Engineers in the NASA Laboratory for Reactive Movement in Pasadena,
California, began sending a new set of commands to Opportunity rover
in an attempt to force The 15-year-old Martian
Explorer to connect with the Earth. New commands to be sent to
over the next few weeks, will deal with low-probable events that they could
have arisen on board an Opportunity that prevents its transmission.
The last communication of the Rover with the Earth was received on June 10, 2018 as dust from the whole planet
covered the location of the solar engine on Mars.
"We have and will continue to use a multitude
techniques in our attempts to connect with the burger, "said John Callas,
JPL project manager. "These new command strategies are."
in addition to the "sweep" and "beep" commands we passed to
on the verge of September. "With" cleaning and beep "instead of just listening
Option, the project sends commands to the widget to react back with a
new delivery strategies are expected to last for several weeks. They turn
three possible scenarios: that the main radio frequency radio on the Rover – which option
used to communicate with the Earth – failed; that its main and
Secondary X-band radio stations have failed; or that the internal clock of the rover, which
provides a time frame for computer brain, is compensated. A.
a series of unlikely events should occur for each of them
errors will occur. Mostly,
the potential remedies used to deal with these incredible events include: a
command to switch the burst to backup radio and radio signals
aimed at clock reset and UHF response.
"Over the last seven months, we tried to get in touch
Opportunity over 600 times, "said Kallas. Until we have heard
and the probability we will ever have, decreases each
day, we plan to continue to pursue any logical solution that can make us
going back. "
Time is essential for the Opportunity team. Clearing dust

or these additional transmission strategies, or "cleaning and audible signals" generate
as a response from the Mars, engineers could try to recover. If you have the opportunity
does not respond, the project team will again consult the Mars Program at JPL and NASA
The plant to set the way forward.
