The Hayabusa 2 spacecraft briefly touched down on asteroid Ryugu on Feb. 21, 2019, in order to collect samples by firing a bullet into the surface.

Descent was relatively slow, but it looks much faster in the video released by the Japan Aerospace Exploration Agency because it runs at five times normal speed. Because of the low gravity, when the 4.4-pound (2-kilogram) projectile fired into the surface, ejecta quickly encompassed the whole camera view.

Hovering at a position of about 28 feet (8.5 meters), the spacecraft let itself free fall to the surface. Once the bullet was fired with samples hopefully collected inside the sampling device, the spacecraft fired thrusters to climb back out of the asteroids tiny gravity well.

According to JAXA, the Hayabusa 2 team is confident samples were collected. However, another touch-and-go attempt is planned for April. The hope is for up to 100 milligrams of material to be brought back to Earth by December of 2020.

Hayabusa 2 is slated to stay in orbit around the asteroid until December 2019. The 1,300-pound (600-kilogram) spacecraft was launched in December 2014 and achieved orbit around Ryugu in June 2018.

Derek Richardson has a degree in mass media, with an emphasis in contemporary journalism, from Washburn University in Topeka, Kansas. While at Washburn, he was the managing editor of the student run newspaper, the Washburn Review. He also has a blog about the International Space Station, called Orbital Velocity. He met with members of the SpaceFlight Insider team during the flight of a United Launch Alliance Atlas V 551 rocket with the MUOS-4 satellite. Richardson joined our team shortly thereafter. His passion for space ignited when he watched Space Shuttle Discovery launch into space Oct. 29, 1998. Today, this fervor has accelerated toward orbit and shows no signs of slowing down. After dabbling in math and engineering courses in college, he soon realized his true calling was communicating to others about space. Since joining SpaceFlight Insider in 2015, Richardson has worked to increase the quality of our content, eventually becoming our managing editor. @TheSpaceWriter

How so, what makes you say fake without any real evidence, and the usual addage of it’s CGI just won’t cut it without overwhelming evidence to say it is fake, are you a flat earther by any chance.
