Curiosity's Daily Update: MSL Right on Course -- TCM-5 Cancelled

Aug. 3: MSL Right on Course -- TCM-5 Cancelled
With less than three days to go before touchdown on the Red Planet, Curiosity remains in good health, with all systems operating as expected. Given the Mars Science Laboratory spacecraft's consistent and stable course, today the project decided that the planned Trajectory Correction Maneuver 5 (TCM-5) and its corresponding update to parameters for the autonomous software controlling events during entry, descent and landing will not be necessary. As of 12:35 p.m. today PDT (3:35 p.m. EDT), the Mars Science Laboratory spacecraft was approximately 468,000 miles (753,200 kilometers) from Mars, or a little less than twice the distance from Earth to the moon. It is traveling at about 8,000 mph (3,576 meters per second). It will gradually increase in speed to about 13,200 mph (5,900 meters per second) by the time it reaches the top of the Martian atmosphere.

Aug. 2: MSL Remains on Track for Weekend Landing
Curiosity remains in good health, with no significant issues currently in work. There are no real-time activities planned today. The Mars Science Laboratory spacecraft remains on a consistent and stable course, well within the limits required to reach its target landing ellipse. As a result, yesterday the flight team decided to cancel the build and test of a contingency version of Trajectory Correction Maneuver 5. This contingency manuever, had it been needed, would have been used in the event an emergency prevented the team from executing the nominal scheduled TCM-5 maneuver, which is planned for Friday, Aug. 3, if needed. The project also canceled a corresponding update to parameters for the autonomous software controlling events during entry, descent and landing.

Aug. 1: Further Preps for Entry, Descent and Landing
With Curiosity now flying under the control of the autonomous entry, descent and landing timeline, the Mars Science Laboratory team continues to monitor the spacecraft's health and trajectory. There are no real-time activities planned today. In the event that a fifth trajectory correction maneuver is needed to further fine-tune the spacecraft's course to reach its target landing ellipse, the flight team is making preparations for it. If needed, that maneuver would be executed on Friday, Aug. 3. Curiosity remains in good health, with no significant issues currently in work.

July 31: Entry, Descent and Landing Timeline Activated
The Mars Science Laboratory continues its final preparations for entry, descent and landing this upcoming weekend. Yesterday, the flight team completed and confirmed a memory test on the software for the mechanical assembly that controls MSL's descent motor. They also configured the spacecraft for its transition to entry, descent and landing approach mode, and they enabled the spacecraft's hardware pyrotechnic devices. MSL is now under the control of the autonomous entry, descent and landing timeline flight software. The flight team continues to monitor Curiosity's onboard systems and flight trajectory. The spacecraft and ground systems remain in good health, with no significant issues currently being worked.

What to Expect When Curiosity Starts Snapping Pictures

If a group of tourists piled out of a transport vehicle onto the surface of Mars, they'd no doubt start snapping pictures wildly. NASA's Curiosity rover, set to touch down on the Red Planet the evening of Aug. 5 PDT (early morning EDT), will take a more careful approach to capturing its first scenic views.

The car-size rover's very first images will come from the one-megapixel Hazard-Avoidance cameras (Hazcams) attached to the body of the rover. Once engineers have determined that it is safe to deploy the rover's Remote Sensing Mast and its high-tech cameras, a process that may take several days, Curiosity will begin to survey its exotic surroundings.

"A set of low-resolution gray scale Hazcam images will be acquired within minutes of landing on the surface," said Justin Maki of NASA's Jet Propulsion Laboratory in Pasadena, Calif. "Once all of the critical systems have been checked out by the engineering team and the mast is deployed, the rover will image the landing site with higher-resolution cameras."

Maki led the development of Curiosity's 12 engineering cameras -- eight Hazcams at the front and back of the rover, and four Navigation cameras (Navcams) at the top of the rover's "look-out" mast. All the engineering cameras acquire black-and-white pictures from left and right stereo "eyes," which are merged to provide three-dimensional information. Half of the cameras are backups, meaning there's one set for each of the rover's A- and B-side redundant computers.

