The Perseids are at their peak this week!

The Perseid meteor shower, one of the biggest meteor showers of the year, will be at its brightest early in the morning on Wednesday, August 12. Read on for some tips on how to watch the night sky this week – and to find out: what exactly are the Perseids, anyway?

Your best chance to spot the Perseids will be between 2 AM and dawn (local time) the morning of August 12. Find a dark spot, avoid bright lights (yes, that includes your phone) and get acclimated to the night sky.

Your eyes should be at peak viewing capacity after about 30 minutes; though the Moon may block out some of the dimmer meteors, you should still be able to see up to 15-20 an hour. If you’re not an early bird, you can try and take a look soon after sunset (around 9 PM) on the 11th, though you may not see as many Perseids then.

If it’s too cloudy, or too bright, to go skywatching where you are, you can try again Wednesday or Thursday night – or just stay indoors and watch the Perseids online!

Our Meteor Watch program will be livestreaming the Perseids from Huntsville, Alabama on Facebook (weather permitting), [link to come] starting around 9 p.m. EDT on August 11 and continuing through sunrise.

So… why are they called the Perseids?

Because all of a meteor shower’s meteors have similar orbits, they appear to come from the same place in the sky – a point called the radiant. 

The radiant for the Perseids, as you might guess from the name, is in the constellation Perseus, found near Aries and Taurus in the night sky.

But they’re not actually coming from Perseus, right?

Right! The Perseids are actually fragments of the comet Swift-Tuttle, which orbits within our solar system.

The Path to High Adventure Begins With Scouting!

Leadership, service, being prepared and doing your best – these qualities are exemplified by our astronauts, but are also shared by the Girl Scouts! Our astronaut corps has many scout alumnae, and over the years they’ve been breaking barriers and making names for themselves at NASA.

Today marks the 108th birthday of Girl Scouts in the United States, which has been inspiring generations of girls through leadership and STEM (science, technology, engineering and mathematics) activities to empower the explorers of today and tomorrow. To celebrate, we’re highlighting some of our Girl Scout alumnae over the years!

NASA astronaut and Girl Scout alumna Sunita Williams, who served as an International Space Station commander and spent 322 days in space during two spaceflight expeditions.

Former Scouts have served as crew members on numerous spaceflight missions.

From left: Susan Helms, the first female International Space Station crew member; Eileen Collins, the first woman to pilot and command a space shuttle; and Dr. Kathy Sullivan, the first American woman to perform a spacewalk.

Former Girl Scouts flew on more than one-third of the space shuttle missions and were pioneering forces as women began making their mark on human spaceflight. The first female crew member to serve on the International Space Station, the first to pilot and command a space shuttle and the first American woman to spacewalk were all Scout alumnae. 

They continue to break records, such as the first three all-woman spacewalks… 

Girl Scout alumnae and NASA astronauts Christina Koch and Jessica Meir made history when they conducted the first ever all-woman spacewalk on Oct.18, 2019. They went on to complete two more spacewalks, successfully completing their task of upgrading the space station’s battery charge/discharge unit. Christina and Jessica’s historic spacewalk was a testament to the growing number of women (and Girl Scouts) joining our astronaut corps; it is a milestone worth celebrating as we look forward to putting the first woman on the Moon with our Artemis Program! 

….and the longest spaceflight ever by a woman!

NASA astronaut Christina Koch smiles for a selfie while completing tasks during a spacewalk outside the International Space Station.

Koch went on to seal her name in the record books by surpassing Peggy Whitson’s record for the longest single spaceflight in history by a woman!

Understanding how the human body adjusts to things like weightlessness, radiation and bone-density loss is crucial as we look forward to embarking on long-duration spaceflights to the Moon and Mars. Thanks to former astronaut Scott Kelly’s Year in Space mission, we’ve been able to observe these changes on a biological male. Now, thanks to Christina’s mission, we are able to observe these changes on a biological female. 

