After spending just under a week on the space station, Boeing’s new passenger spacecraft, the CST-100 Starliner, returned to Earth this afternoon, landing unharmed with the help of parachutes and airbags in the New Mexico desert. The successful landing ended a critical Starliner test flight that demonstrated the ship’s ability to take off into space, dock with a station, and then return home safely.
The gum-shaped Boeing Starliner capsule was built in collaboration with NASA to launch the agency’s astronauts to and from the International Space Station, or ISS. The mission is part of NASA’s Commercial Crew Program, which has challenged private companies to build space taxis to transport people into low Earth orbit. But before NASA allowed its employees to board the spacecraft, the space agency wanted the Starliner to prove it could make it through all the stages of a flight to the International Space Station – without people on board.
By the end of the day, this unmanned test flight, dubbed OFT-2, concluded with Starliner taking all the important steps it was supposed to take. capsule successfully Launched into orbit May 19.travel into space on an Atlas V rocket; approach and Docked with the International Space Station on May 20.; She parted ways with the space station this afternoon before returning home. The flight was not entirely smooth. During the mission, Starliner had several problems with various thrusters, small engines used to maneuver and propel the ship through space. However, none of these problems proved fatal to the flight, and Starliner was able to complete OFT-2 as planned.
it was a lot bumpy road to get to this release. The name of this test flight, OFT-2, actually refers to Orbital Flight Test-2. That’s because it’s a test flight of the same test flight that Boeing attempted in 2019. In December of that year, it launched the Boeing Starliner without a crew on board, sending it into space on another Atlas V rocket. The Starliner caused the capsule to misfire its engines. after separation from the rocket, and eventually the spacecraft entered the wrong orbit. The problem kept the Starliner from reaching the space station, and Boeing was unable to demonstrate the spacecraft’s ability to dock with the International Space Station. Boeing had to get the spacecraft home early and managed to land the capsule at the White Sands Missile Range in New Mexico — the same spot where the Starliner landed today.
Boeing tried again last summer to launch the Starliner, but just hours before takeoff, the company stopped the countdown after learning of it. More than ten check valves are stuck and do not open properly.. Boeing has gone so far as to fix the issues, and the company says the valves are likely to be redesigned in the future. But now, two and a half years after the initial failed flight, the Starliner has finally proven that it can be launched autonomously and docked to the International Space Station, an important function that it will have to perform again and again once people are on board.
Landing is also an important task for Starliner to get passengers safely home. To demonstrate these capabilities for this flight, the capsule was delivered to the International Space Station at 2:36 pm ET, circled the station slowly, and then retired from the orbiting laboratory. At 18:05 EDT, the Starliner used its inboard thrusters to decelerate and eject from orbit, setting a course for the Earth’s surface. The spacecraft soon plunged into the planet’s atmosphere, where temperatures reached 3,000 degrees Fahrenheit. Starliner then used a series of parachutes to slow her descent before landing at White Sands on airbags to cushion her descent. It was Starliner’s second successful landing, with Boeing already offering to land the aircraft during its first failed test flight in 2019.
“This landing arrives at 5:49 p.m. CT, about six days after the mission began,” Brandi Dean, NASA Liaison Officer, said in a live stream of the landing. “Nice landing today on white sand.”
This landing caused little concern as the Starliner had several engine problems during the flight. When the capsule was launched into space last week, two of the 12 engines used by Starliner failed to reach the correct orbit. Boeing said the pressure drop in the chamber caused the engines to shut down earlier. In the end, Starliner’s flight control system was able to divert to the backup engine in time, and the capsule entered orbit as planned. However, these same thrusters were needed to de-orbit the Starliner, but it appears to be working as planned despite two failed thrusters.
There were other errors during the flight. Several different smaller thrusters that were used to maneuver the Starliner during docking also failed due to low chamber pressure. However, this did not stop the capsule from sticking to the International Space Station. “We have a lot of redundancy that didn’t really impact collision operations,” Steve Stich, NASA’s program manager for the Commercial Crew Program, said during a press conference after docking. On top of that, the Boeing team noted that some of the Starliner thermal systems used to cool the spacecraft exhibited extremely low temperatures, and the engineering team had to deal with this during docking.
