First sounds of wind on Mars captured by InSight spacecraft

  • 20 second audio clip shows sound of wind on Mars
  • Clip also supports evidence of wind speed and direction on Mars

DUBAI: An audio clip of the first sounds captured on Mars by its latest inhabitant, the InSight probe, was released last week, British broadcaster BBC reported.

The clip, 20 seconds long, has captured the sound of the wind on the desert planet.

InSight carries a British-made seismometer package, which was able to detect the vibrations from Martian air rushing over the solar panels.

Professor Tom Pike, leading the seismometer experiment from Imperial College London, likened the placement of the solar panels to the robot “cupping its ears”. “[They are] the perfect acoustic receivers.” he said.

The wind on Mars moves from the northeast to the southeast at about five to seven meters per second, according to the latest estimates. This falls in line with evidence shown by satellite pictures that display the tracks left by dust devils travelling in the same direction.

 “This is brilliant news because it means we know the sensors have survived the rigors of landing on Mars and are meeting the requirements to achieve their science goals,” Sue Horne, head of space exploration at the UK Space Agency, told the BBC.

“It is just amazing to hear the first ever sounds from Mars,” Horne added.

InSight landed on Mars on November 26th, following a six-month journey from Earth. Its overall aim is to study the world's interior from the mission site, a flat plain just north of Mars's equator.

Saudi ICT sector holds key to growth, forum told

  • 5G will be used in 30% of big cities in Saudi Arabia by 2020
  • 90% of KSA has 4G technology coverage, including remote centers and villages

RIYADH: Information and communications technology (ICT) is one of the main drivers of development in today’s world, a Riyadh forum on “Digital Transformation for an Ambitious Country” has been told.

In his opening speech to the annual Communications and Information Technology Indicators Forum, Abdul Aziz Al-Ruwais, governor of the Communications and Information Technology Commission, said the ICT sector stimulated productivity, enhanced competitiveness and encouraged innovation.

On Wednesday, the Saudi minister of communications and information technology, Abdullah bin Amer Al-Sawaha, joined regional and global leaders in the ICT sector, telecom executives and government officials at the forum.

Al-Ruwais said that ICT has been used to “develop strategies and regulatory policies that can guarantee the availability of infrastructure, basic apparatus and services in all regions of the Kingdom.”

“In order to facilitate the mission of researchers, experts and those interested in telecommunication services indicators, the Communications and Information Technology Commission established an electronic platform that allows the user to have access to indicators and statistics related to the sector. This platform enables the user to view the indicators in the form of tables and detailed graphs,” he said.

Al-Ruwais said the commission has achieved 90 percent coverage of 4G technologies in the Kingdom, including remote centers and villages.

He said the authority has issued temporary licenses for fifth-generation networks, equipping 153 sites with 5G in nine cities. So far, 680 trials were conducted for 5G.

He said that ICT services achieved high indicators during the 2017 Hajj season, with local and international calls totaling 439 million through 16,000 base stations.

Mufarreh Nahari, director of Market Studies at CITC, said: “It is expected that by 2020 the experimental uses of 5G will be fully completed and they will be ready to launch the official 5G sim by then. By the end of 2020 we expect that 5G will be used in 30 percent of the big cities in Saudi Arabia.”

The past three years have seen an increase in internet usage. In 2018, two-thirds of Internet users in the Kingdom used the internet for more than four hours a day, said Nahari.

Ammar Al-Ansari, department head of Country Digital Acceleration at Cisco, said: “The agreements signed by the crown prince during his overseas visits led to the introduction of a number of artificial intelligence (AI) techniques, including virtual schools and smart classrooms.” 

Seven schools in Saudi have a live stream for teachers to connect with their students. They may be 250 km to 300 km apart, but an active learning session takes place between students and educators.

Al-Ansari displayed a video from a teacher in Jeddah giving lessons to students in the northern region via a smart board. AI was used to monitor and analyze students’ attention spans. 

The analysis will help educators update traditional teaching methods.
