Jumping on Earth vs jumping on the Moon

Fibonacci you crazy bastard….

As seen in the solar system (by no ridiculous coincidence), Earth orbits the Sun 8 times in the same period that Venus orbits the Sun 13 times! Drawing a line between Earth & Venus every week results in a spectacular FIVE side symmetry!!

Lets bring up those Fibonacci numbers again: 1, 1, 2, 3, 5, 8, 13, 21, 34..

So if we imagine planets with Fibonacci orbits, do they create Fibonacci symmetries?!

You bet!! Depicted here is a:

2 sided symmetry (5 orbits x 3 orbits)

3 sided symmetry (8 orbits x 5 orbits)

5 sided symmetry (13 orbits x 8 orbits) - like Earth & Venus

8 sided symmetry (21 orbits x 13 orbits)

I wonder if relationships like this exist somewhere in the universe….

LIFTOFF!

On July 7, three crew members launched from Earth; headed to their new home on the International Space Station. 

Crewmembers Kate Rubins of NASA, Anatoly Ivanishin of Roscosmos and Takuya Onishi of the Japan Aerospace Exploration Agency (JAXA) will spend approximately four months on the orbital complex, returning to Earth in October.

Five Things to Know About NASA Astronaut Kate Rubins

Among the newest crew on the International Space Station is U.S. astronaut Kate Rubins, who will assume the role of Flight Engineer for Expeditions 48 and 49. Here are five things you should know about her:

1. She was chosen from a pool of over 3,500 applicants to receive a spot on our 2009 astronaut training class.

After being selected, Rubins spent years training at Johnson Space Center to become an astronaut. She learned how to use the complex station systems, perform spacewalks, exercise in space and more. Some training even utilized virtual reality.

2. She has a degree in cancer biology.

After earning a Bachelor of Science degree in Molecular Biology from the University of California, San Diego in 1999, Rubins went on to receive a doctorate in Cancer Biology from Stanford University Medical School Biochemistry Department and Microbiology and Immunology Department in 2005. In other words, she’s extremely smart.

3. Her research has benefited humanity.

Rubins helped to create therapies for Ebola and Lassa viruses by conducting research collaboratively with the U.S. Army. She also aided development of the first smallpox infection model with the U.S. Army Medical Research Institute of Infectious Diseases and the Centers for Disease Control and Prevention. NBD. It will be exciting to see the research come out of a mission with a world-class scientist using a world-class, out-of-this-world laboratory!

4. She is scheduled to be the first person to sequence DNA in space.

During her time at the space station, Rubins will participate in several science experiments. Along with physical science, Earth and space science and technology development work, she will conduct biological and human research investigations. Research into sequencing the first genome in microgravity and how the human body’s bone mass and cardiovascular systems are changed by living in space are just two examples of the many experiments in which Rubins may take part.

5. In her spare time, she enjoys scuba diving and triathlons…among other things.

Rubins was on the Stanford Triathlon team, and also races sprint and Olympic distance. She is involved with health care/medical supply delivery to Africa and started a non-profit organization to bring supplies to Congo. Her recent pursuits involve flying airplanes and jumping out of them – not simultaneously. 

Rubins is scheduled to arrive at the International Space Station at 12:12 a.m. Saturday, July 9. After her launch on Wednesday, July 6, the three crew members traveled 2 days before docking to the space station’s Rassvet module. 

Watch live coverage of docking and their welcoming starting at 11:30 p.m. EDT Friday, July 8 on NASA Television.

The history of Hubble - Η ιστορία του διαστημικού τηλεσκοπίου που έχει γράψει ιστορία με τις φωτογραφίες του, Hubble.

Can You #SpotHubble?

Hey Tumblr! We’re Inviting You to #SpotHubble

Since its launch in 1990, the Hubble Space Telescope has sent back mind-blowing images that not only changed our understanding of our universe, but also changed where we see our universe.

Hubble is more than a science instrument; it’s a cultural phenomenon! Take a moment to think about where you’ve seen the Hubble Space Telescope or Hubble images in your daily life. 

Maybe you walk by a mural inspired by Hubble images everyday on your way to work. 

Perhaps you’ve even created art based on Hubble images.

We want to see the Hubble impact in your life! Share your photos with us on Instagram, Twitter, Flickr and Facebook. If a #SpotHubble image catches our eye, we may share your post on our NASA Hubble social media accounts.

Here’s how to #SpotHubble!

There are four social media platforms that you can use to submit your work:

Flickr: Submit your photos to the Spot Hubble Flickr Group

Instagram: Use the Instagram app to upload your photo, and in the description include #SpotHubble and #NASAGoddard

Twitter: Share your image on Twitter and include #SpotHubble in the tweet

Facebook: Share your image on Facebook and include #SpotHubble in the post

Please note, submissions are subject to certain terms and conditions.

Juno: Inside the Spacecraft

Our Juno spacecraft was carefully designed to meet the tough challenges in flying a mission to Jupiter: weak sunlight, extreme temperatures and deadly radiation. Lets take a closer look at Juno:

It Rotates!

Roughly the size of an NBA basketball court, Juno is a spinning spacecraft. Cartwheeling through space makes the spacecraft’s pointing extremely stable and easy to control. While in orbit at Jupiter, the spinning spacecraft sweeps the fields of view of its instruments through space once for each rotation. At three rotations per minute, the instruments’ fields of view sweep across Jupiter about 400 times in the two hours it takes to fly from pole to pole.

It Uses the Power of the Sun

Jupiter’s orbit is five times farther from the sun than Earth’s, so the giant planet receives 25 times less sunlight than Earth. Juno will be the first solar-powered spacecraft we’ve designed to operate at such a great distance from the sun. Because of this, the surface area of the solar panels required to generate adequate power is quite large.

Three solar panels extend outward from Juno’s hexagonal body, giving the overall spacecraft a span of about 66 feet. Juno benefits from advances in solar cell design with modern cells that are 50% more efficient and radiation tolerant than silicon cells available for space missions 20 years ago. Luckily, the mission’s power needs are modest, with science instruments requiring full power for only about six out of each 11-day orbit.

It Has a Protective Radiation Vault

Juno will avoid Jupiter’s highest radiation regions by approaching over the north, dropping to an altitude below the planet’s radiation belts, and then exiting over the south. To protect sensitive spacecraft electronics, Juno will carry the first radiation shielded electronics vault, a critical feature for enabling sustained exploration in such a heavy radiation environment.

Juno Science Payload:

Gravity Science and Magnetometers – Will study Jupiter’s deep structure by mapping the planet’s gravity field and magnetic field.

Microwave Radiometer – Will probe Jupiter’s deep atmosphere and measure how much water (and hence oxygen) is there.

JEDI, JADE and Waves – These instruments will work to sample electric fields, plasma waves and particles around Jupiter to determine how the magnetic field is connected to the atmosphere, and especially the auroras (northern and southern lights).

JADE and JEDI

Waves

UVS and JIRAM – Using ultraviolet and infrared cameras, these instruments will take images of the atmosphere and auroras, including chemical fingerprints of the gases present.

UVS

JIRAM

JunoCam – Take spectacular close-up, color images.