Girl Scout alumnae will also help lead human exploration farther than ever before as members of our Artemis generation!

On January 10, 2020 we welcomed 11 new astronauts to our ranks – including three Girl Scout alumnae! As part of the first-ever class of astronauts under our Artemis lunar exploration program, Kayla Barron, Jessica Watkins and Loral O’Hara are now qualified for assignments including long-duration missions to the International Space Station, the Moon and Mars.

They took a moment after graduation to share inspiration and insight for current and future Scouts!

Q: A question from the Girl Scouts: What inspires you?

A: “Being a part of an awesome team has always been what inspires me. Whether it’s your Girl Scout troop, a sports team, your class – I think for me always the people around me who push me to succeed and support me when I make mistakes and help me become my best self is what inspires me to show up and do my best.” - NASA astronaut Kayla Barron 

Q: How has being a Girl Scout helped you in becoming an astronaut?

A: “Being in the Girl Scouts when I was younger was really cool because, well, first it was just a group of my friends who got to do a lot of different things together. But it really gave us the opportunity to be exposed to a lot of different areas. Like we’d get to go camping. We’d get to ride horses and learn all of these different skills, and so that variety of skill set I think is very applicable to being an astronaut.” - NASA astronaut Loral O’Hara 

Q: What would your advice be for the next generation of Girl Scout astronauts?

A: “My advice would be to find something that you’re passionate about. Ideally something in the STEM fields: Science, Technology, Engineering or Mathematics, and to pursue that thing that you’re interested in. Pursue that passion, whatever it is. And don’t give up on your dreams, and continue to follow them until you arrive where you want to be.” - NASA astronaut Jessica Watkins 

To all the Girl Scouts out there, keep reaching for the stars because the sky is no longer the limit! 

Astronaut applications are OPEN until March 31 for the next class of Artemis generation astronauts who will embark on missions to the International Space Station, the Moon and Mars. If you’re interested in applying to #BeAnAstronaut or just want to learn more, click HERE.

Our Space Launch System Rocket’s “Green Run” Engine Testing By the Numbers

We continue to make progress toward the first launch of our Space Launch System (SLS) rocket for the Artemis I mission around the Moon. Engineers at NASA’s Stennis Space Center near Bay St. Louis, Mississippi are preparing for the last two tests of the eight-part SLS core stage Green Run test series.

The test campaign is one of the final milestones before our SLS rocket launches America’s Orion spacecraft to the Moon with the Artemis program. The SLS Green Run test campaign is a series of eight different tests designed to bring the  entire rocket stage to life for the first time.

As our engineers and technicians prepare for the wet dress rehearsal and the SLS Green Run hot fire, here are some numbers to keep in mind:

212 Feet

The SLS rocket’s core stage is the largest rocket stage we have ever produced. From top to bottom of its four RS-25 engines, the rocket stage measures 212 feet.

35 Stories

For each of the Green Run tests, the SLS core stage is installed in the historic B-2 Test Stand at Stennis. The test stand was updated to accommodate the SLS rocket stage and is 35 stories tall – or almost 350 feet!

4 RS-25 Engines

All four RS-25 engines will operate simultaneously during the final Green Run Hot Fire. Fueled by the two propellant tanks, the cluster of engines will gimbal, or pivot, and fire for up to eight minutes just as if it were an actual Artemis launch to the Moon.

18 Miles

Our brawny SLS core stage is outfitted with three flight computers and special avionics systems that act as the “brains” of the rocket. It has 18 miles of cabling and more than 500 sensors and systems to help feed fuel and direct the four RS-25 engines.

773,000 Gallons

The stage has two huge propellant tanks that collectively hold 733,000 gallons of super-cooled liquid hydrogen and liquid oxygen. The stage weighs more than 2.3 million pounds when its fully fueled.

