A recent study presented this week at the 2023 meeting of the American Geophysical Union discusses observations of “hot Jupiters” from the NASA-funded CubeSat mission known as the Colorado Ultraviolet Transit Experiment (CUTE). Unlike most exoplanet-hunting telescopes, whose sizes are comparable to a small school bus, CUTE measures 36 centimeters (14 inches) in length, equivalent to the size of a cereal box. These findings come after members of the team, which consists of undergraduate and graduate students, published an overview paper about CUTE in The Astronomical Journal in January 2023 and results from CUTE observing WASP-189b in The Astrophysical Journal Letters in August 2023.

ESA’s Hera Mission is Bringing Two Cubesats Along. They’ll Be Landing on Dimorphos

In about one year from now, the European Space Agency will launch its Hera mission. Its destination is the asteroid Didymos, and it’ll be the second human spacecraft to visit the 390-meter chunk of rock. NASA’s DART mission crashed a kinetic impactor into Didymos’ tiny moonlet Dimorphos as a test of planetary defence.

Hera will perform a follow-up investigation of the binary asteroid to measure the size and morphology of the impact crater on Dimorphos. To help it along, it’s taking two tiny CubeSats that will land on Dimorphos.

A Flock of CubeSats Will Use Wings to Maneuver at the Edge of Space

CubeSats are taking on more and more responsibility for remote monitoring of the Earth. As they become more ubiquitous, they will also gain more varied propulsion systems. Or, in the case of a new set of monitoring CubeSats from INTA, Spain’s Institue of Aerospace Technology, no propulsion system at all.

Spacecraft Could be Equipped With Tiny Thrusters That Use Water for Propellant

Engineers working with the European Space Agency have developed a new thruster design smaller than the tip of your finger. Despite its small size, this mini-thruster designed for CubeSats appears to be highly efficient without the use of toxic chemicals.

A Year After a Failed Launch, Firefly Reaches Orbit and Deploys Satellites

Alpha FLTA002 mission successfully reached orbit but not so successfully deployed customer payloads. It lifted off on October 1, 2022 at 12:01am PST from Vandenberg Space Force Base in California. Credit: Firefly Aerospace.

Edited on 10/6/22 to add new information from Seradata.

Commercial space company Firefly Aerospace successfully launched its Alpha rocket for the first time last weekend, reaching orbit and deploying three satellites. While the latest determination of the satellites’ orbit reveals they may have not been placed in the correct orbit, the company appears to consider the orbit high enough to be considered a success. But others might not agree.

This launch comes just over a year after the Alpha rocket’s first launch attempt exploded two and a half minutes after liftoff from Vandenberg Space Force Base in California.

A Mission to Reach the Solar Gravitational Lens in 30 Years

NASA’s Institute for Advanced Concepts is famous for supporting outlandish ideas in the astronomy and space exploration fields. Since being re-established in 2011, the institute has supported a wide variety of projects as part of its three-phase program. However, so far, only three projects have gone on to receive Phase III funding. And one of those just released a white paper describing a mission to get a telescope that could effectively see biosignatures on nearby exoplanets by utilizing the gravitational lens of our own Sun.

Finally, a Practical use for Space-Based Power Beaming. Sending Power to Satellites in Shade

Power beaming is one of those technologies that can completely change the world.  Almost unlimited power wherever it is needed, whenever it’s needed, is literally a technology straight out of science fiction.  Researchers have been working on the technology for decades at this point, but there has been little commercial headway so far, so what is holding this revolutionary technology up?  A “killer app” would certainly help move it along – and that is what a team from Space Power, a private company, and the University of Surrey think they have found in the form of powering other microsatellites.

Company Tests Iodine Thruster in Space for the First Time

Ion thrusters have played second fiddle to chemical rockets for most of the history of space exploration.  Part of that is because of their inability to launch payloads into orbit.  But in space, their high thrust-to-weight ratio has plenty of appeal.  Other features have held the technology back, including the difficulty of working with the thruster’s fuel source – xenon.  Now, a team of engineers and scientists from ThrustMe, a French start-up that focuses on developing advanced propulsions systems, have developed an ion thruster that works on an entirely new and much easier to use material – iodine.

Artemis 1 is Launching in February

It’s been a long time coming, but NASA’s next moon rocket is just months from liftoff on its first uncrewed test flight. The Space Launch System (SLS) is a super heavy-lift vehicle capable of delivering 95 tons to Low Earth Orbit, but its primary purpose will be to deliver humans to lunar orbit and, eventually, to the lunar surface. SLS has been in development since 2011, and it’s faced a series of delays, but launch day is finally within sight. Earlier this month, the rocket was fully stacked for the first time in the Vehicle Assembly Building at the Kennedy Space Center, and the Orion capsule (the spacecraft’s crew cabin) was attached to the top. The full stack stands an impressive 322 feet tall, just shy of the Saturn V’s 363 feet.
