What’s Up For March 2017?

What’s Up for March 2017?

What’s Up for March? The moon hides red star Aldebaran and crescents dazzle after dusk.

What’s Up For March 2017?

On March 4 the first quarter moon passes between Earth and the star Aldebaran, temporarily blocking our view of the star. This is called an occultation. 

What’s Up For March 2017?

The occultation begins and concludes at different times, depending on where you are when you view it.

What’s Up For March 2017?

The event should be easy to see from most of the U.S., Mexico, most of Central America, the Western Caribbean and Bermuda. 

What’s Up For March 2017?

Observers along a narrow path from Vancouver, British Columbia, to Hartford, Connecticut, will see the moon “graze” the star. The star will disappear and reappear repeatedly as hills and valleys on the moon alternately obscure and reveal it.

What’s Up For March 2017?

As seen from Earth, both Mercury and Venus have phases like our moon. That’s because they circle the sun inside Earth’s orbit. 

What’s Up For March 2017?

Planets that orbit between Earth and the sun are known as inner or inferior planets.

What’s Up For March 2017?

Inferior planets can never be at “opposition,” which is when the planet and the sun are on opposite sides of Earth.

What’s Up For March 2017?

But inferior planets can be at “conjunction,” which is when a planet, the sun and Earth are all in a straight line. 

What’s Up For March 2017?

Conjunction can happen once when the planet is on the opposite side of the sun from Earth and again when it’s on the same side of the sun as Earth. 

What’s Up For March 2017?

When a planet is on the opposite side of the sun from Earth, we say it is at “superior conjunction.” As the planet moves out from behind the sun and gets closer to Earth, we see less and less of the lit side. We see phases, similar to our moon’s phases. 

What’s Up For March 2017?

Mercury is at superior conjunction on March 6. 

What’s Up For March 2017?

A few weeks later, the planet emerges from behind the sun and we can once again observe it. By the end of March we’ll see a last-quarter Mercury.

What’s Up For March 2017?

 On April 20 Mercury reaches “inferior conjunction.”

What’s Up For March 2017?

Brilliant Venus is also racing toward its own inferior conjunction on March 25. Watch its crescent get thinner and thinner as the planet’s size appears larger and larger, because it is getting closer to Earth.

What’s Up For March 2017?

Finally, look for Jupiter to rise in the East. It will be visible all month long from late evening until dawn.

7 Things You Didn’t Know Came from NASA Technology

Every  year, we publish a round-up of 50 or so NASA innovations that can also be found  in our daily  lives here on Earth.

We call them spinoffs — technologies spun off from America’s space program — and this week the 2017 edition was published.  Here are some of our favorite things we bet you didn’t know use space technology.

image

1.Crash Test Cameras 

Parachutes are a key part of the landing system for many of our spacecraft, but before we send them into orbit — or beyond — we have to make sure that they’re going to work as designed. One important component of testing is a video that captures every millisecond as the chute opens, to see if it’s working and if not, what went wrong. 

Integrated Design Tools built a camera for us that could do just that: rugged and compact, it can film up to 1,000 frames per second and back up all that data almost as fast.  Now that same technology is being used to record crash tests, helping ensure that we’re all safer on the roads.

image

2.Archaeology 

We often use laser-imaging technology, or lidar, on missions in outer space. Thanks to lidar, snow was discovered on Mars, and the technology will soon help us collect a sample from an asteroid to bring home to Earth. 

To do all that, we’ve helped make smaller, more rugged, and more powerful lidar devices, which have proven useful here on Earth in a lot of ways, including for archaeologists. Lidar scans can strip away the trees and bushes to show the bare earth—offering clues to help find bones, fossils, and human artifacts hidden beneath the surface. 

image

3.Golf Clubs 

A screw is a screw, right? Or is it?  

When we were building the Space Shuttle, we needed a screw that wouldn’t loosen during the intense vibrations of launch. An advanced screw threading called Spiralock, invented by the Holmes Tool Company and extensively tested at Goddard Space Flight Center, was the answer.  

