NASA will launch another Mars mission

NASA to launch another Mars mission in 2016


Mars Mission


Encouraged by the success of “Curiosity”, NASA has announced to launch a new Mars mission in 2016 to take a better look into the guts of the Red Planet.


The mission called “InSight” will investigate why Mars’ crust is not divided into tectonic plates that drift like Earth’s.

Detailed knowledge of the interior of Mars in comparison to Earth will help scientists understand better how terrestrial planets form and evolve, the American space agency said.


“The exploration of Mars is a top priority for NASA, and the selection of ‘InSight’ ensures we will continue to unlock the mysteries of the Red Planet and lay the groundwork for a future human mission there,” said NASA administrator Charles Bolden.


“The recent successful landing of the Curiosity rover has galvanised public interest in space exploration and today’s announcement makes clear there are more exciting Mars missions to come,” he said referring to the success of Curiosity.


The 12th selection in NASA’s series of Discovery-class missions, ‘InSight’ is build on spacecraft technology used in the space agency’s highly successful Phoenix lander mission, which was launched to the Red Planet in 2007 and determined water existed near the surface in the Martian polar regions.

“Our Discovery Programme enables scientists to use innovative approaches to answering fundamental questions about our solar system in the lowest cost mission category,” said John Grunsfeld, associate administrator for the Science Mission Directorate at NASA Headquarters.


“’InSight’ will get to the ‘core’ of the nature of the interior and structure of Mars, well below the observations we’ve been able to make from orbit or the surface,” Grunsfeld said.

NASA Curiosity Travel Plans

NASA shares Mars rover Curiosity's travel plans

Curiosity Rover

NASA on Friday unveiled plans for its Mars rover Curiosity's first road trip, part of a two-year quest to determine if the planet most like Earth could ever have hosted microbial life, scientists said.

The one-ton nuclear-powered robotic science lab landed in a large crater near Mars' equator on August 6 to search for organic materials and other chemistry considered key to life.

The rover's primary target is Mount Sharp, a mound of layered rock three miles (5 km) high rising from the floor of Gale Crater.

Before beginning the 4.3-mile (7-km) trek to the base of Mount Sharp, a journey expected to take months, the six-wheeled Curiosity will visit a relatively nearby site named "Glenelg," which caught scientists' interest because it includes three types of terrain.

The name was selected from a list of about 100 rock formations in northern Canada. Scientists realized Glenelg was a palindrome -- a word that reads the same backward -- and particularly suited as the name for Curiosity's first destination since the rover will have to come back through the site to head to Mount Sharp.

The road trip to Glenelg depends in part on how well Curiosity cruises through the rest of its instrument checkout. Early next week, the rover will test-fire its powerful laser to pulverize a bit of bedrock uncovered by exhaust from Curiosity's descent engine.

A small telescope will then analyze the vaporized material to determine what minerals it contains.

The combined system, known as Chemistry & Camera, or ChemCam, is designed to make about 14,000 measurements throughout Curiosity's mission, said lead instrument scientist Roger Wiens, with the Los Alamos National Laboratory.

"There's a high-power laser that briefly projects several megawatts onto a pinhead-size spot on the surface of Mars," Wiens said. "It creates a plasma, or a little ball of flame or spark."

The telescope, which can observe the flash from up to about 25 feet (7 meters) away, then splits the light into its component wavelengths.

Scientists use that information to determine chemical composition.

Travel to Glenelg, located about 1,600 feet (500 meters) away from Curiosity's landing site, should take a month or longer, depending on how many stops scientists decide to make along the way.

"Probably we'll do a month worth of science there, maybe a little bit more," lead mission scientist John Grotzinger told reporters during a conference call on Friday. "Sometime toward the end of the calendar year, roughly, I would guess then we would turn our sights toward the trek to Mount Sharp."


NASA rover prepares to use laser on a Martian rock


Curiosity Laser work

The NASA Mars rover Curiosity is preparing for its first laser target practice — zapping a Martian rock 10 feet (3 meters)away on Saturday night. Since landing in an ancient crater Aug. 5, the car-size Curiosity has been getting a full health checkup. 
Scientists said Friday they have chosen a generic-looking rock near the landing site to aim the laser at and burn a small hole. The laser is one of 10 tools Curiosity will use to study whether the environment was favorable for microbial life.
 Engineers next week planned to command Curiosity to turn its wheels side-to-side and then take its first short drive that will involve rolling forward 10 feet, turning 90 degrees and then going in reverse. 
After the checkups are done, the rover will head 1,300 feet (396 meters) east to a spot where three different types of terrain converge in a drive that will take about a month. By year's end, it will start its trek toward a mountain rising from the crater floor. 



