NASA has announced that two astronauts from International Space Station (ISS), will perform a spacewalk outside of the station in a new development. This spacewalk will be used to prepare hardware for new solar panels that will be installed as part of the ongoing power system upgrade at the Hubble Telescope. This article will provide all the details about the spacewalk. NASA will also live stream the event online.

International Space Station (ISS) running, NASA will be bolstering its power upgrade program with the help of two astronomers. They will be performing a spacewalk on Wednesday in order to replace an external battery charger. This upgrade is necessary due to the age of the ISS and the growing demand for power from the various modules.

Two NASA astronauts will conduct the spacewalk from the ISS on Tuesday. Kayla Barron, Raja Chari, and others will participate in the U.S. EVA number 79 spacewalk. They will continue to work on improving the station’s power systems. NASA has informed that the spacewalk will take place over six hours.

What does this mean for the station?

NASA has announced that it will be bolstering the International Space Station’s power upgrade program with the addition of two new astronauts. These astronauts, Drew Feustel and Ricky Arnold will perform a spacewalk on Wednesday in order to help install additional batteries and cables. The station currently relies on solar power for energy, but these upgrades will help to ensure that the station can continue to operate safely and effectively into the future. This is good news for the station, as it means that its power supply will be improved and its functionality increased.

What can you expect from the spacewalk? How do you live to stream it?

They will be installing brackets, struts, and other components to allow for future solar arrays to be added outside the space station. NASA TV will live to stream Tuesday’s spacewalk. NASA TV will stream the entire spacewalk live from your home. You can also watch the embedded video by going to the NASA website. NASA has set the spacewalk for March 15th at 4:00 p.m. IST (3:30 a.m. PT). The spacewalk will begin at 8:05 AM. ET (8:35 p.m IST)

This power upgrade is sorely needed; the ISS has been in operation since 1998, and its power systems are starting to show their age. The new batteries and wiring will help to improve the station’s energy efficiency, as well as its overall performance. In addition, this upgrade will help prepare the ISS for future missions, including crewed flights to Mars.

When will the spacewalk take place?

The two astronauts, Peggy Whitson and Jack Fischer will perform the spacewalk outside the ISS on Wednesday. This is a major milestone in NASA’s efforts to upgrade the power system on the ISS. The astronauts will replace an obsolete power control unit with a new one, and they will also install a new adapter cable. This spacewalk is expected to last for about six hours.

NASA’s Curiosity Rover captured a close-up photo of a small, flower-like mineral deposit that is located on Mars. The image of the mineral flower was taken by the Curiosity rover. It bears some resemblances to living organisms. It isn’t alive, however. Curiosity Rover captured this image near the AeolisMons (Mount Sharp), a martian mountain that forms the central peak of the Gale crater. The above was taken on February 25, 2022. You can find the official release here.

NASA’s Curiosity rover has photographed a Martian surface rock that appears to be flower-like. The image was taken on January 5, 2019, and was shared by the rover’s Twitter account. The rock is about 2 inches wide and is located in the “Rocknest” area of Gale Crater. This is not the first time that a flower-like rock has been spotted on Mars; in 2012, the Opportunity rover photographed a rock nicknamed ” jellyfish.

In a recently released photograph by NASA’s Curiosity Rover, a small, flower-like rock can be seen on the Martian surface. The rock is only about 6 inches wide and is located in the Marias Pass region of M. Initial speculation is that the rock may have been formed by an ancient riverbed, as the Marias Pass region is known to have been very watery in the past.

Curiosity Rover:

Curiosity launched on Nov. 26, 2011, and landed in Gale Crater, on Aug. 6, 2012. It continues to explore the Martian surface and provide valuable information to researchers. Curiosity has spent more than 2,800 Sols (Martian days) on Mars, taken over 700,000 raw photos, and covered 14 miles of the planet’s surface. Curiosity has a radioisotope energy system. This system generates electricity from the radioactive decay heat of plutonium.

