Lightbulb NASA's "Kepler" Mission

NASA's first mission capable of finding Earth-size and smaller planets around other stars.

The Kepler spacecraft is undergoing careful preparations ahead of launch, which is scheduled to take place March 5 from Cape Canaveral Air Force Station. Under NASA's Launch Services Program, a Delta II rocket will boost the observatory into space where the Kepler will survey about 100,000 stars in the Milky Way galaxy for Earth-sized planets.

Launch night has finally arrived for NASA's Kepler spacecraft. The planet hunter is set to lift off at 10:49:57 p.m. EST atop a United Launch Alliance Delta II rocket. Final preparations are well under way at Launch Pad 17-B at Cape Canaveral Air Force Station in Florida. Tonight's forecast is very promising, with a 95 percent chance of good weather.

Some quick facts about the Kepler mission, scheduled to launch March 6, 2009:

-- Kepler is the world's first mission with the ability to find true Earth analogs -- planets that orbit stars like our sun in the "habitable zone." The habitable zone is the region around a star where the temperature is just right for water -- an essential ingredient for life as we know it -- to pool on a planet's surface.

-- By the end of Kepler's three-and-one-half-year mission, it will give us a good idea of how common or rare other Earths are in our Milky Way galaxy. This will be an important step in answering the age-old question: Are we alone?

-- Kepler detects planets by looking for periodic dips in the brightness of stars. Some planets pass in front of their stars as seen from our point of view on Earth; when they do, they cause their stars to dim slightly, an event Kepler can see.

-- Kepler has the largest camera ever launched into space, a 95-megapixel array of charge-coupled devices, or CCDs, like those in everyday digital cameras.

-- Kepler's telescope is so powerful that, from its view up in space, it could detect one person in a small town turning off a porch light at night.

'کپلر' برای یافتن سیارات قابل سکونت به فضا رفت

ناسا، آژانس فضایی آمریکا تلسکوپی را به فضا پرتاب کرده است تا در نقاط دوردست کهکشان راه شیری به دنبال سیاره هایی که به زمین شباهت دارند بگردد.

این تلسکوپ که کپلر نامگذاری شده، جستجوی خود را به آن قسمت از فضای اطراف ستارگان محدود خواهد کرد که احتمال وجود آب مایع در سیاره های واقع در آن فضا بالا است (موسوم به مناطق گرم، یا مناطق قابل سکونت).

دانشمندان معتقدند وجود آب مایع بر روی سطح یک کره نشاندهنده امکان بالقوه حیاتی مشابه کره زمین بر روی آن است.

این تلسکوپ به بررسی روشنایی بیش از 100 هزار ستاره در منظومه های لایرا (Lyra) و سیگنوس (Cygnus) خواهد پرداخت و به جستجوی ستاره هایی خواهد پرداخت که شدت نور آنها بطور متوالی و به واسطه عبور سیارات در حال چرخش به دور آنها از میان ستاره مورد نظر و تلسکوپ کم و زیاد می شود.

این تلسکوپ که پنج متر طول دارد به مدت سه سال و نیم به دور خورشید خواهد گشت تا برنامه خود را به اتمام برساند.

تسکوپ کپلر در ساعت 3:49 دقیقه صبح به وقت گرینویچ در روز هفتم مارس به فضا پرتاب شد.

کپلر از بزرگترین دوربینی برخوردار است که تا کنون به فضا پرتاب شده و این اولین بار است که ماموریتی با هدف یافتن کرات خاکی درحال
چرخش به دور ستاره هایی همچون خورشید انجام می شود.

اعتقاد بر آن است که از میان 300 سیاره فراخورشیدی که تاکنون کشف شده اند تعداد بسیار کمی از آنها همانند کره زمین، خاکی هستند ولی
هیچکدام جرمی مانند زمین ندارند. اکثر این سیاره ها یا همانند سیاره مشتری توده های عظیم گاز هستند یا همانند نپتون یک جرم یخی عظیم به شمار می روند.

با این حال دانشمندان معتقدند دلیل کم بودن شمار چنین سیاراتی، بیشتر محدودیت های فنی بشر در کشف آنها است و نه فقدان سیاراتی با جرم مشابه زمین در کهکشان راه شیری.
