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.

First-Ever Map of Titan Reveals That Saturn’s Moon Is a Lot Like Earth

If there's any life in this solar system outside Earth, we likely won't find it on Mars or even on another planet. Saturn's moon Titan is the place in our celestial neighborhood that's most similar to our own home, and it's where scientists think we have one of the best chances of discovering life. Now, as Nature reports, newly visualized data shows just how much Titan has in common with Earth.

Between 2004 and 2017, the NASA spacecraft Cassini performed more than 100 fly-bys of Saturn's moon. Titan is unique in that it's the only moon in the solar system with clouds and a dense, weather-forming atmosphere. This has made it hard to study from space, but by flying close to the surface, Cassini was able to capture the landscape in an unprecedented level of detail.

NASA's new map of Titan, published in the journal Nature Astronomy, reveals a varied world of mountains, valleys, plains, and sandy dunes that starkly contrast with the desolate wastelands we've seen on neighboring planets. It's also home to seas and lakes, making it the only place in the solar system other than Earth with known bodies of liquid. But instead of water, the pools mottling the moon's surface consist of liquid methane.

Even with its Earth-like geology and atmosphere, chances of finding life on Titan are still slim: Temperatures on the surface average around -300°F. If life does exist there, it's likely limited to microbes in the moon's craters and icy volcanoes.

It will be a while before NASA is able to study Titan up close again: NASA's next drone mission to the body is set for 2034. Until then, scientists have plenty of data recorded by Cassini to teach them more about how the moon formed and continues to change.

A Rare Unicorn Meteor Outburst Could Be Visible for Less Than an Hour on Thursday

Your chances of seeing a unicorn this week are slim, but if you look up on Thursday night, you may see something that's almost as extraordinary. As Sky & Telescope reports, the upcoming Alpha Monocerotid meteor shower could produce a meteor outburst, which means there could be multiple shooting stars per second streaming from the unicorn constellation.

What is a unicorn meteor shower?

There's nothing particularly magical about the Alpha Monocerotids. They appear to originate near the star Procyon, which is next to the constellation Monoceros, the Greek name for unicorn.

The shower is known for occasionally packing a dense flurry of activity into a brief viewing window. The meteors appear between November 15 through the 25th of each year, and peak around the 22nd. Several times a century, the shower treats sky gazers to an "outburst" of shooting stars that lasts less than an hour.

Such an outburst is predicted for 2019. According to astronomers Peter Jenniskens and Esko Lyytinen, the Earth is on track to pass through a thick portion of the tail of the unknown comet that provides debris for the shower. The conditions are almost the same as they were in 1995, when the Alpha Monocerotids lit up the sky at a rate of 400 meteors per hour, which is approaching meteor storm levels. For that reason, the scientists are expecting shooting stars to appear in the same numbers this time around.

How to see the meteor outburst

Timing is crucial if you want to catch the Alpha Monocerotids, even more than with regular meteor showers. The outburst is expected to start at 11:15 p.m. EST and last just 15 to 40 minutes. Luckily, the sun will be fully set by then and the crescent moon won't rise until after 2 a.m, creating optimal viewing conditions for the eastern half of the country. The shooting stars are fast—traveling at 40 miles per second—and they come at random. Don't be surprised to wait a minute between meteors during some parts of the outburst and less than a second at others.
