Hi, I'm A Curious Malaysian 😁 Can You Explain To Us About Your Career And How Do One Get To The Point

Space toilet, Radishes, and a Spacewalk in Virtual Reality

A rocket is launching to the International Space Station next week, carrying tons of science and supplies to the orbiting laboratory. It’s Northrop Grumman’s 14th (NG-14) commercial resupply cargo mission, and includes plant research, a new space toilet, and a special virtual reality camera designed to immerse you in a spacewalk. Let’s take a closer look at what’s on board, and how you can ask some of the scientists anything.

A new way to “boldly go” in space  

A new space toilet is heading to the space station. It’s smaller than the current toilets aboard the station, and includes a 3D printed titanium cover for its dual fan separator. These are just some of the upgrades that make it better suited for our deep space exploration missions. Engineers also gathered feedback from astronauts and set out to design more comfortable attachments that would make “boldly going” in space a more enjoyable experience. The toilet is being tested on the space station, and will also be used on a future Artemis mission. The new design will allow us to increase how much water we recover for use, because yep … yesterday’s coffee becomes tomorrow’s drinking water. See below for an opportunity to speak with the folks who made the new space toilet happen.  

Space plants are rad(ish)!  

Astronauts traveling to the Moon and Mars will need to grow food to supplement their diets. The latest in plant studies aboard the space station hopes to pack a crunch in that research. We’ll be growing radishes in a special plant chamber, and learning how light, water, atmosphere, and soil conditions affect the bulbous vegetables. Radishes are nutritious, grow quickly (roughly four weeks from sowing to harvest), and are genetically similar to Arabidopsis, a plant frequently studied in microgravity. What we learn could help optimize growth of the plants in space as well as provide an assessment of their nutrition and taste. See below for an opportunity to ask anything of the scientist and engineer behind this new crop.  

Immerse yourself in a spacewalk  

If going to space is on your bucket list, you might be closer than you think to checking that box. Felix & Paul Studios is creating an immersive 360 virtual reality film of a spacewalk that will put you right next to the astronauts as they go about their work on the outside of the space station … at 17,500 miles per hour. The new camera, specially designed to withstand the incredibly harsh environment of space, will be mounted on the station’s robotic arm so it can be maneuvered around the outside of the space station. Félix Lajeunesse and Paul Raphaël are the co-founders of the immersive entertainment studio, and have been producing a film aboard the space station – from Earth – for more than a year already. See below for a chance to ask them anything about what filming in space takes.  

You can join in the NG-14 Reddit Ask Me Anything on Friday, Sept. 25 to ask anything of these folks and their projects. Here’s the schedule:  

Space toilet (a.k.a the Universal Waste Management System): Melissa McKinley with NASA’s Advanced Exploration Systems and Jim Fuller of Collins Aerospace, and program manager for UWMS at 12 p.m. EDT at https://www.reddit.com/r/space.

Radishes in space (a.k.a. Plant Habitat-02): Dr. Karl Hasenstein is the scientist behind the Plant Habitat-02, and Dave Reed knows the ins and outs of the Advanced Plant Habitat of the space station. Their Reddit AMA begins at 3 p.m. EDT at https://www.reddit.com/r/gardening.

Virtual reality spacewalk camera: Félix Lajeunesse and Paul Raphaël co-founders and creative directors of Felix & Paul Studios will be taking questions at 5 p.m. EDT on https://www.reddit.com/r/filmmakers.

These are just a few of the payloads launching aboard the NG-14 Cygnus cargo vehicle to the space station next week. Read about the cancer research, and new commercial products also heading to space and watch the video above to learn more. Launch is targeted for Tuesday, Sept. 29, with a five-minute launch window opening at approximately 10:26 p.m. EDT. Live coverage begins on NASA TV at 10 p.m. EDT.

Solar System: Things to Know This Week

Like sailors of old, the Cassini mission team fondly thinks of the spacecraft as "she."  On April 22, she begins her Grand Finale, a spectacular end game—22 daring dives between the planet's atmosphere and innermost rings. Here are 10 things to know about her Grand Finale.

1. She's Broadcasting Live This Week

On Tuesday, April 4 at 3 p.m. EDT  (noon PDT), At Jet Propulsion Laboratory, the Cassini team host a news briefing to discuss the mission's Grand Finale.

