Mars Insight Lander Hits a Snag

Recommended Posts

Posted (edited)

The Insight lander on Mars is bent on boring into the Red Planet to study its heat flow. Unfortunately, it struck something hard at a depth of only 18 centimeters, presumably rocks. That sounds about like my back garden!

The plan now is to let Insight rest for a bit, then try again. The hammering action of Insight's borer is supposed to break through rocks of reasonable size, so perseverance may yet further. They hope to eventually reach a depth of nearly five meters. 

Below, please find a link to an article with more particulars:

It seems that Insight finally got past the first rock at 18 centimeters, but then found another at about 50. Instead of a couple of days pause for equipment cooling and temperature measurements, as planned, they now want to to wait about two weeks, while they consider the situation, and how to proceed. That second rock must have caused them a good deal of trouble.

Below, please find a link to an article with further information.

NASA has worked out a plan to determine what went wrong with the Insight Lander's heat-measuring instrument, which was intended to eventually penetrate up 5 meters below the Martian surface. It became stuck at only about 10 percent of its goal. They suspect one of three things happened. 

1.) The heat probe struck a rock it has not been able to dislodge with its hammering action.

2.) An unexpected layer of gravel was encountered, stopping its progress.

3.) The mechanism on board the lander that pays out the cable behind the heat probe is jammed.

They will try brief, 15-minute-long sessions of hammering, while scrutinizing the cable mechanism with the onboard camera. They will also  listen with its seismograph to see if this can reveal the nature of any obstruction.

Please find an article linked below, with further details on the Insight Lander's current predicament:

I don't know what the big deal is, if they dig up a martian worm, they will then proceed to tell the world that they found a curious rock that resembles a worm, and the next day a martian worm that looks like a rock that moves!

Which can be easily explained away as strong winds,....ok, not that one, rain,....no,...um,.....on a hill, an earthquake, asteriod hit closeby, Harry Potter was in the general area, that will do.
