That's why Nasa is launching its TRACERS mission in April which will look at how activity from the Sun, such as solar wind, interacts with Earth's magnetic field. However, the US Space Agency discovered a number of issues with the Starliner spacecraft they were due to travel on, including several helium leaks in its capsule. From the challenges of providing optimal nutrition to managing the risks posed by microgravity, NASA works to predict, assess, and solve the problems that humans encounter in space. It is possible to detect oxygen and other gases on other planets by studying the light reflected from planets. If we found evidence of oxygen in the atmosphere of another planet, it could indicate the presence of life forms. So scientists are using different methods to see if there is life on planets other than the Earth.
Sputnik 2 followed, carrying the first living being in space, a dog named Laika. The "Blue Marble" photograph of Earth from space transformed humanity’s perspective of our planet. Human settlement on Mars represents one of the most ambitious goals of modern space exploration. The International Space Station represents humanity’s largest collaborative space project.

Modern satellites provide essential services from communications to Earth observation and scientific research.
These satellites quickly found numerous civilian uses in such areas as personal navigation, surveying and cartography, geology, air-traffic control, and the operation of information-transfer networks. They illustrate a reality that has remained constant for a half century—as space capabilities are developed, they often can be used for both military and civilian purposes. Spaceflight is used in space exploration, and also in commercial activities like space tourism and satellite telecommunications. Additional non-commercial uses of spaceflight include space observatories, reconnaissance satellites and other Earth observation satellites.
That mysterious 'Wow! signal' from space? Scientists may finally know where it came from — and it's probably not aliens
India and China sent the Chandrayaan-1 (2008) and two Chang’e (2007, 2010) missions, respectively, to orbit the Moon. China’s Chang’e 3 mission landed a small rover, Yutu, on the Moon in 2013, and Chang’e 4 made the first landing on the far side of the Moon in 2019. China placed the Tianwen-1 lander and the Zhurong rover on Mars in 2021, and that same year Hope, an orbiter from the United Arab Emirates, entered Mars orbit. NASA’s Dawn mission (2007) orbited the large asteroid Vesta from 2011 to 2012 and entered orbit around the dwarf planet Ceres in 2015. In the years after World War II, governments assumed a leading role in the support of research that increased fundamental knowledge about nature, a role that earlier had been played by universities, private foundations, and other nongovernmental supporters.

The International Space Station (ISS) is currently the largest and oldest of the 2 current fully functional space stations, inhabited continuously since the year 2000. The other, Tiangong space station built by China, is now fully crewed and operational. The main objective of space exploration is to study and research the planet Earth, the solar system and the cosmos and develop technological advancements for societal improvements. Space exploration has advanced human knowledge, technology, and culture in many ways. It has inspired generations of scientists, engineers, artists, and dreamers to pursue their passions and curiosity. It aids the human desire of exploring the unknown and expands the horizons of humanity.

Their claim was not universally accepted, but it led to an accelerated program of Martian exploration focused on the search for evidence of the action of liquid water, thought necessary for life to have evolved. Europe launched the Mars Express mission in 2003 and the ExoMars Trace Gas Orbiter in 2016. A major long-term goal of the Mars exploration program is to return samples of the Martian surface to Earth for laboratory analysis, and Perseverance collected samples in 2021 for a future sample return mission. States and space agencies have been engaging in space exploration since the first space launch. The first space launch led to the first human space flight, which led to the first moonwalk. Nowadays focus has shifted to joint human and robotic missions, near-Earth asteroids, Mars and destinations beyond our own solar system.
Given its axial tilt of 97.77°, with its polar regions exposed to sunlight or darkness for long periods, scientists were not sure what to expect at Uranus. Voyager 2 also examined its ring system and the moons of Uranus including all five of the previously known moons, while discovering an additional ten previously unknown moons. Saturn has at least 62 known moons, although the exact number is debatable since Saturn's rings are made up of vast numbers of independently orbiting objects of varying sizes. The largest of the moons is Titan,

Titan holds the distinction of being the only object in the Outer Solar System that has been explored with a lander, the Huygens probe deployed by the Cassini spacecraft.
