On March 30, 2017, SpaceX did something no space program had done before: They relaunched an orbital class rocket from Earth that had successfully achieved lift-off just a year earlier. It wasn't the first time Elon Musk's company broke new ground: In December 2015, it nailed the landing on a reusable rocket—the first time that had been done—and five months later landed a rocket on a droneship in the middle of the ocean, which was also unprecedented. These feats marked significant moments in the history of space travel, but they were just a few of the steps in the long, messy journey to achieve them. In SpaceX's new blooper reel, spotted by Ars Technica, you can see just some of the many failures the company has had along the way.

The video demonstrates that failure is an important part of the scientific process. Of course when the science you're working in deals with launching and landing rockets, failure can be a lot more dramatic than it is in a lab. SpaceX has filmed their rockets blowing up in the air, disintegrating in the ocean, and smashing against landing pads, often because of something small like a radar glitch or lack of propellant.

While explosions—or "rapid unscheduled disassemblies," as the video calls them—are never ideal, some are preferable to others. The Falcon 9 explosion that shook buildings for miles last year, for instance, ended up destroying the $200 million Facebook satellite onboard. But even costly hiccups such as that one are important to future successes. As Musk once said, "If things are not failing, you are not innovating enough."

Send Your Name to Space on NASA's Latest Mars Lander

Humans may not reach Mars until the 2030s (optimistically), but you can get your name there a whole lot sooner. As Space.com reports, NASA is accepting names from the public to be engraved on a small silicon microchip that's being sent into space with their latest Mars lander, InSight.

All you have to do is submit your name online to NASA, and the space agency will put it on the lander—in super-tiny form, of course—which will set off for Mars in May 2018.

This is the public's second shot at getting their name to Mars: NASA first put out a call for names to go to the Red Planet with InSight in 2015. The planned 2016 launch was delayed over an issue with one of the instruments, and since the naming initiative was so popular—almost 827,000 people submitted their names the first time around—they decided to open the opportunity back up and add a second microchip.

NASA is encouraging people to sign up even if they've sent in their names for other mission microchips. (The space agency also sent 1.38 million names up with Orion's first test flight in 2014.) You can put your name on both of InSight's microchips, in other words, as well as any future missions. The agency's "frequent flyer" program allows you to keep track of every mission to which your name is attached. Interplanetary fame, here you come.

You can submit your name for the InSight mission until November 1 using this form. If you miss the deadline, though, don't worry too much: You'll soon be able to submit your name for Exploration Mission-1's November 2018 launch.

11 Out-of-This-World Facts About Carl Sagan
Original image

Carl Sagan was perhaps America’s most beloved scientific visionary since Albert Einstein. Both a gifted astronomy researcher and an incredible communicator, he brought the wonders of the universe to the masses with his popular TV series Cosmos and books like the Pulitzer Prize–winning Dragons of Eden and Pale Blue Dot. His only novel, Contact, later became a sci-fi movie starring Jodie Foster and Matthew McConaughey. Here are a few things you might not know about the scientist, TV star, and amateur turtleneck model.

1. HARVARD PASSED ON HIRING HIM.

After Sagan served five years at the esteemed university as an assistant professor, Harvard denied him tenure in 1967, in part because one of his mentors at the University of Chicago derided his work as needlessly wordy and useless. He took a job at Cornell instead, where he stayed on as a professor until his death in 1996.

2. HE DICTATED ALL OF HIS WRITING TO AN AUDIO RECORDER.

Sagan was an avid self-editor. A total of 20 drafts of Sagan’s 1994 book Pale Blue Dot exist today in the Library of Congress, each filled with handwritten edits, annotations, and revisions by the author. However, he drafted all of his writing—even grant proposals—by dictating his ideas onto a cassette. The contents were then transcribed for him and returned for editing.

3. HE CONSIDERED WRITING A CHILDREN’S BOOK CALLED HOW DO BIRDS FLY?

In 1993, Sagan brainstormed a long list of possible children’s books for a series structured around the theme of “why?” Other potential ideas included Why Is It Warm In Summer?, Why Are There Lakes?, and What Is Air?

