The SLS will also be carrying a secondary payload, a series of shoeboxes sized satellites that it will jettison as it travels towards the moon. Though the SLS can host 17 of these diminutive science experiments, the Artemis 1 payload will be comprised of 10 units. Cubesats are remarkable for their efficiency, low cost, and compatibility with larger payloads. Though they are usually restricted in mass to between 2.2 and 22 lbs (1 and 10 kilograms), cubesats are usually measured and classified by 'units' (U) with each unit representing a cube of 10 centimeters (3.93 inches) each side. The majority...

The first two tiny satellites to ever go interplanetary have fallen silent in deep space for some unknown reason, and it’s likely we may never hear from them again. But for NASA, which launched the probes last year, this loss of communication isn’t considered a failure. Before the pair went quiet, these vehicles demonstrated that tiny satellites could become critical tools for exploring other worlds deep within our Solar System. The silent satellites are the two MarCO probes — nicknamed EVE and WALL-E from Pixar’s sci-fi movie — which flew to Mars along with NASA’s InSight lander last year. Both...

In May, NASA announced that it would invest funds in 10 mission concepts involving small satellites called cubesats. Recently, the agency released more details about one of those concepts — the Bi-sat Observations of the Lunar Atmosphere above Swirls (BOLAS) mission concept. The mission would involve two small satellites, each about the size of a shoebox, connected vertically above the lunar surface by a long, thin tether, like some kind of miniature sky crane. The cubesat at one end of the tether would orbit the moon at an altitude of about 118 miles (189 km), which would place the second...

Using carbon nanotubes, the Goddard team – which is led by Dr. Theodor Kostiuk of NASA’s Planetary Systems Laboratory and Solar System Exploration Division – have created a revolutionary new type of telescope mirror. These mirrors will be deployed as part of a CubeSat, one which may represent a new breed of low-cost, highly effective space-based telescopes. This latest innovation also takes advantage of another field that has seen a lot of development of late. CubeSats, like other small satellites, have been playing an increasingly important role in recent years. Unlike the larger, bulkier satellites of yesteryear, miniature satellites are...

How much can you pack on top of one rocket? A United Launch Alliance Atlas V is carrying up the U.S. Air Force's so-called secret space plane, The Planetary Society's solar sail, and several CubeSats, or tiny satellites. The launch window is Wednesday from 10:45 a.m. ET and 2:45 p.m. ET at Cape Canaveral Air Force Station in Florida. You can watch it on a webcast starting at 10:45 a.m. ET. The Air Force space plane is actually called the X-37B Orbital Test Vehicle. This is the fourth mission for the plane. It looks like a small space shuttle, but...

Explanation: Cubes are orbiting the Earth. Measuring ten-centimeters on a side, CubeSats -- each roughly the size of a large coffee mug -- are designed to be inexpensive both to build and to launch. Pictured above, three CubeSats were released from the International Space Station (ISS) last November by the arm of the Japanese Kibo Laboratory module. CubeSats are frequently created by students as part of university science or engineering projects and include missions such as collecting wide angle imagery of the Earth, testing orbital radio communications, monitoring the Earth's magnetic field, and exploring the Earth's surrounding radiations. Depending on...
