Back in 1969, it was the Apollo 11 crew who flew to the moon in a spaceship. When U.S. astronauts Neil Armstrong and Edwin “Buzz” Aldrin stepped foot on the moon, they were the first. Meanwhile, their fellow astronaut Michael Coilins circled the moon in their spaceship, named Columbia.

    When Armstrong and Aldrin were done with their walk，they returned to the command module, and back to Earth. That part of the spaceship is on view at the Smithsonian's Air and Space Museum in Washington, D.C. But, if you cannot get to Washington，soon you will be able to see Columbia on your computer or your smartphone.

    Digital scientists are scanning the inside of the spaceship. They are creating an online model, in three dimensions, or“3 D”. By looking at these photographs, you will be able to see outer space，the way the astronauts did. It will be like sitting in their seats.

    Want your very own Columbia spaceship? You will be able to print a 3D copy of Columbia. Experts say anyone can make a life-sized model. But they expect most people to make smaller models of the 320×400 cm(11'X 13')command module.

    Scientists are using special 3D technology to scan the inside. They use cameras on long arms to take the photographs. The thousands of photographs taken will be combined with 50 laser scans.

    What would it be like to sit inside Columbia and take a look around? All the images will be loaded into software that allows you to look around the module on a computer screen. The user will be able to see the Columbia both inside and out. The Smithsonian says that the 3D technology gives the user ways to see things they cannot see at the museum. And it will give information that even the museum curators(馆长)have not seen before.

    “With the Command Module, no one has been inside since it came into the collection,” says Adam Metallo. Smithsonian 3D imaging specialist. “Now the information we capture can give anyone in the world a view of what it looks like inside this incredible piece of history.”

    I'd always dreamed of exploring Africa, ever since I read my first Tarzan (《人猿泰山》)comic as a child. Finally, in 2004, to celebrate my 60th birthday, I went to Tanzania to experience a safari （东非游猎）and climb Mount Kilimanjaro, the highest mountain in Africa. Seated next to me on the flight was Tanzania's minister of water and wildlife development. We talked for thousands of miles, and he arranged me to visit a school. When I toured the school, I was shocked. The leaky (漏的) roofs turned the dirt floors into mud during the rainy season, and the walls couldn't keep out the heat, cold or bugs (小昆虫). The school was in need of all material goods, but the kids possessed great human spirit.

    It broke my heart that these children had to struggle to survive, so I asked the headmaster what it would cost to feed them. As little as 20 cents per child per day, he told me. Immediately I got home, I founded Kids of Kilimanjaro. Since then we've grown to provide hot lunches for nearly 13,000 schoolchildren every day. The free lunch program has eased a major problem the youngsters face.

    I know a good education could really make a difference in these children's lives. My parents always stressed the importance of education. I paid my own way through college in Tokyo by teaching English to students and businesspeople. After attending university I moved to San Francisco, when I was 25 years old. In 1978 I realized my American dream when I founded my own company. My success all started with a good education.

    It's amazing that something as simple as a nutritious lunch can change and enrich so many lives. Giving young people a better, healthier life can inspire them to go all the way through college and lead a movement that transforms their country.

    I was disheartened recently when I turned on the news to hear a story about a family who is petitioning (请愿) the Hampton School Board to receive out-of-district compensation to place their daughter in an out-of-district school due to racial bullying. I was disheartened because I know that even if this family wins their petition, the root of the problem will still continue.

    While there are many contributing factors to the rapid increase of the bullying, I believe that the root of this problem lies within the restrictions of schools, or rather the teachers and administrators who allow bullying to happen while feeding the line "We have a no-tolerance policy" to students and parents.

    This family can move their daughter to a new school where she will feel safe to learn and grow, but they will leave behind the problem of the educators at this school who let the racial bullying happen.

    My son went to a private school in Concord. He was bullied on the play yard. The administration gave us the "No tolerance" line, but did nothing to stop the bullying or change the climate of the school.

    We pulled our son out of this school and placed him in another school. This school truly understands how to guide students' acceptance of differences and embrace teachable moments so that bullying is a non-issue.

    I truly hope that this family gets the out-of-district placement for their daughter. However, I am doubtful that the school district will address the root of the problem.

    Everyone knows that if a dog's ears are up and its tail is wagging vigorously, it is definitely pleased to see you, but now scientists using a robot have found that the way dogs use their tails is more complicated than we thought, and that dogs which wag them to the left may he more friendly. The animal psychologists discovered that when real dogs approached a life-sized robot dog, they were less cautious about it when it was wagging its tail to the left, while if it was wagging its tail to the right, far fewer dogs approached it in a confident manner.

    In the first experiments, 56 percent of the animals approached the model without hesitation when the tail was wagged to the left, while only 21 percent did so in the other situation. When the researchers excluded (排除) owners from being present, the result were: 31 percent of the dogs approached continuously when the tail was wagging to the left, while only 18 percent did so when it was on the right.

    Animal psychologist Roger Mugford said it added to the growing evidence that does were even more complicated communicators than the animals more closely related to man such as monkeys. He said, "We know that dogs, in a sense, have languages, but it is more complicated because it is not just them wagging their tails, but also giving out chemical displays."

    He adds, "The research confirms earlier studies suggesting that dogs, like humans, had a left-side preference. If you are going to present a signal to a dog, it is sensible to put it on your left-hand side because that is where dogs, unlike most other animals, tend to look. It is another example of the similarity between dogs and humans. They are a lot more human than we give them credit for."

Do you continue to be healthy in social isolation? NASA is looking for people to spend 8 months locked in a Russian lab for a new experiment.

When humans go to the moon and travel to Mars, they will need to be prepared for long-term space travel and even longer stays on these far-off destinations. Currently, NASA's Artemis program aims to land humans on the moon for the first time since NASA's Apollo 17 mission landed in 1972.

While the moon is the main goal of NASA's Artemis program, the agency's larger goal is to send people to Mars. But long-term space travel and habitation won't be easy. Such missions will present both physical and mental challenges as astronauts work to not only survive, but perform important scientific research in uniquely difficult environments.

In the upcoming NASA-Russia experiment, a group of people will live in a closed facility at Russia's Institute for Biomedical Problems, which is in Moscow. This habitat facility was used in2011 for notable series of Russian mock (模拟的) Mars missions known as Mars 500. During these missions, groups of people spent 520 and 105 days on two separate missions in the facility.

The facility, according to the statement, will have "environmental factors similar to those astronauts are expected to experience on future missions to Mars". The group of people will spend 8 months living together in isolation and working on scientific research.

By living and working in this Mars-like environment, participants in this study will help NASA researchers better understand the psychological and physiological (心理和生理的) effects of isolation. These missions help researchers not only perform relevant science experiments but also see how people might get on under strange conditions for long periods of time.

So, if you're finding that living in social isolation works for you, you might be particularly well-suited for living in a Mars-like environment and this could be for you. But first, you have to qualify. NASA is looking for "highly motivated" Americans between the ages of 30-55, who must speak both Russian and English fluently and have a Master of Science, Doctor of Philosophy, Doctor of Medicine, or military officer training. Applicants with other related experience may also be considered. Those who are chosen to be a part of this group will be paid for their work.
