Three astronauts depart for the International Space Station

The spacecraft sent three astronauts from the US, Japan and Russia from Kazakhstan, starting a two-day journey to the International Space Station (ISS).

According to Reuters, astronaut Anton Shkaplerov of the Russian Federal Space Agency, aviation engineer Norishige Kanai at the Japan Aerospace Exploration Agency and Scott Tingle, astronaut of the US Aeronautics and Space Agency ( NASA) flew into space from Baikonur Cosmodrome launch yard at 7:21 (GMT).

The camera in the aircraft recorded the image of three astronauts raising their thumbs after flying into space. Shkaplerov’s daughter gave them a stuffed dog to monitor gravity in the cockpit.

Astronauts will undergo a two-day journey before landing at the ISS. Here, they will meet astronaut Alexander Misurkin, Mark Vande Hei and Joe Acaba, who are on duty here since September.

The International Space Station (ISS) is a spaceship the size of a football field, where astronauts live and research. It travels through space at an average speed of 27,743.8 km / hour, equivalent to 15.79 times the daily flight around the Earth.

ISS is a $ 100 billion project of 15 countries. NASA once planned to use the vehicle developed by SpaceX and Boeing to bring astronauts to ISS. Earlier, after the US-led shuttle program ended, all flights to ISS were primarily responsible by the Russian side.

NASA uses ISS to prepare for missions to bring people to the Moon and Mars, thereby studying and developing commercial flights to space, producing drugs and many other purposes.

Anxiety about an unusual sun

A super solar storm when attacking directly on the earth can cause damage of up to 2,000 billion USD.

Some recent rare occurrences on the sun have caused scientists to not find an explanation. What is happening to the sun and should we be afraid of unusual phenomena on it?

A strange phenomenon

The US Agency for Aeronautics and Space (NASA) last month published a picture of a rare phenomenon known as “curled material” near a “hole” in the sun. This physical fiber surrounds an active area on the sun’s surface. Normally, these black matter fibers appear with elongated shapes, so their curling up into each other has caught the attention of the scientific community.

“This is one of the rare times we observe the material of a circular shaped shape, although it may not have significant scientific value,” NASA officials noted.

This is not the only strange event happening on the sun over time. Earlier, in September, the phenomenon of two giant black spots appeared on the surface of the sun also made the scientific community particularly worried and concerned. With a size much larger than the earth, these two sunspots – named after RGN 2673 and RGN 2674 – can be observed from the earth without using telescopes, according to the Ocean Administration. and the US national atmosphere (NOAA). As areas with strong and complex magnetic fields, RGN 2673 and RGN 2674 have created solar halo and storms, impacted communication devices, global positioning systems (GPS) and radio signals. …

A huge solar flare was recorded on September 6

Black marks or fire circles or solar storms are not strange phenomena. Usually, they tend to appear most at the peak of the solar flare in the 11-year cycle. The current cycle of the sun, beginning in December 2008, shows that its activity intensity has plummeted and is about to enter the weakest outbreak. As expected, the sun will be the quietest at this stage. However, the events taking place in the past have shown the opposite, making scientists both excited and anxious because they do not expect to see the sun work strongly at that time.

Negative impact

Not only are they constantly appearing at unexpected times, the sun’s fire also causes scientists to worry about their size and intensity. On September 6, the sun launched two X-level fire rings (the strongest level) that lost radio signals on the earth. In particular, the second fire halo is considered the strongest intensity recorded since 2005, causing a diurnal eruption (CME) affecting the operation of satellites, communication systems and power on earth, according to the Space Weather Prediction Center (SWPC).

The above solar activities have caused some radiation storms in high latitudes of the earth, disrupting radio communications at certain frequencies. According to The Conversation, their impact also spreads to the equator and affects high-frequency communications, such as amateur radio used in emergency response and disaster relief. Data from the Australian Bureau of Meteorology show that high-frequency radio communications seems to be disrupted in raging Irma storms.

Also in these areas, communication through the global satellite navigation system (GNSS) seems to be broken. Radiation storms also force flights through the polar regions to change routes to avoid an increased radiation environment that could adversely affect human health and threaten to damage the navigation system and contact information. touch of the plane.

Meanwhile, CME formed from level X sunfire when exposed to the earth also threatens to cause other impacts on the near-earth space environment, including geomagnetic storms (still called magnetic storm). This storm is known for its potential to adversely affect satellites, earth communications technology, grid electricity, GPS / GNSS, and predict the satellite’s orbit as well as fragments in the Universe. cylinder.

The scientific world cannot explain everything that happens on the sun. However, what happened last time signaled important spatial weather events that could take place at any time during the Sun’s 11-year cycle, even at the time it was thought to be quiet. the most static.
