Japanese government today revealed the names of 85 foreign recipients of Spring Imperial Decorations. The honors include four Indians, including leading scientist, C.N.R. Rao, and former principal secretary to Prime Minister T.K.A. Nair.
The Order of the Rising Sun is awarded for to those who have made remarkable contributions in the fields of international relations, promotion of Japanese culture, development in welfare or preservation of the environment.
A Japanese embassy release said that the presentation ceremony will be held at the Imperial Palace in Tokyo on May 8, when the foreign recipients will be given an audience with the Emperor of Japan.
Rao, who is also a Bharat Ratna recipient, would be awarded with the Order of the Rising Sun, Gold and Silver Star for his “contribution to promoting academic interchange and mutual understanding in science and technology between Japan and India”.
Nair would be honored with the Order of the Rising Sun, Gold and Silver Star for his “contribution to the enhancement of relations and the promotion of friendship between Japan and India.”
President of Indo-Japanese Association, Mumbai, Nikunj Parekh, would be conferred the Order of the Rising Sun, Gold and Silver Rays, for his input in the promotion and presentation of Japanese Culture in India.
The top Japanese honor for a contribution in the activities of the Japanese overseas establishment will be given to Topgay Bhutia, a former Japanese embassy employee in India.
Two satellites developed in Europe and Japan are on their way to the Sun’s closest planet Mercury. It is likely to take them seven years to reach their destination.
The joint endeavour BepiColombo left Earth on an Ariane rocket that launched out of South America on Friday, the BBC said.
The probes lifted clear of the Kourou spaceport in Atlantic coast of French Guiana at 10.45 p.m. on Friday.
Mission controllers based in Darmstadt, Germany, would spend much of Saturday talking to the spacecraft, to confirm they were properly configured for the long cruise ahead.
Coming close on the heels of NASA’s Parker Solar Probe that was launched in August, Bepi is aimed at finding more about Mercury that “doesn’t really fit with our theories for how the Solar System formed”, said Bepi scientist Professor Dave Rothery from the UK’s Open University.
“We can’t understand our planet fully unless we’re able to explain Mercury that has an oversized iron core — 60 per cent of its mass,” Rothery said.
Science has not yet explained why the planet only has a thin veneer of rocks. Bepi’s high-resolution data should bring us nearer to an answer, the BBC reported.
It’s the first time the European and Japanese space agencies (Esa and Jaxa) have set out for Mercury. The Americans have already been there, briefly with the Mariner 10 probe in the 1970s, and with the Messenger orbiter earlier this decade.
Messenger discovered that water-ice is held inside some of Mercury’s shadowed craters, and that its crust contains a lot of graphite (pencil lead).
Bepi will build on those. The new mission carries twice as much instrumentation and will get closer for longer.
Mercury’s dense body does not reflect its initial form. It’s possible the planet began life much further and later migrated inwards, mission scientist Suzie Imber from Leicester University.
“It’s also got huge cliffs, many kilometres tall. And those cliffs formed as Mercury shrank. We call them wrinkle ridges,” Imber said.
It is possible to directly reach Mercury in a matter of months, but the speed picked up by a spacecraft falling into the Sun’s deep gravity would make it very hard to stop at the planet, the BBC report said.
Bepi will take a more circuitous route. It will fly past Earth, Venus and Mercury itself, using the tug of their gravity to bleed off speed, so that by 2025 the mission can gently slot into position.
The toughest prospect ahead is the heat. At just 58 million km from the Sun, working at Mercury is like being in a pizza oven, Imber said.
The sides of the probes in direct sunlight will have to cope with temperatures over 400 degrees Celsius. Even those surfaces facing away from the Sun have to be protected.
Coping strategies include covering the MMO in thick blankets of insulation material made from titanium and ceramics. “The environment is extremely hostile,” explains Esa mission controller Elsa Montagnon.
“On Mercury, we get 10 times the solar energy we get on Earth. But then from the illuminated side of Mercury, we get about four times what we get on the Earth. So, the spacecraft are continually in a heat sandwich,” Montagnon said.
The mission is an expensive one. It’s estimated the costs borne by the European Space Agency and the Japanese space agency amount to about 1.65 billion euros.
Additionally, national space agencies in Europe have paid for the instrumentation on the MMO, taking the overall budget above 3 billion euros.
