Why the Curiosity Rover is Forbidden From Collecting Water on Mars

In 2015 NASA announced that they found definitive evidence of liquid water on Mars. But while obtaining a physical sample would revolutionize science, it’s forbidden by international law. 

The Outer Space Treaty of 1967 prevents every nation on Earth from sending a mission, robot or human, close to a water source in the fear of contaminating it with life from Earth [PDF]. In its 140-million-mile journey from Earth to Mars, it’s possible that Curiosity has carried harmful microbes all the way from home. Even though NASA tries its best to sterilize all space-traveling equipment before launch by subjecting it to intense ultraviolet light, it still might harbor microbial hitchhikers.

In theory, NASA could turn up the heat and radiation to a level pretty much guaranteed to destroy any microbial life—but that could also end up wiping out the rover’s internal systems. "In order to be completely sterile, they'd have to use really powerful ionizing radiation or heat, both of which would damage the electronics,” University of New South Wales astrobiologist Malcolm Walter told Fairfax Media. "So they go as far as they dare."

Another issue that would prevent Curiosity from investigating the water source is the terrain itself. The slopes where the streaks formed are steep and therefore difficult to navigate. Future Mars rovers could be designed with this hurdle in mind, and they could also come equipped with DNA sequencers to test for life or 3D-printing capabilities to build smaller bots with little to no chance of being contaminated.

Unfortunately, it’s too late for NASA modify the next generation of Mars rovers, which is set to launch in 2020. The European Space Agency says it plans to send an organic molecule analyzer on its 2018 ExoMars mission, though they still wouldn’t be able to test Martian water unless they could guarantee 100 percent sterilization.

The Internet Archive is Making 62 Obscure, Out-of-Print Books Available Online

Dozens of of obscure, out-of-print books are about to become much more accessible thanks to the Internet Archive, the digital archive of public domain media. But to do it, they’ll have to exploit a loophole in a controversial copyright law, as Ars Technica reports.

The Internet Archive is releasing the Sonny Bono Memorial Collection, a group of books from the 1920s and 1930s that are out of print, but still technically under copyright—meaning they’re extremely difficult to get a hold of.

The Sonny Bono Copyright Term Extension Act was a copyright extension law passed in 1998 to extend copyright protections to works published after 1923 (which would otherwise have already entered the public domain) by 20 years. Unfortunately, while Disney may be happy that Mickey Mouse still falls under copyright protections, that also means that less-famous books that are now out of print can’t be made available to the public. But a provision of the law provides for public access for research, allowing nonprofit libraries to distribute the works if they cannot be found elsewhere for a reasonable price.

The Internet Archive explains:

We believe the works in this collection are eligible for free public access under 17 U.S.C. Section 108(h) which allows for non-profit libraries and archives to reproduce, distribute, display, and publicly perform a work if it meets the criteria of: a published work in the last 20 years of copyright, and after conducting a reasonable investigation, no commercial exploitation or copy at a reasonable price could be found.

Libraries don’t tend to take advantage of the law because it takes considerable resources to track down which works are eligible. However, the Internet Archive collaborated with Elizabeth Townsend Gard, a Tulane copyright expert, and a pair of interns to find books that could be scanned and uploaded online legally. Gard has released guidelines for libraries based on this work to help other archives do the same.

The Internet Archive is starting out with 62 books published between 1923 and 1941 (meaning they’re within 20 years of their copyright expiring) and plan to release up to 10,000 more in the near future to be downloaded and read by online users. And the collection will grow each January as more books enter that 20-year window.

The Time Freddy Krueger Became a Nightmare for Will Smith

Fans of Will Smith’s music career may think they’ve heard every album and seen every music video from the actor’s days as one half of the hip-hop duo DJ Jazzy Jeff & the Fresh Prince. Thanks to one ill-timed and poorly conceived effort, however, there’s one performance that aired only a handful of times before being permanently pulled. It has never resurfaced on compilations, on MTV, or even on YouTube. And the fault lies solely with Freddy Krueger, who used something even more dangerous than his razor-fingered glove: a small army of lawyers.

Back in early 1988, Smith and his musical partner Jazzy Jeff (a.k.a. Jeffrey Allen Townes) released their second album, He’s the DJ, I’m the Rapper. It would eventually go platinum, selling 2.5 million copies through 1989 and spinning off the duo’s most successful single, “Parents Just Don’t Understand.”