NASA states that this power source has outlived its operational life expectancy of at least one Martian-year or 687 Earth days. Curiosity’s eight-year tenure on Mars is proof of its design.

NASA’s Curiosity rover has photographed a strange, flower-like rock on the Martian surface. The rover’s Mastcam took the photograph of the rock on January 24, 2019. The rock is about 2 feet wide and has delicate petals that curve inward. Scientists are still trying to figure out what the rock is and how it formed. Scientists believe that the rock may have been formed by an ancient river or stream.

NASA’s Curiosity rover has photographed a Martian surface rock that has been interpreted as looking like a flower. This latest discovery is just one more exciting example of the many wonders that continue to be uncovered by the rover as it roams across the Martian surface. The images of the flower-like rock were taken on March 18, 2015, and were subsequently published online by NASA on April 6, 2015.

Researchers from The University of Manchester were able to create a transuranium compound where the central metal, here called neptunium forms multiple bonds to one element. This breakthrough is crucial for the clean-up of nuclear waste.

Report in the journal Nature Chemistry that a team of researchers from The University Manchester and the European Commission Joint Research Centre Karlsruhe successfully created and characterized the long-awaited transuranium chemical bonds scenario in an isolable substance.

With decades of extensive research, the study of multiple metal-element bond interactions is a huge area of chemistry research. It has been a long-standing field of chemistry research that has sought to understand chemical bonds, reactivity, and separations applications. There is a lot of interest in understanding covalency in chemical bonding in extraction studies. This could help in the separation and cleanup of nuclear waste.

However, while multiple metal-element bond investigations are well documented across the Periodic Table up to uranium (the heaviest element to naturally occur in significant amounts), investigations involving transuranium components, which are elements that come to the following uranium on the Periodic Table, such as neptunium have been limited due to the necessity to perform work on radioactive elements in specialist facilities.

Due to the limited experimental work in transuranium-element multiple bonds, there is little knowledge transfer from these fundamental studies into potential separations applications.

Examples of transuranium-element multiple bonds chemistry have been found. These include two or more elements multiple bonds to a transuranium Ion to allow for sufficient stabilization to allow isolation of the compounds. These linkages cannot be examined in isolation due to the presence of multiple bonded elements. This complicates their analysis. It has not been possible to access transuranium compounds with only one multiple bond to an element stable enough to isolate. This makes it difficult to experimentally verify or disprove theoretical predictions.

The researchers were able to prepare a complex that contained a neptunium-oxygen ion and multiple bonds to one oxygen atom using specialist handling equipment. It was important to carefully design the supporting, cage-like organic binding framework that included four stabilizing nitrogen donors as well as a large silicon-based flanking group to help protect the neptunium oxygen bond and allow for its isolation.

The researchers extended their prior work on uranium to neptunium and were able to make previously impossible comparisons. They were surprised to discover that the neptuniumoxygen complex has greater covalent chemical bonding than an isostructural-uraniumoxygen complex. This is the opposite of predictions and highlights the difficulty in making predictions in this area.

The research was coordinated by Professor Steve Liddle (Co-Director of The University of Manchester’s Centre for Radiochemistry). He stated that the work was possible because of the collaboration between international specialists and the talents of the researchers involved in the study.

This was difficult work experimentally. It would not have been possible without three leading institutions combining their strengths to embrace our interdisciplinarity research approach. But it has been crucial because this work already highlights how predictions can easily be broken down in this complex area. This shows how important it is to experiment and test theories in order to establish benchmarks for the future.

Through the study of metal-element multiple bonds, thorium and molecular uranium chemistry have made great strides in recent years. However, transuranium science is still far behind because of the difficulties of working with these elements experimentally. This research shows that transuranium analogs can now be studied more widely, which opens up new opportunities for actinide science.

