Welcome back to Mindful Mondays! đ§
Mondays are, famously, most peopleâs seventh favorite day of the week. And Mondays where everything is darker, longer, and colder than normal? Thanks, but no thanks.
But donât panic; weâve 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 cosmosâfrom the surface of Mars. Â
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.Â

Does an ecplispe cause any unusual effects on the Earth?
Yes, and this is one of the things weâre hoping to study more with this eclipse! If you are in totality, youâll notice a significant temperature drop. We are also expecting to see changes in the Earthâs atmosphere and ionosphere. You can help us document these changes using the GLOBE Observer app https://www.globe.gov/globe-data/data-entry/globe-observer ! There are lots of great citizen science going on during this eclipse, and weâd love to have everyone here helping out! https://eclipse2017.nasa.gov/citizen-explorers
It looks like our Hubble Space Telescope captured an image of a peaceful, cosmic butterfly unfurling its celestial wings, but the truth is vastly more violent. In the Butterfly Nebula, layers of gas are being ejected from a dying star. Medium-mass stars grow unstable as they run out of fuel, which leads them to blast tons of material out into space at speeds of over a million miles per hour!
Streams of intense ultraviolet radiation cause the cast-off material to glow, but eventually the nebula will fade and leave behind only a small stellar corpse called a white dwarf. Our middle-aged Sun can expect a similar fate once it runs out of fuel in about six billion years.
Planetary nebulas like this one arenât actually related to planets; the term was coined by astronomer William Herschel, who actually discovered the Butterfly Nebula in 1826. Through his small telescope, planetary nebulas looked like glowing, planet-like orbs. While stars that generate planetary nebulas may have once had planets orbiting them, scientists expect that the fiery death throes these stars undergo will ultimately leave any planets in their vicinity completely uninhabitable.

Not long after midnight on Dec. 7, 1972, the last crewed mission to the Moon, Apollo 17, lifted off with three astronauts: Eugene Cernan, Harrison Schmitt, and Ronald Evans.
Experience the Apollo 17 launch and follow the mission in real time.
Letâs meet the astronauts who made the final Apollo trip to the Moon, including the first scientist-astronaut.
Gene Cernan: In 1972, Apollo 17 Mission Commander Eugene A. Cernan had two space flights under his belt, Gemini 9 in June 1966, and Apollo 10 in May 1969. He was a naval aviator, electrical and aeronautical engineer and fighter pilot.
Ron Evans: Apollo 17 Command Module Pilot Ronald E. Evans was selected as a member of the 4th group of NASA astronauts in 1966. Like Cernan, he was an electrical and aeronautical engineer, and naval aviator before his assignment to the Apollo 17 crew.
Harrison (Jack) Schmitt: Lunar Module Pilot Dr. Harrison (Jack) Schmitt joined NASA as a member of the first group of scientist-astronauts in 1965. Before working for NASA, Schmitt was a geologist at the USGS Astrogeology Center. He was on the backup crew for Apollo 15 before being selected for the prime crew of Apollo 17. He became the first of the scientist-astronauts to go to space and the 12th human to walk on the Moon.
âThe Blue Marble,â one of the most reproduced images in history, was taken 50 years ago on Dec. 7, 1972 by the Apollo 17 crew as they made their way to the Moon.
NASA astronauts have an array of menu items to stay well fed and hydrated on missions. For Apollo 17, the menus allocated around 2,500 calories per day for each astronaut. They included:
Bacon Squares
Peanut Butter Sandwiches
Frankfurters
Lobster Bisque
Like anything going to space, weight and containment matter. That's why the Apollo 17 menu included plenty of soups and puddings.
On Dec. 11, 2022, the Artemis I mission will be splashing down on Earth after its 25.5-day mission. At 2:55 p.m. 50 years prior, the Apollo 17 lunar module (LM) landed on the Moon, with Commander Gene Cernan and LM Pilot Harrison Schmitt on board. Ron Evans remained in the Command and Service Module (CSM) orbiting the Moon.
Experience the landing.
One of the first tasks the Apollo 17 crew did on their first moonwalk was to plant the American flag. Thereâs no wind on the Moon, but that doesnât mean the flag has to droop. Did you know that a horizontal rod with a latch makes the flag appear to be flying in the wind? Gene Cernan carefully composed this photo to get Schmitt, the flag, and the Earth in a single shot.
So, is the flag still there? Images of the Apollo 17 landing site from the Lunar Reconnaissance Orbiter Camera show that in 2011 the flag was still standing and casting a shadow!
During Apollo 17, the Lunar Rover Vehicle (LRV), nicknamed the Moon buggy, logged the farthest distance from the Lunar Module of any Apollo mission, about 4.7 miles (7.5 km).Â
As a precaution, the LRV had a walk-back limit in the event of an issue; astronauts had to have enough resources to walk back to the lunar module if need be.
The right rear fender extension of the LRV (Moon buggy) was torn off, kicking up dust as the crew drove, reducing visibility. The crew made a resourceful repair using duct tape and maps.
For LRV fans, visiting an LRV driven on the Moon is a bit difficult since all three LRVs used on the Apollo 15, 16, and 17 missions were left on the Moon. But you can find an LRV used for training at the National Air and Space Museum in Washington. Read more about the LRV.
After the first lunar EVA, Apollo 17 astronaut Harrison Schmitt reported that he suffered from âlunar hay feverâ in reaction to the lunar dust. Unlike Earthâs dust particles which are rounded, Moon dust particles are sharp and abrasive, irritating astronaut eyes, nasal passages, and lungs.

