These Three Towers Are Only A Small Portion Of The Massive Eagle Nebula.

How did you get to where you are now? and di you always know that this is where you wanted to end up?

Will there be a livestream to the solar eclipse on the NASA website?

Yup! We’ll have a live stream up https://eclipse2017.nasa.gov/eclipse-live-stream They I believe will also be covering events that are happening across the US. A bunch of my office mates here are going across the US to help with the coverage and to collect data! It should be incredibly exciting! 

What did the astronauts on the International Space Station see when they looked upon the Earth from orbit in 2017? See some of the top Earth observations from the year and download these pics, as chosen by our Earth Science and Remote Sensing Unit at the Johnson Space Center in Houston.   Astronauts have used hand-held cameras to photograph the Earth for more than 55 years. Beginning with the Mercury missions in the early 1960s, astronauts have taken more than 1.5 million photographs of the Earth. Today, the International Space Station continues this tradition of Earth observation from human-tended spacecraft. Operational since November 2000, the space station is well suited for documenting Earth features. The orbiting laboratory maintains an altitude of about 250 miles above the Earth, providing an excellent stage for observing most populated areas of the world.

Did you have a favorite astronaut as a kid? If not, who were your inspirations? :)

Of course Mae Jemison was an inspiration, but I didn’t have a favorite. Because how do you pick out of such a great group?

How long did it take to build the rover??

In 2013, researchers published a shape model of asteroid Bennu based on years of observations from Puerto Rico’s Arecibo Observatory. Their model depicted a rough diamond shape. Five years later, the OSIRIS-REx spacecraft has reached the asteroid, and data obtained from spacecraft’s cameras corroborate those ground-based telescopic observations of Bennu. 

The original model closely predicted the asteroid’s actual shape, with Bennu’s diameter, rotation rate, inclination and overall shape presented almost exactly as projected! This video shows the new shape model created using data from OSIRIS-REx’s approach to the asteroid.

One outlier from the predicted shape model is the size of the large boulder near Bennu’s south pole. The ground-based shape model calculated it to be at least 33 feet (10 meters) in height. Preliminary calculations show that the boulder is closer to 164 feet (50 meters) in height, with a width of approximately 180 feet (55 meters).

Also during the approach phase, OSIRIS-REx revealed water locked inside the clays that make up Bennu. The presence of hydrated minerals across the asteroid confirms that Bennu, a remnant from early in the formation of the solar system, is an excellent specimen for the OSIRIS-REx mission to study. Get all the details about this discovery HERE.

Does an ecplispe cause any unusual effects on the Earth?

Yes, and this is one of the things we’re hoping to study more with this eclipse! If you are in totality, you’ll notice a significant temperature drop. We are also expecting to see changes in the Earth’s 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 we’d love to have everyone here helping out! https://eclipse2017.nasa.gov/citizen-explorers

Build it. Test it. Then, Fly it.

Hundreds of pieces of rockets, rocket engines, boosters, space capsules, launch structures and more have been built, tested and prepared to take us on our Journey to Mars. Across the country, America’s space program is hard at work to launch the Orion space capsule on its first uncrewed flight atop the powerful Space Launch System in 2018.  

But enough of the artist concepts, let’s take a look at the real components being made across the country to prepare for this milestone:

Orion Spacecraft

From testing individual bracket strength to space flight tests, the Orion team is testing every component and subsystem of the spacecraft to ensure crew safety, operational reliability and backup systems are built into the spacecraft from the ground up. To date, hundreds of tests have been conducted across the program to verify and validate that Orion’s design, manufacturing and systems integration meet the rigorous requirements for safe human space exploration.

Orion engineers have subjected the spacecraft to deafening sound blasts, Earthquake-like vibrations and hurricane-force winds in preparation for Orion’s next flight. Large structures such as Orion’s crew and service modules were tested at Lockheed Martin’s Waterton Facility in Littleton, Colorado, and our Glenn Research Center’s Plum Brook Station in Sandusky, Ohio. Motor and engine tests have been conducted at Aerojet Rocketdyne’s facility in Sacramento, California, and Orbital ATK’s facilities in Promontory, Utah, and Elkton, Maryland.

