Will normal uv protection sunglasses work?

Unfortunately no. They do not block out enough of the sunlight so you could still burn your eyes if you were to use them to look at the Sun. The ISO 12312-2 compliant eclipse glasses are so dark you literally can’t see anything out of them unless you are looking at the Sun. You can find trusted vendors through the links at https://eclipse2017.nasa.gov/safety If you can’t get them in time, you can also make a pinhole projector  https://eclipse.aas.org/eye-safety/projection and watch the eclipse with that. 

What dose it feel like being inside a space suit?

The suit weighs about 300 pounds. We are made neutrally buoyant in the pool, but over time we can become negatively buoyant. The suit can feel heavy, even the bearings can become stiff, so it can be difficult to operate in the suit. With practice and the help of a great spacewalk team, we can make a spacewalk look seamless.

Sample Return Robot Challenge

It’s been a long, technical journey for the seven teams competing this week in Level 2 of our Sample Return Robot Challenge. Over the past five years, more than 50 teams have attempted the $1.5 million competition, which is looking to develop autonomous capabilities in robotics. Basically, we want robots that can think and act on their own, so they can travel to far off places – like Mars – and we can rely on them to work on their own when a time delay or unknown conditions could be factors.

This challenge has two levels, both requiring robots to navigate without human control and Earth-based tools (like GPS or magnetic compassing). The robot has to find samples, pick them up and deliver them to home base. Each of the final seven teams succeeded at Level 1, where they had to find one sample, during previous competition years. Now, they have a shot at the much more difficult Level 2, where they have a two-hour window to locate up to 10 samples of varying point values, but they don’t know where to look or what exactly they’re looking for.

Get to know the final seven, and be sure to cheer them on as we live-stream the competition all day Sept. 4 and 5.

West Virginia University Mountaineers Hailing from: Morgantown, West Virginia # of Team Members:  12

Behind the Name: In West Virginia, we call ourselves mountaineers. We like to explore unknown places and be inspired by nature.

Motivation: To challenge ourselves. Through this venture, we are also hoping to create research and career opportunities for everyone on the team.

Strategy: Keeping things simple. Through participating in SRR challenge during the last three years, we have gone a long way in streamlining our system.

Obstacles: One of the biggest challenges was finding and nurturing the talent of individual team members and coordinating the team in making real progress on time.

Prize Plans: We donated 50 percent of our 2015 Level 2 prize money to create an undergraduate “Robotics Achievement Fellowship” at WVU. The rest of the funding was allocated to support team member professional development, such as traveling to conferences. A similar model will be used if we win in 2016.

Extra Credit:  We did an Easter egg hunt with our robot, Cataglyphis (named after a desert ant with extraordinary navigation capabilities), last year.

Survey Hailing from: Los Angeles, California # of Team Members: Jascha Little

Behind the Name: It's short, simple, and what the robot spends a lot of its time doing.

Team History: We work together, and we all thought the challenge sounded like an excellent way to solve the problem of what to do with all our free time.

Motivation: We are all engineers and software developers that already work on robotics projects. Reading too much sci-fi when we were kids probably got us to this point.

Strategy: We are trying to solve the search-and-return problem primarily with computer vision. This is mostly to reduce cost. Our budget can't handle high quality IMUs or LIDAR.

Prize Plans: Probably build more robots.

Extra Credit: Favorite pop culture robot is Bender (Futurama). Alcoholic robots are the best.

Alabama Astrobotics (The University of Alabama) Hailing from: Tuscaloosa, Alabama # of Team Members: 33

Behind the Name: “Alabama Astrobotics” was chosen to reflect our school affiliation and our mission to design robotics for various space applications.

Team History: Alabama Astrobotics has been involved with other NASA robotics competitions in the past.  So, the team is accustomed to the competition environment.  

Motivation: We are pleased to have advanced to Level 2 in our first year in the competition (the first team to do so), but we are also not satisfied with just advancing.  Our goal is to try to solve Level 2.

