Down to Earth

The California Senate has voted to replace one of their statues in Statuary Hall in Washington, D.C. with a likeness of late astronaut Sally Ride. Awesome! The bill still has a few legislative hurdles before it is law though.

The user-proposed LEGO model of the ISS has received enough votes for the company to move it to “production review”.

United Launch Alliance announced their plans for their Next Generation Launch System (NGLS) which will replace the Atlas family of rockets in a few short years (hopefully). The new rocket will be named Vulcan and will be ULA’s answer to the US Congress’s order to stop using the Russian built RD-180 engine to launch DoD assets. Not only does Vulcan solve the RD-180 problem by contracting with Blue Origin to develop a new liquid propellant first stage, the BE-4, but it answers SpaceX’s innovative attempts at reusability with their own system (see graphic below).

Sierra Nevada Corporation and the Germany space agency DLR signed an agreement to cooperate on future uses of the Dream Chaser space plane.

In Orbit

SpaceX launched CRS-6, another ISS resupply mission, last Tuesday. The cargo arrived safely on Friday when Samantha Cristoforetti captured the vehicle with the Canadarm-2.

The Dragon spacecraft has a new ISSpresso machine onboard, built by an Italian company to be delivered while Samantha Cristoforetti is on ISS.

SpaceX’s attempt to land their Falcon 9 rocket’s first stage on a barge (ahem, the Autonomous Spaceport Droneship) was not successful. Luckily, we got what we were all waiting for: awesome footage of the not-landing! Good job, SpaceX! They will likely stick it next time (YouTube link via Parabolic Arc).

Some SpaceX employees had some fun (honestly, I don’t know how they found the time) producing a music video parody of Uptown Funk entitled Launch You Up. Enjoy. (Update: I’ve been informed that these are not actually SpaceX employees. The video is by Cinesaurus which is in the business of producing parodies on YouTube. It is entertaining nevertheless)

Those guys better get back to work. The next Falcon 9 launch is scheduled for April 27, which would be the fastest time between two Falcon 9 launches, 10 days, beating the previous record of 13 days.

This Hyundai commercial entitled “A Message To Space” may be an ad, but it is still inspirational and I love seeing the ISS on TV. I hope to see more things like this in the future!

And here’s the obligatory list of best pictures taken from the ISS astronauts over the last week. They never fail to impress:

Around the Solar System

Measurements from the Curiosity rover indicate that liquid water could exist in the soil at night on Mars. In short, the speculated process requires two key factors: salts in the soil, and then humid air during the day that freezes into frost in the evening. This frost then combines with the salts to make a brine which has a higher freezing point, such that it might melt and exist as liquid. Exciting!

Curiosity also stopped to watch a sunset on Sol 956 last week in order to catch images of a Mercury transit. As far as I have found, the images have not been released yet.

Meanwhile, Dawn is getting closer to Ceres and New Horizons is getting closer to Pluto. Both probes returned some exciting new imagery over the last week, including the first color view of Pluto and Charon from New Horizons.

I just learned about the small probe PROCYON that is heading towards asteroid 2000 DP107. PROCYON was launched as a secondary payload with Japan’s Hayabusa-2. Unfortunately, PROCYON is having a bit of a problem with its ion propulsion. I hope they get it fixed soon!
