Historians will look again on 2024 as a particular yr 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 review an ice-covered ocean moon, this yr held many record-breaking achievements and advances that introduced humanity ever nearer to exploring the celebs.
Here 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 Super Heavy booster from its 400-foot-tall (122 meters) Starship automobile instantly atop the launch mount, successfully furthering the chances of reusability within the spaceflight trade.
The historic catch occurred throughout Starship’s fifth take a look at flight on Oct. 13, and the street to get there was a protracted one. After two take a look at flights in 2023 — each which resulted in explosions — Starship’s Integrated Flight Test-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 velocity for the primary time.
Starship’s fourth flight, which launched on June 6, noticed additional enhancements, with the Super Heavy booster making a mushy splashdown within the ocean. But it was Flight 5 that modified the sport for reusable rockets. After lifting off, Super 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 seemed like one thing out of a sci-fi movie.
SpaceX managed yet another Starship flight this yr, on Nov. 19. While the corporate deliberate a repeat of the booster-catching feat, Super Heavy as an alternative splashed down within the Gulf of Mexico, on account of a communications difficulty with the launch tower. This yr, SpaceX is raring for extra launches, with 25 Starship flights apparently deliberate for 2025.

2) Pioneering moon landings
This yr, 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 War fame) — launched on a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center 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 variety of duties on the moon’s floor.
Also this yr, Japan grew to become the fifth nation to contact down on the moon, doing so on Jan. 19. The Japan Aerospace Exploration Agency (JAXA)’s robotic Smart 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.
Despite the moon lander’s precision, SLIM landed upside-down on account of an engine failure through the descent. This created a problem for the probe’s photo voltaic panels, which have been unable to provide energy to SLIM within the hours following the touchdown, as a result of they have been in a shadow. Although the lander did hibernate for durations, JAXA was in a position to make contact with SLIM till April, they usually 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 Space Force 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 take a look at pilots. This was additionally the primary time astronauts launched atop an Atlas V.
After one failed docking try, Starliner made it to the International Space Station (ISS) for a June 6 rendezvous, the place Wilmore and Williams have been scheduled to spend a couple of week operating assessments. But 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 difficulty. Eventually, NASA determined in opposition to having Williams and Wilmore return on Starliner, deeming it too dangerous. So, on Sept. 7, Starliner returned to Earth — touchdown at White Sands Space 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 house 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 house 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 yr. Chang’e 6 launched on May 3 from the Wenchang Space Launch Site on the island of Hainan, positioned in southern China. Consisting of 4 parts — a lunar orbiter, a lander, an ascender and an Earth-reentry module, the Chang’e 6 moon probe rode a Long 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 subsequent 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.
Next, 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 below parachutes in Inner Mongolia’s grasslands. After scientists carried out an preliminary examine of the lunar samples Chang’e collected, they discovered the samples have a decrease density in comparison with different returned moon materials. Further evaluation might be vital to understanding extra in regards to the moon’s origin and evolution.

5) SpaceX’s Polaris Dawn personal astronaut mission
SpaceX made historical past with the Polaris Dawn 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 added preflight checks, after which delayed once more on account of unfavorable launch and return situations.
The mission lastly launched on Sept. 10 with the Crew Dragon capsule Resilience driving a Falcon 9 rocket to succeed in an elliptical orbit round Earth. On the primary day of Polaris Dawn’s five-day mission, Resilience reached a most altitude of 870 miles (1,401 kilometers) on its first day in area, greater than another crewed Earth-orbiting spacecraft in historical past.
Aside from Isaacman, the crew consisted of former U.S. Air Force lieutenant colonel Scott Poteet, the mission’s pilot, and SpaceX engineers Sarah Gillis and Anna Menon. Using 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 Dawn crew capsule splashed down safely off Florida’s coast within the Gulf of Mexico. During the mission, Gillis and Menon set the document for highest-flying girls, breaking the earlier document set by NASA astronaut Kathryn Sullivan through 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, driving a SpaceX Falcon Heavy rocket into the sky from Kennedy Space Center in Florida. The $5 billion Europa Clipper represents years of labor and ambition to search 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 likely 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 is able to stay prolonged throughout 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 Red Planet. Seventy-two flights later, NASA lastly stated goodbye to Ingenuity on April 16 of this yr after its rotors sustained harm throughout a tough touchdown on the tough Martian terrain.
The 4-pound (1.8 kg) Ingenuity grew to become the primary plane to ever fly on the Red Planet, which is not any small feat contemplating Mars’s skinny ambiance. After it grew to become 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 best way for potential future Martian plane. And despite the fact that the helicopter is not airborne, its avionics battery sensors stay useful. On Dec. 11, mission crew members stated that Ingenuity can stay a second life as a form of climate station by recording telemetry and taking pictures to retailer onboard.

8) ULA debuts its highly effective new Vulcan Centaur rocket
This yr 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 aim of changing ULA’s older Atlas and Delta rockets, Vulcan Center made its first liftoff on Jan. 8 from Cape Canaveral Space Force Station. It carried a robotic lunar lander known as Peregrine, which was constructed by the Pittsburgh firm Astrobotic.
While the launch went off with out a hitch, Peregrine bumped into bother on account of a defective helium strain management valve and by no means made it to the moon. The lunar lander wandered by area for greater than per 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 out a paying buyer. Somewhat over 30 seconds after the rocket lifted off, a nozzle on one among Vulcan’s strong rocket boosters (SRBs) malfunctioned, inflicting the rocket to veer, earlier than the primary engines corrected the course and the rocket efficiently accomplished its flight. Next, Vulcan will fly its first nationwide safety mission for the U.S. Space Force, which is at the moment scheduled for early 2025.
The new Ariane 6 heavy-lift rocket for the European Space Agency (ESA) additionally launched for the primary time this yr, on July 9 from Europe’s Spaceport in Kourou, French Guiana. The Ariane 5 was retired a couple of yr earlier than the primary Ariane 6 launch, which left Europe unable to launch large 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 assets to help the astronauts who will go to the moon’s floor throughout NASA’s Artemis missions.
However, the science world was shocked when NASA cancelled the VIPER mission, a call the company introduced on July 17. The choice to finish the VIPER mission got here right down to budgetary issues, despite the fact that it had been profitable as much as the announcement. After spending round $450 million on this system, NASA selected to drag the plug. NASA anticipated to avoid wasting on growth prices to the tune of $84 million by stopping the lunar lander mission.
After the choice, NASA has seemed to see if different organizations are occupied with utilizing the rover as-is. Another possibility, NASA stated, 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 stay on in another type.
10) Oleg Kononenko breaks document 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 listing. And this yr, 60-year-old Valery Polyakov broke the document with 1,1110 days in area — by far essentially the most complete time spent off Earth by any human in historical past. Polyakov additionally holds the document for many consecutive days in area. In the mid-Nineteen Nineties, he spent 438 days on Russia’s Mir area station.
The document for most individuals in Earth orbit at one time — 19 — was additionally set this yr, on Sept. 11, when three folks launched on a Russian Soyuz capsule to the ISS. This broke the earlier document of 17 folks in orbit, which was notched in May 2023.