Kalpana Chawla Biography

Kalpana Chawla - The Inspiration to Everybody


Kalpana Chawla (July 1, 1961 – February 1, 2003) was an Indian-American astronaut who, was a mission specialist on the space shuttle Columbia. She first flew on the Columbia in 1997 as a mission specialist and primary robotic arm operator. Chawla was one of seven crew members killed in the Space Shuttle Columbia disaster.

Kalpana Chawla


Education :

Chawla completed her earlier schooling at Tagore Public SchoolKarnal and her Bachelor of Engineering degree in Aeronautical Engineering at Punjab Engineering College at Chandigarh in 1982. She moved to the United States in 1982 and obtained a M.S. degree in aerospace engineering from the University of Texas at Arlington in 1984. Chawla went on to earn a second M.S. degree in 1986 and a Ph.D. in aerospace engineering in 1988 from the University of Colorado at Boulder. Later that year she began working at the NASA Ames Research Center as vice president of Overset Methods, Inc. where she did CFD research on Vertical/Short Takeoff and Landing concepts. Chawla held a Certificated Flight Instructor rating for airplanes, gliders and Commercial Pilot licenses for single and multi-engine airplanes, seaplanes and gliders.

NASA Carrier :

Chawla joined the NASA 'Astronaut Corps' in March 1995 and was selected for her first flight in 1996. She spoke the following words while traveling in the weightlessness of space, "You are just your intelligence". She had traveled 10.4 million km, as many as 252 times around the Earth.
Her first space mission began on November 19, 1997 as part of the six-astronaut crew that flew the Space Shuttle Columbia flight STS-87. Chawla was the first Indian-born woman and the second Indian person to fly in space, following cosmonaut Rakesh Sharma who flew in 1984 in a spacecraft. On her first mission Chawla traveled over 10.4 million miles in 252 orbits of the earth, logging more than 372 hours in space. During STS-87, she was responsible for deploying the Spartan Satellite which malfunctioned, necessitating a spacewalk by Winston Scott and Takao Doi to capture the satellite. A five-month NASA investigation fully exonerated Chawla by identifying errors in software interfaces and the defined procedures of flight crew and ground control.
After the completion of STS-87 post-flight activities, Chawla was assigned to technical positions in the astronaut office to work on the space station, her performance in which was recognized with a special award from her peers.

In 2000 she was selected for her second flight as part of the crew of STS-107. This mission was repeatedly delayed due to scheduling conflicts and technical problems such as the July 2002 discovery of cracks in the shuttle engine flow liners. On January 16, 2003, Chawla finally returned to space aboard Columbia on the ill-fated STS-107 mission. Chawla's responsibilities included the microgravity experiments, for which the crew conducted nearly 80 experiments studying earth and space science, advanced technology development, and astronaut health and safety.


Death : 
Chawla died in the Space Shuttle Columbia disaster which occurred on February 1, 2003, when the Space Shuttle disintegrated over Texas during re-entry into the Earth's atmosphere, with the loss of all seven crew members, shortly before it was scheduled to conclude its 28th mission, STS-107.

Awards : 
Posthumously awarded:
  • Congressional Space Medal of Honor
  • NASA Space Flight Medal
  • NASA Distinguished Service Medal

Neil Armstrong Short Story

Neil Armstrong, first man on Moon, dies at 82


Neil Armstrong


Neil Armstrong, the legendary US astronaut, who in 1969 took "one giant leap for mankind" by becoming the first man to set foot on the moon, has died at the age of 82, his family said on Saturday.

Armstrong died just weeks after he underwent a heart surgery, and his family said in a statement that he passed away following complications resulting from cardiovascular procedures, according to US media reports.

July 20, 1969 became a watershed date in the history of mankind after Armstrong, commanding the Apollo 11 spacecraft landed on the moon, and accompanied by fellow astronaut Edwin Aldrin spent nearly three hours walking on the moon.

"That's one small step for a man, one giant leap for mankind," is how Armstrong had broken the historic news from the Earth's satellite when he radioed back.
It had taken Apollo 11 craft, carrying Armstrong and fellow astronauts Buzz Aldrin and Michael Collins, four days to complete the nearly 250,000-mile (400,000 kms) journey, as the world waited with bated breath.

"While we mourn the loss of a very good man, we also celebrate his remarkable life and hope that it serves as an example to young people around the world to work hard to make their dreams come true, to be willing to explore and push the limits, and to selflessly serve a cause greater than themselves," his family said in a statement.

"For those who may ask what they can do to honour Neil, we have a simple request. Honour his example of service, accomplishment and modesty, and the next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink," they said.