Strategy: Our strategy is similar to that used in Level 1.  Our Level 1 approach was chosen so that it would translate to Level 2 as well, thus requiring fewer customizations from Level 1 to Level 2.

Obstacles: As a university team, the biggest challenge was not having all our team members available to work on the robot during the time since Level 1 completed in June. Most of my team members have either graduated or have summer internships, which took them away from campus after Level 1.  Thus, we didn’t have the manpower to address the additional Level 2 technical challenges.

Prize Plans: Any prize money would be donated to the University of Alabama College of Engineering.

Extra Credit: Alabama Astrobotics also competes in the annual NASA Robotic Mining Competition held at the Kennedy Space Center each May.  We have been fortunate enough to win that competition three times in its seven year history, and we are the only team to win it more than once.

MAXed-Out Hailing From: Santa Clara, California # of Team Members: 4

Behind the Name: Several reasons: Team leader is Greg Maxwell, and his school nick name was Max. Our robot’s name is Max, which is one of the most common name for a dog, and it is a retriever. Our efforts on this has been too the max…. i.e. MAXed-Out. Our technology requirements have been pushed to their limits - Maxed-Out.

Team History: Greg Maxwell started a Meet-up “Silicon-Valley Robot Operating System” SV-ROS that was to help teach hobbyists how to use ROS on their robots. We needed a project to help implement and make real what we were teaching. This is the third contest we have participated in.

Motivation: There is still such a long way to go to make robots practical. Every little bit we can contribute makes them a little bit better and smarter. Strategy: Level 1 was a test, as a minimum viable product to prove the tech worked. For Level 2, we had to test and add obstacle avoidance to be able to cover the larger area with trees and slopes, plus add internal guidance to allow for Max to be out of the home base camera tracking system.

Obstacles: Lack of a cost effective robot platform that met all the requirements; we had to build our own. Also time and money. The two months (between Level 1 and 2) went really fast, and we had to abandon lots of cool ideas and focus on the basics.

Prize Plans: Not sure, but pay off the credit cards comes to mind. We might open-source the platform since it works pretty well. Or we will see if it works as expected. We may also take a break / vacation away from robots for a while.

Extra Credit: My nephew, Max Hieges, did our logo, based on the 1960-era Rat Fink sticker.

Mind & Iron Hailing From: Seattle, Washington # of Team Members: 5

Behind the Name: It was the original title for Isaac Asimov’s “I Robot,” and we thought it was a good combination of what a robot actually is – mechanical and brains.

Team History: Three of us were WPI undergrads and met at school; two of us did our master’s degrees at the University of Washington, where we met another member, and then another of us brought on a family member.

Motivation: We saw that there was an opportunity to compete in a challenge that seemed like there was a reasonable solution that we could tackle with a limited budget. We saw three years of competition and thought that we had some better ideas and a pretty good shot at it. Strategy: The samples and the terrain are much more complex in Level 2, and we have to be more careful about our navigation. We are using the same tools, just expanding their capability and scope.

Obstacles: The team being spread over three different time zones has been the biggest challenge. We are all doing this in our free time after work. The internet has been really handy to get things done.

Prize Plans: Probably invest in more robot stuff! And look for other cool projects we can work on, whether it’s another NASA challenge or other projects.

Extra Credit: We are hoping to collaborate with NASA on the professional side with surgical robots to exoskeletons. Challenge-related, our robot is mostly made of plywood – it is a composite fiber material that works well for fast development using cheap materials.

Sirius Hailing From: South Hadley, Massachusetts # of Team Members: 4

Team History: We are a family. Our kids are both robot builders who work for Boston Dynamics, and they have a lot of robot expertise. Both of our kids are robotics engineers, and my wife is intrinsically brilliant, so the combination of that makes for a good team.

