Star man's Tesla completes orbit around the sun

斯達(dá)曼的特斯拉完成繞太陽(yáng)公轉(zhuǎn)

The Starman sitting behind the wheel of Elon Musk's original cherry red Tesla Roadster is most certainly living up to his name.

坐在埃隆•馬斯克最初的櫻桃紅色特斯拉跑車方向盤(pán)后面的斯塔曼,無(wú)疑是名副其實(shí)的明星。

Though you won't be able to see Starman in the sky the way you can pick out the International Space Station, you can follow along on the Where Is Roadster site, which also offers interesting trivia. For instance, as of this writing, the vehicle has traveled the equivalent of driving all of the world’s roads 33.8 times and the car is getting roughly 6,000 miles per gallon. (The site isn't affiliated with SpaceX or Tesla or even Elon Musk. As the creator of the site says, "I'm just this guy, you know?")

雖然你無(wú)法像分辨國(guó)際空間站那樣在天空中看到斯達(dá)曼,但你可以在“Where Is Roadster”網(wǎng)站上找到它,該網(wǎng)站也提供了一些有趣的瑣事。例如,在撰寫(xiě)本文時(shí),這輛車的行駛里程相當(dāng)于行駛了全球所有道路的33.8倍,每加侖汽油行駛約6000英里。(該網(wǎng)站與SpaceX、特斯拉甚至埃隆馬斯克都沒(méi)有關(guān)聯(lián)。正如該網(wǎng)站的創(chuàng)始人所說(shuō):“我就是這樣一個(gè)人,你知道嗎?”)

The moment follows the first milestone, when Starman passed beyond the orbit of Mars — a distance of more than 180 million miles from Earth.

這是第一個(gè)里程碑式的時(shí)刻,斯達(dá)曼超越了火星軌道——距離地球超過(guò)1.8億英里。

Before the famous launch, Musk revealed that instead of the concrete dummy payloads traditionally used by aerospace companies during test flights, he would instead be donating his 2008-model Roadster complete with a mannequin clad in a SpaceX pressure spacesuit.

在那次著名的發(fā)射之前,馬斯克透露,他將捐贈(zèng)他的2008年款跑車,其中包括一個(gè)穿著SpaceX壓力航天服的人體模型,而不是航天公司在試飛時(shí)通常使用的混凝土假人載荷。

"Payload will be my midnight cherry Tesla Roadster playing 'Space Oddity'," Musk tweeted. "Destination is Mars orbit. Will be in deep space for a billion years or so if it doesn't blow up on ascent."

馬斯克在推特上寫(xiě)道:“有效載荷將是我的午夜櫻桃特斯拉跑車,它將播放《Space Oddity》。”“目的地是火星軌道。如果它在上升過(guò)程中不爆炸,它將在深太空中存在10億年左右。”

After a successful launch aboard the Falcon Heavy, the Roadster spent six glorious hours in what's ironically called a "parking orbit" around Earth. Cameras secured to the upper stage of the Falcon Heavy transmitted live video that is still something to behold.

在獵鷹重型火箭成功發(fā)射后,這輛跑車在環(huán)繞地球的“停車軌道”上度過(guò)了6個(gè)小時(shí)的光輝時(shí)光。固定在獵鷹重型火箭上層的攝像頭傳輸?shù)膶?shí)時(shí)視頻,仍然值得一看。

Others are quick to point out that there may not be much left of Starman to destroy when the end finally comes. Much of the vehicle's organic materials — plastics, fabrics, tires, even its cherry-red paint — will, according to Indiana University chemist William Carroll, likely be destroyed relatively quickly by radiation and impacts from small meteoroids.

其他人則很快指出,當(dāng)《星際迷航》的結(jié)局最終到來(lái)時(shí),可能已經(jīng)沒(méi)有多少剩余的東西可以摧毀了。據(jù)印第安納大學(xué)的化學(xué)家威廉·卡羅爾說(shuō),這輛車的大部分有機(jī)材料——塑料、織物、輪胎,甚至櫻桃紅色的油漆——很可能很快就會(huì)被輻射和小流星體的撞擊摧毀。

Inorganic materials such as the vehicle's aluminum frame and glass windows will last longer, making the car recognizable by some estimates for at least a million years.

無(wú)機(jī)材料,如汽車的鋁框架和玻璃窗,將持續(xù)更長(zhǎng)的時(shí)間,使一些人估計(jì),汽車可識(shí)別至少100萬(wàn)年。

So "Don't Panic!" — as the console screen on the Roadster reads — Starman in some form or another will likely be around cruising our galaxy long after we're all stardust. But man, what a ride!

“別慌!”——正如跑車上的控制臺(tái)屏幕顯示的那樣——在我們都是星塵之后很長(zhǎng)一段時(shí)間里,以某種形式存在的斯達(dá)曼很可能還會(huì)在銀河系中巡航。但是,伙計(jì),這是一次多么美妙的旅行啊!
