The uncrewed Roscosmos Soyuz MS-22 spacecraft will undock from the International Space Station on Tuesday, March 28.

The spacecraft will depart the space station’s Rassvet module at 5:57 a.m. EDT, heading for an automated, parachute-assisted landing in Kazakhstan at 7:45 a.m. (5:45 p.m. Kazakhstan time).

NASA will provide coverage of the undocking and departure from the station beginning at 5:30 a.m. on NASA Television, the NASA app, and the agency’s website. Watch the departure coverage online at:

There will be no televised coverage of the deorbit burn or Soyuz landing. The station blog will be updated after the events occur.

NASA astronaut Frank Rubio and Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin launched aboard the Soyuz MS-22 in September 2022. Following an external coolant leak detected on the Soyuz MS-22 spacecraft in December, the replacement Soyuz MS-23 was launched to the space station on Thursday, Feb. 23, to return Rubio, Prokopyev, and Petelin later this year.

Earth Hour is an annual event that takes place on the last Saturday of March. During this event, people around the world turn off their lights for one hour to raise awareness of climate change and the need for sustainable living. Here’s a brief history of Earth Hour and why we observe it:

Earth Hour was first observed in Sydney, Australia in 2007. The event was organized by the World Wildlife Fund (WWF) as a way to raise awareness of climate change and encourage people to take action to reduce their carbon footprint. During the first Earth Hour, more than 2 million people in Sydney turned off their lights for one hour. The event was a huge success, and it has since become a global movement.

Today, Earth Hour is observed in more than 180 countries around the world. Millions of people participate by turning off their lights for one hour, from 8:30 to 9:30 p.m. local time. Landmarks such as the Eiffel Tower in Paris, the Sydney Opera House, and the Empire State Building in New York City also participate by turning off their lights.

The goal of Earth Hour is to raise awareness of the impact that human activities have on the environment and to encourage people to take action to reduce their carbon footprint. Climate change is one of the biggest threats facing our planet today, and Earth Hour is a way to remind people of the urgent need to take action to protect our planet.

During Earth Hour, people are encouraged to do more than just turn off their lights. They are also encouraged to make changes in their daily lives that will help reduce their carbon footprint. This can include things like using public transportation, eating less meat, using energy-efficient light bulbs, and reducing waste.

In conclusion, Earth Hour is an annual event that encourages people around the world to turn off their lights for one hour to raise awareness of climate change and the need for sustainable living. By participating in Earth Hour and making changes in our daily lives, we can all do our part to protect our planet and ensure a sustainable future for generations to come.

Turbulence is one of the most common fears that people have when flying. It is the feeling of the plane shaking or bouncing around while in the air. Turbulence is caused by the movement of air currents in the atmosphere, and it can be caused by a variety of factors such as weather conditions, jet streams, and even the shape of the terrain below.

While turbulence can be unsettling, it is important to remember that it is a normal part of flying. Pilots are trained to handle turbulence and are experts at navigating through it safely. In fact, planes are designed to withstand even the most severe turbulence, so there is no need to worry about the safety of the aircraft.

That being said, there are different types of turbulence that can affect the aircraft differently. The most common type is called “light turbulence,” which feels like a slight bump or jolt. This type of turbulence is generally not dangerous and is often experienced during takeoff and landing.

“Moderate turbulence” is more intense and can cause objects to shift around in the cabin. This type of turbulence can be uncomfortable for passengers, but it is still not a safety concern for the aircraft.

“Severe turbulence” is the most intense type of turbulence and can be frightening for passengers. It can cause the aircraft to drop suddenly or violently, and objects in the cabin can become airborne. However, even in severe turbulence, the aircraft is still designed to withstand the forces and will not be in danger of crashing.

In conclusion, while turbulence can be scary, it is a normal part of flying and poses no danger to the safety of the aircraft. Pilots are trained to handle turbulence and will do everything in their power to ensure a smooth and safe flight. So the next time you experience turbulence while flying, rest assured that you are in good hands and there is nothing to fear.
