Robotic NASA Craft Begins Orbiting Mars for Most-Detailed Exam (10.03.2006)

With a crucially timed firing of its main engines today, NASA's new mission to Mars successfully put itself into orbit around the red planet.

Signals received from the spacecraft at 2:16 p.m. Pacific Time after it emerged from its first pass behind Mars set off cheers and applause in control rooms at NASA's Jet Propulsion Laboratory, Pasadena, Calif., and at Lockheed Martin Space Systems, Denver.

"This is a great milestone to have accomplished, but it's just one of many milestones before we can open the champagne," said Colleen Hartman, deputy associate administrator for NASA's Science Mission Directorate. "Once we are in the prime science orbit, the spacecraft will perform observations of the atmosphere, surface, and subsurface of Mars in unprecedented detail."

The spacecraft traveled about 500 million kilometers (310 million miles) to reach Mars after its launch from Florida on Aug. 12, 2005. It needed to use its main thrusters as it neared the planet in order to slow itself enough for Mars' gravity to capture it. The thruster firing began while the spacecraft was still in radio contact with Earth, but needed to end during a tense half hour of radio silence while the spacecraft flew behind Mars.

"Our spacecraft has finally become an orbiter," said JPL's Jim Graf, project manager for the mission. "The celebration feels great, but it will be very brief because before we start our main science phase, we still have six months of challenging work to adjust the orbit to the right size and shape."

Ili za jos vecu  :?  "slichicu" :


citiram: "The quality of this test image is spectacular, with no hint to the eye of any smear or blurring. A high signal-to-noise ratio reveals fine details even in the shadows."

Treba obratiti paznju na "even in the shadows"! :)

Kamera visoke rezolucije, postavljena na najnovijoj letelici američke svemirske agencije NASA, koja je krenula put Marsa, poslala je prve slike 'crvene planete' iz orbite, saopštila je NASA.

Crno-bele fotografije, koje su u četvrtak uveče, sa visine od skoro 2.500 kilometara, zabeležile tri kamere, prikazuju južnu oblast Marsa u obimu 50 puta 19 kilometara, prenele su agencije.

Na mozaiku od deset fotografija vidi se površina Marsa u pukotinama i dubokim brazdama, što je najverovatnije formirala voda, izjavio je Alfred Mekeven, naučnik koji učestvuje u ovoj misiji i profesor na Univerzitetu Arizona.

Letelica se domogla orbite 10. marta i zabeležiće prostor od jedan odsto površine Marsa, a ta mapa će poslužiti u budućim sletanjima robota i ljudi.

Kod ovih slika krater uvek izgledao kao brdo :)

Super slika u svakom slučaju.
