2023 was a monumental year for space exploration, with several key missions and events capturing the world’s attention. From the long-awaited launch of NASA’s Artemis 1 around the Moon to continued progress on SpaceX’s ambitious Starship prototype, this year marked major steps forward in humanity’s journey into the cosmos.
Artemis 1 Finally Takes Flight
After years of development and multiple scrubs, NASA finally launched its powerful new Space Launch System (SLS) rocket and Orion spacecraft on November 16 on a successful uncrewed test flight around the Moon. Known as Artemis 1, the mission lasted 25 days and travelled over 1.4 million miles, paving the way for future Artemis missions that will land astronauts on the lunar surface for the first time since 1972.
The launch signifies a major milestone for NASA’s Artemis program, which aims to establish a sustainable presence on the Moon and use it as a stepping stone for eventual human exploration of Mars.
“With this mission, not only did we retire a lot of risk in advance for crewed flight, but we validated all the tools, all the models, all the analysis, all the hardware that will allow us to ultimately go back to the moon with crew reliably and safely,” said Mike Sarafin, Artemis 1 mission manager.
While Orion did not land on the Moon this time, the data gathered from this successful test flight will enable that, along with key life support testing and rehearsing operations in deep space.
SpaceX Inches Closer to Starship Orbital Flight
SpaceX continued to push ahead with its audacious Starship program in 2023. While still awaiting regulatory approval for an inaugural orbital test flight, the private space company carried out several high-altitude test launches of Starship prototypes from its Texas test facilities.
The upper stages reached altitudes of over 6 miles (10 km), significantly higher than any previous tests, before returning to land upright. While there were still explosions on some launches, SpaceX is clearly edging closer to the first orbital launch attempt of the 394-foot-tall rocket system.
CEO Elon Musk says the fully reusable Starship vehicle represents the company’s flagship project, the aim being to use it to enable human exploration and settlement of Mars while also providing satellite launches closer to home.
“I feel like this is something that could really move the needle,” Musk stated after one successful high-altitude flight. “It could really reignite people’s passion for space exploration.”
Once operational, Starship will be the most powerful rocket ever built, capable of lifting over 220,000 pounds (100 metric tonnes) to low Earth orbit. That’s more than double the lift capacity of NASA’s SLS rocket used on Artemis 1.
Asteroid Samples Successfully Returned to Earth
Two daring sample return missions – NASA’s OSIRIS-REx and JAXA’s Hayabusa2 – triumphed in 2023 by delivering pristine asteroid material to eager scientists back on Earth.
After briefly touching down on asteroid Bennu in 2020, NASA’s spacecraft arrived home on September 24, dropping a protective capsule over Utah that contained at least 2 ounces of cosmic rubble – the largest sample from space since the Apollo era.
“This successful OSIRIS-REx mission achieved a technological marvel: delivering the sample of an ancient asteroid here to Earth,” said Thomas Zurbuchen, NASA’s science mission director.
Researchers will spend years analyzing the rocks and dust to unravel secrets of the solar system’s earliest stages.
Meanwhile, Japan’s Hayabusa2 mission capped an epic 7-year journey across the solar system in June when its return capsule brought back soil samples from asteroid Ryugu, over 190 million miles away. The 5.4 grams of subsurface material could provide clues to the origin of life’s building blocks.
These feats prove the value of difficult sample return missions, setting the stage for more ambitious efforts in 2023 and beyond like NASA’s Mars Sample Return campaign.
India and Russia Revive Lunar Ambitions
Both India and Russia signaled intentions in 2023 to revive lunar landing missions over a decade after facing setbacks.
India’s space agency ISRO unveiled ambitious plans for the nation’s third Moon mission, Chandrayaan-3, which will attempt to soft-land on the lunar surface after the previous effort crashed in 2019. Officials say the new version has better hazard avoidance to position the lander safely amid rugged terrain.
News reports suggest a launch could come in mid-2023, as India looks to gain ground in the active global push for lunar exploration alongside NASA, China, and others.
