SpaceX has rapidly recovered the first converted Falcon Heavy ‘side core’ after its first Falcon 9 launch and landing, kicking off preparations for its fourth launch less than two days after its third.

After four consecutive days of delays, one of which was caused by an inexplicably wayward cruise ship, former Falcon Heavy side core B1052 finally lifted off on January 31st on its first mission as a Falcon 9 booster. Despite the painful launch campaign, B1052 performed perfectly and helped send the Italian Space Agency’s (ASI) CSG-2 Earth observation satellite to a polar sun-synchronous orbit (SSO) before boosting back to the Florida coast and landing just a few miles south of where it launched.

As a Falcon Heavy side core, B1052 supported both of the only two launches of the Block 5 variant of the rocket – first on April 11th, 2019 and again on June 25th, 2019. Both times, side boosters B1052 and B1053 performed return-to-launch-site (RTLS) maneuvers and landed side by side at SpaceX’s LZ-1 and LZ-2 landing pads. CSG-2 thus marked B1052’s third launch and third RTLS landing.

Feb 2 (Reuters) — State-owned China National Nuclear Corp (CNNC) has signed a contract in Argentina to build the $8 billion Atucha III nuclear power plant using China’s Hualong One technology, reviving a deal that had been stalled for years.

CNNC said on its WeChat account late on Tuesday that ithad signed an engineering, procurement and construction (EPC) contract, which comes ahead of Argentine President Alberto Fernandez’s trip to China later this week.

Progress on the nuclear deal between the two nations had stalled since it was first negotiated by the administration of former President Cristina Fernandez, a left-wing populist who left office in 2015. She is now Argentina’s vice president.

If scientists could measure the oscillations of just one energized cesium atom, they’d be able to keep perfect time, but they can’t due to a weird phenomenon called the standard quantum limit.

Instead, they have to measure thousands of atoms at once and then average out the results for atomic clocks, which leads to a just slightly imprecise second.

Now, MIT researchers have found a way to create a more precise atomic clock by exploiting another weird quantum phenomenon: entanglement.
