Buzz Aldrin Has New Yorkers Buzzing About Mars

NEW YORK — When Buzz Aldrin's new book landed in stores Tuesday (May 7), starstruck fans turned out in droves to see the legendary Apollo 11 astronaut talk about his vision for creating the first permanent human colony on Mars.

At least 300 people packed into the Barnes & Noble bookstore in Union Square, some carrying stacks of Aldrin's  "Mission to Mars: My Vision for Space Exploration" (National Geographic Books) to be signed, while others just tried to catch a glimpse of the second man ever to walk on the moon.

In the audience, one boy with an Apollo pen made rocket ship noises and at least one baby and one teenage girl separately were dressed in mock NASA astronaut flight suits. Nearly everyone rose to their feet to snap pictures when Aldrin made his entrance. [Buzz Aldrin's Visions for Mars Missions & More (Video)]

"I think it's pretty awesome that he's probably one of the only people in the city right now who has been off this planet," said Philip Gazzara, a Queens man who was excited to stumble on the event on his way to Trader Joe's.

Buzz Aldrin became a household name his star power when he set foot on the moon on July 20, 1969, bounding off the lunar module just after his crewmate, the late Neil Armstrong. But today Aldrin is firmly against sending humans back to the place he famously explored, for now at least.

He thinks the U.S. and a group of international partners need to set their sights on Mars, and ultimately he doesn't want to send astronauts there only to bring them back home. Aldrin envisions sending space pilgrims to colonize the forbidding planet, and his book he lays out a plan to get there, which includes an initial expedition to Mars' largest moon Phobos followed by deep-space cruisers that could ferry people from Earth to Mars.

In a Q&A session with co-author, Leonard David, a veteran space journalist and frequent contributor toSPACE.com, Aldrin touched on the historical implications of putting bootprints on the Red Planet.

"History, hundreds and thousands of years in the future, will observe that moment of making that commitment to do that," Aldrin said. Whichever leader decides to do so, Aldrin added, would exceed Alexander the Great, Genghis Kahn and Christopher Columbus in solar system fame.

Aldrin hopes to have an American president commit to continuous manned Mars exploration by 2019, and he is confident that space officials will have no trouble finding willing pioneers. The astronaut pointed to the 78,000 people who have already applied to become Red Planet colonists with the nonprofit organization Mars One.

Not everyone in the audience was as optomistic about Aldrin's vision. Tom Marshall, who came in from New Jersey, had serious doubts about the plan, hinging on U.S. partnership with other countries like China. "If we don't get along down here, we can't make it up there."

Asked why he came out to see Aldrin, Marshall simply said, "He landed on the moon."

That stark fact proves endlessly captivating to Aldrin's fans and the astronaut handles the inevitable flurry of questions about his Apollo 11 lunar landing with wit. One young boy in the audience asked Aldrin what he did during his trip to the moon, to which the astronaut replied, "We waited until it was time to come home." Another kid asked what it first felt like to step on the moon, and Aldrin answered shortly, "It felt good," teasing that "fighter pilots don't have feelings; we have ice water running through our veins."

Easter Science: 6 Facts About Jesus

He may be the most famous man who ever lived, but surprisingly little is known about his life.

This Sunday (March 31), more than 2 billion Christians will celebrate Jesus Christ's resurrection from the dead. While there is no scientific way to know whether that supernatural event at the heart of Christianity actually happened, historians have established some facts about his life.

From his birth to his execution by the Romans, here are six facts about the historical Jesus.

1. His birth … in a manger?

Most historians believe Jesus was a real man. To test the veracity of biblical claims, historians typically compare Christian accounts of Jesus' life with historical ones recorded by Romans and Jews, most notably the historians Flavius Josephus and Cornelius Tacitus.

And though a manger may or may not have figured prominently in the birth, scholars do agree that Jesus was born between 2 B.C. and 7 B.C. as part of the peasant class in a small village called Nazareth in Galilee. Historians also back the claim that Joseph, Jesus' father, was a carpenter, meaning Jesus would have gone into the family profession as well.

