10 Ways To BBQ On An Alien World

International Space Station

The International Space Station is an important and special place that is built on international cooperation and partnership. The station is a convergence of science, technology and human innovation that benefits and advances our global community here on Earth.

While the space station is an important aspect of our low-Earth orbit exploration, it is also the key to our next giant leap to deep space and our Journey to Mars. For example, our recent VEGGIE experiment aboard the space station is a critical aspect of long-duration exploration missions farther into the solar system. Food grown in space will be a resource for crew members that can provide them will essential vitamins and nutrients that will help enable deep space pioneering.

Another important experiment underway is the Twins Study that involves twin astronauts Scott and Mark Kelly. These investigations will provide insight into the subtle effects and changes that may occur in spaceflight as compared to Earth by studying two individuals who have the same genetics, but are in different environments for one year. You can follow Scott Kelly as he spends a year in space.

The space station is the second brightest object in the sky (after the moon, of course), and you don’t even need a telescope to see it! We can even tell you exactly when and where to look up to Spot the Station in your area!

So, as you look to spot the station in the sky, remember that even though it may look small from Earth, the crew onboard (and at home) are making contributions to international partnerships and global research.

It's a long ways down. This is a view from the vantage point of astronaut Shane Kimbrough during his spacewalk last Friday outside the International Space Station. Shane posted this photo and wrote, " View of our spectacular planet (and my boots) during the #spacewalk yesterday with @Thom_astro." During the spacewalk with Kimbrough and Thomas Pesquet of ESA, which lasted just over six-and-a-half hours, the two astronauts successfully disconnected cables and electrical connections to prepare for its robotic move Sunday, March 26.

Two astronauts will venture outside the space station again this Thursday, March 30 for the second of three spacewalks. Kimbrough and Flight Engineer Peggy Whitson will begin spacewalk preparation live on NASA Television starting at 6:30 a.m. EST, with activities beginning around 8 a.m. Watch live online here.

5 NASA Software Codes You Can Download – For Free!

One of the biggest steps of any mission starts right here on Earth at a computer desk – NASA runs on software, period. Rovers can’t move, spacecraft can’t fly, even rockets can’t blast off without the software codes that run them all.

We’ve compiled hundreds of these powerful codes into one location at software.nasa.gov. And guess what? You can start downloading them right now for free! Here are just a few you can use:  

1. TetrUSS (Tetrahedral Unstructured Software System)

TetrUSS has been used extensively for space launch vehicle analysis and design, like on the Space Launch System, which is planned to take humans to Mars.

You really could say it's helping us to “blast off.” Outside of NASA, this software has been used to analyze Mars planetary entry vehicles, ballistics and even high-altitude sky diver aerodynamics. Basically if anything has moved through any planetary atmosphere, this software has played a role.

2. KNIFE (part of the FUN3D software and released as a package)

The name may be a bit intimidating, but with good reason – KNIFE packs a powerful punch. 

It was created to help us learn more about the sonic booms that resonate when planes break the sound barrier, but it has also helped develop green energy sources such as wind turbines and techniques to minimize drag for long-haul trucking. Maybe we should re-name this versatile and handy code, “Swiss Army KNIFE?”

3. Cart3D (Automated Triangle Geometry Processing for Surface Modeling and Cartesian Grid Generation)

If software codes went to high school, Cart3D would be Prom Queen. This software is so popular, it is being used in almost every mission area here at NASA. 

Engineers and scientists are currently using it to model everything from advanced drones to quieter supersonic aircraft.

4. FACET (Future Air Traffic Management Concepts Evaluation Tool)

Frequent flyers: this may be your favorite code without even knowing it. FACET was developed to evaluate futuristic concepts in air traffic management, and it has served as a testbed for assessing today’s regular operations. 

To sum it up, this software code helps airports keep planes organized in the air and on the ground.

5. GIPSY-OASIS

GIPSY-OASIS is part of the GPS system to end all GPS systems. It’s so accurate, John Deere used it to help create self-driving tractors.

 How? John Deere already had a navigation system in the works, but it could only be used in certain parts of the world. 

Our ground stations are all across the globe, and our software ensures accuracy down to a few inches. And so, a new breed of tractor was born!  Did we mention this software is free?

These are just a few examples of the software NASA has available for free public and consumer use. To browse the catalog online, check out software.nasa.gov.

Solar System: Things to Know This Week

Here are a few things you should know about our solar system this week:

1. Gearing Up for a Grand Finale

There’s just a year left until the Cassini mission begins its Grand Finale – the final phase of its mission, during which the spacecraft will dive repeatedly between the planet and the rings. To get ready, the Cassini team has launched an enhanced, mobile device-friendly version of the mission website. The site includes information about Cassini, Saturn, the moons and the rings – but it also tells the human stories behind one of the most ambitions expeditions of all time.

2.Caught in Transit

On Monday, May 9, the planet Mercury will cross directly in front of the sun, an event that hasn’t occurred since 2006 and won’t happen again until 2019. Find out how to watch HERE.  

3. A Moon for Makemake

Our Hubble Space Telescope has spotted a small, dark moon orbiting Makemake (pronounced “MAH-kay MAH-kay). Make make is the second brightest icy dwarf planet – after Pluto – in the faraway Kuiper Belt.

4. The Age of the Aquarids

The Eta Aquarid meteor shower is the first of two showers that occur each year as a result of Earth passing through dust released by Halley’s Comet. This year, it should peak on the night of May 5/6. Get tips for watching HERE.

