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.
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.
SpaceX first supplied ISS with re-used spacecraft and missiles
Dragon’s reusable spacecraft has just been successfully launched by SpaceX to bring 2,000kg of supplies to the International Space Station.
On December 15, SpaceX achieved an important achievement in its history. For the first time, Elon Musk’s aerospace company successfully launched both reusable missiles and spacecraft.
Moreover, this is not a test launch. This launch of the CRS-13 has a mission to resupply the International Space Station (ISS). This shows that NASA has great confidence in SpaceX’s reuse technology.
CRS-13 was launched at Launch Complex 40 at Cape Canaveral Air Force Base.
The launch position is also very noticeable. CRS-13 was launched at Launch Complex 40 at Cape Canaveral Air Force Base, where the Falcon 9 rocket once exploded in September 2016. Speaking of the disaster, this is the first time SpaceX launched missiles here and it marks the remarkable recovery and progress of the company run by CEO Elon Musk.
In this launch, SpaceX used a Falcon 9 rocket that was used for the previous ISS resupply mission and a reused Dragon spacecraft to minimize costs. This is the first time the company has used both missiles and spacecraft to reuse in one launch.
Dragon spacecraft will bring 2,000kg of cargo to ISS. These goods include supplies for the station and research equipment for astronauts. Among the devices there are two sensors used to monitor the amount of space garbage surrounding ISS and measure the amount of sunlight coming to Earth.
The launch marks an important step forward for SpaceX, which shows that they are capable of learning from past mistakes and demonstrating their ability to perform missions with a higher level of reuse. After this launch, SpaceX will focus on preparing for the massive launch of Falcon Heavy.
