The spaceship named Crew Dragon of SpaceX Company with a future mission carrying American astronauts went into space in the early morning of March 2.

Since the American space shuttle was retired in 2011, American astronauts who want to go to the International Space Station (ISS) to work or return to Earth have had to depend on Russian ships. Therefore, the first test flight of a new ship called Crew Dragon is expected by Americans to bring them back to the space race autonomously.

Privateer

The launch took place at dawn on March 2 at the Kennedy Space Center in Florida. The center located next to Cape Canaveral is where America’s missions to conquer space are carried out. This place witnessed the launches of Apollo to conquer the Moon and the space shuttles of the US Space Agency (NASA) as well as the most powerful rocket in the world today belonging to SpaceX, Falcon Heavy.

One of the reasons why the test attracted attention is that the capsule was not built by the experienced NASA agency, but by the private company SpaceX run by the “wild” billionaire Elon Musk.

Under President Barack Obama, NASA called for bids from the private sector for two projects: building a spaceship that could transport goods and a ship that could transport people to the ISS, currently in an orbit of 400km. Transferring it to the private sector is not only to stimulate demand for this US industry, but also to save time in finding a replacement for the space shuttle that was put in storage because it was too expensive and too dangerous. .

SpaceX is the only company that won the bid for both projects that NASA set out to do. They have built the Dragon cargo ship, participating in transporting goods to the ISS since 2012, then transporting equipment that needs repair and waste from the ISS to the ground. The Crew Dragon ship carrying astronauts is considered a development of the Dragon ship.

Strict safety

Previously, billionaire Elon Musk was excited about his company’s bold capabilities, but in fact the Crew Dragon was tested up to 3 years late. Much of the reason for the testing delay is the strict safety requirements set by NASA. Of course, that is the top priority, because NASA does not want to repeat the tragic accidents of the space shuttles Challenger and Columbia in 1986 and 2003. 14 American astronauts died in those two incidents.

During the test flight on March 2, engineers placed only one doll in the seat of the capsule designed to carry up to 7 astronauts. The doll was personally named Ripley by owner Elon Musk, after the female protagonist of the movie Alien. The two-stage Falcon 9 rocket carried the Crew Dragon and brought it back to earth on March 8 using the remaining first stage of the rocket. According to the plan, it will automatically connect with the ISS on March 3.

If this test is successful, Nasa’s first two astronauts may go to space on a US ship from next July, according to SpaceX’s statement, but experts are still not sure.

NASA invested nearly 7 billion USD

In addition to SpaceX, private company Orbital Sciences has won the bid for an automated cargo ship project called Cygnus. In the bid to order a human spacecraft, initially about a dozen companies jumped in, but in the end only SpaceX’s project and Boeing’s CST-100 Starliner project were selected for test flights this year. .

In September 2014, NASA spent $2.6 billion on SpaceX and $4.2 billion on Boeing to carry out the project. Each company will have to carry out up to 6 space missions for NASA and at least two rounds of transporting people to and from the ISS station.

According to CBC, telescopes belonging to famous physicist Stephen Hawking’s Breakthrough Listen project to search for extraterrestrial life have discovered 15 strange signal sequences.

These signal sequences come from a radio burst source (FRB) named 121102, in a dwarf galaxy about 3 billion light years from Earth.

This is not the first time people have received signals from FRB 121102. However, recent signals have been transmitted at higher frequencies than before.

“It’s extremely puzzling and unlike any other FRB,” Paul Scholz, an astronomer who specializes in studying FRBs, told CBC.

Meanwhile, Mr. Andrew Siemion, Director of the Breakthrough Listen program, at the University of California at Berkeley (USA), explained: “Signals of this type have never been detected at such high frequencies.”

The Breakthrough Listen program has the goal of searching for signs of extraterrestrial life in the past.

This program, worth $100 million, was founded by Professor Stephen Hawking and Russian Internet billionaire Yuri Milner.

About 150 FRBs have been previously detected since 2012. Because they last only a few milliseconds and radio telescopes can only monitor a small area of the sky at any one time, only one of them wave sources are detected repeatedly.

Exactly 15 sound waves were recently recorded by the Green Bank Telescope in West Virginia (USA) on Saturday, August 26, in 5 hours.

Researchers of the Breakthrough Listen program have initially analyzed the recorded data sources and only determined that they came from one source and announced it on September 2.

For comparison, it took scientists 83 hours of observation, over a six-month period in 2016, to detect just nine signal sequences coming from FRB 121102.

“Whether or not radio bursts are extraterrestrial technology, Breakthrough Listen has contributed to expanding the frontier into a rapidly growing new area of our understanding of the universe,” said Andrew Siemion. Discuss new discoveries.

Until now, people are still debating the origin of FRBs. According to CBC, it is expected that in the next few months Canada’s CHIME telescope will begin further studies of the FRB.

But these 15 sound wave signals make scientists excited because they can collectively generate the energy of 500 million suns (to be able to travel that far into space).

In general, scientists still do not know anything about these newly recorded mysterious signals. Even earlier this year, a group of scientists at America’s famous Harvard University hypothesized that those sound waves could be “an energy source for alien spaceships”.

It is worth noting that despite his desire to understand the mysteries of the universe, Professor Hawking himself was worried about finding signals from aliens.

He said that if that really happened, it would be best “not to respond immediately” to those rumors because it would be like Christophe Colomb’s conquest of the Americas.

“One day we may receive a signal from a planet like Gliese 832c but we need to be careful before responding. An encounter with a more advanced civilization could be like of Native Americans with Colomb and as everyone knows, it ended badly,” Professor Hawking once opined in the documentary Stephen Hawking’s Favorite Places.

