Historians will look again on 2024 as a particular 12 months for spaceflight.
From SpaceX plucking an enormous rocket out of the sky to the primary privately funded spacewalk to the launch of a $5 billion mission to check an ice-covered ocean moon, this 12 months held many record-breaking achievements and advances that introduced humanity ever nearer to exploring the celebs.
Listed below are the highest 10 spaceflight tales from 2024.
1) SpaceX makes critical progress with its Starship megarocket
SpaceX made historical past when it caught the returning first-stage Tremendous Heavy booster from its 400-foot-tall (122 meters) Starship automobile immediately atop the launch mount, successfully furthering the chances of reusability within the spaceflight business.
The historic catch occurred throughout Starship’s fifth check flight on Oct. 13, and the street to get there was an extended one. After two check flights in 2023 — each which resulted in explosions — Starship’s Built-in Flight Check-3 (IFT-3) launched from SpaceX’s Starbase website in South Texas on the morning of March 14. The flight noticed the world’s strongest rocket attain orbital pace for the primary time.
Starship’s fourth flight, which launched on June 6, noticed additional enhancements, with the Tremendous Heavy booster making a gentle splashdown within the ocean. But it surely was Flight 5 that modified the sport for reusable rockets. After lifting off, Tremendous Heavy got here again to Starbase, the place it was caught in mid-air by the launch tower’s “chopstick” arms, an unprecedented maneuver that just about regarded like one thing out of a sci-fi movie.
SpaceX managed yet another Starship flight this 12 months, on Nov. 19. Whereas the corporate deliberate a repeat of the booster-catching feat, Tremendous Heavy as an alternative splashed down within the Gulf of Mexico, on account of a communications subject with the launch tower. This 12 months, SpaceX is keen for extra launches, with 25 Starship flights apparently deliberate for 2025.

2) Pioneering moon landings
This 12 months, we witnessed a pair of moon landings for the historical past books. On Feb. 15, Intuitive Machines’ hexagonal-cylinder-shaped lander — dubbed Odysseus (of Trojan Conflict fame) — launched on a SpaceX Falcon 9 rocket from NASA’s Kennedy Area Heart in Florida.
On the night of Feb. 22, the robotic lander touched down close to the moon’s south pole, making it the primary U.S. automobile to soft-land on the moon because the Apollo 17 mission in 1972. Odysseus was additionally the primary personal lander to ever obtain the feat. Onboard have been 12 payloads from NASA and business corporations, designed for a spread of duties on the moon’s floor.
Additionally this 12 months, Japan turned the fifth nation to contact down on the moon, doing so on Jan. 19. The Japan Aerospace Exploration Company (JAXA)’s robotic Sensible Lander for Investigating Moon (SLIM) probe managed to land inside 328 toes (100 meters) of JAXA’s deliberate website. Nicknamed “moon sniper,” SLIM’s exact touchdown was a major achievement for a lunar probe.
Regardless of the moon lander’s precision, SLIM landed upside-down on account of an engine failure throughout the descent. This created a problem for the probe’s photo voltaic panels, which have been unable to present energy to SLIM within the hours following the touchdown, as a result of they have been in a shadow. Though the lander did hibernate for durations, JAXA was in a position to make contact with SLIM till April, and so they lastly declared SLIM lifeless in August.
3) Boeing Starliner’s launches astronauts for the first time, and drama ensues
After some delays and scrapped launches, on June 5 Boeing’s Starliner capsule, designed as an astronaut taxi for NASA, launched from Cape Canaveral Area Power Station — the primary time people rode an Atlas rocket into area since Gordon Cooper’s Mercury-Atlas 9 mission in 1963.
The Starliner capsule launched with veteran NASA astronauts Barry “Butch” Wilmore and Sunita Williams, who’re each former U.S. Navy check pilots. This was additionally the primary time astronauts launched atop an Atlas V.
After one failed docking try, Starliner made it to the Worldwide Area Station (ISS) for a June 6 rendezvous, the place Wilmore and Williams have been scheduled to spend a few week working checks. However Starliner bumped into points with its thrusters, in addition to helium leaks that have been discovered after the capsule reached orbit.
NASA and Boeing prolonged the capsule’s ISS keep to look into the thruster subject. Finally, NASA determined towards having Williams and Wilmore return on Starliner, deeming it too dangerous. So, on Sept. 7, Starliner returned to Earth — touchdown at White Sands Area Harbor in New Mexico — with out the astronauts onboard, who nonetheless stay in orbit on the ISS.
