[Space] NASA - Mars Exploration Rover MER-B "Opportunity" - Update Thread

[jumpjack]

Si leggono cose strane in questi giorni in rete (per la verità la notizia è di aprile ma io l'ho letta ora...)
"si dice" che è stato fotografato "per la prima volta" il luogo di atterraggio di Opportunity, o, peggio ancora, il "cratere lasciato da Opportunity".

In realtà, nel 2004 Opportunity, dopo vari rimbalzi sui suoi aribag, andò ad atterrare proprio dentro un piccolo cratere (pre-esistente), e di lì a poco fu fotografato dall'orbita dal Mars Global Surveyor (MGS).

Adesso, per la prima volta è stato fotografato anche da Mars Reconaissance Orbiter, in alta risoluzione e a colori.

Mission Control is still receiving evidence that Opportunity is slowly rolling, which is expected.


0516 GMT (12:16 a.m. EST)

The roll continues -- more than 10 minutes after the impact.


0517 GMT (12:17 a.m. EST)

Opportunity is still moving!

Sniff...
Chissà, forse un giorno riusciremo ad andarlo a prendere.

Grande Jump! ( per tutto, inclusi gli anni!)

Grazie per le tante avventure e scoperte all'incredibile Opportunity...

5352 SOLS

Missione durata oltre 55 volte la stima iniziale.

Che dire, niente se non #ThankYouOppy!

NASA's Record-Setting Opportunity Rover Mission on Mars Comes to End

One of the most successful and enduring feats of interplanetary exploration, NASA's Opportunity rover mission is at an end after almost 15 years exploring the surface of Mars and helping lay the groundwork for NASA’s return to the Red Planet.

The Opportunity rover stopped communicating with Earth when a severe Mars-wide dust storm blanketed its location in June 2018. After more than a thousand commands to restore contact, engineers in the Space Flight Operations Facility at NASA's Jet Propulsion Laboratory (JPL) made their last attempt to revive Opportunity Tuesday, to no avail. The solar-powered rover's final communication was received June 10.

"It is because of trailblazing missions such as Opportunity that there will come a day when our brave astronauts walk on the surface of Mars," said NASA Administrator Jim Bridenstine. "And when that day arrives, some portion of that first footprint will be owned by the men and women of Opportunity, and a little rover that defied the odds and did so much in the name of exploration."

Designed to last just 90 Martian days and travel 1,100 yards (1,000 meters), Opportunity vastly surpassed all expectations in its endurance, scientific value and longevity. In addition to exceeding its life expectancy by 60 times, the rover traveled more than 28 miles (45 kilometers) by the time it reached its most appropriate final resting spot on Mars – Perseverance Valley.

"For more than a decade, Opportunity has been an icon in the field of planetary exploration, teaching us about Mars' ancient past as a wet, potentially habitable planet, and revealing uncharted Martian landscapes," said Thomas Zurbuchen, associate administrator for NASA's Science Mission Directorate. "Whatever loss we feel now must be tempered with the knowledge that the legacy of Opportunity continues – both on the surface of Mars with the Curiosity rover and InSight lander – and in the clean rooms of JPL, where the upcoming Mars 2020 rover is taking shape."

The final transmission, sent via the 70-meter Mars Station antenna at NASA's Goldstone Deep Space Complex in California, ended a multifaceted, eight-month recovery strategy in an attempt to compel the rover to communicate.

“We have made every reasonable engineering effort to try to recover Opportunity and have determined that the likelihood of receiving a signal is far too low to continue recovery efforts," said John Callas, manager of the Mars Exploration Rover (MER) project at JPL.

Opportunity landed in the Meridiani Planum region of Mars on Jan. 24, 2004, seven months after its launch from Cape Canaveral Air Force Station in Florida. Its twin rover, Spirit, landed 20 days earlier in the 103-mile-wide (166-kilometer-wide) Gusev Crater on the other side of Mars. Spirit logged almost 5 miles (8 kilometers) before its mission wrapped up in May 2011.

From the day Opportunity landed, a team of mission engineers, rover drivers and scientists on Earth collaborated to overcome challenges and get the rover from one geologic site on Mars to the next. They plotted workable avenues over rugged terrain so that the 384-pound (174-kilogram) Martian explorer could maneuver around and, at times, over rocks and boulders, climb gravel-strewn slopes as steep as 32-degrees (an off-Earth record), probe crater floors, summit hills and traverse possible dry riverbeds. Its final venture brought it to the western limb of Perseverance Valley.

"I cannot think of a more appropriate place for Opportunity to endure on the surface of Mars than one called Perseverance Valley," said Michael Watkins, director of JPL. "The records, discoveries and sheer tenacity of this intrepid little rover is testament to the ingenuity, dedication, and perseverance of the people who built and guided her."

Tranquillo, tra 30 anni ci sarà su MarsAdvisor la recensione dell' "Opportunity resting site" tra quelle dei "posti da vedere su Marte almeno una volta nella vita" e ci si potranno fare selfie accanto a Opportunity.
