Elon Musk to launch 4425 satellites for global internet

Anthony Garreffa | Mon, Nov 21 2016 1:01 AM CST

Elon Musk is getting closer to being the real life Tony Stark, with his private rocket launch service SpaceX requesting permission from the government to launch a "massive satellite network that would provide high-speed, global internet coverage", reports Reuters.

SpaceX would eventually launch 4425 satellites, with Musk predicting it would cost at least $10 billion, and that was nearly two years ago when he first announced the project in January 2015. The latest details on the project include technical detailed of the proposed network, but there isn't a mention of the costs involved.

The financial backers of SpaceX include Alphabet's Google Inc and Fidelity Investments, who have pumped over $1 billion into Elon Musk's space company. SpaceX will launch around 800 satellites at first, which will cover the United Spaces, Puerto Rico, and the US Virgin Islands. SpaceX said in technical documents that it filed to the government: "The system is designed to provide a wide range of broadband and communications services for residential, commercial, institutional, government and professional users worldwide".

SpaceX will launch their satellites into orbits ranging from 714 miles to 823 miles, or 1150-1325 km above the Earth, with each satellite at the size of an average car. The satellites will be solar-powered, and weigh 850 pounds (386 kg).

The Soyuz spacecraft carrying Peggy Whitson of NASA, Oleg Novitskiy of Roscosmos and Thomas Pesquet of ESA (European Space Agency), is scheduled to dock with the Space Station's Rassvet module on Saturday, November 19th.

The crew will be welcomed by astronaut Shane Kimbrough and cosmonauts Sergey Ryzhikov and Andrey Borisenko, who arrived at the Station a month ago.

The biggest Supermoon in decades appears tonight

Lana Jelic | Sun, Nov 13 2016 1:35 PM CST

Tonight, the night of November 14th we'll get to witness a spectacular sight in our sky - the Supermoon. The full Moon of November 14th is not only the closest full Moon of 2016 but also the closest full Moon to date in the 21st century. The full Moon won't come this close to Earth again until November 25, 2034. The last time the full Moon was this close to Earth was in 1948.

NASA explained this phenomenon.

The Moon's orbit around Earth is slightly elliptical, so sometimes it is closer, and sometimes it's farther away. When the Moon is full as it makes its closest pass to Earth it is known as a Supermoon. At perigee - the point at which the Moon is closest to Earth - the Moon can be as much as 14 percent closer to Earth than at apogee when the Moon is farthest from our planet. The full Moon appears that much larger in diameter and because it is larger shines 30 percent more moonlight onto the Earth.

The biggest and brightest Moon for observers in the United States will be on Monday morning just before dawn.

SpaceX has solved the mystery of Falcon 9's explosion

Lana Jelic | Mon, Nov 7 2016 9:23 AM CST

Elon Musk thinks they have finally solved the mystery of their September's Falcon 9 explosion. Speaking with CNBC, he stated that the explosion was caused by a "really surprising problem that's never been encountered before in the history of rocketry."

Just last week, Musk said that the cause of the explosion is one of the toughest puzzles the company has ever had to solve.

The explosion caused complications for NASA since SpaceX was supposed to transfer cargo to International Space Station. However, Orbital ATK stepped in and performed their first successful launch since October 2014 when the rocket failed, and the vehicle and payload were destroyed causing $15 million in damage.

Musk now believes they have found the cause of the accident which he claims is "a combination of liquid helium, advanced carbon fiber composites, and solid oxygen."

Vote while you float: This is how astronauts vote

Lana Jelic | Fri, Nov 4 2016 6:11 PM CDT

The United States presidential election of 2016 is scheduled for Tuesday, November 8th, 2016. The astronauts aboard the International Space Station also have the ability to vote from space thanks to a bill passed by the Texas legislature in 1997.

Vote while you float: This is how astronauts vote | TweakTown.com

For astronauts, the voting process starts a year before launch, when astronauts can select which elections (local/state/federal) that they want to participate in while in space. Then, six months before the election, astronauts are provided with a standard form: the "Voter Registration and Absentee Ballot Request - Federal Post Card Application."

Voting in space was first used the same year it was implemented, in 1997. NASA's astronaut David Wolf became the first American to vote from space, casting a ballot in a 1997 local election. At the time, he was aboard the Russian Mir Space Station.

Closest Supermoon in 68 years rocks the sky this month

Lana Jelic | Wed, Nov 2 2016 4:27 PM CDT

Fans of astronomy should prepare for November 14th when they'll have the opportunity to enjoy a rare Supermoon.

Closest Supermoon in 68 years rocks the sky this month | TweakTown.com

The full Moon of November 14th is not only the closest full Moon of 2016 but also the closest full Moon to date in the 21st century. The full Moon won't come this close to Earth again until November 25, 2034. The last time the full Moon was this close to Earth was in 1948.

Since the moon's orbit is elliptical, one side (perigee) is about 30,000 miles closer to Earth than the other (apogee). The word syzygy, in addition to being useful in word games, is the scientific name for when the Earth, Sun, and Moon line up as the Moon orbits Earth. When perigee-syzygy of the Earth-moon-sun system occurs and the Moon is on the opposite side of the Earth from the Sun, we get a perigee Moon or more commonly, a Supermoon!

Humans mark 16 years of constant presence in space

Lana Jelic | Wed, Nov 2 2016 2:28 PM CDT

The International Space Station has been continuously inhabited for 5,844 days since Expedition 1's crew of three arrived there on this day in 2000.

Expedition 1 consisted of an astronaut Bill Shepherd and two cosmonauts Yuri Gidzenko and Sergei K. Krikalev. They arrived at the Space Station on November 2nd, 2000, 16 years ago. It was the beginning of an uninterrupted human presence on the Station which continues to this day. The trio spent 136 days aboard the Station.

The assembly of the International Space Station, a major endeavor in space architecture, began in November 1998. The modules were all assembled in space, and it took 13 years to finish the Station. Five different space agencies participated in its construction. The European Space Agency later said that the costs of development, assembly and maintenance of the Station in ten years had been around $110 billion, but the actual cost is probably much higher.

The entire documentary talks about the fossil fuel industry and the effect it has on our planet, explains the devastating consequences, and tries to find a solution for inevitable climate change, who's effects we are already witnessing.

Elon Musk appears in the documentary (he also appeared in Racing Extinction, which you should watch if you haven't already) and leads DiCaprio trough Tesla's Gigafactory in Nevada.

Musk explains that the Gigafactory isn't built just to manufacture lithium-ion batteries, but he hopes is will serve as a template for how others could contribute to converting the world to clean energy.