After his return to Earth, Apollo 17 astronaut Harrison Schmitt (on the right) described his time on the Moon:
âWorking on the Moon is a lot of fun. Itâs like walking around on a giant trampoline all the time and youâre just as strong as you were here on Earth, but you donât weigh as much.â
After 12 days and 14 hours in space, the Apollo 17 astronauts splashed down in the Pacific Ocean at 2:25 p.m. EST on Dec. 19, 1972. It was the longest of all the Apollo missions, with the most photos taken. A recovery team was waiting on the USS Ticonderoga just 4 miles (6.4 km) away to pick up the astronauts, the lunar samples, and the Crew Module.
NASAâs Artemis Program has taken its first steps to sending humans back to the Moon with Artemis I, currently on its way back to Earth. The program plans to land humans, including the first women and person of color, on the Moonâs south polar region with its Artemis III mission, currently slated to launch in 2025.

Relationships can be complicated â especially if youâre a pair of stars. Sometimes you start a downward spiral you just canât get out of, eventually crash together and set off an explosion that can be seen 130 million light-years away.
For Valentineâs Day, weâre exploring the bonds between some of the universeâs peculiar pairs ⌠as well as a few of their cataclysmic endings.
When you look at a star in the night sky, you may really be viewing two or more stars dancing around each other. Scientists estimate three or four out of every five Sun-like stars in the Milky Way have at least one partner. Take our old north star Thuban, for example. Itâs a binary, or two-star, system in the constellation Draco.
Alpha Centauri, our nearest stellar neighbor, is actually a stellar triangle. Two Sun-like stars, Rigil Kentaurus and Toliman, form a pair (called Alpha Centauri AB) that orbit each other about every 80 years. Proxima Centauri is a remote red dwarf star caught in their gravitational pull even though it sits way far away from them (like over 300 times the distance between the Sun and Neptune).

