During the years 2005-2010 the double-Penning-trap mass spectrometer JYFLTRAP has been used to measure the masses of 90 ground and 8 isomeric states of neutron-deficient nuclides with a typical precision of better than 10 keV. The masses of 14 nuclides - ⁸⁴Zr, ^{88, 89}Tc, ^90-92Ru, ^92-94Rh, ^{94, 95}Pd, ^{106, 108, 110}Sb - have been experimentally determined for the first time. This article gives an overview on these measurements and their impact on the modeling of the astrophysical rp-process.
