Most CubeSats weigh lower than a bowling ball and a few are sufficiently small to carry in your hand. But the impact of those instruments on space research is gigantic. CubeSats – small, agile and low-cost satellites – are revolutionizing the best way scientists explore the cosmos.
A Standard size CubeSat is tiny, about 4 kilos (about 2 kilograms). Some are larger, perhaps 4 times the usual size, but others weigh not more than a pound.
As Professor of electrical engineering and data technology Anyone working with latest space technologies can let you know that CubeSats are a neater and much cheaper solution to reach other worlds.
Rather than carrying many instruments with quite a lot of purposes, these Lilliputian-sized satellites typically deal with a single, specific scientific goal – be it discovering exoplanets or measuring the dimensions of an asteroid. They are reasonably priced across the space industry, even for small startups, private firms and university labs.
Tiny satellites, big benefits
The benefits of CubeSats over larger satellites are significant. CubeSats are cheaper to develop and test. The money and time saved means more frequent and varied operations with lower risk. That alone increases the pace of discovery and space exploration.
CubeSats don’t travel under their very own power. Instead, they let you’re taking them with you; They turn into a part of the payload of a bigger spacecraft. Filled into containers, they’re propelled into space by a spring mechanism attached to their dispensers. Once they're in space, they activate. CubeSats typically complete their missions by burning up upon entering the atmosphere after their orbits slowly decay.
Case in point: a team of scholars at Brown University built a CubeSat under 18 months for lower than $10,000. The satellite is in regards to the size of a loaf of bread and was designed to review the growing problem Space junkWas deployed from a SpaceX rocket in May 2022.
Smaller size, single purpose
Of course, sending a satellite into space is nothing latest. The Soviet Union launched Sputnik 1 put into orbit in 1957. Today, approx There are 10,000 energetic satellitesand just about all are energetic in communications, navigation, military defense, technological development or earth research. Only just a few – lower than 3% – explore space.
That's changing now. Satellites large and small are quickly becoming the backbone of space exploration. These spacecraft can now travel long distances to review planets and stars, places where human exploration or robotic landings are costly, dangerous or just inconceivable with current technology.
But the prices of constructing and launching traditional satellites are significant. NASA Lunar reconnaissance orbiterLaunched in 2009, the minivan is in regards to the size of a minivan and costs nearly $600 million. The Mars reconnaissance orbiterwith a wingspan the length of a college bus, cost greater than $700 million. The The European Space Agency's solar orbiterA 1,800 kilogram probe to explore the sun cost $1.5 billion. And the Europe Clipper – so long as a basketball court and scheduled to launch to Jupiter's moon Europa in October 2024 – will ultimately cost $5 billion.
These satellites are relatively large and surprisingly complex vulnerable to possible failuresa not unusual event. In an fast, years of labor and tons of of thousands and thousands of dollars may very well be lost in space.

Exploration of the Moon, Mars and the Milky Way
Because they’re so small, CubeSats could be released in large numbers in a single launch, further reducing costs. By using them in batches – so-called constellations – several devices can observe the identical phenomena.
For example, as a part of the Artemis I mission in November 2022 NASA has launched 10 CubeSats. The satellites are actually attempting to discover and map water on the moon. These findings are critical not only to the upcoming Artemis missions, but in addition to the hassle to keep up a sustained human presence on the lunar surface. The CubeSats cost $13 million.
The MarCO CubeSats – two of them – accompanied NASA's Insight Lander to Mars in 2018. They served as a real-time communications relay back to Earth during Insight's entry, descent and landing on the Martian surface. As a bonus, she captured images of the planet with wide-angle cameras. They cost about $20 million.
CubeSats have also studied nearby stars and exoplanets, that are worlds outside the solar system. In 2017 NASA's Jet Propulsion Laboratory used ASTERIAa CubeSat that observed 55 Cancri ealso referred to as Janssen, an exoplanet eight times larger than Earth orbiting a star 41 light-years away from us. By reconfirming the existence of this distant world, ASTERIA became the smallest space instrument ever to find an exoplanet.
Two other notable CubeSat space missions are underway: HERAwhich is scheduled to launch in October 2024, will provide this European Space Agency first space CubeSats visit Didymos asteroid systemwhich orbits within the asteroid belt between Mars and Jupiter.
And the M-Argo satellitewhich is scheduled to be introduced in 2025, will investigate this Shape, mass and surface minerals of a soon-to-be-named asteroid. At the dimensions of a suitcase, M-Argo will probably be the smallest CubeSat able to carrying out its own independent mission in interplanetary space.
The rapid progress and significant investments already made in CubeSat missions could help make humans a multiplanetary species. But this journey will probably be long – and is dependent upon the subsequent generation of scientists making this dream a reality.
