For real though, we should be launching rovers and satellites in every launch window (about every 2 years i think). Make another Percy and launch that SOB in 2022.

Ginny's 6th flight- now into uncharted territories- had some hiccups. Triple Lindig redundancies and foresight in design allowed it to make it through ok.
On the 91st Martian day, or sol, of NASA’s Mars 2020 Perseverance rover mission, the Ingenuity Mars Helicopter performed its sixth flight. The flight was designed to expand the flight envelope and demonstrate aerial-imaging capabilities by taking stereo images of a region of interest to the west. Ingenuity was commanded to climb to an altitude of 33 feet (10 meters) before translating 492 feet (150 meters) to the southwest at a ground speed of 9 mph (4 meters per second). At that point, it was to translate 49 feet (15 meters) to the south while taking images toward the west, then fly another 164 feet (50 meters) northeast and land.
Telemetry from Flight Six shows that the first 150-meter leg of the flight went off without a hitch. But toward the end of that leg, something happened: Ingenuity began adjusting its velocity and tilting back and forth in an oscillating pattern. This behavior persisted throughout the rest of the flight. Prior to landing safely, onboard sensors indicated the rotorcraft encountered roll and pitch excursions of more than 20 degrees, large control inputs, and spikes in power consumption.

Meanwhile, Curiousity is still going strong.
Link to an article about clouds it's been documenting. The gif images of the clouds moving by are outstanding.

Probably that Canadian made piece of crap. Those cannucks think they are so cool with their robot arms.

When they say 'space junk', my assumption is 'man-made'. Do they know this? Or could it have just been an asteroid / etc

Ginny made its 7th and 8th flights successfully flying out ahead of Percys route. They are planning to continue flying a couple times per month until they can't...far surpassing her originally planned for 5 flights and pushing the research towards future joint rover/drone missions.
And China ramping up the new space race...
GUANGZHOU, China — China plans to send its first crewed mission to Mars in 2033 as it continues to boost its space ambitions in a battle with the U.S.
The world's second-largest economy is planning regular crewed missions to the Red Planet.
Wang Xiaojun, head of the state-owned China Academy of Launch Vehicle Technology, outlined the country's Mars plans for the first time this month at a space conference in Russia, according to the academy.
It comes just weeks after China landed a remote-controlled rover called Zhurong on Mars, making it the only country after the U.S. to do so.
Wang said the first step in China's plans is to use robots to explore Mars to sample its surface and help select a place to build a base. The next stage would be to send astronauts up to Mars to build a base station there. Then China wants large-scale Earth-to-Mars cargo missions.
China has earmarked 2033, 2035, 2037, 2041 and 2043 for such missions and said it will explore technology to fly astronauts back to Earth.
A roundtrip to Mars would have a flight time of "hundreds of days," the academy said.

Does anyone doubt that if China put forth the effort they could surpass the capabilities of the US in space?
They aren't there yet, but that cutoff change in less than 10 years. The hope of the US is in private enterprise to push the envelope, but that might not bear as much fruit as a centralized effort that can leverage state resources.

Live feed on twitter - about to do the release from the plane.

Ginny keeps on cruising, btw. Ran its 9th flight last week- this one the longest and fastest and first over more varied terrain. Also first time being used operationally- the data it recorded will help Percy travel faster and more efficiently across the crater to its next spot.

Hooray rich people.
Bezos and Branson...i havent followed as much, but its basically space tourism for the rich? Or are there other things coming out of this...?
According to the broadcast there is a lot that can come from this. One is sending people to space to do work and research that can not be done on earth.

Getting rich people interested in space is probably smart.
So this was pretty cool:
BREAKING: At 82 years old, pioneering female pilot Wally Funk becomes oldest person to fly to space. She was once told, "Wally, you're a girl, you can't do that."

Elon actually found a functional reason to do this though. The others just want to be Nasa2.0 or a tourism farm.

Plane rides were only for the rich for a long time. Hopefully eventually we’ll hit a place where suborbital flight becomes cheap enough that normal folks can take a 45 minute flight from NYC to Hong Kong. Also, this is a step in the process of sending people to Mars. Who knows where that goes eventually.
A lot of research and eventually commercial products/applications have come from the space program as well. Having private companies involved may speed that up.

Definitely things will come from this beyond rich people going to space... I just hadnt read any direct applications they were pursuing with it. As Culdeus said, Musk approached this differently...which I respect.

Let's look 10-15 years in the future. Odds are nobody is going overseas by air for either lack of fuel or climate change reasons by anything but boat.

Yeah, probably not physics proper, but this is the thread I lean on for fascinating science topics.
