The Nasa instagram is an absolute horror show - 90% moon landing conspiracy nuts and flat earthers comprise the comments section.  Sorry, I've never vented that anywhere and noticed this thread was available.

R.I.P. Opportunity: https://www.nationalgeographic.com/science/2019/02/nasa-mars-rover-opportunity-dead-what-it-gave-humankind/

After a 14.5 year journey and 28+ mile trek, its efforts have not been in vain. For one, water with neutral pH confirmed on Mars about 4B years ago, thanks to Opportunity. That and NASA have already officially hinted at Meridiani Planum, Opportunity's landing site, as a potential LZ for human exploration later this century.

That produced a fairly big bang, releasing as much energy as about 170,000 tons of TNT — more than ten times the yield of the bomb dropped on Hiroshima at the end of World War II. It was just under 26 km above the Earth’s surface when this happened.

 
Had you been under it at the time you would have seen a very bright flash, and then, about a minute later, a pretty loud boom.

NASA Offering People $19,000 To Stay In Bed For Two Months

 

https://pittsburgh.cbslocal.com/2019/03/27/nasa-offering-people-19000-to-stay-in-bed-for-two-months/

 


CAPE CANAVERAL, Fla. (KDKA) — Do you want to make money, but never leave your bed? NASA just may have your dream job.

 

According to CBS-affiliate WKMG, researchers and NASA and the European Space Agency are willing to pay 24 participants nearly $19,000 to spend 60 days in bed and monitored around the clock.

 

The 24 participants will be separated into two groups, but housed in a single room. Each person will be propped up at an incline with their feet above their head, reducing blood flow to the extremities, mimicking the effects of being in space. This could, however, lead to numbness and muscle deterioration.

 

Participants will also be asked to do a number of activities lying down such as eating, reading, watching TV or going to the bathroom.

The compensation is 16,500 pounds, which works out to $18,565.

 

One group will be spun around in a centrifuge, akin to an artificial gravity chamber, which will force blood back into their extremities. The other group will not be spun.

 

Scientist hope by comparing the groups they will learn whether “artificial gravity” will be helpful during long-term space travel.

Like most dream jobs, the offer comes with a catch. You must speak German and be between 24 and 55 and healthy.

 

Those interested can apply here.

 

 

Since it's technically a 24/7 job, you'd actually be making less than minimum wage.

That's a really terrible job offer.  I don't imagine many people would last more than a couple weeks before realizing they'd made a huge mistake and quitting.  It's an alright deal if you're already bedridden I suppose.

'A terrible thing': India's destruction of satellite threatens ISS, says Nasa

Space agency chief says shooting down of satellite has created 400 pieces of orbital debris


India’s destruction of one of its satellites has been labelled a “terrible thing” by the head of Nasa, who said the missile test created 400 pieces of orbital debris and posed a threat to astronauts onboard the International Space Station (ISS).

 

Jim Bridenstine was addressing employees five days after India shot down a low-orbiting satellite in a missile launch that it says elevated the country to the elite tier of space powers.

 

The satellite shattered into pieces, many of which are dangerously large but too small to track, Bridenstine said. “What we are tracking right now, objects big enough to track – we’re talking about 10cm (six inches) or bigger – about 60 pieces have been tracked.”

The Indian satellite was destroyed at a relatively low altitude of 180 miles (300km), well below the ISS and most satellites in orbit.

 

But 24 of the pieces were going above the ISS, said Bridenstine. “That is a terrible, terrible thing to create an event that sends debris at an apogee that goes above the International Space Station,” he said, adding: “That kind of activity is not compatible with the future of human spaceflight.”

 

“It’s unacceptable and Nasa needs to be very clear about what its impact to us is.”

 

The US military tracks objects in space to predict the collision risk for the ISS and for satellites. They are tracking 23,000 objects larger than 10cm. That includes about 10,000 pieces of space debris, of which nearly 3,000 were created by a single event: a Chinese anti-satellite test in 2007, 530 miles above the surface.

 

As a result of the Indian test, the risk of collision with the ISS has increased by 44% over 10 days, Bridenstine said. But the risk will dissipate over time as much of the debris will burn up as it enters the atmosphere.

 

India’s ministry of external affairs said at the time of the launch the test was done in the lower atmosphere to ensure that there is no space debris. “Whatever debris that is generated will decay and fall back onto the earth within weeks,” it said.

 

The missile test was celebrated in India but also drew criticism because it was announced by the prime minister, Narendra Modi, while the government is supposed to be in caretaker mode before elections starting this month.

There are estimated to be about 900,000 pieces of debris larger than a marble in orbit around the earth, according to statistical models cited by the European space agency. There are about 34,000 objects circulating that are larger than 10cm.

 

Even collisions with tiny objects can be catastrophic in space, largely due to the pace at which spacecraft are moving in orbit, a minimum of 7.8km per second.

Toyota's Planned Moon Rover With 18 Times the Range of Model S

 

 

In March, the company announced that it’s joining forces with Japan’s space agency — JAXA — to build and launch a new electric buggy into space by 2029.

 

 

The vehicle is still in its early, conceptual stages and the both Toyota and JAXA have yet to decide on a name or finalized design. But a few key design elements have already been decided upon: The pair want it to both run on clean-energy and be capable of extremely lengthy lunar road trips. In a press release, Toyota stated it’s aiming for a cruising range of 6,214 miles, only 572 miles short of the moon’s total circumference, and more than double the width of the United States.
