Curiosity's Daily Update: MSL Telemetry Monitoring, Trajectory Tracking Continue

July 27: MSL Telemetry Monitoring, Trajectory Tracking Continue
The flight team continues to monitor the Mars Science Laboratory spacecraft's telemetry and track its trajectory. There are no real-time spacecraft activities planned today. Late tomorrow night, the spacecraft is scheduled to perform its fourth and smallest trajectory correction maneuver, which will mark the beginning of MSL's final approach to Mars.

July 26: MSL Configured for Final Approach; Flight Team Takes a Breath
With completion of nearly all work to configure the Mars Science Laboratory spacecraft for entry, descent and landing, most of the flight team is getting some well-deserved rest today in preparation for next week's final approach to Mars. There are no planned flight team spacecraft activities today. NASA's Deep Space Network continues to monitor spacecraft telemetry and track the spacecraft's trajectory.

July 25: MSL's Terminal Descent Radar System Gets a Checkout
Today, the Mars Science Laboratory's terminal descent sensor is being checked out in preparation for Curiosity's entry, descent and landing. The sensor is a radar system that is mounted on MSL's descent stage. Following separation of MSL's heat shield at an altitude of approximately 5 miles (8 kilometers) and a velocity of approximately 280 mph (125 meters per second), the sensor begins collecting data on the spacecraft's velocity and altitude in preparation for landing.

July 24: Curiosity's Batteries Get a Charge
Today, Curiosity's two lithium ion rechargeable batteries are being recharged to 100 percent of capacity in preparation for entry, descent and landing. The batteries, which have been maintained at a 70-percent state of charge during the cruise to Mars, are being recharged using power from Mars Science Laboratory's cruise-stage solar array. The batteries enable Curiosity's power subsystem to meet peak power demands of rover activities when the demand temporarily exceeds the onboard multi-mission radioisotope thermoelectric generator (MMRTG) steady output level. With a capacity of about 42 amp-hours each, the batteries are expected to go through multiple charge-discharge cycles per Martian day.

July 23: Prepping MSL's Descent Stage Navigation System for Landing
Preparations continue for Curiosity's entry, descent and landing and surface operations. Today, the two inertial measurement units (IMUs) in Mars Science Laboratory's descent stage are being configured, along with other guidance and control parameters for entry, descent and landing. The IMUs are electronic devices that will be used to maneuver the spacecraft's descent stage, measuring and reporting on its velocity, orientation and gravitational forces. The descent stage does its main work during the final few minutes before touchdown on Mars, providing rocket-powered deceleration and two bands of telecommunications for the final phase of MSL's arrival at Mars that includes lowering the Curiosity rover on a bridle and continuing descent until rover touchdown. In addition, more communications parameter updates for Curiosity's surface operations are being uploaded to Curiosity's main computers.

July 22: Trajectory Tracking Continues
Engineers at NASA's Deep Space Network continue to run differential ranging track passes to track Mars Science Laboratory's trajectory. These activities are designed to more closely track the spacecraft's trajectory and position as it draws nearer to the Red Planet and Mars' gravitational influence on the spacecraft increases.

July 21: Getting a Better Bead on Trajectory
Today, engineers at NASA's Deep Space Network are running two differential ranging track passes to track Mars Science Laboratory's trajectory. These activities are designed to more closely track the spacecraft's trajectory and position as it draws nearer to the Red Planet and Mars' gravitational influence on the spacecraft increases.

Curiosity's Daily Update: Course Maneuver Successful; MSL Begins Final Approach

July 29: Course Maneuver Successful; MSL Begins Final Approach
Late Saturday night, NASA's Mars Science Laboratory spacecraft successfully fine-tuned its course to better zero in on its target entry point into the Martian atmosphere on landing day. Two brief thruster firings totaling about six seconds altered the spacecraft's velocity slightly, by about one-fortieth of one mile per hour (one centimeter per second). This trajectory correction maneuver the fourth since MSL's launch adjusted the point at which Curiosity will enter the Martian atmosphere by about 13 miles (21 kilometers). On landing day, MSL can steer enough during its flight through the upper atmosphere to correct for a miss of the target entry point by a few miles and still land within its target ellipse. Mission engineers and managers rated the projected 13-mile miss big enough to warrant a correction maneuver. Telemetry and tracking data indicate the maneuver was successful. MSL will have two further opportunities for additional course corrections during the final 48 hours before landing, if needed.

July 28: MSL Set to Begin Final Approach
Tonight the Mars Science Laboratory spacecraft is scheduled to perform a very small course adjustment, called Trajectory Correction Maneuver 4 (TCM-4). Around 10 p.m. PDT (1 a.m. EDT), two brief thruster firings totaling about six seconds will adjust the spacecraft's trajectory to better hone in on Curiosity's target entry point into the Martian atmosphere. This course adjustment will be the fourth performed during MSL's journey between Earth and Mars. The maneuver will turn the spacecraft to its final attitude and mark the start of Curiosity's final approach to the Red Planet.

Mars Science Lab fine-tunes path for rover landing

Firing its thrusters for a mere six seconds early Sunday, NASA's Mars-bound Curiosity rover added more precision to its flight path for a high-stakes entry, descent and landing next Monday morning.

