Tens of thousands of drone (无人机)owners will have to register their devices for the first time under regulations designed to safeguard privacy.

Rules introduced yesterday require all drones that are fitted with cameras to be logged with the Civil Aviation Authority (CAA). Anyone who fails to do so faces being taken to court and fined up to £1,000. Drones heavier than 250g already have to be registered with the CAA, which costs £9 and must be renewed annually, but the new measures extend this requirement to all devices, including the lightweight models that are used by hobbyist pilots.

The move comes after sharp rise in the number of drones bought by enthusiasts or those operating them for commercial reasons, such as to inspect infrastructure or for photography and filming.

However, the rise has prompted concerns over privacy, with fears that drones are being used to spy on private residences and other buildings. It has also led to an increase in the number of near-misses between drones and other aircraft, including commercial passenger jets. The latest figures show 531 near-misses involving drones were logged in the past decade, including 125 recorded in 2019.

By law drones are supposed to be operated within an operator's line of sight. They have to remain below an altitude of 400ft to avoid interfering with aircraft and flown at least 164ft away from people and buildings. The government has already toughened up regulations in recent years. This includes requiring all operators to pass an online test before being allowed to fly devices. Other changes to the regulations include allowing drones that weigh up to 25kg to be operated, compared with a previous limit of 20kg.

Devices will also fall into three new categories of risk --high, medium and low -- depending on how they will be flown. Low-risk drones, including those typically used by hobbyists, will have operational limitations but will not need authorisation （授权）for flights. Authorisation is needed for larger medium-risk and high-risk drone flights, which are typically carried out in more complex environments, including those beyond the operator's line of sight, which is banned under normal circumstances.

Christian Struwe, the director of public policy, said of the new regulation: "It simplifies different processes and allows customers to travel from country to country without having to worry about different rules in different foreign locations"

Princess culture is less about a princess lifestyle, and more about great-depth of character, serving as a beautiful reminder of worth—whether a girl is a princess or not. In Frances Hodgson Burnett's A Little Princess, Sara Crewe survived her many tragedies and hardships by remembering "I am a princess. All girls are… even if they aren't pretty, or smart, or young. They are still princesses. " Whether child or adult, all can benefit from the belief that no matter their circumstances, they always have value—that true self-worth goes beyond appearance or environment and is found deep within. No matter how difficult our circumstances are, princesses encourage us to remember our worth.

Spend much time with a four-year-old girl in the U. S and you will likely see some sort of princess play, whether it is dressing up, acting out stories, or playing with princess-themed toys. This particular type of pretend play is very important to children. Lindsey and Colwell found that children who regularly engage(参与)in pretend play have more positive emotions with peers(同龄人), score higher on emotional understanding, and are better at emotional regulation one year later. Research suggests that princess play specifically can lead to rich experiences for children as they expand on the stories of familiar characters.

Princesses also provide examples of "women who rule", showing women and girls that they can be accepted as the heroines of their own stories and lead with wisdom and maturity( 成熟). In other words, princesses inspire potential.

Adults often think of princesses in a negative way someone who is too proud or crazy about their appearance. But in children's imagination, the word "princess" allows them to think about what they can become. Maybe they won't save the world, but they will defend their values. Maybe they won't have the perfect figure, but they can develop the confidence to move beyond appearance.

English businessman Richard Branson made history on July 11, 2021 as he and three other crewmates became the world's first space tourists. The flight was made by a spacecraft named VSS Unity that was built by Branson's company, Virgin Galactic. The flight lasted slightly more than an hour, and took Branson and crew to an altitude（海拔） of 53. 5 miles above the Earth, just a little above the boundary（边界） of space which lies 50 miles above the Earth.

At that height, the atmosphere turns into the black of outer space and the Earth becomes a bent ball of blue. Travelers also exhibit weightlessness as there is no gravity, the force that keeps our bodies walking on the Earth's surface. Therefore, Branson and his fellows were able to float around in VSS Unity while enjoying the views. They were able to do that for three minutes before the spacecraft began its downward journey. It landed back at Virgin Galactic's space port in New Mexico, United States, which is the same place from where it took off 90 minutes ago.

On landing back, Branson said, "I have dreamt of this moment since I was a kid but honestly, nothing could prepare you for the view of the Earth from space. It was just magical. I'm just taking it all in, and it's unreal."

July 11's flight is the start of space tourism for one and all. In early 2022, customers who could afford a ticket for a quarter of a million dollars could line up for a seat on a trip to space. And guess what—they will have a choice of spacecraft. Jeff Bezos, who owns a famous company, is all set to launch himself into space on July 20 on board a spacecraft built by his new branch company Blue Origin. Blue Origin will also carry tourists to space.
