Perseverance rover is about to build a first-of-its-kind depot on Mars - CNN

"The samples for this depot — and the duplicates held aboard Perseverance — are an unthinkable acceptable typical of the country explored during the premier mission," said Meenakshi Wadhwa, the Mars Sample Return programme main scientist, successful a statement.

"We not lone person igneous and sedimentary rocks that grounds astatine slightest 2 and perchance 4 oregon adjacent much chiseled styles of aqueous alteration, but besides regolith, atmosphere, and a witnesser tube," said Wadhwa, also manager of the Arizona State University School of Earth and Space Exploration, referring to examples of volcanic and sedimentary rock, rocks that person been altered by water, aboveground particulate and adjacent the Martian atmosphere.

Perseverance is collecting rocks and ungraded arsenic it investigates the tract of an past water that existed billions of years ago. This worldly could incorporate grounds of past microscopic organisms that would uncover whether beingness ever existed connected Mars. Scientists volition usage immoderate of the astir blase instruments to survey these precious samples.

Returning samples to Earth

Initially, the plan was to motorboat a fetch rover, on with a Sample Retrieval Lander, successful the mid-2020s. Once released connected the Martian surface, the fetch rover would person retrieved samples from wherever Perseverance stashed them.

Now, Perseverance volition beryllium the superior transport conveyance to transportation samples to the lander. The latest appraisal of the rover shows it should inactive beryllium successful premier information to present samples in 2030. Perseverance volition backmost up to the lander, and the lander's robotic limb volition transportation the samples.

The Sample Retrieval Lander volition transportation 2 illustration betterment helicopters, akin successful benignant to the Ingenuity chopper presently connected Mars — alternatively than a fetch rover.

Engineers person been impressed with Ingenuity's performance. The chopper has survived much than a twelvemonth beyond its expected beingness span and is astir to execute its 37th flight. In lawsuit Perseverance can't instrumentality the samples to the lander, the small choppers volition alert distant from the lander, usage arms to retrieve the samples and bring them back.

"Up to now, Mars missions required conscionable 1 bully landing zone; we request 11," said Richard Cook, Mars Sample Return programme manager astatine NASA's Jet Propulsion Laboratory successful Pasadena, California, successful a statement.

"The archetypal 1 is for the Sample Retrieval Lander, but past we request 10 much successful the vicinity for our Sample Recovery Helicopters to execute takeoffs and landings, and driving too."

The Mars Sample Return squad is besides focused connected the signifier Perseverance volition usage to driblet its samples.

"You can't simply driblet them successful a large heap due to the fact that the betterment helicopters are designed to interact with lone 1 conduit astatine a time," Cook said.

The rover volition driblet the tubes successful an intricate zigzag layout, allowing for capable abstraction astir each driblet portion to marque definite the helicopters tin prime them up if necessary.

The Sample Retrieval Lander besides carries the Mars Ascent Vehicle — the archetypal rocket that volition ever motorboat from the Martian surface, with the samples tucked safely inside. The spacecraft is acceptable to motorboat from Mars successful 2031. A abstracted ngo volition motorboat from Earth successful the mid-2020s, called the Earth Return Orbiter, to rendezvous with the Mars Ascent Vehicle.

Onboard the Earth Return Orbiter is simply a strategy that volition cod the instrumentality of samples from the Mars Ascent Vehicle portion some vehicles are successful orbit astir the reddish planet.

The Earth Return Orbiter volition past caput backmost to our planet. Once the spacecraft is adjacent to Earth, it volition merchandise a conveyance containing the cache of samples, and that spacecraft volition interaction down connected Earth successful 2033.

Perseverance's aboriginal plans

Perseverance's premier ngo volition extremity connected January 6 — astir 2 years (and 1 Mars year) aft it landed connected the reddish planet. But the rover's travel isn't implicit yet.

"We volition inactive beryllium moving the illustration depot deployment erstwhile our extended ngo begins connected (January 7), truthful thing changes from that perspective," said Art Thompson, Perseverance's task manager astatine JPL, successful a statement. "However, erstwhile the array is acceptable astatine Three Forks, we'll caput to the apical of the delta. The subject squad wants to instrumentality a bully look astir up there."

Perseverance volition determination into its caller subject operations, called the Delta Top Campaign, successful the caller year. The rover volition decorativeness climbing the steep slope of an past stream delta that erstwhile emptied into Jezero Crater's water billions of years agone and get astatine the precocious aboveground of the delta successful February.

For the adjacent 8 months, Perseverance volition hunt for boulders and further worldly that the river may person carried from other parts of Mars and deposited astatine the delta.

"The Delta Top Campaign is our accidental to get a glimpse astatine the geological process beyond the walls of Jezero Crater," said Katie Stack Morgan, lawman task idiosyncratic for Perseverance astatine JPL, successful a statement.

"Billions of years agone a raging stream carried debris and boulders from miles beyond the walls of Jezero. We are going to research these past stream deposits and get samples from their long-traveled boulders and rocks."
