Amazing camera technique reveals hidden secrets of Sun’s atmosphere



Researchers behind a Sun-noticing test applied a straightforward hack to one of its cameras, permitting them to look into seldom seen locales of the Sun’s air.

The mission’s scientific team was able to capture a portion of the Sun’s atmosphere at extreme ultraviolet wavelengths with the help of Solar Orbiter’s Extreme Ultraviolet Imager (EUI). The somewhat late change to the instrument included adding a little, jutting “thumb” to hinder the splendid light coming from the Sun to such an extent that the fainter light of its climate could be made noticeable.

“It was really a hack,” Frédéric Auchère, an astrophysicist at the Institute of Astrophysics of the Université Paris-Sud in France, and a member of the EUI team, said in a statement. “I had the idea to just do it and see if it would work. It is actually a very simple modification to the instrument.”

The structures in the Sun’s atmosphere are captured in high resolution by EUI. EUI’s team added a thumb to a safety door that slides out of the way to let light into the camera and allow it to take pictures of the Sun. However, if the door stops halfway, the thumb ends up blocking the bright light from the Sun’s central disc in order to let the fainter ultraviolet light from the corona (the atmosphere’s outermost layer) through.

The outcome is a bright picture of the Sun’s crown. According to ESA, the thumb hack has left a blank area in which an ultraviolet image of the Sun’s disc has been superimposed in the middle.

The crown is generally concealed by the brilliant light of the Sun’s surface, and can for the most part be seen during an all out sun oriented obscure. By obstructing the Sun’s light, the camera hack somewhat resembles the eclipse. Scientists have long been baffled by the Sun’s corona, which reaches temperatures of 1.8 million degrees Fahrenheit (1 million degrees Celsius) and is significantly hotter than the Sun’s surface.

Daniel Müller, ESA’s Project Scientist for Solar Orbiter, stated in a statement, “We’ve shown that this works so well that you can now consider a new type of instrument that can do both imaging of the Sun and the corona around it,”

ESA’s Sun powered Orbiter sent off in 2020 determined to catch pictures of the Sun at a nearer distance than some other shuttle and utilizing six instruments to unwind a portion of the star’s secrets.


Fans Of Starfield Have Found A Halo Easter Egg




Starfield has a totally huge world to investigate, so it was inevitable before players began finding Hidden little goodies and unpretentious gestures to other science fiction establishments that preceded it. As of late, a specific tenable planet in the Eridani framework has fans persuaded it’s a diversion of a fairly sad world in the Corona series.

Players have found that Starfield’s rendition of the Epsilon Eridani star framework, a genuine star framework that is likewise a significant piece of Corona legend, incorporates a planet that looks similar to that of Reach, where 2010’s Radiance: Reach occurred. Portrayed on Halopedia as including “transcending mountains, deserts, and climate beaten timberlands,” Starfield’s Eridani II has comparative landscape to Reach. Unfortunately, nobody’s found any unusual ostrich-like birdies.

As referenced, Eridani II is a genuine star framework out there in the void. It was first expounded on in Ptolemy’s Inventory of Stars, which recorded north of 1,000 universes, as well as other Islamic works of cosmology. During the 1900s, being around 10.5 light-years from our planetary group was assessed. Epsilon Eridani and Tau Ceti—also featured in Starfield and Marathon, another Bungie shooter—were initially viewed by SETI (the Search for Extraterrestrial Intelligence project, which searches the skies for signs of other civilizations) as a likely location for habitable planets that either contained extraterrestrial life or might be a good candidate for future space travel.

Assuming that you might want to visit Eridani II in Starfield, you can do so from the beginning in the game. Beginning from Alpha Centauri (home of The Hotel and other early story minutes in Starfield), go down and to one side on the star guide and you’ll find the Eridani star framework, which is just a simple 19.11 light years away.

Navigate to Eridani II and land in any of its biome regions for pleasant weather and mountainous terrain once you’re there. As certain fans have called attention to, Eridani II’s areas are nearer to what’s found in the Corona: Arrive at level “Tip of the Lance” than its more rich, lush regions displayed in different places of the game’s mission. This is an ideal place for Radiance fans to fabricate their most memorable station (and you will not need to manage the difficulties of outrageous conditions).

The preparations made by NASA to collect an asteroid sample that landed in the desert




After nearly 2 years in space, a NASA spacecraft carrying an asteroid sample is about to reach Earth.

NASA is collecting and returning an asteroid sample from space for the very first time.

The rocks and soil, along with a sample of the asteroid Ryugu from Japan’s Hayabusa2 mission, may provide clues about how our solar system started.

The OSIRIS-REx mission will drop the sample of rocks and soil and continue its journey to study another asteroid rather than landing.

Teams have been practicing how to retrieve the sample on September 24, when it will drop into the Utah desert, which was originally obtained from the near-Earth asteroid Bennu.

It is assessed that OSIRIS-REx gathered up to 8.8 ounces, or around 1 cup, of material from Bennu.

