Next week, Nasa hopes to navigate its InSight spacecraft through the Martian atmosphere. The lander will have to decelerate from 1,300mph to just 5mph in a little under 7 minutes.
InSight was launched on May 5th and should touch down on Monday at 7.35pm Greenwich Mean Time.
The mission is to study the planet's interior for the first time. "Landing on Mars is hard," said Thomas Zurbuchen, associate administrator for Nasa's science mission directorate. "It takes skill, focus and years of preparation" he said. "Keeping in mind our ambitious goal to eventually send humans to the surface of the moon and then on to Mars, I know that our incredible science and engineering team - the only in the world to have successfully landed spacecraft on the Martian surface - will do everything they can to successfully land InSight on the Red Planet."

I think Insight's initial approach speed will be closer to 13,000 mph than 1300 mph?
Insight is also accompanied by two small cubesats "wall-E" and "Eva" which will monitor the descent and then act as communication relays

Saw this posted elsewhere :) Ideal for youngsters, amusing nevertheless.

Comic-strip about the Insight mission (doesn't mention Wall-E and Eva though):

You are quite right about the InSight entry velocity Brian. I did know the correct speed, but I seem to have missed out on striking a key :wink: .

Good to see Insight landed safely, and that Wall-E and Eva performed well :D