Starliner is still achieving many of its goals as it docks with the International Space Station. This weekend, astronauts aboard the International Space Station opened the Starliner’s hatch, entered the ship, and retrieved cargo delivered to the station. The capsule delivered about 600 pounds of cargo to Earth, as did rocketman Rosie, a model who went inside the Starliner to simulate what it would look like when people boarded it.
Now that Starliner has returned to Earth, there is a lot of work to be done. In the coming months, NASA and Boeing will look into the shortcomings of this flight and determine if Starliner is ready to take humans into space on a test flight called CFT for a manned flight that could take place by the end of the year. . year. This would be a huge achievement for Boeing, which has lagged far behind NASA’s other commercial crew provider, SpaceX. SpaceX has already completed five manned flights for NASA aboard the Crew Dragon capsule, which carried its first passengers in 2020.
But if Starliner could fly with humans, NASA would finally have what it always wanted: two different American companies capable of putting the agency’s astronauts into orbit.
Realme has been one of the fastest growing technology companies in the market since its founding in May 2018. This young brand was born under the mighty OPPO, which is why they use a lot of technology required for their products.
However, now we are seeing the first sign that could indicate a separation of the two brands, or at least more independence between Realme and OPPO. This is after the disappearance of goods from the first official OPPO online store in China.
Realme is withdrawing its products from the OPPO Mall in China
According to ITHome, it is no longer possible to find Realme products in OPPO Mall. It is important to note that this is the official online store for Chinese OPPO products, where we can also find several OnePlus products.
Now, if the user follows any link to the Realme section, he will encounter the following message: “This product has been discontinued, we will look for other products.” Note that the tag subsection has also been removed from the application.
However, the official Realme Mall continues to operate and has the brand’s usual portfolio of products. As such, Chinese users now have to head to Realme’s independent store if they want to purchase any of their hardware.
While no reason has been put forward for Realme’s departure from OPPO Mall, the reason seems to be the young brand’s independence. This is the thesis that has received the most agreement among publications related to the technology sector.
This will not be the first time that a sub-brand has parted ways with its founding company after achieving great market success. Take, for example, the Redmi branch, which now operates independently of Xiaomi.
Realme has been one of the fastest growing brands in recent years, even with the pandemic and shrinking smartphone market. Therefore, it is not surprising that the next step will be greater independence from OPPO with its own decision-making structure.
[smartPC사랑=이철호 기자] Modern people who often look at TV or screens are prone to eye strain. Especially since in these days when remote work is becoming more and more popular due to COVID-19, more and more people are suffering from blurred vision, dry eye syndrome and eye pain as they have to work with a laptop for a long time.
So what should I do? It is recommended to relax the eyes by looking away if possible, relaxing the muscles around the eyeballs and massaging the eyes. Better yet, have an easy-to-use eye massager. Introducing Eye Massager, Woongjin’s iplex eye massager for family and health care, which the whole family can easily use.
Material – PC, nylon Battery – 3.7 V, 600 mAh Charging – Type C cable Power consumption – 1.8 W Weight – 186 grams
Foldable glasses-like design
Woongjin’s iplex eye massager is designed for use at home and in healthcare settings and has a design very similar to goggles. In fact, when the reporter wore an eye massager and looked in the mirror, it looked like he was wearing virtual reality goggles that could have appeared in a sci-fi movie.
This eye massager is able to see the surroundings just like real glasses. In the case of most eye massagers, this is different from many products that cannot be seen. Therefore, it is convenient to be able to do other things during eye massage.
It also has a foldable design. You can adjust the angle to fit your head, and you can reduce eye fatigue more comfortably by setting the eye massager to fit you with the Velcro strap. Another advantage is that it takes up less space when you put it in your bag and carry it with you.
More comfortable with vibroacupressure massage
Meanwhile, the eye massager has been divided into two types of pneumatic type and acupressure type according to the massage method. If the pneumatic method puts less stress on the human body and gently relaxes the area around the eyes, then the acupressure method is a method of cooling the internal muscles by pressing on pain points.