Now it’s being used in golf clubs, too. Cobra Puma Golf built a new driver with a spaceport door (designed to model the International Space Station observatory) that allows the final weight to be precisely calibrated by inserting a tungsten weight before the door is screwed on.  

And to ensure that spaceport door doesn’t pop off, Cobra Puma Golf turned to the high-tech threading that had served the Space Shuttle so well. 

image

4.Brain Surgery 

Neurosurgery tools need to be as precise as possible.

One important tool, bipolar forceps, uses electricity to cut and cauterize tissue. But electricity produces waste heat, and to avoid singeing healthy brain tissue, Thermacore Inc. used a technology we’ve been relying on since the early days of spaceflight: heat pipes.  The company, which built its expertise in part through work it has done for us over more than 30 years, created a mini heat pipe for bipolar forceps.  

The result means surgery is done more quickly, precisely — and most importantly, more safely.

image

5.Earthquake Protection 

The Ares 1 rocket, originally designed to launch crewed missions to the moon and ultimately Mars, had a dangerous vibration problem, and the usual solutions were way too bulky to work on a launch vehicle.  

Our engineers came up with a brand new technology that used the liquid fuel already in the rocket to get rid of the vibrations. And, it turns out, it works just as well with any liquid—and not just on rockets.  

An adapted version is already installed on a building in Brooklyn and could soon be keeping skyscrapers and bridges from being destroyed during earthquakes. 

image

6.Fertilizer 

When excess fertilizer washes away into ground water it’s called nutrient runoff, and it’s a big problem for the environment. It’s also a problem for farmers, who are paying for fertilizer the plant never uses. 

Ed Rosenthal, founder of a fertilizer company called Florikan, had an idea to fix both problems at once: coating the fertilizer in special polymers to control how quickly the nutrient dissolves in water, so the plant gets just the right amount at just the right time.  

Our researchers helped him perfect the formula, and the award-winning fertilizer is now used around the world — and in space. 

image

7. Cell Phone Cameras  

The sensor that records your selfies was originally designed for something very different: space photography.  

Eric Fossum, an engineer at NASA’s Jet Propulsion Laboratory, invented it in the 1990s, using technology called complementary metal-oxide semiconductors, or CMOS. The technology had been used for decades in computers, but Fossum was the first person to successfully adapt it for taking pictures. 

As a bonus, he was able to integrate all the other electronics a camera needs onto the same computer chip, resulting in an ultra-compact, energy-efficient, and very reliable imager. Perfect for sending to Mars or, you know, snapping a pic of your meal.

7 Things to Know about the Perseverance Mars Rover

image

We’re set to launch the Mars 2020 Perseverance rover mission from Cape Canaveral, Florida, on July 30. The rover is loaded with scientific instruments and advanced technology, making it the largest, heaviest and most sophisticated vehicle ever sent to the Red Planet.

What is Perseverance’s mission and what will it do on Mars? Here are seven things to know:

1. Perseverance draws on the NASA – and scientific – spirit of overcoming challenges

image

Not only does it have to launch during a pandemic and land on a treacherous planet, it has to carry out its science goals:

Searching for signs of past microbial life

Mapping out the planet’s geology and climate

Collecting rock and other samples for future return to Earth

Paving the way for human exploration

We chose the name Perseverance from among the 28,000 essays submitted during the "Name the Rover" contest. Because of the coronavirus pandemic, the months leading up to the launch in particular have required creative problem solving, teamwork and determination.

2. Perseverance builds on the lessons from other Mars rovers

image

In 1997, our first Mars rover – Sojourner – showed that a robot could rove on the Red Planet. Spirit and Opportunity, which both landed in 2004, found evidence that Mars once had water before becoming a frozen desert.

Curiosity found evidence that Mars’ Gale Crater was home to a lake billions of years ago and that there was an environment that may have sustained microbial life. Perseverance aims to answer the age-old question – are there any signs that life once existed on Mars?

