We don’t fire a rocket motor all the way to mars. We don’t need to You just place the spacecraft on a trajectory to mars and let it coast for seven months and 300 million miles until it reaches the planet Atmospheric entry in 3.. 2.. 1.. Just passed in one minute that atmospheric entry current altitude 121 miles, current velocity 12,084 miles per hour We are now at an altitude of 73 miles moving at a speed of 12,192 miles per hour expected parachute deploy in five seconds four three, two, one, Mark We’re awaiting confirmation parachute has deployed Parachute was detected Heat shield deployed event Spacecraft reporting the scene field at the – Planet separation event has been detected. Spacecraft reporting lander has separated moving at a speed of 173 miles per hour We are near our terminal velocity Expected retro Rocket ignition on my mark – Mark. At this point in time, we should be on the ground Any signal that we receive from now indicates the vehicle would be alive on the ground and bouncing The Spacecraft has to survive all the bounces for landing to be a success No signal at the moment Standby Signal strength is currently intermittent We don’t see a signal at the moment What do we see? We’ve got the signal! The first thing we have to do after we land is open our solar panels to the sun So we’ll have some power.
This charges up the batteries After that, we can deploy the camera mast so the rover can see and deploy the antenna, so the rover can talk to us .

From Wiki : Spirit, MER-A (Mars Exploration Rover — A), is a robotic rover on Mars, active from 2004 to 2010. It was one of two rovers of NASA’s ongoing Mars Exploration Rover Mission. It landed successfully on Mars at 04:35 Ground UTC on January 4, 2004, three weeks before its twin, Opportunity (MER-B), landed on the other side of the planet. Its name was chosen through a NASA-sponsored student essay competition. The rover became stuck in late 2009, and its last communication with Earth was sent on March 22, 2010.
The rover completed its planned 90-sol mission. Aided by cleaning events that resulted in higher power from its solar panels, Spirit went on to function effectively over twenty times longer than NASA planners expected following mission completion. Spirit also logged 7.73 km (4.8 mi) of driving instead of the planned 600 m (0.4 mi), allowing more extensive geological analysis of Martian rocks and planetary surface features. Initial scientific results from the first phase of the mission (the 90-sol prime mission) were published in a special issue of the journal Science.
On May 1, 2009 (5 years, 3 months, 27 Earth days after landing; 21.6 times the planned mission duration), Spirit became stuck in soft soil. This was not the first of the mission’s “embedding events” and for the following eight months NASA carefully analyzed the situation, running Earth-based theoretical and practical simulations, and finally programming the rover to make extrication drives in an attempt to free itself. These efforts continued until January 26, 2010 when NASA officials announced that the rover was likely irrecoverably obstructed by its location in soft soil, though it continued to perform scientific research from its current location.
The rover continued in a stationary science platform role until communication with Spirit stopped on sol 2210 (March 22, 2010). JPL continued to attempt to regain contact until May 24, 2011, when NASA announced that efforts to communicate with the unresponsive rover had ended. A formal farewell was planned at NASA headquarters after the Memorial Day holiday and was televised on NASA TV.
Hope you enjoyed it!