Motivation: Because it’s a really hard challenge. It’s one thing to drive a robot with a remote control; it’s another to do the whole thing autonomously. If you make a single change in a robot, it could throw everything off. You have to think through every step for the robot. On a basic level, to learn more about robotics and to win the prize. Strategy: Very similar to Level 1. We approached Level 1 knowing Level 2 was there, so our strategy was no different.

Obstacles: It is very difficult to do object recognition under unpredictable conditions – sun, clouds, weather, sample location. The biggest challenge was trying to recognize known and unknown objects under such a wide variety of environmental possibilities. And the terrain is very different – you don’t know what you’re going to find out there.

Prize Plans: We haven’t really thought about it, but we will give some away, and we’ll invest the rest in our robotics company.

Extra Credit: The first robot we had was called Robo-Dad. Dan was training to be an astronaut in the 1990s, so we built a toy remote-controlled truck that Dan - in Texas - could control via the internet in the house. Robo-Dad had a camera that Dan could see the house with. It had two-way communication; it was a little before it’s time – the internet was very slow.

Team AL Hailing From: Ontario, Canada # of Team Members: 1

Team History: I was looking for competitions that were open, and my dad had followed the Centennial Challenges for a while, so he alerted me to this one. I was already doing rover projects, and it was appropriate and awesome and interesting. I felt like I could do it as a team of one.

Motivation: Difficult challenges. I’m definitely inspired seeing really cool robots that other people are building. New emerging tech really motives me to create new things.

Strategy: I showed up with another robot to Level 2. I built three, but ran with only two. It did make it more complicated, but the strategy was to send them to different areas and have them be able to communicate with each other. Everything physically was the same from Level 1.  The idea is that they would all go out with different missions and I would maximize field coverage.

Obstacles: Time. More time would always be nice. Being able to make something like this happen under a timeline is really difficult. I feel like I accomplished a lot for a year. Also, manpower – being a team of 1, I have to do all of the paperwork and other related stuff, but also carry the hardware and do the programming. You have to multitask a lot.

Prize Plans: I’d like to start a robotics company, and be able to expand some of the things I’ve been working on associated with technology and maker education.

Extra Credit: My story is not linear. A lot of people are surprised to hear that my background is in molecular biology and  research. I once lived in a tent in Madagascar for a few months to do a biodiversity study, and I have multiple publications from that side of my life. I am in a whole different place now.

The competition is one of many run by our Centennial Challenges program, which looks to the public – citizen inventors, academics, makers, artists, YOU – to help us advance technology and bring a different perspective to obstacles that gets us outside of our traditional solving community. See what else we’re working on here.

Perfect 10: A Decade of Studying Ice from the Sky

From 2009 through 2019, our Operation IceBridge flew planes above the Arctic, Antarctic and Alaska, measuring the height, depth, thickness, flow and change of sea ice, glaciers and ice sheets.

IceBridge was designed to “bridge” the years between NASA’s two Ice, Cloud, and land Elevation Satellites, ICESat and ICESat-2. IceBridge made its final polar flight in November 2019, one year after ICESat-2’s successful launch.

A lot of amazing science happens in a decade of fundamentally changing the way we see ice. Here, in chronological order, are 10 of IceBridge’s most significant and exciting achievements.

2009: Go for launch

The first ICESat monitored ice, clouds, atmospheric particles and vegetation globally beginning in 2003. As ICESat neared the end of its life, we made plans to keep measuring ice elevation with aircraft until ICESat-2’s launch.

ICESat finished its service in August 2009, leaving IceBridge in charge of polar ice tracking for the next decade.

2009: Snow on sea ice

To measure how thick sea ice is, we first have to know how much snow is accumulated on top of the ice. Using a snow radar instrument, IceBridge gathered the first widespread data set of snow thickness on top of both Arctic and Antarctic sea ice.

