Artemis I will be the first integrated flight test of an uncrewed Orion spacecraft atop the Space Launch System (SLS) rocket. This stage of the mission
will test Orion's ability to operate beyond low Earth orbit; it will also test deep space navigation and communication systems. SLS will send Orion to a
stable orbit beyond the Moon. From that orbit, Orion will return to Earth and demonstrate its ability to reenter and land. (Image: NASA)
Though it's the largest request in many years, it barely keeps
pace with inflation and is nowhere near on par with other science-focused
federal agencies.
While the Cold War Space Race pitted the United States
against the Soviet Union, today China is America's top rival. As
the U.S. space budget has remained relatively flat considering
inflation, Beijing has dramatically increased its capabilities and
investments in aerospace.
At $8 billion, China's space budget is now second only to the
United States. But those dollars go further in China, since the
government has greater purchasing power in a low-wage economy
and less stringent government oversight for public safety
and pollution. In 2020, it completed its Beidou satellite network,
a potential competitor to the U.S. GPS system. Last year,
it launched its Tiangong space station and landed a robotic
rover on Mars.
The implications of China's emergence as a space superpower
are practical as well as symbolic. Space and defense technology
overlap substantially, so advances in one signal advances in
the other.