The third generation eye massager, iPlex eye massager from Woongjin Household & Health Care, adopts vibration pressure massager. By correctly combining the advantages of pneumatic and acupressure methods, it not only provides precise acupressure to important points, but also reduces pain during massage. Therefore, even people who are not accustomed to eye massage can comfortably relieve eye strain.
4 modes available with one button
Woongjin’s iPlex eye massager offers a total of 4 home and health modes. First, there is a dynamic mode that encourages rotation around the eyes. You can also use Vibration Mode, which massages the eye area with quick vibrations, and Sleep Mode, which relaxes the eye area with gentle stimulation. In addition, there is an automatic mode that reduces eye strain during various vibrations.
What’s more, you can switch to the desired mode with the touch of a button. Press the button on the left side of the eye massager for 3 seconds to turn the power on or off, and press once to change the mode. So you can easily switch to your preferred mode and rest your eyes.
The healing of BGM can also be heard while being massaged with sounds of nature such as the sound of water and birds. Get rid of stress at work with vibration mode or enjoy relaxing background music while having an eye massage in sleep mode before bed.
Easily charged with Type-C cable
Nowadays, most Android smartphones come with a Type-C cable. Even laptops are at an age where batteries can be charged with a Type-C cable. The Woongjin eye massager for home care and health care can also be charged through the Type-C port. which is convenient.
It is more convenient to use as it is compatible not only with charging with the included Type-C cable, but also with cell phone chargers. Charging completes in less than an hour, and since it can be used an average of 15 times, you don’t have to worry about battery life while massaging.
Woongjin Eye Massager for iPlex home health and wellness, have you tried…
During the closing of the July issue, the reporter decided to try the Woongjin Household & Health Care iPlex eye massager. I was able to wear them comfortably like ski goggles by opening the eye massager and adjusting the Velcro to fit my head. The weight approached, so there was no discomfort during use.
When the power is turned on, massage starts with sound. First, in automatic mode, I felt pressure and vibration around my eyes. This seems to be suitable when you want to relieve eye strain quickly. In vibration mode, the acupressure point of the massager presses on the area around the eyes according to the scheme. I was worried that the pressure would be too strong, but I was able to comfortably enjoy the massage without pain.
In vibration mode, the wide eye area was more comfortably relaxed with 3D stereo vibration, while in S sleep mode, eye fatigue could be reduced with gentler stimulation. Listening to the sounds of nature, such as background music, during the massage, I almost fell asleep in the office.
During the massage, I had to go to the bathroom briefly, so I left with the massager. There was a safe view part inside the massage function part so that I could get a massage safely even when I left the office.
Woongjin Home & Health Flexible Eye Massager is a pressotherapy type eye massager, which can relieve eye fatigue more comfortably in 4 modes. Unlike other eye massagers, the field of view is safe, so it is safe and convenient to use. You can also hear background music during the massage.
Therefore, Woongjin Family and Healthcare’s iPlex Eye Massager is suitable for consumers who are looking for an eye massager that the whole family can use to relieve eye fatigue comfortably. Price 79,000 won based on the lowest online price as of July 1st.
NASA photographed the crash site of a mysterious rocket that crashed on the far side of the moon in March, and an unidentified spacecraft left behind a strange double crater that has puzzled scientists.
Pictures of the crash site were taken by NASA’s Lunar Reconnaissance Orbiter (LRO) on May 25. breast June 24. The images show that the lost piece (of which the origin is still disputed) somehow created two overlapping holes when it collided with the other side of the ship. lua Traveling at 5,770 miles per hour (9,290 km/h).
Unexpected twin wells add an extra layer of weirdness to the mystery that has baffled space watchers From January, when Bill Gray, an American astronomer and software developer who tracks near-Earth objects, predicted that some space debris in orbit would collide with the far side of the moon within a few months, Live Science previously reported. When Gray discovered the wreckage, he assumed it was the second stage of the Falcon X rocket that Elon Musk’s SpaceX launched in 2015. But subsequent observations and analysis of orbital data showed that the object was The upper stage of the Chinese rocket “Chang’e 5-T1” was commissioned.Spaceship (Named after the Chinese goddess of the moon.) which was launched in 2014. However, the Chinese authorities disagreed, claiming that the upper stage of this rocket burned out. Terra Joseph many years ago.
