NASA effectively collected a sample from asteroid Bennu, yet some of it is leaking into space

Published

The notable collection of an sample from the close Earth asteroid Bennu by NASA’s OSIRIS-REx shuttle on Tuesday was excessively effective.

A portion of the sample is spilling into space, as per Dante Lauretta, OSIRIS-REx head specialist at the University of Arizona in Tucson during a NASA question and answer session Friday.

“The big concern now is that particles are escaping because we’re almost a victim of our own success,” he said. “Large particles left the flap open. Particles are diffusing out into space. They aren’t moving fast, but nonetheless, it’s valuable scientific material.”

The mission group investigated pictures Thursday taken of the gatherer top of the shuttle that indicated that a considerable example was gathered – however there is such a great amount of material in the head that the fold intended to keep the example inside is stuck.

This is permitting particles to escape into space. The mission group is changing the course of the functions got ready for the shuttle this end of the week and wanting to stow the example as fast as conceivable so minimal material is lost. The scientists assessed that it’s ceaselessly losing between 5 to 10 grams of material. This flaky material buoys in what looks like a haze of particles around the head.

Yet, the group isn’t certain of the specific misfortune rate since it’s not consistent.

The mission was needed to gather at any rate 2 ounces, or 60 grams, of the space rock’s surface material. In light of the pictures they dissected, the analysts are sure that the gatherer head on the finish of the shuttle’s mechanical arm really caught 400 grams of material. What’s more, that is just what’s noticeable to them through the viewpoint of the camera.

In any case, particles are getting away through little holes where a Mylar fold, or top, is being held open by in any event a centimeter by enormous rocks. What’s more, the exercises got ready for the shuttle this end of the week could cause more example misfortune because of development.

Already, OSIRIS-Rex was required to direct a slowing down consume on Friday and an estimation of the example’s mass on Saturday. In spite of the fact that this implies the group won’t have the foggiest idea about the genuine mass of the example until it re-visitations of Earth in 2023, the mission group is certain that it will have an adequate example.

“We are working to keep up with our own success here, and my job is to safely return as large a sample of Bennu as possible,” Lauretta said. “The loss of mass is of concern to me, so I’m strongly encouraging the team to stow this precious sample as quickly as possible.”

The group will experience another assessment cycle this end of the week to guarantee that the example head could be stowed in the example return container by Tuesday to secure free material and guard the valuable freight so it can re-visitation of Earth.

The example head is so full due to how the assortment function surprisingly happened on Tuesday.

The authority head connected during the function Tuesday – to say the very least. Throughout the six seconds when the head landed, it sank 5 centimeters into the space rock’s surface. At the point when the pressurized nitrogen gas bottle terminated, intended to lift up material from the surface, the head sank an extra 24 to 48 centimeters into the surface material.

It is highly unlikely to close the fold, Lauretta said. While the group isn’t certain of the power of the stones holding it open, it must be solid and at as far as possible for what could pass into the assortment head, he said.

This isn’t something the group experienced in their test crusade in front of the mission’s dispatch – which included huge rocks and the example assortment head being covered by the space rock’s surface material. In any case, the scientists didn’t test the example head at the profundity they speculate it really came to on the space rock.

“Bennu continues to surprise us with great science and also throwing a few curveballs,” said Thomas Zurbuchen, NASA’s partner chairman for the science mission directorate at the office’s base camp in Washington.

“Although we may have to move more quickly to stow the sample, it’s not a bad problem to have. We are so excited to see what appears to be an abundant sample that will inspire science for decades beyond this historic moment.”

Notwithstanding when the example is stowed throughout the following week, the shuttle won’t start its excursion back to Earth until March 2021, when the space rock that is as of now 200 million miles from Earth is in arrangement with our planet for a more productive outing home.

The shuttle “stays healthy” to re-visitation of Earth, as per the group.

