India putting final touches on Mars-bound spacecraft
http://www.spaceflightnow.com/news/n1310/07isromars/

India's first Mars probe is preparing for launch in late October on a trial run to the red planet to lay the technological foundation for future Indian deep space missions.

Set for liftoff as soon as Oct. 28, the Mars Orbiter Mission will demonstrate deep space navigation and communications, interplanetary travel, spacecraft autonomy, and the complex make-or-break rocket burn to place the spacecraft in orbit around Mars.

Only the United States, Russia and the European Space Agency have successfully dispatched robots to Mars before. The Indian Space Research Organization hopes to be the fourth space agency to accomplish the feat.

The Indian orbiter also carries a small camera to return medium-resolution color imagery of the Martian terrain, a thermal infrared spectrometer to measure the chemical composition of the surface, and instruments to assess the Mars atmosphere, including a methane detector.

But Indian officials rank the orbiter's technological objectives higher than its science goals, according to J.N. Goswami, director of ISRO's Physical Research Laboratory and a top scientist on the Mars Orbiter Mission.

Goswami gave a briefing on the mission in March at the Lunar and Planetary Science Conference in Houston.

Engineers put together the Mars Orbiter Mission in quick time. Goswami said ISRO approved the mission in August 2011, with all the hardware assembled on the orbiter in less than two years.



Designers based the spacecraft on the Chandrayaan 1 lunar orbiter, which India successfully placed in orbit around the moon in November 2008 and successfully operated until August 2009.

The $73 million Mars Orbiter Mission has a launch window opening Oct. 28 and extending through Nov. 19.

The Jet Propulsion Laboratory is providing communications and navigation support for the mission, which requires the use of NASA's Deep Space Network, a set of three tracking stations in California, Spain and Australia.

Indian scientists last week feared the partial shutdown of the U.S. government - caused by political wrangling in Washington - could threaten India's access to NASA's tracking and navigation expertise.

"NASA/JPL authorities have reaffirmed support for the Mars Orbiter Mission as planned and stated that the current U.S. government partial shutdown will not affect the schedule of Mars Orbiter Mission," ISRO said in a statement released Saturday.

The spacecraft arrived at the Satish Dhawan Space Center on India's east coast Thursday after an overland trip from its factory and test facility in Bangalore.

Over the next three weeks, technicians will add rocket fuel to the spacecraft, which is about the size of a compact car. Then engineers will hoist the 2,976-pound probe atop an amped-up version of India's Polar Satellite Launch Vehicle called the PSLV XL.

Boosted by enlarged strap-on rocket motors, the PSLV will hurl the Mars-bound spacecraft into an elliptical loop with a peak altitude about 14,300 miles above Earth.

The Mars Orbiter Mission will propel itself out of the grasp of Earth's gravity with six engine burns, concluding the escape maneuvers around Nov. 30 and embarking on a 10-month interplanetary cruise to the red planet.

Arrival at Mars is scheduled for Sept. 21, 2014, one day before the arrival NASA's MAVEN Mars orbiter, which is on track for launch directly to Mars from Florida on Nov. 18.

The Indian spacecraft will enter an orbit ranging in altitude from 234 miles to nearly 50,000 miles above Mars, completing a lap around the planet every 3.2 days.

Пока одни "оптимизируют" и "реформируют" отрасль, другие менее чем за два года марсианский орбитер делают за скромную сумму...
 Молодцы, индусы! Очень надеюсь, что все у них получится.

Какая сумма - такой и орбитер.

Это понятно. Но у нас даже такого нет. Никто ведь не запрещает сделать простую технологическую АМС для отработки отдельных узлов, двигательной установки и отправить ее хоть к астероиду, хоть орбитером на Марс. Ничего нет! Одни обещания и картинки

ИМХО, польза от российской ПН на ExoMars TGO,гораздо больше чем от этого флаговтыка. Другое дело, что мы при этом не приобретаем опыта в изготовлении платформы и в работе с АМС вообще, но уж надо определится - либо миссия для накопления опыта, либо для науки. Если второе, то лучше не рисковать. Т.е. для накопления опыта у нас есть "Луна-Глоб-1", для науки - все остальное.

Луна-Глоб-1 из другой оперы. Она для мягкой посадки на Луну. К тому же в единственном экземпляре. Даже у американцев были легкие технологические АМС - тот же Dip Space 1, например. Чего мы так боимся простых миссий?

Ну, это действительно плохо. Но вроде есть МКА-ФКИ, Резонанс, Ионосфера - вроде простые миссии.
Другое дело, что никаких особых технологий на них не отрабатывается, но опыт эксплуатации научных КА все же приобретается.

India, US orbiters to reach Mars within 24 hours of each other
Paul John & Parth Shastri, TNN | Oct 19, 2013, 01.43 AM IST


Isro is buzzing with activity - not just for MOM but also for a slew of projects, scheduled for the next five years.

AHMEDABAD: Five years ago India launched its first successful Moon mission, Chandrayaan I. Now, with Mangalyaan, India will become the fourth nation in the world to take the first step to Mars, if it successfully positions a spacecraft in the red planet's orbit.

 As the countdown to India's maiden Mangalyaan, Mars Orbiter Mission (MOM) begins, Dr A S Kiran Kumar, director of Space Applications Center (SAC) of Indian Space Research Organization (Isro) provided a glimpse into the mission, the challenges his team faced and how India's "affordable" mission, has several dimensions -conducting scientific experiments, demonstrating technological capabilities and creating the necessary credentials to be part of future international space missions.

