Question: What spacecraft used the gravitational pull of the planet that the trophy awarded at the annual Montreal fireworks festival, takes its name from?

full_context: Document 1: Boston: There are several major annual events such as First Night, which occurs on New Year's Eve, the Boston Early Music Festival, the annual Boston Arts Festival at Christopher Columbus Waterfront Park, and Italian summer feasts in the North End honoring Catholic saints. The city is the site of several events during the Fourth of July period. They include the week-long Harborfest festivities and a Boston Pops concert accompanied by fireworks on the banks of the Charles River.
Document 2: Jupiter: Since 1973 a number of automated spacecraft have visited Jupiter, most notably the Pioneer 10 space probe, the first spacecraft to get close enough to Jupiter to send back revelations about the properties and phenomena of the Solar System's largest planet. Flights to other planets within the Solar System are accomplished at a cost in energy, which is described by the net change in velocity of the spacecraft, or delta-v. Entering a Hohmann transfer orbit from Earth to Jupiter from low Earth orbit requires a delta-v of 6.3 km/s which is comparable to the 9.7 km/s delta-v needed to reach low Earth orbit. Gravity assists through planetary flybys can be used to reduce the energy required to reach Jupiter, albeit at the cost of a significantly longer flight duration.
Document 3: London: There is a variety of annual events, beginning with the relatively new New Year's Day Parade, fireworks display at the London Eye, the world's second largest street party, the Notting Hill Carnival is held during the late August Bank Holiday each year. Traditional parades include November's Lord Mayor's Show, a centuries-old event celebrating the annual appointment of a new Lord Mayor of the City of London with a procession along the streets of the City, and June's Trooping the Colour, a formal military pageant performed by regiments of the Commonwealth and British armies to celebrate the Queen's Official Birthday.
Document 4: Gravity assist: In orbital mechanics and aerospace engineering, a gravitational slingshot, gravity assist maneuver, or swing - by is the use of the relative movement (e.g. orbit around the Sun) and gravity of a planet or other astronomical object to alter the path and speed of a spacecraft, typically to save propellant and reduce expense. Gravity assistance can be used to accelerate a spacecraft, that is, to increase or decrease its speed or redirect its path. The ``assist ''is provided by the motion of the gravitating body as it pulls on the spacecraft. The gravity assist maneuver was first used in 1959 when the Soviet probe Luna 3 photographed the far side of Earth's Moon and it was used by interplanetary probes from Mariner 10 onwards, including the two Voyager probes' notable flybys of Jupiter and Saturn.
Document 5: Houston: Many annual events celebrate the diverse cultures of Houston. The largest and longest running is the annual Houston Livestock Show and Rodeo, held over 20 days from early to late March, is the largest annual livestock show and rodeo in the world. Another large celebration is the annual night-time Houston Pride Parade, held at the end of June. Other annual events include the Houston Greek Festival, Art Car Parade, the Houston Auto Show, the Houston International Festival, and the Bayou City Art Festival, which is considered to be one of the top five art festivals in the United States.
Document 6: Force: Newton came to realize that the effects of gravity might be observed in different ways at larger distances. In particular, Newton determined that the acceleration of the Moon around the Earth could be ascribed to the same force of gravity if the acceleration due to gravity decreased as an inverse square law. Further, Newton realized that the acceleration due to gravity is proportional to the mass of the attracting body. Combining these ideas gives a formula that relates the mass () and the radius () of the Earth to the gravitational acceleration:
Document 7: 2002 AA29: When 2002 AA29 is approaching the Earth from in front (i.e. it is moving slightly slower, and the Earth is catching it up), the gravitational attraction of the Earth shifts it onto a slightly faster orbit, a little nearer the Sun. It now hurries ahead of the Earth along its new orbit, until after 95 years it has almost lapped the Earth and is coming up from behind. Again it comes under the Earth's gravitational influence; this time it is lifted onto a slower orbit, further from the Sun. On this orbit it can no longer keep pace with the Earth, and it falls behind until in 95 years it is once again approaching the Earth from in front. The Earth and 2002 AA29 chase each other in turn around the Sun, but do not get close enough to break the pattern.
