Curiosity MSL (Mars Science Laboratory) - Atlas V 541 - Canaveral SLC-41 - 26.11.2011

[instml]

До посадки на Марс всего несколько часов

Все системы MSL работают хорошо, траектория правильна. Шестая коррекция траектории отменена за ненадобностью. Межпланетному автомату предстоит совершить один из сложнейших подвигов в истории исследования космоса.

Mission Manager Brian Portock of JPL: "Мы волнуемся, но мы считаем, что мы очень хорошо подготовлены".

Позже сегодня, будет сделан выбор, следует ли обновить бортовую информацию, используемую во время автономного управления процедурой EDL. Планируется, что транслировать на Землю в режиме реального времени данные с MSL о критическом этапе посадки будет Марс Одиссей. Если по какой-то причине Марс Одиссей не сможет обеспечить такую трансляцию, узнать о результате можно будет лишь через два с лишним часа. На первой картинке схематично изображены способы передачи данных с MSL: розовенькие волны - тоновый сигнал на Землю в X-диапазоне, голубенькие волны - УКВ-сигнал на иск. спутники Марса.

Curiosity Rover Just Hours from Mars Landing

Mars Science Laboratory Mission Status Report

PASADENA, Calif. -- NASA's Mars Science Laboratory spacecraft is healthy and right on course for a landing in several hours that will be one of the most difficult feats of robotic exploration ever attempted.

Emotions are strong in the control room at NASA's Jet Propulsion Laboratory, Pasadena, Calif., as the hours and miles race toward touchdown of the car-size Curiosity at about 10:31 p.m. PDT tonight (about 1:31 a.m. Aug. 6, EDT).

"Excitement is building while the team is diligently monitoring the spacecraft," said Mission Manager Brian Portock of JPL. "It's natural to get anxious before a big event, but we believe we are very well prepared."

Descent from the top of Mars' atmosphere to the surface will employ bold techniques enabling use of a smaller target area and heavier 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 this mission of discovery.  The same innovations advance NASA toward capabilities needed for human missions to Mars.

Controllers decided Sunday morning to forgo the sixth and last opportunity on the mission calendar for a course-correction maneuver.  The spacecraft is headed for its target entry point at the top of Mars' atmosphere precisely enough without that maneuver.

Later today, mission controllers will choose whether or not to use a last opportunity for updating onboard information the spacecraft will use during its autonomous control of the entry, descent and landing. Parameters on a motion tracker were adjusted Saturday for fine-tuning determination of the spacecraft's orientation during the descent.

At the critical moment of Curiosity's touchdown, controllers and the rest of the world will be relying on NASA's Mars Odyssey orbiter to provide immediate confirmation of a successful landing. Odyssey will turn to point in the right direction beforehand to listen to Curiosity during the landing. If for any reason that turn maneuver does not work, a successful landing cannot be confirmed until more than two hours later.

The landing will end a 36-week flight from Earth and begin at two-year prime mission on Mars. Researchers will use Curiosity's 10 science instruments to investigate whether Martian environmental conditions have ever been favorable for microbial life.

JPL, a division of the California Institute of Technology in Pasadena, manages the mission for the NASA Science Mission Directorate, Washington.

Надо искать запасные варианты, на случай падения сайта , уже сейчас.

Go MSL!  Go MSL!  Go MSL!  Тпру-у-у!!! Впереди Марс ...

Newest NASA Mars Mission Connects Past and Future
08.02.12

PASADENA, Ca. -- NASA's newest Mars mission, landing in three days, will draw on support from missions sent to Mars years ago and will contribute to missions envisioned for future decades.

"Curiosity is a bold step forward in learning about our neighboring planet, but this mission does not stand alone. It is part of a sustained, coordinated program of Mars exploration," said Doug McCuistion, director of the Mars Exploration Program at NASA Headquarters in Washington. "This mission transitions the program's science emphasis from the planet's water history to its potential for past or present life."

