What does the seven minutes of terror refer to?
In Mars missions, the ‘seven minutes of terror’ is actually referred to the entry, descent and landing (EDL) phase of the rover as the events take place much quicker than the radio signals can reach Earth from Mars for communication. The Perseverance rover will get into its landing phase starting at 3:48 PM EST.
What happened to Curiosity Skycrane?
With Curiosity dangling 20 feet below, Sky Crane continues its downward progress until the rover is resting on the surface. Explosive bolts cut Curiosity’s last physical attachments to the outside world, and Sky Crane flies away to death-plunge into the red sands, its incredible job done.
What are the four scientific goals of the MSL?
The mission’s primary objectives are to assess the biological potential of the landing site, characterize the geology of the landing region, investigate planetary processes that influence habitability, and characterize the broad spectrum of surface radiation.