4. HE DIDN’T LIKE THE SPACE SHUTTLE PROGRAM.

Sagan argued against funding NASA’s Space Shuttle program in favor of more robotic exploration of the farther reaches of space. “That’s not space exploration,” he said in an interview about the space shuttle program’s week-long orbits. “Space exploration is going to other worlds.” A space station would only be worth it, he argued, if it was preparing humans for long-term journeys to space, he told Charlie Rose in 1995.

5. HE WAS AN EARLY CRUSADER AGAINST CLIMATE CHANGE.

Sagan’s 1960 Ph.D. thesis concerned the atmosphere of Venus. His theoretical model showed that the planet’s extremely high surface temperatures were due to the greenhouse effect of an atmosphere filled with carbon dioxide and water vapor. In his book Cosmos, he wrote, “The surface environment of Venus is a warning: something disastrous can happen to a planet rather like our own.”

6. HE HAS AN ARCHIVE IN THE LIBRARY OF CONGRESS ENDOWED BY THE CREATOR OF FAMILY GUY.

Family Guy creator Seth McFarlane put up an undisclosed sum to help the Library of Congress buy more than a thousand boxes of material kept by the late scientist and his wife and collaborator, Ann Druyan. The papers in The Seth MacFarlane Collection of Carl Sagan and Ann Druyan Archive, which opened in 2013, include some of Sagan’s earliest notebooks and report cards.

7. HE BECAME FAMOUS FOR A PHRASE HE NEVER SAID.

After Sagan appeared in several successful spots on the Tonight Show Starring Johnny Carson, Carson saw fit to send up the scientist’s signature style (turtleneck included) in a parody sketch.

Carson’s exaggerated use of “billions and billions” would later become associated with the astronomer, though he didn’t use it himself. However, Sagan did talk about large numbers quite a lot, as this supercut shows.

8. HE AND ANN DRUYAN DATED FOR ONE PHONE CALL—AND WERE ENGAGED BEFORE HANGING UP.

Sagan and Druyan, who would create the TV show Cosmos together, fell in love while working on the Voyager message. The courtship was exceedingly brief, as NPR's Radiolab describes:

“After searching endlessly for a piece of Chinese music to put on the record, Druyan had finally found a 2500-year-old song called ‘Flowing Stream.’ In her excitement, she called Sagan and left a message at his hotel. At that point, Druyan and Sagan had been professional acquaintances and friends, but nothing more. But an hour later, when Sagan called back, something happened. By the end of that call, Druyan and Sagan were engaged to be married."

9. HE WANTED TO LEGALIZE POT.

Under the pseudonym “Mr. X,” Sagan wrote a 1969 essay for Time magazine about the personal benefits he’d seen from cannabis use. Then in his mid-30s, he admitted to smoking throughout the prior decade. “I find that today a single joint is enough to get me high,” he wrote, going on to observe that marijuana had enhanced his appreciation for art and music. He concluded that “the illegality of cannabis is outrageous, an impediment to full utilization of a drug which helps produce the serenity and insight, sensitivity and fellowship so desperately needed in this increasingly mad and dangerous world.”

10. HE THOUGHT STAR TREK WAS TOO WHITE.

“In a global terrestrial society centuries in the future, the ship’s officers are embarrassingly Anglo-American. In fact, only two of 12 or 14 interstellar vessels are given non-English names, Kongo and Potemkin,” he wrote in a piece about the impact of science fiction on his life in The New York Times in 1978.

11. HE WANTED US TO LEAVE MARS ALONE.

Despite his passion for exploring space, Sagan argued for the preservation of Mars even if it meant limiting our exploration of the planet. In Cosmos, Sagan declared:

“If there is life on Mars, I believe we should do nothing with Mars. Mars then belongs to the Martians, even if the Martians are only microbes. The existence of an independent biology on a nearby planet is a treasure beyond assessing, and the preservation of that life must, I think, supersede any other possible use of Mars.”
