More Than Just Dust In The Wind

From space, we can see a swirling brown mass making its way across the Atlantic – dust from the Sahara Desert – the largest hot desert in the world. It’s a normal phenomenon. Every year, winds carry millions of tons of dust from North Africa, usually during spring and summer in the Northern Hemisphere.

Dust clouds this large can affect air quality in regions where the dust arrives. The particles can also scatter the Sun’s light, making sunrises and sunsets more vibrant.

Dust particles in the air are also known as aerosols. We can measure aerosols, including dust, sea salt and smoke, from satellites and also use computer models to study how they move with the wind.

Following the transport of dust from space shows us how one of the driest places on Earth plays a role in fertilizing the Amazon rainforest. There are minerals in Saharan dust, like phosphorous, that exist in commercial fertilizers, helping seed the rainforest.

NASA Spotlight: Astronaut Soichi Noguchi

NASA Spotlight: Astronaut Soichi Noguchi

Soichi Noguchi was selected as an astronaut with the Japan Aerospace Exploration Agency in 1996. A native of Yokohama, Kanagawa, he is currently a mission specialist for NASA’s SpaceX Crew-1 launch taking flight to the International Space Station on Nov. 14. Soichi will be the first international crewmember on Crew Dragon and the first international partner astronaut to fly aboard three types of orbital spacecraft – the U.S. space shuttle, the Russian Soyuz, and now the SpaceX Crew Dragon! Talk about impressive. He received a B.S. in Aeronautical Engineering in 1989, master’s degree in Aeronautical Engineering in 1991, Doctor of Philosophy in Advanced Interdisciplinary Studies in 2020, all from the University of Tokyo.

Soichi took time from preparing for his historic mission to answer questions about his life and career: 

You recently earned a doctorate in philosophy. What made you do it?

After my second flight, I started this research about your sensory system in zero gravity. I used a my own personal video, which I took during my last two flights at the International Space Station. I had a lot of interesting discussions amongst young professionals and students at the University of Tokyo about the research. It was a fun experience – but I would not do it again!

Space is a risky business. Why do it?

Space IS definitely a risky business. But the reward is higher than the risk so that’s why we take it.

Do you have a message for boys and girls in Japan who are interested in science and engineering?

Three words: Space. Is. Waiting.

NASA Spotlight: Astronaut Soichi Noguchi

Aside from mission objectives and tasks, what’s a personal goal for this mission?

We have a lot of interesting missions to do, but my personal goal is to return home with lots of fun stories.

NASA Spotlight: Astronaut Soichi Noguchi

What was it like to get the phone call to become an astronaut?

 It was 25 years ago, but I still remember the voice vividly. I got a call from Dr. Mamoru Mohri, the very first JAXA astronaut, and he said “Welcome to the Astronaut Corps.” When I got the call to be part of the Crew-1 mission, I was a lot less nervous than when I was assigned to my first mission, but the excitement remains the same.

Can you describe your crew mate Mike Hopkins in one sentence?

He is a natural leader that takes care of the team really well, and he’s fun to play around with.

Star Trek or Star Wars?

Star Wars… just because!

NASA Spotlight: Astronaut Soichi Noguchi

Can you share your favorite photo or video that you took in space?

My favorite photo is Mount Fuji because I see the mountain almost every day when I was a child. It’s definitely breathtaking to see Mount Fuji from space.

image

What personal items did you decide to pack for launch and why?

I have lots of family photos, and I would put it inside my sleep station. Definitely one of the most challenging things about spaceflight is not experiencing zero gravity, not the rocket, but time away from family.

How would you describe spacewalking outside the space station?

It’s an excursion. The view of the Earth is just breathtaking because you are just one glass away from the vacuum of space. There’s nothing between you and Earth.

image

What are you most excited about for the future of human space exploration?

I would say I’m most excited for interplanetary travel to become more common so that the school kids can go to Mars on their field trip.

What would you say to someone looking to follow in your footsteps?

Don’t worry, be happy!

