Этот спор уже был.
Закончился тем, что я предложил Хлынину пригласить Дмитрия для вскапывания реголита на огород.

"Космический аппарат MRO (Mars Reconnaissance Orbiter) сделал потрясающий снимок пылевого вихря на поверхности Марса. Запечатленный на фотографии огромный крутящийся столб пыли составлял в высоту около 800 метров. Камера высокого разрешения HiRISE сделала это изображение 16 февраля 2012 года, когда космический аппарат MRO пролетал над областью, носящей название "равнина Амазония". В этой области можно наблюдать следы многих других вихрей, или пылевых смерчей, в виде полос на пыльной поверхности Марса.
   Так же, как и на Земле, сила ветров на Марсе зависит от солнечного тепла. Сейчас Марс находится далеко от солнца, в этом положении воздействие солнечных лучей значительно ниже. Однако, даже не смотря на это, на поверхности Марса можно наблюдать мощные штормы.
   Подобные смерчи образуются и на Земле. Это вращающиеся столбы воздуха, видимые за счет поднимаемой пыли. В отличие от торнадо, смерчи обычно образуются в ясную погоду. Когда земля сильно разогревается Солнцем и нагревает воздух над собой. Разогретый воздух быстро поднимается вверх по небольшому каналу холодного воздуха, и при определенных условиях начинает вращаться."

Mars-Bound NASA Craft Adjusts Path, Tests Instruments

Mars Science Laboratory Mission Status Report

PASADENA, Calif. -- NASA's Mars Science Laboratory spacecraft, halfway to Mars, adjusted its flight path today for delivery of the one-ton rover Curiosity to the surface of Mars in August.

Tests completed aboard Curiosity last week confirmed the health of science instruments the mission will use to learn whether an area holding an extensive record of Martian environmental history has ever offered conditions favorable for microbial life.

In the second of six planned trajectory correction maneuvers during the cruise to Mars, the spacecraft ignited thrusters for nearly nine minutes today. Spacecraft data and Doppler-effect changes in radio signal from the craft, monitored in the mission control room at NASA's Jet Propulsion Laboratory, Pasadena, Calif., indicate the maneuver succeeded.

"It is satisfying to get the second maneuver under our belts and know we are headed in the right direction," said JPL's Erisa Hines, systems lead for the maneuver. "The cruise system continues to perform very well."

"We are now on a trajectory that will put us much closer to the point we want to hit on Aug. 5," added Tomas Martin-Mur, navigation team chief for the mission.

The halfway point of the trip from Earth to Mars will be April 1, in terms of duration. The mission launched Nov. 26, 2011. It will land the evening of Aug. 5, 2012, PDT (early Aug. 6, EDT and Universal Time).

One of Curiosity's 10 science instruments, the Radiation Assessment Detector (RAD) has been collecting data for three months, monitoring the natural radiation environment in interplanetary space. This information, particularly effects RAD has measured from recent solar flares, is crucial for design of human missions to Mars.

In the past two weeks, the rover team has checked the status of the other nine of Curiosity's science instruments, powering them on for the first time since before launch. All the instruments passed these checkouts.

"The types of testing varied by instrument, and the series as whole takes us past the important milestone of confirming that all the instruments survived launch," said Betina Pavri of NASA's Jet Propulsion Laboratory, Pasadena, Calif., science payload test engineer for the mission. "These checkouts provide a valuable calibration and characterization opportunity for the instruments, including camera dark images and a measurement of zero pressure in the vacuum of space for the rover weather station's pressure sensor."

Curiosity's landing site is near the base of a mountain inside Gale Crater, near the Martian equator. Researchers plan to use Curiosity to study layers in the mountain that hold evidence about wet environments of early Mars.

First, the spacecraft must get there. Today's maneuver nudged the spacecraft one-seventh as much as the flight's first course adjustment, on Jan. 11. After the first maneuver, the trajectory would have put Curiosity about 3,000 miles (5,000 kilometers) and 20 minutes away from entering Mars' atmosphere at the right place and time. Like that maneuver, today's combined two ways of using thruster engines while the whole spacecraft spins at two rotations per minute.

The spacecraft's cruise stage carries eight thrusters grouped into two sets of four. The maneuver began with about three minutes of firing one thruster in each set to change velocity along the direction of the axis of rotation. Then, to push the spacecraft in a direction perpendicular to the axis, each set of thrusters was used for five-second pulses when the spacecraft's rotation put that set at the correct orientation. The maneuver used more than 60 of these pulses spaced about 10 seconds apart.

"The purpose is to put us on a trajectory to the point in the Mars atmosphere where we need to be for a safe and accurate landing," said Mau Wong, maneuver analyst at JPL.

The descent from the top of Mars' atmosphere to the surface will employ bold techniques enabling use of a smaller target area and larger landed payload than were possible for any previous Mars mission. These innovations, if successful, will place a well-equipped mobile laboratory into a locale especially well suited for its mission of learning. The same innovations advance NASA toward capabilities needed for human missions to Mars.