The very first images are likely to arrive more than two hours after landing, due to the timing of NASA's signal-relaying Odyssey orbiter. They will be captured with the left and right Hazcams at the back and front of the rover, and they will not yet be full-resolution (the two images arriving on Earth first are "thumbnail" copies, which are 64 by 64 pixels in size). The Hazcams are equipped with very wide-angle, fisheye lenses, initially capped with clear dust covers. The covers are designed to protect the cameras from dust that may be kicked up during landing; they are clear just in case they don't pop off as expected.

These first views will give engineers a good idea of what surrounds Curiosity, as well as its location and tilt. "Ensuring that the rover is on stable ground is important before raising the rover's mast," said Mission Manager Jennifer Trosper at JPL. "We are using an entirely new landing system on this mission, so we are proceeding with caution."

Color pictures from the rover's Mars Descent Imager, or MARDI, acquired as the rover descends to the Martian surface, will help pinpoint the rover's location. Initial images from MARDI are expected to be released Aug. 6, the day after landing. These will also be in the form of thumbnails (in the case of the science cameras, thumbnails can vary in size, with the largest being 192 pixels wide by 144 pixels high). One full-resolution image may also be returned at this time.

Additional color views of the planet's surface are expected the morning of Aug. 7 from the Mars Hand Lens Imager, or MAHLI, one of five devices on the rover's Inspector Gadget-like arm. The camera is designed to take close-up pictures of rocks and soil, but can also take images out to the horizon. When Curiosity lands and its arm is still stowed, the instrument will be pointed to the side, allowing it to capture an initial color view of the Gale Crater area.

Once Curiosity's mast is standing tall, the Navcams will begin taking one-megapixel stereo pictures 360 degrees around the rover as well as images of the rover deck. These cameras have medium-angle, 45-degree fields of views and could resolve the equivalent of a golf ball lying 82 feet (25 meters) away. They are designed to survey the landscape fairly quickly, and, not only can they look all around but also up and down. Navigation camera pictures are expected to begin arriving on Earth about three days after landing if the mast is deployed on schedule.

Like the Hazcams, Navcam images are used to obtain three-dimensional information about the Martian terrain. Together, they help the scientists and engineers make decisions about where and how to drive the rover and which rocks to examine with instruments that identify chemical ingredients. "A large part of the surface mission is conducted using the images returned from the cameras," said Maki.

Also, about three days after landing, the narrower field-of-view Mast Cameras (Mastcams) are expected to start snapping their first shots. These two-megapixel color cameras will reveal the rover's new home in exquisite detail. Small thumbnail versions of the pictures will be sent down first with an initial high-resolution panorama expected more than a week later.

The camera of the Chemistry and Camera (ChemCam) instrument will provide a telescopic view of targets at a distance.

As the mission progresses, the entire suite of cameras and science instruments will work together to hunt for clues to the mystery of Mars and help answer the long-standing puzzle of whether our next-door-neighbor planet has ever offered environmental conditions favorable for microbial life.

Она уже есть: см. ссылку выше. :wink:

Ну, eyes.nasa.gov же все-таки не по телеметрии строится изображение. Кстати, Марс там со вчерашнего дня подрос в размерах. Совсем недолго осталось!

[pkl]

Да там телеметрия и не требуется; баллистика - наука точная. :wink:

Зато как наглядно! Там и место посадки можно посмотреть - его MRO отснял. А по интернет каналам одни конференции идут.

[Dude]

Да, лучше всё-таки трансляцию смотреть.
На пресс-конференции пообещали, что Алан Чен будет комментировать и читать из телеметрии сообщения EVR...

[testest]

Ну вот, а я думаю, что во время посадки что-то вроде этого будет, но по ТМИ, вряд ли будут фотографии с борта. Хотя как бы хотелось!
Осталось 470 000 км.

[Dude]

Как я понял для прямой трансляции будут использоваться два источника:
- до выхода парашюта, и немного после, будут идти EVR в Х-диапазоне c КА прямо в DSN, потом Земля зайдет за горизонт.
- Марс Одиссей будет принимать УКВ и ретранслировать в DSN.

MRO будет работать на запись в УКВ и фотографировать спуск, но увидеть результаты съемки можно будет только через сутки,  запись телеметрии через 2 часа после посадки.

Марс Экспресс, будет записывать несущую, но данных не ожидается. (!?)

[Старый]

Вобщем кина не будет.
 Скажите окончательно: во сколько по московскому ожидается получение сообщения о посадке?
