Is it possible that Curiosity Rover measured its own methane or failed doing the spectrometry?

I am Jose Juan Lopez Moreno, co-I (co-investigator) of TGO-NOMAD and I feel obliged to respond to PearsonArtPhoto's answer. There is something real: TGO carries 2 independent instruments with a ...

Is it possible that Curiosity Rover measured its own methane or failed doing the spectrometry?

There's a lot to unpack here, so let's look at the various discoveries of methane on Mars. The first discovery came from multiple groups in 2003-2004 using first Mars Express, followed by Earth ...

If the ESA has its own deep space network, why does it use NASA's?

The DSN is used alongside ESTRACK. For Rosetta, for example: NASA’s DSN network has provided continuing, routine support to the Rosetta mission since the start of the mission (see “Tracking the ...

Is the ESA Roscosmos ExoMars Orbiter capable of detecting the NASA landers and rovers on the surface of Mars?

Unfortunately not (really). The CaSSIS imager on board ExoMars's Trace Gas Orbiter has a resolution from its ~400km orbit of around 4.6m/pixel. This means that it might be possible to identify a ...

Is the ESA Roscosmos ExoMars Orbiter capable of detecting the NASA landers and rovers on the surface of Mars?

tl;dr: Yes it's possible, but it would be a challenge. I am pretty sure that in time, 4.6 meter/pixel imaging (from @simplex1's answer) could find InSight. It might take a while and a lot of work ...

Is the ESA Roscosmos ExoMars Orbiter capable of detecting the NASA landers and rovers on the surface of Mars?

Yes! Just barely. On Feb 23th ExoMars spotted Perseverance, its parachute, descent stage, and heat shield with its 4.5 m per pixel color stereo surface imaging camera (CaSSIS). Of course, it helped ...

Magnetic Memory to Mars?

ExoMars is not the first use of MRAM. In 2007, SpriteSat was launched with MRAM in its magnetometer subsystem. In 2012, JPL tested an MRAM unit for radiation resistance. No latchup observed ...

How will the Exomars rover communicate back to Earth?

Yes, it always needs an orbiter to communicate with Earth. The ExoMars Trace Gas Orbiter, part of the 2016 ExoMars mission, will support communications. The Rover Operations Control Centre (ROCC) ...

Is it possible that Curiosity Rover measured its own methane or failed doing the spectrometry?

July 2021 update: It's a daily variation, not an instrument problem A NASA article explains that the difference between the methane measurements of Curiosity and the Trace Gas Orbiter is due to the ...

How will the Exomars rover communicate back to Earth?

The answer by @Hobbes covers the first question well - there always needs to be an orbiter to act as a relay. (If you are only working with solar power, direct-to-earth comms is a bit of a stretch.) ...

Could the NOMAD instrument on the TGO detect methane at night with sufficient reflected sunlight or artificial light?

Not according to this NASA article: The Trace Gas Orbiter, on the other hand, requires sunlight to pinpoint methane about 3 miles, or 5 kilometers, above the surface.
