "1,5-2 км".

Подкинуть ссылку на классическую работу по теме криолитосферы Марса?

Даже не ожидал, что так быстро найду.

[Дмитрий Виницкий]

Спаибо. К сожалению, это известная работа...

[Bell]

Ха!
Так в том и дело! И изложенные в ней идеи давно известны и даже общепризнаны в кругах специалистов, насколько я знаю.

[Дмитрий Виницкий]

Разве это может останавливать таких новаторов как Старый!
ЗЫ. Я в 1983 году писал статью по геоморфологии Марса. Надо поискать в Известиях СКНЦ

О, ДА!
Ежели нам пофигу здравый смысл и мнение спецов, то нас ничто не остановит! :lol:
Да здравствует буйство воображения! Свободный полет фантазии, бессмысленной и беспощадной!

Даже так?!
Интересно было бы почитать.

[Дмитрий Виницкий]

Я бы тоже посмеялся. Под рукой была геоморфологическая карта полушарий Марса, изданная в ГЕОХИ, кажется в 1980 году тиражом аж 200 экз. Ноя на основании пары викинговских снимков описывал участки с выраженным криогенезом
Тьфу, ты ни хрена не помню. Но вот то что хвалили преподы, не забылось :oops:

Марсис глючит
But on Friday flight control technicians found that one of the 13 segments of this boom had not locked properly into position

Deployment of second MARSIS boom delayed
 

The deployment of the second antenna boom of the Mars Express Sub-Surface Sounding Radar Altimeter (MARSIS) science experiment has been delayed pending investigation of an anomaly found during deployment of the first antenna boom.

The anomaly was discovered on 7 May towards the end of the first deployment operations. Deployment of the first boom started on Wednesday 4 May. The problem with the boom was confirmed by flight control engineers working at ESA's European Space Operations Centre (ESOC) in Darmstadt, Germany, on 7 May, after which further activity was stopped pending a full assessment of the situation.

The operations to deploy the remaining two booms could be resumed in a few weeks, after a thorough analysis and investigation of the Boom 1 deployment characteristics.

The second of two identical radar booms has been deployed [/size]on Europe's Mars Express spacecraft - but it is not yet clear if the operation was successful. If it was, the antenna could begin scouting for underground water on Mars within a week.

Mission managers in Darmstadt, Germany, deployed the 20-metre-long boom on 14 June at 1130 GMT. After a series of manoeuvres designed to warm the boom evenly in sunshine, the spacecraft reoriented itself towards Earth about two hours later and began beaming data to mission control.

"It's always good to see your spacecraft back under control," says Fred Jansen, the spacecraft's mission manager. "But we know from the first boom's deployment that this does not tell the full story, so we are not declaring the operation successful yet."

That first boom in the MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding) experiment popped out of its storage box on 4 May. But a few days later, engineers discovered one of its outer hinges had failed to lock into place during deployment, leaving a slight kink in the antenna.

Mission managers suspected the coldness of space played a role in the problem, so on 10 May they exposed the crooked boom to the Sun for a few minutes. The warming trick worked - the boom straightened and locked in place - but an analysis showed the spacecraft itself could become unstable if a kink were to occur on an inner segment of the second boom. So mission planners postponed the deployment of that boom - which is crucial for the instrument to function - to study the issue.

Hinge heater
In deploying boom 2, mission managers set Mars Express rotating very slowly with the stored boom facing generally towards the Sun. Then, they deployed the boom and kept rotating the spacecraft so that, in half an hour, the boom rotated through 180 degrees.

"So if you assume a hinge is at an angle somewhere, the Sun would illuminate all the hinges and heat them up," Jansen told New Scientist.

Managers will study data from the spacecraft's gyroscopes, which measure its rotation, to see whether the boom deployed straight. They hope to finish their analysis of the deployment on Thursday.

If the procedure was a success, mission officials will deploy the third and final boom on 17 June. This is a 7-metre-long pole that will help determine whether the reflected radio waves are coming from underground, but it is not critical to the mission. If all goes to plan, the experiment is set to record its first data on 21 June, as part of its initial commissioning phase.

MARSIS was originally scheduled to be deployed in April 2004 but was delayed for a year over concerns that the springy booms could have hit and damage the spacecraft during deployment. But further Earth-based tests allayed those fears.

Scientists hope MARSIS will discover whether the water that once carved canyons on the Red Planet's surface has seeped into underground reserves. Such reserves might harbour life or be used to supply future crewed missions to Mars
