Fly Your Satellite

Every now and then I mention the opportunities for students to actually build and fly experiments including CubeSats into space. I do this in the context of NASA, but ESA also has a robust programme to help university students along the way too.

Aurora From Above

A beautiful image from the International Space Station. Here at mid- latitude the aurora is pretty rare these days; it is solar minimum after all.

If you happen to listen to short wave radio or are an amateur radio operator as I am, one of the hallmarks of an active aurora is the radio transmissions (notably the 20 meter ham band or in the area of 14 MHz) sound like they are in a bottom of a barrel. Really, check it out sometime. So I wonder how things are different from the other side of the aurora.

There are a number of sites to find out what is going on with space weather here’s one: Space Weather Prediction Center.

About the image from NASA: Aboard the International Space Station, NASA astronaut Christina Koch snapped this image of an aurora, saying: “Years ago at the South Pole, I looked up to the aurora for inspiration through the 6-month winter night. Now I know they’re just as awe inspiring from above.

ISS Transit During Eclipse

One of my favorite websites is “Smarter Every Day“. Destin always puts up interesting videos so you may want to pay the site a visit if you’ve not been there before.

This particular video includes a transit of the Sun by the ISS and a look at the Solar Eclipse of 2017. I totally “get” the excitement of catching the transit. Opportunities don’t come along very often and it has been my experience something always goes wrong. One of these days I will be successful.

ESA’s New Rides

It’s the Vega-C an updated version of the tried and true Vega offering more capacity with more power and the Ariane-6. I can’t wait to watch the Ariane-6 take off, it’s the predecessor to the powerhouse Ariane-5 heavy lift rocket.

Way to go ESA!!


Do you have any favorite music scores you listen to while traveling about? NASA has a long tradition of using music on their missions, notably to awaken space-fairing travelers.

They are looking for suggestions to add to the old eight-track player. Ok no eight-track player, some readers may not even know what that is. Just as well, but if you must know, go here.

You can still buy them (used of course).

So here you go, BE SURE TO READ THE RULES at the end!

NASA: Music has been interwoven throughout spaceflight history, from pre-launch songs to shuttle wake-up calls to crewmembers playing instruments on the International Space Station. As we celebrate the 50th anniversary of Apollo 11, we’re also preparing to go back to the Moon by 2024, which means astronauts will have a non-stop journey of approximately 3 days each way – the ultimate long-distance travel. Just like any road trip needs a soundtrack, so does a spaceflight! If you were making the journey, what favorite song would you be sure to include on your playlist? Let us add it to ours! Tell us on Twitter with the hashtag #NASAMoonTunes or submit via this form

Submit your suggestion from June 3-June 28 — the same time frame in which Apollo 11 astronauts were making final preparations for their mission 50 years ago. Liftoff of our playlist will be on July 13 and 14 and will air during a live show on NASA’s Third Rock Radio, just a few days prior to the Apollo 11 launch anniversary!

The rules:

1. Songs with explicit titles, lyrics and themes will not be accepted for addition to the playlist. NASA is for everyone – let’s make sure our playlist is too.

2. Only songs published on official music streaming services at the time of the acceptance period will be added to the playlist. A user may not submit song lyrics or unpublished music from sites such as SoundCloud, YouTube, Bandcamp, MixCloud or other user-uploaded content websites.

3. Only songs with the hashtag #NASAMoonTunes on Twitter and submissions via the above form will be accepted.

4. Third Rock Radio has the flexibility to select which songs will air from the proposed list. There is no requirement or obligation to play any specific song from the playlist, and there is no guarantee that each song submitted will be aired live. Want to know if your submission made the cut? Don’t miss the live show!

To Light Speed (Almost)

NASA: One hundred years ago, on May 29, 1919, measurements of a solar eclipse offered proof for Einstein’s theory of general relativity. Even before that, Einstein had developed the theory of special relativity, which revolutionized the way we understand light. To this day, it provides guidance on understanding how particles move through space — a key area of research to keep spacecraft and astronauts safe from radiation.

The theory of special relativity showed that particles of light, photons, travel through a vacuum at a constant pace of 670,616,629 miles per hour — a speed that’s immensely difficult to achieve and impossible to surpass in that environment. Yet all across space, from black holes to our near-Earth environment, particles are, in fact, being accelerated to incredible speeds, some even reaching 99.9% the speed of light.

Scientists suspect magnetic reconnection is one way that particles are accelerated to nearly light speed. This illustration depicts the magnetic fields around Earth, which snap and realign, causing charged particles to be flung away at high speeds. Find out all three ways that this acceleration happens.

Get Your Name On Mars2020

You can get your name on NASA’s Mars2020 rover. Super simple here’s the details:

NASA: Although it will be years before the first humans set foot on Mars, NASA is giving the public an opportunity to send their names — stenciled on chips — to the Red Planet with NASA’s Mars 2020 rover, which represents the initial leg of humanity’s first round trip to another planet. The rover is scheduled to launch as early as July 2020, with the spacecraft expected to touch down on Mars in February 2021.

The rover, a robotic scientist weighing more than 2,300 pounds (1,000 kilograms), will search for signs of past microbial life, characterize the planet’s climate and geology, collect samples for future return to Earth, and pave the way for human exploration of the Red Planet.

“As we get ready to launch this historic Mars mission, we want everyone to share in this journey of exploration,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate (SMD) in Washington. “It’s an exciting time for NASA, as we embark on this voyage to answer profound questions about our neighboring planet, and even the origins of life itself.”

The opportunity to send your name to Mars comes with a souvenir boarding pass and “frequent flyer” points. This is part of a public engagement campaign to highlight missions involved with NASA’s journey from the Moon to Mars. Miles (or kilometers) are awarded for each “flight,” with corresponding digital mission patches available for download. More than 2 million names flew on NASA’s InSight mission to Mars, giving each “flyer” about 300 million frequent flyer miles (nearly 500 million frequent flyer kilometers).

From now until Sept. 30, you can add your name to the list and obtain a souvenir boarding pass to Mars here:

A Century of Gravity

More correctly titled: “One hundred years of gravity”.

In this video, Günther Hasinger, ESA Director of Science, reflects on this historic measurement that inaugurated a century of exciting experiments, investigating gravity on Earth and in space and proving general relativity in ever greater detail. — NASA
