ISRO gets ready for next GSLV flight with indigenous cryogenic engine

Flush with the success of the GSLV-D5, which used an indigenous cryogenic stage to put the GSAT-14 into orbit, the Indian Space Research Organisation is getting ready for the next GSLV flight with its own cryogenic engine within a year. It will put the communication satellite GSAT-6 into orbit.

Announcing this at a press conference at the spaceport at Sriharikota on Sunday, ISRO Chairman K. Radhakrishnan said there would be a series of GSLV flights with indigenous cryogenic engines and they would put into orbit GSAT-6, 7A and 9, GISAT, Chandrayaan-2 and a few more communication satellites of the two-tonne class. “We are proceeding with the development of the GSLV-Mark III which will put a 4,000-kg satellite into orbit. Within a few months, we will have an experimental mission of the GSLV-Mark III to understand the vehicle’s performance during the atmospheric phase,” he said.
Answering a question on the commercial potential of the GSLV with India’s own cryogenic engine, Dr. Radhakrishnan said that while the trend now was to build 5.5-tonne satellites, there was a niche market for two-tonne communication satellites. Satellites weighing 3.2 tonnes to 4.5 tonnes were being built in the world. “So there is a set of satellites” which could be put into orbit by the GSLV.
A number of satellites had been lined up to be put into orbit by the ISRO’s Polar Satellite Launch Vehicle, he said. The heaviest of them will be an 800-kg satellite from Germany. The PSLV would orbit three satellites from the U.K, each weighing about 200 kg.
Indeed, the ISRO will have a busy schedule, with five navigational satellites under the Indian Regional Navigational Satellites System (IRNSS) in the orbit by March 2015. They will all fly onboard the PSLV. The IRNSS-1VB will be put into orbit in March this year from Sriharikota. The IRNSS-1C, 1D and 1E would follow. A PSLV placed the IRNSS -1A into orbit in 2013.
India has been invited to take part in experiments onboard the International Space Station, Dr. Radhakrishnan said.
The ISRO and NASA would jointly build a satellite with synthetic aperture radar for earth observations. A.S. Kiran Kumar, Director, Space Applications Centre of the ISRO, Ahmedabad, was working with the Jet Propulsion Laboratory for preparing the project report related to the spacecraft, he said.

NGT terminates chairmen of pollution control boards in 10 states (downtoearth,)

Cracking the whip on 10 State Pollution Control Boards (SPCBs) for ad-hoc appointments, the National Green Tribunal has ordered the termination of Chairpersons of these regulatory authorities. The concerned states are Himachal Pradesh, Sikkim, Tamil Nadu, Uttarakhand, Kerala, Rajasthan, Telangana, Haryana, Maharashtra and Manipur. The order was given last week by the principal bench of the NGT, chaired by Justice Swatanter Kumar. The recent order of June 8, 2017, comes as a follow-up to an NGT judgment given in August 2016. In that judgment, the NGT had issued directions on appointments of Chairmen and Member Secretaries of the SPCBs, emphasising on crucial roles they have in pollution control and abatement. It then specified required qualifications as well as tenure of the authorities. States were required to act on the orders within three months and frame Rules for appointment [See Box: Highlights of the NGT judgment of 2016 on criteria for SPCB chairperson appointment].

High dose of Vitamin C and B3 can kill colon cancer cells: study (downtoearth)

In a first, a team of researchers has found that high doses of Vitamin C and niacin or Vitamin B3 can kill cancer stem cells. A study published in Cell Biology International showed the opposing effects of low and high dose of vitamin C and vitamin B3 on colon cancer stem cells. Led by Bipasha Bose and Sudheer Shenoy, the team found that while low doses (5-25 micromolar) of Vitamin C and B3 proliferate colon cancer stem cells, high doses (100 to 1,000 micromolar) killed cancer stem cells. Such high doses of vitamins can only be achieved through intravenous injections in colon cancer patients. The third leading cause of cancer deaths worldwide, colon cancer can be prevented by an intake of dietary fibre and lifestyle changes. While the next step of the researchers is to delineate the mechanisms involved in such opposing effects, they also hope to establish a therapeutic dose of Vitamin C and B3 for colon cancer stem cell therapy. “If the therapeutic dose gets validated under in vivo...

SC asks Centre to strike a balance on Rohingya issue (.hindu)

Supreme Court orally indicates that the government should not deport Rohingya “now” as the Centre prevails over it to not record any such views in its formal order, citing “international ramifications”. The Supreme Court on Friday came close to ordering the government not to deport the Rohingya. It finally settled on merely observing that a balance should be struck between humanitarian concern for the community and the country's national security and economic interests. The court was hearing a bunch of petitions, one filed by persons within the Rohingya community, against a proposed move to deport over 40,000 Rohingya refugees. A three-judge Bench, led by Chief Justice of India Dipak Misra, began by orally indicating that the government should not deport Rohingya “now”, but the government prevailed on the court to not pass any formal order, citing “international ramifications”. With this, the status quo continues even though the court gave the community liberty to approach i...
