At the jumper's fastest point, the acceleration is by definition zero. That is because the jumper is going from speeding up to slowing down. At this instant then there is no change in the jumper's velocity. This is counter-intuitive for a lot of people because it's easy to confuse velocity with acceleration. Velocity is how fast something goes while acceleration is the rate at which velocity changes.

http://www.youtube.com/spacelab gives you an opportunity to design an experiment to be performed in space! If you're between the ages of 14-18, make a 2 minute youtube video proposing an experiment to be performed in zero g. Your video will be assessed by a panel of experts with the winner having their experiment performed in space and broadcast live to the world.

Do we need more diversity in online video?

Pioneering NASA mathematician Katherine Johnson has died at the age of 101. Johnson was part of a group of African-American women who worked on critical mathematical calculations in the early days of human spaceflight, as chronicled in the best-selling book and hit movie “Hidden Figures.”

"She was an American hero and her pioneering legacy will never be forgotten,” said NASA Administrator Jim Bridenstine.

Get ready for liftoff to the Sun! ?

Solar Orbiter, a collaboration between European Space Agency and NASA, is launching Sunday, Feb. 9, to study the inner workings of our nearest star. Tune in for launch coverage starting at 10:30 p.m. on Sunday, Feb. 9 to see liftoff, currently targeted for 11:03 p.m. EST.

NASA is preparing to send a chimpanzee, Ham, into space to test the effects of space on a living creature. He’s received a training regiment to prepare him for the mission ahead.

From the Series: Apollo's Moon Shot: Rocket Fever http://bit.ly/2MHAm4y

This year, NASA is building momentum across the agency and across every mission. This is a year of action. With each milestone, NASA is preparing to go farther than ever before.
NASA is going to the Moon and on to Mars, in a measured, sustainable way. Working with U.S. companies and international partners, NASA will push the boundaries of human exploration forward to the Moon. NASA is working to establish a permanent human presence on the Moon within the next decade to uncover new scientific discoveries and lay the foundation for private companies to build a lunar economy. We inspire generations and change the course of history as we realize the next great scientific, economic and technical achievements in space.

In the next eight minutes, you’ll experience a twenty-five-and-a-half-day mission from roll-out to recovery of the first integrated flight test of NASA’s Orion spacecraft and the Space Launch System rocket, launching from the agency’s Kennedy Space Center in Florida. This uncrewed mission will be the first in a planned series of exploration missions beyond the moon, signaling what astronauts who dare to operate in deep space will experience on future flights.

Aboard the International Space Station, Expedition 62 Flight Engineer Jessica Meir of NASA discussed the revolutionary Zero-G oven recently used on the orbital outpost during an in-flight question and answer session Feb. 19 with students from the East Middle School in Grand Blanc, Michigan. The oven was launched on a Northrop Grumman Cygnus cargo ship last November, and, along with cookies baked in the oven, was returned to Earth in January on a SpaceX/Dragon resupply vehicle.

Let’s say you’re on an interplanetary mission to Mars, millions of miles from the nearest hospital, and something in your body goes awry. Say, a routine body scan reveals a potentially life-threatening blood clot. What on Earth, or in space I guess, do you do? Well now we have the answer to that question.

NASA Flight Surgeon Explains How to Treat a Blood Clot in Space | WIRED

The High Definition Earth-Viewing (HDEV) experiment on the International Space Station has experienced a loss of data, and ground computers are no longer receiving communications from the payload. A team of engineers are reviewing the available health and status information from HDEV to identify what may have occurred. Additional updates will be published as they become available.

Tune in as Boeing's uncrewed Starliner spacecraft lands at White Sands, New Mexico. Landing is scheduled at 7:57 a.m. EST on Sunday, Dec. 22. After its launch on Dec. 20, the Starliner did not reach the planned orbit and will not dock to the International Space Station. Teams worked quickly to ensure the spacecraft was in a stable orbit and preserved enough fuel for a landing opportunity.

What's different about sleeping in space? Former NASA astronaut Mike Massimino breaks down all the differences between sleeping on Earth and sleeping in space. Is there a difference between sleeping upside down and sleeping right-side up? Do you get your own bedroom? What kind of alarm clock does an astronaut use?

Mike Massimino is a former NASA astronaut, senior advisor for space programs at the Intrepid Museum, and professor at Columbia University.

Letra de Mi mundo necesita de ti de Daniel Calveti
Se que tienes, mucho que atender
Pero mi mundo se destruye y no sabemos que hacer…

Alguien me dijo, que una oración la diferencia puede hacer
Por eso vine a ti
Por que este mundo es mi casa, necesitamos de ti…

Tengo fe en ti, creo que las cosas, pueden cambiar
El mundo llora aquí pero tú nos puedes volver hacer reír……

//tu que estas allá y nosotros aquí
Ven visítanos te ruego haz nos sonreír…//

Tengo fe en ti, creo que las cosas, pueden cambiar
El mundo llora aquí pero tú nos puedes volver hacer reír……

Tú que estas allá y nosotros aquí
Ven visítanos te ruego haz nos sonreír…

Tú que estas allá y nosotros aquí
Ven visítanos te ruego haz nos sonreír…

Tú que estas allá….
