Bringing Fun To You

How could they have brought back moon rocks and moon dust? Wouldn’t ANYTHING on the moon that is loose not float away into outer space? C’mon! Have humans really ever been on the moon?

NASA astronauts Danny Olivas and Nicole Stott began the first of three spacewalks to help ready the $100 billion International Space Station for full-time science operations.

In this episode of “NASA Behind the Scenes,” astronaut Mike Massimino continues his visit with safety divers and flight doctors at the Johnson Space Center’s Neutral Buoyancy Laboratory as they compare underwater training to what it’s like to work in space. Also, members of NASA’s shuttle closeout crew go into greater depth with Mike about strapping in the astronauts before liftoff.

Astronauts Cady Coleman and Suni Williams conduct an underwater practice spacewalk session at Johnson Space Center’s Neutral Buoyancy Laboratory. The session was used to help International Space Station team members identify challenges that will need to be addressed when Expedition 24 astronauts Doug Wheelock and Tracy Caldwell Dyson perform the first of two planned spacewalks to replace a failed ammonia pump module.

With the third and final spacewalk completed Sunday, the Expedition 17 and STS-124 crews are heading into the home stretch of their joint mission. The crew members maneuvered the newly activated robotic arm on the Kibo laboratory to its stowed position Monday. They also performed a checkout of the arm’s brakes. The crews also worked in the Quest airlock of the International Space Station to replace battery charger modules. The modules charge the batteries that provide power to US spacesuits during spacewalks. Flight managers elected to replace the modules, which have shown slightly increased toxicity levels due to their age. The shuttle and station crews took a break from their activities around 5 pm EDT for the traditional joint crew news conference. Credit: NASATV

NASA Public Affairs Officer Amiko Kauderer talks with NASA Medical Flight Officer Steve Gilmore about the role of a flight surgeon in tracking astronaut health and coordinating crew medical experiments before, during and after spaceflight. Flight surgeons are involved in all phases of a human spaceflight mission, including walking the crew members through the process of becoming medically cleared for flight, coordinating the medical experiments the astronauts perform aboard the station, maintaining contact with the astronauts during spaceflight to keep track of any health issues, assuring that crew members are physically prepared for strenuous spacewalks and assisting with their rehabilitation and adaptation to gravity after they return to Earth. Gilmore became interested in becoming a flight surgeon while assigned to a rotation at Kennedy Space Center during medical school. “I had the opportunity to see a few launches, a couple of landings,” said Gilmore, “and thought it looked like a really interesting field to get into.” Questions?

They did not bring it back with them. Also, why can’t we see the rover and the U.S. flag with a telescope. If they, NASA, wanted to shut the mouths of skeptics, why don’t they simply send an unmanned craft, somewhat like a rover they sent to Mars, and take pictures of the flag and rover if they are truly there?

The moon’s gravity is only 1/6 that of earth’s. It’s not like they were going to fall and break their necks. Why didn’t they just float out or jump up when going back into the LM? Yet, they used every step of the way.

The distance to the moon can be found with the help of mirrors left on the moon by astronauts. A pulse of light is sent to the moon and returns to Earth in 2.562 s. Using the defined speed of light, calculate the distance from Earth to the moon.Please help.
Thanks.
