Pour fêter les premiers essais de prélèvement d'échantillons par @NASAPersevere, le dossier dédié à la fascinante thématique de la protection planétaire a été mis en ligne. Il clôture une trilogie consacrée à la campagne de retour d'échantillons martiens :

@Gaby65 @NASAJPL @CNES @InSight_IPGP Ce fut en effet une soirée inoubliable à tout point de vue.

@EtienneKlein 😔

@MarkPanning Great testbed ! You can even use Marie Curie’s lab to mimick the Moon’s far side radiation level 😅

[Philippe @NirgalMars]

@VR2Planets @HiRISE Each time I see your videos, I feel sad by the fact that these 2D rendering don’t do justice at all to the real VR experience that is indeed offered by your work. This is also especially true for the wonderful and underrated @NASAInSight VR deployment module.

[Philippe @NirgalMars]

@CNES Il y a une inexactitude dans la question sur l’EDL. Difficile d’être clair et concis ici sans gâcher immédiatement cette dernière, mais la durée de l’EDL (rappelée dans sa dénomination symbolique) ne coincide pas vraiment avec l’effet du plasma lorsque ce dernier entoure la sonde

[Philippe @NirgalMars]

@MoonNext @PicduMidi @IRAP_France @ISAE_officiel J’ai froid rien qu’en voyant les images. Je ne savais pas que le Stellina était qualifié pour de telles conditions !

[Philippe @NirgalMars]

@MarkPanning I’ve been looking for « investigating quantic seismic activity on Moon far side » on Google, but didn’t find anything !

[Philippe @NirgalMars]

@MarkPanning Any link yet ?

[Philippe @NirgalMars]

Sauf erreur, c’est la première photographie publique montrant un satellite dans son entièreté en orbite autour de Mars. Jusqu’à présent nous n’avions que des dessins d’artiste. Reste à espérer que la mini-caméra soit stérile et désorbite rapidement !

[Philippe @NirgalMars]

Sur Mars au moins, l’année commence bien.

[CNSA Watcher @CNSAWatcher]

Wow! Here we have astonishing HD “selfies” of Tianwen-1 Mars orbiter. Technically it’s taken by companion little satellite released by Tianwen in orbit and data is transmitted back to Tianwen via WiFi. Also released are new photos of Mars North Pole and Zhurong’s recent panorama.

[NASA JPL @NASAJPL]

⚙️ We're testing ways to bring Mars samples back to Earth. Engineers are developing crucial hardware for the series of daring Mars Sample Return missions. Prototypes for important robotics are undergoing tests here at JPL, @NASA_Marshall and @NASA_Langley. https://t.co/ayoPWOO3tA

[Chinese Zhurong Mars Rover @MarsZhurong]

#Zhurong Mars rover research team published “Geomorphic contexts and science focus of the Zhurong landing site on Mars” in Nature Astronomy on Dec 6, which introduced Zhurong's exploration route and results taken by high-res cameras of #Tianwen1 orbiter. https://t.co/r8Rp4cPR9U

[Philippe @NirgalMars]

It's time for a sampling briefing !

[ARCHIVED - NASA's Perseverance Mars Rover @NASAPersevere]

All the latest on #SamplingMars: Join my team live today (9 a.m. PDT/noon EDT/1600 UTC) for fresh updates on what I’ve been up to and what comes next. https://t.co/Q24DiF42q0

[Philippe @NirgalMars]

@MarkPanning But is it dead or alive ? 😅

[Philippe @NirgalMars]

@NASAJPL @NASAPersevere @NASA @esa #askNASA Could you share some details about the rock petrology/identity ? Was the second sampling mainly for engineering or scientific purpose ?

[NASA JPL @NASAJPL]

Now that we've got our first Mars core samples, join us on Sept. 10 at 9am PT (noon ET/1600 UTC) as @NASAPersevere experts discuss what we’ve learned and what it means for the @NASA-@ESA Mars Sample Return campaign. Use #askNASA to submit questions. https://t.co/5PHhxYaxc9

[Philippe @NirgalMars]

@Gaby65 @NASAPersevere @NASAJPL I hope they will share some information about “Rochette” petrology ! 🥳

[ARCHIVED - NASA's Perseverance Mars Rover @NASAPersevere]

I’ve got it! With better lighting down the sample tube, you can see the rock core I collected is still in there. Up next, I’ll process this sample and seal the tube. #SamplingMars

[Philippe @NirgalMars]

@steltzner Still, the tube #233 should be full of martian atmosphere, and surely must be returned to Earth ! It’s also an amazing proof of Human ingenuity.
