The Curious Life of a Mars Rover

As you read this, there are multiple robots hanging out on Mars, sending back data. If you're a space geek like me, you may have watched the rover Curiosity land in 2012. But I didn't see the Spirit and Opportunity landings in 2003, and I frankly never spent the time to read up on all the tiny details of the launch and landing processes for all of these rovers.

In this 25-minute video, NASA engineer Kobie Boykins gives us more than 10 years of Mars rover history, packed into a super-entertaining presentation. In the first eight minutes or so, Boykins runs through the launch, landing, and early stages of the Spirit and Opportunity missions, then he dives into some of the most interesting things they discovered, and how it was done. It's really fun to see someone who worked on these projects explain what's interesting about them. (He designed parts of all these rovers.) Take 25 minutes and geek out on this:

Some things to watch for in the launch/land sequences—note which parts of the system fall back to Earth and are reused, which fall into the ocean on Earth, and which bits end up as debris on Mars. I was also surprised to learn all the technical details about Curiosity around the 15-minute mark (including 6-wheel drive, 4-wheel steering). Also, the note (around 19 minutes in) that Mars has clouds. Awesome. Finally, 24 minutes in, a special version of the pale blue dot.

NASA Could Be Sending Autonomous Bee Drones to Mars

While NASA is inching closer to landing humans on Mars, a team from Japan and the U.S. is working on exporting something else to the red planet: robot bees. As Co.Design reports, the engineers believe their hive of drones, dubbed Marsbees, could be used to explore the surface of Mars autonomously.

The project is one of a handful being funded by NASA in 2018 as part of the space agency’s Innovative Advanced Concepts program. According to the initial designs, the Marsbees would collect data and images from Mars just like the Curiosity and Opportunity rovers do now. But the drones' small size and large numbers give them a few key advantages.

The Marsbees would be carted onto the planet by way of a conventional rover that acts as a roaming beehive. The bumblebee-sized drones would use flapping apparatuses the size of cicada wings to fly around Mars, capturing data individually or swarming together to analyze larger swaths of land. If one robot fails, there would be more to make up for the missing sensor, and after gathering enough information they could return to the ground-based hub to recharge and relay the data back to Earth.

The team still needs to perfect a prototype before the swarms of Martian bees can become a reality. Wing size is a crucial factor, since the atmosphere on Mars is thinner than it is on Earth. Once they have that design element in place, the engineers still need to prove their drones can take off, land, navigate through the air, and complete missions. They hope to tackle each of those points in the first phase of the project using a $125,000 grant from NASA.

Send Your Name to Space on NASA's Latest Mars Lander

Humans may not reach Mars until the 2030s (optimistically), but you can get your name there a whole lot sooner. As Space.com reports, NASA is accepting names from the public to be engraved on a small silicon microchip that's being sent into space with their latest Mars lander, InSight.

All you have to do is submit your name online to NASA, and the space agency will put it on the lander—in super-tiny form, of course—which will set off for Mars in May 2018.

This is the public's second shot at getting their name to Mars: NASA first put out a call for names to go to the Red Planet with InSight in 2015. The planned 2016 launch was delayed over an issue with one of the instruments, and since the naming initiative was so popular—almost 827,000 people submitted their names the first time around—they decided to open the opportunity back up and add a second microchip.

NASA is encouraging people to sign up even if they've sent in their names for other mission microchips. (The space agency also sent 1.38 million names up with Orion's first test flight in 2014.) You can put your name on both of InSight's microchips, in other words, as well as any future missions. The agency's "frequent flyer" program allows you to keep track of every mission to which your name is attached. Interplanetary fame, here you come.

You can submit your name for the InSight mission until November 1 using this form. If you miss the deadline, though, don't worry too much: You'll soon be able to submit your name for Exploration Mission-1's November 2018 launch.
