Nasa SpaceX Crew Return: Dragon Capsule Splashes Down



RAHUL SHARMA DEBT CONNECT IN MANCHESTER, UK,





Two American astronauts have splashed down, as the first commercial crewed mission to the International Space Station returned to Earth.

The SpaceX Dragon Capsule carrying Doug Hurley and Bob Behnken came down in the Gulf of Mexico just south of Pensacola on Florida's Gulf coast.

A recovery vessel moved in to pick up the vehicle and extricate the men.

The touchdown marks the first crewed US water landing since the final outing of an Apollo command module 45 years ago.

Hurley's and Behnken's capsule touched the water at about 14:48 EDT (19:48 BST; 18:48 GMT).

Private boats which came close to the Dragon were asked to leave amid concern over hazardous chemicals on the capsule.

Nasa administrator Jim Bridenstine said the presence of the boats "was not what we were anticipating".

"What is not common is having passersby approach the vehicle close range with nitrogen tetroxide in the atmosphere, that's not something that is good," he said. "And we need to make sure that we're warning people not to get close to the spacecraft in the future."

"It's truly our honour and privilege," said Hurley as the astronauts arrived home.

"On behalf of the SpaceX and Nasa teams, welcome back to Planet Earth. Thanks for flying SpaceX," SpaceX mission control responded.

President Donald Trump - who attended the capsule's launch two months ago - hailed its safe return.

"Thank you to all!" he tweeted. "Great to have NASA Astronauts return to Earth after very successful two month mission."

Who Was Dilhan Eryurt? Google Doodle Celebrates Turkish Astrophysicist and NASA Scientist


RAHUL SHARMA DEBT CONNECT IN MANCHESTER, UK,





Who was Dilhan Eryurt?
Professor Doctor Dilhan Eryurt was born November 29, 1926, in Izmir in the west of Turkey.

But she did not remain in her home city for long, moving firstly to Istanbul and then to the nation's capital of Ankara.

It was in high school there that she picked up a love for mathematics, eventually going on to study in the subject at university - only to gain an interest in astronomy.

After completing her studies, Eryurt helped open an astronomy department at Ankara University, before getting her doctorate there in 1953 after spending time at the University of Michigan.

She later had a two-year scholarship in Canada, the professor headed for the US, firstly to Indiana University, before working at Nasa's Goddard Space Flight Center in Maryland.

At the time, Eryurt was the only female astronomer working at the institution - and she made great breakthroughs in relation to the solar system's biggest star.

She learnt that the brightness of the Sun had decreased during its 4.5 billion years lifespan, meaning it was warmer and brighter in the past.

This influenced research into space flights at the time - before later receiving the Apollo Achievement Award for her work in helping to model the solar impact on the lunar environment for Apollo 11's Moon landing mission.
