Sun Facts

Posted on March 12, 2019 by richardficek

The Sun is the star at the center of the Solar System and is a nearly perfect sphere of hot plasma. Its diameter is about 1.39 million kilometers (864,000 miles) – 109 times that of Earth – and its mass is about 330,000 times that of Earth. The Sun accounts for about 99.86% of the total mass of the Solar System and its … Continue reading Sun Facts → Continue reading →

Economics of Intra-Stellar Spacecraft

Posted on March 12, 2019 by Andrew Talley

After seeing the discussion of spacecraft within our solar system in the textbook, and the impact the mission type has on the cost, I was curious to see how these discussions were reflected in actual data on these missions. So, I copied each mission from the book into Excel, and then researched each. Thanks mostly … Continue reading Economics of Intra-Stellar Spacecraft → Continue reading →

Composition of Solar System

Posted on March 12, 2019 by Yihao Yan

The solar system is a planetary system consisted of star Sun, planets, comets and other objects orbiting around the Sun, and Earth is one of them. The major mass of solar system is from the Sun. The sun is a G2 main-sequence star at the center of solar system which contains about 99.86% of total … Continue reading Composition of Solar System → Continue reading →

Exploration and Geology of Mercury

Posted on March 12, 2019 by jordyn27

Because it is so technically difficult to reach Mercury with spacecraft’s from Earth, the geology of Mercury is understood the least of all the terrestrial worlds. The main reason it is so hard to reach is due to how close Mercury is to the Sun.  When a spacecraft moves down Sun’s gravitational potential well to … Continue reading Exploration and Geology of Mercury → Continue reading →

The 1 Shocking Discovery NASA Doesn’t Want You To Know…

Posted on March 12, 2019 by josiahgray12

  VectorStock For most, the discoveries of NASA are taken at face value and seen as trustworthy. However, for a growing number of conspiracists, alternative facts are rising into prevalence. I would like to introduce one of these alternative facts in this blog post. Although it may seem unbelievable, hopefully after a proper explanation, you … Continue reading The 1 Shocking Discovery NASA Doesn’t Want You To Know… → Continue reading →

Gravity and Sun Size

Posted on March 12, 2019 by JSpin

Gravity as the Driving Force The Sun has a mass of 2 * 10^30 kg. Gravity exerts a compression force on the Sun proportional to this immense mass. So why doesn’t the sun collapse under the weight of its gravity? The pressure of the center of the Sun is about 340 billion times the air … Continue reading Gravity and Sun Size → Continue reading →

Nuclear Fusion in the Sun

Posted on March 11, 2019 by richardtli

Nuclear fusion is the process in which the Sun and all other stars generate energy through the combination of light atoms into heavier ones. The nuclear fusion in most stars is carried out in proton-proton fusion. In the first step, two protons fused together to create a proton-neutron core and emitting a neutrino and positron. … Continue reading Nuclear Fusion in the Sun → Continue reading →

An Artificial Sun

Posted on March 11, 2019 by Campbell Flower

In November of 2018, Chinese scientists announced their work on an artificial sun. Their goal is to develop the same nuclear fusion process that occurs within the sun (the conversion of hydrogen into helium) on Earth to ultimately create a source of unlimited clean energy. One of the biggest challenges of this project is to … Continue reading An Artificial Sun → Continue reading →

Finding Nuclear Fusion

Posted on March 11, 2019 by Aaron Molotsky

Before the advent of Modern Science and its ability to explain natural phenomena relatively well, we had no idea how the Sun actually worked. Scientists had no idea that the Sun was just a giant ball of really hot gas that’s able to generate light using its own mass. However, over the course of time … Continue reading Finding Nuclear Fusion → Continue reading →

Retrieving Voyager 1 – A Rescue Mission

Posted on March 11, 2019 by Jonathan Roberts

In 1977, NASA launched Voyager 1 to study the far reaches of our solar system. The program was a tremendous success: not only did the probe gather useful information about Jupiter and Saturn, it also captured the first detailed images of their moons (including a flyby of Titan, Saturn’s largest moon). Even now, after Voyager … Continue reading Retrieving Voyager 1 – A Rescue Mission → Continue reading →
