China is developing an advanced new spaceship capable of both flying in low-Earth orbit and landing on the moon, according to state media, in another bold step for a space program that equaled the U.S. in number of rocket launches last year.

NewsGram brings to you top news around the world today.

The newspaper Science and Technology Daily cited spaceship engineer Zhang Bainian as saying the new craft would be recoverable and have room for multiple astronauts. While no other details were given in the Tuesday report, Zhang raised as a comparison the Orion spacecraft being developed by NASA and the European Space Agency. The agency hopes Orion will carry astronauts into space by 2023.

China’s Shenzhou space capsule used on all six of its crewed missions is based on Russia’s Soyuz and is capable of carrying three astronauts in its re-entry module.

China came late to crewed space flight, launching its first man into space in 2003, but has advanced rapidly since then. In its most recent crewed mission, two astronauts spent a month aboard a Chinese space station late last year.

A fully functioning, permanently crewed space station is on course to begin operations in around five years and a manned lunar mission has been suggested for the future.

Now firmly established among the big three in space travel, China last year moved ahead of Russia for the first time in number of rocket launches and equaled the United States at 22, according to Harvard University astrophysicist Jonathan McDowell. Russia had 17 launches, while the U.S. might have had several more if Space X’s Falcon 9 rocket fleet hadn’t been grounded following a Sept. 1 launchpad explosion. (VOA)

NASA’s human ‘computer’ is still working at age 80

Sue Finely calculated rocket trajectories by hand

Sue Finley still works at NASA

Sue Finley, now 80 years old and NASA’s longest-serving female employee, recalls her early days with the space agency when she worked as a human “computer,” calculating rocket trajectories by hand at a time when computers were huge and expensive to operate.

Finley arrived at Jet Propulsion Laboratory (JPL) in Pasadena, California, in January 1958, one week before the U.S. Army launched Explorer 1, America’s first earth satellite.

“It was a very big deal,” she recalls of the launch, a response to the launches a few months earlier of the first satellites, Sputnik 1 and 2, from the former Soviet Union.

She was at JPL for Pioneer 1, the first satellite sent aloft by the newly formed National Aeronautics and Space Administration (NASA) in late 1958, which marked the beginning of the international space race.

Unmanned space probes

Since then, Finley has had a role in nearly every U.S. unmanned space probe, and some missions of other nations.

There were failures to overcome and spectacular successes, but always new goals as scientists expanded our knowledge of the earth and solar system.

“We were certainly proud,” she says of NASA accomplishments, “but you just go to the next thing.”

Finley has been through several career changes with the space agency, one of the most important when NASA phased out human computers, moving, initially, to simple electronic versions.

“We got little tiny computers,” she recalls. “One I had 16 wires, jumper cables to code with. One had 10 pegboards that you programmed with.”

As modern computers took over navigational tasks, Finley developed and tested software as a subsystem engineer.

Among her career highlights: the Vega mission, a Soviet-French collaboration with Venus, and Halley’s Comet, which received navigational help from NASA and dropped balloons into the atmosphere of Venus.

She had to change the software for the antenna that tracked the mission, “and it worked,” Finley recalls. “Everything worked. That’s what was so exciting!”

Finley has worked since 1980 on NASA’s Deep Space Network, which coordinates satellite facilities in California, Spain and Australia that allow communication with space probes.

Highlights of NASA career

Career highlights include developing software that generates audio tones sent back from spacecraft, informing engineers on the ground what is happening in space. It was first developed for the Mars missions.

Each tone has a meaning that communicates data, noted one of Finley’s colleagues, Stephen Lichten.

“If a parachute opened, it would send a tone,” Lichten, manager for special projects for the Deep Space Network, said.

“The spacecraft lets go of its heat shield, and it would send a different tone, and so engineers like Sue were here listening for those special frequencies which told them the spacecraft was telling them what it has just done,” he said.

He notes that Finley also helped develop communication arrays that combine multiple antennas to act in unison and other advances that now crucial to space missions.

