PER2: tohle je takova periodicky se opakujici otazka :) Takze, jak na to? Nijak...je to slozity, tezky a vzhledem k tomu na jak dlouho se tyhle mise planuji, zbytecny...InSight mel planovanou dobu mise 728 dni a tu zvladl, vse nad je jen bonus. Ono je potreba vzit v potaz vsechno co se na tom cisticim systemu muze pokazit a jak by to mohl ovlivnit celou misi. Takze cim jednodusi tim lepsi ;)

SEJDA: jo jasne, jak tezky to muze byt problem, nemusi to byt absolutne spickove vycisteny prece? nejaky stupidni kartacek co to prejede na povel ze zeme, jaky mas moznosti? bud ti sonda umre, protoze nema energii, pac mas na solarech tunu prachu nebo neco poskodis cistenim a sonda ti umre taky no a nebo prodlouzis zivotnost o dalsi pulrok reba?
ted na solary "sypali prach z marsu kdyz foukalo", aby je ocistili ... jako co muze byt horsi? :)

The InSight team came up with what seems like a counterintuitive idea to help clear the dust off the panels. "The lander's robotic arm trickled sand near one solar panel, helping the wind to carry off some of the panel's dust," NASA said in a statement on Thursday. "The result was a gain of about 30 watt-hours of energy per sol, or Martian day."

Mise InSight se chýlí ke konci:
As the power available to NASA’s InSight Mars lander diminishes by the day, the spacecraft’s team has revised the mission’s timeline in order to maximize the science they can conduct. The lander was projected to automatically shut down the seismometer – InSight’s last operational science instrument – by the end of June in order to conserve energy, surviving on what power its dust-laden solar panels can generate until around December.
Instead, the team now plans to program the lander so that the seismometer can operate longer, perhaps until the end of August or into early September. Doing so will discharge the lander’s batteries sooner and cause the spacecraft to run out of power at that time as well, but it might enable the seismometer to detect additional marsquakes.

ARCHIMEDES: Trvalo to, ale alespoň tu největší hovadinu opravili.

KAERO: "Kdo mohl cekat, ze budou jako lidi".
Ted mne napadlo, ze by cela ta cinska akce mohl byt pokus vedecke spolecnosti, jak nastartovat obnovu Areciba :D Tento krat ale v XL variante :D

SEJDA: mohla by byt i horsi varianta. V jedne SF povidce pristali emzaci, a lidstvo se s nima furt nemohlo domluvit. Az se za velkych obtizi par lidi naucilo emzackou rec. Ti lide pak vysvetlili, ze emzaci lidem celou dobu rozumeli, jen nechteli mluvit zadnou lidskou reci. Povidka konci vetou: "Kdo mohl cekat, ze budou jako francouzi."

SUMAC: lol, a muzeme natacet vsechna Sci-Fi znovu, akorat ze za lidstvo nebudou vyjednavat Americane ale Cinani :)

SUMAC: tak to doufam, že se číňani nerozhodnou komunikovat s něma skrze Slunce, mě tento 3D prostor oproti jeho 2D docela ještě baví :-) (hint: Problém3 těles)

There's some reporting that the 500-meter aperture FAST radio telescope in Guizhou, China has detected candidates for signals from extraterrestrial intelligence, including a suspicious signal from exoplanet target observation data. This is interesting, but don't get too excited.
