Back-Step Time Sphere - Time travel vehicle powered by 100% alien technology featured on the sci-fi series SEVEN DAYS/UPN/1998-2001. Based in the deserts of southern Nevada in an area called Never Never Land, the top-secret Back-Step project credits its existence to alien technology retrieved by the US Government after a crash of a UFO (Unidentified Flying Object) in Roswell, New Mexico in 1954. Using fuel found in the alien spacecraft,  members of the Back-Step project routinely send a large blue geodesic-shaped sphere back in time seven days to change the course of history. The reason for going only 7 days is due to the regeneration of the alien fuel and its critical mass. The first Back-Step mission occurred when an atomic bomb destroyed  Washington DC and the Back-Step team went back in time to prevent the tragedy. Their mission was successful but, changing history can be a tricky and a politically sensitive issue. Who's important enough to save? Is it in the best interests of the government to stop a tragedy, assassination, or natural disaster? However, when the decision is made to launch a Back-Step mission, Project Head Dr. Bradley Talmadge (Alan Scarfe), who reports to the NSA, mobilizes his troops into action. His staff included Lt. Frank Parker (Jonathan La Paglia), the chief Back-Step Chrononaut (time traveler), a former Navy SEAL and CIA black ops operative with a photographic memory and an extreme threshold for pain;  Dr. Olga Vukavitch (Justina Vail), a brilliant, sexy Russian scientist (she defected from a now defunct Russian time travel project after her husband died in a failed experiment); Captain Craig Donavan (Don Franklin), a US Navy Officer, chief military adviser and Chrononaut in training (he served with Parker in the Navy SEALS); Dr. Isaac Mentnor (Norman Lloyd), head of the project and creator of Back-Step; Dr. John Ballard (Sam Whipple), a wheelchair-bound time travel specialist; Andrew "Hooter" Owsley (Kevin Christy),  Ballard's protegê, science specialist and cyber-hacker who replaced Ballard when he left for a leave of absence; and Nate Ramsey (Nick Searcy), the cynical but ultra patriotic project Security Chief. Nate and Frank Parker have what you would call an adversarial relationship. Nate hates Parker's rebellious, independent spirit, thinks Frank is an undisciplined loser and not the right man for the job. Parker, on the other hand, thinks Ramsey is an uptight idiot. But both put their feeling in check for the good of the Back-Step project. Once when Nate accidentally ran over his deaf dog while it slept under his car, Frank warned Nate to check under his car during one of the Back-Step missions (Awww! He saved the widdle doggie). When Frank takes on a mission he wears an orange flight suit and a large bubble-shaped helmet. As he travels back in time, his cockpit shakes violently while images of the past seven days are seen in reverse. When Parker arrives in the past he quickly reports in by using the password code "Conundrum." Parker explained his job as Chrononaut saying "The Chrononauts, fix things, accidents, terrorism. They prevent things from happening. If you know what already happened you get into the big blue sphere and go back and fix it."  When asked about the rigors of time travel, Frank explained traveling through time was like riding inside of a food blender.
