  تلقت وكالة الفضاء الأمريكية "ناسا" إشارة، من مسبارها "نيوهورايزونز" الذي نجح في التحليق بالقرب من أبعد نقطة في مجموعتنا الشمسية.

 

ومر المسبار بسرعة كبيرة، بالقرب من كويكب "أولتيما تولي"، الذي يتكون من كرة عملاقة من الثلج، عرضها نحو 30 كيلومترا.

 

وحلق المسبار الفضائي على بعد 6.5 مليار كيلو متر من الأرض، وهي أبعد مسافة يتم الوصول إليها حتى الآن، لاستكشاف جسم في النظام الشمسي.

 

وسيمد المسبار وكالة ناسا بفيض من المعلومات والصور والبيانات العلمية على مدار الأشهر المقبلة.

 

والتقط هوائي تابع للوكالة في اسبانيا إشارة مرور المسبار نيوهورايزونز

 

وهلل العاملون في مختبر جونز هوبكنز للفيزياء التطبيقية بولاية ماريلاند عندما وصلت الإشارات الأولى للمسبار.

 

وقالت أليس بومان مديرة عمليات المهمة "لدينا مركبة فضاء بحالة جيدة للغاية" موضحة أن المركبة ستبعث بالمزيد من الصور والبيانات من الصخرة الفضائية في الأيام القادمة.

 

ويعطي هذا الاتصال المبدئي المراقبين فكرة جيدة، عن أداء المسبار نيوهورايزونز، لدى تحليقه على بعد 3500 كيلومتر من سطح تولي.

ويقع كويكب تولي في المنطقة المسماة حزام كويبر، على بعد 1.5 مليار كيلو متر من الكوكب القزم بلوتو، الذي زاره المسبار نيو هورايزونز عام 2015.

 

وتشير التقديرات إلى أن هناك آلاف الأجسام في حزام كويبر مثل كويكب تولي، ومن المؤكد أن حالتهم المتجمدة تحمل أدلة، على ظروف تكون النظام الشمسي، قبل نحو 4.6 مليار عام.

 

ويقول كبير الباحثين في مهمة نيوهورايزونز، آلان ستيرن "الليلة الماضية، أجرت مركبة الفضاء الأمريكية نيو هورايزونز أبعد عملية استكشاف في تاريخ البشرية، وأنجزت ذلك بشكل مذهل".

 

ورة لصخرة (تولي)، أرسلت الليلة الماضية ولم تحمل تفاصيل أكثر تذكر عن صور سابقة، تزيد الغموض بشأن ما إذا كانت (تولي) صخرة واحدة تشبه حبة فول سوداني غير متماثلة أم أنها فعليا صخرتان تدوران حول بعضهما و"صورتهما مشوشة بسبب قربهما من بعضهما".

 

وصُمم المسبار نيوهورايزونز، لكي يقترب من سطح كويكب أولتيما، لمسافة 3500 كيلو متر، ومراقبة دورانه، 

 

 

مسبار يقترب من صخرة ضمن مهمة تاريخية

 

 

المسبار نيو هورايزونز (رويترز)
 يعتقد العلماء أن مسبارا استكشافيا أطلقته إدارة الطيران والفضاء الأميركية (ناسا) وصل إلى آخر أطراف المجموعة الشمسية في ساعة مبكرة من صباح أمس (الثلثاء)، وأنه يحلق على مقربة من صخرة فضائية طولها 20 ميلا وتبعد بلايين الأميال عن الأرض في إطار مهمة لجمع معلومات عن نشأة المجموعة الشمسية.
 
 
ومن المتوقع أن يصل المسبار (نيو هورايزونز) إلى ما يعرف بالمنطقة الثالثة في أعماق حزام كويبر الساعة 12:33 بتوقيت شرق الولايات المتحدة. ولن يحصل العلماء على تأكيد لوصوله بنجاح إلا بعد أن يرسل المسبار بيانات عن مكانه عبر شبكة الفضاء السحيق التابعة لناسا الساعة 10:28 بتوقيت شرق الولايات المتحدة، أي بعد ذلك بنحو عشر ساعات.
 
وبمجرد دخول المسبار الطبقة الخارجية للحزام التي تحتوي على أجسام متجمدة ومخلفات لنشأة المجموعة الشمسية، فإنه سيلقي نظرة أولى عن قرب على ألتيما ثولي وهي كتلة كبيرة في شكل حبة الفول السوداني.
 
 
وتقول ناسا إن العلماء لم يكونوا قد اكتشفوا ألتيما ثولي عند إطلاق المسبار مما يجعل مهمته فريدة من نوعها. وفي عام 2014، رصد علماء الفلك ألتيما ثولي باستخدام التليسكوب الفضائي هابل واختاروه ليكون ضمن مهمة (نيو هورايزونز) الطويلة التي بدأت عام 2015.
 