How has spaceflight evolved since your first launch and stay aboard the International Space Station in 2005?

This is definitely an exciting moment. We’re starting to see more players in the game. SpaceX is the frontrunner, but soon we’ll see Boeing, Sierra Nevada and Axiom. So the International Space Station will soon have more players involved, and it will be a lot more fun!

Thank you for your time, Soichi, and good luck on your historic mission! Get to know a bit more about Soichi and his NASA astronaut crew mates Victor Glover, Michael Hopkins, and Shannon Walker in the video above.

Top 10 Things to Know for the Return of our Launch America Mission With SpaceX

image

History was made May 30 when NASA astronauts Robert Behnken and Douglas Hurley launched from American soil in a commercially built and operated American crew spacecraft on its way to the International Space Station. 

Pictured above is the SpaceX Dragon Endeavour spacecraft that lifted off on the company’s Falcon 9 rocket from Launch Complex 39A at Kennedy Space Center in Florida and docked with the space station on May 31. Now, Behnken and Hurley are ready to return home in Endeavour for a splashdown off the coast of Florida, closing out a mission designed to test SpaceX’s human spaceflight system, including launch, docking, splashdown, and recovery operations. Undocking is targeted for 7:34 p.m. ET on August 1, with splashdown back to Earth slated for 2:42 p.m. on August 2. Watch our continuous live coverage HERE. 

1. Where will Behnken and Hurley splash down?

image

Image: SpaceX’s Crew Dragon is guided by four parachutes as it splashes down in the Atlantic on March 8, 2019, after the uncrewed spacecraft’s return from the International Space Station on the Demo-1 mission.

Together with SpaceX, we are capable of supporting seven splashdown sites off the coast of Florida. The seven potential splashdown sites for the Dragon Endeavor are off the coasts of Pensacola, Tampa, Tallahassee, Panama City, Cape Canaveral, Daytona, and Jacksonville.

2. How will a splashdown location be chosen?

Splashdown locations are selected using defined priorities, starting with selecting a station departure date and time with the maximum number of return opportunities in geographically diverse locations to protect for weather changes. Teams also prioritize locations which require the shortest amount of time between undocking and splashdown based on orbital mechanics, and splashdown opportunities that occur in daylight hours.

Check out the Departure and Splashdown Criteria Fact Sheet for an in-depth look at selecting return locations, decision points during return, and detailed weather criteria.

3. How long will it take for Behnken and Hurley to return to Earth?

image

Return time for Behnken and Hurley will vary depending on the undock and splashdown opportunities chosen, with the primary opportunity taking between six and 30 hours.

4. What does the return look like? What are the major milestones?

image

Crew Dragon’s return home will start with undocking from the International Space Station. At the time of undock, Dragon Endeavour and its trunk weigh approximately 27,600 pounds. We will provide live coverage of the return from undocking all the way through splashdown.

There will be two very small engine burns immediately after hooks holding Crew Dragon in place retract to actually separate the spacecraft from the station. Once flying free, Dragon Endeavour will autonomously execute four departure burns to move the spaceship away from the space station and begin the flight home. Several hours later, one departure phasing burn, lasting about six minutes, puts Crew Dragon on the proper orbital path to line it up with the splashdown zone.

Shortly before the final deorbit burn, Crew Dragon will separate from its trunk, which will burn up in Earth’s atmosphere. The spacecraft then executes the deorbit burn, which commits Crew Dragon to return and places it on an orbit with the proper trajectory for splashdown. After trunk separation and the deorbit burn are complete, the Crew Dragon capsule weighs approximately 21,200 pounds.  

5. How fast will Dragon Endeavour be going when it re-enters the Earth’s atmosphere? How hot will it get?

Crew Dragon will be traveling at orbital velocity prior to re-entry, moving at approximately 17,500 miles per hour. The maximum temperature it will experience on re-entry is approximately 3,500 degrees Fahrenheit. The re-entry creates a communications blackout between the spacecraft and Earth that is expected to last approximately six minutes.

