NASA is developing the capabilities needed to send humans to an asteroid（小行星）by 2025 and then Mars in the 2030s—goals outlined in NASA’s official documents 2014．
Mars is a rich destination tor scientific discovery and robotic and human exploration as we expand our presence into the solar system．Future exploration could uncover evidence of life，answering one of the fundamental mysteries：Does life exist beyond Earth?
While robotic explorers have studied Mars for more than 40 years，NASA’s path for the human exploration of Mars begins in low-Earth orbit aboard the International Space Station．Astronauts on the orbiting laboratory are helping us prove many of the technologies and communications systems needed for human missions（任务）to deep space，including Mars．The space station also advances our understanding of how the body changes in space and how to protect astronaut health．
Our next step is deep space，where NASA will send a robotic mission to catch and redirect an asteroid to orbit the moon．Astronauts aboard the Orion spacecraft will explore the asteroid in the 2020s，returning to Earth with samples．This experience in human spaceflight beyond low-Earth orbit will help NASA test new systems，which we’ll need to send cargo（货物）as part of human missions to Mars．Beginning in FY 2018，NASA’s powerfull Space Launch System（SLS）rocket will enable these "proving ground" missions to test new technologies．Human missions to Mars will rely on Orion and an evolved version of SLS that will be the most powerful launch vehicle ever flown。
A lot of robotic spacecraft and rovers（探测器）already are on and around Mars，greatly increasing our knowledge about the Red Planet and paving the way of future human explorers．The Mars Science Laboratory Curiosity rover measured radiation on the way to Mars and is sending back radiation data from the surface．This data will help us plan how to protect the astronauts who will explore Mars．Future missions like the Mars 2020 rover，seeking signs of past life，also will demonstrate new technologies that could help astronauts survive on Mars．
Engineers and scientists around the country are working hard to develop the technologies astronauts will use to one day live and work on Mars，and safely return home from the next giant leap for humanity．NASA also is a leader in a Global Exploration Roadmap，working with international partners and the U．S．commercial space industry with human missions to the surface of Mars as the driving goal．

Self-driving vehicles will rely on cameras, sensors and artificial intelligence（AI）to recognize and respond to road and traffic conditions, but sensing is the most effective for objects and movement in the neighborhood of the vehicle. Not everything important in a car’s environment will be caught by the vehicle’s camera. Another vehicle approaching at high speed on a collision （碰撞）track might not be visible until it’s too late. This is why vehicle-to-vehicle communication is undergoing rapid development. Our research shows that cars will need to be able to chat and cooperate on the road, although the technical challenges are considerable.
Applications for vehicle-to-vehicle communication range from vehicles driving together in a row, to safety messages about nearby emergency vehicles. Vehicles could alert each other to avoid collisions or share notices about passers-by and bicycles.
From as far as several hundred metres away, vehicles could exchange messages with one another or receive information from roadside units（RSUs）about nearby incidents or dangerous road conditions through 4G network A high level of A1 seems required for such vehicles, not only to self-drive from A to B, but also to react intelligently to messages received. Vehicles will need to plan, reason, strategize and adapt in the light of information received in real time and to carry out cooperative behaviours. For example, a group of autonomous vehicles might avoid a route together because of potential risks, or a vehicle could decide to drop someone off earlier due to messages received, a foreseen crowding ahead.
Further applications of vehicle-to-vehicle communication are still being researched, including how to perform cooperative behaviour.

“An Uber self-driving car hit and killed a woman crossing the street in Arizona，U．S．，”police said on Monday，marking the first death caused by an autonomous vehicle and a potential blow to the technology expected to transform transportation．
The ride services company said it was delaying North American tests of its self-driving vehicles，which are currently going on in Arizona，Pittsburgh and Toronto．
So-called robot cars，when fully developed by companies including Uber，are expected to thoroughly cut down on motor vehicle deaths and create billion-dollar businesses．But Monday’s accident highlighted (凸显)the possible challenges ahead for the promising technology as the cars face real-world situations involving real people．
“This catastrophic accident highlights why we need to be exceptionally cautious when testing and applying autonomous vehicle technologies to public roads，”said Edward Markey， a member of the transportation committee，in a statement．
“Elaine Herzberg，49，was walking her bicycle outside the crosswalk on a four-lane road in the Phoenix suburb of Tempe at about 10 p．m． MST Sunday when she was struck by the Uber vehicle traveling at about 65 kilometers per hour，”police said．The car was in autonomous mode with an operator behind the wheel．U．S． federal safety officials were sending teams to investigate the crash．Canada’s transportation ministry in Ontario，where Uber conducts testing，also said it was reviewing the accident．
“Uber and Waymo on Friday urged Congress to pass a law to speed the introduction of self-driving cars into the united states．However，some congressional(国会的)representatives have blocked the legislation over safety concerns，and Monday’s death could hamper passage of the bill，”congressional assistants said Monday．

A team of scientists from University of Freiburg in Germany are developing a shoe with a sensor to automatically tie its laces(鞋带)that could be taken off when users click their heels together．
It’s been 26 years since we saw them magically tightening Marty McFly’s Nike boots in the film Back to The Future．
Now，self-tying shoelaces could actually become a reality this year，proving right one of the film’s fantastical predictions for what 2015 would be like．
Engineers have designed a shoe that can automatically lace up，adjusting itself to the shape of your foot．
Simply slip the controller on and pressure sensors will tell the ‘smart shoe’ when your foot is in position，triggering(触发)a tiny motor in the heel that pulls the laces tight.
When you want to take off the shoes，you click your heels together twice and the motor will release a spring(弹簧)in the shoe’s tongue，which loosens the laces enough for you to slip them off．
And the invention doesn’t even need to be plugged in to charge or have its battery replaced because it runs on power generated by the swing of your foot as you walk.
Engineer K1evis Ylli，of the Institute for Micromachining and Information Technology in southern Gemany，said the shoes could help a variety of different people.
“One focus is that it could be used in shoes for elderly people who have mobility problems，”he said．“But it could also work for children，or as a lifestyle product．”．
The design，which is still in a prototype(雏形)stage，cleverly gets the energy of the foot’s swing when opposing magnets in each shoe move past each other. It then uses that power to charge a battery．An hour of walking is enough to tighten the laces once，and it requires no energy to undo the shoes because that relies on the spring alone.
1.Which of the following can be the best title of the text?
A．A fantastical prediction
B．A great invention in Germany
C．A shoe with self-tying laces
D．A popular lifestyle product
2.What can we learn about the shoes?
A．They can automatically take off．
B．They can adjust themselves to your foot．
C．They need to be charged once．
D．They have been in design for 26 years．
3.From the last paragraph we can know ____________．
A．the shoes have been put into use
B．the shoes need power to take off
C．the shoes promise to be popular
D．how the shoes work to produce energy
