The Deep Space Network, NASA’s international collection of giant radio antennas used to communicate with spacecraft at the Moon and beyond, helps scientists and engineers use gravity and radio science experiments to learn more about our planetary neighborhood. After reaching a spacecraft reaches its destination, it uses radio antennas to communicate with the Deep Space Network, which in turn transmits radio signals back to the spacecraft. Every spacecraft travels in a predetermined path emitting radio signals as it orbits around its target. Scientists and engineers can infer the spacecraft's location and how fast it's going by measuring changes in the spacecraft's radio signal frequency. This is made possible by the Doppler effect, the same phenomenon that causes a siren to sound different as it travels towards and away from you. The Doppler phenomenon is observed here when the spacecraft and the Deep Space Network antenna move in relation to each other. Differences between the frequency of radio signals sent by the spacecraft as it orbits and signals received on Earth give us details about the gravitational field of a planetary body. For example, if the gravity is slightly stronger, the spacecraft will accelerate slightly more. If gravity is slightly weaker, the spacecraft will accelerate slightly less. By developing a model of the planetary body's gravitational field, which can be mapped as a gravitational shape, scientists and researchers can deduce information about its internal structure. The Deep Space Network was developed by and is managed by NASA’s Jet Propulsion Laboratory (JPL) in Southern California. The antennas of the Deep Space Network are the indispensable link to robotic explorers venturing beyond Earth. They provide the crucial connection for commanding our spacecraft and receiving never-before-seen images and scientific information on Earth, propelling our understanding of the universe, our solar system and ultimately, our place within it. JPL manages the Deep Space Network for the Space Communications and Navigation (SCaN) Program, based at NASA Headquarters within the Space Operations Mission Directorate.

S Somnath, head of the Indian Space Research Organisation Friday said that Chandrayaan-3 will be sent to the Moon in July as the launch window opens on June 12. Isro chief S Somnath was at the India Today Conclave South 2023 to discuss the space quest. "Essentially Chandrayaan-3 is similar to Chandrayaan-2, with the same scientific architecture and mission objective," Somnath said, adding that the launch date will be announced soo

The Suborbital Imaging Spectrograph for Transition region Irradiance from Nearby Exoplanet host stars, or SISTINE, mission launched aboard a NASA sounding rocket from the Arnhem Space Center in Northern Australia on July 6, 2022, at 9:47 a.m. EDT (11:17 p.m. ACST). The mission helped astronomers understand how starlight influences a planet’s atmosphere, possibly making or breaking its ability to support life as we know it.

Aboard the International Space Station, Expedition 69 Flight Engineers Frank Rubio and Steve Bowen of NASA answered questions about life and work on the orbiting laboratory during an in-flight event Aug. 14 with students at the Odyssey Academy in Galveston Texas. Rubio and Bowen are in the midst of a science mission living and working aboard the microgravity laboratory to advance scientific knowledge and demonstrate new technologies. Such research benefits people on Earth and lays the groundwork for future human exploration through the agency’s Artemis missions, which will send astronauts to the Moon to prepare for future expeditions to Mars.

When it comes to space, humans and robots go way back. We rely heavily on our mechanical friends to perform tasks that are too dangerous, difficult, or out of reach for us humans. We’re even working on a new generation of robots that will help us explore in advanced and novel ways. Learn more about the CADRE—Cooperative Autonomous Distributed Robotic Exploration—project and how this new network of mini rovers could enable future self-guided robotic exploration of the Moon, Mars, and beyond

NASA’s Perseverance Mars rover is filling sample tubes with rocky material on the Red Planet as the agency works on the next steps to get them safely back to Earth. The Mars Sample Return campaign would bring samples collected by the Perseverance rover to Earth for detailed study. The campaign involves an international interplanetary relay team, including the European Space Agency (ESA). These samples could answer a key question: did life ever exist on Mars? Aaron Yazzie, who works on the Mars Sample Return campaign, explains the work being done at NASA’s Jet Propulsion Laboratory to ensure the safe return of the sample tubes.

Paul Smith is a night-sky fanatic and photographer. His obsession is sprites: immense jolts of light that flicker high above thunderstorms. Last October, he guided NASA scientist Dr. Burcu Kosar through the backroads of Oklahoma to catch one herself. Although she’d studied sprites for more than 15 years, she hadn’t yet chased one.
