上周四，波音（Boeing）首席執(zhí)行官丹尼斯·米倫伯格宣布公司致力于成為載人登陸火星偉大計劃的先驅(qū)?！叭祟愖罱K將登上火星，我堅信，登陸火星的第一個人乘坐的是波音火箭，”米倫伯格今晨對CNBC主持人吉姆·克萊姆說道。隨后，特斯拉（Tesla）和SpaceX公司首席執(zhí)行官埃隆·馬斯克發(fā)布了一條推特，下了戰(zhàn)書。

馬斯克在看到“財富科技（Fortune Tech）”賬號發(fā)布的一條可鏈接到《財富》關(guān)于米倫伯格大膽預(yù)言的新聞報道的推特后，言簡意賅地回應(yīng)道，“去干吧”。

這并非是米倫伯格首次作出這種預(yù)言。去年的一次技術(shù)大會上，他表達了相似的觀點。然而，馬斯克更是雄心勃勃，不僅放話要登陸火星，還要開拓這一星球。對于公眾而言，一提起火星探索，腦海里就會浮現(xiàn)這位名聞四方的億萬富翁的大名。十月，馬斯克制定了關(guān)于登陸火星的SpaceX 戰(zhàn)略計劃，設(shè)定了要將大批人口安置在這一星球的目標，這是他致力于將人類轉(zhuǎn)化為“多星球物種”的愿景的一部分。

馬斯克認為旗下的SpaceX 最快2022年可以將宇宙飛船送上火星。而米倫伯格周四宣布波音的下一代火箭的測試計劃將于2019年展開。

馬斯克在推特上十分活躍，以熱衷在特斯拉客戶和評論家之間插話而出名。去年，這位億萬富翁甚至與《財富》在推特上起了點小口角（包括屏蔽《財富》的推特主賬號），原因是《財富》報道特斯拉出現(xiàn)奪命車禍以及馬斯克隨后出售特斯拉股票套現(xiàn)一事。（財富中文網(wǎng)）

The Tesla and SpaceX CEO posted a challenge on Twitter after Boeing CEO Dennis Muilenburg said on Thursday that his aerospace giant would transport the first humans to Mars. “Eventually we’re going to go Mars and I firmly believe the first person that sets foot on Mars will get there on a Boeing rocket,” Muilenburg told CNBC’s Jim Cramer this morning.

In response to a tweet from the “Fortune Tech” Twitter account linking to Fortune’s news article about Muilenburg’s bold bet, Musk simply wrote, “Do it.”

Muilenburg has made the same proclamation in the past, including last year at a tech conference. However, Musk’s own very public ambitions to not only reach Mars, but to colonize the Red Planet, seem to have linked the celebrity billionaire’s name with the idea of Mars exploration in the public imagination. In October, Musk outlined the SpaceX strategy for reaching Mars and even his goal of settling large groups of people on the planet as part of his vision of making humans into a “multiplanetary species.”

Musk believes that SpaceX could begin landing spaceships on Mars as soon as 2022, while Muilenburg said on Thursday’s that Boeing’s own next generation rockets would be tested starting in 2019.

Musk is an active Twitter user who is known to jump into the Twitter conversations among Tesla customers and critics. Last year, the billionaire even engaged in a brief Twitter spat with Fortune (including blocking Fortune‘s primary Twitter account) over its reporting in the wake of a Tesla driver’s fatal crash and Musk’s post-crash sale of Tesla shares in a public offering.