5. The Southern Lights of Saturn

On May 4, Cassini will reach periapse, the closest point to Saturn in the spacecraft’s orbit. At about this time, Cassini’s cameras will monitor Saturn’s south polar aurorae, and also image the bright limb of the planet to better understand its upper haze layers.

3. Launch-iversaries!

We’re celebrating two launch anniversaries. Before Curiosity. Before Spirit and Opportunity, there was Pathfinder and the hardy Sojourner rover, launched on Dec. 4, 1996. Pathfinder was a demonstration of the technology necessary to deliver a lander and a free-ranging robotic rover to the surface of Mars in a cost-effective and efficient manner. The lander, formally named the Carl Sagan Memorial Station following its successful touchdown, and the rover, named Sojourner after American civil rights crusader Sojourner Truth, both outlived their design lives — the lander by nearly three times, and the rover by 12 times! We continued the tradition with Spirit and Opportunity. Now there is the Mars Science Laboratory (with the Curiosity rover in stowage), which was launched on Nov. 26, 2011. It landed successfully in Gale Crater at 1:31 am EDT on Aug. 6, 2012.

Glacier Turns into a ‘Snow Swamp’

In just four days this summer, miles of snow melted from Lowell Glacier in Canada. Mauri Pelto, a glaciologist at Nichols College, called the area of water-saturated snow a “snow swamp.”

These false-color images show the rapid snow melt in Kluane National Park in the Yukon Territory. The first image was taken on July 22, 2018, by the European Space Agency’s Sentinel-2; the next image was acquired on July 26, 2018, by the Landsat 8 satellite.

Ice is shown as light blue, while meltwater is dark blue. On July 26, the slush covered more than 25 square miles (40 square km).

During those four days, daily temperatures 40 miles (60 km) northeast of the glacier reached 84 degrees Fahrenheit (29 degrees Celsius) — much higher than normal for the region in July.

Science When the Sun Don’t Shine

About once a year, somewhere on Earth, the sun is blocked by the moon. This phenomenon – called a total solar eclipse – is one of the most beautiful natural events.

Blocking the light of the sun during a total solar eclipse reveals the sun's relatively faint, feathery atmosphere, called the corona. The corona is one of the most interesting parts of the sun. We usually study it using an instrument called a coronagraph, which uses a solid disk to make an artificial eclipse by blocking the sun’s face.

To successfully block all of the sun's bright light – which can bend around the sharp edges of a coronagraph disk – coronagraphs must block much more than just the face of the sun.  So total solar eclipses are a rare chance to study the lower part of the corona, close to the surface of the sun.   

We have sent a team of scientists to Indonesia, where they’re preparing for an experiment during the March 8, 2016, eclipse, visible from Southeast Asia.

The scientists are measuring a certain kind of light – called polarized light – scattered by electrons in the lower corona, which will help us understand the temperature and speed of these electrons.

The March 8 eclipse is a preview of the total solar eclipse that will be visible across the US in August 2017.

Remember, you should never look directly at the sun – even if the sun is partly obscured. This also applies during a total eclipse up until the time when the sun is completely and totally blocked. More on safety: http://go.nasa.gov/1L6xpnI

NASA: 2016 Look Ahead

The work we do, and will continue in 2016, helps the United States maintain its world leadership in space exploration and scientific discovery. Here’s an overview of what we have planned for the coming year:

Our Journey to Mars

We’re developing the capabilities needed to send humans to an asteroid by 2025 and Mars in the 2030s. Mars is a rich destination for scientific discovery and robotic and human exploration as we expand our presence into the solar system. Its formation and evolution are comparable to Earth, helping us learn more about our own planet’s history and future.

Work and Research on the International Space Station

The International Space Station is a unique place – a convergence of science, technology and human innovation that demonstrates new technologies and makes research breakthroughs not possible on Earth. In 2016, we will continue our groundbreaking research on the orbiting laboratory.

Returning Human Spaceflight Launches to American Soil

Our Commercial Crew Program is working with the American aerospace industry as companies develop and operate a new generation of spacecraft and launch systems capable of carrying crews to low-Earth orbit and the International Space Station. Commercial transportation to and from the station will provide expanded utility, additional research time and broader opportunities of discovery on the orbiting laboratory.

Studying Our Earth Right Now

We use the vantage point of space to increase our understanding of our home planet, improve lives and safeguard our future. In 2016, we will continue to monitor Earth’s vital signs from land, air and space with a fleet of satellites and ambitious airborne and ground-based observation campaigns.

Fostering Groundbreaking Technology Development

Sustained investments in NASA technology advances our space exploration, science and aeronautics capabilities. Our technology development also supports the nation's innovation economy by creating solutions that generate tangible benefits for life on earth. In 2016, we will continue to invest in the future of innovation.

Breakthroughs in Aeronautics

Thanks to our advancements in aeronautics, today’s aviation industry is better equipped than ever to safely and efficiently transport all those passengers to their destinations. In fact, every U.S. aircraft flying today and every U.S. air traffic control tower uses NASA-developed technology in some way. In 2016, we will continue making these breakthroughs in aeronautics.

Discoveries in Our Solar System and Beyond

This year we will continue exploring our solar system and beyond to unravel the mysteries of our universe. We are looking to answer key questions about our home planet, neighboring planets in our solar system and more!
