One step closer to a CubeSat swarm mission

RACE double CubeSat mission

The next revolution in space technology could be using swarms of small spacecraft working together rather than one much bigger spacecraft. Following an open call for ideas, ESA selected seven projects for mission/system concept study. On 26 April the teams showcased their work in ESA's Concurrent Design facility. Two studies were selected for further development.

NASA’s Voyager 1 Resumes Sending Engineering Updates to Earth – Voyager https://blogs.nasa.gov/voyager/2024/04/22/nasas-voyager-1-resumes-sending-engineering-updates-to-earth/

For the first time since November, NASA’s Voyager 1 spacecraft is returning usable data about the health and status of its onboard engineering systems. The next step is to enable the spacecraft to begin returning science data again. The probe and its twin, Voyager 2, are the only spacecraft to ever fly in interstellar space (the space between stars).

This is beyond awesome! This is a marvel of #engineering and #science

Simulating tumbling reaction wheel reentry

image

Video: 00:02:04

A reaction wheel – one of the heaviest parts of a space mission, its changing rotation used to shift a satellite’s orientation – seen in a plasma wind tunnel belonging to the High Enthalpy Flow Diagnostics Group (HEFDiG) at the University of Stuttgart Institute of Space Systems (IRS). Arc-heated gas in the test chamber reaches speeds of several kilometres per second, reproducing reentry conditions, while the reaction wheel itself is being rotated, reproducing the tumbling that takes place as a satellite plunges through the atmosphere.

The reaction wheel itself comes from Collins Aerospace in Germany, which has supported Design for Demise (D4D) activities for many years and introduced several modifications to their TELDIX reaction wheel making it more likely to come apart during satellite reentry in support of demisability.

This test clip was presented during this year’s Space Mechanisms Workshop at ESA’s ESTEC technical centre in the Netherlands, focused on current and future requirements and guidelines to reduce the risk from orbital debris, including ESA’s Zero Debris Charter. The event was attended by more than 130 space mechanisms specialists from European industry and academia.