114 Tanker Trucks

It’ll take 114 trucks – 54 trucks carrying liquid hydrogen and 60 trucks carrying liquid oxygen – to provide fuel to the SLS core stage.

6 Propellant Barges

A series of barges will deliver the propellant from the trucks to the rocket stage installed in the test stand. Altogether, six propellant barges will send fuel through a special feed system and lines. The propellant initially will be used to chill the feed system and lines to the correct cryogenic temperature. The propellant then will flow from the barges to the B-2 Test Stand and on into the stage’s tanks.

100 Terabytes

All eight of the Green Run tests and check outs will produce more than 100 terabytes of collected data that engineers will use to certify the core stage design and help verify the stage is ready for launch.

For comparison, just one terabyte is the equivalent to 500 hours of movies, 200,000 five-minute songs, or 310,000 pictures!

32,500 holes

The B-2 Test Stand has a flame deflector that will direct the fire produced from the rocket’s engines away from the stage. Nearly 33,000 tiny, handmade holes dot the flame deflector. Why? All those minuscule holes play a huge role by directing constant streams of pressurized water to cool the hot engine exhaust.

One Epic First

When NASA conducts the SLS Green Run Hot Fire test at Stennis, it’ll be the first time that the SLS core stage operates just as it would on the launch pad. This test is just a preview of what’s to come for Artemis I!

The Space Launch System is the only rocket that can send NASA astronauts aboard NASA’s Orion spacecraft and supplies to the Moon in a single mission. The SLS core stage is a key part of the rocket that will send the first woman and the next man to the Moon through NASA’s Artemis program.

Throwback Thursday: Apollo 11 FAQ Edition

With the help of the NASA History Office, we’ve identified some of the most frequently asked questions surrounding the first time humans walked on the surface of another world. Read on and click here to check out our previous Apollo FAQs. 

How many moon rocks did the Apollo crews bring back? What did we learn?

The six crews that landed on the Moon brought back 842 pounds (382 kilograms) of rocks, sand and dust from the lunar surface. Each time, they were transferred to Johnson Space Center’s Lunar Receiving Laboratory, a building that also housed the astronauts during their three weeks of quarantine. Today the building now houses other science divisions, but the lunar samples are preserved in the Lunar Sample Receiving Laboratory.

Built in 1979, the laboratory is the chief repository of the Apollo samples.

From these pieces of the Moon we learned that its chemical makeup is similar to that of Earth’s, with some differences. Studying the samples has yielded clues to the origins of the solar system. In March of 2019, we announced that three cases of pristine Moon samples will be unsealed for the first time in 50 years so that we can take advantage of the improved technology that exists today! 

Did you know you might not have to travel far to see a piece of the Moon up close? Visit our Find a Moon Rock page to find out where you can visit a piece of the Moon.

What did Apollo astronauts eat on their way to the Moon?

Astronaut food has come a long way since the days of Project Mercury, our first human spaceflight program that ran from 1958-1963. Back then, astronauts “enjoyed” food in cube form or squeezed out of tubes. Early astronaut food menus were designed less for flavor and more for nutritional value, but that eventually shifted as technology evolved. Astronauts today can enjoy whole foods like apples, pizza and even tacos. 

Apollo crews were the first to have hot water, making it easier to rehydrate their foods and improve its taste. They were also the first to use a “spoon bowl,” a plastic container that was somewhat like eating out of a Ziploc bag with a spoon. Here’s an example of a day’s menu for a voyage to the Moon:

Breakfast: bacon squares, strawberry cubes and an orange drink.

Lunch: beef and potatoes, applesauce and a brownie.

Dinner: salmon salad, chicken and rice, sugar cookie cubes and a pineapple grapefruit drink.

What did Michael Collins do while he orbited the Moon, alone in the Command Module?

