„How To get to Mars” is a clip from the IMAX documentary „Roving Mars” from 2006. This is an edited short version.
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.
„Let’s be real, how can you control a ship and its over 54.6 million kilometers distance away? how can you be precise in seconds before landing? ”
„This video is not even NASA, the rocket shown was falcon reusable rocket made by spaceX, and the NASA guys cheering probably just added from a different video,it is an animation to show the beauty of the Merlin engine used in falcon rocket, as the weight to lift ratio is the most efficient,and as you can see in the separation stage the part has small booster called trajectory control so the main engine and subsequent part can be controlled to where it would fall and the falling speed so it can be used again,the concept is that reusable rocket can cut down mission cost by a large amount,so the mars mission is feasible to non government such as spaceX thanks to the innovation of the company,I don’t know why the maker of this video mix different scene of the mission simulation with NASA guys cheering but just remember that IT IS CGI made to simulate the falcon,but if you don’t believe in mainstream media and humanity advancement then I hope one day you can win a Nobel prize by actually building a company and going to space to actually proof the flat earth theory by yourself as some guy on the internet are sure can’t just tell you to start to believe in something so weird as a round earth right?”
