Portuguese explorer wins award for artificial intelligence tool for exploring exoplanets - DNOTICIAS.PT

The creation of an artificial intelligence tool that allows highly accurate data collection on exoplanets, which contributed to the implementation of the mission of the European Space Agency, won the researcher Louis Simoins in the Ariel Machine Learning Data Challenge.

The award was presented after Louis Simoins improved his ability to detect exoplanets by capturing the light emitted from a star using a highly accurate algorithm.

The task was launched by the European Space Agency (ESA) to provide the necessary conditions for the study of exoplanets (planets that orbit a star but do not belong to the solar system) in the Ariel mission, which will be launched in 2029. …

For the Portuguese researcher who “occasionally competes in machine learning for space,” the competition had the advantage of developing his “ability to solve problems and apply different algorithms” and keep abreast of developments in artificial intelligence. “.

To a problem that he considered “excellent because of its relevance and complexity,” he answered by creating a solution with an average error of 0.00007.

“The specific task – the detection of exoplanets – is solved by different approaches, but the one that turned out to be more successful is associated with the study of light curves, therefore, the light that comes to us from the star, and when the planet passes forward in its orbit, the shape that takes this curve tells us a lot about the planet, ”explained Luis Simoes to Luce.

He admits that this method has already been used to “identify thousands of exoplanets,” “but this mission has a very ambitious goal,” which includes “understanding the chemical composition of the atmospheres of these planets.”

“It will only be possible with tools that are not there today, hence the interest, 10 years ago, to start learning and challenge the community,” added Luis Simoins.

The solution he came up with does not provide any new data, but Luis Simoins created “a model, almost error-free (…) high-precision model.”

This accuracy matters, because “the question of the chemical composition of the atmosphere is the subsequent processing of the data that the algorithm will give.”

“There he already enters into other areas of astrophysics, but the fact is that if an incorrect interpretation is made at this stage of the data interpretation chain, then the next steps will be misled as to what the real characteristics of the planet will be.”, Materialized.

For this, the algorithm is programmed “automatically based on the training data”.

To this end, the team leading the ESA mission “has created synthetic data using simulators that recreate with maximum accuracy at the moment what data the mission will collect in the future.”

This data was distorted “due to data distortions that may arise during the mission – due to thermal fluctuations, due to the whole problem of measuring hundreds of light years, how many photons are coming from different sources”, but knowing what the original data was , it was possible to assess the degree of accuracy of the presented solutions.

“We are several years away, this is not the final model, but it is already a significant step towards achieving the levels of accuracy that the mission wants to have,” the researcher said.

Luis Simoins began working on the use of artificial intelligence for solving space problems, creating “systems for Airbus and ESA to control the landing of ships on other planets.”

In 2008, due to the crisis, he moved to the Netherlands, where he began to cooperate with the ESA.

He returned to Portugal in 2018, where he founded ML Analytics with his wife.

‘My power is really low’: NASA’s Mars Insight rover prepares to launch from the Red Planet

Published

on

NASA Lander InSight He has delivered what may be his last message from Mars as he embarks on a historic mission to uncover the secrets of the Red Planet’s interior.

In November, the space agency warned that the probe could be running out of time as dust continued to condense and stifle InSight’s power.

“Spacecraft power generation continues to decline as windblown dust accumulates on solar panels,” NASA said in a statement. Update November 2. “The end is expected to come in the coming weeks.”

message shared NASA The InSight Twitter account tweeted on Monday: “My power is very low so this might be the last photo I can upload. Don’t worry about me: my time here has been productive and uneventful. If I can keep talking to my mission team, I will—but I will.” Subscribe here soon. Thank you for staying with me.”

A geologist robot armed with a hammer and a seismograph first reached the barren expanse of Elysium Planitia in November 2018.

Since then, she has carried out geological excavations, taking the first measurements of earthquakes with a high-tech seismometer placed right on the surface of Mars.

Last month, the solar-powered car released an update to remind us of its time in space.

“I was lucky to live on two planets. Four years ago I made it safely to the second one, much to the joy of my family at first. Thanks to my team for taking me on this journey of discovery. I hope I can be proud of you.”

According to the published mission, Insight has measured more than 1,300 seismic events since it was published, and more than 50 of them had signals clear enough for the team to extract information about their location on Mars. Results.

The probe’s data also provided detailed information about Mars’ interior, liquid core, surprisingly variable remnants beneath the surface of an extinct magnetic field, climate and seismic activity.

old for Its launch in 2018NASA Chief Scientist Jim Green said the mission was “fundamental to understanding the origins of our solar system and how it became what it is today.”

NASA will not declare the mission complete until Insight confirms the arrival of two spacecraft orbiting Mars that are relaying their information back to Earth.

In 2018, the veteran rover announced the capabilities end of his 15 year stay Sending an incomplete photo of the Valley of Perseverance.

A severe dust storm darkened the sky around the solar-powered rover, shattering the sun and leaving behind a dark image with white spots due to camera noise. The transmission is interrupted before the complete image can be transmitted.
