In the continuous quest to find cost-effective ways to explore the planets, NASA engineers have risen to the occasion by developing a variety of new methods inspired by centuries-old, solar-heated hot-air ballo
or anything in between. They orbit at a low altitude(高度) of just a few hundred miles above the Earth's surface or thousands of miles out in space.When it comes to satellites, space engineers have different types of orbits to choose from. The choice of orbit all depends on the ...
In recent years, LASP has led the development ofmultiple CubeSat missionsto explore everything from the sun’s activity tosupernovae in distant galaxies. Unlike larger space missions, which often net a price tag in the hundreds of millions of dollars, engineers can produce CubeSats on the cheap...

in its orbit to observe enough crossing – transits – of the planets in front of the host star to reveal the complex architecture of the system. Engineers optimized Spitzer’s ability to observe transiting planets during Spitzer’s “warm mission,” which began after the spacecraft’s coolant...
Northrop Grumman Space Technology is investing in what it says is a cheaper way to image Earth-size planets orbiting neighboring stars.

I want us, in the next decade, to build a space telescope that'll be able to image an Earth about another star and figure out whether it can harbor life. My colleagues at the NASA Jet Propulsion Laboratory at Princeton and I are working on technology ...
