Lunar Link: Artemis II’s Global Network Keeps Crew Connected

NASA’s Artemis II will carry four astronauts around the Moon with comms routed through the Near Space Network and the Deep Space Network under the SCaN program; the mission will test the Orion Artemis II Optical Communications System (laser links) to move data faster than radio, while a ~41-minute blackout behind the Moon is managed via data compression and rapid reacquisition by DSN; NASA and partners are also pursuing a Lunar Relay and Navigation System to eliminate blackouts for Artemis III and beyond.

Global Volunteers to Track Artemis II Moon Mission

NASA selected 34 global volunteers—ranging from government agencies and academia to commercial partners and amateur-radio groups—to passively track the Orion spacecraft during Artemis II’s roughly 10-day mission around the Moon. Volunteers will submit data to NASA’s SCaN program to help assess tracking capabilities and build a resilient public-private ecosystem for future Moon and Mars exploration; no funds are exchanged. Artemis II will launch the SLS rocket with a four-person crew, continuing NASA’s plan to advance deep-space exploration.

Goldstone's DSN Antenna Offline Through May for Major Upgrades

NASA says the DSS-14 70-meter antenna at Goldstone is offline after last fall’s damage and will not return until May 1, with a long upgrade planned for 2026–2028; in the meantime, DSN relies on DSS-13 and a Green Bank bistatic radar setup. Artemis 2’s upcoming flight will increase DSN demand, driving infrastructure upgrades to improve resilience for future missions and ongoing planetary radar work (e.g., asteroid characterization such as Apophis).

NASA's MAVEN Goes Silent: Is Mars' Orbiter Lost?

NASA's MAVEN orbiter, studying Mars' upper atmosphere, went offline on December 6 and NASA now says recovery is very unlikely as it appears to be rotating unexpectedly; a Martian solar-conjunction window ending around January 16 could offer one last chance to reestablish contact, though the agency notes that other Mars spacecraft can still relay communications to Earth.

NASA’s MAVEN Mars Orbiter Goes Silent, Likely Lost to Contact

NASA’s MAVEN orbiter, which has studied Mars’ upper atmosphere for over a decade, went offline in December. NASA later acknowledged MAVEN was rotating unexpectedly and is very unlikely to be recovered, though Mars’s solar conjunction could offer another contact window. In the meantime, three other spacecraft can relay data to Earth, and NASA continues root-cause analyses while exploring future options such as a revived Mars Telecommunications Orbiter.

NASA's Deep Space Network Antenna Sustains Damage

A key 70-meter antenna (DSS-14) at NASA's Deep Space Network in Goldstone, California, was damaged in September and remains offline, potentially impacting communication with deep space missions. The incident has added to existing concerns about the overstretched network, which is crucial for missions like Artemis, James Webb, and Voyager 2, amid budget constraints and increasing mission demands.

"NASA Resolves Voyager 1 Communication Breakdown"

NASA engineers are making progress in solving the communication breakdown issue with Voyager 1, the first human-made object to leave the solar system. The problem seems to stem from the spacecraft's flight data subsystem (FDS). A recent signal detected by the Voyager mission team contained a readout of the FDS' entire memory, providing valuable information for troubleshooting. Despite the distance of 15 billion miles from Earth, NASA is working to decode this signal and restore communication with the pioneering space mission.

"NASA's Breakthrough Hybrid Antenna Enhances Deep Space Communication"

NASA has upgraded its Deep Space Network with a hybrid antenna capable of receiving both radio frequency and laser signals, marking a significant advancement in deep space communication. The experimental antenna, located at the California facility, successfully tracked and decoded a signal from a gold-capped laser transceiver attached to NASA’s asteroid probe Psyche, demonstrating synchronous radio and optical frequency deep space communications for the first time. This upgrade aims to meet the increasing demand for data transmission from deep space missions, with the hybrid antenna achieving data transfer speeds 40 times faster than traditional radio frequency communications at a distance of 20 million miles. The new technology paves the way for more efficient communication with future space explorations and enables the rapid transfer of high-resolution images and extensive scientific data from distant space missions.

"Revolutionizing Space Exploration with Cutting-Edge Laser Technology"

NASA's Deep Space Network (DSN), the communication infrastructure that connects spacecraft with engineers and scientists on Earth, is struggling to handle the increasing data load from a growing number of missions. Thousands of hours of science observations are being lost, and the network is oversubscribed by up to 40%. To meet the demands of future space exploration, experts suggest turning to laser communications, which can provide higher bandwidth and alleviate the strain on the DSN. NASA is already testing optical communications systems, and while there are challenges to overcome, such as cloud cover and spacecraft tumbling, optical communications could be a game changer for transmitting large quantities of data in the future.

"NASA's Deep Space Network Faces Uncertain Future, Officials Warn"

NASA officials have expressed concerns about the future of the Deep Space Network (DSN), a crucial system used to maintain contact with missions across the Solar System. With around 40 missions currently relying on the DSN, and another 40-plus missions expected to join in the next decade, the network is becoming oversubscribed and stressed. The upcoming Artemis missions, which involve astronauts and require high data transmission rates, will further strain the aging infrastructure of the DSN. NASA officials highlighted the need for upgrades and improvements to ensure the network's continued functionality and support for future space exploration endeavors.

NASA's Deep Space Network Faces Critical Point Amid Growing Demand, Confirms Multi-Year Delay in Next New Frontiers Competition

NASA's Deep Space Network (DSN), a system of antennas used for communications with spacecraft beyond Earth orbit, is facing increasing demand and decreasing budgets, putting its ability to support science missions and Artemis lunar expeditions at risk. The recent Artemis 1 mission highlighted the challenges faced by the DSN, with the spacecraft and cubesats taking up a significant amount of DSN time, causing delays and impacting science missions. The DSN's workload is expected to double with future Artemis missions and other lunar missions, while its budget has decreased. Efforts to enhance the DSN with new antennas are behind schedule and over budget. NASA is implementing upgrades, international partnerships, and new antennas, but the aging infrastructure and constrained budgets pose significant concerns for the network's future capacity and operations.

Webb Scope's Data Download: A 6-Month Scheduling Scramble

NASA has revealed that the process of downloading data from the James Webb Space Telescope (JWST) involves a six-month scramble to secure network resources. The JWST communicates with Earth through the Deep Space Network (DSN), which also handles communications with several other missions. NASA's Mission Operations Center (MOC) works with the Space Telescope Science Institute (STScI) and the Jet Propulsion Laboratory (JPL) to schedule time for the JWST to communicate and download data. The DSN allocates different types of radio waves for communication, with the more powerful Ka-band frequencies used to send scientific data. The team contacts the JWST multiple times per day, maintaining communications for several hours at a time.
