Solar System: Things to Know This Week

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

1. The Bright and the Beautiful

In its lowest-altitude mapping orbit, at a distance of 240 miles (385 kilometers) from Ceres, Dawn has provided scientists with spectacular views of the dwarf planet, especially of its bright, young, hexagonal craters like Haulani.

2. Mars Needs Brains

NASA is soliciting ideas from U.S. industry for designs of a Mars orbiter for potential launch in the 2020s. The satellite would provide advanced communications and imaging, as well as robotic science exploration, in support of NASA's Journey to Mars. This effort seeks to take advantage of industry capabilities to improve deep space, solar electric propulsion-enabled orbiters.

3. Seeing Double

NASA measured a solar flare from two different spots in space, using three solar observatories. During a December 2013 solar flare, three sun-observing spacecraft captured the most comprehensive observations ever of an electromagnetic phenomenon called a current sheet.

4. Set a Course for Europa

This artist's rendering shows NASA's Europa mission spacecraft, which is being developed for a launch in the 2020s. The mission would place a spacecraft in orbit around Jupiter in order to perform a detailed investigation of the giant planet's moon Europa—a world that shows strong evidence for an ocean of liquid water beneath its icy crust and which could host conditions favorable for life.

5. Go Deep

Jupiter is huge, powerful and spectacular. But what lies hidden inside the giant planet? The Juno mission arrives at Jupiter in July to help us find out. Join Dr. Fran Bagenal to learn more about the mission and how it plans to delve deep into Jupiter's secrets this year.

What are CubeSats?

CubeSats are a class of research spacecraft called nanosatellites. They provide low-cost opportunities for small satellite payloads to fly on rockets planned for upcoming launches. Small satellites, including CubeSats, are playing an increasingly larger role in exploration, technology demonstration, scientific research and educational investigations here at NASA. 

Fourteen miniature satellites were deployed from the International Space Station earlier this week. Two of the CubeSats were Danish and have communication and ship signal tracking capabilities. The remaining are Dove satellites from Planet Labs and will take images of Earth from space.

On Thursday, Oct. 8, thirteen CubeSats are scheduled to launch aboard a United Launch Alliance Atlas V rocket at 8:49 a.m. EDT. Watch live on NASA TV starting at 8:29 a.m. http://www.nasa.gov/nasatv

To learn more about tomorrow’s launch, watch NASA Television today, Oct. 7 at 1 p.m. and 2 p.m. EDT. The briefings will highlight the growing importance of CubeSats in space exploration.

ICYMI: New sounds from Mars dropped! Turn the volume up to hear our Ingenuity Mars Helicopter flying on the Red Planet.

Captured by our Perseverance Mars Rover, this is the first time a spacecraft on another planet has recorded the sounds of a separate spacecraft. In this audio track, Perseverance used its SuperCam microphone to listen to the Ingenuity helicopter on April 30, 2021 as it flew on Mars for the fourth time.

With Perseverance parked 262 feet (80 meters) from the helicopter’s takeoff and landing spot, the mission wasn’t sure if the microphone would pick up any sound of the flight. Even during flight when the helicopter’s blades are spinning at 2,537 rpm, the sound is greatly muffled by the thin Martian atmosphere. It is further obscured by Martian wind gusts during the initial moments of the flight. Listen closely, though, and the helicopter’s hum can be heard faintly above the sound of those winds.

What caused this outburst of this star named V838 Mon? For reasons unknown, this star’s outer surface suddenly greatly expanded with the result that it became the brightest star in the entire Milky Way Galaxy in January 2002. Then, just as suddenly, it faded. A stellar flash like this had never been seen before – supernovas and novas expel matter out into space.

Although the V838 Mon flash appears to expel material into space, what is seen in the above GIF from the Hubble Space Telescope is actually an outwardly moving light echo of the bright flash.

In a light echo, light from the flash is reflected by successively more distant rings in the complex array of ambient interstellar dust that already surrounded the star. V838 Mon lies about 20,000 light years away toward the constellation of the unicorn (Monoceros), while the light echo above spans about six light years in diameter.

Jupiter’s vibrant bands of light belts and dark regions appear primed for their close-up during our Juno spacecraft’s 10th flyby on Feb. 7. This flyby was a gravity science positioned pass. During orbits that highlight gravity experiments, Juno is positioned toward Earth in a way that allows both transmitters to downlink data in real-time to one of the antennas of our Deep Space Network. All of Juno’s science instruments and the spacecraft’s JunoCam were in operation during the flyby, collecting data that is now being returned to Earth. The science behind this beautifully choreographed image will help us understand the origin and structure of the planet beneath those lush, swirling clouds.

