China's Mars Mission Leaves US Behind

Hong Kong CNN — China’s historic attempt to bring samples from Mars to Earth could launch as soon as 2028, two years earlier than previously stated, according to a senior mission official.

The country’s Tianwen-3 mission would carry out two launches “around 2028” to retrieve the Martian samples, chief mission designer Liu Jizhong said at a deep-space exploration event in eastern China’s Anhui province last week.

The projected mission launch is more ambitious than a 2030 target announced by space officials earlier this year, though the timeline has fluctuated in recent years. A 2028 target appears to return to a launch plan described in 2022 by a senior scientist involved with the Tianwen program – a mission profile that would see samples returned to Earth by 2031.    READ MORE...

Time for Nuclear

America’s Urgent Need to Develop Space Nuclear Propulsion Systems
As NASA finally launches the first Space Launch System (SLS) mission, America is failing to invest in critical space propulsion technology needed to send astronauts to Mars.

The United States must develop space nuclear propulsion technologies to enable 21st-century human missions to Mars. Congress should immediately direct NASA and the Department of Energy to partner with a University Affiliated Research Center or Federally Funded Research and Development Center to create a new National Space Nuclear Propulsion Laboratory.

It is naive and against national interests for the U.S. to rely on expensive, outdated, slow, single-use chemically propelled rockets like SLS to transport astronauts to Mars. Instead, America must aggressively invest in developing space nuclear propulsion systems.

Nuclear technology, including nuclear electric propulsion (or “NEP”) and nuclear thermal propulsion (or “NTP”), will be a space travel game-changer with profound implications for deep space mission speed, agility and capability.

The increased propulsive power of nuclear systems will allow humans to head to Mars on a more regular cadence than the current mission launch windows of “every 26 months.” Nuclear propulsion also will allow power for astronauts on Mars missions to abort and return to Earth in the event of an emergency.  READ MORE...
