LASARSAT

LASARSAT (also written LASARsat) is a Czech scientific microsatellite assigned NORAD catalog identifier 62391 and international designator 2024-247Q. Launched in December 2024 aboard a SpaceX Falcon 9 rocket as part of the Bandwagon-2 rideshare mission, it occupies a low Earth orbit at roughly 440 kilometres altitude. The satellite represents a notable milestone in Central European space development, carrying forward the work of a Czech high school team into an operational orbital experiment with potential implications for the growing challenge of space debris management.

Mission and purpose

The origins of LASARSAT lie in an academic competition rather than a government program or established aerospace institution. The team behind the project, known as LASAR, won the Conrad Challenge, an internationally recognized STEM competition headquartered in Houston, Texas, that encourages young people to develop innovative solutions to real-world problems. Their winning concept centered on the use of high-power lasers as a tool for managing traffic in orbital space — an approach that, if proven viable, could offer a new avenue for addressing the accumulation of defunct hardware and debris in low Earth orbit.

The satellite's core purpose is experimental and demonstrative: to test whether laser-based systems can be practically applied from a small spacecraft platform to influence or track objects in the orbital environment. Space debris has become one of the central concerns of contemporary spaceflight. As the number of active satellites, rocket bodies, and fragmented objects in low Earth orbit has grown substantially over recent decades, the risk of collisions — and the cascading chain of further fragmentation they can cause, a scenario sometimes called the Kessler syndrome — has become a subject of serious scientific and regulatory attention. Technologies capable of actively managing orbital congestion are therefore of considerable interest to the broader space community.

The specific technical parameters of LASARSAT's laser payload, including power output, targeting methodology, and the scope of on-orbit testing planned, are not publicly recorded in available catalog data. Similarly, the identity of the satellite's operator and manufacturer have not been disclosed in official tracking records. What is documented is the mission's conceptual lineage: a student-originated idea, validated through international competition, translated into a functioning spacecraft.

Design and operator

LASARSAT conforms to the 1U CubeSat standard, one of the most widely adopted small-satellite form factors in the contemporary space industry. A 1U CubeSat measures 10 centimeters by 10 centimeters by approximately 11.3 centimeters in this case, yielding a total internal volume of roughly 1,000 cubic centimeters. This standardized form factor was originally developed in the late 1990s by professors at California Polytechnic State University and Stanford University as a means of lowering the barrier to entry for university and research satellite programs. It has since become the basis for thousands of orbital missions worldwide, ranging from educational demonstrations to operational Earth observation and communications payloads.

Within the constraints of the 1U envelope, the engineering challenge is significant: accommodating power systems, attitude control, communication hardware, and a scientific payload — in this case, a laser system — demands careful prioritization of mass and volume. The satellite's total mass is not publicly cataloged. Its country of origin is listed as the Czech Republic, reflecting the national affiliation of the team and project behind it.

The operator of LASARSAT is not identified in official tracking records, and the manufacturer similarly remains unspecified in publicly available data. This is not unusual for small satellite projects originating from academic or student teams, where institutional affiliations can be distributed across universities, research institutes, and private partners without a single entity assuming a publicly registered operational role.

Orbit and tracking

LASARSAT operates in low Earth orbit, the most densely populated region of near-Earth space, extending from roughly 200 to 2,000 kilometres above the planet's surface. As of the time of writing, the satellite remains in orbit and has not undergone atmospheric reentry.

Its current orbital parameters place the apogee — the highest point in its elliptical path — at approximately 445 kilometres and the perigee — the lowest point — at approximately 435 kilometres. The difference of roughly 10 kilometres between these two values indicates a nearly circular orbit, which is typical for small satellites in this altitude range. A circular orbit simplifies mission planning, produces relatively consistent ground coverage patterns, and reduces the variation in atmospheric drag that the spacecraft experiences over each pass.

The orbital inclination is 45.0 degrees relative to the equatorial plane. This inclination means the satellite's ground track sweeps across latitudes from 45 degrees north to 45 degrees south, covering a broad swath of Earth's surface that includes most of Europe, the continental United States, large portions of Asia, and significant areas of South America and Africa. For a Czech-originated mission, a 45-degree inclination conveniently ensures regular passes over the country of origin and across much of the technologically active world.

The orbital period — the time required to complete one full revolution of Earth — is 93.2 minutes, meaning LASARSAT completes roughly 15 to 16 orbits per day. At this altitude, atmospheric drag is low but not negligible; without periodic propulsive corrections, the orbit will gradually decay over time. Whether the satellite carries any propulsion capability is not recorded in available data.

LASARSAT was cataloged by the United States Space Force's 18th Space Control Squadron, which maintains the authoritative registry of Earth-orbiting objects under the NORAD catalog system. Its designator, 2024-247Q, encodes its launch year (2024), the sequential number of its launch event (247), and its position among the objects released from that launch (Q, indicating it was among multiple payloads on the Bandwagon-2 mission).

Significance and context

The LASARSAT mission is significant on several levels. At the national level, it represents a meaningful contribution from the Czech Republic to the experimental satellite sector. While the Czech Republic has a history of participation in European Space Agency programs and broader international space cooperation, entirely domestic small-satellite missions developed from student-originated projects are comparatively rare, and their successful placement in orbit is a consequential step for the country's space community.

At the thematic level, the mission addresses one of the most pressing long-term challenges in spaceflight. The problem of orbital debris is not merely academic: it has resulted in mandatory avoidance maneuvers for the International Space Station, informed new regulatory frameworks in multiple jurisdictions, and shaped the design requirements of commercial satellite constellations. Technological demonstrations — even those carried out on a 1U CubeSat platform with limited power and aperture — contribute data and proof-of-concept evidence that can inform larger-scale development efforts. If laser-based approaches to orbital traffic management prove measurable even in constrained form, the findings could support the case for more capable follow-on missions.

At the educational and inspirational level, the trajectory from a high school STEM competition win to an operational satellite in Earth orbit is an unusually complete arc. The Conrad Challenge, named for astronaut Charles "Pete" Conrad, is designed explicitly to connect student innovation to real-world application. LASARSAT's existence as a cataloged, orbiting spacecraft is a direct expression of that mission.

The current operational status of LASARSAT — whether it is actively transmitting, conducting its planned experiments, or operating in a limited capacity — is not confirmed in publicly available tracking records. The mission's outcomes, including any data returned from its laser payload experiments, have not been publicly detailed as of the information available at the time of writing.

How to spot it

LASARSAT is a 1U CubeSat, making it an extremely small object by any practical standard. At roughly 440 kilometres altitude, small CubeSats of this class are generally at or below the threshold of naked-eye visibility even under ideal dark-sky conditions, and are not reliably observable without optical aid. Its orbital inclination of 45.0 degrees means it does pass over a broad range of populated latitudes, including most of Europe, during each orbital cycle.

Observers wishing to attempt a sighting should consult up-to-date two-line element (TLE) data from the NORAD catalog using LASARSAT's identifier, 62391, to generate accurate pass predictions for their location. Passes occurring near local twilight — when the satellite is still illuminated by sunlight but the observer's sky is sufficiently dark — offer the best chance of detection. Even under favorable conditions, a 1U CubeSat at this altitude is a challenging target, and most observers should set expectations accordingly. Dedicated satellite-tracking tools and applications that incorporate current TLE data will provide the most reliable prediction of pass timing and sky position.