2. A mystical baptism

One of the pivotal moments in the New Testament is Jesus' baptism in the wilderness by a radical mystic named John the Baptist. Most historians believe this event actually occurred, and that Jesus experienced some sort of vision that led him to begin preaching. In the New Testament, Mark 1:10 (The New American Bible, Revised Edition) describes Jesus seeing "the heavens being torn open and the Spirit, like a dove, descending upon him." Jesus is then tempted by Satan in the wilderness for 40 days, the passage continues.

The Jewish historian Josephus mentions the mystical activities of John the Baptist, as well as his execution by King Herod. [History's 10 Most Overlooked Mysteries]

3. Reformer

After his vision, Jesus began to preach that the Earth could be changed into a "Kingdom of God." Jesus' message of reform was deeply rooted in the Jewish tradition, and he likely never viewed himself as creating a new religion per se — just reforming the one he was born into, scholars say.

4. A wise teacher

Josephus not only mentions Jesus, in one passage he also describes him as a wise man and a teacher. (The passage is controversial because many historians believe a Christian author later added in phrases such as "He was the messiah" to the text, leading a few scholars to doubt the authenticity of the passage as a whole). Most historians agree, however, that Jesus was viewed as a teacher and healer in Galilee and Judea.

5. Timing of Jesus' crucifixion

Several sources mention Jesus' crucifixion at the hands of Pontius Pilate, the Roman prefect. Christian Gospels say the skies darkened for hours after the crucifixion, which historians viewed either as a miracle or a portent of dark times to come. Using astronomy, later historians have used this mention to pinpoint the death of Christ. Some tie the crucifixion to a one-minute 59-second total solar eclipse that occurred in 29 C.E., whereas others say a second total eclipse, blocking the sun for four minutes and six seconds, in 33 C.E. marked Jesus' death. (C.E. stands for Common Era or Christian Era, and is an alternative name for anno Domini, or A.D.)

Death by crucifixion was one of the goriest ends the Romans meted out, and it was typically reserved for slaves and those seen to be challenging Roman authority.

6. Historical relics

The historical veracity of various physical relics, such as the crucifixion nails and crown of thorns Jesus wore on the cross, have decidedly less historical or scientific backing. Most scientific studies suggest that these relics originated long after Jesus died. But the most famous relic of Jesus, the shroud of Turin, may be on more solid footing: Whereas some parts of the shroud date to A.D. 1260, other analyses have suggested that the shroud is about as old as Jesus.

Another more recent finding, a scrap of papyrus from the early Christian era referring to Jesus' wife was unveiled last year, to much skepticism. Since then, evidence has come out to suggest the so-called Gospel of Jesus' Wife is a forgery, though the jury may still be out on that relic.

Pagan Roots? 5 Surprising Facts About Christmas

When you gather around the Christmas tree or stuff goodies into a stocking, you're taking part in traditions that stretch back thousands of years — long before Christianity entered the mix.

Pagan, or non-Christian, traditions show up in this beloved winter holiday, a consequence of early church leaders melding Jesus' nativity celebration with pre-existing midwinter festivals. Since then, Christmas traditions have warped over time, arriving at their current state a little more than a century ago.

Read on for some of the surprising origins of Christmas cheer, and find out why Christmas was once banned in New England.

1. Early Christians had a soft spot for pagans

It's a mistake to say that our modern Christmas traditions come directly from pre-Christian paganism, said Ronald Hutton, a historian at Bristol University in the United Kingdom. However, he said, you'd be equally wrong to believe that Christmas is a modern phenomenon. As Christians spread their religion into Europe in the first centuries A.D., they ran into people living by a variety of local and regional religious creeds.