3. Perseverance will land in a place with high potential to find signs of ancient life

image

The rover will land in Jezero Crater, a 28-mile wide basin north of the Martian equator. A space rock hit the surface long ago, creating the large hole. Between 3 and 4 billion years ago, a river flowed into a body of water in Jezero the size of Lake Tahoe.

4. Perseverance will also collect important data about Mars’ geology and climate

image

Mars orbiters have collected images and other data about Jezero Crater from about 200 miles above, but finding signs of past life will need much closer inspection. A rover like Perseverance can look for those signs that may be related to ancient life and analyze the context in which they were found to see if the origins were biological.

5. Perseverance is the first leg of a round trip to Mars

image

This is the first rover to bring a sample-gathering system to Mars that will package promising samples of rocks and other materials for future return to Earth. NASA and ESA are working on the Mars Sample Return campaign, so we can analyze the rocks and sediment with tools too large and complex to send to space.

6. Perseverance will pave the way for human exploration of the Red Planet

image

Two packages -- one that helps the rover autonomously avoid hazards during landing (TRN) and another that gathers crucial data during the trip through Mars’ atmosphere (MEDLI2) – will help future human missions land safely and with larger payloads on other worlds.

There are two instruments that will specifically help astronauts on the Red Planet. One (MEDA) will provide key information about the planet’s weather, climate and dust activity, while a technology demonstration (MOXIE) aims to extract oxygen from Mars’ mostly carbon-dioxide atmosphere.

7. You get to ride along

7 Things To Know About The Perseverance Mars Rover

Perseverance and other parts of the Mars 2020 spacecraft feature 23 cameras, which is more than any other interplanetary mission in history. Raw images from the camera are set to be released on the mission website.

There are also three silicon chips with the names of nearly 11 million people who signed up to send their names to Mars.

And you can continue to follow the mission on Twitter and Facebook.

Vision & Microgravity...Can We See the Connection?

What do nutrition and genetics have in common? They could all be linked to vision problems experienced by some astronauts. We see people going up to space with perfect vision, but need glasses when the return home to Earth.

image

Why Does This Study Matter?

We want to be able to send astronauts to Mars, but losing vision capability along the way is a BIG problem. Discovering the cause and possible treatments or preventions will help us safely send astronauts deeper into space than ever before. 

It’s Like Solving a Mystery

We already have an idea of why vision changes occur, but the real mystery remains...why do some astronauts have these issues, and other’s don’t?

Now, let’s break it down:

Nutrition is more than just what you eat. It includes how those things work inside your body. The biochemistry behind how your muscles make energy, how your brain utilizes glucose and how vitamins help with biochemical functions...it’s all part of nutrition.

Genetics also play a part in the vision changes we’re seeing in space. Data shows that there are differences in blood chemistry between astronauts that had vision issues and those that did not. We found that individuals with vision issues had different blood chemistries even before their flight to space. That means that some astronauts could be predisposed to vision issues in space.

Just in January 2016, scientists discovered this possible link between genetics, nutrition and vision changes in astronauts. It makes it clear that the vision problem is WAY more complex than we initially thought. 

image

While we still don’t know exactly what is causing the vision issues, we are able to narrow down who to study, and refine our research. This will help find the cause, and hopefully lead to treatment and prevention of these problems.

Fluid Shifts

image

The weightless environment of space also causes fluid shifts to occur in the body. This normal shift of fluids to the upper body in space causes increased inter-cranial pressure which could be reducing visual capacity in astronauts. We are currently testing how this can be counteracted by returning fluids to the lower body using a “lower body negative pressure” suit, also known as Chibis.

Benefits on Earth

Research in this area has also suggested that there may be similarities between astronaut data and individuals with a clinical syndrome affecting 10-20% of women, known as polycystic ovary syndrome. Studying this group may provide a way to better understand vision and cardiovascular system effects, which could also advance treatment and prevention for both astronauts and humans on Earth with this disease.

100 Days in Houston

A lot can happen in 100 days...

