While the first part of Europe's and Russia's ExoMars mission took off on time in March, the second phase has been delayed. They've decided to launch their Martian rover, which will be capable of drilling up to two meters (6.5 feet) below the surface, in 2020 instead of 2018 like they previously planned. According to the BBC, Roscosmos' engineers have been having a hard time designing rover's landing mechanism. At the same time, European Space Agency's engineers are also having trouble putting together all the components and instruments ExoMars' second phase needs.
