This is where they 3D print cool pieces that are needed for the ISS! They use cool carbon fiber materials to make the final product look smooth and flawless. They are also 3D printing that payload attachment fitting for the SLS Block 1B rocket!! I took a video of it actually printing so be on the lookout for that!

NASA’s Transiting Exoplanet Survey Satellite (TESS) 

The Transiting Exoplanet Survey Satellite (TESS) is the next step in the search for planets outside of our solar system, including those that could support life. The mission will find exoplanets that periodically block part of the light from their host stars, events called transits. 

 TESS will survey 200,000 of the brightest stars near the sun to search for transiting exoplanets. The mission is scheduled to launch in 2018.  

The TESS launch date is NLT June 2018 (the current working launch date is April 2018).

Just me meeting my hero Katherine Johnson after interviewing her in the newsroom for another article I’m writing. nbd ((VERY BIG DEAL)) •🚀•🚀• Katherine G. Johnson is a pioneer in American space history. A NASA mathematician, Johnson’s computations have influenced every major space program from Mercury through the Shuttle. She even calculated the flight path for the first American mission space. In 1953, Johnson was contracted as a research mathematician at the Langley Research Center with the National Advisory Committee for Aeronautics (NACA), the agency that preceded NASA. She worked in a pool of women performing math calculations until she was temporarily assigned to help the all-male flight research team, and wound up staying there. Johnson’s specialty was calculating the trajectories for space shots which determined the timing for launches, including the Mercury mission and Apollo 11, the mission to the moon. (at NASA Langley Research Center)

It’s incredible what humans can do on and off of our planet. Here is a view from the International Space Station taken by Engineer and NASA Astronaut, Colonel Tim Kopra.

Power of Pink Provides NASA with Pressure Pictures

They say you show your true colors when you’re under pressure.

Turns out the old saying works for models being tested in wind tunnels as well, specifically those coated with a unique Pressure-Sensitive Paint (PSP) that NASA engineers have used for more than 25 years.

Apollo 10 Audio — Publicly Available Since 1970s

Recent news articles have reported that “newly declassified” audiotapes reveal that Apollo 10 astronauts heard “outer-spacey” music as the spacecraft flew around the far side of the moon in 1969. 

Here are the facts:

While listed as ‘confidential’ in 1969 at the height of the Space Race, Apollo 10 mission transcripts and audio have been publicly available since 1973.  Since the Internet did not exist in the Apollo era, we have only recently provided digital files for some of those earlier missions. The Apollo 10 audio clips were uploaded in 2012, but the mission’s audio recordings have been available at the National Archives since the early 1970s.

As for the likely source of the sounds, Apollo 10 Lunar Module Pilot Gene Cernan told us on Monday, ‘I don’t remember that incident exciting me enough to take it seriously. It was probably just radio interference. Had we thought it was something other than that we would have briefed everyone after the flight. We never gave it another thought.’

If you’d like to listen to the audio file, it is available HERE (starting at 2:50). 

The full transcript is available HERE.

Tiny NASA Cameras to Watch Commercial Lander form Craters on Moon

This little black camera looks like something out of a spy movie — the kind of device one might use to snap discrete photos of confidential documents.

It's about half the size of a computer mouse.

But the only spying this camera — four of them, actually — will do is for NASA researchers wondering what happens under a spacecraft as it lands on the Moon.

It's a tiny technology with a big name — Stereo Camera for Lunar Plume-Surface Studies, or SCALPSS for short — and it will journey to the Moon in 2021 as a payload aboard an Intuitive Machines Nova-C lunar lander spacecraft. Intuitive Machines is one of two U.S. companies delivering technology and science experiments to the lunar surface later this year as part of NASA's Commercial Lunar Payload Services (CLPS) initiative. SCALPSS will provide important data about the crater formed by the rocket plume of the lander as it makes its final descent and landing on the Moon's surface.

As part of the Artemis program, NASA will send robots and humans to study more of the Moon than ever before. The agency plans to establish sustainable lunar exploration by the end of the decade, and has outlined its Artemis Base Camp concept for the lunar South Pole. Landers may deliver multiple payloads very near one another. Data such as that from SCALPSS will prove aid in computer models that inform subsequent landings.

"As we send bigger, heavier payloads and we try to land things in close proximity to each other, first at the Moon then at Mars, this ability to predict landing impacts is very important," said Michelle Munk, principal investigator for SCALPSS at NASA's Langley Research Center in Hampton, Virginia.

The four SCALPSS cameras, which will be placed around the base of the commercial lander, will begin monitoring crater formation from the precise moment a lander's hot engine plume begins to interact with the Moon's surface.

