We finally have the technological means to discover interstellar items. Weve discovered 2 in the last couple of years, Oumuamua and 2I/Borisov, and there are undoubtedly more out there. As such, theres been a great deal of interest in establishing a mission that might check out one once we find it. But what would such a mission look like? Now, a draft paper from a team of mainly American scientists has actually taken a stab at responding to that concern and moved us one step more detailed to releasing such an objective.
Part of what makes an interstellar visitor objective fascinating is that interstellar visitors are so weird. Borisov imitated a common comet once it got in the planetary system, however Oumuamua was a different monster totally.
It never established a cometary tail, as many researchers expected it to. It likewise exhibited velocity that didnt seem to be accounted for by radiative or other ways, leading some prominent researchers to claim it may have even been an alien probe.

Once found, getting to the ISO is the next job. In essence, when were able to find ISOs, it is simply a matter of patiently waiting for the right opportunity.
Once the ISI reaches the ISO, it can then begin close-quarters observation, consisting of a full spectroscopic map of both natural and artificial products, which might help settle the dispute about whether such items are alien-made probes. It could also keep track of for any outgassing that might discuss the strange forces acting on Oumuamua..
There are certainly plenty more exciting things that researchers would like to understand about the first interstellar things we visit. From the calculations in this paper, there will be plenty of opportunities to do so and plenty of information to gather when we do. Time to get on to the planning phases, then!

It has more than one benefit– first, theres extremely little fuel required to remain on station, and any ISI may require to remain waiting in storage mode for many years. Once it is called into action, it needs to react quickly, and another citizen of L2 could assist it do so.
NASAs Time-domain Spectroscopic Observatory (TSO) is a 1.5-m telescope prepared to find at the L2 Lagrange point, along with more well-known telescopes like the JWST. It can take 2-5 days to focus on a specific item, making it ineffective when tracking ISOs.
It might be supplemented by another telescope, the planned Near Earth Object Surveyor, which is intended to reside at the L1 Lagrange point of the Earth-Moon system. When combined with the TSO, these 2 quick-reacting telescopes need to be able to catch images of any ISO that gets in the inner solar system that isnt directly on a trajectory along the L1-L2 baseline.
And to do that, we have to have an objective that can catch it. The Vera C Rubin Observatory Legacy Survey of Space and Time (LSST) will be able to find somewhere between 1-10 interstellar items about the exact same size as Oumuamua every year, according to the authors estimations.

The finest method to combat such fanciful claims is to closely examine them. And to do that, we need to have an objective that can capture it. But initially, we would need to see it, and astronomers are currently dealing with that.
The Vera C Rubin Observatory Legacy Survey of Space and Time (LSST) will have the ability to spot somewhere between 1-10 interstellar things about the very same size as Oumuamua every year, according to the authors estimations. Thats lots of opportunity to find the ideal prospect. However what requirements should that candidate satisfy?
Most notably would be “where is it originating from?” While there isnt a “best” angle for an interstellar object (ISO) to approach from, it does make a difference based upon where we store the “interstellar interceptor” (ISI). According to the paper, the very best location for that is most likely the Earth-Sun L2 Lagrange point..
