Astronauts go to bathroom just like everybody else. However, it can be tricky in space because gravity is so weak that people and objects appear to be weightless. It means that toilets cannot flush(冲洗) the same way that they do on Earth. So we have started a competition to get ideas from around the world to develop a new space toilet that would work aboard the International Space Station (ISS) as well as on Moon.

The competition, titled “NASA’s Lunar Loo Challenge”, has a total prize of $ 35, 000 to be shared by winning teams. Anyone above 14 can apply to this challenge, and the winning design will receive a $ 20, 000 reward. The second-place design will win $10, 000, and the third-place winner will win $ 5, 000.

The competition also includes a junior category(类别) in which anyone under the age of 14 can apply with their creative space toilet ideas. Winners in this category will receive public recognition and our souvenirs.

Toilet Design Requirements

Designs should take up no more than 1.13m3 of space.

The space toilet has to be able to hold at least 1.5kg human waste.

The final requirement is that the system must be able to get rid of the waste and be cleaned in five minutes or less.


We hope this challenge will result in new ways to deal with human waste in outerspace.
【小题1】What can a junior winner get from the competition?

The Berkshire Riding Centre Ltd is a highly recommended riding school. Everyone is welcome. Whether you are an absolute beginner or have dreams of becoming an Olympic champion, we can design the right riding lesson program for you.

Riding lessons for beginners

Private lessons

We offer 1-to-1 private tuition (讲授) for riders of all levels. We start beginners with half-hour private lessons while they learn the basics and build their confidence. The more experienced riders will benefit from personal tuition too. Whether you want to improve specific aspects of your riding, or just enjoy riding, private lessons are tailored to your specific requirements.

Group riding lessons

We offer broad range of group riding lessons, from child or adult beginner to advanced dressage (花样骑术) lessons and jumping lessons. Call the office to discuss the weekly Group Lesson Schedule on 01344 884992.

Riding lessons on your own horse

We also welcome horse owners who would like to bring their own for either one-off lessons or a concentrated course of lessons to improve their riding. Your horse is going or to prepare you both for competitions. Pricing is the same.

As an alternative to online colleges, these online learning platforms tend to be a little more flexible and may even offer more specific or unusual classes you can’t find at a traditional college, but it’s important that you compare your options to find what’s best for you.

Udacity

The programs of the platform mainly refer to web development, programming, cloud computing and data science. Each program includes hands-on practice, real-world applications and examples, individual code reviews, and real instructors and career coaches who can address your individual needs. It’s about $ 399 monthly, or roughly $ 597 if you buy the full four months at once.

MasterClass

Although MasterClass offers more than just creative courses, its well-chosen offerings are the ones that put A-list actors, writers, artists, musicians, and more in the teacher’s seat. Most courses have around 20 lessons. Its courses are video-based, with practical advice and demonstrations mixed in with straightforward lectures, workbooks and class discussions. The price is about $15 per month for unlimited access, but you have to sign up for one year at a time.

EdX

Real college courses, created and taught by real college instructors, are available in a variety of fields and topics. The big selling point for EdX is that the majority of their courses are free—but there’s a catch. If you’re just taking the class for your own learning experience, the free version will probably work, but if you want to have formal verification(认证)for professional reasons, the “verified certificate” option costs about $ 49 per class.

Pluralsight

Designed with working professionals in mind,   Pluralsight offers courses in subjects like software development, data science, information security and more. Regardless of how many classes you want to take, the price is about $ 30 per month for a personal plan(you can enjoy a 10% discount for a complete year).
