What Would These Astronauts Put In Their #NASAMoonKit?

Do you have any messages or tips for other girls who want to study and work in STEM fields?

You’ve Heard “Houston, we’ve had a problem,” But Do You Know The Mission It’s From?

It’s the 50th anniversary of the Apollo 13 mission! NASA’s “successful failure,”Apollo 13 was to be the third lunar landing attempt, but the mission was aborted mid-flight after the rupture of a service module oxygen tank. The crew never landed on the moon, but due to the dedication and ingenuity of Mission Control, made it back to Earth safely. We’ve put some of the most important numbers of the Apollo 13 mission in perspective. Check it out!

Listen to the mission in real time, HERE.

Strap in for a Tour of the Milky Way

The night sky isn’t flat. If you traveled deep into this part of the sky at the speed of the radio waves leaving this tower, here are some places you could reach.

Jupiter: Travel time – 35 minutes, 49 seconds.

The closest object in this view is the planet Jupiter, brilliant now in the evening sky…and gorgeous when seen up close by our Juno spacecraft. Distance on the night this picture was taken: 400 million miles (644 million kilometers). 

Saturn: Travel time – one hour and 15 minutes.

The next closest is Saturn, another bright “star” in this summer’s sky. On the right, one of the Cassini spacecraft’s last looks. Distance: 843 million miles (1.3 billion kilometers).

Pluto: Light-speed travel time from the radio tower – four hours, 33 minutes.

It’s not visible to the unaided eye, but Pluto is currently found roughly in this direction. Our New Horizons space mission was the first to show us what it looks like. Distance: more than 3 billion miles.

F-type star, HD 169830: Light-speed travel time from the radio tower – 123 years.

Within this patch of sky, there’s an F-type star called HD 169830. At this speed, it would take you 123 years to get there. We now know it has at least two planets (one of which is imagined here) — just two of more than 4,000 we've found…so far.

The Lagoon Nebula: Light-speed travel time from the radio tower – 4,000 years.

If you look closely, you’ll see a fuzzy patch of light and color here. If you look *really* closely, as our Hubble Space Telescope did, you’ll see the Lagoon Nebula, churning with stellar winds from newborn stars.

Black hole, Sagittarius A*: Light-speed travel time from the radio tower – 26,000 years.

In 26,000 years, after passing millions of stars, you could reach the center of our galaxy. Hidden there behind clouds of dust is a massive black hole. It’s hidden, that is, unless you use our Chandra X-ray Observatory which captured the x-ray flare seen here.

The next time you’re under a deep, dark sky, don’t forget to look up…and wonder what else might be out there.

NASA’s New Planet Hunter Reveals a Sky Full of Stars

NASA’s newest planet-hunting satellite — the Transiting Exoplanet Survey Satellite, or TESS for short — has just released its first science image using all of its cameras to capture a huge swath of the sky! TESS is NASA’s next step in the search for planets outside our solar system, called exoplanets.

This spectacular image, the first released using all four of TESS’ cameras, shows the satellite’s full field of view. It captures parts of a dozen constellations, from Capricornus (the Sea Goat) to Pictor (the Painter’s Easel) — though it might be hard to find familiar constellations among all these stars! The image even includes the Large and Small Magellanic Clouds, our galaxy’s two largest companion galaxies.

The science community calls this image “first light,” but don’t let that fool you — TESS has been seeing light since it launched in April. A first light image like this is released to show off the first science-quality image taken after a mission starts collecting science data, highlighting a spacecraft’s capabilities.

TESS has been busy since it launched from NASA’s Kennedy Space Center in Cape Canaveral, Florida. First TESS needed to get into position, which required a push from the Moon. After nearly a month in space, the satellite passed about 5,000 miles from the Moon, whose gravity gave it the boost it needed to get into a special orbit that will keep it stable and maximize its view of the sky.

During those first few weeks, we also got a sneak peek of the sky through one of TESS’s four cameras. This test image captured over 200,000 stars in just two seconds! The spacecraft was pointed toward the constellation Centaurus when it snapped this picture. The bright star Beta Centauri is visible at the lower left edge, and the edge of the Coalsack Nebula is in the right upper corner.

After settling into orbit, scientists ran a number of checks on TESS, including testing its ability to collect a set of stable images over a prolonged period of time. TESS not only proved its ability to perform this task, it also got a surprise! A comet named C/2018 N1 passed through TESS’s cameras for about 17 hours in July.