6. When do the parachutes deploy?

image

Image: SpaceX’s final test of Crew Dragon’s Mark 3 parachute system on Friday, May 1, 2020, that will be used during the Demo-2 splashdwon mission. 

Dragon Endeavour has two sets of parachutes will that deploy once back inside Earth’s atmosphere to slow down prior to splashdown. Two drogue parachutes will deploy at about 18,000 feet in altitude while Crew Dragon is moving approximately 350 miles per hour. Four main parachutes will deploy at about 6,000 feet in altitude while Crew Dragon is moving approximately 119 miles per hour.

7. Who recovers the crew and the Dragon Endeavour capsule from the water? What vehicles and personnel are involved?

image

For splashdown at any of the seven potential sites, SpaceX personnel will be on location to recover the capsule from the water. Two recovery ships, the Go Searcher and the Go Navigator, split locations between the Gulf of Mexico and the Atlantic Ocean off the coast of Florida. On either ship will be more than 40 personnel from SpaceX and NASA, made up of spacecraft engineers, trained water recovery experts, medical professionals, the ship’s crew, NASA cargo experts, and others to assist in the recovery.

8. How long after splashdown until Behnken and Hurley are out of the capsule?

image

Immediately after splashdown has occurred, two fast boats with SpaceX personnel deploy from the main recovery ship. The first boat checks capsule integrity and tests the area around the Crew Dragon for the presence of any hypergolic propellant vapors. Once cleared, the personnel on the boats begin preparing the spaceship for recovery by the ship. The second fast boat is responsible for safing and recovering Crew Dragon’s parachutes, which have at this point detached from the capsule and are in the water.

At this point the main recovery vessel can move in and begin to hoist the Crew Dragon capsule onto the main deck. Once the capsule is on the recovery vessel, it is moved to a stable location for the hatch to be opened for waiting medical professionals to conduct initial checks and assist Behnken and Hurley out of Dragon Endeavour.

This entire process is expected to take approximately 45 to 60 minutes, depending on spacecraft and sea state conditions.

9. Where do Behnken and Hurley go after they are out of the capsule?

Immediately after exiting the Crew Dragon capsule, Behnken and Hurley will be assisted into a medical area on the recovery ship for initial assessment. This is similar to procedures when welcoming long-duration crew members returning home on Soyuz in Kazakhstan.

After initial medical checks, Behnken and Hurley will be returned to shore either by traveling on the primary recovery ship or by helicopter. Helicopter returns from the recovery ship are the baseline for all splashdown zones except for the Cape Canaveral splashdown site, with travel times ranging from approximately 10 minutes to 80 minutes. The distance from shore will be variable depending on the splashdown location, ranging from approximately 22 nautical miles to 175 nautical miles.

Once returned to shore, both crew members will immediately board a waiting NASA plane to fly back to Ellington field in Houston.

10. What happens next?

Meanwhile, Dragon Endeavour will be returned back to the SpaceX Dragon Lair in Florida for inspection and processing. Teams will examine the data and performance of the spacecraft throughout the test flight to complete the certification of the system to fly operational missions for our Commercial Crew and International Space Station Programs. The certification process is expected to take about six weeks. Following successful certification, the first operational mission will launch with Crew Dragon commander Michael Hopkins, pilot Victor Glover, and mission specialist Shannon Walker – all of NASA – along with Japan Aerospace Exploration Agency (JAXA) mission specialist Soichi Noguchi will launch on the Crew-1 mission from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The four crew members will spend six months on the space station.

The launch is targeted for no earlier than late-September.

What We Learned from Flying a Helicopter on Mars

The Ingenuity Mars Helicopter made history – not only as the first aircraft to perform powered, controlled flight on another world – but also for exceeding expectations, pushing the limits, and setting the stage for future NASA aerial exploration of other worlds.

Built as a technology demonstration designed to perform up to five experimental test flights over 30 days, Ingenuity performed flight operations from the Martian surface for almost three years. The helicopter ended its mission on Jan. 25, 2024, after sustaining damage to its rotor blades during its 72nd flight.