As Neil Armstrong and Buzz Aldrin worked on the lunar surface, Command Module pilot Michael Collins orbited the Moon, alone, for the next 21.5 hours. On board he ran systems checks, made surface observations and communicated with Mission Control when there wasn’t a communications blackout. Blackouts happened every time Collins went behind the Moon. In 2009, Collins wrote this in response to a flurry of media questions about the 40th anniversary of the mission:

Q. Circling the lonely Moon by yourself, the loneliest person in the universe, weren’t you lonely? A. No. Far from feeling lonely or abandoned, I feel very much a part of what is taking place on the lunar surface. I know that I would be a liar or a fool if I said that I have the best of the three Apollo 11 seats, but I can say with truth and equanimity that I am perfectly satisfied with the one I have. This venture has been structured for three men, and I consider my third to be as necessary as either of the other two.”

What will Artemis astronauts bring back when they land on the Moon?

Artemis missions to the Moon will mark humanity’s first permanent presence on another world. The first woman and the next man to explore the lunar surface will land where nobody has ever attempted to land before – on the Moon’s south pole where there are billions of tons of water ice that can be used for oxygen and fuel. We don’t know yet what astronauts will bring back from this unexplored territory, but we do know that they will return with hope and inspiration for the next generation of explorers: the Artemis generation.

The Rover Doctor is in: The Anatomy of a NASA Human Exploration Rover Challenge Rover

Exploration and inspiration collide head-on in our Human Exploration Rover Challenge held near Marshall Space Flight Center in Huntsville, Alabama, each April. The annual competition challenges student teams from around the world to design, build and drive a human-powered rover over a punishing half-mile course with tasks and obstacles similar to what our astronauts will likely have on missions to the Moon, Mars and beyond.

The anatomy of the rover is crucial to success. Take a look at a few of the vital systems your rover will need to survive the challenge!

The Chassis

A rover’s chassis is its skeleton and serves as the framework that all of the other rover systems attach to. The design of that skeleton incorporates many factors: How will your steering and braking work? Will your drivers sit beside each other, front-to-back or will they be offset? How high should they sit? How many wheels will your rover have? All of those decisions dictate the design of your rover’s chassis.

Wheels

Speaking of wheels, what will yours look like? The Rover Challenge course features slick surfaces, soft dunes, rocky craters and steep hills – meaning your custom-designed wheels must be capable of handling diverse landscapes, just as they would on the Moon and Mars. Carefully cut wood and cardboard, hammer-formed metal and even 3-D printed polymers have all traversed the course in past competitions.

Drivetrain

You’ve got your chassis design. Your wheels are good to go. Now you have to have a system to transfer the energy from your drivers to the wheels – the drivetrain. A good drivetrain will help ensure your rover crosses the finish line under the 8-minute time limit. Teams are encouraged to innovate and think outside the traditional bike chain-based systems that are often used and often fail. Exploration of the Moon and Mars will require new, robust designs to explore their surfaces. New ratchet systems and geared drivetrains explored the Rover Challenge course in 2019.

Colors and Gear

Every good rover needs a cool look. Whether you paint it your school colors, fly your country’s flag or decorate it to support those fighting cancer (Lima High School, above, was inspired by those fighting cancer), your rover and your uniform help tell your story to all those watching and cheering you on. Have fun with it!

Are you ready to conquer the Rover Challenge course? Join us in Huntsville this spring! Rover Challenge registration is open until January 16, 2020 for teams based in the United States.

If building rovers isn’t your space jam, we have other Artemis Challenges that allow you to be a part of the NASA team – check them out here.

Want to learn about our Artemis program that will land the first woman and next man on the Moon by 2024? Go here to read about how NASA, academia and industry and international partners will use innovative technologies to explore more of the lunar surface than ever before. Through collaborations with our commercial, international and academic partners, we will establish sustainable lunar exploration by 2028, using what we learn to take astronauts to Mars. 

The students competing in our Human Exploration Rover Challenge are paramount to that exploration and will play a vital role in helping NASA and all of humanity explore space like we’ve never done before!