Christian missionaries lumped all of these people together under the umbrella term "pagan," said Philip Shaw, who researches early Germanic languages and Old English at Leicester University in the U.K. The term is related to the Latin word meaning "field," Shaw told LiveScience. The lingual link makes sense, he said, because early European Christianity was an urban phenomenon, while paganism persisted longer in rustic areas.

Early Christians wanted to convert pagans, Shaw said, but they were also fascinated by their traditions.

"Christians of that period are quite interested in paganism," he said. "It's obviously something they think is a bad thing, but it's also something they think is worth remembering. It's what their ancestors did." [In Photos: Early Christian Rome]

Perhaps that's why pagan traditions remained even as Christianity took hold. The Christmas tree is a 17th-century German invention, University of Bristol's Hutton told LiveScience, but it clearly derives from the pagan practice of bringing greenery indoors to decorate in midwinter. The modern Santa Claus is a direct descendent of England's Father Christmas, who was not originally a gift-giver. However, Father Christmas and his other European variations are modern incarnations of old pagan ideas about spirits who traveled the sky in midwinter, Hutton said.

2. We all want that warm Christmas glow

But why this fixation on partying in midwinter, anyway? According to historians, it's a natural time for a feast. In an agricultural society, the harvest work is done for the year, and there's nothing left to be done in the fields.

"It's a time when you have some time to devote to your religious life," said Shaw. "But also it's a period when, frankly, everyone needs cheering up."

The dark days that culminate with the shortest day of the year ­— the winter solstice — could be lightened with feasts and decorations, Hutton said.

"If you happen to live in a region in which midwinter brings striking darkness and cold and hunger, then the urge to have a celebration at the very heart of it to avoid going mad or falling into deep depression is very, very strong," he said.

Stephen Nissenbaum, author of the Pulitzer Prize finalist "The Battle for Christmas" (Vintage, 1997), agreed.

"Even now when solstice means not all that much because you can get rid of the darkness with the flick of an electric light switch, even now, it's a very powerful season," he told LIveScience.

3. The Church was slow to embrace Christmas

Despite the spread of Christianity, midwinter festivals did not become Christmas for hundreds of years. The Bible gives no reference to when Jesus was born, which wasn't a problem for early Christians, Nissenbaum said.

"It never occurred to them that they needed to celebrate his birthday," he said.

With no Biblical directive to do so and no mention in the Gospels of the correct date, it wasn't until the fourth century that church leaders in Rome embraced the holiday. At this time, Nissenbaum said, many people had turned to a belief the Church found heretical: That Jesus had never existed as a man, but as a sort of spiritual entity.

"If you want to show that Jesus was a real human being just like every other human being, not just somebody who appeared like a hologram, then what better way to think of him being born in a normal, humble human way than to celebrate his birth?" Nissenbaum said. [Religious Mysteries: 8 Alleged Relics of Jesus]

Midwinter festivals, with their pagan roots, were already widely celebrated, Nissenbaum said. And the date had a pleasing philosophical fit with festivals celebrating the lengthening days after the winter solstice (which fell on Dec. 21 this year). "O, how wonderfully acted Providence that on that day on which that Sun was born … Christ should be born," one Cyprian text read.

4. The Puritans hated the holiday

But if the Catholic Church gradually came to embrace Christmas, the Protestant Reformation gave the holiday a good knock on the chin. In the 16th century, Christmas became a casualty of this church schism, with reformist-minded Protestants considering it little better than paganism, Nissenbaum said. This likely had something to do with the "raucous, rowdy and sometimes bawdy fashion" in which Christmas was celebrated, he added.

In England under Oliver Cromwell, Christmas and other saints' days were banned, and in New England it was illegal to celebrate Christmas for about 25 years in the 1600s, Nissenbaum said. Forget people saying, "Happy holidays" instead of "Merry Christmas," he said.

"If you want to look at a real 'War on Christmas,' you've got to look at the Puritans," he said. "They banned it!"

