Navigating Deep Space by Starlight
On August 6, 1967, astrophysicist Jocelyn Bell Burnell noticed a blip in her radio telescope data. And then another. Eventually, Bell Burnell figured out that these blips, or pulses, were not from people or machines.
Tumblr media
The blips were constant. There was something in space that was pulsing in a regular pattern, and Bell Burnell figured out that it was a pulsar: a rapidly spinning neutron star emitting beams of light. Neutron stars are superdense objects created when a massive star dies. Not only are they dense, but neutron stars can also spin really fast! Every star we observe spins, and due to a property called angular momentum, as a collapsing star gets smaller and denser, it spins faster. It’s like how ice skaters spin faster as they bring their arms closer to their bodies and make the space that they take up smaller.
Tumblr media
The pulses of light coming from these whirling stars are like the beacons spinning at the tops of lighthouses that help sailors safely approach the shore. As the pulsar spins, beams of radio waves (and other types of light) are swept out into the universe with each turn. The light appears and disappears from our view each time the star rotates.
Tumblr media
After decades of studying pulsars, astronomers wondered—could they serve as cosmic beacons to help future space explorers navigate the universe? To see if it could work, scientists needed to do some testing!
First, it was important to gather more data. NASA’s NICER, or Neutron star Interior Composition Explorer, is a telescope that was installed aboard the International Space Station in 2017. Its goal is to find out things about neutron stars like their sizes and densities, using an array of 56 special X-ray concentrators and sensitive detectors to capture and measure pulsars’ light.
Tumblr media
But how can we use these X-ray pulses as navigational tools? Enter SEXTANT, or Station Explorer for X-ray Timing and Navigation Technology. If NICER was your phone, SEXTANT would be like an app on it.  
During the first few years of NICER’s observations, SEXTANT created an on-board navigation system using NICER’s pulsar data. It worked by measuring the consistent timing between each pulsar’s pulses to map a set of cosmic beacons.
Tumblr media
When calculating position or location, extremely accurate timekeeping is essential. We usually rely on atomic clocks, which use the predictable fluctuations of atoms to tick away the seconds. These atomic clocks can be located on the ground or in space, like the ones on GPS satellites. However, our GPS system only works on or close to Earth, and onboard atomic clocks can be expensive and heavy. Using pulsar observations instead could give us free and reliable “clocks” for navigation. During its experiment, SEXTANT was able to successfully determine the space station’s orbital position!
Tumblr media
We can calculate distances using the time taken for a signal to travel between two objects to determine a spacecraft’s approximate location relative to those objects. However, we would need to observe more pulsars to pinpoint a more exact location of a spacecraft. As SEXTANT gathered signals from multiple pulsars, it could more accurately derive its position in space.
Tumblr media
So, imagine you are an astronaut on a lengthy journey to the outer solar system. You could use the technology developed by SEXTANT to help plot your course. Since pulsars are reliable and consistent in their spins, you wouldn’t need Wi-Fi or cell service to figure out where you were in relation to your destination. The pulsar-based navigation data could even help you figure out your ETA!
Tumblr media
None of these missions or experiments would be possible without Jocelyn Bell Burnell’s keen eye for an odd spot in her radio data decades ago, which set the stage for the idea to use spinning neutron stars as a celestial GPS. Her contribution to the field of astrophysics laid the groundwork for research benefitting the people of the future, who yearn to sail amongst the stars.  
Keep up with the latest NICER news by following NASA Universe on X and Facebook and check out the mission’s website. For more on space navigation, follow @NASASCaN on X or visit NASA’s Space Communications and Navigation website.

meet the female engineer! she's part of the conagher family, though not as involved in the kind of engineering that her uncle and great uncle were in. despite being a very gifted mechanic, she preferred more domestic endeavours like tuning cars and air conditioning units. however, the promise of wads of cash and possibly seeing her cousin Dell made her conagher DNA jump into high gear upon seeing the blueprints for the sentries for the first time.
Tumblr media Tumblr media
the first question people often ask her is, "why the turtleneck?". the response from a less-than-human sounding voice often answers the question. thanks to an unfortunate "accident" she had her head lobbed from her shoulders and reattached. of course, such endeavors would be less than ideal for the normal person, but the engineer is known for her amazing inventions and with help from the medic she surgically reattached it. allegedly, not to her original body. at the very least, her back pain inexplicably went away after this incident. nervous system failure perhaps?

You know something? After watching quiet on set I don’t mind freaking 20 something year olds playing teen roles on screen bc holy shit.
TW:SA (not really mentioned on this rant but it’s surrounding the topic)
Grown ass people taking advantage of m*nors is so disgusting, I feel disgusted for even liking these shows growing up, specially now that I know the truth. This is insane.
And some of the PARENTS. Gosh, YOURE NOT SUPPOSE TO BE FRIENDS WITH YOUR CHILDREN. BE A PARENT. You’re their guide/mentor, you’re suppose to protect them from the bad and evil, even if you think they might resent or hate you for it, or hell! Even if this kills their career. BUT they will understand when they grow older. They’ll be thankful. And when they’re older y’all can be as best friends as you want, but when they’re young and naive (sorry for the lack of better word) you have to be the adult in that situation and protect them. It’s not a popularity contest, it’s a take better care of your kids type of contest.

I love how Spider-Man: Into the Spider-Verse said “Anyone can be Spider-Man”. I love how it inspired everyone to imagine their own Spider-People, saving the day in their own universes, with all kinds of cool, interesting personalities and aesthetics and mutations and life stories and relationships. We all put pieces of our soul into these homemade heroes. We had fun. We found community. And then Spider-Man: Across the Spider-Verse said, “Wow, great job! You’ve really taken our message to heart. Well, get ready for even more of everything you liked from the first movie and a new message to complement the first. Anyone can be Spider-Man… and anyone can be pulled into a cult.”
So now we all have to contemplate whether our lovingly crafted heroes would ever be on Team Mandatory Trauma Because Martyr Complex or not and why.

Summary: how someone like aventurine spends his days off
Gn!reader, established relationship, it's very short but I have to start somewhere
Tumblr media
Aventurine is a busy man, such is the life of being a senior manager in the IPC, he's needed in a lot of places every time he thinks he can get a breather his phone proceeds to ring nonstop until he picks it up and what do you know, he just got another assignment to another planet aeon knows where.
But, there are times when that's not the case, like everyone else the blonde sigonian has days where he's not working, where he's legally allowed to chuck his phone at the mention of work, not that he'd actually do such a thing, he'd never hear the end of it from Ratio from doing something so stupid, even if he has the money for it.
His subordinates wonder often what could he possibly be doing on those days where he's practically unreachable, making elaborate theories such as him visiting casinos and placing bets that will ultimately make him richer than he is now, or participating in biddings of priceless relics, unfortunately for them he's far more simpler than that.
He spends his day in the comfort of his partner's home and to that extent, their company, practically leeching himself to them for the majority of his time of being a free man away from his duties, it's practically impossible to go about your day without aventurine following you around like a lost puppy.
And that's because he wants to spend every precious moment together with his beloved, making up for all the lost time due to how gruelling his occupation is, he could be doing the most mundane things and it wouldn't matter because he's with you.
Even when it's time to sleep, his arms are wrapped around you while you rest, he can't help but think about his next day off, where he's planning to spend the day with you again.
