An 18-Year-Old Built a 64-Gram Satellite, and NASA Actually Launched It into Space

Back in 2017, an 18-year-old pulled off something unusual: he built a satellite weighing just 64 grams, barely heavier than a handful of coins, then got it launched with NASA’s backing. Nearly ten years on, the project still comes up in conversations about lightweight space tech and student innovation.

The satellite, KalamSat, was developed by Rifath Shaarook for the Cubes in Space competition, organized by idoodlelearning with support from NASA and the Colorado Space Grant Consortium. The concept was straightforward: design a compact, lightweight device capable of withstanding the conditions of space.

A 64-gram Satellite That Left No Room For Error

The rules of the competition were tight. each project had to fit within a 4-centimeter (1.6-inch) cube and weigh no more than 64 grams. KalamSat, named after Abdul Kalam, the Indian aerospace scientist and statesman, met this limit precisely, a detail that already distinguished it from other entries.

Inside that compact structure were eight sensors designed to measure acceleration, rotation, and Earth’s magnetosphere, providing key data during the flight. As explained in a report published by Business Standard, Rifath Shaarook also pointed out that:

“We designed it completely from scratch,” he stated. “It will have a new kind of on-board computer and eight … built-in sensors to measure acceleration, rotation, and the magnetosphere of Earth.”

Smart Materials Doing The Heavy Lifting

What made the satellite so light comes down largely to its structure. It used a reinforced carbon fiber polymer, a material known for being both strong and lightweight, often seen in aerospace engineering.

The casing itself was made using 3D printing, which allowed for precise control over its shape and weight. As outlined in the project details, one of the main goals was to see how this ultra-light structure would hold up in space, especially in microgravity.

“This is the first time 3D printing technology has been used in space,” noted Shaarook, as quoted by the BBC. “We have made history”

A Quick Trip To Space, But Not Without Purpose

KalamSat launched on June 21, 2017, from NASA’s Wallops Flight Facility in Virginia. It did not enter orbit, as the mission followed a suborbital trajectory, meaning the satellite traveled into space before returning to Earth rather than circling the planet. This flight profile enabled a brief exposure to space conditions without sustained orbital insertion.

The full flight lasted approximately four hours, including about 12 minutes in microgravity. During this phase, the satellite remained operational, collecting data while its structural integrity was evaluated. Despite its small size, the mission represented a significant technical demonstration.