In a statement, Nicola Fox, associate administrator of NASA’s Science Mission Directorate, said, “This successful drop test ensures we’re ready.” “We are now just weeks away from receiving a piece of solar system history on Earth.” Perfect material from space rock Bennu will assist with revealing insight into the arrangement of our planetary group 4.5 quite a while back, and maybe even on how life on Earth started.”

It doesn’t happen very often that a spacecraft launches a capsule above the planet with the intention of safely transporting a unique sample of an asteroid to a specific landing site.

Long periods of difficult work by great many individuals have prompted the second when the Bennu test shows up on The planet.

Teams practiced recovering the sample capsule and ran through all possible outcomes, both positive and negative, prior to reentry day in the spring and summer.

The initial objective of the mission was to obtain a flawless asteroid sample. Be that as it may, on the off chance that the container crash-terrains and opens up, the example could become defiled.

“I’m massively pleased with the endeavors our group has filled this undertaking,” said Dante Lauretta, head specialist for OSIRIS-REx at the College of Arizona in Tucson, in a proclamation. ” We have honed our skills for sample recovery in the same way that our meticulous planning and practice helped us get ready to collect a sample from Bennu.

The first return mission for an asteroid sample is OSIRIS-REx, which stands for Origins, Spectral Interpretation, Resource Identification, Security, and Regolith Explorer. The journey of the spacecraft has lasted seven years. After launching in 2016, OSIRIS-REx entered Bennu’s orbit in 2018, collected the sample in 2020, and embarked on its extended return journey to Earth in May 2021.

Since leaving Bennu, the space apparatus has orbited the sun two times so it tends to be on the right direction to meet with Earth.

The mission team sent a series of maneuvers to the spacecraft in July to help it find a place outside of Salt Lake City where the capsule could land at the Department of Defense’s Utah Test and Training Range.

NASA will provide a live stream of the sample’s arrival on Earth on September 24. The live stream will start at 10 a.m. ET, and the container containing the example will enter Earth’s environment at 10:42 a.m. ET, going around 27,650 miles each hour (44,498 kilometers each hour).

Four hours before the container’s air passage, the mission group will choose whether to send an order to the rocket to deliver the case, said Rich Consumes, OSIRIS-REx project director at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

The decision is based on the trajectory of the spacecraft, which determines the capsule’s ability to survive the angle, the temperature of reentry, the accuracy of the landing, and the safety of humans within the landing zone. Burns stated that the point at which OSIRIS-REx will be 63,000 miles (102,000 kilometers) from Earth and heading for an area that spans 250 square miles (647.5 kilometers) is when the capsule will be released. According to Burns, this will be “the equivalent of throwing a dart across the length of a basketball court and hitting the bull’s-eye.”

Burns stated that OSIRIS-REx will conduct a divert maneuver once the capsule is released, putting it on a course around the sun and aiming for Apophis, another asteroid, in 2029 for a rendezvous.

The capsule will be enveloped by a superhot ball of fire when it enters Earth’s atmosphere, but the sample inside will be protected by the container’s heat shield.

Sandra Freund, OSIRIS-REx program manager at Lockheed Martin Space, which partnered with NASA to build the spacecraft, provide flight operations, and help recover the capsule, stated that parachutes will deploy to slow the capsule down for a gentle touchdown at 11 miles per hour (17.7 kilometers per hour). Recovery teams will be standing by to retrieve the capsule once it is safe to do so.

13 minutes after the capsule enters the atmosphere of Earth, landing is anticipated.

The sample will be transported to a temporary cleanroom at the range in June by helicopter in a cargo net. The sample container will be prepared there by a team before being flown on a C-17 aircraft on September 25 to NASA’s Johnson Space Center in Houston. On October 11, a NASA broadcast hosted by Johnson will provide the public with information regarding the sample.

Training in the desert, according to Freund, NASA and Lockheed Martin Space teams have practiced every possible step in preparation for delivery day.

A sample capsule was recently dropped, collected, and prepared for transport by the team using an airplane.

It also dealt with difficult scenarios from the command center, such as what to do in the event of a reboot, how to get the spacecraft out of safe mode, and how to move communications between centers in the event of network outages.

The group has likewise arranged for various landing situations, for example, a hard landing where the container containing the example opens startlingly. After that, the team would determine if any of the sample could be saved.

According to Burns, there is also the possibility that the spacecraft will not be able to release the sample on September 24 if landing within range is impractical. In that situation, the example would stay ready, and the space apparatus’ circle would bring the case back by Earth to endeavor one more delivery over Utah in 2025.

The Johnson Space Center has a long history of storing, handling, and analyzing extraterrestrial materials, such as Apollo lunar samples. NASA has dealt with making an exceptional office at Johnson for the Bennu test for a really long time, said Kevin Righter, OSIRIS-REx representative curation lead.

As scientists examine the rocks and soil over the next two years, the dedicated cleanroom will keep any potential cross-contamination with other collections out of the equation. Christopher Snead, OSIRIS-REx deputy curator at Johnson and lead for small-particle handling, says that some of the material will be smaller than a grain of sand.

“We have been developing custom tools to carefully handle these precious particles within our new gloveboxes,” Snead said in a statement, referring to the boxes for managing hazardous or extraterrestrial material.

