Scientists Remember the Mars Rover Opportunity as Hope Fades for Its Resurrection

A massive brutal dust storm came into Mars last summer. The disaster around the planet sprayed on the brush Nuclear powered Inquiries, but the rover closed Good solar power down as the thick sun dust light from Sun. The opportunity remained still from June 10, 2018, despite hundreds of NASA's attempts to contact. When Mars started a wind season in November, scientists expected that litter could be clear from its solar panels, but this hope seems to be still. NASA continues to send rehabilitation orders, but sadly, it seems that the Opportunity mission ends.

At the same time, 2019 gives a milestone of work, which officially left its 15th year on Mars on January 25th This is far beyond the expected 90-day lifespan . In addition to the spiritual spirit, which ended in 2010, the Mars Exploration Rover (MER) mission is one of the most important scientific programs in the modern era, and evidence of Mars being fluid-covered and sending images of images back of the surface of the planet.

Oppy's 15th birthday, and with the knowledge that we can not hear again from the heart again, we ask scientists from the MER mission and elsewhere to share their thoughts and memories Some on Opportunity, Spirit and their heritage. [19659005] Steve Squyres prime investigator Mars Exploration Rover Mission (MER) and professor at Cornell University:

I still did not get up. There is a list of things we have tried, and we do not until we try to do everything. But we're going towards the bottom of the list, so it's an appropriate time to start thinking about these things. As long as he feels, he feels good … He is honorable. [The rovers] without death. You know you're going to lose them sooner or later. To spend a 90-day mission for 15 years, and then one of the most vibrant dust storms that Mars has hit for a very long time, we can walk out so that our heads will be high.

The legacy is tough … The heritage and heritage of both Sprit and Opportunity, and the spirit and legacy of the staff that were built in the first place, is the heritage. team of engineers, scientists, managers, leaders and financial people. The reason why they have been successful is 15 years ago. That's where the credit belongs.

On the scientific heritage, Mars successfully became a much more interesting place than I expected. It changed the way people look at Mars. We have had the three prior tensions on these flat materials, because of that – as the safest places to make land. That's the whole land we've seen. That is what I found so exciting about making a mission. The rovers are a bit of sight to climb mountains and reach the skin. Mars is truly beautiful, beautiful and interesting in the sense that you can imagine that you are there and walking in the tracks of the margins and that they can see what they can see. That changes our perspective.

The third part of the heritage is the effect of these missions on the children. One of my favorable dreams, and I know that this has probably happened, was the age of 8 years of age watching the television in 2004 the night we came to a land and thought, "Whoa, I think it's cool but I can do better." I see that there is evidence that the mission has done to a certain extent, encouraging young people to pursue professions in science, engineering and technology with their own dreams.

Kirsten Siebach planetary guy, Rice University:

The rovers are the rollers. They had a huge impact. After Mars has opportunities, we have new images from another planet surface since I was in high school. Spread our understanding of Mars, and I feel that a level of dependency is always being maintained. It's a motivation for those who work on Mars, for students, and to anyone in the community thereafter. It makes it accessible and close to Mars … In my opinion, the heritage is important to the idea of ​​exploration, and generation is encouraged to think that we are so close to other phones, and that we continue to explore the Solar System and learn modern things every day …

Everyone talked about great engineering that allows us to drive a robot on another planet without a mechanic in absurd conditions for 15 years. That is a wonderful surprise. But for me and the people on the team, there are all those 15 years. There were people here on the Earth on a science and engineering team meeting three or five times a week addressing the progress from the previous day, and that the next day's Opportunities would be carefully registered . With regards to that team, it's no more than a robot but we have to miss it … It was really fun working on it, we are delighted that it was so successful. And that level of dust is certainly honorable if we do not keep it back again.

Kevin Lewis assistant professor at Johns Hopkins University:

Hopefully opportunities come back online! I was on the MER team back in the grade school (2003-2009), which will notice how long the mission lasted – 15 years about three Ph.D. Opportunity was doing great science until he lost contact, and exploring rock units that would never be able to find his original design parameters. Both Spirit and Opportunity restored the way in which we do science on Mars, and it is safe to say that we will not have a great success in the MER mission. Spirit and Opportunity * is still in the future for the sake of curiosity and future climbers throughout the Solar System, through its unique technical and scientific achievements.

