Identical Twin U.S. Astronauts to Serve as Research Subjects


NASA hired identical twins to conduct an experiment to investigate the "genetic impacts of long-
duration spaceflight."

Astronaut Mark Kelly is staying on Earth to be the informational base of the experiment while his identical twin, Scott Kelly, is being the informational base during orbit.

Scott “is preparing for a year-long mission aboard the International Space Station, the longest single spaceflight NASA has ever attempted.” He has been veteran in two shuttle missions and has been a crew member at the space station and commander too.

Mark lives in Arizona with his wife but is willing to travel as much as needed to Houston to conduct the experiment. He left his work at NASA in 2011 to take care of his wife (Gabrielle Giffords, who is a former U.S. Representative) who was shot through the head in January of 2011 at a political event in Arizona in which a gunman left six people killed and 26 wounded.

Scientists will investigate the differences between the twins while one is in a gravity-free environment and the other one is in Earth.

The yearlong spaceflight is set to launch in March of 2015. The twins will have just turned 50.

Safety and Chemistry Class

Science is one of my favorite subjects even though sometimes I find it hard to understand depending on the lesson learned. One of my favorite things about science is getting to do experiments since its a fun way to learn. This year I'll make sure to bring all my homework in time and pay attention so that I don't get lost and get bad grades on the test.
Safety is one of the most important things to keep in mind in science class, especially chemistry because of the dangerous chemicals. Some safety rules to keep in mind are:
1. Inform the instructor in case of an emergency.
2. Girls should wear a ponytail.
3. Wear goggles and an apron AT ALL TIMES WHILE IN THE LAB AREA
4. No horseplay
5. No food or drink
These are just some of the important rules to follow. If you follow them, it is less probable that there is an accident.

Kepler Spacecraft Disabled

In 2009, NASA sent a spacecraft called Kepler which it's primary goal was "...to determine the frequency of Earth-like planets that orbit stars similar to our sun in one selected area of the Milky Way, and by extension throughout the universe." In a few years Kepler detected 135 planets and more tan 3,500 candidate planets. No planets that have all the "habitable" resources we need have been discovered yet, and Kepler was the closest we had to discovering one. However, in May of 2013, Kepler stopped working properly and since that day NASA has been trying to fix it but has been unsuccessful in completing the mission. There is no way Kepler will be able to fulfill its determined purpose again but NASA is now trying to figure out if there is another way Kepler and the telescope could be used for research. Many other uses for Kepler have been proposed since the problem was first identified. Some other purposes include studying asteroids, comets, supernovae and some large planets in our galaxy.
William Borucki, Kepler's science principal investigator said "While the mission to collected information about planets that orbit a small slice of the Milky Way will now end, analysis of the data collected so far will go on for three or four years, and great results are anticipated." He also said how the Kepler investigation isn't over yet, and how they are expecting great and exciting new discoveries in the following years to come.
NASA giving up trying to fix Kepler will provide a new opportunity for more scientific discoveries since NASA is currently building TESS or Transiting Exoplanet Survey Satellite. TESS is planned to be launched in 2017.
