In this instructable, I will teach you how to fold the plain awesome origami F-16! This model is not nearly as hard to fold as it looks, so don’t be deterred by its complex appearance.
Despite the sad fact that this particular plane doesn’t fly too well, it never fails to impress. If you want to see my youtube video on how to make this same model, just click How To Fold an Origami F-16 to see a tutorial that is slightly easier to follow. So lets get started!
My printer paper is standard 8.5×11 inch. Fold it in half lengthwise, or hotdog style as some people call it, then unfold….(more)
The crew of Apollo 1 were the first fatalities in America’s space programme, but they will forever be remembered as pioneers of manned space exploration.
Gemma Lavender writes: Following the success of the Mercury and Gemini missions in the 1960’s, NASA set about planning a series of manned missions to the Moon that would become known as the Apollo missions, under direction of John F. Kennedy to land a man on the moon by 1970. Apollo 1 was to be the first manned mission and, although it would not travel to the moon itself, it was intended to test important technologies in Earth orbit with Virgil “Gus” Grissom, Edward White and Roger Chaffee on board. Tragically, however, the spacecraft was destroyed in a cabin fire during a launch pad test 47 years ago on 27 January 1967.
Each of the three astronauts had been influential during NASA’s space exploration program in the run-up to Apollo 1. Gus Grissom was the second American in space aboard Liberty Bell 7, the second Project Mercury flight, in 1961. He later became the first American to fly in space twice, piloting the Gemini 3 spacecraft in orbit in 1965.
Edward White was the first American to walk in space during the Gemini 4 spaceflight, also in 1965, when he spent 36 minutes outside the spacecraft. Roger Chaffee was the only one of the three who had not flown in space before. He was chosen in NASA’s third pool of astronauts in 1963 and served as capsule communicator on the ground alongside Grissom for White’s Gemini 4 mission. Read the rest of this entry »
The metal balls fell from the sky, scaring local residents.
Vietnam’s military is investigating the appearance of three mysterious metal balls — believed to be debris from space — which landed in the country’s remote north, a senior army official said Friday.
Two metal balls were discovered in northwestern Yen Bai province on January 2, army spokesman Lieutenant General Vo Van Tuan told AFP.
Later a larger ball weighing some 45 kilograms (100 pounds) landed in a maize field in neighbouring Tuyen Quang province, he said.
“We are still identifying where they came from,” he said, adding the army had determined they did not contain explosives or hazardous material.
The metal balls fell from the sky, he said, scaring local residents.
“Before and after these objects were discovered, the Vietnamese army was not conducting any military activity in the region,” Tuan said.
Charles Krauthammer writes: Fractured and divided as we are, on one thing we can agree: 2015 was a miserable year. The only cheer was provided by Lincoln Chafee and the Pluto flyby (two separate phenomena), as well as one seminal aeronautical breakthrough.
On Dec. 21, Elon Musk’s SpaceX, after launching 11 satellites into orbit, returned its 15-story booster rocket, upright and intact, to a landing pad at Cape Canaveral. That’s a $60 million mountain of machinery — recovered. (The traditional booster rocket either burns up or disappears into some ocean.)
The reusable rocket has arrived. Arguably, it arrived a month earlier when Blue Origin, a privately owned outfit created by Jeffrey P. Bezos (Amazon chief executive and owner of this newspaper) launched and landed its own booster rocket, albeit for a suborbital flight. But whether you attribute priority to Musk or Bezos, the two events together mark the inauguration of a new era in spaceflight.
Musk predicts that the reusable rocket will reduce the cost of accessing space a hundredfold. This depends, of course, on whether the wear and tear and stresses of the launch make the refurbishing prohibitively expensive. Assuming it’s not, and assuming Musk is even 10 percent right, reusability revolutionizes the economics of spaceflight.
Which both democratizes and commercializes it. Which means space travel has now slipped the surly bonds of government — presidents, Congress, NASA bureaucracies. Its future will now be driven far more by a competitive marketplace with its multiplicity of independent actors, including deeply motivated, financially savvy and visionary entrepreneurs.

