Robotic “Bees” Are About to Join Astronauts in Space

There are some things only humans can do in space. The rest can be left to robots. To free up valuable time for astronauts living and working aboard the International Space Station, we’re sending three robotic helpers to the orbiting outpost. Developed and built at our Ames Research Center in California’s Silicon Valley, the cube-shaped Astrobee robots will each stay as busy as a bee flying around the space station and assisting crew with routine tasks like maintenance and tracking inventory. The robots will also help researchers on the ground carry out experiments, test new technologies and study human-robot interaction in space. Learning how robots can best work with humans in close proximity will be key for exploring the Moon and other destinations. Get to know more about our new robots headed to space: 

The Astrobee robots were tested inside a special lab at our Ames Research Center where researchers created a mockup of the space station’s interior. 

The flying robots are propelled by fans. They can move in any direction and turn on any axis in space. 

Each robot is equipped with cameras and sensors for navigating inside the space station and avoiding obstacles.

Claw power! Astrobees have a robotic arm that can be attached for handling cargo or running experiments.

Astrobee is battery powered. When its battery runs low, the robot will autonomously navigate and dock to a power station to recharge.

The robots can operate in either fully automated mode or under remote control by astronauts or researchers on Earth.

Astrobee builds on the success of SPHERES, our first-generation robotic assistant that arrived at the space station in 2006.  

Two of the three Astrobee robots are scheduled to launch to space this month from our Wallops Flight Facility in Virginia! Tune in to the launch at www.nasa.gov/live.

May the 4th Be With You

Happy May the 4th! 

How many connections does America’s space program have with the fictional world of Star Wars? More than you might think…

Join us as we highlight a few of the real-world TIE-ins between us and Star Wars:

Space Laser

Lasers in space sounds like something straight out of Star Wars, but it’s also a reality for us. Our own GEDI (yes, like Jedi) instrument will launch later this year to the International Space Station.

GEDI stands for the Global Ecosystem Dynamics Investigation lidar. It will study the height of trees and forests, using three lasers split into eight tracks, and create a 3D map of forests around the planet.

With GEDI’s new tree maps, we’ll get a better understanding of how much carbon is stored in forests all over Earth, and how forests will be able to absorb increasing carbon dioxide in the atmosphere.

The Jedi knights may help protect a galaxy far, far away, but our GEDI will help us study and understand forest changes right here on Earth.

Another JEDI

There’s another Jedi in town and it happens to be orbiting the planet Jupiter. Our Juno spacecraft, which arrived at the gas giant in July 2016, has an instrument on board that goes by the name of JEDI - the Jupiter Energetic Particle Detector Instrument. 

While it doesn’t use a light saber or channel “the force”, it does measure high-energy particles near Jupiter. Data collected with the JEDI instrument will help us understand how the energy of Jupiter’s rotation is being funneled into its atmosphere and magnetosphere. 

Death Star Moon

We know what you’re thinking...”That’s no moon.” But actually, it is! This is a real picture taken by our Cassini spacecraft of Saturn’s moon Mimas. In this view taken on Cassini’s closest-ever flyby of Mimas, the large Herschel Crater dominates, making the moon look like the Death Star. Herschel Crater is 130 kilometers, or 80 miles, wide and covers most of the right of this image. 

We Actually Do Have the Droids You’re Looking For

We have robots roving and exploring all over the solar system, but it's our own “R2” that's most likely to resonate with Star Wars fans. Robonaut 2, launched in 2011, is working along side humans on board the International Space Station, and may eventually help with spacewalks too dangerous for humans. Incidentally, an earlier version of Robonaut bore a strong “facial” resemblance to enigmatic bounty hunter Boba Fett.

Another "droid" seen on the space station was directly inspired by the saga. In 1999, then Massachusetts Institute of Technology (MIT) professor David Miller, showed the original 1977 Star Wars to his students on their first day of class. After the scene where hero Luke Skywalker learns lightsaber skills by sparring with a floating droid “remotes” on the Millennium Falcon, Miller stood up and pointed: "I want you to build me some of those."

The result was "SPHERES," or Synchronized Position Hold, Engage, Reorient, Experimental Satellites.  Originally designed to test spacecraft rendezvous and docking maneuvers, the bowling-ball size mini-satellites can now be powered by smart phones.

A few more TIE ins...

When space shuttle Atlantis left the International Space Station after 2007’s STS-117 mission, it caught a view of the station that looked to some like a TIE fighter. 

The "TIE-ins" go beyond casual resemblance to real engineering. We already use actual ion engines ("TIE" stands for "Twin Ion Engines") on spacecraft like Dawn, currently orbiting the dwarf planet Ceres. In fact, Dawn goes one better with three ion engines.
