SpaceX Lands First Successful Starship Flight

SpaceX, a private American space company, has successfully launched and landed its Starship spacecraft from a launch site in Texas. In the three previous attempts the rocket exploded during the landing phase.

The 50-metre tall reusable rocket rose to an altitude of almost 10 km over the Gulf of Mexico, then turned and descended in an upright position back to its launch pad. A small fire after touchdown was quickly put out.

The Starship rocket has three engines and can carry 100 tons of cargo into space. It is scheduled to bring NASA astronauts to the moon in the next few years. The rocket is also part of a more powerful system that will one day bring astronauts to Mars.

The successful mission came on the 60th anniversary of the first American, Alan Shepard, to travel into space.

SpaceX is owned by Elon Musk, an American entrepreneur, who plans to set up an American colony on Mars.

China Launches First Module of Space Station

China has successfully launched the first module of its space station, called Tianhe or Heavenly Harmony, from the island of Hainan. The module contains the living quarters for crew members.

After 10 missions to deliver parts to low Earth orbit, China’s space station is expected to be fully operational by 2022. It will be used for scientific and medical experiments. 12 astronauts are currently training to live in space for a longer period of time.

China’s space station will not be as large as the International Space Station ISS, but similar to the Russian Mir space station which was in operation between 1986 and 2001.

The construction of its own space station is seen as a further step in China’s ambitious billion-dollar space program. The first satellite was launched in 1970 and the first manned mission was carried out in 2003. Recently a lunar probe has brought back the first samples from the moon since the 1970s.

NASA Announces First Successful Flight On Mars

The first controlled flight of an aircraft on another planet has successfully taken place. The Mars drone Ingenuity lifted off and hovered about 1 meter above the Martian surface for 40 seconds. Because of the distance between the Earth and Mars flight controllers had to wait for three hours to find out if the experiment was successful.

The drone was brought to Mars strapped under NASA’s Perseverance rover. It was positioned 65 meters away from the rover, which took pictures and recorded videos of the flight.

Because the atmosphere on Mars is thin and there is less gravity compared to Earth, Ingenuity’s rotor blades must rotate much faster to lift the craft. In addition, the drone has an on-board navigation system and software which allows it to fly on its own.

The 1.8 kg heavy drone has two cameras on board, as well as solar-powered batteries. NASA intends to use drones on future missions to Mars to find the right landing places and gather data.

During the next few weeks NASA is planning several test flights of the Ingenuity drone.

Scientists Develop New Effective Malaria Vaccine

For the first time in history scientists have made a major breakthrough in malaria treatment. In a lab in Burkina Faso scientists from Oxford University have created a vaccine that is 77% effective in treating the deadly disease. Up to now researchers have only been able to come up with a vaccine that is about 50% effective.

The experimental vaccine, given to 450 small children, showed promising results. Now scientists plan to treat 5000 children with the new drug in the last phase of the trial. If all goes well, millions of doses of the vaccine will be produced in India.

Malaria is one of the deadliest diseases on our planet. Over 200 million people suffer from the illness that is transmitted to people by mosquitos in tropical regions. It kills over 400,000 people each year, mostly children in Africa. According to the World Health Organization, malaria has turned out to be even deadlier than COVID-19 in Africa.

A malaria vaccine is very difficult to develop because its structure, compared to the coronavirus, is very complicated.

Earth’s Axis Shifted Because of Climate Change

Recent studies and satellite data has shown that the Earth’s axis is moving faster, due to climate change and global warming. The axis of our planet is a straight line that goes through the poles. It is not in a fixed position but normally moves slowly due to movements inside the Earth. Scientists do not completely understand how this happens.

New information now shows that the movements of the poles are going on much faster than in previous decades, mainly because of the melting of glaciers and large ice masses. This has led to more water on the surface, which pulls at the poles. The North Pole, for example, is moving slowly towards Russia. Since 1980 the poles have wandered about 4 meters.

In addition, farming has led to more and more groundwater around the world being pumped up from below. This water ends up in rivers and finally in oceans, also contributing to a change in the weight of ocean water.

Scientists say that the change in the Earth’s poles is not enough to affect our daily life, but may lead to a change in the length of daytime by a few milliseconds.