وقال جون سبنسر، وهو أحد العلماء في مشروع (نيو هورايزونز)، للصحافيين في مختبر جونز هوبكينز للفيزياء التطبيقية بولاية ماريلاند أول من أمس: «كل شيء محتمل في هذه المنطقة المجهولة بشدة».
 
وانطلق (نيو هورايزونز) في كانون الثاني (يناير) 2006 لقطع أربعة بلايين ميل صوب الأطراف المتجمدة للمجموعة الشمسية لدراسة الكوكب القزم بلوتو وأقماره الخمسة.
 
وخلال اقترابه من بلوتو عام 2015، اكتشف المسبار أن بلوتو أكبر قليلا مما هو معتقد. وفي آذار (مارس)، اكتشف وجود كثبان غنية بغاز الميثان على سطح بلوتو. وقطع المسبار بليون ميل بعد بلوتو باتجاه حزام كويبر ويسعى الآن للحصول على معلومات عن نشأة المجموعة الشمسية وكواكبها.

WHATS NEXT FOR THE MISSON? 

Some black and white images may be available later today.

Highly anticipated close-ups wont be ready until Wednesday or Thursday, in color, it is hoped.

Overnight tonight, the science team will be analyzing the first high resolution images. 

Color images will come down this week, Alan Stern said. 

Over time, the resolution will improve.

The highest resolution images wont arrive until February. 

Engineers locked onto the signal, and data began to be downloaded from a tracking system in Madrid. 

Everything looks great, we are looking forward to getting down the science data.

We did it again. 

Im really liking this 2019 thing so far, said Mission Controller Alan Stern, who said he had got a good nights sleep after celebrating the flyby last night.

New Horizons did spectacularly.

Stern revealed the last picture the craft took before the flyby, and promised better images tomorrow. 

Overnight tonight, the science team will be analyzing the first high resolution images, and well show you those tomorrow.

Its 35x50km, and its an irregular shape. 

It could be bi-lobate, with asymetric lobes, or it could be these are two things in orbit - and tomorrow we will known which is the case.

Everything we are seeing now happened about six hours ago, said Mark Holdridge, the Encounter Mission Manager. 

Theres a lot of anxious people staring at screens in Mission control.

Now it is entering the peripheral layer of the belt, containing icy bodies and leftover fragments from the solar systems creation, the probe will get its first close-up glance of Ultima Thule, a cool mass shaped like a giant peanut, using seven on-board instruments.

The first image of Ultima Thules shape was taken during the spacecrafts approach but clearer pictures are not expected for some time as it can take several hours for radio signals to reach Earth from that far away.

Flight controllers had said everything looked good for New Horizons flyby of the tiny, icy

object nicknamed Ultima Thule at 12:33 a.m. on Tuesday.

 

 

The mysterious, ancient tar

get is 4 billion miles (6.4 billion kilometers) from Earth and is in the Kuiper Belt.

Scientists wanted New Horizons observing Ultima Thule during the encounter, not phoning home.

 
 
Nasa tweeted after the flyby that confirmation of the signal from the spacecraft will be made public at 9.45am

So they had to wait until late morning before learning whether the spacecraft survived.

With New Horizons on autopilot, Mission Control was empty at Johns Hopkins Universitys Applied Physics Laboratory in Laurel, Maryland. 

Instead, hundreds of team members and their guests gathered nearby on campus for back-to-back countdowns.

The crowd ushered in 2019 at midnight, then cheered, blew party horns and jubilantly waved small U.S. flags again 33 minutes later, the appointed time for New Horizons closest approach to Ultima Thule. 

A few black-and-white pictures of Ultima Thule might be available following Tuesdays official confirmation, but the highly anticipated close-ups wont be ready until Wednesday or Thursday, in color, it is hoped.

We set a record. Never before has a spacecraft explored anything so far away, said the projects lead scientist who led the countdown to the close encounter, Alan Stern of Southwest Research Institute. Think of it. Were a billion miles farther than Pluto.

Stern called it an auspicious beginning to 2019, which will mark the 50th anniversary of Neil Armstrong and Buzz Aldrins footsteps on the moon in July 1969.

Ultima Thule is 17,000 times as far away as the giant leap of Apollos lunar missions, Stern noted in an opinion piece in The New York Times. 

New Horizons, which is the size of a baby grand piano and part of an $800 million mission, was expected to hurtle to within 2,200 miles (3,500 kilometers) of Ultima Thule, considerably closer than the Pluto encounter of 2015.

Its seven science instruments were to continue collecting data for four hours after the flyby. 

