Next-Generation Space Capsule To Endure First Flight Test

On Dec. 4, NASA will launch the Orion capsule on its first space flight aboard the Delta IV Heavy rocket. The vehicle, which is expected to one day carry astronauts to an asteroid and Mars, will perform its first mission unmanned. It is being loaded up with radiation, heat and acceleration sensors, among numerous other instruments, to perform a fact-finding test flight for future exploration.

The four-and-a-half-hour trip will make two orbits around Earth and also test safety systems that will be critical to keeping astronauts alive and comfortable. Orion will go as far as 3,600 miles above Earth to pass through the Van Allen Belt, an area of high radiation levels, to test shielding designed to protect humans from harmful charged particles as they venture deeper into space.

地球の周りをキモい軌道でグルグル回っていた不思議な物体「J002E3」の動きが一発で分かるGIFアニメ | ロケットニュース24

今から11年前の2002年、ひとりのアマチュア天文学者が宇宙に漂う不思議な物体を発見した。その物体は地球周回軌道上に存在しており、「な、なんと! 月以外に地球の周りを回る物体があったなんて……!」と研究者たちはビックリ仰天したという。

この未知なる物体は「J002E3」と名付けられ、しばらくは隕石や小惑星だと思われていたが、やがて意外な事実が発覚する。「こ、これは……人工的な物体だ……ッ!!」と。今回は、そんな J002E3 の動きが一発で分かるGIFアニメをご紹介したい。
・月よりも地球に接近していた

金星の方向から地球に向かって突っ込んできた J002E3。月の軌道もぶっちぎり、月よりも地球に近い位置をグルリとカーブ。その後も、楕円の軌道で月と地球の間を自由気ままに周回し、やがて再び金星方向に飛び去っている。
・正体は40年以上も前に行方不明になっていたモノだった

一体全体、J002E3 とは何だったのか。調査の結果、その正体は1969年に打ち上げられたアポロ12号で使われた「サターンVロケット」の第3段ステージ「S-IVB」であることが判明した。そう、宇宙での役目を終えてから行方不明になっていたロケットの一部が、40年の時を経て地球の近くに帰ってきていたのである!

ちなみに「J002E3」こと、自由気ままに宇宙を放浪するフーテンの「S-IVB」は、2032年頃に再び地球周回軌道上に帰ってくる可能性があるらしい。そのときは「おかえりなさい!」と心のなかで言ってあげよう。

This is how the solar system is actually moving as it traverses the galaxy.

Wait

Yeah it’s not circular as you’ve been taught. It does revolve around the sun, but like every other star, the sun travels, and pulls us too. Fih-boe-nah-chi

This image was obtained with the wide-field view of the Mosaic camera on the WIYN 0.9-meter telescope on Kitt Peak, Arizona. The Pleiades are an open cluster easily visible to the naked eye. The cluster is dominated by several hot, luminous and massive stars. The blue nebulosity surrounding the brightest stars are due to blue light from the stars scattering off of dust grains in the interstellar gas between us and the stars. The cluster is also known as the ‘Seven Sisters’. And in Japan it is called Subaru. The image was generated with observations in the B (blue), V (green), and I (red) filters. In this image, North is right, East is up.

Saturn’s shadows

It may seem odd to think of planets casting shadows out in the inky blackness of space, but it is a common phenomenon. Earth’s shadow obscures the Moon during a lunar eclipse, and Jupiter’s moons cast small shadows onto their parent planet.  
One of the best places in our Solar System to spot intriguing and beautiful celestial shadows is at Saturn. On 1 July, the international Cassini mission celebrates 10 years of exploring Saturn, its rings and its moons, an endeavour that has produced invaluable science but also stunning images like this.
Drifting along in the foreground, small and serene, is Saturn’s icy moon Mimas. The blue backdrop may at first appear to be the gas giant’s famous and impressive set of rings, with pale and dark regions separated by long inky black slashes, but it is actually the northern hemisphere of Saturn itself. The dark lines slicing across the frame are shadows cast by the rings onto the planet.
Although we may not associate the colour blue with Saturn, when Cassini arrived at the planet the northernmost regions displayed the delicate blue palette shown in this image. As this region of Saturn is generally quite free of cloud, scattering by molecules in the atmosphere causes sunlight to take a longer path through the atmosphere. The light is scattered predominantly at shorter – bluer – wavelengths. This is similar to why the sky on Earth appears blue to our eyes.
Seasonal changes over the years since this photo was taken have turned the blue into Saturn’s more familiar golden hue. The reverse is occurring in the south, which is slowly becoming bluer.

Planets of Our Solar System

Our solar system officially has eight planets and one star: the Sun. The discovery of an object larger than Pluto in 2005 rekindled the debate over whether such objects, belonging to the Kuiper Belt – a collection of icy bodies located beyond Neptune – should be called planets. Pluto and other large members of the Kuiper Belt are now considered “dwarf planets.”
