Nasa lan­der cap­tures first sound of Mars wind

Irish Examiner - - World News - Mar­cia Dunn

Nasa’s new Mars lan­der has cap­tured the first sounds of the Mar­tian wind.

The Jet Propul­sion Lab­o­ra­tory re­leased au­dio clips of the alien wind, which is es­ti­mated to be blow­ing be­tween 10mph to 15mph.

The low-fre­quency rum­blings were col­lected by the In­Sight lan­der dur­ing its first week of op­er­a­tions on Mars.

These are the first sounds from Mars that are de­tectable by hu­man ears, ac­cord­ing to the re­searchers.

“Re­minds me of sit­ting out­side on a windy sum­mer af­ter­noon ... In some sense, this is what it would sound like if you were sit­ting on the In­Sight lan­der on Mars,” Cor­nell Univer­sity’ s Don Ban­field told re­porters.

The noise is of the wind blow­ing against In­Sight’s so­lar pan­els and the re­sult­ing vi­bra­tion of the en­tire space­craft.

The sounds were recorded by an air pres­sure sen­sor in­side the lan­der that is part of a weather sta­tion, as well as the seis­mome­ter on the deck of the space­craft.

The low fre­quen­cies are a re­sult of Mars’ thin air den­sity and even more so the seis­mome­ter it­self.

The seis­mome­ter will be moved to the Mar­tian sur­face in the com­ing weeks; un­til then, the team plans to record more wind noise.
