Do Mission Control Personnel Go Through as Many Simulations as Astronauts?

Jared Olson:

Mission control personnel go through a lot more simulations than astronauts, as the flight controller needs to develop very specialized skills and knowledge. On the other hand, astronauts in general need to develop the appropriate depth of knowledge across many disciplines. So shorter classes targeted to their needs are used instead to make the best use of their limited time.

I was the robotics instructor for the EVA simulation (or sim) yesterday and the rig (the simulator system) was not behaving for me. Things were up and running quickly, but after I simulated the main robotics computer having a fatal software fault things went downhill. The team rebooted it to recover, as expected, but the rig did not cleanly handle the reboot.

Suddenly it would not accept any commands to the robot arm. The hand controllers were not communicating. And the astronauts' laptop would not connect.

Eventually, I ran out of troubleshooting options and had to tell my three robotics flight controllers in training that all this was unplanned and the sim was not going to go as expected for them. Other disciplines had "scripting priority," as there were controllers who were assigned to use this sim as an evaluation toward their certifications. I did not have the leverage to disrupt the sim by halting the rig to reset the robotics simulator.

Flight controllers go through so many sims partly because of days like this—where, for whatever reason, they don't get as much "content" as we'd like. I told my guys to greencard that the arm simulator was working as expected, which means that they had to pretend they were seeing all the telemetry indications that would normally happen for the arm supporting an EVA. Basically: Just follow along and pretend.

Each simulation is unique in terms of the coordination required with other disciplines, the malfunctions they get to work through, and the timing involved in planning. Throughout their training flow they need to display their ability to work through a broad enough variety of cases before we can call them "certified." How much they get out of each sim can be a roll of the dice.

Turn Your LEGO Bricks Into a Drone With the Flybrix Drone Kit

Now more than ever, it’s important to have a good hobby. Of course, a lot of people—maybe even you—have been obsessed with learning TikTok dances and baking sourdough bread for the last few months, but those hobbies can wear out their welcome pretty fast. So if you or someone you love is looking for something that’s a little more intellectually stimulating, you need to check out the Flybrix LEGO drone kit from Fat Brain Toys.

What is a Flybrix LEGO Drone Kit?

The Flybrix drone kit lets you build your own drones out of LEGO bricks and fly them around your house using your smartphone as a remote control (via Bluetooth). The kit itself comes with absolutely everything you need to start flying almost immediately, including a bag of 56-plus LEGO bricks, a LEGO figure pilot, eight quick-connect motors, eight propellers, a propeller wrench, a pre-programmed Flybrix flight board PCB, a USB data cord, a LiPo battery, and a USB LiPo battery charger. All you’ll have to do is download the Flybrix Configuration Software, the Bluetooth Flight Control App, and access online instructions and tutorials.

Experiment with your own designs.

The Flybrix LEGO drone kit is specifically designed to promote exploration and experimentation. All the components are tough and can totally withstand a few crash landings, so you can build and rebuild your own drones until you come up with the perfect design. Then you can do it all again. Try different motor arrangements, add your own LEGO bricks, experiment with different shapes—this kit is a wannabe engineer’s dream.

For the more advanced STEM learners out there, Flybrix lets you experiment with coding and block-based coding. It uses an arduino-based hackable circuit board, and the Flybrix app has advanced features that let you try your hand at software design.

Who is the Flybrix LEGO Drone Kit for?

Flybrix is a really fun way to introduce a number of core STEM concepts, which makes it ideal for kids—and technically, that’s who it was designed for. But because engineering and coding can get a little complicated, the recommended age for independent experimentation is 13 and up. However, kids younger than 13 can certainly work on Flybrix drones with the help of their parents. In fact, it actually makes a fantastic family hobby.

What Is the Insurrection Act?

The use of military forces to address volatile situations normally under the purview of law enforcement within the United States is a very rare occurrence, and for good reason. Troops are legally forbidden to be involved in domestic law enforcement affairs without prior congressional authorization.

One loophole does exist. It’s the Insurrection Act, and it empowers the president to dispatch soldiers to combat an insurrection, civil disturbance, natural disaster, or terrorist attack on American soil. But actually invoking the Insurrection Act is no simple matter.

The Act was introduced in 1807 and gives the president the authority to direct American troops to intervene in state-level civil unrest in the event local authorities are unable to control the disturbance. (It was amended in 2006 following Hurricane Katrina to include disasters and terrorism.) It’s used sparingly, particularly as modern police forces have become more militarized. The last time the Act was invoked was in 1992, when riots following the acquittal of four police officers tried in the beating of Rodney King consumed Los Angeles.

At the time, the California governor requested military forces—and normally, the president would activate federal troops at the behest of a governor or state legislature. According to the Los Angeles Times, one exception for dispatching soldiers without state approval is an indication that states are violating civil rights, as was the case for several U.S. presidents (Dwight Eisenhower, John F. Kennedy, and Lyndon B. Johnson) who used military forces to back desegregation in Southern states. Alternately, the president would have to believe such events are interfering with a state’s ability to enforce their laws.

Put simply: Military forces are typically sent at the request of the state, but a request isn’t necessary if the president believes troops are needed to restore order.

When states believe local police are being overwhelmed, their preference is to use the National Guard, which is authorized to act as law enforcement on domestic soil.

If the Act is used, the president would first have to issue a proclamation ordering those involved in any disturbance to disperse. If that fails, the president would issue an executive order to activate the military. States would then likely argue against the intrusion of such forces. It is not clear, however, that they would have the legal justification to prevent such an action if the president calls for it.