The images show a treasure trove of cosmic curiosities. There are some stars whose brightness changes over time and asteroids visible as small moving white dots. You can even see an arc of stray light from Mars, which is located outside the image, moving across the screen.

Now that TESS has settled into orbit and has been thoroughly tested, it’s digging into its main mission of finding planets around other stars. How will it spot something as tiny and faint as a planet trillions of miles away? The trick is to look at the star!

So far, most of the exoplanets we’ve found were detected by looking for tiny dips in the brightness of their host stars. These dips are caused by the planet passing between us and its star – an event called a transit. Over its first two years, TESS will stare at 200,000 of the nearest and brightest stars in the sky to look for transits to identify stars with planets.

TESS will be building on the legacy of NASA’s Kepler spacecraft, which also used transits to find exoplanets. TESS’s target stars are about 10 times closer than Kepler’s, so they’ll tend to be brighter. Because they're closer and brighter, TESS’s target stars will be ideal candidates for follow-up studies with current and future observatories.

TESS is challenging over 200,000 of our stellar neighbors to a staring contest! Who knows what new amazing planets we’ll find?

The TESS mission is led by MIT and came together with the help of many different partners. You can keep up with the latest from the TESS mission by following mission updates.

Smoke Gets In Your Eyes…and Our Instruments

Fires are some of the most dynamic and dramatic natural phenomena. They can change rapidly, burning natural landscapes and human environments alike. Fires are a natural part of many of Earth’s ecosystems, necessary to replenish soil and for healthy plant growth. But, as the planet warms, fires are becoming more intense, burning longer and hotter.

Right now, a fleet of vehicles and a team of scientists are in the field, studying how smoke from those fires affects air quality, weather and climate. The mission? It’s called FIREX-AQ. They’re working from the ground up to the sky to measure smoke, find out what’s in it, and investigate how it affects our lives.

Starting on the ground, the Langley Aerosol Research Group Experiment (LARGE) operates out of a large van. It’s one of two such vans working with the campaign, along with some other, smaller vans. It looks a little like a food truck, but instead of a kitchen, the inside is packed full of science instruments.

The team drives the van out into the wilderness to take measurements of smoke and tiny particles in the air at the ground level. This is important for a few reasons: First of all, it’s the stuff we’re breathing! It also gives us a look at smoke overnight, when the plumes tend to sink down out of the atmosphere and settle near the ground until temperatures heat back up with the Sun. The LARGE group camps out with their van full of instruments, taking continuous measurements of smoke…and not getting much sleep.

Just a little higher up, NOAA’s Twin Otter aircraft can flit down close to where the fires are actually burning, taking measurements of the smoke and getting a closer look at the fires themselves. The Twin Otters are known as “NOAA’s workhorses” because they’re easily maneuverable and can fly nice and slow to gather measurements, topping out at about 17,000 feet.

Then, sometimes flying at commercial plane height (30,000 feet) and swooping all the way down to 500 feet above the ground, NASA’s DC-8 is packed wing to wing with science instruments. The team onboard the DC-8 is looking at more than 500 different chemicals in the smoke.

The DC-8 does some fancy flying, crisscrossing over the fires in a maneuver called “the lawnmower” and sometimes spiraling down over one vertical column of air to capture smoke and particles at all different heights. Inside, the plane is full of instrument racks and tubing, capturing external air and measuring its chemical makeup. Fun fact: The front bathroom on the DC-8 is closed during science flights to make sure the instruments don’t accidentally measure anything ejected from the plane.

Finally, we make it all the way up to space. We’ve got a few different mechanisms for studying fires already mounted on satellites. Some of the satellites can see where active fires are burning, which helps scientists and first responders keep an eye on large swaths of land.

Some satellites can see smoke plumes, and help researchers track them as they move across land, blown by wind.

Other satellites help us track weather and forecast how the fires might behave. That’s important for keeping people safe, and it helps the FIREX-AQ team know where to fly and drive when they’ll get the most information. These forecasts use computer models, based on satellite observations and data about how fires and smoke behave. FIREX-AQ’s data will be fed back into these models to make them even more accurate.

We are going to the Moon!

At 1:47 a.m. EST on Nov. 16, 2022, our Orion spacecraft launched aboard the Space Launch System (SLS) rocket from historic Launch Complex 39B at NASA’s Kennedy Space Center in Florida on a path to the Moon, officially beginning the Artemis I mission.