Tune in Tuesday: youtube.com/nasajpl/live

2. She's Powered in Part By ... Titan

Cassini left Earth with less than 1/30th of the propellant needed to power all her adventures at Saturn. The navigation team used the gravity of Saturn's giant moon Titan to change course and extend the spacecraft's exploration of Saturn. Titan also provides the gravity assist to push Cassini into its final orbits.

More on Cassini's navigation: saturn.jpl.nasa.gov/mission/spacecraft/navigation/

3. She's a Robot

Cassini is an orbiter that was named for 18th century astronomer Giovanni Domenico Cassini. She was designed to be captured by Saturn's gravity and then explore it in detail with a suite of 12 powerful science instruments.

More on the Spacecraft: saturn.jpl.nasa.gov/mission/spacecraft/cassini-orbiter/

4. She Brought a Friend to Saturn

Cassini carried the European Space Agency's Huygens Probe, which in 2005 descended through Titan's thick, perpetual clouds and made the most distant landing to date in our solar system.

More on Huygens: saturn.jpl.nasa.gov/mission/spacecraft/huygens-probe/

5. She's a Great Photographer

Your mobile phone likely captures dozens of megapixels in images. Cassini, using 1990s technology closer to one megapixel cameras, has returned some of the most stunning images in the history of solar system exploration.

Cassini Hall of Fame Images: go.nasa.gov/2oec6H2 More on Cassini's Cameras: saturn.jpl.nasa.gov/imaging-science-subsystem/

6. She's an Inspiration

Those great images have inspired artist's and amateur image processors to create truly fantastic imagery inspired by the beauty of Saturn. Feeling inspired? There's still time to share your Cassini-inspired art with us.

Cassini Inspires Campaign: saturn.jpl.nasa.gov/mission/cassiniinspires/

7. She's Got a Long History

Two decades is a long time to live in the harsh environment of outer space (respect to the fast-approaching 40-year-old twin Voyager spacecraft). Launched in 1997, Cassini logged a lot of milestones over the years.

Explore the Cassini Timeline: saturn.jpl.nasa.gov/the-journey/timeline/

8. She Keeps a Diary

And, you can read it. Week after week going back to 1997, Cassini's adventures, discoveries and status have been chronicled in the mission's weekly significant events report.

Read It: https://saturn.jpl.nasa.gov/news/?topic=121

9. She's Got a Fancy New App

Cassini was the prototype for NASA's Eyes on the Solar System 3-D visualization software, so it's fitting the latest Cassini module in the free, downloadable software is the most detailed, elaborate visualization of any mission to date.

Solar System: Things to Know This Week

Our solar system is huge, so let us break it down for you. Here are a few things to know this week:

1. We’re Going In

To be honest, Jupiter is kind of a monster. Not only is it the biggest planet in the solar system, but it also wields the most dangerous radiation and other powerful forces. Despite the risks, our Juno probe is going in close, because Jupiter also holds precious clues to how the planets formed, including our own. Arrival date: July 4. Watch the Juno mission trailer video HERE.

2. Moon Maps

The moon is beautiful in the sky, and also up close—sometimes even in the maps that scientists use to study its surface. Here are some evocative maps that lunar geologists have drawn up to chart the landscapes in the moon’s dramatic Tycho Crater. Take a look HERE.

3. That’s No Moon…Sort Of

The full moon we’ll see this week is not Earth’s only companion in space. Astronomers have discovered a small asteroid in an orbit around the sun that keeps it near the Earth, where it will remain for centuries. But it’s not exactly a second moon, either.

4. Power Blast

Venus has an “electric wind” strong enough to remove the components of water from its upper atmosphere, which may have played a significant role in stripping Earth’s twin planet of its oceans, according to new results from the European Space Agency (ESA) Venus Express mission by NASA-funded researchers.

5. How Green (Well, Red) Was My Valley

“Marathon Valley” slices through the rim of a large crater on Mars. It has provided fruitful research targets for our Opportunity rover since July 2015, but now the rover’s team is preparing to move on.

Tracking a Warming Arctic – From Underground to High in the Sky

The Arctic is warming much faster than the rest of Earth. This warming is creating big and small changes, some of which could ripple beyond the planet’s frozen regions and affect us world-wide – possibly raising sea levels, increasing greenhouse warming and affecting wildlife.