Document 8: Saturn: In November 1980, the Voyager 1 probe visited the Saturn system. It sent back the first high-resolution images of the planet, its rings and satellites. Surface features of various moons were seen for the first time. Voyager 1 performed a close flyby of Titan, increasing knowledge of the atmosphere of the moon. It proved that Titan's atmosphere is impenetrable in visible wavelengths; therefore no surface details were seen. The flyby changed the spacecraft's trajectory out from the plane of the Solar System.Almost a year later, in August 1981, Voyager 2 continued the study of the Saturn system. More close-up images of Saturn's moons were acquired, as well as evidence of changes in the atmosphere and the rings. Unfortunately, during the flyby, the probe's turnable camera platform stuck for a couple of days and some planned imaging was lost. Saturn's gravity was used to direct the spacecraft's trajectory towards Uranus.The probes discovered and confirmed several new satellites orbiting near or within the planet's rings, as well as the small Maxwell Gap (a gap within the C Ring) and Keeler gap (a 42 km wide gap in the A Ring).
Document 9: Space Race: In 1958, Korolev upgraded the R-7 to be able to launch a 400-kilogram (880 lb) payload to the Moon. Three secret 1958 attempts to launch Luna E-1-class impactor probes failed. The fourth attempt, Luna 1, launched successfully on January 2, 1959, but missed the Moon. The fifth attempt on June 18 also failed at launch. The 390-kilogram (860 lb) Luna 2 successfully impacted the Moon on September 14, 1959. The 278.5-kilogram (614 lb) Luna 3 successfully flew by the Moon and sent back pictures of its far side on October 6, 1959.
Document 10: Solar System: Kepler's laws of planetary motion describe the orbits of objects about the Sun. Following Kepler's laws, each object travels along an ellipse with the Sun at one focus. Objects closer to the Sun (with smaller semi-major axes) travel more quickly because they are more affected by the Sun's gravity. On an elliptical orbit, a body's distance from the Sun varies over the course of its year. A body's closest approach to the Sun is called its perihelion, whereas its most distant point from the Sun is called its aphelion. The orbits of the planets are nearly circular, but many comets, asteroids, and Kuiper belt objects follow highly elliptical orbits. The positions of the bodies in the Solar System can be predicted using numerical models.
Document 11: Voyager 1: After completing its primary mission with the flyby of Saturn on November 12, 1980, Voyager 1 became the third of five artificial objects to achieve the escape velocity that will allow them to leave the Solar System. On August 25, 2012, Voyager 1 became the first spacecraft to cross the heliopause and enter the interstellar medium.
Document 12: Montreal International Jazz Festival: The Festival International de Jazz de Montréal (English: Montreal International Jazz Festival) is an annual jazz festival held in Montreal, Quebec, Canada. The Montreal Jazz Fest holds the 2004 Guinness World Record as the world's largest jazz festival. Every year it features roughly 3,000 artists from 30 - odd countries, more than 650 concerts (including 450 free outdoor performances), and welcomes over 2 million visitors (12.5% of whom are tourists) as well as 300 accredited journalists. The festival takes place at 20 different stages, which include free outdoor stages and indoor concert halls.
Document 13: Detroit: Annual summer events include the Electronic Music Festival, International Jazz Festival, the Woodward Dream Cruise, the African World Festival, the country music Hoedown, Noel Night, and Dally in the Alley. Within downtown, Campus Martius Park hosts large events, including the annual Motown Winter Blast. As the world's traditional automotive center, the city hosts the North American International Auto Show. Held since 1924, America's Thanksgiving Parade is one of the nation's largest. River Days, a five-day summer festival on the International Riverfront lead up to the Windsor–Detroit International Freedom Festival fireworks, which draw super sized-crowds ranging from hundreds of thousands to over three million people.
Document 14: Plymouth: Outdoor events and festivals are held including the annual British Firework Championships in August, which attracts tens of thousands of people across the waterfront. In August 2006 the world record for the most amount of simultaneous fireworks was surpassed, by Roy Lowry of the University of Plymouth, over Plymouth Sound. Since 1992 the Music of the Night has been performed in the Royal Citadel by the 29 Commando Regiment and local performers to raise money for local and military charities.
Document 15: Fireworks competitions: Known officially as L'International des Feux Loto - Québec, the Montreal Fireworks Festival is the most prestigious and largest fireworks competition in the world. It is an annual international competition held in Montreal, Quebec, Canada since 1985. The event begins in June and carries on until August. Each summer, several pyrotechnical companies from different countries present a 30 - minute - long pyromusical show. Gold, Silver and Bronze Jupiter trophies are awarded to the winners. The Jupiters have become symbols of prestige within the fireworks industry. See the festival's. The fireworks are synchronized to music which is also broadcast over a local radio station. Over 3 million spectators gather each year to see the fireworks. The main viewing locations are: the Jacques - Cartier Bridge (closed to traffic the evening of each event), La Ronde (amusement park), and on either side of the St. Lawrence River. Approximately 6,000 fireworks are set off during each show.