Paying tribute to the legendary astronaut, US President Barack Obama said, "Neil was among the greatest of American heroes, not just of his time, but of all time. When he and his fellow crew members lifted off aboard Apollo 11 in 1969, they carried with them the aspirations of an entire nation."

"They set out to show the world that the American spirit can see beyond what seems unimaginable, that with enough drive and ingenuity, anything is possible," Obama said.

Obama said that he and the first lady are deeply saddened by his death. For those who may ask what they can do to honour Neil, the family said they have a simple request: "Honour his example of service, accomplishment and modesty, and the next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink."

Armstrong inspired generations of Americans to believe that America is capable of achieving greatness that only comes with determination, perseverance, and hard work, US Defence Secretary Leon Panetta said.

"As a true pioneer, his one small step showed all mankind the great feats we can accomplish when we set ourselves to the task. While Neil is no longer with us, his spirit and his legacy of American achievement and national pride will live forever," Panetta said paying tribute to the legendary US astronaut. Mitt Romney, the Republican presidential candidate, said Neil Armstrong today takes his place in the hall of heroes.

"With courage unmeasured and unbounded love for his country, he walked where man had never walked before. The moon will miss its first son of earth," he said.

"I met and spoke with Neil Armstrong just a few weeks ago--his passion for space, science and discovery, and his devotion to America will inspire me through my lifetime," Romney said.

NASA Administrator Charles Bolden said as long as there are history books, Armstrong will be included in them, remembered for taking "humankind's first small step on a world beyond our own". Besides being one of America's greatest explorers, he carried himself with a grace and humility that was an example to all, Bolden said.

Democratic leader Nancy Pelosi said Armstrong was an American hero who never looked back, always moving the nation into new generations of exploration.

"When Neil Armstrong took his small step, Americans knew we could overcome any obstacle and prevail over any challenge. Throughout the rest of his life, he continued to work to inspire the next generation, to careers in science and innovation, to lives of service, to broad and bold perspectives," she said.

"Neil Armstrong was a true American hero, both because of his extraordinary service to his country and the honourable life he led. He was a groundbreaking Naval aviator and the world's most famous astronaut, but it was his humble and gracious response to the torrent of attention that followed his accomplishments that may have set him apart most," Ohio Senator Rob Portman said. His family in the statement described him as "a reluctant American hero who always believed he was just doing his job”.

"Neil Armstrong was a true American hero, both because of his extraordinary service to his country and the honourable life he led. He was a ground breaking Naval aviator and the world's most famous astronaut, but it was his humble and gracious response to the torrent of attention that followed his accomplishments that may have set him apart most," Ohio Senator Rob Portman said.

In one of his rare public appearances at a gathering with Aldrin and other Apollo astronauts to mark the 30th anniversary of their moon landing, he recognised the importance of his achievement.

"In my own view, the important achievement of Apollo was a demonstration that humanity is not forever chained to this planet, and our visions go rather further than that, and our opportunities are unlimited," Armstrong said.

NASA's Curiosity on Mars


Mars rover Curiosity transmits low-resolution landing video



The Curiosity rover is a car-sized Mars rover currently exploring Gale Crater, near the equator of Mars. The rover is the largest to date, and is designed to examine whether Mars could have once supported life. It arrived on the Martian surface on 6 August 2012, after leaving Earth on 26 November 2011.


Coriosity


The rover is a nuclear-powered, mobile scientific laboratory, with dozens of instruments. It is part of NASA's Mars Science Laboratory(MSL) mission bythe United States. The MSL mission has four scientific goals: investigation of the Martian climate, geology, and whether Mars could ever have supported life, including investigation of the role of water. It is also useful preparation for future missions, perhaps amanned mission to Mars. Curiosity carries the most advanced payload of scientific equipment ever used on the surface of Mars.

The MSL spacecraft carrying Curiosity was launched on November 26, 2011, and the rover was successfully landed on Aeolis Palus inGale Crater on August 6, 2012 UTC (August 5, 2012 PDT, NASA mission control time)


NASA Curiosity Landing Video :





Previous NASA Mars rovers only became active after the successful entry, descent and landing on the Martian surface. Curiosity, on the other hand, utilized the rover suspension system for the final set-down of the active rover on the surface of Mars.

Curiosity transformed from its stowed flight configuration to a landing configuration while the MSL spacecraft simultaneously lowered it beneath the spacecraft descent stage with a 20 m (66 ft) tether from the "sky crane" system to a soft landing—wheels down—on the surface of Mars. After the rover touched down it waited 2 seconds to confirm that it was on solid ground and fired several pyros (small explosive devices) activating cable cutters on the bridle to free itself from the spacecraft descent stage. The descent stage then flew away to a crash landing, and the rover prepared itself to begin the science portion of the mission.
