Another major workplace injury occurred at SpaceX last year:
SpaceX crane collapse in Texas being investigated by OSHA.

The crane collapse was captured in a livestream by Lab Padre on YouTube, a SpaceX-focused channel. Clips from Lab Padre were widely shared on social media, including on X, which is owned by SpaceX CEO Elon Musk. It wasn’t immediately clear whether any SpaceX workers were injured as a result of the incident. Musk and other company executives didn’t respond to a request for comment.

A heads up about how multi-billion dollar corporations operate. Whenever there is an accident where people were potentially injured, if there were no injuries the company quickly gets out there were no injuries. For instance like how SpaceX quickly got out there were no injuries during the static test explosion. But if the company makes no comment on the accident, it’s a good chance there were injuries. And the longer the company says nothing about the accident the more likely it becomes there were serious injuries.
Article from 2023 detailing SpaceX culture downplaying worker safety:
A REUTERS INVESTIGATION
At SpaceX, worker injuries soar in Elon Musk’s rush to Mars.

Reuters documented at least 600 previously unreported workplace injuries at Musk’s rocket company: crushed limbs, amputations, electrocutions, head and eye wounds and one death. SpaceX employees say they’re paying the price for the billionaire’s push to colonize space at breakneck speed.

More Raw data
Been going through the Roman Space Telescope specs this week and honestly the scale of what this thing is supposed to do is hard to wrap your head around.
Same size mirror as Hubble — 2.4 meters.
But the camera covers a field 100 times larger.
In one 6-minute exposure it photographs more sky than Hubble observes in a year. To survey the area Roman will cover in its first 12 months, Hubble would need over 1,000 years of continuous observation.
It's also designed to map dark energy across 2 billion galaxies — the first time we'll actually have data on what's accelerating the expansion of the universe. And it's going to find somewhere between 2,500 and 100,000 new exoplanets through gravitational microlensing.
The part that got me was the story of Nancy Grace Roman. She invented the concept of Hubble in 1969, wasn't invited to the launch, spent the rest of her career as a contractor at the same institution she built, and died in 2018 — two years before NASA named this telescope after her.
Launches October 2026 on a Falcon Heavy to L2.
Made a full breakdown of everything it's going to do and why the dark energy results might be the most important data we've ever collected
Anyone else been following this one?
Engulfed in dark molecular clouds of interstellar dust and surrounded by other deep space objects such as the Ghost Nebula (Sh 2-136), the Iris Nebula makes a stunning statement with its beautiful blue hues. A bright flower in a garden of irradiated soil.
1,600 years ago, as the Roman Empire was collapsing and the Mayan Dynasty was born, the light in this photo began its journey to my telescope. This is the second time I’ve captured it — the first time being when I was just dipping my toes into astrophotography. After 8 months in the hobby, I’ve learned so much and expanded my understanding in ways I never anticipated.

My first astrofotography setup is finally ready! Just waiting for the guidescope and camera to make it complete but I’m already gonna try it out on the first clear night I get because I’m so hyped. I’m also saving up for a better telescope like an APO,ED doublet/triplet/petzval or whatever to upgrade the lens. Also considering on buying an CLS/UHC filter because I live in a bortle 6 region.
Equipment:
- Canon 500D EOS (unmodded)
- Sigma DC 18-200mm (f/3.5-6.3) lens
- some cheap bahtinov mask, dew heater and dovetail from amazon
- ACK-E5 Battery dummy for Canon EOS
- Svbony 905C Guiding cam
- Svbony SV165 Guidescope
- 3D printed hot shoe for adapting my guidescope

This is my first attempt at photographing a galaxy. I have a lot to learn and there is huge room for improvement but I had a lot of fun with this and can’t wait for the next clear night.
About 15 hours of data captured over 4 sessions.

This is an RGB color-composite made from images taken by NASA's Opportunity rover on May 6, 2004
2 minutes exp 60 second exp some stacked in helicon
Camera: Sony A6400 (no mod),
Lens: Samyang 135mm f/2,
Mount: Skywatcher HEQ5,
Sky: Bortle 5, no moon.
Around 400 of 30 s subs pre-processed, stacked and post-processed in Siril with a pretty standard procedure. However due to moderate light pollution quadratic background extraction was applied already at sub level. Shot at f/2.8, ISO 400.
Visible near the upper right corner is the Crescent Nebula (NGC 6888). The halo around Sadr is a result of lens optics and I did not attempt to remove it. A reflection nebula near the lower left corner around 44 Cygni is also visible.
This glowing ring is RCW 86, the remnant of an 2000 year old supernova explosion observed by multiple NASA telescopes.
NASA’s IXPE telescope recently studied a section of the remnant where scientists believe the expanding shockwave slammed into the edge of a low-density “cavity” in space, creating the reflected shock effect visible in purple.
The image combines data from:
NASA’s IXPE
Chandra X-ray Observatory
ESA’s XMM-Newton telescope
NOIRLab starfield data
Yellow shows lower-energy X-rays, while blue represents higher-energy X-rays. The result looks almost like a cosmic painting across space.

NASA's Ingenuity Mars Helicopter completed 72 historic flights since first taking to the skies above the Red Planet.
On April 19, 2021, NASA's Ingenuity Mars Helicopter made history when it completed the first powered, controlled flight on the Red Planet. It flew for the last time on Jan. 18, 2024.
Designed to be a technology demonstration that would make no more than five test flights in 30 days, the helicopter eventually completed 72 flights across nearly three years, soaring higher and faster than previously imagined. Ingenuity embarked on a new mission as an operations demonstration, serving as an aerial scout for scientists and rover planners, and for engineers ready to learn more about Perseverance’s landing-gear debris.
In its final phase, the helicopter entered a new engineering demonstration phase where it executed experimental flight tests that further expanded the team’s knowledge of the vehicle’s aerodynamic limits.
