The most costly type of interplanetary mission is
an intentional crash-landing on the planet
a hyperbolic flyby of the planet
an orbital mission (getting into an elliptical orbit around the target planet)
a soft landing on the planet
A stated goal of NASA's Space Launch System (SLS) is to
establish a science lab in orbit around the Moon
fly astronauts to the International Space Station
assist in the construction of a large space colony
launch satellites from Earth using a mass driver
The purpose of NASA's Project Constellation, proposed in 2006 and cancelled in 2010, was
to carry astronauts to the International Space Station and eventually the Moon
to send a robotic spacecraft to the Alpha Centauri system
to explore the icy moons of Jupiter
to attempt to alter the trajectory of an asteroid
A lot of asteroid and comet dust collides with Earth's atmosphere everyday. Assume that 500 tons of mass is added to Earth daily from the millions of meteors that enter our atmosphere. Estimate the time it would take for the Earth's mass to increase 0.2% with this impact rate. Is this mass accumulation significant to Earth as a planet.

- The European Space Agency launched a probe called Rosetta in March 2004. In August 2014, Rosetta reached its destination: a comet called 67P/Churyumov-Gerasimenko. Rosetta is the first spacecraft to rendezvous with a comet, and plans to orbit the comet. It contained a lander craft, called Philae. The Philae lander has several scientific instruments onboard, used to study the comet. ALICE is an ultraviolet imaging spectrograph, used to search for noble gases in the comet core. The ALICE instrument uses potassium bromide as one of the compounds in the analysis of noble gases. Potassium bromide has a specific gravity of 2.74. Assume the lander has a liquid sample of potassium bromide onboard that fills a 1.49-gallon [gal] container. What is the mass of the potassium bromide sample in the container, in units of kilograms [kg]?arrow_forwardCalculate how long radio communications from the spacecraft will take when it encounters Mars. The furthest distance from Earth to Mars is 2.66 AU. Remember that 1 AU = 1.5 x 1011 m and that light travels at 3 x 108 m/s. So how long will the radio messages take to travel this greatest distance of 2.66 AU?

- On February 7, 1999, NASA launched a spacecraft with the ambitious mission of making a close encounter with a comet, collecting samples from its tail, and returning the samples to Earth for analysis. This spacecraft, appropriately named Stardust, took almost five years to rendezvous with its objective-comet Wild 2 (pronounced "Vilt 2")-and another two years to return its samples. The reason for the long round trip is that the spacecraft had to make three orbits around the Sun, and also an Earth Gravity Assist (EGA) flyby, to increase its speed enough to put it in an orbit appropriate for the encounter.When Stardust finally reached comet Wild 2 on January 2, 2004, it flew within 147 miles of the comet's nucleus, snapping pictures and collecting tiny specks of dust in the glistening coma. The approach speed between the spacecraft and the comet at the encounter was a relatively "slow" 6200 m/s, so that dust particles could be collected safely without destroying the vehicle.

- You decide to go on an interstellar mission to explore some of the newly discovered extrasolar planets orbiting the star ROTOR. Your spacecraft arrives in the new system, in which there are five planets. ROTOR is identical to the Sun (in terms of its size, mass, age and composition). From your observations of these planets, you collect the following data: Density Average Distance from star (AU] Planet Mass Radius Albedo Temp. [C] Surf. Press.
