It is a small step fr a plant, and a giant leap fr plant kind. A spruting (發(fā)芽) cttn seed n China’s Chang’e-4 lunar lander is the first plant ever t grw in anther wrld, indicating a new era fr life in space.
Seeds, including cttn, arabidpsis (擬南芥), ilseed rape (油菜) and ptat were carried t the Mn as a part f bilgical experiment, alng with fruit fly eggs and sme yeasts (酵母).
Pictures sent back by the prbe shw the cttn seeds spruting n January 7, 2019, a few days after Chang’e-4 landed n the far side f the Mn.
The rganisms (生物) are in a sealed can, prtected frm the extreme temperatures and radiatin n the surface. “Understanding hw t grw plants in space will help lay the fundatin fr human settlement n the Mn,” a scientist leading the experiment tld the Suth China Mrning Pst.
The six rganisms are intended t frm a mini-ecsystem, with the plants making xygen and fd t sustain the fruit flies. Yeasts culd prcess the flies’ waste and dead plants t prvide anther fd surce.
In a future human settlement, ptates culd prvide fd, rapeseed culd be a surce f il and cttn culd be used fr clthing. A study in 2014 reprted that plants culd sprut and grw in lunar sil fr 50 days withut any additinal nutrients (營養(yǎng)物). Over lnger perids, human waste culd help supprt plants’ nutritinal needs.
These lunar green shts aren’t the first plants in space. Astrnauts n the Internatinal Space Statin have grwn crps including peas, radishes and cucumbers. They gt their first bites f space-grwn rmaine lettuce in 2015.
The China Natinal Space Administratin eventually hpes t put humans n the Mn. “We are studying the prgram f sending astrnauts t the Mn, but it’s still in very early stages,” a deputy directr tld the Suth China Mrning Pst. “We haven’t gt the apprval yet.”

Fr thse f us wh grew up watching Star Trek, explring space has been abut discvering strange new wrlds. And there are plenty f wrlds t explre in time, but we still need majr technlgical advancements t reach planets that are light years away.
What we are ding in space tday is prviding unbelievable benefits right nw, right here n Earth. Frm space, we can mnitr, manage and care fr ur planet. Satellite-based sensrs shw us the shrt- and lng-term effects f human activity n ur envirnment. Many cmpanies are using their interest in space t help slve prblems here, frm using hyperspectral imaging(高光譜成像), which enable us t map vegetatin(植被) and rain frests, t micrsatellites that prvide glbal cnnectivity fr the netwrk f things.
My cmpany, OneWeb, is fcusing n what I believe is ne f the wrld’s mst imprtant issues: the need fr equal access t the Internet. The Internet has becme ur ecnmic lifebld. And yet, nearly half f the wrld’s ppulatin desn’t have Internet access. Space is playing a key rle in bridging this digital divide. OneWeb is launching 1,980 satellites t help bring Internet access t peple everywhere, and ur first prductin satellites are already flying in space and have shwn very high dwnlad speeds.
Fiber and cable Internet access technlgies already cver mst financially viable(可行的) majr cities. Similarly, these regins will als be the first t be served with 5G. Pr cmmunities are the last t get cnnected, and withut cnnectivity, thse cmmunities have n chance t lift themselves frm pverty. OneWeb’s satellites will reach every cmmunity in the wrld and enable equal access t the Internet fr the wrld’s less develped places.
Fifty years frm the day when man first walked n the mn, we are still nly appraching the pssible. There will be tens f thusands f new satellites, space statins and factries in the cming years t bring advancements in cmmunicatins, scientific research, mnitring the earth, explring space and mre. This is exciting, but we must take actin carefully.