While NASA launched a mission that will deliberately crash into an asteroid, space enthusiast Elon Musk has something else in his mind. The SpaceX CEO sees NASA’s DART mission as an opportunity to avenge the extinction of dinosaurs from the Earth. Musk in a tweet to NASA said that the space agency will avenge an event that occurred million years. It is believed that an asteroid had hit the Earth causing the elimination of dinosaurs from the planet. Musk referred to this event to say that NASA’s spacecraft will avenge the wipeout of the creature. Past studies said that dinosaurs lived on the planet more than 65 million years ago. But dinosaurs became extinct because of the impact of asteroids hitting the Earth.

The DART is a planetary defense mission. The DART spacecraft will slam into an asteroid. It will demonstrate the asteroid-deflecting technology. The test is important as the technique could be used in the future to cut the risk of space rocks hitting the Earth. The impact generated by the spacecraft will change the motion and direction of the asteroid. According to NASA, the DART is the first such mission. It will showcase the kinetic impactor technique in space. The spacecraft will hit Didymos and its moonlet Dimorphos even as NASA said that the system poses no threat to Earth. As per the date set by NASA, the spacecraft will slam into Didymos and Dimorphos in September next year. The spacecraft is carrying an autonomous targeting system.

The asteroid that led to the disappearance of dinosaurs had originated from the outer half of the main asteroid belt in the solar system. The impact was such that it caused a massive global extinction event on the Earth. The object was approximately 9.6 km wide. When the space rock made sudden contact with Earth, it wiped out dinosaurs and more than 75 percent of animal species on the planet. NASA said that the main purpose of the DART mission is to make Earth ready to counter any threat that emerges from bodies from space.

Russia has defended its anti-satellite test. The country was facing flak for its test. The test created space debris. Russia has now said that its test poses no threat to the International Space Station. It said that the ISS is intact and doing science experiments. According to NASA, the test created debris and therefore increased the risk of hitting ISS and other satellites. Russia had on November 15 launched a direct-ascent anti-satellite. The satellite collided with a defunct satellite in low Earth orbit. The collision generated debris. NASA said that more than 1,500 pieces of orbital debris. Besides, it also generated thousands of small pieces of debris. It is said that the debris can threaten the ISS and other space activities.

The collision forced the ISS control team to wake up the ISS crew soon after the collision. They were notified about the satellite breakup in space. The astronauts aboard the laboratory were asked to take safety measures to protect themselves in any adverse situation. The crew took shelter in Soyuz and Dragon vehicles. The vehicles are currently docked at the ISS. They remained inside the vehicles for around two hours. The rotating laboratory passed through a field of debris that was created by Russia’s satellite breakup. Seven astronauts and cosmonauts are currently present on the ISS. Defending the test, Russia’s Ministry of Defence said that fragments pose no threat to the ISS and other space activities.

Russia said that the debris generated from the collision has moved away from the orbit of the space station. The ISS orbits around the Earth at an altitude of 400 km. According to LeoLabs, the altitude of debris is estimated to be 440 to 520 km. LeoLabs is a space debris tracker agency. NASA condemned Russia’s actions. It described the test as dangerous and irresponsible behavior. Russia is also a partner on the ISS. However, Russia has said that it will exit the program soon. The country has plans to set up a new space station. It will be called Russian Orbital Service Station. The construction is likely to begin in 2025. The country said that the proposed space station will feature next-generation modules.

Private aerospace company SpaceX has completed the second full astronaut mission for NASA. Four NASA, ESA, and JAXA astronauts have returned to Earth from the International Space Station. They flew back aboard the Crew Dragon spaceship. The capsule landed off the coast of the Gulf of Mexico. The four astronauts returned home after spending 200 days at the rotating laboratory. They returned eight hours after leaving the ISS. The return has now paved the way for SpaceX to launch the next four astronauts to the ISS. The four returned astronauts are Thomas Pesquet of ESA, Megan McArthur and Shane Kimbrough of NASA, and Akihiko Hoshide of JAXA.

