Indian Startup Plans to Land on the Moon in January 2018 – India Real Time – WSJ

An Indian aerospace startup has said that it will launch its mission to the moon in a year’s time, as it takes part in a Google-funded competition to become the world’s first-ever privately held company to make a soft landing there.

Team Indus‘s rover, nicknamed ‘Ek Choti Si Asha,’ or ‘one small hope’ in Hindi, won the Axiom Research team a million-dollar prize from Google last year.

A group of more than 100 scientists and engineers, including around a dozen former ISRO scientists, make up Axiom Research Labs’ Team Indus. The team is India’s only entry in the Google-funded Lunar XPrize challenge, which has a bounty of $30 million.

To win the prize, a team has to successfully place a spacecraft on the moon’s surface, travel at least 500 meters and transmit high-definition video and images back to Earth.

“A full launch vehicle from ISRO [Indian Space Research Organization] will launch our spacecraft into the orbit of the moon end of 2017,” Rahul Narayan, the fleet commander of the team, said at a news conference in New Delhi on Thursday.

The Team Indus spacecraft is expected to make it to the moon’s Mare Imbrium region by January 2018.

The race is on. Sixteen other teams from across the world want to make the 238,900-mile trip, and Team Indus is the fourth team to announce its launch plans, said Mr. Narayan.

“We are considering the team from Israel great competition at this point,” he said.

The Indian team’s plan is the country’s first shot at becoming the fourth nation to land gently on the lunar surface and unfurl its national flag, after the U.S., Russia and China.

The South Asian nation’s inexpensive Mars mission put its satellite Mangalyan, which now appears on India’s new 2,000-rupee bank notes, into the red planet’s orbit for $74 million in September 2014. The U.S. spent $671 million getting its Maven satellite to Mars orbit.

The team said its mission would cost $60 million.

“We’ve already raised about $15 million through private equity,” said Julius Amrit, co-founder and director. The company aims to raise $20 million by charging companies or universities to put their instruments on board to collect data. It also expects to raise another $20 million from sponsorship, donations and grants.

Its top investors include Ratan Tata, chairman of the Tata group, one of India’s biggest conglomerates; Nandan Nilekani, co-founder of Indian outsourcing firm Infosys; and the owners of e-commerce website Flipkart Internet Pvt. Ltd.

“We are quite confident at this moment that we will have enough money to send our spacecraft to the moon,” Mr. Amrit said.

The Bangalore-based startup won a million dollar prize from Google last year for its WALL-E lookalike moon rover, which will shoot high-quality images, video and data and beam them from the moon’s surface to the company’s mission center in India.

 

But the mission isn’t without its challenges.“If you have to softly land, you need to be able to [precisely] manage your velocity and time [to switch your engines on and off],” said Dhruv Batra, Program Lead at Team Indus. “Unfortunately, there is no throttle-like mechanism in a spacecraft, like you have in a car.”

Another challenge is to be able to land at the right time of the day—to make sure the solar panels are able to power the gadgetry, while making sure the temperature isn’t too extreme for the batteries and other electronics to work properly.

“We are currently refining each and every output of our simulations to arrive at that level of precision we need,” said Mr. Batra.Seven years ago, Team Indus was one of the last teams to sign up for the Google challenge, and its founders had no prior experience in aerospace engineering or space sciences, said Mr. Narayan, the fleet commander. “It was just a dream.”

How India Helped Prove Einstein Right on Ripples and Gravity – India Real Time – WSJ

The discovery of gravitational waves announced Thursday has given momentum to Indian scientists hoping to be the first outside of the U.S. to host the device that detected the signals from the collision of two black holes.

Indian scientists contributed significantly to the decades long hunt for evidence of gravitational waves and in identifying that they were produced by the cosmic clash of black holes a billion light- years ago.

The discovery verifies an unproven portion of Albert Einstein’s Theory of General Relativity and, because the waves are largely unimpeded by matter, offers a new way for astronomers to probe formerly hidden corners of the universe. Einstein first suggestedthe existence of gravitational waves in 1916.

Around 30 Indians were part of a 1,000-strong team of researchers from 15 countries led by scientists at the California Institute of Technology and the Massachusetts Institute of Technology, that made the discovery using detectors at the Laser Interferometer Gravitational-Wave Observatory, or LIGO.

“I am so grateful for the major contributions, by Indian scientists working in India and abroad, that helped make this discovery and future discoveries possible,” said Kip Thorne, a Caltech theoretical physicist and co-founder of the LIGO project,  in a statement.