2009: Getting to the bottom of glaciers 

IceBridge mapped hundreds of miles of grounding lines in both Antarctica and Greenland. Grounding lines are where a glacier’s bottom loses contact with the bedrock and begins floating on seawater – a grounding line that is higher than rock that the ice behind it is resting on increases the possibility of glaciers retreating in the future. 

The team mapped 200 glaciers along Greenland’s coastal areas, as well as coastal areas, the interior of the Greenland Ice Sheet and high-priority areas in Antarctica.

2011: Spotting cracks in the ice

While flying Antarctica in 2011, IceBridge scientists spotted a massive crack in Pine Island Glacier, one of the fastest-changing glaciers on the continent. The crack produced a new iceberg that October.

Pine Island has grown thinner and more unstable in recent decades, spawning new icebergs almost every year. IceBridge watched for cracks that could lead to icebergs and mapped features like the deep water channel underneath Pine Island Glacier, which may bring warm water to its underside and make it melt faster.

2013: Making a map of rock

Using surface elevation, ice thickness and bedrock topography data from ICESat, IceBridge and international partners, the British Antarctic Survey created an updated map of the bedrock beneath Antarctic ice.

Taking gravity and magnetic measurements helps scientists understand what kind of rock lies below the ice sheet. Soft rock and meltwater make ice flow faster, while hard rock makes it harder for the ice to flow quickly.

2013: Surprises under the ice

IceBridge’s airborne radar data helped map the bedrock underneath the Greenland Ice Sheet, revealing a previously unknown canyon more than 400 miles long and up to a half mile deep slicing through the northern half of the country.

The “grand canyon” of Greenland may have once been a river system, and today likely transports meltwater from Greenland’s interior to the Arctic Ocean.

2015: It’s what’s inside (the ice sheet) that counts

After mapping the bedrock under the Greenland Ice Sheet, scientists turned their attention to the middle layers of the ice. Using both ice-penetrating radar and ice samples taken in the field, IceBridge created the first map of the ice sheet’s many layers, formed as thousands of years of snow became compacted downward and formed ice.

Making the 3D map of Greenland’s ice layers gave us clues as to how the ice sheet has warmed in the past, and where it may be frozen to bedrock or slowly melting instead.

2018: Gap bridged!

ICESat-2 launched on September 15, 2018, rocketing IceBridge into the final phase of its mission: Connecting ICESat and ICESat-2.

IceBridge continued flying after ICESat-2’s launch, working to verify the new satellite’s measurements. By conducting precise underflights, where planes traced the satellite’s orbit lines and took the same measurements at nearly the same time, the science teams could compare results and make sure ICESat-2’s instruments were functioning properly.

2018: An impact crater under the ice

Using IceBridge data, an international team of scientists found an impact crater from a meteor thousands of years in the past. The crater is larger than the city of Washington, D.C., likely created by a meteor more than half a mile wide.

2019: Flying into the sunset

In 2019, IceBridge continued flying in support of ICESat-2 for its Arctic and Antarctic campaigns. The hundreds of terabytes of data the team collected over the decade will fuel science for years to come.

IceBridge finished its last polar flight on November 20, 2019. The team will complete one more set of Alaska flights in 2020.

It Takes a Nation to #LaunchAmerica!

Image Credit: NASA/Roscosmos

As we celebrate 20 years of humans living and working on the International Space Station, we’re also getting ready for another space milestone: Crew-1, this weekend’s trip to the ISS aboard the SpaceX Crew Dragon Resilience and the first certified crew rotation flight to the International Space Station.

Crew-1 is scheduled to lift off Saturday at 7:49 PM EST, from our Kennedy Space Center—but across the United States, teams from NASA and SpaceX will be hard at work sending our astronauts into orbit!

Image Credit: NASA/Fred Deaton

At Marshall Space Flight Center’s Huntsville Operations Support Center (HOSC), for example, engineers with our Commercial Crew Program have been helping review the design and oversee safety standards for SpaceX’s Falcon 9 rocket, making sure it’s ready to carry humans to the Space Station.

