    Two years ago, aerospace manufacturer SpaceX shocked the world by landing its reusable booster (助推器) engine — the biggest and most costly part of the rocket used to power spacecraft into low orbit — on an autonomous drone ship in the Atlantic Ocean. Now, California-based startup Rocket Lab, has come up with an even more courageous idea: using parachutes and helicopters to capture the returning booster, or first stage as it is often called, in the air!

    Rocket Lab's decision to avoid the propulsive or vertical (垂直的) landing used by SpaceX comes from its business model to keep its Electron rockets small and cost-effective. Standing just 57 feet tall, they are designed to deliver smaller payloads (有效载重) of about 500 pounds for only $5 million a launch. In contrast, the SpaceX Falcon 9 rocket measuring 229 feet tall can lift up to 50,000 pounds, costs about $62 million a mission. "We're not in the business of building medium-sized launch vehicles but small ones for customers to get on orbit frequently." said Rocket Lab CEO Peter Beck.

    Similar to other rockets, the Electron divides into two once it reaches outer space. While the top part, carrying the load, continues on to its final destination, the booster engine falls back to Earth The company intends to fix a ballute — a parachute-like braking device — to quickly slow down the booster's supersonic speed (超声速) upon its return into the atmosphere. Once it slows down to a reasonable pace, a helicopter will grab the rocket from midair and put it onto an awaiting ship to transport to the company's headquarters. Beck said: "The grand goal here is that if we can capture the vehicle in wonderful condition, in theory, we should be able to put it back on the pad, charge the batteries up, and go again."

    The idea, still in the concept stage, will become one step closer to becoming a reality during Electron's next launch, scheduled for sometime in 3 years, "Engineers will carefully monitor the first stage as it returns, testing its ability to guide its landing with the best way to slow down its speed," said Beck.

    Telepathy (心灵感应) is the ability to communicate without the use of the five senses. It's an instinct (本能) which can be woken up in times of emergency or need. When we feel that something is happening or about to happen by instinct,we're using resources within the unconscious (潜意识的) mind. When the resources of two persons' unconscious minds link together into the same frequency (频率),we call it telepathy.

    We can either send or receive telepathy. If you know who is calling before you answer the ringing phone,you are probably a good receiver. If you think of a person and he/she calls you,you are most likely to be better at sending.

    You can easily put your ability to the test. Thinking of somebody and wish him or her to contact you. Be patient. The other person may not be a good receiver,but they should contact you much earlier than would normally be expected. Or whenever the phone rings,try ‘feeling' who is contacting you. Don't guess,but try to feel it with your mind. However,if neither of these works for you,that doesn't mean that you have no ability of telepathy. As mentioned earlier,telepathy is most likely to turn up in case of emergency.

    Telepathy dreams often contain telepathic messages. Two people may both dream of the other and find that their dreams have a clear connection. These people are probably linking to each other's unconscious mind.

    Telepathy & relationship. The more people spend time together,the more likely they are to be able to link up to the other's mind,especially when separated. There are two reasons for this. One is that they understand the other's mind through time spent together;the other is that there is usually a strong desire to communicate. A mother will often sense that her child is in danger. This is due to the child's eagerly wanting his or her mother,knowing that this is the person who would always want to be there for them,and the mother's deep desire to protect her child from harm.

    I was getting ready to go to bed when the phone rang. This could not be good. My mind raced through the list of family members who might need help, but the voice was hardly familiar.

    "Lindy, this is Lesley." I don't know Lesley well. We did occasionally speak with each other, but to say we were friends was not appropriate. I asked what she needed. Perhaps something really awful caused her to reach someone she barely knew. Instead, she asked me, "Do you have room for a turkey? In your freezer?" We had lots of room in our freezer, and in fact, too much. "Sure," I responded, "did your freezer break down?" "Not exactly," Lesley replied, but I will explain when I arrive."

    Minutes later came a huge freezer truck. Lesley stepped down and explained the lease (租约) of the grocery store her husband serviced had run out and that they had to empty all the freezers that very night. Thinking it was a shame to throw away all this good food, they decided to drop off food to anyone she could think of. Noticing our freezer was pretty empty, Lesley asked to fill it up. Our home was their last stop and anything left would have to be put in our freezer. An hour later, everything finished, I asked her, "When will you come back for all this?" Lesley laughed, "We don't want it back. It is yours! Thanks for helping us out!" Then they waved goodbye and drove away.

    "For helping them out?" We opened our freezer door. Inside were all expensive foods we never bought but often longed to try. We were struggling to buy groceries, yet it was not something we shared with anyone. However, our needs were met in an unexpected way, by that call, "Do you have room for a turkey?"

    We interviewed two people, one who went from the country to the city and one who did the opposite.

    Janet Lincoln is a salesgirl who moved to St. Louis five years ago. Here's what Janet told us:

    "Five years ago I used to live in a small town called Lemon Falls. I grew up and went to high school there. After I graduated I worked in a supermarket. Lemon Falls had a population of about 800 people, and I knew every single one of them. They all knew everything about me, too. You couldn't do anything without everyone in town knowing about it. The first chance I got I moved to St. Louis and I love it. I don't know as many people now as I used to, but that's OK.I have a few good friends, and I see them when I want to. I kind of like being anonymous. I'd never go back to Lemon Falls."

    Troy Henson had the opposite experience. He and his wife, Darla, and their two children moved from St. Louis to Bloomfield three years ago. Here's what Troy told us:

    "The best thing we ever did was get out of St. Louis. Don't get me wrong; St. Louis is as good a place as any other city, I suppose—if you like cities, that is. We don't. Both Darla and I grew up in St. Louis. We met at college and got married. Then the kids came along and life got difficult. We didn't know any of our neighbors. We both had good jobs, but it always seemed like there was never enough money. That all changed when we moved to Bloomfield. I don't make as much money as I used to, but then we don't have as many expenses as we did. We know our neighbors. Life is good. We'd never leave Bloomfield."

    There was a gardener who looked after his garden with great care. To water his flowers, he used two buckets(水桶).One was a shiny and new bucket. The other was a very old and dilapidated one, which had seen many years of service, but was now past its best.

    Every morning, the gardener would fill up the two buckets. Then he would carry them along the path, one on each side, to the flowerbeds. The new bucket was very proud of itself. It could carry a full bucket of water without a single drop spilled. The old bucket felt very ashamed(惭愧的)because of its holes: before it reached the flowerbeds, much water had leaked(渗漏)along the path.

    Sometimes the new bucket would say, "See how capable I am! How good it is that the gardener has me water the flowers every day! I don't know why he still uses you. What a waste of space you are!"

    And all that the old bucket could say was, "I know I am not very useful, but I can only do my best. I am happy that the gardener still finds a little bit of use in me, at least."

    One day, the gardener heard that kind of conversation. After watering the flowers as usual, he said, "You both have done your work very well. Now I am going to carry you back, and I want you to look carefully along the path."

    Then the two buckets did so. All along the path, they noticed, on the side where the new bucket was carried, there was just bare earth; on the other side where the old bucket was carried, there was a joyous row of wild flowers, leading all the way to the garden.