Our Arctic Boreal Vulnerability Experiment, known as ABoVE, just began a 10-year mission in Alaska and western Canada, studying these changes.

Underground: Permafrost is the layer of frozen soil beneath some Arctic forests and tundra. 

Like the name suggests, this icy layer stays solid year-round, so when it does melt, it can create big problems. The soil above the thawing permafrost can collapse, creating this wobbly, unstable surface.

7 feet above sea level: As the permafrost thaws, the soil above it can fall away. 

Along the banks of the Itkillik River in Alaska, thawing permafrost has dripped into the water, eroding the cliff side. Known as the “Stinky Bluffs,” this permafrost contains lots of frozen organic matter from dead plants and animals. As the permafrost thaws, this organic matter doesn’t just smell, it also releases carbon dioxide and methane into the atmosphere, adding to the warming effect.

446 feet above sea level: Wildfires aren’t unusual in the forests and shrub lands of Alaska, but as the climate continues to warm, they burn longer and do more damage. 

People who live off the land in the region help researchers understand where plant life isn’t growing back after fires.

100-1000 feet above sea level: Researchers set up 100-foot tall towers at strategic locations throughout Alaska to measure carbon dioxide and methane emissions from right above the forest canopy. 

This provides an up-close look at what gases are released or absorbed from the trees, or swirl in from neighboring regions. These data are combined with measurements taken from airplanes and satellites to create a clearer picture of how much carbon is entering the atmosphere.

3,369 feet above sea level: Dall sheep live in several Alaskan mountain ranges, where they’re critical to both the tourism and sports hunting economies.

Changes in temperature and vegetation can profoundly affect their behavior, like grazing habits, and so researchers study how changing plant life and snow cover affect the sheep.

100-30,000 feet above sea level: Carbon emissions in the air come from thawing permafrost, fossil fuel burning, decaying vegetation and wildfires burning across the Arctic-boreal regions. 

One experiment in the ABoVE campaign measures these emissions with instruments on a DC-8 plane.

About 30,000 feet about sea level: When wildfires burn through vegetation, the effects extend far beyond what we see on the ground. 

Fires release carbon stored in the plants into the atmosphere, where it affects air quality and contributes to the greenhouse effect.

438 miles: Our ABoVE campaign combines research on the ground and from planes with data collected by a fleet of Earth-observing satellites, orbiting Earth hundreds of miles above the surface. 

Data from these satellites provides information on vegetation, atmospheric particles and gasses, and how humans are impacting our planet. With all these data sets analyzed by computer programs, the result is a comprehensive picture of our warming planet.

Unveiling the Center of Our Milky Way Galaxy

We captured an extremely crisp infrared image of the center of our Milky Way galaxy. Spanning more than 600 light-years, this panorama reveals details within the dense swirls of gas and dust in high resolution, opening the door to future research into how massive stars are forming and what’s feeding the supermassive black hole at our galaxy’s core.

Among the features coming into focus are the jutting curves of the Arches Cluster containing the densest concentration of stars in our galaxy, as well as the Quintuplet Cluster with stars a million times brighter than our Sun. Our galaxy’s black hole takes shape with a glimpse of the fiery-looking ring of gas surrounding it.

The new view was made by the world’s largest airborne telescope, the Stratospheric Observatory for Infrared Astronomy, or SOFIA.

Solar System: 10 Things to Know This Week...Halloween Edition!

This week, we're getting into the Halloween spirit with 10 spooktacular things to let your imagination run wild. 

It's not Halloween without our favorite scary characters, but what if they could stop bothering us Earthlings and go far, far away? We begin with where Dracula, Frankenstein, and other creepy creatures might choose to live if the galaxy were theirs to claim...

1. The dark (k)night.

The prince of darkness himself, Dracula, can finally seek sweet respite from the Sun. We think he'd love to live on a rocky planet named YZ Ceti d that orbits so close to its red star that it's tidally locked keeping one side of the planet in perpetual nighttime and the other side in perpetual daytime, with a brilliant red sky (though we can guess which side Dracula will prefer). 

2. Where art thou, werewolves? 

Home sweet home for our furry Full Moon friends might just be on Trappist-1, a planetary system with seven planets—and where standing on one planet would mean the other planets look like six moons (some as big as our Moon in the sky). 

