Причем практически все хорошо ложатся на тик в 2 недели от сего дня. Вроде бы.

Hubble to Proceed with Full Search for New Horizons Targets

July 1, 2014 02:00 PM (EDT)
News Release Number: STScI-2014-35

Спойлер

NASA's Hubble Space Telescope has been given the go-ahead to conduct an intensive search for a suitable outer solar system object that the New Horizons (NH) spacecraft could visit after the probe streaks though the Pluto system in July 2015.

Hubble observations will begin in July and are expected to conclude in August.

Assuming a suitable target is found at the completion of the survey and some follow-up observations are made later in the year, if NASA approves, the New Horizon's trajectory can be modified in the fall of 2015 to rendezvous with the target Kuiper Belt object (KBO) three to four years later.

The Kuiper Belt is a debris field of icy bodies left over from the solar system's formation 4.6 billion years ago. Though the belt was hypothesized in a 1951 science paper by astronomer Gerard Kuiper, no Kuiper Belt objects were found until the early 1990s. So far over 1,000 KBOs have been cataloged, though it's hypothesized many more KBOs exist.

The approval for additional observing time for the needle-in-a-haystack search is based on the analysis of a set of pilot observations obtained with the Space Telescope Science Institute (STScI) director's discretionary time on Hubble. After a swift and intensive data analysis of approximately 200 Hubble images, the NH team met the pilot program criterion of finding a minimum of two KBOs.

"Once again the Hubble Space Telescope has demonstrated the ability to explore the universe in new and unexpected ways," said John Grunsfeld, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington, D.C. "Hubble science is at its best when it works in concert with other NASA missions and ground-based observatories."

It will be many weeks before the team can establish whether either of these pilot-program KBOs is a suitable target for New Horizons to visit, but their discovery provides sufficient evidence that a wider search to be executed with Hubble will find an optimum object.

"I am delighted that our initial investment of Hubble time paid off. We are looking forward see if the team can find a suitable KBO that New Horizons might be able to visit after its fly-by of Pluto," said STScI director Matt Mountain.

In early June, Hubble's Time Allocation Committee awarded time for a full search with the requirement that its implementation be contingent on the success of the pilot survey.

From June 16 to June 26, the New Horizons team used Hubble to perform a preliminary search to see how abundant small Kuiper Belt objects are in the vast outer rim of our solar system.

Hubble looked at 20 areas of the sky to identify any small KBOs. The team analyzed each of pilot program images with software tools that sped up the KBO identification process. Hubble's sharp vision and unique sensitivity allowed very faint KBOs to be identified as they drifted against the far more distant background stars, objects that had previously eluded searches by some of the world's largest ground-based telescopes.

Ну, поскольку тут они округляют до сотых, видимо ещё чуть больше 3 а.е.
Ждём официального объявления (шильдика с отметкой)  :)

Первая. Удачи, Горизонты!

Очередная веха от che wi пройдена: остался ровно год до пролета Плутона.

Известно что-нибудь о примерной дате пролета одного из объектов пояса Койпера? Вроде бы как два возможных кандидата найдено. Или их орбиты еще не уточнены?

New Horizons Marks a 'Year Out' with a Successful Course Correction
http://pluto.jhuapl.edu/news_center/news/20140715.php

July 15, 2014

New Horizons performed a slight course correction yesterday, a short maneuver designed to correct the spacecraft's arrival time – a year from now – at the precisely intended aim point at Pluto.

The maneuver – during which New Horizons fired its thrusters for just under 88 seconds – sped the craft up by about 2.4 miles per hour and keeps it on track for a flight past Pluto that culminates next July 14. "If we hadn't performed this maneuver, we would have arrived at Pluto about 36 minutes later than we wanted to," said Mark Holdridge, New Horizons encounter mission manager at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Md. "Making the adjustment now means we won't have to perform a bigger maneuver – and use more of the spacecraft's fuel – down the road."

While the maneuver itself happened onboard the spacecraft at 10:45 p.m. EDT on July 14, data indicating that the burn went as planned arrived in the New Horizons Mission Operations Center at APL at 4:30 a.m. EDT on July 15 – after traveling nearly four hours from the spacecraft, which is nearly 2.7 billion miles from home, through NASA's Deep Space Network.

"It was a great burn, performed flawlessly" said Alan Stern, New Horizons principal investigator from Southwest Research Institute, Boulder, Colo. "You could say that New Horizons just lit a little candle for its one year out anniversary."

It was the spacecraft's sixth course correction maneuver since launch in January 2006, and the first since 2010. New Horizons mission design team lead Yanping Guo, from APL, noted that the maneuver marked the first change in the Pluto encounter trajectory since 2008, now that the team has better information on the predicted locations of Pluto and its largest moon, Charon. "That information is critical to making sure the sequence of science observations, which will be programmed into New Horizons' computers, goes exactly as planned," Guo said.

Holdridge added that New Horizons will take images of the Pluto system as it approaches Pluto, beginning early next year, and navigation and flight dynamics experts will them to design additional maneuvers to further refine the spacecraft's course.

Во вселенной Mass Effect спутник Плутона Харон является заледеневшим ретранслятором массы — устройством неизвестного происхождения для перемещения космических кораблей между различными точками Галактики. Через этот ретранслятор состоялся контакт людей с турианцами, приведший к вооружённому конфликту.

А механизм активации у него случайно не автоматический, при приближении к нему космического аппарата? А то через год глядишь турианцы к нам пожалуют, а мы как бы еще не доросли до технологического уровня mass effect, раскидают нас как котят)

Не, у них же не принято было во всякие неизвестные ретрансляторы заходить. А то мало ли кто оттуда вылезет  

А если по теме, то как там с новостями насчет Хаббла? Подтверждаются кандидаты? Новые есть?