At our Johnson Space Center, located in Houston, it has been busy since July 10. Here are six things that have been going on in Houston with our astronauts, the International Space Station and our next great telescope! Take a look:

1. Our James Webb Space Telescope is Spending 100 Days in a Freezing Cold Chamber

Imagine seeing 13.5 billion light-years back in time, watching the birth of the first stars, galaxies evolve and solar systems form…our James Webb Space Telescope will do just that once it launches in 2019.

image

Webb will be the premier observatory of the next decade, studying every phase in the cosmic history of our universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems.

On July 10, the Webb telescope entered Johnson Space Center’s historic Chamber A for its final cryogenic test that lasts about 100 days behind a closed giant vault-like door. 

Why did we put Webb in this freezing cold chamber? To ensure it can withstand the harsh environment it will experience in space.

image

The telescope has been in a space-like environment in the chamber, tested at cryogenic temperatures. In space, the telescope must operate at extremely cold temperatures so that it can detect infrared light – heat radiation -- from faint, distant objects. 

image

To keep the telescope cold while in space, Webb has a sunshield the size of a tennis court, which blocks sunlight (as well as reflected light from the Earth and Moon). This means that the sun-facing side of the observatory is incredibly hot while the telescope-side remains at sub-freezing temperatures.

2. Our 12 new astronaut candidates reported to Houston to start training

image

Our newest class of astronaut candidates, which were announced on June 7, reported for training on August 13. These candidates will train for two years on International Space Station systems, space vehicles and Russian language, among many other skills, before being flight-ready. 

3. Our Mission Control Center operated for 2,400 hours

image

While astronauts are in space, Mission Control operates around the clock making sure the crew is safe and the International Space Station is functioning properly. This means workers in Mission Control work in three shifts, 7 a.m. – 4 p.m., 3 p.m. – midnight and 11 p.m. – 8 a.m. This includes holidays and weekends. Day or night, Mission Control is up and running.

4. Key Teams at Johnson Space Center Continued Critical Operations During Hurricane Harvey

image

Although Johnson Space Center closed during Hurricane Harvey, key team members and critical personnel stayed onsite to ensure crucial operations would continue. Mission Control remained in operation throughout this period, as well as all backup systems required to maintain the James Webb Space Telescope, which is at Johnson for testing, were checked prior to the arrival of the storm, and were ready for use if necessary.

5. Crews on the International Space Station conducted hundreds of science experiments.

image

Mission Control at Johnson Space Center supported astronauts on board the International Space Station as they worked their typical schedule in the microgravity environment. Crew members work about 10 hours a day conducting science research that benefits life on Earth as well as prepares us for travel deeper into space. 

image

The space station team in Houston supported a rigorous schedule of launches of cargo that included supplies and science materials for the crew living and working in the orbiting laboratory, launched there by our commercial partners. 

6. Two new crews blasted off to space and a record breaking astronaut returned from a stay on space station

image

Houston is home to the Astronaut Corps, some of whom end up going out-of-this-world. On July 28, NASA Astronaut Randy Bresnik launched to the International Space Station alongside Italian astronaut Paolo Naspoli and Russian cosmonaut Sergey Ryazanskiy. Joining them at the International Space Station were NASA Astronauts Joe Acaba and Mark Vande Hei who launched September 12 with Russian cosmonaut Alexander Misurkin.

image

When NASA Astronaut Peggy Whitson landed with crewmates Jack Fischer of NASA and Fyoder Yurchikhin of Roscosmos, she broke the record for the most cumulative time in space by a U.S. astronaut. She landed with over 650 days of cumulative flight time and more than 53 hours of spacewalk time. Upon her return, the Human Research Program in Houston studies her health and how the human body adapted to her time in space.