SpaceX launched the Crew-2 in April. The four astronauts conducted spacewalks, undertook maintenance activities, and performed science experiments at the ISS. They also grew hot chilis during their stay in space. The Crew-3 mission will be launched with four astronauts from NASA and ESA. The three are Tom Marshburn, Raja Chari, and Kayla Barron. The ESA astronaut is Matthias Maurer. Their mission was originally slated to launch on Halloween. But the launch was delayed by NASA due to weather. The space agency also said that one of the astronauts faced some minor medical issues just before the launch. It didn’t disclose more about the medical issue.

According to NASA, the Crew-3 astronauts are under quarantine at Kennedy Space Center. It said that the Crew Dragon spaceship and Falcon 9 rocket are in good condition. The Crew-3 astronauts will spend six months at the space station. They will likely return in April next year. This will be the fourth flight of a Crew Dragon spaceship with astronauts and the third crew rotation mission. NASA said that the four astronauts will conduct many additional experiments at the ISS. They will push the effort to test exploration risks in space. They will also demonstrate technology for deep space exploration. NASA specified that experiments would include human research and rodent research on the space station. The mission is also crucial for the testing of new upgrades to the ISS’ Environmental Control and Life Support System.

For many decades, scientists have been saying that humans are almost 99.9 percent identical to each other and it is just that 0.1 percent that makes the difference. They have said that only a 0.1 percent difference is responsible for people’s unique looks and the difference in their susceptibility or resistance to diseases. As per the experts, gathering more information about these special genes can help develop new drugs and treatments. A team of experts from the Academy of Athens has been searching for people across the world who might be resistant to the SARS-CoV-2 virus. Experts have said that some people’s genes might hold the keys for better treatment of COVID19. The lead researcher of the study Evangelos Andreakos has said that the start of the SARS-CoV-2 virus on a global scale has offered yet another description of scientific diversity in people during the course of infection that ranges from asymptomatic infections to fatal infection. He has said that the understanding of the pathophysiology of life-altering COVID19 infection has grown further since the first case has come to light in December 2019. But, experts still do not know much about the human genetics and immunological source of innate resistance to the virus. The lead author has said that although scientists have not been able to find much detail about inborn resistance, however, that does not imply that it does not exist.

The authors of the study have said that they have seen that at times, the whole family tests positive for COVID19 but a member of the family turns negative for the virus. They have said that there have been multiple reports of people who have somehow have been able to avoid the virus despite being exposed to the virus multiple times. Experts who have been involved in the new study have done another study last year that has shown that people who have blood type O have appeared to be slightly resistant to the SARS-CoV-2 virus and severe disease. There have been other studies that have analyzed proteins such as the ACE2 receptor or TMEM41B that the virus needs either to enter human cells or replicate itself inside the human cell. The authors of the study have proposed a strategy to identify, engage, and genetically test those individuals who might be naturally defiant to the virus. They have said that experts need to ponder on uninfected household contacts of people who have been diagnosed with symptomatic infection. Then the focus will shift to those people who have been exposed to an index case without wearing PPE (Personal Protective Equipment) for at least one hour per day within the first 3 to 5 days of disease symptoms emerging. Four weeks after the exposure, these people need to be screened for negative PCR tests and negative blood work. This screening needs to be done to analyze T cells to verify that these people have not been infected with the virus in the past.

The authors of the study have said that they have already enrolled nearly 400 participants who have met their criteria for being enrolled in a resistance study cohort. They have said that they are still looking for more participants. People from across the world can enroll in the study after meeting the criteria for the study. Health experts who have been involved in the study have said that antiviral treatments, COVID19 shots, and a better understanding of the pathogen, life has returned to normal in some parts of the world, however, the SARS-CoV-2 virus is going to remain with people for a long time. The lead author of the study, Evangelos Andreakos has said that finding those people who are blessed with some genetic benefits to be spared by the virus can be a boon for many people across the world, who are more vulnerable to the virus. It will be helpful as new variants of the virus might emerge as the virus continues to affect more people and spread across communities. The perspective of the authors has been released in a journal known as Nature Immunology. Many people across the world have already received an online link to participate in the study; however, first, they will need to fulfill the criteria proposed by the health experts.