Sometimes, though, a stellar couple ends its relationship in a way thatâs really disastrous for one of them. A black widow binary, for example, contains a low-mass star, called a brown dwarf, and a rapidly spinning, superdense stellar corpse called a pulsar. The pulsar generates intense radiation and particle winds that blow away the material of the other star over millions to billions of years.
In romance novels, an air of mystery is essential for any love interest, and black holes are some of the most mysterious phenomena in the universe. They also have very dramatic relationships with other objects around them!
Scientists have observed two types of black holes. Supermassive black holes are hundreds of thousands to billions of times our Sunâs mass. One of these monsters, called Sagittarius A* (the â*â is pronounced âstarâ), sits at the center of our own Milky Way. In a sense, our galaxy and its black hole are childhood sweethearts â theyâve been together for over 13 billion years! All the Milky-Way-size galaxies weâve seen so far, including our neighbor Andromeda (pictured below), have supermassive black holes at their center!
These black-hole-galaxy power couples sometimes collide with other, similar pairs â kind of like a disastrous double date! Weâve never seen one of these events happen before, but scientists are starting to model them to get an idea of what the resulting fireworks might look like.
One of the most dramatic and fleeting relationships a supermassive black hole can have is with a star that strays too close. The black holeâs gravitational pull on the unfortunate star causes it to bulge on one side and break apart into a stream of gas, which is called a tidal disruption event.
The other type of black hole you often hear about is stellar-mass black holes, which are five to tens of times the Sunâs mass. Scientists think these are formed when a massive star goes supernova. If there are two massive stars in a binary, they can leave behind a pair of black holes that are tied together by their gravity. These new black holes spiral closer and closer until they crash together and create a larger black hole. The National Science Foundationâs LIGO project has detected many of these collisions through ripples in space-time called gravitational waves.

Hereâs hoping your Valentineâs Day is more like a peacefully spiraling stellar binary and less like a tidal disruption! Learn how to have a safe relationship of your own with black holes here.

You don't necessarily need fancy equipment to watch one of the sky's most awesome shows: a solar eclipse. With just a few simple supplies, you can make a pinhole camera that allows you to view the event safely and easily. Before you get started, remember: You should never look at the Sun directly without equipment that's specifically designed for solar viewing. Do not use standard binoculars or telescopes to watch the eclipse, as the light could severely damage your eyes. Sunglasses also do NOT count as protection when attempting to look directly at the Sun. Stay safe and still enjoy the Sun's stellar show by creating your very own pinhole camera. It's easy!Â

Testing is underway at NASAâs Marshall Space Flight Center in Huntsville, Alabama, on the agencyâs new Space Launch System, the worldâs most powerful rocket. SLS and NASAâs Orion spacecraft will enable deep-space missions, beginning a new era of exploration beyond Earthâs orbit.
Engineers at Marshall have stacked four qualification articles of the upper part of SLS into a 65-foot-tall test stand using more than 3,000 bolts to hold the hardware together. Tests are currently underway to ensure the rocket hardware can withstand the pressures of launch and flight.Â
The integrated tests consists of:
1. Launch Vehicle Adapter
2. Frangible Joint Assembly
3. Interim Cryogenic Propulsion Stage
4. Orion Stage Adapter
Engineers are using 28 load pistons to push, pull and twist the rocket hardware, subjecting it to loads up to 40 percent greater than that expected during flight. More than 100 miles of cables are transmitting measurements across 1,900 data channels.
The Launch Vehicle Stage Adapter, LVSA, connects the SLS core stage and the Interim Cryogenic Propulsion Stage, ICPS. The LVSA test hardware is 26.5 feet tall, with a bottom diameter of 27.5 feet and a top diameter of 16.8 feet. The frangible joint, located between the LVSA and ICPS, is used to separate the two pieces of hardware during flight, allowing the ICPS to provide the thrust to send Orion onto its mission.
The ICPS is a liquid oxygen/liquid hydrogen-based system that will give Orion the big, in-space push needed to fly beyond the moon before it returns to Earth on the first flight of SLS in 2018. For this test series, the fuel tanks are filled with nonflammable liquid nitrogen and pressurized with gaseous nitrogen to simulate flight conditions. The nitrogen is chilled to the same temperature as the oxygen and hydrogen under launch conditions.
The Orion Stage Adapter connects the Orion spacecraft to the ICPS. It is 4.8 feet tall, with a 16.8-foot bottom diameter and 18-foot top diameter.
The first integrated flight for SLS and Orion will allow NASA to use the lunar vicinity as a proving ground to test systems farther from Earth, and demonstrate Orion can get to a stable orbit in the area of space near the moon in order to support sending humans to deep space, including the Journey to Mars.Â
For more information about the powerful SLS rocket, check out: http://nasa.gov/SLS.Â
Today we successfully tested one of our RS-25 engines, four of which will help power our Space Launch System (SLS) to deep space destinations, like Mars! This 500-second engine test concludes a summer of successful hot fire testing for flight controllers at our Stennis Space Center near Bay St. Louis, Mississippi.
The controller serves as the âbrainâ of the engine, communicating with SLS flight computers to ensure engines are performing at needed levels. The test marked another step toward the nationâs return to human deep-space exploration missions.
We launched a series of summer tests with a second flight controller unit hot fire at the end of May, then followed up with three additional tests. The flight controller tests are critical preparation for upcoming SLS flights to deep spaceâ the uncrewed Exploration Mission-1 (EM-1), which will serve as the first flight for the new rocket carrying an uncrewed Orion spacecraft, and EM-2, which will transport a crew of astronauts aboard the Orion spacecraft.Â
Each SLS rocket is powered at launch by four RS-25 engines firing simultaneously and working in conjunction with a pair of solid rocket boosters. The engines generate a combined 2 million pounds of thrust at liftoff. With the boosters, total thrust at liftoff will exceed 8 million pounds!

