NASA SmallSats Use Powered Earth Flybys for Unconventional Trajectory
Two NASA smallsats, ESCAPADE, have completed powered Earth flybys, using the Oberth effect to propel themselves toward Mars. The spacecraft, built by Rocket Lab, will study space weather at Mars, examining the interaction between the solar wind and the planet’s magnetosphere and atmosphere. The mission is the last surviving part of NASA’s SIMPLEx program, which aimed to support low-cost planetary science missions. The ESCAPADE spacecraft are expected to arrive at Mars in September 2027, according to SpaceNews.
