Downlink special issues notice

Hello! This is an announcement that The Downlink has been revived. Rather than simply start again, I have chosen to create two special issues recapping the past three years. The first special issue spans November 2021 to December 2023, while the second special issue spans January 2024 to December 2024.

Due to the size of these pages, as well as the fact that they are non-standard issues, I have instead had this notice sent out. The following issues of volume 3 (Jan - Dec 2025) should be significantly smaller.

Please be aware that, for a variety of reasons, the issues that I create may be published late.

Here are the issues:

• First special issue

• Second special issue

Introduction to Volume 3 Initially launched in late 2010/early 2011 for a run of four months, The Downlink was unpublished for more than nine years, after which a second volume was published from October 2020 to October 2021. This second volume was very different from the first volume, both in style and structure. A December issue was planned (for some reason, the second volume became volume 1 in April 2021), but was never finished. Like with volume 2, this volume 3 was intended to come with changes, though primarily to style. Volume 3 will not feature any significant changes to style or structure. This both provides continuity with the previous volume and allows the contributors to construct each issue relatively easily. However, following volumes may see changes to style, format, and upload schedule. As it is still very early in the year, a discussion on this is not yet necessary, but suggestions of all kinds are always welcome at the talk page.
In the News Blue Ghost Mission 1 and Hakuto-R Mission 2 were launched from Kennedy Space Center on 15 January. They are planned to land in March and April, respectively. On 30 January, Sunita Williams broke Peggy Whitson's record for most time spent on spacewalks by a woman, at 62 hours and 6 minutes total. ISRO successfully docked two SpaDeX satellites on 16 January, making India the fourth country (including the EU) to dock two vehicles in space. Blue Origin's New Glenn launch vehicle completed its maiden flight on 16 January. The payload was successfully placed in orbit, while the first staged failed to land on the recovery ship.
Featured Content The image Jupiter clouds was promoted to Featured Media status on 4 January. It was nominated by MER-C.
Article of the Month Soyuz programme Artist's impression of the Soyuz 19 spacecraft from the Apollo–Soyuz mission The Soyuz programme (/ˈsɔɪjuːz/ SOY-yooz, /ˈsɔː-/ SAW-; Russian: Союз [sɐˈjus], meaning "Union") is a human spaceflight programme initiated by the Soviet Union in the early 1960s. The Soyuz spacecraft was originally part of a Moon landing project intended to put a Soviet cosmonaut on the Moon. It was the third Soviet human spaceflight programme after the Vostok (1961–1963) and Voskhod (1964–1965) programmes. The programme consists of the Soyuz capsule and the Soyuz rocket and is now the responsibility of Roscosmos. After the retirement of the Space Shuttle in 2011, the Soyuz was the only way for humans to get to the International Space Station (ISS) until 30 May 2020 when Crew Dragon flew to the ISS for the first time with astronauts.	Image of the Month Gene Cernan on the Moon Gene Cernan was the eleventh and (as of 2025) last person to ever step foot on the moon. In addition to being an astronaut, he was an aviator in the US Navy and engineer. Apollo 17 was his second Apollo mission, as he served as Apollo 10's lunar module pilot. He died in Houston on 16 January, 2017. He was the first astronaut to be buried at Texas State Cemetery.