Now, Williams and Wilmore are scheduled to return to earth no sooner than March 2025. The Starliner astronauts will come dwelling aboard a SpaceX Dragon capsule, the one which’s flying the corporate’s Crew-10 mission.
4) China’s Chang’e 6 mission brings samples dwelling from the moon’s far aspect
China’s robotic Chang’e 6 mission returned samples from the moon’s far aspect to Earth for the primary time ever this 12 months. Chang’e 6 launched on Could 3 from the Wenchang Area Launch Web site on the island of Hainan, positioned in southern China. Consisting of 4 components — a lunar orbiter, a lander, an ascender and an Earth-reentry module, the Chang’e 6 moon probe rode a Lengthy March 5 rocket into orbit.
On June 1, the Chang’e 6 lander touched down within the southern pocket of the unexplored Apollo crater within the South Pole-Aitken (SPA) basin to scoop and drill distinctive samples, which have been then transferred to the ascender and shot again up into the moon’s orbit. The following step was transferring the samples between the ascender and its orbital module. The rendezvous was profitable, and the two spacecraft docked on June 6, transferred the samples, after which separated once more.
Subsequent, the Chang’e 6 orbiter carried out its moon-to-Earth switch injection maneuver, so the 4.4 kilos (2 kilograms) of lunar samples might come again to Earth. The pattern capsule landed June 25 beneath parachutes in Inside Mongolia’s grasslands. After scientists carried out an preliminary research of the lunar samples Chang’e collected, they discovered the samples have a decrease density in comparison with different returned moon materials. Additional evaluation could possibly be essential to understanding extra concerning the moon’s origin and evolution.

5) SpaceX’s Polaris Daybreak personal astronaut mission
SpaceX made historical past with the Polaris Daybreak mission, which carried out the first-ever personal spacewalk. Backed by billionaire Jared Isaacman, the Polaris Program’s inaugural mission was initially scheduled for an Aug. 26 launch, which was delayed for extra preflight checks, after which delayed once more on account of unfavorable launch and return circumstances.
The mission lastly launched on Sept. 10 with the Crew Dragon capsule Resilience using a Falcon 9 rocket to succeed in an elliptical orbit round Earth. On the primary day of Polaris Daybreak’s five-day mission, Resilience reached a most altitude of 870 miles (1,401 kilometers) on its first day in area, larger than every other crewed Earth-orbiting spacecraft in historical past.
Except for Isaacman, the crew consisted of former U.S. Air Power lieutenant colonel Scott Poteet, the mission’s pilot, and SpaceX engineers Sarah Gillis and Anna Menon. Utilizing new SpaceX-designed spacesuits, Isaacman partially exited Resilience for a spacewalk on Sept. 12, adopted by Gillis a couple of minutes later.
The mission additionally accomplished science and engineering experiments, together with testing the web in area by communication with SpaceX’s Starlink community. On Sept. 15, the Polaris Daybreak crew capsule splashed down safely off Florida’s coast within the Gulf of Mexico. Through the mission, Gillis and Menon set the report for highest-flying girls, breaking the earlier report set by NASA astronaut Kathryn Sullivan throughout the STS-31 area shuttle mission in 1990.
6) Europa Clipper launches towards Jupiter’s intriguing ocean moon
NASA’s extremely anticipated Europa Clipper mission to the icy Jupiter ocean moon Europa launched Oct. 14, using a SpaceX Falcon Heavy rocket into the sky from Kennedy Area Heart in Florida. The $5 billion Europa Clipper represents years of labor and ambition to seek out out if the far-off moon might presumably help life.
Scientists assume {that a} liquid ocean of saltwater sits beneath Europa’s floor of ice. The solar-powered orbiter — which is without doubt one of the most refined spacecraft ever constructed — would be the first to analyze the habitability of an ocean world. After utilizing the gravity of Mars and Earth as a slingshot, Europa Clipper is focused to succeed in its vacation spot in 2030 after touring 1.8 billion miles (2.9 billion kilometers).
U.S. Poet Laureate Ada Limón wrote a poem, which is engraved within the poet’s handwriting on the spacecraft’s vault plate, to commemorate the event. In November, the orbiter efficiently deployed two scientific devices, the magnetometer’s growth and antennas for Europa Clipper’s radar instrument, which can stay prolonged during the journey to the Jupiter moon.