3. Left in the dust. 

We couldn't think of anyone better to live on Proxima b than The Mummy. Hopefully this ancient monster can finally rest in peace on an exoplanet that scientists theorize is a desert planet once home to ancient oceans. 

4. Cloudy with a chance of Frankenstein.

One scientific experiment we'd like to conduct: whether Frankenstein would rather live on HAT-P-11b or Kepler-3b, theorized to have fierce thunderstorms and lightning. 

5. The walking dead. 

We're pretty confident that if zombies were to pick a planet, they'd want one that shares their love of death and destruction. We think they'd feel right at home on one of the pulsar planets, which are scorched by radiation because they orbit a dead star. 

6. Rest your weary bones. 

Skeletons need look no further: Osiris, an exoplanet that's so close to a star that it's "losing its flesh" as the star destroys it, seems like a perfect match. 

7. Enough of the scary stuff. 

For kids out there, turn pumpkin decorating into an out-of-this-world activity with space-themed stencils, from Saturn to the Sun. 

8. Spooky sounds. 

Cassini's radio emissions from Saturn could give creaky doors and howling winds a run for their money. Listen to the eerie audio recordings here and find more HERE.

9. Pumpkin-carve like a NASA engineer. 

NASA engineers design and build robots that can fly millions of miles to study other planets for a living—so on Halloween, they can't help but bring that creative thinking to the grand old tradition of pumpkin carving. Take a cue from their creations with these insider tips.

10. Detective for a day. 

From blades of ice on Pluto to a fuzzy, white "bunny" photographed on Mars, become a solar system sleuth and see if you can solve the stellar mysteries in this slideshow (then compare with how scientists cracked the case).

#TBT to 1969: The Restoration of The Apollo Mission Control Center

On July 20, 1969 the Apollo Mission Control Center landed men on the Moon with only seconds of fuel left. 

Just after the spacecraft safely touched down on the lunar surface, Charlie Duke said to the crew, “Roger, Tranquility. We copy you on the ground. You got a bunch of guys about to turn blue—we’re breathing again. Thanks a lot.” The hard work and preparation of the men who stayed back on Earth was what made John F. Kennedy’s dreams of space exploration come true. 

Today, the facility these men worked in has been restored to its Apollo-era appearance, forever preserving this National Historic Landmark.

It took the restoration crew roughly six years to return the Apollo Mission Control Room to its original retro appearance. Every inch of the room was cleaned and restored by workers, enhancing the 1960s pistachio palette seen on the consoles, as well as ridding the room of 50-year-old gum stuck in places people thought would never be found. Let that be a lesson to us all.

From the artifacts sitting on the consoles to the displays projected at the front of the room, every detail has been carefully put in its proper place. Peep the American flag hanging in the back of the room—this flag went to the Moon on Apollo 17, was planted in the ground, then returned home as a souvenir. Next to the flag, a duplicate of the plaque placed on the Moon hangs on the wall.

Perhaps the only aspect of the room that wasn’t preserved was the thick stench of smoke, burnt coffee, banana peels and pizza boxes. But the ashtrays, pipes, cigarettes and coffee mugs sit in the room as reminders of the aroma. And yes, the Styrofoam cup is authentic to the ‘60s—it’s not an original artifact, but we’re certain this one will last for years to come.

In case you’re worried we didn’t get detailed enough, check the binders in the room. Each one is filled with authentic documents that would’ve been used during the Apollo missions. Some of the documents have been recreated, but many of them were copied from originals that employees had saved for 50 years.

Each console was rigged to send tubes throughout the building, often filled with important documents, but also stuffed with sandwiches and cake (all of the essentials to send men to the Moon).

Several of the surviving Apollo alumni visited mission control for the grand opening of the room at the end of June. Except for the smoke, they say the room looks just as they remember it did 50 years ago. It’s one giant leap—back in time.

This week, you can watch us salute our #Apollo50th heroes and look forward to our next giant leap for future missions to the Moon and Mars. Tune in: https://go.nasa.gov/Apollo50thEvents

That Time We Flew Past Pluto…

Two years ago today (July 14), our New Horizons spacecraft made its closest flyby of Pluto…collecting images and science that revealed a geologically complex world. Data from this mission are helping us understand worlds at the edge of our solar system.

