It’s a technology looking for a new mission.

The technology is solar electric propulsion (SEP), which NASA has identified in recent years as a key enabler for eventual human missions to Mars. SEP, the agency argued, could be used to propel cargo missions to Mars in advance of crewed missions much more efficiently than conventional chemical propulsion systems.

High-power SEP was to be tested in interplanetary space on the Asteroid Redirect Mission (ARM), powering the robotic spacecraft that would travel to a near Earth asteroid, grab a boulder off its surface, and fly back to cislunar space. However, NASA announced earlier this year it planned to cancel ARM, and Congress, never much of a fan of the mission, has shown no signs of opposing it.

The US military’s nuclear arsenal is controlled by computers built in the 1970s that still use 8in floppy disks.

A report into the state of the US government, released by congressional investigators, has revealed that the country is spending around $60bn (£40.8bn) to maintain museum-ready computers, which many do not even know how to operate any more, as their creators retire.

The Defense Department’s Strategic Automated Command and Control System (DDSACCS), which is used to send and receive emergency action messages to US nuclear forces, runs on a 1970s IBM computing platform. It still uses 8in floppy disks to store data.

Government finance will lead the way in AI research, including the development of supercomputers, and high performance semiconductor chips, software and the hiring of key talent to lead the field, China’s science and technology minister Wan Gang said in March during the country’s parliamentary meeting.

The Chinese government’s July 8 plan aims to keep pace with AI technology by 2020, make major breakthroughs by 2025, and lead the world in AI by 2030.

Dear Mum,

We’ve missed you over the ten long years since you passed away. You wanted me to write to you to tell you what’s happened, so now in 2030 I am fulfilling that wish.

Congress took the first step toward setting rules for self-driving cars, as a House panel unanimously approved a measure that would allow thousands of automated vehicles to hit the road while federal regulators develop safety standards and preempt state rules.

The legislation garnered bipartisan support after Republican leaders adopted Democratic proposals for provisions to bolster safety oversight of self-driving vehicles by federal regulators.

SAN JOSE, Calif. – The U.S. Department of Defense is working with partners on multiple technologies that would make any foundry a trusted source to make classified ASICs for the military. If the government is successful it will be able to tap leading-edge process technologies from multiple fabs by 2019.

The U.S. government currently works with a single fab now operated by Globalfoundries and limited to 32nm and higher design rules. The partnership is a continuation of a longstanding “trusted foundry” deal with IBM, which sold its fabs to GF in 2015.

“We have a very good partner in Globalfoundries, and many people are still there from the [former] IBM…[that help] manage that government ASIC business, and that still works quite well for 32nm and up,” said Bill Chappell, a director at the Defense Advanced Research Projects Agency that oversees the trusted foundry programs.

Greenland’s ice sheet, the planet’s second largest after Antarctica, is melting at an alarming rate, losing an estimated 90 cubic miles of ice a year. The melt water that ends up in the ocean is raising sea levels. And then there are the countless glaciers in the Alps, Andes, Himalayas, Rockies and Tibetan Plateau, all melting as our unceasing carbon dioxide emissions — a staggering 35 to 40 billion tons a year — trap more and more heat.

As the Trump administration dismantles the federal government’s efforts to respond to global warming, the natural world has come calling with a reminder: An iceberg the size of Delaware broke off Antarctica’s Larsen C ice shelf in recent days, yet another indication of the rapid change now occurring on the world’s iciest continent.

This is the third floating ice shelf in recent years in Antarctica’s Weddell Sea to fully or partly break up, the first two subverted by warming ocean waters and air temperatures. The Larsen A broke up in 1995. Seven years later, after months of unusually warm temperatures, the Rhode Island-size Larsen B shelf became riddled with meltwater ponds, then fell apart virtually overnight, shattering into millions of pieces. Now a 120-mile-long chunk of the Larsen C has calved, forming one of the largest icebergs ever observed.

The UK government has revealed how investing in the space industry will form a key part of its strategy for boosting economic growth.

At the heart of the government’s strategy is a pledge to invest £99 million to create a National Satellite Testing Facility (NSTF) and another £4 million investment for a new National Space Propulsion Facility (NSPF).

John Bucknell was Senior Propulsion Engineer for the Raptor full-flow staged combustion methalox rocket at SpaceX and is currently the Senior Propulsion Scientist for Divergent3D in Torrance, CA developing additively manufactured vehicle technologies.

In 2015, Bucknell presented the Nuclear Thermal Turbo rocket which added air-breathing to a nuclear thermal rocket.
