Rzeczywiście w 36 locie coś poszło nie tak, bo ze zdjęć wynika, że poleciał i wrócił na miejsce startu.

Jest oficjalne potwierdzenie udanego 36 lotu. Czyli skoro przeleciał w sumie 110 metrów, to w jedną stronę zrobił 55 metrów i w drugą 55.

Zakładam, ale moim zdaniem byłoby to dziwny manewr, że helikopterek sam sobie nie wrócił do punktu wyjścia. Celowy zabieg kontrolerów? Dystans do Percy rośnie, a ktoś tu wspominał bodajże o ledwo kilometrowym zasięgu radiowym względem obu robotów.

Perseverance odkrył zawiązki organiczne w kraterze Jezero:

Previously, NASA’s Curiosity rover discovered organics in Gale Crater, but the molecules identified by Perseverance are found in rocks that are very different from those spotted by Curiosity.

The new findings have been reported in a collection of papers published in the journal Science.

Perseverance dojechał do Three forks i wkrótce rozpocznie składowanie wypełnionych próbkami Marsa tub:

In the coming days, NASA's Perseverance rover is expected to begin building the first sample depot on another world. This will mark a crucial milestone in the NASA-ESA (European Space Agency) Mars Sample Return campaign, which aims to bring Mars samples to Earth for closer study.

The depot-building process starts when the rover drops one of its titanium sample tubes carrying a chalk-size core of rock from its belly 2.9 feet (88.8 centimeters) onto the ground at an area within Jezero Crater nicknamed "Three Forks." Over the course of 30 or so days, Perseverance will deposit a total of 10 tubes that carry samples representing the diversity of the rock record in Jezero Crater.

"Up to now, Mars missions required just one good landing zone; we need 11," said Richard Cook, Mars Sample Return program manager at NASA's Jet Propulsion Laboratory in Southern California. "The first one is for the Sample Retrieval Lander, but then we need 10 more in the vicinity for our Sample Recovery Helicopters to perform takeoffs and landings, and driving too."

After settling on a suitable site, the campaign's next task was to figure out exactly where and how to deploy the tubes within that location. "You can't simply drop them in a big pile because the recovery helicopters are designed to interact with only one tube at a time," said Cook. The helicopters are intended to serve as a backup, just like the depot. To ensure a helicopter could retrieve samples without disturbing the rest of the depot or encountering any obstructions from the occasional rock or ripple, each tube-drop location will have an "area of operation" at least 18 feet (5.5 meters) in diameter. To that end, the tubes will be deposited on the surface in an intricate zigzag pattern, with each sample 16 to 49 feet (5 to 15 meters) apart from one another.

Po wyłożeniu tub z próbkami rozpocznie się faza misji Mars Rover 2020 zwana ,,Delta Top" w czasie której łazik ma wspiąć się na szczyt delty i badać tamtejsze skały w tym przyniesione z dalszych okolic:

"We will still be working the sample depot deployment when our extended mission begins on Jan. 7, so nothing changes from that perspective," said Art Thompson, Perseverance's project manager at JPL. "However, once the table is set at Three Forks, we'll head to the top of the delta. The science team wants to take a good look around up there."

Called the Delta Top Campaign, this new science phase will begin when Perseverance finishes its ascent of the delta's steep embankment and arrives at the expanse that forms the upper surface of the Jezero delta, probably sometime in February. During this approximately eight-month campaign, the science team will be on the lookout for boulders and other materials that were carried from elsewhere on Mars and deposited by the ancient river that formed this delta.

"The Delta Top Campaign is our opportunity to get a glimpse at the geological process beyond the walls of Jezero Crater," said JPL's Katie Stack Morgan, deputy project scientist for Perseverance. "Billions of years ago a raging river carried debris and boulders from miles beyond the walls of Jezero. We are going to explore these ancient river deposits and obtain samples from their long-traveled boulders and rocks."

A tutaj będzie najprawdopodobniej składowana pierwsza tuba z próbkami:

Tak mnie zastanawia czy marsjański wiatr nie przykryje z czasem tych próbek grubą (może nawet zbyt grubą) warstwą piasku... Może to yć spora przeszkoda w odszukaniu czy odzyskaniu takiej próbki.

Jutro lot 38.

Wiele osób nad tym się zastanawiało, a zespół uważa, że wiatr lub marsjański pył nie będzie stanowić problemu. To jest opcja zapasowa odłożona na wypadek, gdyby nie był w stanie łazik dostarczyć głównego zestawu próbek bezpośrednio do następnego lądownika. W takim przypadku zostałyby one zebrane przez jeden z dwóch helikopterów do odzyskiwania próbek. Jeśli wszystko pójdzie zgodnie z planem, ten zestaw zapasowy pozostanie tutaj, podczas gdy Percy dostarczy podstawowy zestaw.