Although scientists could not directly observe the moment of impact, experts predicted that the ejected rocket stage would hit the lunar surface in Hertzsprung crater on the far side of the Moon on March 4 at 7:25 am ET (12:25 pm). GMT). The LRO observations show the retreat of the Moon – the eastern crater is 18 m wide and the western crater is 16 m. Had NASA’s LRO been positioned to film the impact, it would likely have documented a lunar dust cloud hundreds of kilometers high.
Scientists are still speculating what could have formed two craters. NASA officials have said one possibility is that the craters formed from a piece of debris with two large masses at either end, although this scenario is unusual.
“Typically, the expended mass of a rocket is concentrated at the end of the engine, while the rest of the rocket stage consists mainly of an empty fuel tank,” the statement said.
Is this really a Chang’e 5-T1 booster?
Because the booster is likely to completely disintegrate on impact, it’s unclear if examining the craters will provide significant clues to its controversial source. But some astronomers believe that much of the mystery has already been solved. Grey wrote on your blog Shortly after the images were released, the object was finally identified as the Chang’e 5-T1 amplifier.
“I am absolutely convinced that nothing else can be,” Gray said in an interview with Live Science. “At the moment, we rarely have something so certain.”
Gray made his first prediction of the disputed debris hitting the Moon after it was seen falling into space in March 2015. , Arizona, which is scanning our space region for dangerous asteroids that could hit Earth. However, WE0913A was not about sunAs asteroid But instead, it revolved around the Earth. Gray suspects that the body is made by human hands.
Mistaking the mysterious debris for a SpaceX Falcon 9 rocket, Gray went back to the data and found that another spacecraft was close to the debris path to the moon: the upper stage of China’s Chang’e 5-T1 mission, which launched in October. 2014 as part of the original mission to send a test capsule to and from the Moon.
Chinese Foreign Ministry officials deny that the space debris is theirs, insisting that the Chang’e-5 rocket actually burned up during its return flight to Earth in 2014. A similar rocket. From the 2020 mission, he landed on the moon for the first time. March 1 The US Department of Defense Space Command, which tracks space debris in low Earth orbit, made a statement They say that the Chinese rocket of 2014 did not leave orbit.
Gray believes his orbit data, which matches almost perfectly with the Chinese rocket’s initial trajectory, is crucial.
“A huge number of lunar missions are in orbit; his inclination means that in the past he was bound for China; it was heading east in the same way as the Chinese lunar missions; and its estimated launch time is within 20 minutes of the Chang’e 5-T1 rocket,” Gray said.
According to Gray, an amateur radio satellite (or “Cubesat”) was connected to the Chang’e 5-T1 for the first 19 days of its flight, and the trajectory data sent from that satellite matched exactly the current trajectory of the rocket debris. . Others have also identified important evidence supporting Gray’s conclusion; NASA’s Near-Earth Object Research Center, NASA’s Jet Propulsion Laboratory confirmed Gray’s analysis of the orbital data, and a team at the University of Arizona identified the rocket as part of the Chang’e 5-T1 mission by analyzing the spectrum of light reflected by coatings on the Earth’s surface. crushed rubble. .
While this is the first unwanted chunk of alien space to inadvertently collide with the Moon, it’s not the first time an artificial satellite has crashed there. In 2009, NASA’s crater detection and monitoring satellite was deliberately launched towards the south pole of the moon at 9,000 km/h, releasing a plume that allowed scientists to detect the chemical signatures of water ice. NASA also disposed of Apollo’s Saturn V rockets by launching them to the moon.
Gray said the confusion over the object’s identity highlights the real need for space agencies and private companies around the world to develop better procedures for tracking the rockets they send into deep space (which would also prevent these objects from mistaking the object as dangerous to Earth). asteroids). . .
“From my selfish point of view, this will help us better track asteroids,” Gray said. “The care given to LEO satellites has not been applied to LEO satellites because people have found it doesn’t matter much. And I hope that the United States is now considering returning to the moon and other countries sending their things there, which may change. Situation”.