This mission is the first integrated test of NASA’s deep space exploration systems: the Orion spacecraft, the SLS rocket, and Kennedy ground systems. This is the very first time this rocket and spacecraft have flown together, and it’s the first of many Artemis missions to the Moon. Artemis I is uncrewed, but it lays the groundwork for increasingly complex missions that will land humans on the lunar surface, including the first woman and the first person of color to do so.

With Artemis, we will build a long-term human presence on the Moon and prepare humanity for future exploration plans to Mars and beyond.

Home is Where the Astronaut Is…

The International Space Station serves as a home, office and recreation room for astronauts. They share this confined space far above the Earth with crew members from different countries and cultures for as long as six months or more. At the same time, maintaining individual well-being and crew harmony is important for the crew and mission success.

The Culture, Values and Environmental Adaptation in Space (At Home in Space) Investigation, looks at changes in perceptions about home in space and the ways a unique culture may develop aboard the station during a mission. Discover more about this study HERE.

Get Space-Crafty with Earth Science!

It’s time to get space-crafty! (Get it?) We’re getting ready to launch Landsat 9 into space this fall, and we want to know, how does Landsat inspire you?

For nearly 50 years, Landsat satellites have been collecting important data and taking beautiful images of Earth, as a partnership between NASA and the U.S. Geological Survey. Scientists and policy makers alike use this data to understand climate change, deforestation, the growth of cities, and so much more.

In celebration of the Landsat 9 launch in September, we are calling all crafters to create space-crafts inspired by your favorite Landsat image! From watercolor paintings to needlework to frosted cakes, let your creativity flow and show us how you see Landsat images.

Post a picture of your craft on Instagram, Twitter or Facebook with the hashtag #LandsatCraft. We will spotlight some on social media!

For a little inspiration, here are some #LandsatCraft examples from some of the people who work with Landsat:

“Looking through the Visible Earth Landsat gallery for inspiration, I saw the Landsat Image Mosaic of Antarctica (LIMA) and knew immediately what I had to do -- recreate it in a mosaic of my own. LIMA is a composite of more than 1,000 cloud-free Landsat 7 images of Antarctica, and when it was released in 2007 it was our first high resolution, true-color look at the icy continent.” – Kate Ramsayer, NASA Landsat Communications Coordinator

“I love embroidering satellite imagery and NASA data. For Landsat, I wanted something with lots of straight lines -- much easier to stitch! -- and crop fields like these fit the bill. It’s amazing how clearly we can see the influence of human activities in satellite imagery like this. It’s a constant reminder of the effect we have on our home planet.” – Katy Mersmann, Earth Science Social Media Lead

“We didn’t have the discipline or the organizational skills to do any of the really, really fancy images, like Lena Delta, so we chose Garden City, Kansas in 1972. We added a model of Landsat 1, too.” – Ryan Fitzgibbons, Earth Science Producer, and Charles Fitzgibbons, Age 8

"I was inspired by this Landsat image which demonstrates how we can use satellite imagery to remotely monitor cover crop performance, a sustainable farming practice that promotes soil health. Since I began working with NASA Harvest, NASA's Food Security and Agriculture Program, I've come to understand the critical importance of conservation agriculture and resilient farmlands in support of a food secure future for all, especially in the face of a changing climate." – Mary Mitkish, NASA Harvest Communications Lead

“I chose particular ingredients that represent the Landsat qualities that we celebrate:

The base spirit is gin because Landsat data is clean and precise. Vermouth represents our foreign collaborators. Using both lemon and lime juices signifies the diverse uses of the data. The ginger is for the land we study. The apple, well, because it’s American. The club soda makes it a long drink, for the long data record.” – Matthew Radcliff, NASA Landsat Producer

“Last year for the 50th Earth Day, I created this poster, inspired by our views of river deltas -- many captured by Landsat satellites -- which are particularly beautiful and evocative of water coursing through our land like a circulation system of nature. In 2000, Landsat 7 took one of my favorite images of the Lena Delta, which is the basis for this art.” – Jenny Mottar, Art Director for NASA Science

Are you feeling inspired to create yet? We’re so excited to see your #LandsatCraft projects! Follow NASA Earth on Twitter, Facebook, and Instagram to see if your art is shared!