In the News On 17 February, as part of a Commercial Lunar Payload Services mission, Intuitive Machines' lunar lander IM-2 was launched on board a Falcon 9. It was also launched with Lunar Trailblazer and Brokkr-2. The European Space Agency's space telescope INTEGRAL was retired on 28 February after 22 years, five months, and one day. It is expected to re-enter Earth's atmosphere in 2029.
Article of the month Family Portrait (Voyager) The Family Portrait of the Solar System taken by Voyager 1 The Family Portrait, or sometimes Portrait of the Planets, is an image of the Solar System acquired by Voyager 1 on February 14, 1990, from a distance of approximately 6 billion km (40 AU; 3.7 billion mi) from Earth. It features individual frames of six planets and a partial background indicating their relative positions. The picture is a mosaic of 60 frames. The frames used to compose the image were the last photographs taken by either Voyager spacecraft (which continued to relay other telemetry afterward). The frames were also the source of the famous Pale Blue Dot image of the Earth. Astronomer Carl Sagan, who was part of the Voyager imaging team, campaigned for many years to have the pictures taken.	Image of the month STS-98 following liftoff Launched on 7 February 2001, STS-98 delivered to the Destiny laboratory module of the International Space Station. Flown by Atlantis, it was the first human spaceflight mission of the 21st century. The shuttle landed at Edwards Air Force Base on 20 February after being docked with the ISS for almost seven days. The crew consisted of Kenneth Cockrell, commander, Mark L. Polansky, pilot, Robert Curbeam, mission specialist 1, Marsha Ivins, mission specialist 2 and flight engineer, and Thomas David Jones, mission specialist 3.

In the News Firefly Aerospace became the first commercial company to successfully achieve a soft landing on the moon on 2 March with the landing of Blue Ghost Mission 1 near Mons Latreille. It lasted the intended length of one lunar day before losing power on 16 March. It was launched with the Hakuto-R Mission 2 lander Resilience and rover Tenacious, which are planned to land in the Mare Frigoris. On 6 March, the IM-2 mission's lunar lander Athena landed on Mons Mouton. Although intact, it landed sideways, preventing it from generating enough power to operate as designed. The mission was declared over the following day. SpaceX Crew-9 splashed down near Tallahassee, Florida on 18 March. Initially planned to launch with a full complement, the extension of Barry Wilmore and Sunita Williams' stay on the ISS resulted in it being launched with only two crew members.
Article of the month Phootprint The Phootprint mission is a candidate for the Mars Robotic Exploration Preparation Programme 2 (MREP-2) at ESA. During 2014, ESA funded a pre-phase A feasibility study and industrial system studies of 8-month duration. Currently, it is in phase A, meaning 'mission definition study.' The mission would last about 3.5 years, including cruise, mapping orbit, 7 days on the surface, and sample return cruise time. The spacecraft would be powered by solar arrays. In August 2015, the ESA-Roscosmos working group on post-ExoMars cooperation, completed a joint study for a possible future Phobos Sample Return mission, and preliminary discussions were held.	Image of the month InSight lander testing The InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) lander was selected from among three options in August 2012. Initially planned to launch in March 2016, an instrument issue delayed the launch to May 2018, the next Earth-Mars launch window. It was successfully launched on 5 May, and landed on Elysium Planitia on 26 November 2018. Taking seismographic and thermographic readings, InSight operated for a total of 4 years and 19 days instead of its planned 2 year mission. The mission was declared over on 21 December, 2022 after contact was lost on 15 December. A re-analysis of some of its data indicates that there may be significant amounts of groundwater in Mars' crust.

In the News On 1 April, Fram2 became the first crewed mission to enter into a retrograde orbit around Earth's poles.
Article of the month Apollo Abort Guidance System The Apollo Abort Guidance System (AGS, also known as Abort Guidance Section) was a backup computer system providing an abort capability in the event of failure of the Lunar Module's primary guidance system (Apollo PGNCS) during descent, ascent or rendezvous. As an abort system, it did not support guidance for a lunar landing. The AGS was designed by TRW independently of the development of the Apollo Guidance Computer and PGNCS. It was the first navigation system to use a strapdown Inertial Measurement Unit rather than a gimbaled gyrostabilized IMU (as used by PGNCS). Although not as accurate as the gimbaled IMU, it provided satisfactory accuracy with the help of the optical telescope and rendezvous radar. It was also lighter and smaller in size.	Image of the month Falcon 9 Full Thrust Starting development in 2014, the Falcon 9 Full Thrust is a variant of the Falcon 9 that is the first orbital rocket to have a first stage successfully land vertically after launch. The stage shown here is from the April 2016 SpaceX CRS-8 mission, after landing on the autonomous spaceport drone ship Of Course I Still Love You.
