Cubesat. they cost of a fraction of traditional satellite so we can launch many more satellites into space, collecting a lot more data that allows us to track global warming and interplanetary life more accurately. these networks could also bring wider spread, faster internet coverage across the world. some cubesats now use superfast communication lasers to interact with each other. these liquid filled lenses can bend light by 90 degrees so the information sent can travel more directly between cubesats. of course, lasers need power to operate, which is why this we build another solution. this project is called flat, the folded, lightweight actuated position system. this bends when heated so we can angle our satellite solar panels to collect maximum energy from the sun. ....

ESA - The Incredible Adventures of the Hera mission – Presenting Hera

The Incredible Adventures of the Hera mission – Presenting Hera
Meet Hera, our very own asteroid detective. Together with two briefcase-sized Cubesats – Milani the rock decoder and Juventas the radar visionary – Hera is off on an adventure to explore Didymos and Dimorphos, an asteroid pair typical of the thousands that pose an impact risk to planet Earth.
The Incredible Adventures of the Hera mission – Presenting Hera
Planetary defence requires planetary cooperation. Hera is set to rendezvous with the asteroid pair in 2026, by which time NASA’s DART spacecraft will have already impacted Dimorphos, the smaller of the two asteroids. This cosmic shove is expected to slightly shift Dimorphos’ orbit around Didymos. ....

"A wideband metal-only patch antenna for cubesat" by Suhila Abulgasem, Faisel Tubbal et al.

This article presents a compact wideband high gain patch antenna for CubeSat. The proposed metal-only antenna mainly consists of an upper patch, a folded ramp-shaped patch and shoring pins connecting the antenna with the ground plane. By adjusting the lengths and widths of two arms of the upper F-shaped patch, a second resonant frequency is generated, and hence, the −10 dB bandwidth is increased. Moreover, the effect of arms’ lengths and widths on reflection coefficients, operating frequency and bandwidth is presented. To validate the design and the simulation results, a prototype metal-only patch antenna was fabricated and tested in a Chamber. A good agreement between the simulated and measured results is achieved. The measured results show that the fabricated prototype achieves a −10 dB bandwidth of 44.9% (1.6–2.7 GHz), a small reflection coefficient of −24.4 dB and a high efficiency, i.e., 85% at 2.45 GHz. The radiation performance of the proposed antenna is measured, show ....

There probably isn’t a more complex process out there than putting together a spacecraft. No matter the task envisioned for it by Earth-based engineers, a spacecraft is one of the most complex pieces of machinery in exitence. And like most other machinery, they need to be tested very thoroughly.

The American space agency has one of the most rigorous such programs in existence. Take the Orion capsule that will head for the Moon with humans on board in a few years’ time. Not only is it subjected to hard testing on the ground, but it will also be sent empty to the Moon before actually carrying people there. ....

TWIRL 2: SpaceX's Starship SN10 could take flight

Things are a little quieter this week on the space launch front compared with last week. This week we can expect to see Rocket Lab’s Electron rocket launch a Blacksky Global satellite among others, Iran’s Pars 1 satellite is set to make another launch attempt, and SpaceX is expected to launch the successor to Starship SN9 which exploded several weeks ago.
The first launch of the week is due on Monday from New Zealand where Rocket Lab will launch an Electron rocket carrying Blacksky Global satellite and several CubeSats dubbed Centauri 3, Gunsmoke-J, M2 (A/B), Myriota 7, and Veery Hatchling. The firm has decided to call the mission “They Go Up So Fast” - something which is actually true thanks to the rocket weighing just 12,500 kg. On the day of launch, Rocket Lab will publish a live stream on its website. ....
