The inclusion of an ion propulsion system in a long-running, Earth-orbiting space station will give researchers a chance to test out the tech while astronauts are still close to home — and if it works as hoped, it could one day ferry explorers to Mars and even more distant destinations.
“When they did that design, they should have stopped and thought, ‘you know, that’s going to leave a big chunk of debris in orbit, we should change the design of the engine’,” McDowell says. “But they didn’t. This is real negligence.”
Four years ago, China’s first space station landed in the Pacific Ocean between Australia and Chile, after an uncontrolled reentry. China didn’t care.
Last year, pieces from a Long March 5B rocket landed in Cote d’Ivoire. They damaged buildings in two villages. China didn’t care.
This launch of the same rocket design could land anywhere from New York to New Zealand, covering a wide range of habitation. China doesn’t care.
On the other hand, once somebody in their government reads about the criticism by the scientific community, they’ll petulantly whine that this often happened in the 1960s, so that makes it OK for them to ignore rocket safety designs known for the past 30 years.
Maybe it’s technology they haven’t yet stolen from other countries.
As the self-acknowledged center of the known universe, the Middle Kingdom only cares what others think of it. Like a spoiled child that thinks it knows everything but fears it does not, China only reacts to its own mistakes by lashing out at others and disclaiming responsibility.
If you want to be respected as a superpower, you need to learn how to respect other countries and stop dumping your trash on them. Respect is not given, it is earned. China has done little to earn any respect by the scientific community.
…but seriously, this is neat. One source of the X-Rays is the Sun (it also bounces off of Jupiter and Saturn). But there may be yet another source…perhaps the rings of Uranus or the planet itself.
And no, it’s not really pink. That’s just a Chandra X-ray image.
Great job, NASA! Landing on Mars is always a tricky business.
Now all Perseverance has to do is find traces of life, save it without contamination, and then wait for another rocket, another rover, and a satellite to get in orbit so the samples can be sent back to Earth.
Critics of the Planet Nine claim said the apparent clustering of the discovered TNOs might only be because that’s where telescopes were looking or were most sensitive.
If you are looking to find evidence to prove your theory, it’s much easier to find what you’re looking for.
You should instead try to find evidence to disprove your theory, and then ask at least two more people you don’t know (or even better, generally disagree with) to try to find evidence to support your theory.
“Seek and ye shall find” is a terrible way to support a claim. Have the courage to challenge your beliefs.
Also, it’s Planet X, not 9. Pluto is a planet. So there, Neil deGrasse Tyson. :-p
A crewed mission to Mars may be more practical thanks to a new rocket concept developed by Fatima Ebrahimi, a physicist at the US Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), that uses magnetic fields to generate thrust.
