The Indian Space Research Organisation (Isro) has lined up 18missions over the next 15 months. The upcoming launches include Chandrayaan-2, GAGAN (which will improve accuracy of GPS), Astrosat and others. Isro is also planning to launch a spacecraft to study microwave remote sensing along with NASA’s Jet Propulsion Laboratory (JPL).
K Radhakrishnan, chairman, Isro said, “No mission in the previous years or the missions in the future were affected because of the accelerated way of working (on MOM). In fact, we have had the accelerated way of working everywhere”.
He was responding to a question, on whether Isro has diluted its new launches, because of Mars Oribiter Mission (MOM), which was launched on November 5, after 15 months of preparation.
Isro has 18 missions lined up to March 2015, in 15 months, and there is a clear future direction till 2020. (Refer table below for the launches)
“There’s been a quantum jump in other programmes in the last 3-4 years,” said Radhakrishnan. Isro has had 82 launches in 35 years, but in the last four years alone there were 27 launches.
“We have not compromised. Each programme will have its own problems like technology or project issue,” he said.
Tie-up with NASA
Isro along with NASA’s Jet Propulsion Laboratory (JPL) is planning to launch a spacecraft to study microwave remote sensing.
Radhakrishnan said the project is about the study of pulse to know what is not normally visible in cloudy conditions. In remote sensing, depending on the frequency one can identify what’s there by depending on the frequency characteristic change. For instance, the ‘L’ band studies vegetation. Another one, the S band gives another study. Or, the X band gives another feel, he said.
“We have done studies with the C Band. In the project with JPL, we will look at both L and S band,” he said.
“The spacecraft will be made by us. There’s a very large antenna required which will be a 12 metre diameter antenna. This will be launched by 2019-20. In the second phase, we do the project report preparation. Then, we work on the satellite together, ” he said.
He said that in case of Chandrayaan, NASA brought the instruments. In this case, it will be a collaboration and both the agencies will work together. There could be also be collaborations in the areas of lunar exploration, and for exploring the sun and Mars explorations.
“We can have a larger mission. We are able to do that. The next one has to be a more complex mission. We did a joint project of building a satellite with the French called Megha Tropiques a while ago. We had worked with the French on developing two landers. We have now done a joint study with NASA’s Jet Propulsion Laboratory (JPL),” said Radhakrishnan.

Yep, the craft hit 78,000 Kms instead of 100,000 as planned. Supplementary burn will be done on 12th.

Everything is under control, says ISRO
The fourth firing of the propulsion system of the Mars spacecraft on Monday morning was among the six exercises planned by the ISRO and aimed at achieving an apogee of 1.92 lakh by the fifth move, scheduled for November 16.
The craft must leave the Earth orbit on November 30/December 1 if it has to meet Mars as planned for mid-September next year.
The release said the spacecraft was in good health and its apogee had been moved to 78,276 km now.
The other point or perigee remains at nearly 250 km from Earth.
In the latest engine burn, the ISTRAC team managed to impart an incremental velocity of 35 metres/second as against the required 130 m/second.
The ISRO described the performance shortfall as part of ongoing trials that its scientists performed to ensure all systems would be in order later during the orbiter’s long journey to Mars.
‘No reason to panic’
An official involved in the building of the Mars spacecraft said, “Everything is safe and under control. There is no reason for panic.”
ISRO scientists explained to The Hindu that the 440-Newton engine onboard is equipped with a primary and a redundant electrical coil that enable the fuel and the oxidiser to flow through two valves of the spacecraft.
During the firing on Monday morning, the team was trying to use both the primary and the redundant coils together as part of a trial. However, there was no fuel flow in this mode and the orbiter could not pick up the required velocity or reach the desired higher orbit.
Meanwhile, the time slot for firing the engine had expired as the spacecraft had moved away.
A senior engineer involved in the process said, “Both the coils are working independently (but not if they are switched on together.) Tomorrow we will use the primary coil (as they did on November 7, 8 and 9.) It’s a very minor issue. We are confident that we will overcome it.”
He explained: “In the last three firings we operated only the primary coil. Today we wanted to conduct a trial. We first operated the primary coil and the redundant coil later, and both worked independently. We then switched on both together in the test firing today but the system did not work in that mode. So we went back to using them separately and they worked well.”
The release said, “In the fourth orbit-raising operation conducted on November 11, the apogee (the farthest point to Earth) of the Mars Orbiter spacecraft was raised from 71,623 km to 78,276 km by imparting an incremental velocity of 35 metres/second (as against 130 m/second originally planned to raise the apogee to about 1,00,000 km). The spacecraft is in normal health. A supplementary orbit-raising operation is planned tomorrow (November 12) at 0500 hrs.”

Happy to help .....
Are there any plans to train astronauts in India or abroad by 2020? Any such dedicated program / facility in progress inside India to date regarding this?
India seems to have a lot of potential in space exploration but I've not heard much about India planning to send its first astronauts into space.