As the Mars Science Laboratory spacecraft places the Curiosity rover on the surface of Mars next week, NASA will be using the Mars Odyssey orbiter, in service since 2001, as a relay for rapidly confirming the landing to Curiosity's flight team and the rest of the world. Earth will be below the Mars horizon from Curiosity's perspective, so the new rover will not be in direct radio contact with Earth. Two newer orbiters also will be recording Curiosity's transmissions, but that data will not be available on Earth until hours later.

When Curiosity lands beside a mountain inside a crater at about 10:31 p.m. PDT, Aug. 5 (1:31 a.m. EDT Aug. 6), the 1-ton rover's two-year prime mission on the surface of Mars will begin. However, one of the rover's 10 science instruments, the Radiation Assessment Detector, or RAD, already has logged 221 days collecting data since the spacecraft was launched on its trip to Mars on Nov. 26, 2011.

"Our observations already are being used in planning for human missions," said Don Hassler of Southwest Research Institute in Boulder, Colo., principal investigator for Curiosity's RAD.

The instrument recorded radiation spikes from five solar flare events spewing energetic particles from the sun into interplanetary space. Radiation from galactic cosmic rays, originating from supernova explosions and other extremely distant events, accounted for more of the total radiation experienced on the trip than the amount from solar particle events. Inside the spacecraft, despite shielding roughly equivalent to what surrounds astronauts on the International Space Station, RAD recorded radiation amounting to a significant contribution to a NASA astronaut's career-limit radiation dose.

Curiosity's main assignment is to investigate whether its study area ever has offered environmental conditions favorable for microbial life. To do that, it packs a science payload weighing 15 times as much as the science instruments on previous Mars rovers. The landing target, an area about 12 miles by 4 miles (20 kilometers by 7 kilometers), sits in a safely flat area between less-safe slopes of the rim of Gale Crater and the crater's central peak, informally called Mount Sharp. The target was plotted to be within driving distance of layers on Mount Sharp, where minerals that formed in water have been seen from orbit.

"Some deposits right inside the landing area look as though they were deposited by water, too," said John Grotzinger of the California Institute of Technology (Caltech) in Pasadena, project scientist for Curiosity. "We have a great landing site that was a strong science contender for earlier missions, but was not permitted for engineering constraints because no earlier landing could be targeted precisely enough to hit a safe area inside Gale Crater. The science team feels very optimistic about exploration of Mount Sharp and the surrounding region that includes the landing ellipse."

Mission engineers designed a sky crane maneuver, lowering Curiosity on nylon cords from a rocket backpack because the rover is too heavy to use the airbag system developed for earlier rovers. "We know it looks crazy," said Adam Steltzner of NASA's Jet Propulsion Laboratory (JPL) in Pasadena, leader of the team that developed the system. "It really is the result of careful choices." By designing the aeroshell enclosing Curiosity to create lift and be steerable, engineers were able to build a system that lands much more precisely instead of dropping like a rock.

смотрю сегодняшний брифинг НАСА по записи. Говорят первые фото будут уже  4 минуты после посадки.

[pkl]

там кто нибудь встречать будет?   : )

А как же! Его целых три орбитера давно уже поджидают!

[Дмитрий Виницкий]

А, я, блин, во время посадки, в ЗАГСЕ буду заявление подавать...

Да ну? Как я понял, они сначала будут с HGA возиться. Телеметрию снимать. Первые снимки /умеренного разрешения/ будут в середине дня, не раньше. С hazcam'ов. А "голову" с основными камерами поднимут только послезавтра.

[Дмитрий Виницкий]

С Mars Descent Imager (MARDI), очевидно.

речь про HAZCAM's Thumbnails (64x64 subsampled resolution), linearized, если всё ОК будут получены, через ретрансляцию с Марс Одиссей, по-сути это иконки для фото даже для этой слабой камеры.