Prepare to be mesmerized… 😵‍💫

Feast your eyes on the magnificent galaxy M51, also known as the Whirlpool Galaxy! This hypnotic spiral galaxy was captured in visible light with Hubble’s Advanced Camera for Surveys. Living up to its nickname, the Whirlpool Galaxy has the traits of a typical spiral galaxy, like beautifully curving arms, pink star-forming regions, and brilliant blue strands of star clusters.

The Whirlpool Galaxy is located about 31 million light-years away in the constellation Canes Venatici.

Discover more about the Whirlpool Galaxy here.

Right now, the Hubble Space Telescope is exploring #GalaxiesGalore! Find more galaxy content and spectacular new images by following along on Hubble’s Twitter, Facebook, and Instagram.

What’s Up for December?

View Mars right now, and prepare for 2016, the best Mars viewing year since 2005! Last month early risers watched small, reddish Mars dance with brighter Jupiter and Venus just before sunrise. 

This month Mars rises earlier-by about 2 a.m. local time. Its reddish color is unmistakable, even without a telescope. It's easy to see below the Moon and Jupiter on December 4. You won't see many features this month, because the planet is almost 10 times smaller than nearby Jupiter appears and 350 times smaller than the Moon appears to us on Earth.

You should also be able to see Mars' north polar region this month, because it's currently tilted towards Earth. 

You'll be amazed at the changes you'll see during 2016. January through December are all prime Mars observing months. Between January and May next year, Mars triples in apparent diameter as its orbit around the sun brings it closer to Earth. You'll even be able to see the areas on Mars where NASA's Mars landers are located.

By October, Mars shrinks in apparent size to less than half its May diameter as it speeds away from Earth. Mars shrinks even further from October through December, returning to the same size we saw in January 2016 by year's end.

So put Mars viewing on your calendar for 2016. You won't see Mars this size again until 2018, when Mars will put on an even better show.

Space Stamps

Coming in to a post office near you: new “Views of Our Planets: Forever stamps featuring iconic images of the planets in our solar system, including the well-known “Blue Marble” photo of Earth.

New “Pluto Explored” Forever stamps commemorating the July 2015 flyby of Pluto by our New Horizons spacecraft are also being issued for online purchase.

The May 31 first-day-of-issue dedication ceremony for the Pluto and planetary stamps will be in New York City at the World Stamp Show. This international gathering of stamp collectors occurs only once each decade in the United States, and – with more than 250,000 visitors expected to attend – is the largest stamp show in the world.

The Pluto stamps are of special significance to the New Horizons team, which placed a 20-cent 1991 “Pluto: Not Yet Explored” stamp on board the spacecraft. On July 14, 2015, New Horizons carried the stamp on its history-making journey to Pluto and beyond, as jubilant members of the mission team celebrated with a large print, striking the words “not yet.”

The above pane of 16 Forever stamps, the Postal Service showcases some of the more visually compelling historic, full-disk images of the planets obtained during the last half-centruy of our space exploration. Eight new colorful Forever stamps – each shown twice – feature Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

This isn’t the first time that space has been featured on postal stamps. In the past, many different space images and missions have been highlighted on the tiny pieces of paper you stick on the corner of your mail.

Here’s a look at a few space stamps of the past:

Nebulae

Stamps depicting multiple nebulae seen by the Hubble Space Telescope were released in 2000. 

Pioneer 10 

Launched in 1972, Pioneer 10 was the first spacecraft to travel through the asteroid belt and obtain close-ups of Jupiter

U.S. Launches Satellites 

This stamp, released in 1999, depicts the post World War II race in space exploration. 

Alan Shepard: First American in Space

This stamp, released in 2011, featured Alan Shepard, the first American in space. Flying on the Mercury spacecraft, Shepard launched, flew 116 miles high and came back to Earth. His flight lasted about 15 and a half minutes. 

MESSENGER Mission

MESSENGER, launching in 2004, was the first spacecraft to orbit Mercury. This stamp, released in 2011, highlighted this mission and its importance. Understanding Mercury and how it formed is critical to better understanding the conditions on and evolution of the inner planets.

The new “Views of our Planets” stamps will be widely available across the U.S. at post offices and for online purchase beginning May 31. The Pluto – Explored Forever stamps will only be sold online or by calling 800-782-6724.

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.
