Bad Astronomy Be prepared for the faraway meeting of mankind: Tonight for MU69 tonight!



This late evening (or tomorrow early in the morning, if you want), the New Horizons spacecraft will carry out the most remote aircraft of the astronomical object made by humanity. 05:33 PM Starting from 1 January, the New Year 2014 will last from MU69 to 3,500 kilometers, all of which will become ice and mountain. If successful, the probe returns the first close-up of the in situ Kuiper belt object, the data is stunning 6.6 billion Km From the ground.

Yes, it's a big deal.

You can recall the New Trends as a spaceship in July 2015 with Pluto, and you can recall many of the smaller glaciers, including the magnificent images that reflect on the external solar system.

But the solar system does not end with Neptune and Pluto. It has basically a coated form space with millions of rock and ice objects. For historical reasons, this is called the "Kuyer" belt. For decades, the form of the first Kuiper belt (or KBO) was not found until the 1990s … and now we know thousands of people. Some people (including me) believe that Pluto is the largest of these currently known objects.

Pluto's flight in 2015 is still intended for a second destination for the New Horizons in the Cape Bridge. The story behind this is really great – Alex Parker, a member of the team, wrote a wonderful blog for NASA Great theme on Twitter – but in the year 2014 Hubble CMC was discovered for a brief description of the long story that approached the trajectory of spacecraft, leaving the available fuel. 2014 MU69 has been handed over, but you will be called the Ultima Thule, after which the New Horizons team has given him an informal nickname after holding a public race.

We do not know much about MU69. It is so distant and so small that it is hardly visible to earth telescopes, and even the New Orion will not notice it until August 2018. The orbit is mild elliptical and retains more than 6 billion km of the Sun. About a billion miles from plutonium. Some clever observations MU69 are dual lobel objects or two objects, very closely interconnected (as a two-sided object) or 67P / Churyumov-Gerasimenko comet. The two components are approximately 20 kilometers (and maybe less). We know it is red, because most of these substances (the sun's UV rays destroy carbon molecules that turn into the most complex molecules called thermoin, and they are red).

About this. But in a few days we know exhibition More.

I invite you to read the pardon of this friend, Emily Lacadval, who wrote for the planet's society. His article is always clear, interesting, and everything needs to be understood.

There are several points I would like to make.

One that MU69 is so small and bad, and just recently opened, we do not know its position precisely. Planning a plan is good enough, but the new horizons come closer as the uncertainty goes bigger. Remember that MU69 is only about 20-40 km away … and new horizons are at a relative velocity 14 km per second Over 50 thousand miles per hour. Therefore, MU69 does not have a pixel or more than three.

Engineers will play it safe and will be able to disassemble the spacecraft several times earlier, which will make MU69 reliable, and then somewhere nearer to see some details. But the meeting is very fast, the spacecraft makes a pre-programmed set of meeting, which is always exploring the MU69. Photographs will not be sent back until it's over … they will receive radio waves traveling at light speeds (because of light) within six hours to return to Earth. Scientists then look at scientists, but do not let them public (as it is usually needed to simplify the scan of the spacecraft for raw material), so that one or several days before seeing the actual pictures.

What do we see? This is a good question. In time, there was an interesting news about the brightness of MU69 (what astronomy is called) light curve) is very smooth, it is amazing. If it is extended (or two orbital items), it can be expected that it will be too bright and dark in the turn. If the page is open, you will be sure that the brightness changes. However, nothing looks like this. Is this unusual? Or we can see that we look directly at one of his pillars, so we can not see new features. This last bit looks unlikely because we see it have two major components and it's hard to know how to get them, but look down the pole. That is why it is odd.

Are there any smaller months for the main body orbit? Is there a ring there? Is there a dust cloud around it? Is the surface level smooth or rough, ceiling or flat, crater or smooth? All of these are important questions that tell us much about this remote object, and hope that all of them will respond to new horizons.

In the next few days, they will respond.

By the way, next week I'll be at Star Trek: Cruise Line Internet III. Maybe I can not write about any videos I get. So check out the original page of SYFY for the views of other authors, Follow Emily on Twitter, at the same time publishes his Twitter account. You can also follow The New Horizons Mission On Twitter and home: Please Alex Parker go on ahead.

Let's see what's going on there.