Counting Down to the Solar Eclipse on August 21

On Aug. 21, 2017, everyone in North America will have the chance to see a solar eclipse if skies are clear. We’re giving you a preview of what you’ll see, how to watch and why scientists are particularly excited for this eclipse.

image

On Aug. 21, within a narrow band stretching from Oregon to South Carolina – called the path of totality – the Moon will completely obscure the Sun, giving people on the ground a view of the total solar eclipse. Outside this path – throughout North America, and even in parts of South America – the Moon will block only a portion of the Sun’s face, creating a partial solar eclipse.

image

Image credit: T. Ruen

Eclipses happen when the Moon, Sun and Earth line up just right, allowing the Moon to cast its shadow on Earth. Because the Moon’s orbit is tilted with respect to the Sun-Earth plane, its shadow usually passes above or below Earth. But when they all line up and that shadow falls on Earth, we get a solar eclipse.

image

How to Watch the Eclipse Safely  

It’s never safe to look directly at the un-eclipsed or partially eclipsed Sun – so you’ll need special solar viewing glasses or an indirect viewing method, like pinhole projection, to watch at the eclipse.

image

If you’re using solar viewing glasses or a handheld solar filter, there are a few important safety tips to keep in mind:

Check a few key characteristics to make sure that you have proper solar filters – sunglasses (even very dark ones) or homemade filters are NOT safe  

Double-check that your solar filter is not scratched or damaged before you use it

Always put your solar filter over your eyes before looking up at the Sun, and look away from the Sun before removing it 

Do NOT use your solar filter while looking through telescopes, binoculars, or any other optical device, such as a camera viewfinder – the concentrated solar rays will damage the filter and enter your eyes, causing serious injury

Get all the details on safety at eclipse2017.nasa.gov/safety.

No solar viewing glasses? Pinhole projection is an easy and safe way to watch the eclipse. You can create a pinhole projector from a box, or simply use any object with tiny holes – like a colander or a piece of cardstock with a hole – to project an image of the Sun onto the ground or a piece of paper.

image

If you are in the path of totality, there will come a time when the Moon completely obscures the Sun’s bright face. This is called totality, and it is only during this phase – which may last only a few seconds, depending on your location – that it is safe to look directly at the eclipse.

Wherever you are, you can tune into nasa.gov/eclipselive throughout the day on Aug. 21 to hear from our experts and see the eclipse like never before – including views from our spacecraft, aircraft, and more than 50 high-altitude balloons.

A Unique Chance for Scientists

Total solar eclipses provide a unique opportunity to study the Sun and Earth. During a total eclipse, the lower parts of the Sun's atmosphere, or corona, can be seen in a way that cannot completely be replicated by current human-made instruments.

The lower part of the corona is key to understanding many processes on the Sun, including why the Sun’s atmosphere is so much hotter than its surface and the origins of the Sun’s constant stream of solar material and radiation – which can cause changes in the nature of space and impact spacecraft, communications systems, and orbiting astronauts.

image

For those in the path of totality, the few moments of the total solar eclipse will reveal the Sun’s atmosphere, the corona. 

Total solar eclipses are also a chance to study Earth under uncommon conditions: In contrast to the global change in light that occurs every day at dusk and dawn, a solar eclipse changes illumination of Earth and its atmosphere only under a comparatively small region of the Moon’s shadow. This localized blocking of solar energy is useful in evaluating our understanding of the Sun’s effects – temperature, for example – on our atmosphere. Of particular interest is the impact on Earth’s upper atmosphere, where solar illumination is primarily responsible for the generation of a layer of charged particles called the ionosphere.

image

We’re also inviting eclipse viewers around the country to become citizen scientists and participate in a nationwide science experiment by collecting cloud and air temperature data and reporting it via the GLOBE Observer smartphone app.

Athletes Go for the Gold with NASA Spinoffs

NASA technology tends to find its way into the sporting world more often than you’d expect. Fitness is important to the space program because astronauts must undergo the extreme g-forces of getting into space and endure the long-term effects of weightlessness on the human body. The agency’s engineering expertise also means that items like shoes and swimsuits can be improved with NASA know-how.

As the 2024 Olympics are in full swing in Paris, here are some of the many NASA-derived technologies that have helped competitive athletes train for the games and made sure they’re properly equipped to win.

The LZR Racer reduces skin friction drag by covering more skin than traditional swimsuits. Multiple pieces of the water-resistant and extremely lightweight LZR Pulse fabric connect at ultrasonically welded seams and incorporate extremely low-profile zippers to keep viscous drag to a minimum.