5. Gifts are a new (and surprisingly controversial) tradition

While gift-giving may seem inextricably tied to Christmas, it used to be that people looked forward to opening presents on New Year's Day.

"They were a blessing for people to make them feel good as the year ends," Hutton said. It wasn't until the Victorian era of the 1800s that gift-giving shifted to Christmas. According to the Royal Collection, Queen Victoria's children got Christmas Eve gifts in 1850, including a sword and armor. In 1841, Victoria gave her husband, Prince Albert, a miniature portrait of her as a 7-year-old; in 1859, she gave him a book of poetry by Alfred, Lord Tennyson.

All of this gift-giving, along with the secular embrace of Christmas, now has some religious groups steamed, Nissenbaum said. The consumerism of Christmas shopping seems, to some, to contradict the religious goal of celebrating Jesus Christ's birth. In some ways, Nissenbaum said, excessive spending is the modern equivalent of the revelry and drunkenness that made the Puritans frown.

"There's always been a push and pull, and it's taken different forms," he said. "It might have been alcohol then, and now it's these glittering toys."

Is Obama's Commercial Space Plan for NASA About to Take a Wrong Turn? (ContributorNetwork)

One of the warmest supporters of the Obama commercial crew program has sounded the alarm that it may be about to go off the rails. Clark Lindsey, a blogger who champions commercial space, had this to say:

"Unfortunately, there are signs that NASA management may find its own way to undermine the commercial crew program. The statement from the Commercial Spaceflight Federation this week hints that there are moves within NASA to run CCDev not in the commercial services approach taken with COTS, and to a great extent by the USAF with the EELV program, but in the standard NASA top-down, sub-contractor procurement mode. This will bring in a huge array of rules and procedures that will drive costs up and up."

Lindsey goes on to speculate in the comments section of his post that entrepreneurial companies such as SpaceX may want to pull out of the commercial crew plan altogether rather than have to operate under NASA rules.

The statement that Lindsey quotes, which urges a more commercial approach to acquiring space launch services, does seem to hint that NASA may be considering a more traditional NASA/contractor regime to manage the commercial crew program. This would defeat the purpose of doing a commercial space effort, turning SpaceX and other entrepreneurial space companies into another Boeing or Lockheed Martin.

Lindsey's warning is just the latest wrinkle in the debate over the Obama approach to commercial space, which expanded the Commercial Orbital Transportation Systems program, by offering massive subsidies, starting at almost six billion dollars, but perhaps more if necessary. However, if Lindsey's scenario pans out, the old adage that those who accept government money, also has to accept government rules will once again be proven.

One of the reasons for this seems to stem from who in the Obama administration are making the decisions. In contrast to the previous Bush administration, the current regime has a conspicuous lack of people with actual business experience. President Bush, Vice President Cheney, and even NASA Administrator Mike Griffin all had run businesses and met payrolls. They knew how businesses work and how the government could either help or stifle them. Neither President Obama, Science Czar John Holdren, NASA Administrator Charles Bolden, nor NASA Deputy Administrator Lori Garver has any experience running a private company.

Inevitable the Obama people have reverted to the mind-set that government knows best and that it can direct business rather than taking a hands-off approach and allow the commercial sector to do what it does best, provide goods and services at a good price.

One of the other problems with the Obama approach is that there seems to be a lack of encouragement to the commercial space sector to nurture private markets for human space launch services. I, in contrast to the approach taken to build the EELV family of rockets, this is by deliberate design. Obama's people fear that just as a lot of private markets did not materialize for the EELV, private markets for commercial crew, such as space tourism or servicing private space stations like the one planned by Bigelow Aerospace, will not come to fruition. Thus the government is the primary investor and the sole customer for commercial space under the Obama plan.

One possible way out of this is to pass an idea called "Zero Taxes, Zero Gravity" that creates an enterprise zone in space in which goods and services created there would not be taxed. Thus would private markets be created and the commercial space sector would not be so dependent on the government for income.