"If you don't see the crater when it starts to form, you can't really model it," said Munk. "You've got to have the start point and the end point and then you can figure out what happened, in between."

The cameras will continue capturing images until after the landing is complete. Those final stereo images, which will be stored on a small onboard data storage unit before being sent to the lander for downlink back to Earth, will allow researchers to reconstruct the crater's ultimate shape and volume.

Testing to characterize the SCALPSS camera and lens took place last year at NASA's Marshall Space Flight Center in Huntsville, Alabama. Researchers conducted radial distortion, field-of-view and depth-of-focus tests among others. They also ran analytical models to better characterize how the cameras will perform. Development of the actual SCALPSS payload took place at Langley. And over the summer, researchers were able to enter the lab to assemble the payload and conduct thermal vacuum and vibration tests.

That lab access involves special approval from officials at Langley, which is currently only giving access to essential employees and high-priority projects to keep employees safe during the ongoing COVID-19 pandemic. SCALPSS was one of the first projects to return to the center. Before they could do that, facilities had to pass safety and hazard assessments. And while on center, the team had to follow strict COVID-19 safety measures, such as wearing masks and limiting the number of people who could be in a room at one time. The center also provided ample access to personal protective equipment and hand sanitizer.

The SCALPSS hardware was completed in late October and will be delivered to Intuitive Machines in February.

"Development and testing for the project moved at a pretty brisk pace with very limited funds," said Robert Maddock, SCALPSS project manager. "This was likely one of the most challenging projects anyone on the team has ever worked on."

But Munk, Maddock and the entire project team have embraced these challenges because they know the images these little cameras collect may have big ripple effects as NASA prepares for a human return to the Moon as part of the Artemis program.

"To be able to get flight data and update models and influence other designs — it's really motivating and rewarding," said Munk.

Hot off the heels of this project, the SCALPSS team has already begun development of a second payload called SCALPSS 1.1. It will be flown by another CLPS commercial lander provider to a non-polar region of the Moon in 2023 and collect data similar to its predecessor. It will also carry two additional cameras to get higher resolution stereo images of the landing area before engine plume interactions begin, which is critical for the analytic models in establishing the initial conditions for the interactions.

NASA’s Artemis program includes sending a suite of new science instruments and technology demonstrations to study the Moon, landing the first woman and next man on the lunar surface in 2024, and establishing a sustained presence by the end of the decade. The agency will leverage its Artemis experience and technologies to prepare for humanity’s the next giant leap – sending astronauts to Mars as early as the 2030s.

The Hunt for New Worlds Continues with TESS

We’re getting ready to start our next mission to find new worlds! The Transiting Exoplanet Survey Satellite (TESS) will find thousands of planets beyond our solar system for us to study in more detail. It’s preparing to launch from our Kennedy Space Center at Cape Canaveral in Florida.

Once it launches, TESS will look for new planets that orbit bright stars relatively close to Earth. We’re expecting to find giant planets, like Jupiter, but we’re also predicting we’ll find Earth-sized planets. Most of those planets will be within 300 light-years of Earth, which will make follow-up studies easier for other observatories.

TESS will find these new exoplanets by looking for their transits. A transit is a temporary dip in a star’s brightness that happens with predictable timing when a planet crosses between us and the star. The information we get from transits can tell us about the size of the planet relative to the size of its star. We’ve found nearly 3,000 planets using the transit method, many with our Kepler space telescope. That’s over 75% of all the exoplanets we’ve found so far!

TESS will look at nearly the entire sky (about 85%) over two years. The mission divides the sky into 26 sectors. TESS will look at 13 of them in the southern sky during its first year before scanning the northern sky the year after.

What makes TESS different from the other planet-hunting missions that have come before it? The Kepler mission (yellow) looked continually at one small patch of sky, spotting dim stars and their planets that are between 300 and 3,000 light-years away. TESS (blue) will look at almost the whole sky in sections, finding bright stars and their planets that are between 30 and 300 light-years away.

TESS will also have a brand new kind of orbit (visualized below). Once it reaches its final trajectory, TESS will finish one pass around Earth every 13.7 days (blue), which is half the time it takes for the Moon (gray) to orbit. This position maximizes the amount of time TESS can stare at each sector, and the satellite will transmit its data back to us each time its orbit takes it closest to Earth (orange).

Kepler’s goal was to figure out how common Earth-size planets might be. TESS’s mission is to find exoplanets around bright, nearby stars so future missions, like our James Webb Space Telescope, and ground-based observatories can learn what they’re made of and potentially even study their atmospheres. TESS will provide a catalog of thousands of new subjects for us to learn about and explore.

The TESS mission is led by MIT and came together with the help of many different partners.