Swimsuits That Don’t Drag

When the swimsuit manufacturer Speedo wanted its LZR Racer suit to have as little drag as possible, the company turned to the experts at Langley Research Center to test its materials and design. The end result was that the new suit reduced drag by 24 percent compared to the prior generation of Speedo racing suit and broke 13 world records in 2008. While the original LZR Racer is no longer used in competition due to the advantage it gave wearers, its legacy lives on in derivatives still produced to this day.

Trilion Quality Systems worked with NASA’s Glenn Research Center to adapt existing stereo photogrammetry software to work with high-speed cameras. Now the company sells the package widely, and it is used to analyze stress and strain in everything from knee implants to running shoes and more.

High-Speed Cameras for High-Speed Shoes

After space shuttle Columbia, investigators needed to see how materials reacted during recreation tests with high-speed cameras, which involved working with industry to create a system that could analyze footage filmed at 30,000 frames per second. Engineers at Adidas used this system to analyze the behavior of Olympic marathoners' feet as they hit the ground and adjusted the design of the company’s high-performance footwear based on these observations.

Martial artist Barry French holds an Impax Body Shield while former European middle-weight kickboxing champion Daryl Tyler delivers an explosive jump side kick; the force of the impact is registered precisely and shown on the display panel of the electronic box French is wearing on his belt.

One-Thousandth-of-an-Inch Punch

In the 1980s, Olympic martial artists needed a way to measure the impact of their strikes to improve training for competition. Impulse Technology reached out to Glenn Research Center to create the Impax sensor, an ultra-thin film sensor which creates a small amount of voltage when struck. The more force applied, the more voltage it generates, enabling a computerized display to show how powerful a punch or kick was.

Astronaut Sunita Williams poses while using the Interim Resistive Exercise Device on the ISS. The cylinders at the base of each side house the SpiraFlex FlexPacks that inventor Paul Francis honed under NASA contracts. They would go on to power the Bowflex Revolution and other commercial exercise equipment.

Weight Training Without the Weight

Astronauts spending long periods of time in space needed a way to maintain muscle mass without the effect of gravity, but lifting free weights doesn’t work when you’re practically weightless. An exercise machine that uses elastic resistance to provide the same benefits as weightlifting went to the space station in the year 2000. That resistance technology was commercialized into the Bowflex Revolution home exercise equipment shortly afterwards.

Solar System: Things to Know This Week

Celebrate with us as our Opportunity rover turns 13, view art from our fans and more!

1. All Grown Up

After exceeding her 90-day mission and design parameters many times over, our plucky little rover Opportunity turns 13 years old on the Red Planet. She’s officially a teenager!

2. People’s Space

image

The public contributes so much wonderful art that we decided to make a place to share it. Enjoy!

3. Ready for a Close Up

Solar System: Things To Know This Week

Our Juno spacecraft recently got a closer look at Jupiter’s Little Red Spot. The craft’s JunoCam imager snapped this shot of Jupiter's northern latitudes on December 2016, as the spacecraft performed a close flyby of the gas giant. The spacecraft was at an altitude of 10,300 miles above Jupiter's cloud tops.

4. A New Test for Life on Other Planets 

image

A simple chemistry method could vastly enhance how scientists search for signs of life on other planets. The test uses a liquid-based technique known as capillary electrophoresis to separate a mixture of organic molecules into its components. It was designed specifically to analyze for amino acids, the structural building blocks of all life on Earth.

5. Blurring the Line Between Asteroid and Comet  

image

Our NEOWISE mission recently discovered some celestial objects traveling through our neighborhood, including one on the blurry line between asteroid and comet. An object called 2016 WF9 was detected by the NEOWISE project in November 2016 and it's in an orbit that takes it on a scenic tour of our solar system. A different object, discovered by NEOWISE a month earlier, is more clearly a comet, releasing dust as it nears the sun.

Discover the full list of 10 things to know about our solar system this week HERE.
