1. Voyager program consists of 2 interstellar probes, Voyager 1 and Voyager 2 that provided and continue to provide data on solar system and interstellar space. Voyager program is best remembered for providing first man-made interstellar object and it provides valuable scientific data for matter beyond the solar system.
2. Edge of the solar system refers to a region where solar winds generated by the sun just reach and beyond it we will encounter the interstellar medium. It is also known as Heliopause. The actual shape of the heliosphere (region dominated by sun and whose outer boundary is heliopause) is not fixed and is still contentious. In simple terms, edge of solar system refers to the region where sun's effect on an object will cease to exist, while interstellar medium will influence the body.
3. Gravitational slingshot is a maneuver that saves time, propellant and cost, by altering the path and speed of a projectile by use of relative motion and gravity of an astronomical body. The slingshot maneuver can be used to speed up or slow down a projectile.
4. Voyager probes experienced a number of problems in space. An important problem is the loss of power over time which will cause instruments to be powerless. Since 2000, there has not been enough power to run UltraViolet spectrophotometer. Over time the equipment run time will have to be prioritized. In 2010, data was lost for 2 weeks, due to scientific data format issues.
5. Voyager mission was launched to study outer solar system, including planets such as Jupiter, Saturn, Uranus, Neptune and Pluto.
6. The most famous difficulty encountered by Apollo 11 was the manual landing of Lunar Module in a spot which was 4 km away from the originally chosen spot (which turned out to be a boulder field). Another issue was the overloading of landing computer.
7. Viking missions were designed to study Mars and to date remains the most expensive and extensive research programs for study of Mars.
8. After reaching the Mars' orbit, Viking missions divided into orbiter and lander. While the former collected information from orbit, the lander spent time on the surface and collected data. Both the lander and orbiter of viking missions failed over time, but not before providing valuable data.
9. Among a number of other missions, Mars Pathfinder landed on Mars and operated for 84 days. Phoenix is another lander mission to Mars.
10. The distance between Mars and Earth means that about 13 minutes are required to send instructions to a vehicle on Mars. This also means that if anything goes wrong, it will be at least 26 minutes before the mission will receive any instructions from us. This is assuming perfect operating conditions. In case there are storms or any other interference, signals may take longer or be lost.
Hope this helps.