In late 1987, Townes composed another single, “Nightmare on My Street,” that played with the premise established by the A Nightmare on Elm Street series. In the song, Smith’s dreams are haunted by a scarred bogeyman named “Fred”; a voice modulator mimics the raspy delivery of actor Robert Englund, who portrayed slasher movie icon Freddy Krueger in the Nightmare on Elm Street films. After his run-in, Smith tries calling Jeff to warn him of the threat but it was too late: The killer has gotten to his partner.

Zomba, the parent company behind the album's label, decided the song might be of interest to New Line Cinema, the studio behind the Nightmare film franchise. With the fourth installment, A Nightmare on Elm Street 4: The Dream Master, due to hit theaters in August 1988, Zomba executive Barry Weiss approached New Line with the possibility of collaborating and forwarded a tape of the song.

Weiss’s timing was spot-on. New Line had recently conducted research that indicated that 40 percent of A Nightmare of Elm Street's audience was black, and they felt that tying Krueger into the burgeoning rap and hip-hop industry would help cement his appeal to the demographic. But New Line and Weiss couldn’t come to a financial agreement. Instead, the studio went with The Fat Boys and granted permission for the song “Are You Ready for Freddy?” The video, complete with an appearance by Englund (in character), was released just a few months prior to A Nightmare on Elm Street 4 to raise awareness of the sequel.

Although New Line found their collaborators, Zomba didn’t appear willing to give up on the idea of a Freddy takeoff. “Nightmare on My Street” remained on the album, and Smith and Townes recorded a video intended for distribution on MTV. In it, Smith is stalked by a Freddy-like character who appears in a trench coat and has a wrinkled face. Smith’s lyrics make overt reference to a Krueger-esque appearance. (Fred is “burnt like a weenie.”) The eerie house Smith calls home even bears a passing resemblance to the house in the original Nightmare film.

If Zomba thought they could declare the song and video a parody and be safe from legal action, they were mistaken. Almost immediately, New Line's legal team sent a stern letter demanding the music label recall all copies of the song. When that didn't happen, the studio next sought a preliminary injunction to prevent “Nightmare on My Street” from being aired on MTV or elsewhere, citing copyright infringement and a concern that the video would detract from their collaboration with The Fat Boys.

"We own both a character, Freddy Krueger, and the theme music from Nightmare on Elm Street, both of which are protected under the copyright laws," Seth Willenson, New Line's senior vice president of telecommunications, told the Los Angeles Times in August 1988. “By using Freddy in the Jazzy Jeff song, they've infringed our copyright. We're protecting our rights the same way that George Lucas does, because as far as we're concerned, Freddy Krueger is the Star Wars of New Line Cinema."

Weeks before the release of the film, a judge in New York’s United States District Court would have to decide whether Zomba was entitled to a fair use exemption over a fictional child murderer.

To Zomba’s dismay, judge Robert Ward didn’t buy their argument that “Nightmare on My Street” was nothing more than a Weird Al-style satire. Screening the entire first installment of the film series and the music video, Ward noted that the latter drew considerable influence in tone, mood, and characteristics from the feature. Fred’s voice was scratchy like Englund’s; his glove, though it featured phonograph needles instead of razors, was obviously meant to invoke Krueger’s weapon of choice. Where Zomba saw parody, Ward saw little more than a derivative work of a copyrighted property.

“It is in this month that many individuals will make their decision whether Nightmare IV is a film that they are interested in viewing,” wrote Ward in his decision. “Thus, the telecast of the lower quality DJ Jazzy Jeff video with the somewhat silly and less frightening Freddy could dissuade an unspecified number of individuals from seeing the film.” The injunction was granted, with a full hearing to be held at a later date.

That didn’t happen—both parties settled out of court. While the song remained on the record, it began to ship with a disclaimer that it wasn’t associated with New Line; the video, which had aired only briefly on MTV, was pulled, and the court ordered that all copies be destroyed. Whether or not that happened is hard to substantiate, but if the video is lurking in storage somewhere, it has never been excavated. “Nightmare on My Street” has never resurfaced.

If Smith and Townes were bothered by the outcome, they didn’t voice it publicly. Smith even dressed up as Krueger in a 1990 episode of his sitcom, The Fresh Prince of Bel-Air. But there is one additional bit of film trivia to come out of the case: In seeking to resolve the issue, New Line offered DJ Jazzy Jeff and the Fresh Prince a two-film option. If they accepted the roles, their salaries would be deducted from the settlement payout. One of those projects was 1990’s House Party, which the two declined. The roles eventually went to Kid ‘n Play.