New Horizons has spent more than a decade hurtling through the solar system since it launched on Jan 19, 2006 and passed Pluto in 2015. Its messages take to reach us, despite them traveling at the speed of light

Then the spacecraft was to turn briefly toward Earth to transmit word of its success. It takes over six hours for radio signals to reach Earth from that far away.

Scientists believe there should be no rings or moons around Ultima Thule that might endanger New Horizons. 

Traveling at 31,500 mph (50,700 kph), the spacecraft could easily be knocked out by a rice-size particle. 

Its a tougher encounter than at Pluto because of the distance and the considerable unknowns, and because the spacecraft is older now.

I cant promise you success. We are straining the capabilities of this spacecraft, Stern said at a news conference Monday. By tomorrow, well know how we did. So stay tuned. There are no second chances for New Horizons.

The risk added to the excitement.

Queen guitarist Brian May, who also happens to be an astrophysicist, joined the team at Johns Hopkins for a midnight premiere of the rock n roll song he wrote for the big event.

We will never forget this moment, said May who led the New Years countdown. This is completely unknown territory.

Despite the government shutdown, several NASA scientists and other employees showed up at Johns Hopkins as private citizens, unwilling to miss history in the making.

Ultima Thule was unknown until 2014, eight years after New Horizons departed Earth. It was discovered by the Hubble Space Telescope and added to New Horizons itinerary.

Deep inside the so-called Kuiper Belt, a frigid expanse beyond Neptune that is also known as the Twilight Zone, Ultima Thule is believed to date back 4.5 billion years to the formation of our solar system. As such, it is probably the best time capsule weve ever had for understanding the birth of our solar system and the planets in it, Stern said.

In classic and medieval literature, Thule was the most distant, northernmost place beyond the known world.

NASA¿s New Horizons spacecraft spotted its next flyby target earlier this year from more than 100 million miles away. In the image, Ultima is enveloped in countless stars, appearing as just a tiny speck amidst the bright spots. The yellow box shows its predicted location

Scientists suspect Ultima Thule is a single object no more than 20 miles (32 kilometers) long. 

WHATS NEXT FOR NEW HORIZONS? 

While NASA has said goodbye to a few of its veteran craft recently, including Cassini and Kepler, New Horizons work may not be ending any time soon.

The spacecraft is very healthy, it has fueling power to go on for 15, 20 years, Prinicipal Investigator Alan Stern told Dailymail.com.

And, wed like to do another flyby. We dont leave the Kuiper Belt until 2027, 2028.

So after we get all the data, thats what were going to do. Work on our next exploration phase.

Were happy about this, its an amazing piece of American workmanship this little spacecraft thats doing so well.  

It is thought to be potato-shaped and dark-colored  with a touch of red, possibly from being zapped by cosmic rays for eons.

The exact shape and composition wont be known until Ultima Thule starts sending back data in a process expected to last almost two years.

Who knows what we might find? ... Anythings possible out there in this very unknown region, said John Spencer, a deputy project scientist from Southwest Research Institute. Well find out soon enough.

New Horizons Principal Investigator Alan Stern told Dailymail.com: Its going to take us 20 months to get all the data back, because data transmission speed is slow from that distance. 

Well be sending back data about Ultima Thule for all of 2019 and most of 2020, until August or September, Stern says.

The first picture will get to Earth on the 1st, though this will only reveal Ultimas shape, Stern says.

It will just be a few pixels, like a smudge, Stern told Dailymail.com.

Finer details are expected to come in the days to follow, with its surface features coming to light on the 3rd and 4th.

WHAT IS ULTIMA THULE? 

The Kuiper Belt object was discovered by the Hubble Space Telescope in 2014. Officially known as 2014 MU69, it got the nickname Ultima Thule in an online vote.

In classic and medieval literature, Thule was the most distant, northernmost place beyond the known world.

Ultima Thule might not be a single object. Scientists say its possible its two or many objects. An artists impression is pictured

When New Horizons first glimpsed the rocky iceball in August it was just a dot. Good close-up pictures should be available the day after the flyby.

New Horizons will make its closest approach in the wee hours of Jan. 1 - 12:33 a.m. EST.

Scientists speculate Ultima Thule could be two objects closely orbiting one another. If a solo act, its likely 20 miles (32 kilometers) long at most.

Envision a baked potato. Cucumber, whatever. Pick your favorite vegetable, said astronomer Carey Lisse of Johns Hopkins.

It could even be two bodies connected by a neck. If twins, each could be 9 miles to 12 miles (15 kilometers to 20 kilometers) in diameter.

Scientists will map Ultima Thule every possible way. They anticipate impact craters, possibly also pits and sinkholes, but its surface also could prove to be smooth.
