All of the guards were quite surprised at what had been found, most especially Afterglow "By Celestia, I knew all along we weren't alone!" he'd say excitedly before taking upon his more professional character. As the guards circled above the object, Afterglow began to formulate a plan and did some hoof signals to the other carriages. The other carriages flew closer so they could all converse easily. Afterglow was going to converse with them about the plan as to how to deal with this strange occurrence
"First things first, we must secure the area. You 4, when we land make sure to secure the area. Nopony gets in or out of this area unless I say so. Is that clear?" he'd ask those 4 guards of one of the carriages that, and they would nod. "Next, we need to wear our masks and scan the area for radiation or any unwanted fumes. This...object might be toxic or dangerous and we want to take all precautions we can just in case of anything dangerous." they would all agree with that statement.
"Preston Star, Stern Steel, Fly Heart! You will be with me. Be on your guard, stay alert and aware at all times. This could be anything, friendly, foe or otherwise. If this proves to contain hostile beings we will not hesitate to use force. If not, we will try to communicate. But first things first, secure the perimeter, and we will examine the safety of this situation. If all is fine, we will attempt to look for entry into this object. If there are non-hostile beings that are injured, we will attempt to heal them if they are injured." Afterglow spoke, and after a brief conversation the guard carriages stepped down. With a bit of hesitation, the guards agreed.
The 3 carriages touched down a close distance away from the object on the opposite side from where the CMC were, so they wouldn't catch view of them yet. Afterglow, Preston Star, and Fly Heart among the two solar guard ponies got their full hazmat suits on as well as breathing masks on. The other guards did so just to be safe upon Afterglow's orders. After they were all suited up, they would put their armour on.
Afterglow and his group of guards would begin to inspect the object and scanning it with the various devices they had on hand to assess the safety, while the remaining guards moved away from the object and began to set up whatever equipment they needed and began to guard over the area and made sure nothing, or nobody would get access to the area without being noticed.

Sweetie looked to her two friends cautiously but also excitedly. "It looks like those guards have landed, we should be small enough to avoid being spotted over the distances around this strange object. Its obviously not a meteor! We could get alien cutie marks! Wouldn't that be something? I say we go for it and check it out!" she would agree and made sure no guards were within close distances of where the CMC were.
Sweetie Belle had noticed that none of the guards were likely going to spot them. At least, not yet. She would run up to the object, eyes wide in amazement upon this being an alien craft.
