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.


Russian scientists find defect in new heavy lift space rocket engine

Russian scientists find defect in new heavy lift space rocket engine

  • The new heavy lift space rocket is capable of carrying more than 20 tons into the orbit
  • Russian President Vladimir Putin said the project is very important for the country's defense

MOSCOW: Scientists have discovered a defect in the engines of Russia’s new flagship heavy lift space rocket that could destroy it in flight, an apparent setback to a project President Vladimir Putin has said is vital for national security.
The Angara A5, which was test-launched in 2014, is being developed to replace the Proton M as Russia’s heavy lift rocket, capable of carrying payloads bigger than 20 tons into orbit. A launch pad for the new rocket is due to open in 2021.
In July, Putin said the Angara A5 had “huge significance” for the country’s defense and called on space agency Roscosmos to work more actively on it and to meet all its deadlines.
The issue with the Angara A5 was brought to attention by scientists at rocket engine manufacturer Energomash in a paper ahead of a space conference later this month.
The paper, reported by RIA news agency on Friday and published online, said the engines of the Angara A5 could produce low frequency oscillations that could ultimately destroy the rocket.
A special valve had been fitted to mitigate the issue, but in some cases the oscillations continued, it said. Energomash did not immediately reply to a request for comment.
Russia’s space program has been dogged by mishaps in recent years, including failed cargo delivery missions into space and the aborted launch in October of the manned Soyuz mission to the International Space Station. Russia’s current heavy lift rocket, the Proton M, has had a nearly 10 percent failure rate in more than 100 launches since it entered service in 2001, creating pressure to reorganize and improve the space program.
