If we send astronauts to Mars, there will be a time delay anytime we send or receive messages to them here on Earth. Given that Mars is an average of 54.6 million km away from Earth, how long is this time delay for a 2-way 'round-trip' communication - sent to Earth, then back to Mars? (this might be important in emergency situations)
answer choices
a)About 4 minutes.
b)About 30 seconds.
c)About 10 seconds.
d)About 6 minutes.
In Table 2, there is a list of 15 planets, some of which are real objects discovered by the Kepler space telescope, and some are hypothetical planets. For each one, you are provided the temperature of the star that each planet orbits in degrees Kelvin (K), the distance that each planet orbits from their star in astronomical units (AUs) and the size or radius of each planet in Earth radii (RE). Since we are concerned with finding Earth-like planets, we will assume that the composition of these planets are similar to Earth's, so we will not directly look at their masses, rather their sizes (radii) along with the other characteristics. Determine which of these 15 planets meets our criteria of a planet that could possibly support Earth-like life. Use the Habitable Planet Classification Flow Chart (below) to complete Table 2. Whenever the individual value you are looking at falls within the range of values specified on the flow chart, mark the cell to the right of the value with a Y for…

- Since 1995, hundreds of extrasolar planets have been discovered. There is the exciting possibility that there is life on one or more of these planets. To support life similar to that on the Earth, the planet must have liquid water. For an Earth-like planet orbiting a star like the Sun, this requirement means that the planet must be within a habitable zone of 0.9 AU to 1.4 AU from the star. The semimajor axis of an extrasolar planet is inferred from its period. What range in periods corresponds to the habitable zone for an Earth-like Planet orbiting a Sun-like star?arrow_forwardMake a short report on vehicles used for space missions recently.arrow_forwardThe Lunatik is a military spacecraft on extended patrol in the vicinity of the planet Eqrgp and its moon, with the mission of repelling Vegan invaders who threaten life on Eqrgp or on its moon. The Vegans' home base is on a planet of the star Vega. As it happens, Vegans are vegans, but still very vicious toward non-Vegan life forms, especially non-vegan ones. The captain of the Lunatik endangers his craft's vital mission by running out of fuel, leaving the Lunatik adrift in space, subject to the gravitational pulls of Eqrgp and its moon. Ignore the gravitational pulls of other bodies. The Lunatik's navigator notices that for a short while the craft does not change its speed or direction. How far from the center of Eqrgp is the Lunatik at that time? The distance between the centers of Eqrgp and its moon is 3.91 x 10 m.