Indian data analysts developed and implemented techniques to find gravitational-wave signals amid noise and the country’s theorists computed the shapes of the signals, he added.

On Thursday, a tweet from the verified account of Indian Prime Minister Narendra Modi said he was “immensely proud that Indian scientists played an important role in this challenging quest.”

India Says Pollution Levels Need to Rise Further to Boost Growth – Businessweek

India said its pollution levels will need to increase in the years ahead to support its economic development and it won’t discuss limiting greenhouse-gas emissions at United Nations climate talks that began this week.

Environment Minister Prakash Javadekar also said the government is preparing to make a pledge on how India will develop cleaner forms of energy, though he stopped short of indicating when the country might take on the sorts of caps for emissions that the U.S., China and Europe are adopting.

“We have a need to grow, so our emissions will grow,” Javadekar said at a press conference in New Delhi today. He said the onus on reducing emissions should be on richer industrial nations most responsible for global warming to allow poorer countries “space for more development.”

The comments indicate the difficulty in bringing all of the 190 nations gathered at the UN climate talks in Peru this week into a deal that will cut back on the pollution blamed for driving up the Earth’s temperature. While India’s emissions are the third-highest in the world, 30 percent of its residents live in poverty, scraping by on 75 cents a day or less.

Javadekar spoke before departing for the UN talks in Lima, Peru, which run through next week. They’re aiming to put together the building blocks for a deal by the end of next year that would cut pollution in all nations from 2020.

India is under pressure to make its environmental goals more clear after China and the U.S. jointly agreed Nov. 12 to rein in fossil fuel emissions. It was the first time a big developing country said it would take on a mandatory limit on pollution.

China’s lunar rover: Well played, sir! | The Economist

SOMETHING has gone sadly wrong with Yutu, the lunar rover that China successfully launched and placed on the surface of the moon in December. But something has also gone very right with the way authorities have chosen to talk to the public about the setback. Officials have found a playful and, for China, very unusual way to break the bad news that the rover has malfunctioned, and that its operating life is probably coming to a premature end.

In addition to a straight news report about the malfunction, the state-run Xinhua news agency reported (in Chinese) on a “diary” in which the rover (pictured) delivered a feigned first-person account of its situation.

“Hello everyone,” it began. “Today is the 42nd day since I reached the moon. There are several bits of good news and one bit of bad news. Which do you want to hear first?”

The good news was that Yutu (or Jade Rabbit, a figure in Chinese lunar mythology) had travelled more than 100 metres on the lunar surface, and that its radar, cameras, particle analyser and infrared spectrometer had all collected valuable data.

But then came the bad news. “My masters found I have a mechanical control abnormality,\” the account said. “Some of my body parts will not obey their commands…I know there is a possibility I will not make it through this night.”

The unit’s failure would cut short the planned working life of the rover. Or, as Yutu explained in its diary, “I originally thought I could hop around here for three months, and tell everyone about all the kinds of big rocks I’d discover.”

Finally, Yutu signed off: “Goodnight, Earth. Good night, humanity.”

This innovative communications approach has earned admiring and warmhearted coverage in Western news media. It has also inspired a vast outpouring of supportive and sympathetic messages on Chinese social media, where the response to official news is often cynical and contemptuous.

India’s Mars mission enters second stage; outpaces space rival China | Reuters

India\’s first mission to Mars left Earth\’s orbit early on Sunday, clearing a critical hurdle in its journey to the red planet and overtaking the efforts in space of rival Asian giant China.

India's Polar Satellite Launch Vehicle (PSLV-C25), carrying the Mars orbiter, lifts off from the Satish Dhawan Space Centre in Sriharikota, about 100 km (62 miles) north of the southern Indian city of Chennai November 5, 2013 file photo. REUTERS/Babu

The success of the spacecraft, scheduled to orbit Mars by next September, would carry India into a small club, which includes the United States, Europe and Russia, whose probes have orbited or landed on Mars.

India\’s venture, called Mangalyaan, faces more hurdles on its journey to Mars. Fewer than half of missions to the planet are successful.

\”While Mangalyaan takes 1.2 billion dreams to Mars, we wish you sweet dreams!\” India\’s space agency said in a tweet soon after the event, referring to the citizens of the world\’s second-most populous country.

China, a keen competitor in the space race, has considered the possibility of putting a man on the moon sometime after 2020 and aims to land its first probe on the moon on Monday.
