8 Things To Know About Our Commercial Crew Program

What’s Up November 2017

What’s Up For November?

Dawn pairing of Jupiter and Venus, Moon shines near star clusters, meteor activity all month long!

This month binoculars will come in handy--to view the moon, star clusters, and a close pairing of Venus and Jupiter.

You can’t miss bright Venus in the predawn sky. This month Venus pairs up with Jupiter on the morning of November 13th.

The Leonids peak on a moonless November 17th. Expect no more than 10 meteors an hour around 3:00 a.m., the height of the shower.

The Northern and Southern sub-branches of the Taurid meteor shower offer sparse counts of about 5 meteors per hour, but slow, bright meteors are common.

The nearby November Orionids peak on the 28th. In contrast to the Taurids, the Orionids are swift. But don’t expect more than 3 meteors per hour.

The moon glides by three beautiful star clusters in the morning sky this month, and a pair of binoculars will allow you to see the individual stars in the clusters. Aim your binoculars at the Pleiades and the moon on the 5th.

Then aim at the Messier or M-35 cluster and the moon on the 7th and the Beehive cluster and the moon on the 10th.

Meanwhile, at dusk, catch Saturn as it dips closer to the western horizon and pairs up with Mercury on the 24th through the 28th.

Also, Comet C/2017 O1 should still be a binocular-friendly magnitude 7 or 8 greenish object in November. Use Polaris, the North Star as a guide. Look in the East to Northeast sky in the late evening.

What’s Enceladus?

Before we tell you about Enceladus, let’s first talk about our Cassini spacecraft…

Our Cassini mission to Saturn is one of the most ambitious efforts in planetary space exploration ever mounted. Cassini is a sophisticated robotic spacecraft orbiting the ringed planet and studying the Saturnian system in detail.

Cassini completed its initial four-year mission to explore the Saturn System in June 2008. It has also completed its first mission extension in September 2010. Now, the health spacecraft is making exciting new discoveries in a second extension mission!

Enceladus

Enceladus is one of Saturn’s many moons, and is one of the brightest objects in our solar system. This moon is about as wide as Arizona, and displays at least five different types of terrain. The surface is believed to be geologically “young”, possibly less than 100 million years old.

Cassini first discovered continually-erupting fountains of icy material on Enceladus in 2005. Since then, the Saturn moon has become one of the most promising places in the solar system to search for present-day habitable environments.  

Scientists found that hydrothermal activity may be occurring on the seafloor of the moon’s underground ocean. In September, it was announced that its ocean –previously thought to only be a regional sea – was global!

Since Cassini is nearing the end of its mission, we are able to make a series of three close encounters with Enceladus, one of Saturn’s moons.

Close Encounters

On Oct. 14, Cassini performed a mid-range flyby of Enceladus, but the main event will take place on Oct. 28, when Cassini will come dizzyingly close to the icy moon. During this flyby, the spacecraft will pass a mere 30 miles above the moon’s south polar region!

This will be the deepest-ever dive through the moon’s plume of icy spray, where Cassini can collect images and valuable data about what’s going on beneath the frozen surface.

Celebrating 10 Years of Revolutionary Solar Views

Twin spacecraft give humanity unprecedented views of the entire sun at one time, traveling to the far side of our home star over the course of a 10-year mission.

These two spacecraft are called STEREO, short for Solar and Terrestrial Relations Observatory. Launched on Oct. 25, 2006, and originally slated for a two-year mission, both spacecraft sent back data for nearly eight years, and STEREO-A still sends information and images from its point of view on the far side of the sun.

STEREO watches the sun from two completely new perspectives. It also provides information invaluable for understanding the sun and its impact on Earth, other worlds, and space itself – collectively known as space weather. On Earth, space weather can trigger things like the aurora and, in extreme cases, put a strain on power systems or damage high-flying satellites.

Because the rest of our sun-watching satellites orbit near our home planet, STEREO’s twin perspectives far from Earth give us a unique opportunity to look at solar events from all sides and understand them in three dimensions.

We use data from STEREO and other missions to understand the space environment throughout the solar system. This helps operators for missions in deep space prepare for the sudden bursts of particles and magnetic field that could pose a danger to their spacecraft. 

STEREO has also helped us understand other objects in our solar system – like comets. Watching how a comet’s tail moves gives us clues about the constant stream of particles that flows out from the sun, called the solar wind.

STEREO is an essential piece of our heliophysics fleet, which includes 17 other missions. Together, these spacecraft shed new light on the sun and its interaction with space, Earth, and other worlds throughout the solar system. 

To celebrate, we’re hosting a Facebook Live event on Wednesday, Oct. 26. Join us at noon ET on the NASA Sun Science Facebook page to learn more about STEREO and ask questions.

Around the World 100,000 Times

The International Space Station is a microgravity laboratory in which an international crew of six people live and work while traveling at a speed of five miles per second (or 17,500 miles per hour), orbiting Earth every 90 minutes.

Monday, May 16, marks the International Space Station’s 100,000th orbit!

That’s more than 2,643,342,240 miles traveled! Which is also like 10 round trips to Mars, OR nearly the distance to Neptune!

The space station has been in orbit for over 17 years, and during that time, over 1,922 research investigations have been performed. More than 1,200 scientific results publications have been produced as a result. 

