The mission's investigations at the Kimberley are planned as the most extensive since Curiosity spent the first half of 2013 in an area called Yellowknife Bay

At the Kimberley

researchers plan to use Curiosity's science instruments to learn more about habitable past conditions and environmental changes.

Four young men who have been paralyzed for years achieved

moving their legs—as a result of epidural electrical stimulation of the spinal cord

All four participants were classified as suffering from chronic, motor complete spinal cord injuries and were unable to move their lower extremities prior to the implantation of an epidural stimulator

First astronauts selected

In 1959, NASA announced the selection of America's first seven astronauts for project Mercury. Scott Carpenter, Gordon Cooper, John Glenn, Gus Grissom, Wally Schirra, Alan Shepard and Donald Slayton were chosen from 110 applicants. Their training program at Langley, which ranged from a graduate-level course in introductory space science to simulator training and scuba-diving. Project Mercury, NASA's first high profile program, was an effort to learn if humans could survive in space. NASA required astronaut candidates to be male, not over 40 years old, not more than 5' 11" height and in excellent physical condition. On 5 May 1961, Shepard became the first American in space

Apollo 13 launch

1970, Apollo 13, the third manned lunar landing mission, began with the successful launch of the spacecraft Odyssey from Cape Canaveral with crew James Lovell, Fred Haise, and John Swigert. Two days later, on 13 Apr disaster struck 200,000 miles from earth. A liquid oxygen tank exploded, disabling the normal supply of oxygen, electricity, light, and water. Swigert reported: “Houston, we've had a problem.” The lunar landing was aborted. After circling the moon, the crippled spacecraft began a long, cold journey back to earth with enormous logistical problems in providing enough energy to the damaged fuel cells to allow a safe return. On 17 Apr, with the world anxiously watching, tragedy turned to triumph as the Apollo 13 astronauts touched down safely in the Pacific Ocean

Apollo XIII rescue

In 1970, an explosion during the Apollo 13 mission led to one of the most spectacular rescue missions in US space history. The explosion aboard the Odyssey spacecraft left the crew stranded for four days more than 200,000 miles from Earth. An oxygen leak forced the Apollo 13 astronauts to abandon ship and return in lunar module. Against all odds, the three astronauts and thousands of others brought the capsule safely back to Earth. The astronauts were Fred Haise, Jack Swigert, and Commander Jim Lovell, and the mission was to have made the third manned landing of the moon

Helicopter

In 1877, a steam-engine driven helicopter model built by Enrico Forlanini rose 40 ft (12 m). The machine weighed 3.5 kg (7.7 lbs). Its coaxial rotors were powered by a two-cylinder steam engine. Just before takeoff the spherical steam accumlator was charged with 10 atmospheres of pressure, enabling the craft to rise and remain aloft for 20 seconds. Forlanini (1848-1930) was an Italian pioneer of scientific aviation. He built a hydroplane, which could take off on water (1905) and a new type of semirigid aircraft in1914. He also invented the hydrofoil boat. Alexander Graham Bell secured the Italian's patents to pursue his own interest in hydrofoil development

a lunar eclipse tetrad—a series of 4 consecutive total eclipses occurring at approximately six month intervals

The total eclipse of April 15, 2014, will be followed by another on Oct. 8, 2014, and another on April 4, 2015, and another on Sept. 28 2015.

 First woman to fly across English Channel

In 1912, American aviator Harriet Quimby became the first female pilot to fly across the English Channel. She left England in a 50-hp monoplane lent to her by Louis Blériot. She headed for France in a plane she had never flown before and a compass she had just learned how to use. Despite poor visibility and fog, Quimby landed 59 minutes later near Hardelot, France. Upon landing, she was greeted by the local residents, but the Titanic sinking just days earlier, limited reporting of Quimby's achievement in the world press. She died the same year, on 1 Jul 1912, when she lost control of her plane at a flying exhibition near Quincy, Mass. She was the first American woman to become a licensed pilot, but her career as a pilot lasted a mere 11 months.

 Indian satellite

In 1975, the first satellite built in India was launched from Volgograd Launch Station, Russia, on a Soviet Intercosmos C-1 rocket. It was named Aryabhata, after a noted 5th-century Indian mathematician. The 360-kg satellite had been built during 20 months by the Indian Space Research Organization (ISRO) in Peenya, Bangalore, by a team led by Prof. U. R. Rao. Its shape was a 26-sided polygon, 1.4-m diam., with all faces covered in solar cells, except the top and bottom. It was designed to carry out experiments in X-ray astronomy, aeronomics, and solar physics, communicating with a 46-watt VHF transmitter. However, after only 4 days in orbit, a power failure ended any further experiments. It remained in orbit nearly 17 years, until it reentered the Earth's atmosphere on 11 Feb 1992

Surgery book

In 1575, printing of Ambroise Paré's book Oeuvres Complètes (Complete Works) was finished, but its publication was opposed by establishment physicians. His previous texts on surgery had popularized a new way to treat gunshot wounds without cauterisation, reintroduced the ligature in amputation, and improved midwifery techniques. These many writings were gathered together in this one new volume, which spread his teachings throughout the world. It remained in print for a century and ran to thirteen editions. He wrote in French instead of Latin with practical, common sense so that many barber-surgeons, who (like Paré) were unable to interpret Latin, had access to medical knowledge otherwise unavailable from Latin texts