7) Mars helicopter Ingenuity says goodbye
The robotic helicopter landed on Mars with NASA’s Perseverance rover in February 2021, tasked with finishing 5 technology-demonstrating flights on the Crimson Planet. Seventy-two flights later, NASA lastly mentioned goodbye to Ingenuity on April 16 of this 12 months after its rotors sustained injury throughout a tough touchdown on the tough Martian terrain.
The 4-pound (1.8 kg) Ingenuity turned the primary plane to ever fly on the Crimson Planet, which is not any small feat contemplating Mars’s skinny ambiance. After it turned clear that the rotocopter would outlast 5 flights and its mission was prolonged, Ingenuity started serving as a scout for Perseverance.
Ingenuity proved that drones might fly in Mars’ ambiance, paving the way in which for potential future Martian plane. And though the helicopter is now not airborne, its avionics battery sensors stay useful. On Dec. 11, mission group members mentioned that Ingenuity can reside a second life as a sort of climate station by recording telemetry and taking photographs to retailer onboard.

8) ULA debuts its highly effective new Vulcan Centaur rocket
This 12 months noticed the primary two certification launches for United Launch Alliance’s (ULA) new Vulcan Centaur rocket, which is outfitted with a pair of BE-4 first-stage engines constructed by Blue Origin. With the purpose of changing ULA’s older Atlas and Delta rockets, Vulcan Heart made its first liftoff on Jan. 8 from Cape Canaveral Area Power Station. It carried a robotic lunar lander known as Peregrine, which was constructed by the Pittsburgh firm Astrobotic.
Whereas the launch went off with no hitch, Peregrine bumped into hassle on account of a defective helium strain management valve and by no means made it to the moon. The lunar lander wandered via area for greater than every week earlier than being steered again for a managed destruction in Earth’s ambiance.
Vulcan’s second certification launch, which occurred on Oct. 4, flew with no paying buyer. A little bit over 30 seconds after the rocket lifted off, a nozzle on considered one of Vulcan’s stable rocket boosters (SRBs) malfunctioned, inflicting the rocket to veer, earlier than the primary engines corrected the course and the rocket efficiently accomplished its flight. Subsequent, Vulcan will fly its first nationwide safety mission for the U.S. Area Power, which is at the moment scheduled for early 2025.
The brand new Ariane 6 heavy-lift rocket for the European Area Company (ESA) additionally launched for the primary time this 12 months, on July 9 from Europe’s Spaceport in Kourou, French Guiana. The Ariane 5 was retired a few 12 months earlier than the primary Ariane 6 launch, which left Europe unable to launch huge satellites on a rocket of its personal for a spell.
9) NASA cancels VIPER moon rover mission
NASA’s Volatiles Investigating Polar Exploration Rover (VIPER) was set to lift the bar for lunar exploration by showcasing what AI might do in area. The mission plan was for the robotic VIPER to land close to the moon’s south pool to seek for water and different sources to help the astronauts who will go to the moon’s floor throughout NASA’s Artemis missions.
Nonetheless, the science world was shocked when NASA cancelled the VIPER mission, a choice the company introduced on July 17. The choice to finish the VIPER challenge got here right down to budgetary considerations, though it had been profitable as much as the announcement. After spending round $450 million on this system, NASA selected to tug the plug. NASA anticipated to avoid wasting on improvement prices to the tune of $84 million by stopping the lunar lander challenge.
After the choice, NASA has regarded to see if different organizations are focused on utilizing the rover as-is. An alternative choice, NASA mentioned, is to reuse the lunar lander’s scientific devices and parts for different moon missions sooner or later. So, whereas VIPER’s authentic mission is gone, the lunar lander could reside on in another kind.
10) Oleg Kononenko breaks report for many time spent in area
Soviet and Russian cosmonauts have spent a very long time in area. They maintain all the prime 5 slots within the most-total-time-in-space checklist. And this 12 months, 60-year-old Valery Polyakov broke the report with 1,1110 days in area — by far probably the most whole time spent off Earth by any human in historical past. Polyakov additionally holds the report for many consecutive days in area. Within the mid-Nineties, he spent 438 days on Russia’s Mir area station.
The report for most individuals in Earth orbit at one time — 19 — was additionally set this 12 months, on Sept. 11, when three individuals launched on a Russian Soyuz capsule to the ISS. This broke the earlier report of 17 individuals in orbit, which was notched in Could 2023.
