Lift‐off : The low vapor toxicity of ionic liquids (ILs) make them attractive replacements for hydrazine in rocket fuel. However, ILs will fail to fulfill their revolutionary promise unless toxic oxidizers such as HNO 3 or N 2 O 4 can be replaced with safer alternatives such as H 2 O 2 . The ILs presented here are hypergolic with H 2 O 2 (see picture) and are hydrogen‐rich, thus helping to boost performance.