Today, weâre expressing gratitude for the opportunity to rove on Mars (#ThanksOppy) as we mark the completion of a successful mission that exceeded our expectations. Â
Our Opportunity Roverâs last communication with Earth was received on June 10, 2018, as a planet-wide dust storm blanketed the solar-powered rover's location on the western rim of Perseverance Valley, eventually blocking out so much sunlight that the rover could no longer charge its batteries. Although the skies over Perseverance cleared, the rover did not respond to a final communication attempt on Feb. 12, 2019.
As the roverâs mission comes to an end, here are a few things to know about its opportunity to explore the Red Planet.
Opportunity launched on July 7, 2003 and landed on Mars on Jan. 24, 2004 for a planned mission of 90 Martian days, which is equivalent to 92.4 Earth days. While we did not expect the golf-cart-sized rover to survive through a Martian winter, Opportunity defied all odds as a 90-day mission turned into 15 years!
The Opportunity caught its own silhouette in this late-afternoon image taken in March 2014 by the rover's rear hazard avoidance camera. This camera is mounted low on the rover and has a wide-angle lens.
Opportunity's achievements, including confirmation water once flowed on Mars. Opportunity was, by far, the longest-lasting lander on Mars. Besides endurance, the six-wheeled rover set a roaming record of 28 miles.
This chart illustrates comparisons among the distances driven by various wheeled vehicles on the surface of Earth's moon and Mars. Opportunity holds the off-Earth roving distance record after accruing 28.06 miles (45.16 kilometers) of driving on Mars.
Opportunity was created to be the mechanical equivalent of a geologist walking from place to place on the Red Planet. Its mast-mounted cameras are 5 feet high and provided 360-degree two-eyed, human-like views of the terrain. The robotic arm moved like a human arm with an elbow and wrist, and can place instruments directly up against rock and soil targets of interest. The mechanical "hand" of the arm holds a microscopic camera that served the same purpose as a geologist's handheld magnifying lens.
After an airbag-protected landing craft settled onto the Red Planetâs surface and opened, Opportunity rolled out to take panoramic images. These images gave scientists the information they need to select promising geological targets that tell part of the story of water in Mars' past. Since landing in 2004, Opportunity has captured more than 200,000 images. Take a look in this photo gallery.
From its perch high on a ridge, the Opportunity rover recorded this image on March 31, 2016 of a Martian dust devil twisting through the valley below. The view looks back at the rover's tracks leading up the north-facing slope of "Knudsen Ridge," which forms part of the southern edge of "Marathon Valley
Among the mission's scientific goals was to search for and characterize a wide range of rocks and soils for clues to past water activity on Mars. In its time on the Red Planet, Opportunity discovered small spheres of the mineral hematite, which typically forms in water. In addition to these spheres that a scientist nicknamed âblueberries,â the rover also found signs of liquid water flowing across the surface in the past: brightly colored veins of the mineral gypsum in rocks, for instance, which indicated water flowing through underground fractures.
The small spheres on the Martian surface in this close-up image are near Fram Crater, visited by the Opportunity rover in April 2004.
