The International Space Station: Apex of International Collaboration

It's National Space Day! To mark the occasion, we're reflecting on the International Space Station, which has been continuously occupied since Nov. 2, 2000. As our orbiting laboratory that enables us to conduct important science off our home planet, the ISS allows researchers from all over the world to put their talents to work on innovative experiments in the microgravity environment. An international partnership of space agencies provides and operates the elements of the ISS. The principals are the space agencies of the United States, Russia, Europe, Japan and Canada. Although each space station partner has distinct agency goals for station research, each partner shares a unified goal to extend the resulting knowledge for the betterment of humanity! Here are 5 fun facts about our about our out-of-this world floating laboratory:

1. The ISS is a unique scientific platform that has enabled more than 3,600 researchers in 106 countries and areas to conduct more than 2,500 experiments in microgravity through February 2018—and the research continues. 

2. Astronauts and cosmonauts have conducted more than 205 spacewalks (and counting!) for space station construction, maintenance and repair since December 1998.

3. The station’s orbital path takes it over 90 percent of the Earth’s population, with astronauts taking millions of images of the planet below. 

4. Six spaceships can be connected to the space station at once.

5. An international crew of at most six people live and work while traveling at a speed of five miles per second, orbiting Earth about every 90 minutes.

Currently, six humans are living and working on the International Space Station, which orbits 250 miles above our planet at 17,500mph.

20 Years of the Solar and Heliospheric Observatory

The Solar and Heliospheric Observatory, SOHO for short, has captured the imagination of scientists and the public alike for two decades now. We teamed up with the European Space Agency (ESA) on SOHO, which observes the sun from space. It was launched 20 years ago this week, on Dec. 2, 1995, with the mission to study the internal structure of our neighborhood star, its atmosphere and the origin of the solar wind. SOHO sends spectacular data daily, and has led scientists to a wealth of understanding.

Here are the top 5 things you need to know about SOHO, the sun and other solar observation missions:

1. SOHO Set Out for Space with an Ambitious Mission

SOHO was designed to answer three fundamental scientific questions about the sun: What are the structure and dynamics of the solar interior? Why does the solar corona exist and how is it heated to such an extremely high temperature? Where is the solar wind produced and how is it accelerated? Clues about the solar interior come from studying seismic waves that appear as ripples on the sun's surface, a technique called helioseismology.

2. SOHO Enjoys a Great View

SOHO commands an uninterrupted view of the sun, while always staying within easy communication range of controllers at home. The space-based observatory moves around the sun in step with the Earth, by slowly orbiting around a unique point in space called the First Lagrangian Point (L1). There, the combined gravity of the Earth and sun keep SOHO in a position that's always between the sun and the Earth. The L1 point is about 1 million miles (about 1.5 million kilometers) away from Earth (about four times the distance to the Moon).

3. Bonus Discoveries: Lots of Comets

Besides watching the sun, SOHO has become the most prolific discoverer of comets in astronomical history. In September 2015, SOHO found its 3000th comet. Sometimes the spacecraft's instruments capture comets plunging to their death as they collide with the sun.

4. Extra Innings

SOHO was meant to operate until 1998, but it was so successful that ESA and NASA decided to prolong its life several times and endorsed several mission extensions. Because of this, the mission has been able to observe an entire 11-year solar cycle and much of the next.

5. Keep Your Eye (Safely) on the Sun

You can see what SOHO sees, almost in real time. The latest images from the spacecraft, updated several times daily, are available online. Take a look HERE.

Solar System: Top 5 Things to Know This Week

It’s only Tuesday and this week is already filled with news about our solar system. Here are the top five things to know this week:

1) Mars!

With five spacecraft in orbit and two rovers exploring the ground, there’s always something new and interesting about the Red Planet. Yesterday things got even more exciting when we released the most compelling evidence yet that liquid water sometimes flows on Mars today.

2) HTV-5 Cargo Ship

On Monday, the HTV-5 cargo ship was released from the International Space Station to burn up as it reenters Earth’s atmosphere. The HTV-5 carried a variety of experiments and supplies to the space station, and was docked for five weeks.

3) Pluto Continues to Excite

If you haven’t been keeping up with the weekly releases of newly downloaded pictures from our New Horizons spacecraft, you are definitely missing out. But don’t worry, we have you covered. The latest updates can be found HERE, be sure to follow along as new information is released. More images are scheduled to be featured on Oct. 1.

4) Cassini Mission

This week on Sept. 30, our Cassini spacecraft will reach the closest point to Saturn in it’s latest orbit around the planet. Just to put things in perspective, that will be Cassini’s 222nd orbit around Saturn! Learn more about this mission HERE.

5) What Happened to Mars’ Atmosphere?

Believe it or not, the Martian atmosphere we see today used to be much more substantial many years ago. What happened? Our Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft has been in orbit around Mars for one Earth year, searching for the answers. Learn more HERE.

In Roman mythology, the god Jupiter drew a veil of clouds around himself to hide his mischief. It was only Jupiter's wife, the goddess Juno, who could peer through the clouds and reveal Jupiter's true nature. ⁣ ⁣ Our @NASAJuno spacecraft is looking beneath the clouds of the massive gas giant, not seeking signs of misbehavior, but helping us to understand the planet's structure and history...⁣ ⁣ Now, @NASAJuno just published its first findings on the amount of water in the gas giant’s atmosphere. The Juno results estimate that at the equator, water makes up about 0.25% of the molecules in Jupiter's atmosphere — almost three times that of the Sun. An accurate total estimate of this water is critical to solving the mystery of how our solar system formed. 

The JunoCam imager aboard Juno captured this image of Jupiter's southern equatorial region on Sept. 1, 2017. The bottom image is oriented so Jupiter's poles (not visible) run left-to-right of frame.

Want to Send Your Art to the International Space Station?!

For children ages 4-12, we’re hosting an art contest! Get the details:

We are working with Boeing and SpaceX to build human spaceflight systems, like rockets and spacecraft, to take astronauts to the International Space Station. These companies will fly astronauts to orbit around Earth while we focus on plans to explore deeper into our solar system. 

Get out your art supplies and use your creative imagination to show us the present and future of traveling in space!

There are no grocery stores in space, but there may soon be farms. Very small farms that are important to a crew conducting a mission to deep space. That’s because our astronauts will need to grow some of their own food. Researchers on Earth and astronauts on the International Space Station are already showing what is needed to grow robust plants in orbit.

What would you take to space? Astronaut Suni Williams took a cutout of her dog, Gorbie, on her first mission to the International Space Station. 

Kids 4 to 12, draw what you would take and enter it in our Children’s Artwork Calendar contest! Your entry could be beamed to the space station!

Go to http://go.nasa.gov/2fvRLNf for more information about the competition’s themes, rules and deadlines plus the entry form. 

Get your parent's permission, of course!

Email your entry form and drawing to us at: [email protected]

Is there any other way to actually look at the eclipse (besides television/streams) without using the special eclipse glasses?

Unfortunately, you can not directly look at the eclipse without the proper eye protection https://eclipse2017.nasa.gov/safety. But there are lots of fun indirect methods that you can use. The GIF shows how you can make a pin hole projector with your hands. We also have patterns for 3D printers to make your own pin hole projector in the shape of the US or your state https://eclipse2017.nasa.gov/2d3d-printable-pinhole-projectors
