Named for Roman war god, Mars is not very polite for visitors



CAPE CANAVERAL, Fla. (AP) – When Mars comes to accept visitors, Mars has a bad habit to live up to the mythological name and burn the Earth thoroughly.

NASA's InSight is the latest spacecraft that comes with the intention of deeper landing and digging into the planet than anything you want to come. After a six-month trip, Lander arrived in Mars on Monday.

Rob Grover, the chief engineer of the landing gear at NASA's Jet Propulsion Laboratory, said: at We have now successfully accomplished several successive landings. But you never know what Mars will do to you. Ancak

The landing at Mars is always risky, with Grover and other experts throwing stress at every turn.

”Our job on the landing gear is to be paranoid about what might go wrong and make sure we're doing everything we can to make sure things go right,“ he said.

The numbers support him. Only 40 percent of all missions to Mars, the Roman god of war, were successful.

"It's really hard to go to Mars," said Thomas Zurbuchen, NASA's top science mission chief. "As humanity, explorers all over the world spend about 50 percent or less."

The US is the only country that successfully operates a spacecraft on the surface of Mars. InSight represents the ninth attempt of NASA to deploy a spacecraft to Mars; just one effort failed.

The latter – NASA's Enthusiast mobile – is more than 12 miles (20 km) in the odometer, still on the move, six years later. The space agency's old, small Opportunity was moving there until June, when a global duststorm was out of service. Flight controllers haven't lost their hopes, but they're going to be alive again.

Human history's attempt to reach Mars for about 60 years involves attempts to take photographs of the red planet incessantly and at the same time to place the spacecraft in orbit around the red planet, and to attempt much more complex efforts to actually land in the land.

NASA's Mariner 4 made the first successful flight of the red planet in 1965 and sent 21 pictures back.

Mariner 9 entered orbit around Mars and beamed back over 7,000 photos.

And NASA's Vikings 1 and 2, 1977, not only placed them in orbit around Mars, but also on the surface. The Twin Vikings were the first successful descendants of Mars from planet Earth.

The 1990s were not polite to NASA. A degrading British metric transformation curve was in 1993 when Mars was the judge of the Observer. Then another US orchestra, a land that also had to penetrate the surface, and two accompanying probes were also lost.

Despite years of experimentation, Russia was unlucky, especially in Mars.

At that time, the Soviet Union made its first flight of Mars in 1960. The spaceship never reached Earth orbit. After further launch failures and flight failures, the Soviets finally bought a pair of spacecraft in Mars in orbit in 1971 and recovered the actual data. However, it was the total bust of the comrades.

And he went to the Soviets / Russians in 2011 with his latest initiatives with China. The goal for victory was to construct a spacecraft to Phobos and to place a second spacecraft into orbit around Mars to gather and bring back samples. It didn't leave Earth orbit.

As in Japan, Mars also bitten the snake in Europe.

While the European Space Agency had satellites operating around Mars, both landing attempts fell. Just two years ago, the soil hit the surface very quickly, he dug a crater. Japan's only Mars spacecraft launched in 1998 did not enter orbit.

Meanwhile, India has been operating a satellite around Mars for four years, first and only on a red planet.

NASA has a heavy European presence in InSight. While Germany assumes the mechanical mole designed to place 16 meters (5 meters) on the surface of Mars to take underground heat measurements, France manages the ship's seismic seismometry.

On the surface, the only thing that works on Mars is curiosity. Currently in orbit: US Odyssey since 2001, Europe Mars Express (2003), US Mars Discovery Slot (2006), US Maven (2014), India's Mangalyan Orbiter (2014) and Europe & # 39; s Trace Gas Orbiter (2016).