Starship is Chosen by Lunar Outpost to Transport the Rover to the Moon

Published

on

For NASA’s possible use, Lunar Outpost has chosen SpaceX’s Starship vehicle to transport the Artemis lunar rover it is developing to the moon.

The Denver-based business revealed on November 21 that it has reached a deal with SpaceX to use Starship to deliver the company’s Lunar Outpost Eagle rover to the moon. Neither the launch date nor any other details of the agreement were disclosed by the companies.

In April, NASA awarded contracts to Lunar Outpost and three other firms for the first phase of the Lunar Terrain Vehicle (LTV) program, which will help construct a rover for future Artemis missions. Each business was given a one-year contract to complete a preliminary design review (PDR) of their rovers. The government will then choose at least one of the companies to continue developing the rover.

Delivering the rover to the moon is the responsibility of the firms under the LTV program, which is set up as a services contract. When NASA no longer needs those rovers, those businesses will be allowed to use them for commercial purposes.

In an interview, Lunar Outpost CEO Justin Cyrus stated that the company chose SpaceX after receiving “great responses” from a number of businesses. He stated, “The reason we chose Starship is their technological maturation, the pace at which they move and the quality of that organization “It’s a vehicle that we think will be able to provide reliable landing on the lunar surface, and we know that they can get it done on the timelines we need.”

Although he did not reveal other vehicles his business investigated alongside Starship, Lunar Outpost developed the rover to be compatible with as many conceivable landing mechanisms as possible. “We need this vehicle to be compatible with multiple different lander providers, so that way we have the optionality, that way we have flexibility, and we can evaluate technical progress over time just to make sure we can derisk our commercial case.”

The team working on the rover is led by Lunar Outpost and consists of Leidos, MDA Space, Goodyear, and General Motors. After Lunar Outpost failed to reach a consensus regarding Lockheed Martin’s involvement in the project, Leidos took over as one of the partners on the “Lunar Dawn” team in September.

NASA astronauts recently drove a rover prototype for human factors testing as part of that team’s busy work to improve the rover’s design. Cyrus stated, “We learned what the astronauts really like and what we can improve upon,” 

In roughly six months, the contract’s first phase will come to an end with a PDR. In order to create the rover and acquire services for the following phase, NASA will then ask Lunar Outpost and the other two grantees, Intuitive Machines and Venturi Astrolab, to submit ideas.

Although Cyrus and other industry professionals are urging NASA to select multiple companies to provide redundancy, as the agency has done in other services programs like the Human Landing System, NASA officials have stated that budget constraints mean they are likely to select only one company for that next phase.

“NASA should pick two. Dissimilar redundancy for something this critical, I think, is the right choice,” he stated.

On November 13, Lunar Outpost revealed that it had raised a Series A round, but Cyrus stated that the business would not reveal the size due to competitive considerations. He said that the money would be used to develop the Lunar Outpost Eagle.

Citing commercial interest from potential clients, he noted that the company intends to continue working on the rover even if it is not chosen for the next stage of NASA’s LTV program. Regarding the funding, he stated, “This allows us to accelerate those plans pretty drastically,” “So, no matter what we’re going to be flying this vehicle on Starship.”

NASA and SpaceX Highlight Important Aspects of the Artemis cc

Published

on

As part of its Artemis program, NASA is collaborating with American businesses to create the human landing devices that will securely transport humans from lunar orbit to the Moon’s surface and back.

NASA is collaborating with SpaceX to build the company’s Starship Human Landing System (HLS) for Artemis III, the first crewed lunar landing in more than 50 years. In lunar orbit, Starship HLS would dock with NASA’s Orion spacecraft. Two Artemis crew members will then transition from Orion to Starship and descend to the surface, according to recently revised artist’s conceptual renders. Before returning in Starship to Orion, which is waiting in lunar orbit, the astronauts will gather samples, conduct scientific experiments, and examine the Moon’s environment there. SpaceX will conduct an uncrewed landing demonstration mission on the Moon before the crewed Artemis III mission.

