The DART spacecraft, which resembles a golf cart, was traveling at high speed when it struck the asteroid Dimorphos. The 600 kg DART spacecraft was only able to mildly accelerate the 163 m diameter asteroid Dimorphos in its orbit; it was not able to destroy or knock it away. This is still a success because an asteroid only needs to divert slightly while it is still there if it is intended to strike Earth-like Chicxulub, the asteroid that wiped out the dinosaurs 66 million years ago. Before the impact, planetary scientist Nancy Chabot, DART coordinator at JHUAPL, remarked, "The spacecraft is quite little." "We sometimes compare it to driving a golf cart into the huge pyramid," says the speaker. The exact precision of the hit prevented NASA from needing to account for up to 21 eventualities and assisted in impact estimation.

NASA experts have created up to 21 backup plans if the DART train "derails" during a suicide mission. The DART spacecraft, which resembles a golf cart or is used on a golf course, struck the asteroid Dimorphos at 19:14 on September 26 EDT, according to NASA (Eastern US time while flying at high speed). The 600 kg DART spacecraft will only be able to mildly accelerate the 163 m diameter asteroid Dimorphos in its orbit; it will not be able to destroy or knock it away.

"We sometimes compare it to driving a golf cart into the huge pyramid," says the speaker.

If this had been an actual threat and not just a test, then upon completion DART would have provided enough information about how an incoming object's trajectory could be altered. This would give us enough time for either an evacuation or for developing a more sophisticated interceptor system.
