NASA's $2.5 billion dream machine, the Mars Science Laboratory, aims to accept steps toward discovering if this gets near Mars' surface on Monday.
The earth is Earth's nearest neighbor, and researchers have discovered indications of water there, hinting that some type of existence used to be likely, despite the fact that Mars has become a dry place having a thin atmosphere, extreme winters and dirt storms.
NASA stated it'll discover if it is Mars Science Laboratory and rover, Curiosity -- made to search for soil-based signatures of existence and send back data to organize for any future human mission -- arrived securely at 1:31 am Eastern time (0531 GMT) on Monday.
That'll be about 14 minutes following the touchdown really happens because of time it requires for spacecraft signals to visit from Mars to Earth.
Lately Saturday, the laboratory was roughly 261,000 miles (420,039 kilometers) from Mars, closing in around 8,000 mph (13,000 kilometers each hour).
"Curiosity remains in good health with all systems operating as expected," NASA stated inside a statement.
The nuclear-powered rover may be the greatest ever designed for planetary exploration, coming in at one ton, about how big a little vehicle, and has a complex chemistry package to zap rocks, drill soil and test for radiation.
The landing is really a daring and unparalleled maneuver which involves penetrating the climate in a speed of 13,200 mph (21,240 kilometers each hour), slowing down lower with the aid of a supersonic parachute and shedding lower lightly with tethers from the rocket-powered sky crane.
"This is the most challenging landing we have ever attempted," stated Doug McCuistion, director of NASA's Mars Exploration Program.
Two NASA orbiters is going to be crossing overhead because the Lander approaches the top, along with a third orbiter operated through the European Space Agency will even send data to Earth.
The Mars Science Laboratory started its journey towards the Red-colored Planet a lot more than eight several weeks ago if this released in the Florida coast at the end of November 2011.
"It gets scarier every day," stated McCuistion, observing that no more than 40 % of past attempts by global space agencies to transmit spacecraft to Mars have been successful.
"Can we do this? Yeah, I think we can do this. I am confident the team has done an amazing job. We have the A-plus team on this. They have done everything possible to ensure success," he stated.
"But that risk still exists. It is going to be tough."
NASA has detailed the ultimate minutes from the complex landing within an Internet video known as "Seven Minutes of Terror." An active broadcast from mission control in Pasadena, California is going to be on world wide web.nasa.gov beginning at 0330 GMT Monday.
The landing site for that rover is really a flat area referred to as Gale Crater, which lies near a mountain that researchers hope the rover will have the ability to climb in the quest for sediment layers that may be up to and including billion years of age.
One potential factor of interest, the elements, seems to become cooperating following a nearby dust storm spotted days ago dissipated, deputy project researcher Ashwin Vasavada told reporters.
"Mars is playing nice and we are going to get good conditions for Sunday," he stated.
Vasavada stated the dust storm close to the landing site has developed right into a "fairly harmless cloud of dust" that most likely won't achieve Gale Crater when from the landing.
He stated it wasn't "expected to affect entry, descent and landing in any meaningful way."
When the landing goes based on plan, NASA wishes to possess some low-resolution black and whitened images obtained from cameras around the rear from the rover shortly after.
More images follows within the future. Then, engineers on the planet will expend the majority of August remotely looking at systems around the vehicle, based on deputy program manager Richard Prepare.
The rover is transporting a chemistry package that consists of a rock-zapping laser, 17 cameras, a drill, radiation sensors, water sensors, and tools to scoop soil and appearance for carbon-based compounds which are the inspiration for existence.
Curiosity may begin to roll because of its first drive in September, using its first scoop samples expected late within the month and it is first drilling attempt in October or November.
When the landing fails, McCuistion vowed that NASA would continue its efforts to understand more about Mars.
"We will pick ourselves up and dust ourselves off. We will look at this and do something again. We will do it again, this will not be the end," he stated.