This Saturday, they’ll be in the HOSC to monitor launch conditions and watch the data as Crew-1 blasts off, helping future commercially-operated missions to the ISS run even more smoothly.

Image Credit: NASA/Emmett Given

Long before Crew-1, though, Marshall has been keeping things active on board the ISS. For decades, the Payload Operations and Integration Center, also located in the HOSC, has been “science central” for the Space Station, coordinating and keeping track of the scientific experiments taking place—24/7, 365 days a year.

With the Space Station’s population soon to jump from three to seven, our ISS crew will be able to spend up to 70 hours a week on science, helping us learn how to live in space while making life better on Earth!

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?

Pluto the Small Dwarf Planet

Tired of singing the same holiday songs? Here’s a celestial take on the classic Rudolph the Red Nose Reindeer that you can introduce to your friends and family.

(Three infrared wavelength ranges were placed into the three color channels (red, green and blue, respectively) to create this false color Christmas portrait.)

Sung to the tune of Rudolph the Red Nosed Reindeer

Intro You know Mercury, Venus and Earth and Mars, too Jupiter, Saturn, Uranus, and Neptune But do you recall the most famous Solar System body of all

Verse 1 Pluto the small dwarf planet Has a very shiny glow And if you had discovered it Your name might be Clyde Tombaugh

Verse 2 All of the other planets  used to laugh and call him names They never let poor Pluto join in planetary games

Verse 3 Then one fateful summer eve New Horizons came to say “Pluto with your heart so bright Won’t you let me flyby tonight?”

Verse 4 Then all the planets loved him and they shouted out with glee, “NASA!” Pluto the small dwarf planet You’ll go down in history!

(repeat V3 and V4)

This song was written by Andres Almeida, a NASA employee, for a holiday office party. It’s a fun take on the classic Rudolph the Red Nosed Reindeer, with a NASA spin. Enjoy!

Eclipse Across America

August 21, 2017, the United States experienced a solar eclipse! 

An eclipse occurs when the Moon temporarily blocks the light from the Sun. Within the narrow, 60- to 70-mile-wide band stretching from Oregon to South Carolina called the path of totality, the Moon completely blocked out the Sun’s face; elsewhere in North America, the Moon covered only a part of the star, leaving a crescent-shaped Sun visible in the sky.

During this exciting event, we were collecting your images and reactions online. 

Here are a few images of this celestial event...take a look:

This composite image, made from 4 frames, shows the International Space Station, with a crew of six onboard, as it transits the Sun at roughly five miles per second during a partial solar eclipse from, Northern Cascades National Park in Washington. Onboard as part of Expedition 52 are: NASA astronauts Peggy Whitson, Jack Fischer, and Randy Bresnik; Russian cosmonauts Fyodor Yurchikhin and Sergey Ryazanskiy; and ESA (European Space Agency) astronaut Paolo Nespoli.

Roman’s Heat-Vision Eyes Are Complete!

Our Nancy Grace Roman Space Telescope team recently flight-certified all 24 of the detectors the mission needs. When Roman launches in the mid-2020s, the detectors will convert starlight into electrical signals, which will then be decoded into 300-megapixel images of huge patches of the sky. These images will help astronomers explore all kinds of things, from rogue planets and black holes to dark matter and dark energy.

Eighteen of the detectors will be used in Roman’s camera, while another six will be reserved as backups. Each detector has 16 million tiny pixels, so Roman’s images will be super sharp, like Hubble’s.

The image above shows one of Roman’s detectors compared to an entire cell phone camera, which looks tiny by comparison. The best modern cell phone cameras can provide around 12-megapixel images. Since Roman will have 18 detectors that have 16 million pixels each, the mission will capture 300-megapixel panoramas of space.

The combination of such crisp resolution and Roman’s huge view has never been possible on a space-based telescope before and will make the Nancy Grace Roman Space Telescope a powerful tool in the future.