Lichten once shared an office with Finley and says she inspired her younger colleagues.

“There was a parade of people coming in constantly, to ask her advice, to ask her questions,” he recalls. “This was during the Venus balloon mission days and I realized that Sue was regarded as sort of a guru at JPL.”

Finley has been involved with nearly every advance in space communications in recent decades, and she continues her work today, Lichten said.

There are many more women at NASA today than there were when she started, and Finley said she tells young women to be inquisitive.

“I tell them to never be afraid to ask questions, never be afraid to say you don’t know,” she said.

After nearly six decades at the space agency, a mother of two grown sons and a mentor to her colleagues, Finley has no plans of retiring.

“There’s nothing else I want to do,” she said. “And so far, they need me.”

As they have since the earliest days of the space agency. (VOA)

Dalai Lama says that India and China have great potential

The spiritual leader feels that both the countries are doing compassionate works

New Delhi, Nov 19

Tibetan spiritual leader the Dalai Lama on Sunday said India and China have “great potential” and they could work together at a “practical level”.

“I think, a great potential… India and China combined are doing more compassionate work… At a practical level also. Imagine two billion people working together,” he told reporters here after inaugurating Smile Foundation’s initiative, The World of Children.

The spiritual leader, who has lived in India in self-imposed exile since 1959, said neither country had the “ability to destroy the other”.

“Whether you like it or not, you have to live side by side,” he said.

Underlining the ancient spiritual connection between the two countries, he said Chinese Buddhist Hsuan Tsang visited Nalanda (now in Bihar) and brought Nalanda Buddhist traditions to China.

“All thinkers of Nalanda are Indian. So Nalanda’s tradition is India’s tradition,” he said.

The Nalanda traditions had turned Tibetans, who were warriors, into more compassionate, peaceful and non-violent nation, he said.

“So sometimes in Delhi, teasing my Indian friend, (I say) if Tibet still remained in the previous way of life, like Mongols, Chinese invasion may not have taken place,” the Dalai Lama said in a lighter vein.

He said nobody in the world wanted violence but it was happening “because our minds are dominated by destructive emotions due to short-sightedness”.

“Nobody wants problems. Yet, many problems are our own creation.”

The Dalai Lama said the existing modern education was oriented to material values. India can take lead in improving the education system by combining modern education with ancient knowledge, he said. (IANS)

20 Years of Changing Seasons on Earth Captured into 2½ Minutes by NASA

NASA captured 20 years of changing seasons on Earth in a striking new global map of the home planet.

The data visualization, released this week, shows Earth’s fluctuations as seen from space.

The polar ice caps and snow cover are shown ebbing and flowing with the seasons. The varying ocean shades of blue, green, red and purple depict the abundance — or lack — of undersea life.

“It’s like watching the Earth breathe. It’s really remarkable,” said NASA oceanographer Jeremy Werdell, who took part in the project.

Two decades — from September 1997 to this past September — are crunched into 2½ minutes of viewing.

Werdell finds the imagery mesmerizing. “It’s like all of my senses are being transported into space, and then you can compress time and rewind it, and just continually watch this kind of visualization,” he said Friday.

Werdell said the visualization shows spring coming earlier and autumn lasting longer in the Northern Hemisphere. Also noticeable to him is the receding of the Arctic ice caps over time — and, though less obvious, the Antarctic, too.

On the sea side, Werdell was struck by “this hugely productive bloom of biology” that exploded in the Pacific along the equator from 1997 to 1998 — when a water-warming El Nino merged into cooling La Nina. This algae bloom is evident by a line of bright green.

In considerably smaller Lake Erie, more and more contaminating algae blooms are apparent — appearing red and yellow.

All this data can provide resources for policymakers as well as commercial fishermen and many others, according to Werdell.

Programmer Alex Kekesi of NASA’s Goddard Space Flight Center in Maryland said it took three months to complete the visualization, using satellite imagery.

Just like our Earth, the visualization will continually change, officials said, as computer systems improve, new remote-sensing satellites are launched and more observations are made. (VOA)
