In 2014, NASA's Deep Space Network (DSN) celebrated its 50 th year of enabling exploration of the Moon, Solar System planets, and beyond. During those 50 years, the DSN has grown along with the associated spacecraft flight systems, providing some 13 orders of magnitude communications systems improvement. It has also contributed to many of the world's most important scientific discoveries and provided substantial technological spinoffs that have become part of everyday life on Earth. Studies of the next 25 years indicate that deep space missions will need an order of magnitude increased communications performance per decade -and this is likely to continue beyond that time. As exhibited by this meeting, another major change happening right now is the emergence of a standardized international community for tracking deep space missions. The future definitely involves increased international cooperation. This paper explains the near term plans already underway for the DSN. We also consider the plans and possibilities for deep space optical communications. Finally, we will discuss opportunities for international participation in the next 50 years of deep space exploration.

“…SNSPDs have also been employed in receivers for space-to-ground classical communications such as the NASA 2014 LADEE Lunar Laser Communications (LLCD) demonstration [179]. SNSPDs are expected to be deployed for the upcoming NASA Deep Space Optical Communications (DSOC) mission [180] and are under consideration for futuristic proposals such as Breakthrough Starshot [181]. Waveguide integrated SNSPDs [153 -155] offer a scalable platform for photonic computing with single photon signals.…”

The ability to detect individual light quanta -single photons -is prized across many fields of physics from astronomy to quantum optics. Superconducting photon detectors offer exceptional performance in terms of sensitivity, spectral range and timing resolution. In this review we introduce the underlying physics of photon absorption in superconducting devices. We then present detailed case studies of contemporary superconducting detector technologies for photon counting at visible and infrared wavelengths. We conclude with a perspective on future developments in this exciting area.

“…For eye-safe reasons, broad atmospheric transmission window, and leverage high-reliability fiber-optic WDM component technology and supplier base, development of wideband, space-qualified, 1.5-µm Er-doped fiber amplifiers is preferred. Such lasers operating with pulse position modulation (PPM) format are planned to be deployed in the near future for NASA's Psyche Mission as part the deep space optical communication (DSOC) technology demonstration 4 . Specifically the mission includes a 4W Downlink transmitter 5 that will be used to extend link demonstrations from 0.1 to farther than 2 AU with data rates up to 250MBit/sec.…”

“…The development of a wideband, high power, gain-flat, space-qualified, WDM 1.5-µm transmitters can support NASA-SCaN roadmap, for high data rates, multiple wavelength channels, optical relay network, crosslink and multi-access configuration. For future DSOC systems higher power transmitter allow for more robust and reliable DSOC communicaiton links including operation under small sun-probe-earth-angle (SPE) 4 . High Power Wavelength Division Multiplexing (WDM) technology enables scaling of data rates >x10.…”

Fibertek is developing a power efficient, space qualifiable Eight WDM Channel PPM Downlink Tx Seed LAser Module (SAM) with TDM based FWM Mitigation Capability. SAM will be compatible with space qualifiable, high TRL, 8 WDM channel, 50W WDM Amplifier prototype that was delivered in early 2021. SAM together with the WDM Amplifier will meet all the requirements of a spaceflight DSOC WDM Transmitter. Fibertek has developed a comprehensive multi gain stage 1.5um WDM fiber amplifier numerical model that accurately quantifies the degradation of WDM PPM signals due to FWM. The physics model is used to quantify FWM-PEV for all 2 and 3 overlapping wavelength configurations of PPM orders 256-16. Results are used as inputs to a PPM statistics model that calculates the PEV statistics for all the PPM orders and WDM channels. The significant Improvements of the PEV statistics with the TDM based FWM mitigation using 2 or 3 wavelength subslots are quantified.