According to the opinion of a professor who is one of today’s top scientific geniuses, there may be alien civilizations that are more advanced than Earth’s and if they “talk to each other” the Earth will be annexed.

Originating from a call on Facebook, 3,000 Americans rushed to an area with a top-secret US military base after rumors that aliens would appear here.

A resident named Matty Robert took to Facebook to create an event called “Squall on Area 51. They can’t stop all of us”. Area 51 is a US military base in Nevada.

The event takes place on September 20 (US time). Nearly 2 million people clicked “going” (attending) this event, making authorities worry that there will be a crisis situation in the Nevada desert – considered the location of a top-secret military base of the US military.

Robert later admitted it was just a joke. This 27-year-old young man has deleted the above event organization entry. However, Robert’s joke also caused about 3,000 people to appear near Area 51 on the morning of September 20 (US time), according to CNN.

“They threatened to storm in. The officers warned them of the consequences of storming the base, so they thought again,” said Kerry Lee, Lincoln County sheriff.

Meanwhile, according to Reuters, police arrested three people near Area 51, including one Canadian, while a woman was briefly detained after trying to cross the fence into Area 51.

Police Lee said the military is still increasing guard at Area 51 due to concerns that more people will flock to this base on the evening of September 20 and on weekends.

Area 51 has long been considered the most top secret military base of the US Government. Many theories suggest that this is the place containing the remains of a flying saucer and alien bodies after a UFO accident in Roswell, New Mexico in 1947.

It was not until 2013 that the US Government confirmed the existence of Area 51. The US Federal Investigation Agency (CIA) at that time released documents proving that this base was used to test aircraft. top secret detective.

However, these documents still do not quell many people’s suspicions about Washington detaining aliens at Area 51.

Alien hunter Scott C. Waring claimed he discovered aliens in Antarctica through Google Earth, but NASA said it was just a cognitive and psychological illusion.
The existence of aliens has been a debated topic for centuries.

The more modern science and technology develops, the more people are interested in learning about this issue. Many people spend a lot of time searching for extraterrestrials.

They are called “alien hunters”.

Recently, Scott C. Waring – a famous alien hunter – announced that he had found an alien in Antarctica.

Through the Google Earth tool, Scott C Waring recorded a photo of a strange creature about 20 m high, next to a 22m high “door”.

Scott C. Waring posted on the blog ET Database and UFO Sightings Daily confirming that what he found was aliens.

However, the space agency NASA believes that the structure and other similar discoveries in Antarctica are not alien but are just the effects of Pareidolia – an inaccurate cognitive tendency that occurs when the brain tricks the eyes into an object, pattern, or meaning known to the observer. For example, seeing a face in the cloud.

This means that the “giant aliens” and “doors” that Scott C. Waring saw were just rocks or tracks in the snow.

NASA said: “Pareidolia is a fairly common psychological phenomenon. There are many examples of this phenomenon on Earth and in space.”

Although NASA denied it and many blog followers were skeptical about its conclusions, Scott C. Waring always affirmed that his findings were accurate.

“This photo was taken by a Google Earth satellite. The Google Earth satellite is an unbiased object with no agenda, not interested in anything other than recording real images reality it sees,” said Scott C. Waring.

Scott C. Waring also argued that humanity would have the strength to deal with such a shocking alien revelation if NASA acknowledged it without avoiding it or trying to deny it.

To this day, Scott C. Waring’s photo continues to be debated by science lovers around the world.

Aliens are creatures that can exist and originate outside of earth.

Belief in aliens dates back to ancient Egypt, Babylon and Sumer, through theories of cosmic origin, which considered the universe to be supernatural. The image of extraterrestrial creatures at that time was difficult to distinguish from gods and demons.

For the scientific community, extraterrestrial life can exist independently in many different places in the universe. Up to now, space research projects and the search for new habitats have paralleled the study of extraterrestrial life but have not yet yielded results.

In artistic culture, aliens are depicted in many different shapes, such as a creature much taller than humans, with a strange shape with big eyes and a pointed chin.

Recently, a “strange nebula” shaped like a blue glowing spiral appeared over New Zealand’s South Island. Many locals who witnessed this rare miraculous sight took photos and posted them on social networks, causing heated discussions among many astronomy fans. Many people speculate that this is likely a trace of aliens visiting earth.

According to Mirror, Stewart Island stargazing guide Alasdair Burns received a text message from a friend at around 7:25 p.m. on June 19, asking him to go outside and look at the sky.

As soon as he stepped outside the house, he saw a giant, blue spiral-shaped unknown object or phenomenon appearing in the dark night. Bones said incredulously: “It looked like a spiral galaxy.” giant snail, hanging in the air, slowly fluttering, very strange.”

Then he knocked on all the neighbors’ doors and invited them to watch this strange astronomical spectacle. He stood on the shared balcony with five people and looked up at the sky. Everyone was horrified by the scene. before your eyes.

In addition to Borns and his neighbors, many local witnesses also shared the photo on social networks, which immediately sparked heated debates among netizens.

Many people speculate that this is likely a trace of aliens visiting earth.

However, physicist Richard Easther of the University of Auckland commented that although this scene is very strange, in fact this is a phenomenon that occurs every time a rocket is launched and a satellite is put into space orbit. . East explains further, when a rocket ignites and spews exhaust gases, water and carbon dioxide, briefly forming an oddly shaped cloud illuminated by the sun.

It is known that on the same day, the American space exploration technology company SpaceX indeed launched the medium-sized launch vehicle Falcon 9 Block 5 (Falcon 9 Block 5) near Cape Canaveral, Florida, onto the company’s communications satellite. US Globalstar satellite communications. “2 FM15” was sent to low Earth orbit. “The shape of the satellite’s orbit and our position relative to the sun, combine to create the strange clouds we see over the South Island,” East points out.
