Strange Behavior of the Sun's Iron Heart Surprises Scientists

Their is a machine(Z machine) on earth that is capable of creating temperatures that are similar to what is found inside the sun's heart and scientists have been using this to see how iron reacts at those kinds of temperatures and the results are astounding. The Z machine creates a pulse of X-rays contains 80 trillion watts of electricity but only last for 100 nanoseconds. When Bailey did this to a small amount of iron they saw that it turned to plasma like in the sun but that they underestimated the opacity of iron by 7 percent.This finding might affect the study of the sun and other stars because they have never tested the opacity of oxygen, iron, and carbon before so it could prove to why they have gotten the results they have and why there are so many conflicts between the calculations and observational data. Knowing the opacity of these three elements might prove that they don't have to change anything and that previous models might still be correct. Right know Bailey is trying to determine why they predicted such a low opacity for the elements. It amazes me sometimes what technology can accomplish like creating specks of solar matter for our observation and with further advances in technology we will be able to better understand the sun and similar stars.

Is Moon Mining Economically Feasible?

Ian Crawford, a professor of planetary science and astrobiology at Birkbeck College, London has made an assessment of whether or not the mining the moon would be economically feasible. One of the points he makes is that strip-mining the resource helium-3 would be that it is a fossil fuel so once it's used up there is no more and that instead of trying to find ways of using that for power we should use it instead to find a renewable resource that would better for us in the long run. He also points that we should know exactly how much water there is inside the moon before planning accordingly. Not to mention the possibility of rare elements that are scarce on earth being found in abundance in the moon or from left over asteroids that have hit it during its existence. While mining the moon might give us resources we still have to think of the consequences if we go through with this. The moon has protected us from asteroids and meteor for ages and if we were to mine it we would decrease its size and stability which cause it to break or explode if another asteroid were to hit which could become detrimental to us. While mining the moon wouldn't be a bad thing we should see all the problems that it might cause in the future.

Private Dream Chaser Space Plane Keeps Marching Toward Flight

The Dream Chaser space plane continues to make closer steps towards flight even though it wasn't chosen by NASA to ferry astronauts to and from the International Space Station. Sierra Nevada Corporation recently checked off a milestone laid out in the company's last commercial-crew contract with NASA, which was signed in 2012 even though they weren't funded for the final phase of the project while NASA gave the funding to SpaceX and Boeing to provide astronaut taxis. They recently just passed milestone 15a which validates their performance and safety, while decreasing the risk for this critical propulsion system. The goal of the Commercial Crew Program is to restart launches of astronauts from U.S. soil, a practice which was suspended in 2011 when the space shuttle retired. Current International Space Station crews launch with Russian Soyuz spacecraft, which leaves Earth from Kazakhstan. It is inspiring to see the Sierra Nevada is still making progress towards their goal even though they haven't received the funding from NASA. Also, they filed a protest to the GAO, which was denied, concerning the award of CCtCap.

Telescope Captures Stunning Images of Alien Planets and Young Star

The Gemini Planet Imager (GPI) has already found unexpected differences between two sister exoplanets and helped to characterize the ring of dust and rocky bodies surrounding a young star even though it hasn't been doing full science operations until this past November. GPI was able to identify differences in the light emitted by the two sister planets which is astonishing because both of the planets are similar in size and appear to be the same color although scientists believe that this is the case because their are differences in cloud cover between the two. GPI was built to characterize and find gas giants but it isn't able to identify small rock planets but scientist believe that the data they get from it might help to build future gear that will be able to do just that. It is amazing that we have come so far in such a short time when it concerns our knowledge of the cosmos it makes me giddy in anticipation to see what else is in store in the future.

Spectacular Time-Lapse Video Shows Earth Through an Astronaut's Eyes

This video shows us what a astronaut sees outside of their space station while looking at earth. It is amazing to think of the sights that they must see while up there and how their whole perspective about things changes when they are on the outside looking in so to speak. This video was made from connecting over 12,000 pictures taken by Astronaut Alexander Gerst and giving the effect that it was taken continuously over a period of time instead of individual pictures strong together. This video really captures the beauty of space and of how our earth looks like from the outside and makes you feel a little envious of the experience and sights that these astronauts must experience.

Early yesterday morning SpaceX launched the Dragon cargo ship into space heading towards the international space station. Not all was successful because Falcon 9's rocket first stage was destroyed upon landing on its target in the Atlantic ocean. SpaceX was trying to land the rocket safely to make further progress in their quest for reusable rocket technology. The scientists aren't that disappointed because their weren't actually expecting it to succeed but they are going to use the data that they collected to make further progress on the landing technology of the rockets.

The main point of the launch was actually the launch of the cargo ship which will be landing in the space station some time tomorrow. While the rocket landing might have been a failure the main objective of the launch was a success and will give them more information for their next attempt. After delivering the cargo the Dragon will be returning to earth in a months time and landing in the Atlantic ocean. This is special because the dragon is the only cargo vehicle that has returned to earth because the others burn up in reentry.

SpaceX Postpones Cargo Launch, Daring Rocket Test to Saturday

SpaceX delayed its next robotic cargo launch toward the International Space Station — which also featured a bold rocket-reusability test — by another day, to early yesterday morning. The launch was supposed to happen Tuesday but was stopped before liftoff because of an issue with an actuator on the Falcon 9's second stage. The primary objective of the launch was to send the unmanned Dragon — which is loaded with more than 5,000 pounds of food, scientific experiments and spare parts — on its way to the orbiting lab. But SpaceX will also try to bring the Falcon 9's first stage back to Earth for a pinpoint landing on a floating platform in the Atlantic Ocean. This is a bold move for them to try to include both a delivery and a experiment in one but if it is successful it will be a great stride in reusable rocket technology which will overall decrease the cost of rockets by a lot if they won't have to keep building the rockets but only having to refuel them. We will learn the success of this experiment in a month when the ship comes to earth.
