European Space Agency led Mars lander starts descent to red planet

European Space Agency said Schiaparelli will enter the atmosphere Wednesday at a speed of nearly 21,000 kilometers per hour, before being slowed by atmospheric drag and then deploying a parachute and thrusters

October 17, 2016: A European Space Agency experimental probe is expected to land Wednesday on Mars, as part of a mission aimed at exploring the red planet’s atmosphere and searching for signs of life.

Flight director Michel Denis confirmed the Schiaparelli Mars lander had separated from its mother ship as scheduled Sunday, to applause at mission control center in Darmstadt, Germany.

As planned, the 600-kilogram probe separated from an unmanned craft called the Trace Gas Orbiter after a seven-month, 496-million-kilometer flight from Earth.

ESA said Schiaparelli will enter the atmosphere Wednesday at a speed of nearly 21,000 kilometers per hour, before being slowed by atmospheric drag and then deploying a parachute and thrusters.

Schiaparelli will take images of Mars and conduct scientific measurements on the surface, but its main purpose is to test technology for a future European Mars rover.

Meanwhile, TGO will remain in orbit, analyzing methane and other gases in the Martian atmosphere to help determine whether there is or was life on Mars.

The two crafts are part of the ExoMars mission, a joint venture between ESA and Russia’s Roscosmos space agency, and were launched in March.

In the next stage of the ExoMars program, ESA plans to send a rover to Mars in 2020, equipped with a drill and instruments dedicated to geochemistry and the search for life.

Scientists have said that landing a spacecraft on Mars is very difficult. ESA’s last attempt to land the Beagle 2 rover on Mars failed at the end of 2003.

Beagle 2 disappeared during the landing process and was declared lost after several months. It was not located until January 2015, when new photos from an orbiter showed that it had reached the surface, but did not fully deploy and start communicating. (VOA)

Scientists Track Chinese Space Station as It Falls to Earth

  • Scientists track the Chinese Space Station
  • It will fall on Earth soon
  • Scientists are trying to locate the exact location where it will fall

Scientists are monitoring a defunct Chinese space station that is expected to fall to Earth around the end of the month, the largest manmade object to re-enter Earth’s atmosphere in a decade.

The head of the European Space Agency’s debris office, Holger Krag, says China’s Tiangong-1 space station will likely fall to Earth between March 30 and April 3.

Krag said it still not yet known where the space station will hit Earth, but said it would be extremely unlikely for anyone to be injured when it does.

Injury unlikely

“Our experience is that for such large objects typically between 20 and 40 percent of the original mass, of 8.5 tons, will survive re-entry and then could be found on the ground, theoretically,” he said.

“However, to be injured by one of these fragments is extremely unlikely. My estimate is that the probability to be injured by one of these fragments is similar to the probability of being hit by lightning twice in the same year,” Krag added.

He said the space station is expected to fall between the areas of 43 degrees south and 43 degrees north, and everything outside that zone is considered safe.

“Northern Europe including France, Germany, Austria and Switzerland are definitely on the safe side. Southern Europe, the southern part of North America, South Asia, Africa, Australia and also South America are still within the zone today,” he said.

Where will it hit?

Scientists say it is hard to predict where Tiangong-1 will hit Earth in part because of its low orbit and high velocity. They say the space station is travelling 17,400 mph and orbits Earth about every 90 minutes.

Tiangong-1 was launched into orbit in 2011 as China’s first space lab. It carried out orbit experiments in preparation for China’s plan to put a permanent space station into orbit by 2023. VOA
