Overview

Astronomy and Astrophysics

On 1 July, European Space Agency's (ESA) Euclid satellite was launched towards Sun-Earth L2 point by a Falcon 9 rocket. The satellite observes distant galaxies to study dark matter and dark energy in our Universe.

Exploration of the Solar System

On April 14, ESA launched the Jupiter Icy Moons Explorer (JUICE) spacecraft to explore Jupiter and its large ice-covered moons following an eight-year transit.[1]

ISRO launched its third lunar mission Chandrayaan-3 on 14 July 2023 at 9:05 UTC;[2] it consists of lander, rover and a propulsion module,[3] and is supposed to land on the south pole of the Moon on 23 August 2023.

Russian lunar lander Luna 25 was launched on August 10, 2023, 23:10 UTC, atop a Soyuz-2.1b rocket from the Vostochny Cosmodrome.[4] It is the first Russian attempt to land a spacecraft on the Moon since the Soviet lander Luna 24 in 1974.

The OSIRIS-REx mission will return to Earth on 24 September with samples collected from asteroid Bennu.[5]

NASA plans to launch the Psyche spacecraft, an orbiter mission that will explore the origin of planetary cores by studying the metallic asteroid 16 Psyche, in October 2023 on a Falcon Heavy launch vehicle.

Human spaceflight

A new record for the number of people in space at once was reached on 25 May 2023. 20 people were in space simultaneously, with eleven people aboard the ISS, three on Tiangong, and six on SpaceShipTwo.[6] 5 days later on 30 May, the record for the number of people in orbit simultaneously was broken as well, with 17 people in orbit at once; 6 people on Tiangong from Shenzhou 15 and 16, 7 people from Expedition 69 on the ISS as well 4 crew members from Axiom-2 also on the ISS.[7][6]

Space tourism

Axiom Mission 2 private crew mission to the International Space Station was launched on 21 May 2023 on a SpaceX Falcon 9. The mission ended with successful return of the crew to Earth on 31 May 2023.

Virgin Galactic Unity 25 mission took place 25 May 2023. This was the first mission for Virgin Galactic's suborbital spaceplane VSS Unity since 2021. On 29 June 2023, Virgin Galactic flew their first commercial suborbital spaceflight mission, Galactic 01, with their suborbital spaceplane VSS Unity. Onboard Unity were three employees of the company and three passengers (whose flight had been paid from outside the company) from the Italian Air Force and Italy’s National Research Council.[8] On 10 August Virgin Galactic flew their Galactic 02 mission, the first VSS Unity flight carrying a space tourist.

SpaceX plans to fly Polaris Dawn in September, a Crew Dragon mission including the first commercial spacewalk.

Rocket innovation

The maiden flight of United Launch Alliance's Vulcan Centaur[9] is planned for 2023, along with other smaller rockets.

On January 10, ABL Space Systems' RS1 had its debut flight, but failed to reach orbit.[10]

On March 7, JAXA/MHI H3's maiden flight was terminated in-flight due to failure to ignite the second stage, resulting in the loss of the ALOS-3 land observation satellite.[11]

On March 23, Relativity Space's Terran 1 had its debut flight. The flight goal, which was to demonstrate the viability of 3D printing for major structural components of a rocket, was achieved when Terran 1 passed max q and continued to perform nominally. However, after stage separation, the second stage failed to ignite, ending the mission.[12] Following the failed launch, Relativity retired the rocket in favor of developing the much larger, reusable Terran R vehicle.[13]

On April 2, Space Pioneer's Tianlong-2 had its debut flight, and successfully reached orbit. It was the first successful launch of a Chinese privately-funded liquid-fueled rocket. Space Pioneer is the first private company to reach orbit on its first attempt using a fully liquid fueled rocket.[14]

On April 20, SpaceX's Starship had its first test flight,[15] aiming to complete about three-quarters of an orbit and landing in the Pacific Ocean northwest of Kauai.[16] Some engines on the booster failed during the flight and the flight termination system was triggered, ending the flight before stage separation.

