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]?
Which of these surface features, discovered by the first spacecraft mission (Mariner 4) to Mars, was NOT expected to be seen on Mars?
Answers:
A.
craters
B.
giant volcanoes
C.
expansive canyons
D.
canals
E.
running water