As of March 29, the spacecraft will have traveled about 196 million miles (316 million kilometers) of its 352-million-mile (567-million-kilometer) flight to Mars.

'Mount Sharp' On Mars Links Geology's Past and Future

Curiosity, the big rover of NASA's Mars Science Laboratory mission, will land in August 2012 near the foot of a mountain inside Gale Crater. Image credit: ASA/JPL-Caltech/ESA/DLR/FU Berlin/MSSS

One particular mountain on Mars, bigger than Colorado's grandest, has been beckoning would-be explorers since it was first sighted from orbit in the 1970s. Scientists have ideas about how it took shape in the middle of ancient Gale Crater and hopes for what evidence it could yield about whether conditions on Mars have favored life.

No mission to Mars dared approach it, though, until NASA's Mars Science Laboratory mission, which this August will attempt to place its one-ton rover, Curiosity, at the foot of the mountain. The moat of flatter ground between the mountain and the crater rim encircling it makes too small a touchdown target to have been considered safe without precision-landing innovations used by this mission.



To focus discussions about how Curiosity will explore the mountain during a two-year prime mission after landing, the mission's international Project Science Group has decided to call it Mount Sharp. This informal naming pays tribute to geologist Robert P. Sharp (1911-2004), a founder of planetary science, influential teacher of many current leaders in the field, and team member for NASA's first few Mars missions. Sharp taught geology at the California Institute of Technology (Caltech), in Pasadena, from 1948 until past his retirement. Life magazine named him one of the 10 best college teachers in the nation.

"Bob Sharp was one of the best field geologists this country has ever had," said Michael Malin, of Malin Space Science Systems, San Diego, principal investigator for two of Curiosity's 10 science instruments and a former student of Sharp's.

"We don't really know the origins of Mount Sharp, but we have plans for how to go there and test our theories about it, and that's just how Bob would have wanted it," Malin said.

Caltech Provost Edward Stolper, former chief scientist for the Mars Science Laboratory, said, "For much of his more than 50 years at Caltech, Bob Sharp was the central figure in its programs in the geological and planetary sciences. One of his major contributions was the building of a program in planetary sciences firmly rooted in the principles and approaches of the geological sciences.

"Moreover, through his own work on the Jet Propulsion Laboratory's early missions to Mars and the work of others that he influenced, he also had a major influence on planetary science and exploration at JPL. Recognition of this remarkable scientist and leader by the naming of Mount Sharp is highly fitting, and I hope it will serve to perpetuate his legacy."

The Mars Science Laboratory spacecraft was launched Nov. 26, 2011, bound for landing beside Mount Sharp inside Gale Crater on the evening of Aug. 5, PST (early Aug. 6, EST and Universal Time). The mission will use Curiosity to investigate whether the area has ever offered environmental conditions favorable for fostering microbial life, including chemical ingredients for life and energy for life.

Mount Sharp rises about 3 miles (5 kilometers) above the landing target on the crater floor, higher than Mount Rainier above Seattle, though broader and closer. It is not simply a rebound peak from the asteroid impact that excavated Gale Crater. A rebound peak may be at its core, but the mountain displays hundreds of flat-lying geological layers that may be read as chapters in a more complex history billions of years old.

Twice as tall as the sequence of colorful bands exposed in Arizona's Grand Canyon, the stack of layers in Mount Sharp results from changing environments in which layers are deposited, younger on top of older, eon after eon, and then partially eroded away.

Several craters on Mars contain mounds or mesas that may have formed in ways similar to Mount Sharp, and many other ancient craters remain filled or buried by rock layers. Some examples, including Gale, hold a mound higher than the surrounding crater rim, indicating that the mounds are remnant masses inside once completely filled craters. This presents a puzzle about how environmental conditions on Mars evolved.

"This family of craters that were filled or buried and then exhumed or partially exhumed raises the question of what changed," said Ken Edgett of Malin Space Sciences, principal investigator for one of Curiosity's instruments. "For a long time, sedimentary materials enter the crater and stay. Then, after they harden into rock, somehow the rock gets eroded away and transported out of the crater."

Some lower layers of Mount Sharp might tell of a lake within Gale Crater long ago, or wind-delivered sediments subsequently soaked by groundwater. Orbiters have mapped water-telltale minerals in those layers. Liquid water is a starting point in describing conditions favorable for life, but just the beginning of what Curiosity can investigate. Higher layers may be deposits of wind-blown dust after a great drying-out on Mars.

"Mount Sharp is the only place we can currently access on Mars where we can investigate this transition in one stratigraphic sequence," said Caltech's John Grotzinger, chief scientist for the Mars Science Laboratory. "The hope of this mission is to find evidence of a habitable environment; the promise is to get the story of an important environmental breakpoint in the deep history of the planet. This transition likely occurred billions of years ago -- maybe even predating the oldest well-preserved rocks on Earth."

Possible explanations for how erosion shaped the mountain after layers were deposited include swirling winds carving away the edges, and perhaps later wet episodes leaving channels down the sides and fresher sediments on the crater floor. Clues about those episodes present Curiosity with other potentially habitable environments to investigate.
