Pa prate ljudi. Dok je radio brojač registrirao sam i preko stotinjak otvaranja.
Danas  ne znam koliko, ali predpostavljam da se čita...
Iznenađuje kolko ih malo, ili skoro nikako, komentira.

Vozilo već tjedan dana ima problem s računalom...
Imali su već problem s prvim računalom, od dva. 
Evo sad i s ovim...a riješit će to NASA.

Curiosity will switch back to the Side A computer. Side B still problematic.

Curiosity Rover to Temporarily Switch 'Brains'

NASA Curiosity Mission Status Report
Engineers at NASA's Jet Propulsion Laboratory in Pasadena, California, this week commanded the agency's Curiosity rover to switch to its second computer. The switch will enable engineers to do a detailed diagnosis of a technical issue that has prevented the rover's active computer from storing science and some key engineering data since Sept. 15.
Like many NASA spacecraft, Curiosity was designed with two, redundant computers -- in this case, referred to as a Side-A and a Side-B computer -- so that it can continue operations if one experiences a glitch. After reviewing several options, JPL engineers recommended that the rover switch from Side B to Side A, the computer the rover used initially after landing.
The rover continues to send limited engineering data stored in short-term memory when it connects to a relay orbiter. It is otherwise healthy and receiving commands. But whatever is preventing Curiosity from storing science data in long-term memory is also preventing the storage of the rover's event records, a journal of all its actions that engineers need in order to make a diagnosis. The computer swap will allow data and event records to be stored on the Side-A computer.
Side A experienced hardware and software issues over five years ago on sol 200 of the mission, leaving the rover uncommandable and running down its battery. At that time, the team successfully switched to Side B. Engineers have since diagnosed and quarantined the part of Side A's memory that was affected so that computer is again available to support the mission.
"At this point, we're confident we'll be getting back to full operations, but it's too early to say how soon," said Steven Lee of JPL, Curiosity's deputy project manager. "We are operating on Side A starting today, but it could take us time to fully understand the root cause of the issue and devise workarounds for the memory on Side B.
"We spent the last week checking out Side A and preparing it for the swap," Lee said. "It's certainly possible to run the mission on the Side-A computer if we really need to. But our plan is to switch back to Side B as soon as we can fix the problem to utilize its larger memory size."

Evo, nakon 17 dana prva pristigla fotografija. 
Uspjeli su se prebacit na računalo A.
Slijedi popravak softvera na računalu B i 
eventualno prebacicvanje na računalo B,
koje ima veći kapacitet. 

Sol 2204: Curiosity Science is Baaaack!
Curiosity Rover Mission Update
By Sarah Lamm on October 19, 2018
Contrary to the "frightening" title, the Curiosity team is excited that science operations are starting to resume! The real fright was when Curiosity had an anomaly on Sol 2172 which affected its memory. Since then, the engineering team has continued to diagnose the anomaly and plan the recovery, including taking the first images with the A-side engineering cameras that haven't been used since 2013! Thanks to our hard-working engineers, Curiosity is ready for limited science operations while the anomaly work continues.
Curiosity has been at the (sadly) unsuccessful "Inverness" drill site since the anomaly. Curiosity is still exploring the gray Jura member on Vera Rubin Ridge. The uplink plan for Sol 2204 includes the use of RAD, REMS, and DAN (active and passive).
RAD detects high-energy radiation on the Martian surface. RAD's data will help shape future human mission to Mars by letting us know how much shielding from radiation future Mars astronauts will need to protect them. REMS (Rover Environmental Monitoring Station) is Curiosity's weather station. REMS can measure pressure, humidity, ultraviolet radiation, and temperature. DAN (Dynamic Albedo of Neutrons) detects neutrons that be used to measure the amount of hydrogen and other elements in the subsurface.

Dates of planned rover activities described in these reports are subject to change due to a variety of factors related to the Martian environment, communication relays and rover status.
