Deep Space Network

Messages from Juno and other spacecraft in the far reaches of the solar system are relayed to scientists via NASA’s Deep Space Network (DSN), which was created in 1958. DSN consists of three sets of powerful radio antennae spaced about 120 degrees longitude apart around the world near Barstow, Calif., Canberra, Australia, and Madrid, Spain. The complexes are all situated in bowl-shaped terrain in semi-mountainous rural areas to minimize interference from external radio waves. As Earth rotates, at least one of the DSN antennae is pointed toward the spacecraft at all times. Communications via DSN begin and end at NASA’s Jet Propulsion Laboratory, which manages the system.

Juno unveils Jupiter's secrets

NASA’s Juno mission launched from Cape Canaveral, Fla., on Aug. 5, 2011, and arrived at Jupiter nearly five years later, having traveled 2.8 billion kilometers. Since then, Juno has made a plethora of new discoveries, upturning much of what we thought we knew about the gas giant. What else could it reveal?

Wrangling the data to choose Mars landing sites

NASA has sent four rovers to Mars, and the fifth — the Mars 2020 Rover — is slated to launch in summer 2020 for an early 2021 arrival. Selecting suitable landing sites is a critical and painstaking pre-launch step in ensuring both the technical and scientific success of these missions.

Benchmarks: July 29, 1958: The Birth of NASA

Growing up in the suburbs of Washington, D.C., meant that my house was often frequented by guests who wanted to visit our nation’s capital. Without fail, this meant my family and I would be taking a trip to one of the Smithsonian’s most popular attractions, the National Air and Space Museum. I can’t count the number of times I visited the museum before I left for college, but it was a lot. Although glimpsing the museum’s collection of aircraft and spacecraft was cool at first, I would much rather have spent those afternoons wandering the halls of the National Museum of Natural History.

From space to village: NASA's SERVIR program brings a big picture to local communities

Established in 2005, the joint NASA and U.S. Agency for International Development program SERVIR (named for the Spanish verb “to serve”) puts geospatial satellite images and analysis tools into the hands of local decision-makers around the world to help them deal with natural disasters and plan for changing climates.

Benchmarks: July 15-24, 1975: Apollo-Soyuz mission launches space collaboration

The space race between the United States and the Soviet Union spurred innovations and historic firsts for humankind from Sputnik to the moon landing. However, much of the drive to break through those technological barriers and explore the vast, starry landscape of space was rooted in a desire to display military dominance in space amid the competition and animosity of the Cold War.

Philae: Achievement and disappointment

Rosetta’s Philae lander made the first landing on the surface of a comet when it touched down on Nov. 12, 2014, three months after Rosetta began orbiting 67P. The landing, though historic, did not go as planned, and Philae was unable to accomplish much of the scientific program that had been scheduled for its 10 instruments.
