The first crewed lunar flight in more than half a century, an intense commercial launch cadence and a high-profile satellite re-entry… It seems that 2026 is shaping up to be a milestone year for space exploration. Below are the space missions and developments worth tracking this year and a brief look at the recent NASA satellite crash to figure out how similar events can be reduced in the future.
Artemis II prepares for a historic crewed lunar flyby
Artemis II is set to be the marquee government mission of 2026. NASA plans a crewed lunar flyby mission that will send four astronauts aboard the Orion spacecraft on a roughly 10-day trip around the Moon and back. The agency has publicly targeted an April 2026 launch window, with April 1 often cited as the earliest possible launch date. At the same time, Artemis II launch date may be adjusted if required by the NASA team behind the project. The mission will test deep-space systems, life-support and mission operations before later lunar landing attempts.
Artemis II’s success would mark the first time humans travel beyond low Earth orbit since the Apollo era and is a critical step in NASA’s broader plan to return humans to the lunar surface later this decade.
SpaceX’s hectic launch cadence and Starship testing
SpaceX continues to dominate orbital activity in 2026. The company’s Falcon 9 fleet is maintaining a rapid launch tempo for Starlink constellation deployments and commercial payloads. Therefore, monitoring the SpaceX launch schedule is useful for anyone tracking the fast-moving commercial sector. Recent weeks have shown multiple Falcon 9 launches per month as SpaceX expands broadband coverage and services.
Some of the confirmed or scheduled missions include:
-
Starlink mission – March 17, 2026
-
Rocket: Falcon 9
-
Launch site: Cape Canaveral, Florida
-
-
Starlink mission – March 20, 2026
-
Rocket: Falcon 9
-
Launch site: Vandenberg Space Force Base, California
-
-
Additional Starlink launches – planned throughout late March and April
Most of these missions are designed to deploy batches of roughly 20–30 Starlink satellites into low Earth orbit to expand SpaceX’s global broadband network.
Meanwhile, SpaceX is also preparing a major test of its next Starship variant. The full-scale, heavy-lift Starship is central to long-term ambitions for lunar landers and crewed missions to Mars. Early April has been discussed publicly as the target window for a Version 3 test flight, subject to regulatory and technical clearances. Progress (and delays) with Starship will be closely watched because of the vehicle’s potential to reshape heavy-lift launch capability worldwide.
A busy year of lunar and robotic science missions
Beyond Artemis II, 2026 will see a raft of robotic lunar missions and scientific probes as multiple nations accelerate Moon-focused programs. International landers, orbiters and experiments are planned to study lunar geology, resources and the space environment — activity that collectively signals a renewed global focus on the Moon and preparatory work for sustainable exploration.
Experts have even described the year as a potential “year of the Moon” because of the number of missions targeting Earth’s natural satellite. These missions are part of a growing international race to establish a sustained presence on the Moon, particularly around the resource-rich lunar south pole. Researchers even urge the matter of the governance of resource-rich regions near the Moon’s south pole. Being the destination for the majority of lunar surface missions, this particular area of the Moon arguably requires safety zones, or marked buffer areas that separate lunar activities from one another, to limit both interference and stakeholders’ claims of exclusive access to valuable findings in the efficient use of lunar resources.
Expansion of human spaceflight programs
Human spaceflight is also broadening geographically. China’s Tiangong space station program continues crew rotations and science missions. Other national programs (India, Japan and European partnerships) are moving forward on astronaut training and demonstration flights. This diversification of crewed operations underscores a multi-polar era of space activity in which private and public actors both play major roles.
The Van Allen Probe A re-entry: lessons learned from what happened on March 11
One of the year’s high-profile incidents involving spacecraft occurred on March 11, 2026, when a long-operating research craft, Van Allen Probe A, re-entered Earth’s atmosphere and largely burned up on re-entry. The satellite, launched in 2012 to study Earth’s radiation belts, deorbited earlier than originally projected, after years of orbital decay that accelerated amid heightened solar activity. NASA tracked the event and confirmed the probe’s atmospheric entry and subsequent breakup over the Pacific. Authorities assessed the odds of debris causing harm as very low. No confirmed harm or injuries were reported in the wake of the accident.
Could this kind of “NASA satellite crash” be avoided in future missions?
Uncontrolled re-entries like the Van Allen Probe A case are generally the result of long-term orbital decay, often influenced by space weather (solar activity raises Earth’s upper atmosphere and increases drag), end-of-life planning, and the spacecraft’s fuel state. To reduce the risk of uncontrolled re-entries, mission planners can:
- Design and execute planned deorbit or graveyard-orbit maneuvers at end of life when fuel remains, ensuring controlled re-entry over uninhabited ocean areas.
- Implement passivation (venting residual propellants, deactivating energy sources) to lower the chance of on-orbit breakups.
- Include disposal margins and predictability in mission design, accounting for solar cycle extremes and long-term atmospheric density models.
- Improve space situational awareness and international data-sharing to refine re-entry predictions and give authorities time to warn affected regions.
Most modern large missions already include end-of-life disposal plans. Nevertheless, the Van Allen re-entry only underscores the role of solar activity and the value of conservative lifetime planning and tracking to minimize uncontrolled returns.
Why 2026 matters for spaceflight
Taken together, Artemis II, SpaceX’s ongoing launch cadence and Starship testing, expanded lunar science missions and diversified human spaceflight programs make 2026 a turning point. The year is notable for both symbolic milestones (returning astronauts beyond LEO) and for practical shifts in access to orbit driven by commercial providers.