The United Arab Emirates (UAE) revealed intentions to conduct an ambitious expedition to an asteroid belt by 2028 today (Oct. 5). It will be the UAE’s second interplanetary mission; the first, the Emirates Mars Mission, sent an orbiter named “Hope” to Mars in July 2020. Hope is still actively functional, and the upcoming asteroid expedition will build on its accomplishments, according to UAE authorities.

“Our aim is clear: to stimulate the growth of creativity and knowledge-based companies in the Emirates,” said the chair of the UAE Space Agency, Sarah Al Amiri, in an email today. “This cannot be accomplished by remaining stagnant; it takes leaps in vision, belief, and the pursuing of missions,” Al Amiri stated. “We began on the Emirates Mars Mission (EMM), a 6-year endeavor that was 5 times more sophisticated and difficult than the Earth-observation satellites we were constructing.”

If all goes as planned, the asteroid expedition, the name of which has yet to be disclosed, would launch at a later date. It will travel past Earth and Venus in 2029 and 2028, respectively, before reaching the asteroid belt between Jupiter and Mars in 2030. Throughout the course of its journey, the probe will investigate seven distinct asteroids up close, culminating in a landing on an asteroid in 2033. The UAE will collaborate on the asteroid expedition with Boulder’s Laboratory for Atmospheric and Space Physics at the University of Colorado, which is also a major collaborator on the Hope Mars mission. According to UAE authorities, the research aims of the asteroid expedition, as well as the equipment it will carry, will be disclosed in mid-2022.

The asteroid mission is a component of the UAE’s deliberate venture into space, which includes the anticipated delivery of the Rashid moon rover to the surface of the moon in 2022. The country believes that such initiatives would assist to develop a technological interest among its citizens as well as improve and diversify its economy, which has traditionally been largely reliant on oil exports. “Today, we are engaged in future generations,” stated Sheikh Mohammed bin Rashid Al Maktoum, vice president & prime minister of the UAE and Ruler of Dubai, one of the nation’s 7 emirates, in the same announcement. “With each new step forward in space, we generate chances for young individuals on Earth.”

A new study has said that massive floods on Mars played a crucial role in shaping the landscape. Past studies have said that water was in the liquid state on Mars before the planet dried up. The planet hosted lakes similar to Earth’s. The University of Texas researchers said that water overflowed crater lakes on Mars. This overflowing of water designed the landscape the way it appears today. Water carved deep chasms on the surface. This landscape-changing activity happened persistently on the Red Planet for a long time. Overflowing of water even eroded sediment in Lake Superior and Lake Ontario.

Researchers said that such flooding was more common on Red Planet than previously assumed. It has even more craters than Earth. It means that the Red Planet was very wet and crater lakes were very common. Researchers said that the Martian lakes breached the crater walls due to the overflowing of water. This caused floods on the surface. The surrounding landscapes were flooded. The study included more than 260 craters lakes that breached their wall. Researchers then linked the data of valleys connected to a crater breach. They found that valleys were formed away from craters while craters took shape when lakes were flooded. Researchers said that the findings give hope to human efforts to find a source of water on Mars.

Water is an essential element for life to habitat. The findings are also an indication that the Red Planet hosted life. Scientists are already searching for possible signs of microbial life on the planet. Mars today has no water in the liquid form on its surface. Studies of Martian meteorites almost four decades ago established that Earth’s neighbor was once water-rich. But the planet was dried up due to continuous climate change. The Martian atmosphere is very thin today and most composed of CO2. NASA’s missions have sent several photos of Martian landscapes. These images have been marked by river valleys and flood channels.
