Over the weekend, NASA teased some very big news.
More specifically, all weekend long, the agency teased that a major Mars mystery was solved.
This morning's press conference, broadcast live from NASA headquarters in Washington, D.C., on NASA Television and on the agency's website, did not disappoint.

At 11:30 a.m. Sept. 28, 2015, NASA announced that, for the first time, they have evidence of flowing water on Mars.
They're called Recurring Slope Lineae, or RSL. They appear as dark streaks that begin in late spring, grow in the summer, and disappear by fall. Until now, NASA researchers couldn't explain what the streaks were.
Turns out, the streaks are evidence of salty water intermittently moving across the surface of the planet.

But this isn't the first time water's been found on Mars.
(Wait, what?) Yep. Researchers discovered water frozen in small, salty puddles on the planet's surface at night and permafrost at Mars' poles.

But this latest announcement and discovery marks the first time that flowing water has been found on the incredibly cold, harsh planet.
Evidence of moving water could be a huge step forward in the search for life, and it opens up possibilities when it comes to the red planet's ability to sustain human life.
So ... are we sending humans to Mars? Not just yet.

Even with the discovery of moving water, inhabiting the red planet — or even sending humans for a visit — is still a long way off. (Sorry, Matt Damon).
So for now, NASA and other international space agencies are conducting dry runs here on Earth.
Last October, six strangers (three men and three women) were picked to live in a dome on a Hawaiian volcano for eight months to simulate a stay on Mars. NASA backed the study to see if people isolated from civilization can work together and get along. It was essentially "Real World: Red Planet."
Even with successful simulations, NASA estimates the first human-manned mission to Mars won't happen until the 2030s.
That may seem like a long time to wait, especially after today's announcement. But as Dr. Jim Green, director of planetary science at NASA, told the crowd at today's announcement, it's all about safety.
"NASA's approach to exploration is not 'Star Trek.' It's not 'go where no man has gone before,'" he said. "It's really a very methodical approach for which we learn everything about the environment that we're going to subject humans to that we possibly can. ... And I anticipate continuing to do that for many years before humans even get in the vicinity of Mars."
But! This is a major breakthrough, and it lays the groundwork for many missions to come.
While you can't drink the water on Mars (it's much too salty) and you can't grow crops with it (the atmosphere on Mars is too thin), finding moving water on Mars is truly unprecedented and opens a lot of doors for exciting missions and exploration to come.
As astronaut John Grunsfeld said at this morning's announcement, "We are on a journey to Mars, and science is leading the way."

12 non-threatening leadership strategies for women
We mustn't hurt a man's feelings.
Men and the feels.
Note: This an excerpt is from Sarah Cooper's book, How to Be Successful Without Hurting Men's Feelings.
In this fast-paced business world, female leaders need to make sure they're not perceived as pushy, aggressive, or competent.
One way to do that is to alter your leadership style to account for the fragile male ego.
Should men accept powerful women and not feel threatened by them? Yes. Is that asking too much?
IS IT?
Sorry, I didn't mean to get aggressive there. Anyhoo, here are twelve non-threatening leadership strategies for women.
Encourage.

When setting a deadline, ask your coworker what he thinks of doing something, instead of just asking him to get it done. This makes him feel less like you're telling him what to do and more like you care about his opinions.
Sharing ideas.
With permission from Sarah Cooper.
When sharing your ideas, overconfidence is a killer. You don't want your male coworkers to think you're getting all uppity. Instead, downplay your ideas as just "thinking out loud," "throwing something out there," or sharing something "dumb," "random," or "crazy."
Email requests.

Pepper your emails with exclamation marks and emojis so you don't come across as too clear or direct. Your lack of efficient communication will make you seem more approachable.
Idea sharing.
With permission from Sarah Cooper.
If a male coworker steals your idea in a meeting, thank him for it. Give him kudos for how he explained your idea so clearly. And let's face it, no one might've ever heard it if he hadn't repeated it.
Sexism.
With permission from Sarah Cooper.
When you hear a sexist comment, the awkward laugh is key. Practice your awkward laugh at home, with your friends and family, and in the mirror. Make sure you sound truly delighted even as your soul is dying inside.
Mansplain.

Men love explaining things. But when he's explaining something and you already know that, it might be tempting to say, "I already know that." Instead, have him explain it to you over and over again. It will make him feel useful and will give you some time to think about how to avoid him in the future.
Mistakes.
With permission from Sarah Cooper.
Pointing out a mistake is always risky so it's important to always apologize for noticing the mistake and then make sure that no one thinks you're too sure about it. People will appreciate your "hey what do I know?!" sensibilities.
Promotions.
With permission from Sarah Cooper.
Asking your manager for a promotion could make you seem power- hungry, opportunistic, and transparent. Instead, ask a male coworker to vouch for you. Have your coworker tell your manager you'd be great for the role even though you don't really want it. This will make you more likely to actually get that promotion.
Rude.
With permission from Sarah Cooper.
Sometimes not everyone is properly introduced at the start of a meeting. Don't take it personally even if it happens to you all the time, and certainly don't stop the meeting from moving forward to introduce yourself. Sending a quick note afterward is the best way to introduce yourself without seeming too self-important.
Interruptions.
With permission from Sarah Cooper.
When you get interrupted, you might be tempted to just continue talking or even ask if you can finish what you were saying. This is treacherous territory. Instead, simply stop talking. The path of least resistance is silence.
Collaboration.
With permission from Sarah Cooper.
When collaborating with a man, type using only one finger. Skill and speed are very off-putting.
Disagreements.
With permission from Sarah Cooper.
When all else fails, wear a mustache so everyone sees you as more man-like. This will cancel out any need to change your leadership style. In fact, you may even get a quick promotion!
In conclusion...
With permission from Sarah Cooper.
Many women have discovered the secret power of non-threatening leadership. We call it a "secret power" because no one else actually knows about it. We keep our power hidden within ourselves so that it doesn't frighten and intimidate others. That's what makes us the true unsung heroes of the corporate world.
