福衛五號發射全紀錄
串流直播日期：2017年8月25日
台灣第一顆MIT衛星【福衛五號】，在台灣時間8月25號凌晨2點50分升空順利發射升空，並順利完成通聯，就在上午9點32分，福衛五號首度通過台灣上空，太空中心也與福衛五號取得聯繫。預計在兩周後，就能傳回第一張照片，未來一年可拍下21萬1647幅影像，提供地面各項觀測。
經過六年的時間研發，終於等到發射這一天。【福衛五號】外觀呈現八角柱，重量450公斤，發射載具SPACE-X獵鷹九號。

2017-08-25 03:56聯合報 記者林良齊╱即時報導
福衛五號在凌晨2時51分順利升空，約十分鐘後在720公里高的軌道運作，並將在凌晨4時13分與國研院太空中心斯瓦巴海外站首次通聯，早上約9點與台灣地面站首次通聯。
此次福衛五號搭乘Space X的獵鷹九號火箭升空，預計在150秒、88公里第一節火箭脫離，158秒、100公里時第二節火箭點火，166秒、114公里鼻錐罩脫離，560秒時、725公里時二節火箭熄火，676秒時、723公里處衛星與火箭脫離，預計在720公里高、太陽同步軌道運行。
福五升空後將延續福衛二號遙測任務，所拍攝的影像可應用於政府施政、防災勘災、國土安全、環境監控、科技外交、學術研究及國際人道救援等用途；也可利用上頭搭載的先進電離層探測儀偵測太空天氣或地震前兆電離層變化。
Terrifying ‘dark universe’ discovered within our universe and it spells DOOM for humanity.
A MYSTERIOUS ‘dark universe’ which exists alongside our own visible universe has been mapped by scientists. And the findings spell ultimate doom for humankind.

A team from the international Dark Energy Survey (DES) collaboration believes their findings support the theory that about just four percent of the present composition of the universe is ordinary matter.
The rest, the team says, is made up of substances that remain ‘dark’, largely un-knowable and in many cases simply theoretical.
The research backed scientific hypothesis that 26 percent of the universe is made up of mysterious cold dark matter, and the bulk – a whopping 70 percent – is “in the form of an elusive dark energy.”
Our knowledge of both is extremely limited but Dark Energy is believed to be responsible for the accelerating expansion of the universe.
And the continued expansion seem to provide concrete evidence that the universe will ultimately suffer a ‘heat death’ where energy is exhausted and what is left behind is very cold and very dead.
This image of the NGC 1398 galaxy was taken with the Dark Energy Camera.
Cold dark matter is theorised to be a non-luminous material which exists is comprised of weakly interacting particles.
When it is made of high-energy randomly moving particles, created soon after the Big Bang, it is described as hot dark matter.
Meanwhile, dark energy is a theoretical form of energy thought to permeate space, accelerating the expansion of the universe at an increased rate.
David Bacon of the University of Portsmouth said: “Dark matter is invisible to us, but we can see its effects – its gravity is bending the light from distant galaxies, so they look distorted to us. We can work back from measuring the distortions to mapping the cause. It’s so exciting to see this truly vast map of the dark Universe at last.”
