Solar System: Top 5 Things to Know This Week

It’s only Tuesday and this week is already filled with news about our solar system. Here are the top five things to know this week:

1) Mars!

With five spacecraft in orbit and two rovers exploring the ground, there’s always something new and interesting about the Red Planet. Yesterday things got even more exciting when we released the most compelling evidence yet that liquid water sometimes flows on Mars today.

2) HTV-5 Cargo Ship

On Monday, the HTV-5 cargo ship was released from the International Space Station to burn up as it reenters Earth’s atmosphere. The HTV-5 carried a variety of experiments and supplies to the space station, and was docked for five weeks.

3) Pluto Continues to Excite

If you haven’t been keeping up with the weekly releases of newly downloaded pictures from our New Horizons spacecraft, you are definitely missing out. But don’t worry, we have you covered. The latest updates can be found HERE, be sure to follow along as new information is released. More images are scheduled to be featured on Oct. 1.

4) Cassini Mission

This week on Sept. 30, our Cassini spacecraft will reach the closest point to Saturn in it’s latest orbit around the planet. Just to put things in perspective, that will be Cassini’s 222nd orbit around Saturn! Learn more about this mission HERE.

5) What Happened to Mars’ Atmosphere?

Believe it or not, the Martian atmosphere we see today used to be much more substantial many years ago. What happened? Our Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft has been in orbit around Mars for one Earth year, searching for the answers. Learn more HERE.

NASA in the 1970s expected to process the Space Shuttle after flights quickly, like an airliner. It didn’t work out that way.

The Key to Colonizing Mars Could Be These Tiny Green Microbes

Long ago, a clan of hardy microbes called cyanobacteria helped terraform the lifeless Earth into a vibrant biosphere. Today, the very same critters could be the key to colonizing Mars.

Plants are going to have a tough time on the Red Planet’s hostile surface, but cyanobacteria have coped with extreme environments for eons. A paper led by astrobiologist Lynn Rothschild of NASA’s Ames Research Institute argues that we can harness these tiny photosynthesis machines to produce many of the resources we’ll need to survive, from food and oxygen to metals and medicine. Here are all the ways cyanobacteria can help us build a Martian colony.
