What Happened To Mars?

What Happened to Mars?

Billions of years ago, Mars was a very different world. Liquid water flowed in long rivers that emptied into lakes and shallow seas. A thick atmosphere blanketed the planet and kept it warm.

Today, Mars is bitter cold. The Red Planet’s thin and wispy atmosphere provides scant cover for the surface below.

Our MAVEN Mission

The Mars Atmosphere and Volatile EvolutioN (MAVEN) mission is part of our Mars Scout program. This spacecraft launched in November 2013, and is exploring the Red Planet’s upper atmosphere, ionosphere and interactions with the sun and solar wind.

The purpose of the MAVEN mission is to determine the state of the upper atmosphere of Mars, the processes that control it and the overall atmospheric loss that is currently occurring. Specifically, MAVEN is exploring the processes through which the top of the Martian atmosphere can be lost to space. Scientists think that this loss could be important in explaining the changes in the climate of Mars that have occurred over the last four billion years.

New Findings

Today, Nov. 5, we will share new details of key science findings from our ongoing exploration of Mars during a news briefing at 2 p.m. EDT. This event will be broadcast live on NASA Television. Have questions? Use #askNASA during the briefing.

3 Ways You Might Be Marginalizing Disabled Asexual People (And What to Do About It)
Have you noticed how disabled and asexual communities can try to distance themselves from each other? This author's experienced this from all sides, and these examples are so common.

Instead of saying “Asexuality isn’t a disability! Asexual people aren’t disabled,” try “Asexuality isn’t a disability by itself, but there are disabled asexual people and their orientations are just as valid as nondisabled asexual people.”

7 Things That Happen When You Go To Space

Told Through Astronaut Scott Kelly’s Tweets

Astronaut Scott Kelly is currently spending a year in space. Most expeditions to the space station last four to six months. By doubling the length of this mission, researchers hope to better understand how the human body reacts and adapts to long-duration spaceflight. During this one-year mission, Kelly is also participating in the Twins Study. While Kelly is in space, his identical twin brother, retired NASA Astronaut Mark Kelly, will participate in a number of comparative genetic studies.

Here are a few things that happen when astronauts go to the space station:

1. Your personal hygiene takes on a different form:

2. Sleeping arrangements might take some getting used to:

3. Internet services will remind you of the 90s:

4. You never have to do laundry:

5. You get to become immersed in a range of different cultures:

6. All of your water is recycled…yes…that means urine too:

7. You get to see the Earth like never before:

If Earth had Saturn’s Rings

From an excellent post by Jason Davis

From Washington, D.C., the rings would only fill a portion of the sky, but appear striking nonetheless. Here, we see them at sunrise.

If Earth Had Saturn’s Rings

From Guatemala, only 14 degrees above the equator, the rings would begin to stretch across the horizon. Their reflected light would make the moon much brighter.

If Earth Had Saturn’s Rings

From Earth’s equator, Saturn’s rings would be viewed edge-on, appearing as a thin, bright line bisecting the sky.

If Earth Had Saturn’s Rings

At the March and September equinoxes, the Sun would be positioned directly over the rings, casting a dramatic shadow at the equator.

If Earth Had Saturn’s Rings

At midnight at the Tropic of Capricorn, which sits at 23 degrees south latitude, the Earth casts a shadow over the middle of the rings, while the outer portions remain lit.