Water impact testing of Orion’s landing capabilities were conducted at our Langley Research Center in Hampton, Virginia, and the capsule’s massive parachute system has been tested in various landing scenarios at the U.S. Army’s Yuma Proving Ground in Arizona. Final assembly, integration and pre-flight testing will take place at our Kennedy Space Center in Florida.

Space Launch System

Towering more than 320 feet, the Space Launch System will be the world’s most powerful rocket. Consisting of a core stage and two boosters, RS-25 engines, and the software to power it all, the initial configuration will provide 15 percent more thrust at launch than the Saturn V rocket and carry more than three times the mass of the Space Shuttle. When complete, we’ll be ready to fire up the largest and most powerful rocket ever built on it’s inaugural launch.

At our Michoud Assembly Facility in New Orleans, a talented crew of humans with the latest in machinery is building SLS’s core stage. The core stage is the structural backbone of SLS that stores cryogenic liquid hydrogen and liquid oxygen that feed the vehicle’s four RS-25 engines. 

For two monumental minutes in June, the SLS solid rocket boosters fired up in an amazing display of power as engineers verified their designs in the last full-scale test before SLS’s first flight. The smoke and fire may last only two minutes, but engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, and Orbital ATK in Promontory, Utah, prepared weeks — even months — in advance for that test. 

Launch Site

At our Kennedy Space Center in Florida, teams are hard at work transforming the historic Vehicle Assembly Building for the launches of tomorrow. Like a stairway to the heavens, these upgrades include the building and installation of platforms to access the new Space Launch System rocket. 

Before SLS roars into deep space from Launch Pad 39B, our Ground Systems program continues making significant upgrades and modifications to the historic launch pad to accommodate the new rocket’s shape and size. 

To make room for this new generation of rockets, workers took down the gantry that stood in support of the Space Shuttle program for 30 years and replaced it with, well, not much really. But that was the idea. Whenever SLS heads out to the pad in the future, it's going to bring its support structure with it. With that in mind, Pad 39B will provide all the fluids, electrical, and communications services to the launch platform.

All of this work is essential to get SLS flight ready before it’s maiden voyage and is an important step on our Journey to Mars.

Next Steps

The work happening across the country is preparing us for the first flight of SLS and Orion in 2018. That first, uncrewed test flight is critical to paving the way for future flights that will carry astronauts to deep space, including on a journey to Mars.

Ultimately, the SLS maiden flight will help us prepare for future human missions. During this flight, currently designated Exploration Mission-1, the spacecraft will travel thousands of miles beyond the moon over the course of about a three-week mission.

It will launch on the most powerful rocket in the world and fly farther than any spacecraft built for humans has ever flown. Orion will stay in space longer than any ship for astronauts has done without docking to a space station and return home faster and hotter than ever before.

ICYMI: New sounds from Mars dropped! Turn the volume up to hear our Ingenuity Mars Helicopter flying on the Red Planet.

Captured by our Perseverance Mars Rover, this is the first time a spacecraft on another planet has recorded the sounds of a separate spacecraft. In this audio track, Perseverance used its SuperCam microphone to listen to the Ingenuity helicopter on April 30, 2021 as it flew on Mars for the fourth time.

With Perseverance parked 262 feet (80 meters) from the helicopter’s takeoff and landing spot, the mission wasn’t sure if the microphone would pick up any sound of the flight. Even during flight when the helicopter’s blades are spinning at 2,537 rpm, the sound is greatly muffled by the thin Martian atmosphere. It is further obscured by Martian wind gusts during the initial moments of the flight. Listen closely, though, and the helicopter’s hum can be heard faintly above the sound of those winds.