Important studies like the VEGGIE experiment, which is working to grow plants in microgravity, and the Twin’s Study, which is studying the impacts of microgravity on the human body, are helping us on our journey to Mars. Using this unique orbiting laboratory as a place to conduct research is helping us learn important things for future deep space missions. 

There have even been 222 different people that have visited the space station. This includes the current crew that is working and living on orbit. 

Did you know that the space station is the third brightest object in the sky? If you know when and where to look up, you can spot it on your own! Find out when and where to look up HERE.

Hello there 👋

Welcome back to Mindful Mondays! 🧘

Mondays are, famously, most people’s seventh favorite day of the week. And Mondays where everything is darker, longer, and colder than normal? Thanks, but no thanks.

But don’t panic; we’ve got something to help. It might be small, but it can make a big difference. Just ten minutes of mindfulness can go a long way, and taking some time out to sit down, slow down, and breathe can help center your thoughts and balance your mood. Sometimes, the best things in life really are free.

This year, we have teamed up with the good folks at @nasa. They want you to tune in and space out to relaxing music and ultra-high-definition visuals of the cosmos—from the surface of Mars.  

Sounds good, right? Well, it gets better. Watch more Space Out episodes on NASA+, a new no-cost, ad-free streaming service.

Why not give it a try? Just a few minutes this Monday morning can make all the difference, and we are bringing mindfulness straight to you.

Are you scared about going up into space?

I’m not scared, but I have a healthy amount of nervousness because I don’t know exactly what to expect. I have a lot of great advice, but you don’t know until you actually get there.

Hello. I'm curious what new feature the james webb brings to the table, like its ability to detect in infrared, that you are most excited about? What are you most interested to look into with this new telescope?

Why are we studying them? What’s purpose of this field for us on earth?

Dark Spot and Jovian 'Galaxy' - This enhanced-color image of a mysterious dark spot on Jupiter seems to reveal a Jovian "galaxy" of swirling storms. Juno acquired this JunoCam image on Feb. 2, 2017, at an altitude of 9,000 miles (14,500 kilometers) above the giant planet's cloud tops. This publicly selected target was simply titled "Dark Spot." In ground-based images it was difficult to tell that it is a dark storm. Citizen scientist Roman Tkachenko enhanced the color to bring out the rich detail in the storm and surrounding clouds. Just south of the dark storm is a bright, oval-shaped storm with high, bright, white clouds, reminiscent of a swirling galaxy. As a final touch, he rotated the image 90 degrees, turning the picture into a work of art. Credits: NASA/JPL-Caltech/SwRI/MSSS/Roman Tkachenko

Hunting for Organic Molecules on Mars

Did Mars once have life? To help answer that question, an international team of scientists created an incredibly powerful miniature chemistry laboratory, set to ride on the next Mars rover.

The instrument, called the Mars Organic Molecule Analyzer Mass Spectrometer (MOMA-MS), will form a key part of the ExoMars Rover, a joint mission between the European Space Agency (ESA) and Roscosmos. A mass spectrometer is crucial to send to Mars because it reveals the elements that can be found there. A Martian mass spectrometer takes a sample, typically of powdered rock, and distinguishes the different elements in the sample based on their mass.

After 8 years of designing, building, and testing, NASA scientists and engineers from NASA’s Goddard Space Flight Center said goodbye to their tiny chemistry lab and shipped it to Italy in a big pink box. Building a tiny instrument capable of conducting chemical analysis is difficult in any setting, but designing one that has to launch on a huge rocket, fly through the vacuum of space, and then operate on a planet with entirely different pressure and temperature systems? That’s herculean. And once on Mars, MOMA has a very important job to do. NASA Goddard Center Director Chris Scolese said, “This is the first intended life-detecting instrument that we have sent to Mars since Viking.”

The MOMA instrument will be capable of detecting a wide variety of organic molecules. Organic compounds are commonly associated with life, although they can be created by non-biological processes as well. Organic molecules contain carbon and hydrogen, and can include oxygen, nitrogen, and other elements.

To find these molecules on Mars, the MOMA team had to take instruments that would normally occupy a couple of workbenches in a chemistry lab and shrink them down to roughly the size of a toaster oven so they would be practical to install on a rover.

MOMA-MS, the mass spectrometer on the ExoMars rover, will build on the accomplishments from the Sample Analysis at Mars (SAM), an instrument suite on the Curiosity rover that includes a mass spectrometer. SAM collects and analyzes samples from just below the surface of Mars while ExoMars will be the first to explore deep beneath the surface, with a drill capable of taking samples from as deep as two meters (over six feet). This is important because Mars’s thin atmosphere and spotty magnetic field offer little protection from space radiation, which can gradually destroy organic molecules exposed on the surface. However, Martian sediment is an effective shield, and the team expects to find greater abundances of organic molecules in samples from beneath the surface.

On completion of the instrument, MOMA Project Scientist Will Brinckerhoff praised his colleagues, telling them, “You have had the right balance of skepticism, optimism, and ambition. Seeing this come together has made me want to do my best.”

In addition to the launch of the ESA and Roscosmos ExoMars Rover, in 2020, NASA plans to launch the Mars 2020 Rover, to search for signs of past microbial life. We are all looking forward to seeing what these two missions will find when they arrive on our neighboring planet.