The example will uncover data about the arrangement and history of our planetary group as well as the job of space rocks in creating livable planets like Earth. Bennu and other asteroids are thought to have delivered elements like water to Earth early in their formation.

The sample will be divided up and sent to laboratories all over the world, including the Canadian Space Agency and the Japanese Aerospace Exploration Agency, which are OSIRIS-REx mission partners. Around 70% of the example will stay flawless away so people in the future with better innovation can learn considerably more than whatever’s presently conceivable.

“The asteroids that we have in our solar system today are left over from the earliest stage of solar system history,” Lauretta said. “We’re literally looking at geologic materials that formed before the Earth even existed. I call these the grandfather rocks, the ones that really represent our origins and where we came from. This is a gift to the world.”

Making Oxygen on Mars: NASA’s MOXIE’s Victory




The descendants of a microwave oven-sized device may be to thank when the first astronauts land on Mars for the air they breathe and the rocket propellant that gets them home.

On NASA’s Perseverance rover, this apparatus, known as MOXIE (Mars Oxygen In-Situ Resource Utilization Experiment), has produced oxygen for the 16th and final time. After the instrument demonstrated definitely more effective than its makers at the Massachusetts Establishment of Innovation (MIT) expected, its activities are closing.

NASA Deputy Administrator Pam Melroy stated, “MOXIE’s impressive performance shows that it is possible to extract oxygen from Mars’ atmosphere.” Oxygen could aid in the supply of breathable air or rocket propellant for future astronauts. It is essential to develop technologies that enable us to utilize resources on Mars and the Moon in order to establish a robust lunar economy, support a first human exploration mission to Mars, and establish a long-term lunar presence.

MOXIE has produced a total of 122 grams of oxygen since Perseverance landed on Mars in 2021, or about what a small dog breathes in ten hours. MOXIE was able to produce 12 grams of oxygen per hour at 98% purity or better at its highest efficiency, which was twice as much as NASA’s initial goals for the instrument.

On August 7, during its 16th run, the instrument produced 9.8 grams of oxygen. During a full year on Mars, MOXIE met all of its technical requirements and was used in a variety of conditions, allowing the instrument’s creators to learn a lot about technology.

Innovative Technology for Future Explorations

“We’re proud to have supported a breakthrough technology like MOXIE that could turn local resources into useful products for future exploration missions,” said Trudy Kortes, director of technology demonstrations, Space Technology Mission Directorate (STMD) at NASA Headquarters in Washington, which funds the MOXIE demonstration. “By proving this technology in real-world conditions, we’ve come one step closer to a future in which astronauts ‘live off the land’ on the Red Planet.”

MOXIE uses an electrochemical process to separate one oxygen atom from each molecule of carbon dioxide pumped in from Mars’ thin atmosphere to produce molecular oxygen. Analyses are performed on these gases as they move through the system to determine the quantity and purity of the oxygen produced.

Pioneering Use of Martian Resources

While many of Perseverance’s experiments are addressing the primary scientific objectives of the mission, MOXIE was focused on human exploration in the future. The first demonstration of technology that humans could use to both live on and leave the Red Planet was MOXIE. Future missions might benefit from an oxygen-producing system in a number of ways, the most significant of which would be as a source of rocket propellant, which astronauts would need in large quantities to launch rockets with on their way back home.

As opposed to carrying enormous amounts of oxygen with them to Mars, future space explorers could live off the land, utilizing materials they find in the world’s surface to make due. In-situ resource utilization, or ISRU, is a concept that has developed into a growing field of study.

“MOXIE has clearly served as inspiration to the ISRU community,” said the instrument’s principal investigator, Michael Hecht of MIT. “It showed NASA is willing to invest in these kinds of future technologies. And it has been a flagship that has influenced the exciting industry of space resources.”

Future Focus

Even though Hecht and his team have learned a lot about how to design a version of the instrument that is more efficient, building MOXIE 2.0 would not be the next step. Rather, it is make a full-scale framework that incorporates an oxygen generator like Spunk and a method for melting and store that oxygen.

But more than anything, Hecht would like to see other technologies get their turn on Mars. “We have to make decisions about which things need to be validated on Mars,” Hecht said. “I think there are many technologies on that list; I’m very pleased MOXIE was first.”

More About the Mission

A critical goal for Diligence’s central goal on Mars is astrobiology, including the quest for indications of old microbial life. The rover will describe the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and collect and store Martian rock and regolith (broken rock and dust) for the first time.

Together with the European Space Agency (ESA), subsequent missions of NASA would send spacecraft to Mars to retrieve these sealed samples from the surface and bring them back to Earth for in-depth analysis.

The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration strategy, which also includes Artemis missions to the Moon to help prepare humans for Mars exploration.

The Perseverance rover is built and operated by NASA’s Jet Propulsion Laboratory, which is managed by Caltech in Pasadena, California, for the agency.

JPL deals with the Pizazz project for the Innovation Exhibition Missions program inside STMD. The Science Mission Directorate and the Exploration Systems Development Mission Directorate of NASA provided additional assistance to MOXIE.