It was one of six mid-course correction opportunities for the Mars Science Laboratory spacecraft since launching atop an Atlas 5 rocket on Nov. 26. Two more chances are available Saturday and Sunday, the last coming just 9 hours before landing.

Curiosity is headed a landing zone inside Gale Crater near the base of Mount Sharp where the rover will explore for two years (a full Martian year) to determine if the site was once habitable for life.

Touchdown is scheduled for 1:31 a.m. EDT (0631 GMT) next Monday, Earth-receive time.

Sunday's maneuver featured two brief firings at about 1 a.m. EDT to tweak the craft's planned atmospheric entry point by about 13 miles. Navigation tracking had indicated that without the burn MSL would have hit the top of the Martian atmosphere about 13 miles east of the target spot.

"The first look at telemetry and tracking data afterwards indicates the maneuver succeeded as planned," said Tomas Martin-Mur of NASA's Jet Propulsion Laboratory, chief of the mission's navigation team.

The accuracy is remarkable considering Curiosity will have traveled about 352 million miles on its 8-month interplanetary trek from Earth to Mars.

The thruster firings changed the 8,463-pound spacecraft's velocity by about one-fortieth of one mile per hour (one centimeter per second).

"I will not be surprised if this was our last trajectory correction maneuver," Martin Mur said of Sunday's burns. "We will be monitoring the trajectory using the antennas of the Deep Space Network to be sure Curiosity is staying on the right path for a successful entry, descent and landing."

Curiosity, packed within its protective descent pod, will enter Mars' atmosphere at a speed of about 13,200 mph (5,900 meters per second) and touch down on the red planet's surface at just 1.7 mph only seven minutes later. The heat shield, parachute and novel rocket-powered "sky crane" will work in sequence to slow the car-sized rover enough to set its wheels directly onto the ground at landing.

The mission's first two flight path corrections occurred on Jan. 11 and March 26 to put the spacecraft on a course to intercept Mars. They erased the deliberate, launch-induced miss of the planet by 25,000 miles so that the spent Centaur rocket body following Curiosity won't hit Mars.

The initial operation used 59 minutes of thruster firings, changing the craft's speed by 12.3 mph. The follow-up maneuver lasted 9 minutes and altered the velocity by 2 mph.

Another burn June 26 lasted 40 seconds to tweak the spacecraft's entry point by 125 miles and advanced that descent timing by 70 seconds, putting the vehicle on a course to hit the planet at the right place, angle and time.

In recent days, the flight batteries were topped to 100 percent via the cruise stage's solar arrays and engineers performed a final check of the descent sensor for tracking velocity and altitude during landing.

At the time of touchdown, Mars will be 154 million miles from Earth and the one-way communications time will be 13.8 minutes.

NASA's Mars Odyssey spacecraft has successfully adjusted its orbital location to be in a better position to provide prompt confirmation of the August landing of the Curiosity rover.

NASA's Mars Science Laboratory spacecraft carrying Curiosity can send limited information directly to Earth as it enters Mars' atmosphere. Before the landing, Earth will set below the Martian horizon from the descending spacecraft's perspective, ending that direct route of communication. Odyssey will help to speed up the indirect communication process.

NASA reported during a July 16 news conference that Odyssey, which originally was planned to provide a near-real-time communication link with Curiosity, had entered safe mode July 11. This situation would have affected communication operations, but not the rover's landing. Without a repositioning maneuver, Odyssey would have arrived over the landing area about two minutes after Curiosity landed.

Марсоход выполнил еще один маневр на пути к Марсу[/size]

Аппарат MSL, на борту которого находится одноименный марсоход, совершил, вероятно, последний маневр перед посадкой на Красную планету. Об этом сообщается на официальном сайте проекта.

 Маневр был относительно небольшой - ускорители аппарата включились дважды в общей сложности на шесть секунд. В сообщении говорится, что это позволило передвинуть точку входа аппарата в марсианскую атмосферу на 21 километр. Поправка курса стала четвертой по счету с момента запуска космического аппарата.

 Инженеры говорят, что в последние 48 часов полета, когда окончательно станут известны параметры входа корабля в атмосферу, у них будет еще две возможности подправить курс, если потребуется. Кроме того, такая же возможность будет уже непосредственно во время спуска.

 Марсоход MSL, известный также как "Любопытство" (Curiousity), стартовал к Красной планете 26 ноября 2011 года. Планируется, что на место аппарат прибудет 6 августа 2012 года. Обратный отсчет до посадки можно найти здесь.

 Целью космического аппарата является кратер Гейла. Это образование диаметром свыше 160 километров, в центре которого расположена многокилометровая насыпь. Ученые считают, что эта насыпь - осадочные породы, принесенные в кратер еще тогда, когда на Марсе была вода.

 MSL не только проверит эту гипотезу, но и займется поисками следов жизни и изучением геологической истории Марса в целом. Для этих нужд марсоход оборудован множеством приборов, среди которых четыре спектрометра, а также российский прибор DAN для изучения "нейтронного альбедо" марсианской поверхности. Он необходим для поиска залежей льда.
