本周二下午3:45,由埃隆•馬斯克企下公司SpaceX打造的獵鷹重型(Falcon Heavy)火箭在佛羅里達(dá)州肯尼迪航天中心成功起飛,有意思的是此火箭還搭載了一臺(tái)馬斯克的個(gè)人特斯拉(Tesla)跑車,車上放置了一個(gè)穿著太空服的假人。火箭完美將測(cè)試載荷送入軌道,馬斯克又創(chuàng)造了歷史性的一刻。
早在去年,馬斯克就宣布了他計(jì)劃將特斯拉汽車放入重型獵鷹火箭,當(dāng)時(shí)就有人問(wèn)到他為什么要扔掉價(jià)值10萬(wàn)美元的車,而馬斯克是這樣回復(fù)的,“我喜歡這樣一個(gè)想法,讓汽車在無(wú)限的太空中漂流,也許數(shù)百萬(wàn)年后的將來(lái)會(huì)被外星人所發(fā)現(xiàn)”。
As early as last year, musk announced his plan to tesla motors in the falcon heavy rockets, was asked why did he throw away $100000 worth of cars, and musk is replies, "I like this one idea, let the car drift in the infinite space, perhaps millions of years in the future will be found by aliens".
據(jù)了解,獵鷹重型主要由SpaceX公司的三架主力獵鷹9火箭推動(dòng)器并列在一起,其中兩個(gè)火箭推動(dòng)器脫離后安全落在著陸點(diǎn)附近,而第三個(gè)推動(dòng)器似乎出了點(diǎn)問(wèn)題,無(wú)法識(shí)別出海上回收無(wú)人船位置,最終以每小時(shí)300英里的速度撞向海洋,距無(wú)人機(jī)船只有300英尺。
獵鷹重型是怎樣煉成的?
馬斯克表示,獵鷹重型能夠?qū)?4萬(wàn)磅的重物提升到低地球軌道,這是今天任何其它火箭所不能達(dá)到的。由于三架火箭推動(dòng)器可以回收再利用,所以重型火箭不會(huì)超過(guò)公司現(xiàn)在其它火箭的成本。根據(jù)SpaceX公司列出的價(jià)格表,一臺(tái)重型獵鷹火箭價(jià)格是9000萬(wàn)美元,獵鷹9號(hào)推動(dòng)器價(jià)格是6200萬(wàn)美元。SpaceX以較低的價(jià)格和可重復(fù)使用的推動(dòng)器打亂了全球火箭發(fā)射的業(yè)務(wù)市場(chǎng)。
A heavy falcon rocket costs $90 million and falcon 9 drives $62 million. SpaceX has disrupted the global market for rocket launches with lower prices and reusable boosters.
火箭的成功發(fā)射標(biāo)志著SpaceX公司邁進(jìn)了巨大的一步,馬斯克已經(jīng)成功用突破性技術(shù)撼動(dòng)了火箭工業(yè)。事實(shí)證明了,SpaceX公司能夠讓獵鷹9號(hào)一級(jí)火箭推動(dòng)器順利返回地球,火箭回收的歷史最早可以追溯到2012年,至今公司已經(jīng)使用這項(xiàng)技術(shù)完成了40個(gè)任務(wù)。
The launch marks a huge step forward for SpaceX, which has successfully shaken up the rocket industry with a breakthrough technology. , in the fact that the ferry companies can let the falcon 9 stage driver to return to earth, a rocket recycling history can be traced back to 2012, the earliest company has finished 40 tasks using the technology.
這項(xiàng)技術(shù)使得SpaceX公司可以將使用過(guò)的推動(dòng)器恢復(fù)并重新利用。事實(shí)上,首飛的獵鷹重型運(yùn)載火箭使用了兩個(gè)前獵鷹9推動(dòng)器,另外再加了一個(gè)新的推動(dòng)器。重復(fù)使用硬件使得SpaceX進(jìn)一步降低了成本。
The technology allows SpaceX to recover and reuse its used propellers. In fact, the first falcon heavy launch vehicle USES two former falcon 9 drivers, plus a new driver. The repeated use of hardware has further reduced the cost of SpaceX.
在此火箭回收項(xiàng)目之前,每次任務(wù)后公司都不得不放棄掉火箭。其實(shí),重型獵鷹不是歷史上最強(qiáng)大的火箭,此前美國(guó)航空航天局(NASA)的土星五號(hào)(Saturn V)運(yùn)載火箭獲得史上最強(qiáng)的榮譽(yù),此火箭用于阿波羅登月,并在70年代退役。
Before the rocket recovery program, the company had to give up the rocket every time. In fact, the falcon heavy is not in the history of the most powerful rocket, NASA (NASA) before the Saturn V () Saturn V rocket glory in the history of the strongest, the rockets for the Apollo moon landing, and retired in the 70 s.
