In ne way, it is the“greatest”drne ever. In anther, thugh, it is the ppsite f what a drne shuld be. Drnes shuld be very lazy. They dn’t have t wrk. Only their sisters shuld be busy pllinating (给……传授花粉) and prducing hney. Hwever, fr this drne, pllinatin is the very reasn fr its existence(存在).
The drne, in fact, is an inventin f Eijir Miyak. Miyak is a scientist frm Japan. Many peple, including Miyak, have been wrried abut the future f the fd industry. Pllinating insects, especially bees, are falling in number. As a result, sme plants can’t get pllinated and there will be fewer plants fr us t eat. Scientists have been wrking hard t increase the number f bees. Unfrtunately, they have had little success. Perhaps, Miyak thinks, it is time t build sme rbt bees instead.

At the mment, Miyak’s rbt bee still needs help frm human peratrs. That’s because it can’t “see” where its targets (目标) are. In the next step, Miyak will install visual recgnitin (视觉识别) sftware n his bee. After that the rbt bee will be able t “see” by itself.

Junk is everywhere,even in space.Space junk travels at eight kilmeters a secnd,accrding t an article in The Guardian.Catching it may be a little difficult.
Luckily,scientists at the Swiss Space Center have a new cleaning plan.They are abut t send a “cleaner satellite” int space.It will clean up space junk.Named “Clean Space One”,the Swiss satellite finds its target and mves clse t it.When it reaches its target,it will catch the junk with a gripping claw (抓手).This is nt ging t be an easy task because bth the satellite and the junk are traveling s fast.
Once Clean Space One has caught the junk,all it has t d t get rid f it is t fly back t the Earth.This is because the junk will burn up when traveling thrugh the atmsphere(大气层).The satellite,t, will burn up at the same time.
S far,NASA has fund 16,000 pieces f junk that are larger than 10cm in diameter and mre than 500,000 pieces measuring between 1cm and 10cm.Yu can imagine hw many even smaller nes there are in space.
Space junk is dangerus fr spacecraft and the Internatinal Space Statin.Even a very small piece f junk culd seriusly destry a satellite r spacecraft if they cllide (碰撞).The Internatinal Space Statin has t regularly change its rbit(轨道) t avid space junk.