The spacecraft is now venturing deeper into the distant, mysterious Kuiper Belt…a relic of solar system formation…to reach its next target. On New Year’s Day 2019, New Horizons will zoom past a Kuiper Belt object known as 2014 MU69.

The Kuiper Belt is a disc-shaped region of icy bodies – including dwarf planets such as Pluto – and comets beyond the orbit of Neptune. It extends from about 30 to 55 Astronomical Units (an AU is the distance from the sun to Earth) and is probably populated with hundreds of thousands of icy bodies larger than 62 miles across, and an estimated trillion or more comets.

Nearly a billion miles beyond Pluto, you may be asking how the spacecraft will function for the 2014 MU69 flyby. Well, New Horizons was originally designed to fly far beyond the Pluto system and explore deeper into the Kuiper Belt. 

The spacecraft carries extra hydrazine fuel for the flyby; its communications system is designed to work from beyond Pluto; its power system is designed to operate for many more years; and its scientific instruments were designed to operate in light levels much lower than it will experience during the 2014 MU69 flyby.

What have we learned about Pluto since its historic flyby in 2015?

During its encounter, the New Horizons spacecraft collected more than 1,200 images of Pluto and tens of gigabits of data. The intensive downlinking of information took about a year to return to Earth! Here are a few things we’ve discovered:

Pluto Has a Heart

This image captured by New Horizons around 16 hours before its closest approach shows Pluto’s “heart.” This stunning image of one of its most dominant features shows us that the heart’s diameter is about the same distance as from Denver to Chicago. This image also showed us that Pluto is a complex world with incredible geological diversity.

Icy Plains

Pluto’s vast icy plain, informally called Sputnik Planitia, resembles frozen mud cracks on Earth. It has a broken surface of irregularly-shaped segments, bordered by what appear to be shallow troughs.

Majestic Mountains

Images from the spacecraft display chaotically jumbled mountains that only add to the complexity of Pluto’s geography. The rugged, icy mountains are as tall as 11,000 feet high.

Color Variations

This high-resolution enhanced color view of Pluto combines blue, red and infrared images taken by the New Horizons spacecraft. The surface of Pluto has a remarkable range of subtle color variations. Many landforms have their own distinct colors, telling a complex geological and climatological story.

Foggy Haze and Blue Atmosphere

Images returned from the New Horizons spacecraft have also revealed that Pluto’s global atmospheric haze has many more layers than scientists realized. The haze even creates a twilight effect that softly illuminates nightside terrain near sunset, which makes them visible to the cameras aboard the spacecraft.

Water Ice

New Horizons detected numerous small, exposed regions of water ice on Pluto. Scientists are eager to understand why water appears exactly where it does, and not in other places.

A Mesmerizing Model of Monster Black Holes

Just about every galaxy the size of our Milky Way (or bigger) has a supermassive black hole at its center. These objects are ginormous — hundreds of thousands to billions of times the mass of the Sun! Now, we know galaxies merge from time to time, so it follows that some of their black holes should combine too. But we haven’t seen a collision like that yet, and we don’t know exactly what it would look like. 

A new simulation created on the Blue Waters supercomputer — which can do 13 quadrillion calculations per second, 3 million times faster than the average laptop — is helping scientists understand what kind of light would be produced by the gas around these systems as they spiral toward a merger.

The new simulation shows most of the light produced around these two black holes is UV or X-ray light. We can’t see those wavelengths with our own eyes, but many telescopes can. Models like this could tell the scientists what to look for. 

You may have spotted the blank circular region between the two black holes. No, that’s not a third black hole. It’s a spot that wasn’t modeled in this version of the simulation. Future models will include the glowing gas passing between the black holes in that region, but the researchers need more processing power. The current version already required 46 days!

The supermassive black holes have some pretty nifty effects on the light created by the gas in the system. If you view the simulation from the side, you can see that their gravity bends light like a lens. When the black holes are lined up, you even get a double lens!

But what would the view be like from between two black holes? In the 360-degree video above, the system’s gas has been removed and the Gaia star catalog has been added to the background. If you watch the video in the YouTube app on your phone, you can moved the screen around to explore this extreme vista. Learn more about the new simulation here.