 Importance of the project

 The earliest attempts for exploration of the red planet began in 1960s at the height of 'space race' between US and the USSR when a number of missions were planned. The first mission was USSR's Marsnik 1 in October 1960 which failed to reach even the Earth's orbit. The US's Mariner 4 in November 1965 provided the first glimpse of the Martian surface during its fly-by mission. Since then, there have been a number of missions to probe the red planet, primarily by US' Nasa, including two rovers - Pathfinder and Curiosity - that have provided a full map of the planet and information of its atmosphere, soil composition and other aspects.

 What does Mangalyaan intend to achieve?

 "This is primarily a technological mission, considering its stringent precision requirements. The challenge before Isro is to put the spacecraft into a precise 50 km imaginary cube when it enters Mars gravitational field, around 250 million km away, while scientists control its 11-month journey and orientation. It requires a proper design, planning, management and operations," says Kumar.

 Technological challenges

 "On August 15, last year Prime Minister Manmohan Singh announced India's intention to send an orbiter to Mars. In 14 months, Isro was ready with an orbiter craft. The only experience Isro has with a mission to another celestial body is Chandrayaan I to the Moon," says Kumar. Other space powers - US, Russia and European Space Agency (ESA) - have, independently or in collaboration, conducted a number of experiments providing them chances to improvise. India is going with it's trusted PSLV-XL launcher which was used for Chandrayaan, albeit with modifications.

 The task

 "We sent Chandrayaan-1 to the Moon which was at a distance of 384,000 km, a challenge before us five years ago. It has been multiplied 1,000 times with the Mangalyaan mission, as we are now going 360,000,000 km away fr om Earth. Till Chandrayaan, we were concerned with Earth's gravity. For the first time, our probe will leave the Earth's influence, enter the Heliosphere - the region dominated by the Sun's gravity - before it enters Mar's gravitational field. The maximum Earth to Mars roundtrip light time (RLT) will be 42 minutes during the mission, meaning the signal (command) we send fr om Earth will reach the craft 21 minutes later and will take the same time for us to receive it back. Thus, we need to give a bit of autonomy to the craft to address emergencies," says Kumar. In order to take advantage of the window when the craft can reach Mars using minimum fuel, India has chosen October 28 this year. Such an opportunity comes at intervals of about 780 days.

 Challenges ahead

 It will be a 300-day journey for the craft in three phases - Geo-centric phase, Helio-centric phase and finally the nail-biting Martian phase-which will be around 573,000 km from Earth's surface.

 "If we don't propel the craft enough, it will fall into a circular orbit and eventually crash on the Martian surface. If we propel it too much, it will go away from the planet and be lost in space. We have designed an elliptical orbit for the craft wh ere the nearest distance will be 364 km and the farthest 80,000 km. Such an orbit will provide a unique opportunity to observe Mars from a distance wh ere the planet will rotate on its axis and we will be able to capture most of its surface barring some polar areas," Kumar says.

 He adds that they have subjected the payload and instruments to intense testing. "A craft encounters a number of issues while in space. While communication is always a concern, another issue is energy from the solar panels. As the craft encounters blackouts -periods in the shadow of the planet and can't receive energy - there are also periods of white-outs when the craft is bombarded with solar plasma and can't function for a while. We have taken such instances in consideration," he says.

 At Mars

 The craft is scheduled to reach the Mars orbit on September 21, 2014. There are five payloads on board including a Lyman Alpha Photometer, Methane Sensor for Mars, Mars Exospheric Neutral Composition Analyser, Mars Colour Camera and Thermal Infrared Imaging Spectrometer.

 The road ahead

 Isro is buzzing with activity - not just for MOM but also for a slew of projects, scheduled for the next five years. Kumar says that a successful Mars mission will not only boost India's confidence but also open doors for next-generation technology which will help future space endeavours. After Mangalyaan, ISRO is planning Chandrayaan II which will have a rover to collect and analyze samples from the lunar surface. India is also planning to launch its first dedicated astronomy satellite - ASTROSAT - after which the ambitious Aditya project will come into action. The project intends to study Coronal Mass Ejection (CME) from L1, one of the Lagrangian points between Sun and Earth which will facilitate the craft's remaining at the same position with least effort, for the observation.

 About manned space missions, Kumar says it would be the next logical step. "We are slowly building capacity for it and I hope it culminates at an opportune time. Our immediate goal is to put man in orbit (Lower Earth Orbit). The next one will be to prolong the mission and later to conduct space flights," he said.

 Space and human development

 SAC officials believe that the constantly-pushed boundaries of technological prowess can improve overall human resource development (HRD) for the country through research and development and operational capabilities. Kumar says that the successful missions not only encourage scientists to surge ahead but also inspire millions of young minds. "From my experience, I can say that nothing is difficult if we take a motivated group and provide a specific goal," Kumar says.

Mars launch setback as Isro finds snag onboard tracking ship
DC | 15 hours 39 min ago


 Bengaluru: India's Mars Orbiter could be launched a week behind the original schedule of Monday, October 28, as space scientists are reportedly grappling with a snag in equipment onboard one of the ships deployed in Pacific Ocean to track the probe immediately after its separation from the Polar Satellite Launch Vehicle (PSLV).
The launch authorisation board (LAB), which met inconclusively on Friday and Saturday, would meet again on Tuesday, October 22, to decide the date of launch after reviewing the readiness of communication terminals onboard two ships – Nalanda and Yamuna of the Shipping Corporation of India (SCI).
One of these ships – Nalanda – would drop anchor at Suva Port of Fiji on Saturday for refueling. ISRO's engineers would board the ship at Suva Port and test the telemetry, tracking and command (TTC) equipment before both ships sail to designated locations – near the Fiji islands in South Pacific Ocean, about 9000 nautical miles from India, to monitor the flight of the Orbiter, according to space scientists.
Officially, the delay in launch was attributed to bad weather which prevented these ships from reaching the designated location on time.