On April 22, Evolution Space completed its first space flight test with the Gold Chain Cowboy solid-fueled rocket.[17]

Virgin Orbit declared Chapter 11 bankruptcy on April 4, 2023.[18] The following dissolution of the company led to the retirement of LauncherOne rocket, with the unsuccessful launch of 9 January 2023 remaining the last flight of LauncherOne.

On May 30, the North Korean Chollima-1 made its first orbital launch attempt, carrying the military reconnaissance satellite Malligyong-1.[19] However, the launch failed to achieve orbit when the second stage ignited too early in the mission.[20] The launch vehicle crashed into the Yellow Sea.[21]

On July 5, Arianespace's Ariane 5 rocket flew its final mission.

On July 12, LandSpace's Zhuque-2 rocket, in its second flight, became the world's first methane-fuelled rocket to successfully reach orbit.[22]

On August 2, Antares 230+ rocket flew its final mission.

Satellite technology

On January 27, ESA reported the successful demonstration of a braking sail-based satellite deorbiter, Template:Tooltip, which could be used by space debris mitigation measures.[23][24]

In April, Chinese media first reported on tests of flexible organic solar cells on balloons in the 35 km stratosphere.[25][26]

On 29 July a Falcon Heavy rocket launched the Jupiter-3 (EchoStar-24)[27] communications satellite to geosynchronous orbit. With a mass of over 9 tonnes, EchoStar's Jupiter-3 is the heaviest geostationary satellite ever launched.[28]

On 1 June, Caltech reported the first successful demonstration of solar energy from space via its SSPD-1 spacecraft.[29][30]

20 January 2023
13:14
7 hours 21 minutes 20:35 Expedition 68
ISS Quest
Template:Flagicon Koichi Wakata
Template:Flagicon Nicole Mann
First spacewalk of 2023 to finish installation of the IROSA mounting brackets on the starboard side of the station. Wakata and Mann installed cables on the 1B Array at the S6 truss, which was not completed on the last spacewalk, tightened bolts and installed a terminator on a cable along with its connected jumper on the SSDCDC converter box to isolate the 1B array until the IROSA solar arrays are installed following the arrival of SpaceX CRS-28 in June. They also assembled and installed the IROSA mounting bracket onto the 1A array, which was also left incomplete on the last spacewalk. Wakata and Mann were unable to secure the final strut on the 1A solar array because of debris in the guide track of the mounting pad and only one of the jumpers was installed. The astronauts returned the strut to the Quest Airlock and will use special tools to clean the tracks before it is remounted on the next spacewalk. They were also unable to connect the cables for 1A due to time constraints. NASA astronaut Zena Cardman was Ground IV, assisted by JAXA astronaut Akihiko Hoshide, who was the Capcom for the astronauts inside the ISS during the spacewalk.[39][40][41]

6 hours 41 minutes 19:26 Expedition 68
ISS Quest
Template:Flagicon Nicole Mann
Template:Flagicon Koichi Wakata
Final spacewalk to install the mounting brackets for the 1A solar array in preparation for the delivery of IROSA on SpaceX CRS-28. Tasks included installing the final strut, securing the bolts on the 1A solar array, relocating foot restraints that were left on P6 inboard, and routing cables. NASA astronaut Zena Cardman was Ground IV.[42][43]
9 February 2023
9:10
7 hours 6 minutes 16:16 Shenzhou 15
TSS Wentian airlock
Template:Flagicon Fei Junlong
Template:Flagicon Zhang Lu
They completed a series of tasks, including installing the fourth external pump (Z01-04) on the Mengtian lab module and other tasks related to Mengtian's payload airlock, which allows astronauts to deploy science payloads and small satellites using the station's robotic arms. After successfully completing the installation and commissioning of the extended pump set in the Mengtian experimental cabin, Fei Junlong needs to transfer to the core cabin of Tianhe, remove the foot stopper in the tool box outside the node, and then return to the Mengtian experimental cabin, and install it in the designated location for the second time out of the cabin to install large equipment. For the first time, Fei Junlong held a large-scale foot stopper and an external operating platform to carry out a large-scale transfer, which put forward higher requirements for the safety of the task.[44] It is China's longest spacewalk to date.[45]

TSS Wentian airlock

Template:Flagicon Fei Junlong
Template:Flagicon Zhang Lu
Fei Junlong and Zhang Lu went out of the cabin again to perform tasks such as the installation of external equipment on the space station. After leaving the cabin, Fei Junlong and Zhang Lu first autonomously transferred to the operating point with the help of the handrail outside the cabin. During the crawling process, Fei Junlong had to take off the two safety rope hooks of the previous handrail and hang them on the next handrail every time he moved a handrail. Repeatedly picking and hanging the hooks was a small challenge and not good for the strength of the astronaut’s upper limbs.

