NASA’s newest exploration spacecraft launched over the weekend, starting a 12-year journey to go to Jupiter’s Trojan asteroids.
A instrument acquainted to Wall Avenue was used to craft the mission’s intricate path: Microsoft Excel.
The Lucy spacecraft, which Lockheed Martin constructed and United Launch Alliance’s Atlas V rocket launched for NASA on Saturday, is predicted to journey 4 billion miles via house to fly by and examine eight asteroids.
Years earlier than Lucy took off, Lockheed Martin mission architect Brian Sutter used Excel to chart the mission’s path and select which of the about 5,000 Trojan asteroids the spacecraft ought to go to.
“A part of the science of this mission was to attempt to have a look at as many of those Trojans as we will in a single mission,” Sutter instructed CNBC.
Whereas Lockheed Martin has a “excessive constancy” instrument to run particular person trajectories, Sutter stated that will have taken “without end.” He as an alternative turned to an Excel macro, which is “completely fitted to sorting via massive portions of knowledge.”
“I had already discovered a trajectory that linked two of the asteroids to a trajectory that additionally linked to Earth,” Sutter stated.
Orbit propagation – or modeling the long run location of objects in house – “is what I do,” Sutter defined. Whereas his macro consists of “totally different equations than you’d usually put into Excel,” he emphasised that “on the finish of the day it is all math.”

Sutter took a broad record of 750,000 asteroids and entered them into Excel to “see in the event that they ever unintentionally type of come shut to one another.”
“I believe this factor took about 12 hours to cycle via all 750,000 of them,” Sutter stated. After he ran the macro, he had “a bit of record of 10 to twenty asteroids that the spacecraft was going to be flying near.”
His use of Excel to assist chart Lucy’s trajectory turned well-known inside Lockheed Martin. He recalled {that a} colleague as soon as described to others that Sutter “constructed essentially the most ridiculously difficult Excel spreadsheet I’ve ever seen in my life.”

The Lucy mission, which has a complete price of $981 million, is predicted to go to its first asteroid in 2024. Additional flybys are set to happen till 2033.
Whereas the launch was profitable and the spacecraft is secure, NASA stated on Sunday that one of many spacecraft’s two photo voltaic arrays “is probably not totally latched.”
“Lucy can proceed to function with no risk to its well being and security,” NASA stated. “The group is analyzing spacecraft knowledge to grasp the scenario and decide subsequent steps to realize full deployment of the photo voltaic array.”
