After early struggles, NASA’s formidable mission to Titan is “on track” for launch

So how is Dragonfly doing now?

In latest years the Dragonfly mission has began to obtain the funding and assets promised when NASA chosen the mission six years in the past. So how is it doing?

“The Dragonfly team is killing it,” stated Bobby Braun, who’s head of APL’s Space Exploration Sector, in an interview. “Probably the best part of my day is watching that team hit their milestones.”

Both the spacecraft’s {hardware} and software program are progressing properly, he stated. Braun expressed confidence that the spacecraft is “on track” for a July 2028 launch date on a Falcon Heavy rocket. NASA confirmed this in a new update this week. On this timeline the spacecraft would arrive at Saturn’s largest moon, Titan, in 2034.

This is a difficult mission for a lot of causes, starting with getting all the way down to the floor. Because Titan has a thick environment, it should take about 90 minutes for the spacecraft to descend. “Curiosity had 7 minutes of terror when it landed on Mars,” Braun stated. “We’re going to have 90 minutes of terror on Titan.”

Unlike Mars, the place there have been a number of orbiters to gather high-resolution floor knowledge about potential touchdown websites, NASA solely has imagery from the Cassini spacecraft that explored the Saturnian system from 2004 to 2017. Fortunately, this spacecraft deployed a small European probe, Huygens, that landed on Titan in 2005 and survived for about an hour. Dragonfly will draw on the experiences and atmospheric knowledge collected by Huygens.

Among the important thing applied sciences on Dragonfly is a sophisticated Terrain Relative Navigation system to survey the floor and determine hazards. This can be helpful not simply in the course of the preliminary touchdown however for subsequent flights because the rotocraft makes 20-minute jaunts throughout the floor, touring a couple of kilometers at a time. Between every autonomous flight, the spacecraft will recharge its batteries utilizing a radioisotope thermoelectric generator, or RTG energy system. Dragonfly will want this energy to transmit knowledge immediately from the floor of Titan again to Earth, as there can be no relay spacecraft in orbit across the moon.
