With each of its 10,000 pulses per second, the laser instrument aboard NASA's ICESat-2 is sending 300 trillion green photons of light to the ground and detecting the few that return: the method it uses to measure Earth’s changing ice. By the morning of Oct. 3, ICESat-2 returned its first height measurements across the Antarctic ice sheet.
NASA has awarded a contract to the California Institute of Technology (Caltech) in Pasadena, California, to continue operations of the agency\'s Jet Propulsion Laboratory (JPL), also in Pasadena.

Solar System: Things to Know This Week
Our solar system is huge, so let us break it down for you. Here are a few things you should know this week:
1. Science at the Edge
As the New Horizons spacecraft speeds away at more than 31,000 miles per hour (14 km/s) it continues to explore the Kuiper Belt, the region of icy bodies beyond Neptune. New Horizons has now twice observed 1994 JR1, a 90-mile-wide object orbiting more than 3 billion miles from the sun.
2. A Spaceship, Refined
This artist’s rendering shows our Europa mission spacecraft, which is being developed for a launch sometime in the 2020s. The mission will place a spacecraft in orbit around Jupiter to explore the giant planet’s moon Europa. This updated concept image shows tow large solar arrays extending from the sides of the spacecraft, to which the mission’s ice-penetrating radar antennas are attached. A saucer-shaped high-gain antenna is also side mounted with a magnetometer boom placed next to it. Find out more about the spacecraft HERE.
3. Sojourn at Saturn
The Cassini spacecraft is hard at work this week, orbiting Saturn to study the planet and its rings. The recent pictures are spectacular, take a look at them HERE.
4. Talking Juno
Our Juno mission arrives at Jupiter on July 4, and that presents a unique opportunity for educators, science communicators and anyone interested in space exploration. We are providing a growing set of Juno-related information resources. Take a look at them HERE.
5. Now THAT’S a Long Distance Call
How do explorers on Earth talk to astronauts and robotic spacecraft flung across the far reaches of space? They use the remarkable technology deployed by our Space Communications and Navigation (SCaN) Program Office. This month, SCaN is celebrating its 10th anniversary of managing the ultimate network. Find out how it works HERE.
