Apple’s M1 chip is Apple’s fastest single-core CPU benchmark on a Mac, and it beats many high-end Intel competitors in multi-core performance. Developer Erik Engheim recently shared an in-depth look at the M1 chip, exploring why Apple’s new processor is so much faster than the Intel chip it replaces. M1 is not a CPU! First, the M1 is not a simple CPU. As Apple explains, itR...
On November 14th, according to foreign media reports, on Wednesday local time, SpaceX, the US space exploration technology company, started the emergency escape engine of its Crew Dragon spacecraft during a ground test in Cape Canaveral, Florida. , paving the way for key test flights in the coming months. If the test flight goes well, SpaceX will carry humans on its Crew Dragon spacecraft for the first time next year.
The emergency escape engine is a key component of the Crew Dragon, which activates if an accident occurs during launch. The spacecraft will carry SpaceX’s Falcon 9 rocket into space, but if for some reason the rocket fails in mid-air, emergency escape engines embedded in the spacecraft’s outer shell will fire and bring the capsule to safety. The capsule will then land using the parachute it carries.
These emergency escape engines, known as SuperDracos, have been in the spotlight recently. In April, a Crew Dragon test capsule exploded after starting its engines a few times during a routine test. SpaceX immediately set up a dedicated team to investigate the cause, and it was eventually discovered that the leaking valve caused propellant from the engine to enter another system, triggering a chain reaction. SpaceX assured the public that it will redesign the system and replace the valves.
The latest test means SpaceX’s investigation into the accident has concluded and the company can move forward as scheduled. At the same time, this test also means that SpaceX is about to conduct its next important test, which is to test the emergency escape engine in flight. So far, SpaceX has only tested the system on the ground.
Now, SpaceX wants to see if SuperDracos can perform just as well on a real rocket. At some point in the future, SpaceX plans to launch a used Falcon 9 rocket from Cape Canaveral, Florida, with a test Crew Dragon capsule on top. After launch, the spacecraft’s emergency escape system will activate and attempt to drive the capsule away from the rocket.
Once the tests are complete, SpaceX will complete most of the test flight requirements for the Commercial Astronaut program, and its last major test will be its first crewed test flight, sending two NASA astronauts to the International Space Station for a brief stop, Then return to Earth. If the test is successful, SpaceX will receive final qualifications to begin regularly transporting astronauts to the International Space Station. SpaceX could launch as early as the first half of 2020, but any unforeseen issues could delay the plan.
