More than 50 years of space exploration has not only satisfied human curiosity and built up international cooperation, but also improved life on Earth. Space exploration is an open-ended process which started 50 years ago. It enables access to unknown terrains with robots and humans, thereby opening new frontiers. Progress of goal deep space exploration was reviewed. China's current deep space missions are also briefly introduced. Focused on the vision and voyages for China's deep space exploration in 5 or 10 years. Like the Chinese Lunar Exploration Program (CLEP), we embark on a journey to Mars. We will spend few decades on Mars with the robotic explorers. Unlike CLEP, scientists proposed to build Moon research station by 2030.

Great progress has been made in the research of solar corona and interplanetary physics by the Chinese scientists during the past two years (2014-2016). Nearly 100 papers were published in this area. In this report, we will give a brief review to these progresses. The investigations include:solar corona, solar wind and turbulence, superhalo electron and energetic particle in the inner heliosphere, solar flares and radio bursts, Coronal Mass Ejections (CMEs) and their interplanetary counterparts, Magnetohydrodynamic (MHD) numerical modeling, CME/shock arrival time prediction, magnetic reconnection, solar variability and its impact on climate. These achievements help us to better understand the evolution of solar activities, solar eruptions, their propagations in the heliosphere, and potential geoeffectiveness. They were achieved by the Chinese solar and space scientists independently or via international collaborations.

The support given by Earth observation data and Earth system science play an increasingly important role in global change, regional sustainable development, extreme events, and the development of social and economic needs. This field is also moving towards systematization, platforms, and standardized development. In December 2015, nearly 200 parties of the United Nations Framework Convention on Climate Change agreed in Paris to make arrangements for global action in response to climate change by 2020. China jointly issued a climate change adaptation strategy for cities in 2016 and then elevated national action to respond to climate change. China's Earth Observation and Earth Science development is facing new challenges as it supports the national civil space infrastructure and high-resolution Earth observation system.