In order to achieve a more comprehensive set of requirements for Artemis IV, NASA is also collaborating with SpaceX to further the development of the company’s Starship lander. These specifications include docking with the agency’s Gateway lunar space station for human transfers and putting greater mass on the moon.

In the artist’s idea, SpaceX’s Starship HLS is shown completing a braking burn before landing on the Moon, with two Raptor engines blazing. In order to lower the lander’s velocity before its final drop to the lunar surface, the burn will take place once Starship HLS leaves low lunar orbit.

NASA will learn how to live and work away from home, explore more of the Moon than ever before, and get ready for future human exploration of Mars with Artemis. NASA’s deep space exploration is built on its SLS (Space Launch System) rocket, exploration ground systems, and Orion spacecraft, as well as its human landing system, next-generation spacesuits, Gateway lunar space station, and upcoming rovers.

Chinese Rover Discovers Signs of Mars’s Ancient Ocean: Study

Published

on

Researchers claim that recently analyzed data from a Chinese investigator on Mars supports the body of evidence showing the planet originally had a massive ocean.

Zhurong is the name of the rover, or exploring vehicle. In 2021, it made its surface landing on Mars. Utopia Planitia is the region where the rover has been functioning. The American space organization NASA says that this region is a sizable plain in the northern hemisphere of Mars.

The scientists integrated information from Zhurong’s equipment with observations from spacecraft and satellites circling Mars. Geological elements that suggested an ancient ocean coastline were found in Utopia Planitia, according to the team’s studies.

Several characteristics, according to the experts, suggested that there was a sizable ocean on Mars billions of years ago. The troughs and channels found on the surface could have been created by water flowing across Mars.

Mud volcanoes, which most likely erupted in regions where there had been water or ice, may have produced them, according to earlier studies that looked at data on comparable surface features.

According to the researchers, the data indicates that both shallow and deep ocean conditions were probably present in the region. The results of a recent study were published in the journal Scientific Reports.

The study was primarily written by Bo Wu. At Hong Kong Polytechnic University, he works as a planetary scientist. According to Wu, “We estimate the flooding of the Utopia Planitia on Mars was approximately 3.68 billion years ago. The ocean surface was likely frozen in a geologically short period.”

On Mars, the hunt for water is closely related to the hunt for potential life. The planet might have once hosted microbial life if there is evidence of a former ocean.

Previous research indicates that Mars formerly had a sizable northern ocean. In 2022, one such study was published. Satellite photos of the Martian surface served as the basis for that study. Detailed maps of the planet’s northern hemisphere were created by combining the pictures. Analyzing the maps revealed indications of coastlines that were previously part of a vast ocean.

Evidence from a different study that was published in August suggested that Mars might have a sizable ocean located far below the surface. NASA’s InSight Lander served as the basis for that proof.

In May 2021, the Zhurong rover from China started gathering data. It ceased operations almost a year later, with mission planners stating that dust and sand probably had an impact on the power system. The rover nevertheless outlived its three-month mission.

According to the researchers, the data indicates that the ocean appears to have vanished approximately 3.42 billion years ago.

According to research co-writer Sergey Krasilnikov, the water that most likely filled the Martian ocean was “heavily silted.” At Hong Kong Polytechnic University, he works as a planetary scientist. Water-borne silt is a mixture of clay and sand that eventually settles on land.

Krasilnikov went on to say that the planet “…probably had a thick, warm atmosphere” when the Martian ocean would have been active.” “Microbial life was much more likely at that time,” he stated.

The latest discoveries do “provide further evidence to support the theory of a Martian ocean,” according to Wu of Hong Kong Polytechnic.

The study does “not claim that our findings definitively prove” that there was an ocean on Mars, he told the French news agency AFP. According to him, such evidence would probably necessitate a further trip to return items from Mars to Earth for additional analysis.