Tanya Harrison planetary spokesman and Research Director at Arizona State University Space Technology and Science Initiative, and Mars Exploration Rover Opportunity's scientific team co-operative:

Easily give us any chance of your potential. She admitted mysterious the hematite signal that was received from orbiters before her, and she taught us about underwater conditions and wind on Mars, and disappeared beyond any other rotation over the Earth. No matter how the Red Planet spent her, she and her smart team engineers managed to come around him – to the last global global storm. But it's not just what Oppy has called out is the strongest dust storm ever seen on Mars. Now she can relax, knowing that humanity was proud of our little robotic emissary.

Ashwin Vasavada Mars Science Laboratory Laboratory / Rover Project Scientist Inquiry at NASA Jet Jet Lab:

The opportunity of the Superintendent was an inspiration for the announcement of the Rover Curiosity, as it showed how a virtual field geologist could play an ancient story of an ancient piece studying the record that took place in the rocks. Ancient water flows across the surface, sweeps between the curtains, groundwater putting the rocks up, such things are good … I kept all over during the most difficult days of Curiosity to Mars .

Emily Lakdawalla senior editor of The Society Planetary:

Spirit and opportunities really a new path for Public communication on an active scientific mission when Steve Squyres and Jim Bell made the choice of all images available to the public when they came to the Earth. They wanted to ensure that students could work with the data, and it was not a password protected server … Jim and Steve said, "No, we want the public to enjoy the incident in the same way We. "That decision was so spectacular. He created this huge international community of people who were able to explore the everyday dream of another planet through the eyes of Spirit and Opportunity. People want to make mosaics and animations, discuss the rocks they were looking for, and what the scientific team had. In many cases, people in Europe could see the images before the American Squyres team worsened to check these forums because it was easier to deal with [the server].

Cassini's team had no plans to share their images in this way. NAS Jet's Propulsion Lab (JPL) said, when the Mars Exploration Rover mission saw, many of us are also trying to share Cassini images. Many of the other missions played a walk-all missions in the Mars country, such as Curiosity, Phoenix, and InSight. It has an impact on the European Space Agency to be more open with its image data – its structure is different than the NASA structure, since the institutions take the cameras and provide them – but they were able to share a camera called the VMC emits images [from Mars] as soon as they hit the Earth, and Rosetta shares their NavCam images quickly. Juno and New Horizons quickly swapped their data … It has a huge impact on the way the missions are shared their data to the public.

I think it's very interesting, when Opportunity first came, that many people were ready to write it right away. This might be more practical, but it did not take into account the feeling of people waiting for this spacecraft for a long time. I think it is necessary for all staff to skip all the way they can get some closure to the mission. Some of them are not sure they want to give up … It builds huge emotional investment to keep these missions. Guess, I hope that Opportunities make us surprise and come back. I'm thinking that it is unlikely, and I'm sorry that the engineers are due to their loss. People need to spend time, and realize that it is emotionally difficult.

Abby Fraeman Rover deputy spokeswoman at NASA Jet Laboratory:

regularly interacting with the team. These people have been working for this mission for a long time, and while people left and others have come in, this wonderful sense of friendship is. I can identify everyone by voice. I know that we can rely on people when we face difficult challenges or scientific issues. It's really fun working all these problems with the people involved. I'll lose every morning and I'll see what the rover has got down, what are the newest pictures. Every day you get something that never seems ever before.

I have a very personal story with the rover. I was in high school when Spirit and Opportunity came into a land. The Planetary Society, which is known as the Student Astronaut Program, was running a program, which many students left to JPL for the night the crannon came into. I was in the night that Opportunity was in a country, and that it was a great experience that inspired me to enter into planet science.

The Mars transformation of both Science and Opportunity was both the way and gave us a new perspective on the planet we did not have in 2000. The rovers were asked to follow the water, and before we did not have any positive evidence that Mars had ever had liquid water in the past. This was the first images from Oppy, and later images from the Spirit, which had unintentional evidence that Mars had a different climate that could support liquid water on the surface. It opened a new new parameter space for questions that we might ask about the evolution of Martian. These questions were answered by the Investigating rover, a newer rover with more sophisticated instruments, and some of the missions will answer some examples; it will be necessary to answer other missions. We did not know what questions we will ask before we get the results from Spirit and Opportunity.

I'm just glad to have been killed as long as it was. It is a celebration of how this mission was successful and intrinsic.
