Curiosity on track

Obama must have planned this visit to Mars just to make himself look good!  What a tyrant!  An evil genius!


NASA's Curiosity rover edges closer to Mars

The Curiosity rover remains perfectly on course to make its Monday (GMT) landing on the Red Planet.
The Nasa robot's flight trajectory is so good engineers cancelled the latest course correction they had planned.
To be sure of touching down in the right place on the surface, the vehicle must hit a box at the top of the atmosphere that is just 3km by 12km.
"Our inbound trajectory is right down the pipe," said Arthur Amador, Curiosity's mission manager.
"The team is confident and thrilled to finally be arriving at Mars, and we're reminding ourselves to breathe every so often. We're ready to go."
The rover's power and communications systems are in excellent shape.
The one major task left for the mission team is to prime the back-up computer that will take command if the main unit fails during the entry, descent and landing (EDL) manoeuvres.
Curiosity - also known as the Mars Science Laboratory - has spent the past eight months travelling from Earth to Mars, covering more than 560 million km.
The robot was approaching Mars at about 13,000km/h on Saturday. By the time the spacecraft hits the top of Mars' atmosphere, about seven minutes before touch-down, gravity will have accelerated it to about 21,000km/h.

The vehicle is being aimed at Gale Crater, a deep depression just south of the planet's equator.
It is equipped with the most sophisticated science payload ever sent to another world.
Its mission, when it gets on the ground, is to characterise the geology in Gale and examine its rocks for signs that ancient environments on Mars could have supported microbial life.
Touch-down is expected at 05:31 GMT (06:31 BST) Monday 6 August; 22:31 PDT, Sunday 5 August.
Facts about the mission:

  • Mission goal is to determine whether Mars has ever had the conditions to support life
  • Project costed at $2.5bn; will see initial surface operations lasting two Earth years
  • Onboard plutonium generators will deliver heat and electricity for at least 14 years
  • 75kg science payload more than 10 times as massive as those of earlier US Mars rovers
  • Equipped with tools to brush and drill into rocks, to scoop up, sort and sieve samples
  • Variety of analytical techniques to discern chemistry in rocks, soil and atmosphere
  • Will try to make first definitive identification of organic (carbon-rich) compounds
  • Even carries a laser to zap rocks; beam will identify atomic elements in rocks