So, what did we learn from this small but mighty helicopter?

We can fly rotorcraft in the thin atmosphere of other planets.

Ingenuity proved that powered, controlled flight is possible on other worlds when it took to the Martian skies for the first time on April 19, 2021.

Flying on planets like Mars is no easy feat: The Red Planet has a significantly lower gravity – one-third that of Earth’s – and an extremely thin atmosphere, with only 1% the pressure at the surface compared to our planet. This means there are relatively few air molecules with which Ingenuity’s two 4-foot-wide (1.2-meter-wide) rotor blades can interact to achieve flight.

Ingenuity performed several flights dedicated to understanding key aerodynamic effects and how they interact with the structure and control system of the helicopter, providing us with a treasure-trove of data on how aircraft fly in the Martian atmosphere.

Now, we can use this knowledge to directly improve performance and reduce risk on future planetary aerial vehicles.

NASA’s Ingenuity Mars Helicopter took this black-and-white photo while hovering over the Martian surface on April 19, 2021, during the first instance of powered, controlled flight on another planet. It used its navigation camera, which is mounted in its fuselage and pointed directly downward to track the ground during flight. The image shows the shadow of the Ingenuity Mars Helicopter on the surface of Mars. The black shadow of the helicopter is very crisp and clear against the white backdrop of the Martian sandy surface. Its wing-shaped rotors jut out from the sides of its square body, and from each corner is a thin leg that has a small ball shape at the end. Credit: NASA/JPL-Caltech

Creative solutions and “ingenuity” kept the helicopter flying longer than expected.

Over an extended mission that lasted for almost 1,000 Martian days (more than 33 times longer than originally planned), Ingenuity was upgraded with the ability to autonomously choose landing sites in treacherous terrain, dealt with a dead sensor, dusted itself off after dust storms, operated from 48 different airfields, performed three emergency landings, and survived a frigid Martian winter.

Fun fact: To keep costs low, the helicopter contained many off-the-shelf-commercial parts from the smartphone industry - parts that had never been tested in deep space. Those parts also surpassed expectations, proving durable throughout Ingenuity’s extended mission, and can inform future budget-conscious hardware solutions.

There is value in adding an aerial dimension to interplanetary surface missions.

Ingenuity traveled to Mars on the belly of the Perseverance rover, which served as the communications relay for Ingenuity and, therefore, was its constant companion. The helicopter also proved itself a helpful scout to the rover.

After its initial five flights in 2021, Ingenuity transitioned to an “operations demonstration,” serving as Perseverance’s eyes in the sky as it scouted science targets, potential rover routes, and inaccessible features, while also capturing stereo images for digital elevation maps.

Airborne assets like Ingenuity unlock a new dimension of exploration on Mars that we did not yet have – providing more pixels per meter of resolution for imaging than an orbiter and exploring locations a rover cannot reach.

Tech demos can pay off big time.

Ingenuity was flown as a technology demonstration payload on the Mars 2020 mission, and was a high risk, high reward, low-cost endeavor that paid off big. The data collected by the helicopter will be analyzed for years to come and will benefit future Mars and other planetary missions.

Just as the Sojourner rover led to the MER-class (Spirit and Opportunity) rovers, and the MSL-class (Curiosity and Perseverance) rovers, the team believes Ingenuity’s success will lead to future fleets of aircraft at Mars.

In general, NASA’s Technology Demonstration Missions test and advance new technologies, and then transition those capabilities to NASA missions, industry, and other government agencies. Chosen technologies are thoroughly ground- and flight-tested in relevant operating environments — reducing risks to future flight missions, gaining operational heritage and continuing NASA’s long history as a technological leader.

You can fall in love with robots on another planet.

Following in the tracks of beloved Martian rovers, the Ingenuity Mars Helicopter built up a worldwide fanbase. The Ingenuity team and public awaited every single flight with anticipation, awe, humor, and hope.