“Something was going right. Something made us proud.’
J. Christian Adams writes: During Christmastime in 1968, one of the most significant events in human history occurred. The flight of Apollo 8 marked the first time humans departed Earth orbit and traveled to the dark side of the moon. The Christmas Eve lunar orbit of Apollo 8 also marked one of most profoundly unifying moments for our nation. The journey to space was on everyone’s mind Christmas morning. And the fulfillment of man’s most ancient dream was illuminated by man’s most ancient text, while the entire world watched in wonder.
“Never before had man so vividly understood how good and perfectly designed for human life Earth was. Never before had creation been described by men so competent to describe it.”
With the eventual landing of Apollo 11 on the surface of the moon, the achievement of Apollo 8 was nudged into the background. School textbooks teach about Apollo 11, but not Apollo 8. Yet the lunar landing of Apollo 11 merely capped off the journey of Apollo 8. As the world watched on live television, Frank Borman, Jim Lovell, and William Anders departed Earth orbit for space and orbited the moon for the first time.
Perhaps only the circumnavigation of Magellan in 1522 can compare to Apollo 8, and Magellan himself died halfway around the globe. It had a fraction of the significance and risk of Apollo 8. Centuries of experience animated any 16th century sea voyage. When Frank Borman and his crew ignited a single engine burn to leave Earth orbit, they were in a fragile capsule only 12 feet in diameter crossing the cold dangerous expanse of space. Simply, Apollo 8 may be the most significant event in the history of human exploration.
Not only were Borman and his crew the first to depart Earth orbit, they still hold the record for the highest altitude flight. Because of the type of lunar orbit Apollo 8 deployed, they ventured further from Earth than any subsequent manned craft. They were also the first humans to gaze on the totality of the entire Earth. Just imagine their awe.
The awe of the beautiful and distant Earth was captured in Apollo 8’s famous photo of Earthrise over the lunar horizon. In contrast, the surface of the moon below appeared terrifying, bleak, and lifeless to the astronauts – an Earth before creation.
The largest television audience in American history watched the live lunar images from Apollo 8 on Christmas Eve 1968. This was one of those shared experiences so common in our nation’s past, but so rare in our modern world of fractured information and culture. Few unifying events as joyous as Apollo 8 would follow and we are worse off from the loss.
Something else extraordinary happened that Christmas Eve. As our nation gathered around Christmas trees and bulky televisions beaming close-up video of the moon, the three astronauts took turns speaking to the world.
William Anders started.
“For all the people on Earth the crew of Apollo 8 has a message we would like to send you: In the beginning God created the heaven and the earth. And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters. And God said, Let there be light: and there was light. And God saw the light, that it was good: and God divided the light from the darkness.”
Jim Lovell continued, reading the first book of Genesis:
“And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day. And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters. And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so. And God called the firmament Heaven. And the evening and the morning were the second day.”
Then Frank Borman:
“And God said, Let the waters under the heavens be gathered together unto one place, and let the dry land appear: and it was so. And God called the dry land Earth; and the gathering together of the waters called the Seas: and God saw that it was good.”
“And from the crew of Apollo 8, we close with good night, good luck, a Merry Christmas, and God bless all of you — all of you on the good Earth.”
Never before had man so vividly understood how good and perfectly designed for human life Earth was. Never before had creation been described by men so competent to describe it. Read the rest of this entry »
SpaceX Falcon rocket blasts off, booster lands safely
CAPE CANAVERAL, Fla. — Christian Davenport reports: Elon Musk’s SpaceX successfully landed the first stage of its Falcon 9 rocket at its landing pad here Monday evening in its first flight since its rocket exploded six months ago.
The historic landing, the first time a rocket launched a payload into orbit and then returned safely to Earth, was cheered as a sign that SpaceX, the darling of the commercial space industry, has its momentum back.

“The Falcon has landed,” a SpaceX commentator said on the live webcast, as workers at its headquarters went wild, chanting “USA! USA!”
Monday’s flight, initially delayed because of technical concerns, was the second time in a month that a billionaire-backed venture launched a rocket to space and recovered it. And it represents yet another significant step forward in the quest to open up the cosmos to the masses.
In a call with reporters, Musk said that it appeared the stage landed “dead center on the landing pad. … We could not have asked for a better mission.” He called it a “revolutionary moment.”
Typically, rocket boosters are used once, burning up or crashing into the ocean after liftoff. But Musk, the billionaire co-founder of PayPal and Tesla, and Jeffrey P. Bezos, the founder of Amazon.com who has his own space company, have been working on creating reusable rockets that land vertically by using their engine thrust. If they are able to recover rockets and fly them again and again, it would dramatically lower the cost of space flight.
Reusing the first stage, which houses the engine and is the most expensive part of the rocket, was thought impossible by many just a few years ago. But last month Bezos’s Blue Origin flew a rocket to the edge of space, and landed it in a remote swath of West Texas. (Bezos owns The Washington Post.)
On Monday, SpaceX’s first flight since its Falcon 9 rocket blew up in June, Musk topped his fellow tech billionaire and space rival, by landing a larger, more powerful rocket designed to send payloads to orbit, and not just past the boundary of what’s considered space. It was a much more complicated feat that was celebrated as another leap forward for Musk and his merry band of rocketeers.
SpaceX’s unmanned — and recently upgraded — Falcon 9 rocket launched from Cape Canaveral at 8:29 p.m. on a mission to deliver 11 commercial satellites into space for Orbcomm, a communications company. A few minutes later, the second stage separated and headed further on while the towering booster performed an aerial U-turn and headed back to Earth, hurtling back through gusty winds and using its engine thrust to slow down.

LONDON — Jeff Foust reports: A U.S. National Oceanic and Atmospheric Administration satellite retired in 2014 has suffered an apparent breakup, the second time in less than a year that a polar-orbiting weather satellite has generated orbital debris.
“The breakup, if confirmed, would be the second time in less than a year for a satellite in polar orbit. In February, the Defense Meteorological Satellite Program Flight 13 satellite exploded in orbit, creating several dozen pieces of debris.”
The Joint Space Operations Center (JSpOC) announced Nov. 25 that it had identified a possible breakup of the NOAA 16 satellite. The center, which tracks objects in orbit and warns of potential collisions, said it first detected the breakup at 3:41 a.m. Eastern time and was tracking an unspecified number of “associated objects” in the orbit of NOAA 16.
JSpOC said later Nov. 25 that the debris from NOAA 16 posed no current threat to other satellites in orbit. It added that it did not believe the debris resulted from a collision with another object, suggesting that NOAA 16 broke up on its own.
NOAA 16 launched in September 2000 with a planned lifetime of three to five years. The spacecraft continued to operate in a backup role until June 2014, when NOAA retired the spacecraft after an unspecified “critical anomaly.”
“A sudden temperature spike in that spacecraft led spacecraft engineers to conclude a battery in the spacecraft ruptured because of a design flaw. Seven other DMSP spacecraft have a similar design flaw.”
