A spacecraft that may present the propulsion essential to achieve different planets whereas additionally being reproducible, comparatively mild, and cheap could be an incredible boon to bigger missions within the interior photo voltaic system. Micocosm, Inc., primarily based in Hawthorne, California, proposed simply such a system through a NASA Small Enterprise Innovation Analysis (SBIR) grant. Its Hummingbird spacecraft would have offered a platform to go to close by planets and asteroids and a payload to do some fundamental scouting of them.
Massive house missions are costly, so utilizing a a lot cheaper spacecraft to gather preliminary knowledge on the mission goal may doubtlessly assist lower your expenses on the bigger mission’s remaining design. That’s the position that Hummingbird would play. It’s designed primarily as a propulsion system, with slots for radiation-hardened CubeSat parts in addition to a bigger exchangeable payload, reminiscent of a telescope.
The important thing element of the Hummingbird is its propulsion system. It makes use of a rocket engine that runs on hydrazine gas. Extra importantly, it holds quite a lot of that gas. A completely assembled system is predicted to weigh 25 kg “Dry”—which means with out propellant put in—whereas a completely fueled “Moist” system would weigh an estimated 80 kg.
That may give Hummingbird loads of “oomph” – sufficient to deliver its orbital pace as much as an estimated 3.5 km/s delta-V, which is required for attending to hard-to-reach objects like some near-Earth asteroids. Nevertheless, it may additionally attain different, bigger locations, like Mars and even Venus, the varied Lagrange factors, and even Mars’ moons.
When it bought there, the prototype of Hummingbird described in a paper introduced again in 2013 would take photographs of its goal world utilizing an Exelis telescope. The producer of this telescope has since been purchased by Harris Methods, which was then rolled into L3Harris Applied sciences, the proprietor of Aerojet Rocketdyne. Nevertheless, the authors stress that the payload itself was interchangeable and might be tailor-made to the mission that it was meant to scout.
The Hummingbird bus was additionally the gas tank, and it had extra slots for CubeSat parts. These parts might be used for additional knowledge assortment or knowledge evaluation. Nevertheless, the paper doesn’t essentially point out how Hummingbird would deal with commonplace CubeSat operations, like perspective management or communications again to a floor station.

These may doubtless have been labored out in future iterations. Moreover, the ultimate design was printed earlier than the dramatically lowered value of attending to orbit, which is now obtainable – the authors don’t even point out a “Falcon” as a possible launch service. Rather a lot has modified within the house trade within the final 11 years. Nonetheless, the thought behind Hummingbird, an affordable, adaptable platform for preliminary scouting missions to attention-grabbing locations within the interior photo voltaic system, has but to see its day within the Solar – the venture didn’t seem to obtain a Part II SBIR grant, which may have continued its growth. However perhaps, sometime, it or an identical system will see the sunshine of interplanetary house.