Russia likewise wants to reclaim lost lunar glory after failures and budget cuts over the past years led to launch delays. Government sources revealed the revival of Luna 25 – an ambitious mission to land near the Moon’s south pole and drill for ice samples. It would be Russia’s first Moon landing since 1976.
“The level of exploration of the moon by our country is extremely insufficient and requires intensification,” said high-ranking space official Sergei Saveliev on Russian state TV.
Officials now state Luna 25 could blast off in late 2023 or 2024.
Private Moon Missions Take Shape
Aside from national space agencies, private companies also publicized major 2023 plans to deliver scientific payloads and even land rovers across the lunar surface.
After debuting launch capabilities last year, Firefly Aerospace’s Blue Ghost lander aims to deliver 10 NASA-sponsored experiments investigating lunar geology in a mission launching by September 2023.
Houston-based Intuitive Machines also plans two Moon cargo flights carrying over a dozen payloads such as resource mapping tools, dust analyzers, and a small Nova-C lander built to survive lunar night temperatures. Their first launch could come in early 2023.
These initial forays will help lay the groundwork for more complex private-public partnerships pursuing lunar bases and mining in the future.
Webb Space Telescope Rewrites Cosmic History
While the year held many events advancing human spaceflight, arguably the top space story of 2023 was the torrent of discoveries unleashed by the newly operational James Webb Space Telescope.
In its first year of science operations, NASA’s $10 billion flagship observatory rewrote the history books across a range of areas from exoplanet atmospheres to galaxy formation and cosmology. Findings suggest two galaxies existed just 300 million years after the Big Bang – fully forming far quicker than theorized.
Researchers say the revelations upend previous theories and will lead to Nobel-worthy insights about the origins of the universe. Most tantalizingly, Webb’s extremely sensitive infrared vision has spotted features in the atmospheres of alien worlds that could allow biosignature gases like oxygen and methane to be detected in the future. The potential for discovering extraterrestrial life has never been higher.
“It’s almost like a dream device that you wouldn’t have even thought to ask for,” said Garth Illingworth, an astronomer at the University of California. “It will continue to provide exciting and completely unexpected results.”
Indeed, many speculate Webb’s vision will spark as great a leap in understanding the mysteries of the universe as when Galileo first used a telescope to gaze at the heavens over 400 years ago.
Outlook: Momentum Builds Towards Mars and Stars
With the triumphs of Artemis 1, asteroid sample returns, private Moon missions and the Webb telescope’s transformational observations, 2023 undoubtedly goes down as a banner year advancing humanity’s reach into space.
And the momentum seems set to continue building well beyond this year. The table below shows some highly anticipated missions and milestones coming soon:
| Year | Mission or Milestone | Significance |
|---|---|---|
| 2024 | 2nd SLS/Orion Artemis Flight | 4 astronauts in lunar orbit |
| 2025 | 1st Commercial Modules of Lunar Gateway | Base to stage surface missions |
| 2026 | Sample Return from Mars | Hunt for ancient life on Mars |
| 2027 | Europa Clipper at Jupiter | Study subsurface ocean world |
| 2028 | Starship Orbital Refuel Test | Key step before passenger flights |
| 2030s | Starship Mission to Mars | Up to 100 colonists to Red Planet |
In many ways, the 2030s and beyond promise even greater leaps as NASA returns boots to lunar soil, expands infrastructure for sustained research and economic activity in cislunar space, and pushes onwards to land humans on Mars by the late 2030s.
Meanwhile SpaceX continues working towards Musk’s vision of establishing the first self-sustaining city on Mars in our lifetimes. Their 2022 Starship update stated:
“The overarching goal of SpaceX has been to establish humanity as a multiplanetary species and spacefaring civilization – this is the next step towards that goal.”
After the landmarks of 2023, spectacular voyages to alien worlds once only dreamed of may finally approach reality in coming years.
So while it’s worth celebrating the events covered here that captivated millions and unleashed profound discoveries in the past year alone, in many ways this is just the beginning of the next giant leap for humankind. As our knowledge expands and access to space scales exponentially thanks to new rockets like SLS, spacecraft such as Orion and Starship, we stand at the precipice of an exciting new era of space age exploration.