The equipment that Fei Junlong and Zhang Lu are going to install for the second time out of the cabin has about 20 plugs, and these plugs have protective covers.[46] When installing, you need to pull out the protective covers before inserting the plugs. Do a power test. Other tasks were to dump trash bags during spacewalk.[47]

Template:Flagicon Fei Junlong
Template:Flagicon Zhang Lu
Fei Junlong and Zhang Lu partnered again to perform the third out-of-cabin activity and complete the task of installing and connecting cables across the cabin. There are more than 40 plugs at both ends of the cross-cabin cable, and the work intensity and difficulty are greater than last time.

Fei Junlong and Zhang Lu successfully completed this mission in a way that they had not trained before.[48] Other tasks were to dump trash bags during spacewalk.[49]

Template:Flagicon Zhang Lu
During the fourth spacewalk, the three astronauts of the Shenzhou 15 crew worked closely together inside and outside the cabin, and successfully completed the installation of the fifth extended pump (Z02-01) set outside the Mengtian, the installation and connection of cross-cabin cables, and the external load exposure platform. The installation of support rods and other tasks laid the foundation for the subsequent large-scale extravehicular science and technology experiments. Other tasks were to dump trash bags during spacewalk.[50]

7 hours 55 minutes 09:35 Expedition 69

ISS Poisk

Template:Flagicon Sergey Prokopyev
Template:Flagicon Dmitry Petelin
Ninth in a series of spacewalks to outfit Nauka and to prepare ERA for operations. The spacewalkers used ERA to pick up the radiator with the arm where it was relocated at the end of the spacewalk. They closed valves on the nitrogen jumpers, removed covers over the nitrogen jumpers, disconnected the radiator heater cable and capped it, removed bolts and launch restraints, and transferred the radiator over to Nauka and installed it into a socket on the forward face where it will be deployed at the end of EVA 4. As part of get-ahead tasks, they will prepare the airlock for transfer to Nauka on the next spacewalk and stowed the ERA adapter on the airlock. Because of time and issues with matting the radiator the task to jettison the covers was moved to the next spacewalk. This was the longest spacewalk of this expedition and a critical one to get the lab activated.[51]
28 April
13:11
7 hours 1 minute 20:12 Expedition 68
ISS Quest
Template:Flagicon Stephen Bowen
Template:Flagicon Sultan Al Neyadi
Bowen and Al Neyadi, who became the first Arab astronaut to perform a spacewalk, finished routing cables and secured the struts with MLI at the 1B and 1A solar arrays in preparation for the arrival of the IROSA arrays in June. The primary task to retrieve the Space to Ground Antenna (SASA) was deferred to the next spacewalk because a stuck bolt on the electronics box prevented the antenna from being released from the FRAM. NASA Astronaut Anne McClain was Ground IV CAPCOM.[52][53][54]
4 May
20:00
7 hours 11 minutes 03:11 Expedition 69

ISS Poisk

Template:Flagicon Sergey Prokopyev
Template:Flagicon Dmitry Petelin
Tenth in a series of spacewalks to outfit Nauka and to prepare ERA for operations. The spacewalkers removed bolts, removed covers, disconnected cables, and used ERA to transfer the airlock over to Nauka where it was installed on the forward facing port. Once the airlock was installed they mated cables and jettisoned their trash which included hardware and covers from the previous spacewalks and this spacewalk. Spacewalk faced a delay when ERA entered an uncontrolled roll placing the airlock out of alignment. Prokopyev and Petelin improvised with a little elbow grease and got the airlock rotated into the correct position and got it latched in place. Spacewalk faced another delay when tape was found on the electrical connectors requiring Prokopyev to cut it before the cables were connected.[55][56][57][58]
12 May
